Novel environment-friendly flame-retardant wood profile and manufacturing method thereof
Technical Field
The application relates to the technical field of flame-retardant wood profiles, in particular to a novel environment-friendly flame-retardant wood profile.
Background
The wood material is a natural material, has excellent visual, tactile and auditory environmental characteristics, has excellent strength-to-weight ratio, and is incomparable with other materials (such as wood plastic, straw wood shavings, stone, metal materials and the like). Wood materials are often used for interior finishing of homes, public places, and vehicles, and their flame retardant properties are important indicators for wood products.
The flame retardant wood profiles of the prior art generally comprise 3 forms: the first is to compound a wood material with a physically flame retardant material, such as the wear-resistant flame retardant floor disclosed in chinese patent 201120279673.7, which achieves a certain flame retardant effect by bonding aluminum oxide wear-resistant paper on the surface of a wood substrate; the second is to densify and impregnate the wooden material, as disclosed in chinese patent 201210457197.2, a compressed flame retardant profile, which achieves the flame retardant effect of the wooden profile by densifying the fast-growing wood, followed by impregnating with a chemical flame retardant agent; the third is to impregnate the wood material with the flame retardant agent, such as a flame retardant and wear resistant solid wood composite floor disclosed in China patent 200720187592.8, wherein the solid wood material is subjected to the impregnation of the flame retardant agent and then is bonded with an aluminum oxide wear resistant layer (the aluminum oxide particles in the wear resistant layer are mainly used for wear resistance).
For the first flame-retardant section bar and the flame-retardant method thereof, the flame-retardant effect only depends on the flame-retardant effect of the aluminum oxide wear-resistant paper, the aluminum oxide consumption of the aluminum oxide wear-resistant paper is insufficient, the flame-retardant effect is poor, the aluminum oxide consumption is sufficient, and the manufacturing cost is too high; for the second and third flame-retardant profiles and the flame-retardant method thereof, although various flame-retardant additives can achieve good flame-retardant effect, part of flame-retardant agents can form toxic gas during combustion (namely flame retardance), so that the risk of fire is improved, meanwhile, the dipping treatment time for dipping the flame-retardant agents is longer, the drying and curing time after treatment are also relatively longer, and therefore, the production period is long and the production efficiency is low.

Detailed Description
The following describes the embodiments of the present invention in further detail with reference to examples. The following examples are illustrative of the invention and are not intended to limit the scope of the invention.
Example 1: the novel environment-friendly flame-retardant wood profile shown in the reference figure sequentially comprises a first flame-retardant adhesive layer 200, a base material layer 100 and a second flame-retardant adhesive layer 300 which are bonded with each other from top to bottom, wherein an upper flame-retardant reinforcing layer 110 is formed at the upper layer part of the base material layer 100 in the thickness direction. Wherein, the first flame retardant adhesive layer 200 and the second flame retardant adhesive layer 300 are aluminum oxide adhesive papers. Specifically, the upper flame retardant reinforcing layer 110 of the present application refers to a thickness portion having an air dry density of not less than 1000kg/m 3, preferably 1000kg/m 3-1500kg/m3 (e.g., 1200 kg/m 3).
With the above structure, the novel environment-friendly flame-retardant wooden section of the present embodiment forms a relatively effective flame-retardant effect by using the substrate layer 100 having a relatively large air-dry density and matching with the first and second flame-retardant adhesive layers 200 and 300 through the upper flame-retardant reinforcing layer 110 formed on the upper layer (surface layer and the portion below the surface layer) of the substrate layer 100 in the thickness direction; meanwhile, the substrate layer 100 having a relatively high air-dry density and the first and second flame retardant adhesive layers 200,300 have physical flame retardance, so that no toxic gas is generated during the combustion process (flame retardant process), and are relatively safe.
In the present embodiment, the substrate layer 100 is one of a medium/high density fiber board, a multi-layer plywood, a three-layer plywood, a wood shaving board, a solid wood board, a finger joint board and an integrated board. The thickness of the base material layer 100 is designed to be 6 mm, 8, 10, 12, etc. according to the product design requirement, and the thickness of the upper flame-retardant reinforcing layer 110 accounts for 5% -10% of the total thickness of the base material layer 100. Theoretically, the greater the thickness of the upper flame retardant reinforcing layer 110, the better the flame retardant effect thereof, that is, the upper flame retardant reinforcing layer 110 may occupy the entire thickness of the substrate layer 100, but from the viewpoints of production efficiency, material loss rate (material thickness loss), correspondence between the thickness of the upper flame retardant substrate layer 110 and flame retardant effect, etc., the preferable minimum thickness of the upper flame retardant layer 110 is 5% of the total thickness of the substrate layer 100, and the preferable maximum thickness is 10% of the total thickness of the substrate layer 100. That is, when the thickness of the base material layer 100 is 10mm, the thickness of the upper flame retardant reinforcing layer 110 should be 0.5mm to 1mm.
The first flame retardant adhesive layer 200 and the second flame retardant adhesive layer 300 are melamine adhesive papers added with aluminum oxide particles, and are adhered to the substrate layer 100 through the self-heating and melting viscosity. Preferably, the first flame retardant ply 200 is a melamine decal with added aluminum oxide particles in an amount of 45 g/square meter and the second flame retardant ply is a melamine decal with added aluminum oxide particles in an amount of 30 g/square meter or 33 g/square meter.
For convenience of surface decoration, it is preferable that the first wood veneer layer 400 is adhesively disposed on the surface of the first flame retardant coating layer 200 and the second wood veneer layer 500 is adhesively disposed on the bottom surface of the second flame retardant coating layer 300. The surface of the first flame retardant coating 200 is a surface opposite to the bonding surface to which the substrate layer 100 is bonded, and the bottom surface of the second flame retardant coating 300 is a surface opposite to the bonding surface to which the substrate layer 100 is bonded. The bonding between the first wood veneer layer 400 and the second wood veneer layer 500 and the first flame-retardant adhesive layer 200 and the second flame-retardant adhesive layer 300 is realized by the viscosity of the first flame-retardant adhesive layer 200 and the second flame-retardant adhesive layer 300 after self-heating and melting. In this embodiment, the first wood veneer layer 400 and the second wood veneer layer 500 are rotary-cut wood veneers having a thickness of 0.3mm to 0.5mm (preferably 0.5 mm). The first wood veneer layer 400 and the second wood veneer layer 500 are arranged to improve the flatness of the surface and the back of the novel environment-friendly flame-retardant wood section bar, thereby being beneficial to the arrangement of decorative surfaces.
When the novel environment-friendly flame-retardant wood profile in the technical scheme of the application is used as a novel reinforced floor/wallboard, the novel environment-friendly flame-retardant wood profile can be realized by bonding the decorative layer 600 on the surface of the first wood veneer 400 and the balance layer 700 on the bottom surface of the second wood veneer 500. The decorative layer 600 is a decorative layer comprising decorative paper and wear-resistant paper, and the balancing layer 700 is any melamine balancing paper in the prior art.
When the novel environment-friendly flame-retardant wood profile in the technical scheme of the application is used as a novel composite floor/wallboard, the novel environment-friendly flame-retardant wood profile can be realized by bonding the decorative layer 600 on the surface of the first wood veneer 400 and the balance layer 700 on the bottom surface of the second wood veneer 500. The decorative layer 600 is a veneer made by rotary cutting or planing, the thickness is 0.2mm-6mm, and the balance layer 700 is a rotary cut veneer with the thickness of 0.2mm-0.5 mm.
In particular, a heat dissipation layer 800 may also be disposed over the decorative layer 600, the heat dissipation layer 800 being a metal coating. The heat sink layer 800 may be a metal spray coating, such as a metal spray paint with aluminum oxide particles, sprayed over the decorative layer 600 by a spray coating process. The heat dissipation layer 800 may also be an aluminum oxide sticker, and in this case, the heat dissipation layer 800 is attached to the decorative layer 600 by hot pressing.
The novel environment-friendly flame-retardant wood profile of the embodiment is manufactured and produced by the following manufacturing method:
S1, a step of substrate treatment, wherein in the step of substrate treatment, the substrate layer 100 is subjected to hot pressing treatment, so that an upper flame-retardant reinforcing layer 110 is formed on at least the upper layer of the substrate layer 100 in the thickness direction, and the air-dry density of the upper flame-retardant reinforcing layer 110 is not lower than 1000kg/m 3;
s2, a compounding step, in which the first flame-retardant adhesive layer 200, the substrate layer 100 obtained in the substrate treatment step and the second flame-retardant adhesive layer 300 are placed in sequence from top to bottom, and the first flame-retardant adhesive layer 200, the substrate layer 100 and the second flame-retardant adhesive layer 300 are subjected to hot-pressing compounding, wherein the hot-pressing temperature is 100-150 ℃.
By means of the above manufacturing method, the manufacturing method of the novel environment-friendly flame-retardant wooden section improves the density of the substrate layer through physical hot pressing treatment, and bonds the first flame-retardant adhesive layer 200 and the second flame-retardant adhesive layer 300 on the upper surface and the lower surface of the substrate layer 100 through physical hot pressing treatment, so that the flame-retardant treatment method is a pure physical method, and compared with modification treatment of chemical agents, the method has no chemical agent addition and no pollutant formation, and is relatively environment-friendly. Meanwhile, the chemical agent impregnated flame retardant treatment method needs longer impregnation treatment time and longer secondary drying and curing treatment time, but the manufacturing method of the technical scheme of the application only needs two hot pressing treatments, and then the novel environment-friendly flame retardant wooden section bar of the technical scheme of the application is subjected to time-adjusting treatment, and does not need drying and curing treatment, so that the flame retardant treatment time is shortened, and the manufacturing method has relatively higher production efficiency while relatively higher flame retardant effect is achieved.
In the step of substrate treatment, the hot pressing temperature (temperature of the upper hot pressing plate) is 100 ℃ to 150 ℃, the hot pressing pressure is 7.0MPa to 12.0 MPa, the hot pressing time is 50s to 400s, and the temperature of the lower hot pressing plate is normal temperature, but the temperature of the lower hot pressing plate is about 60 ℃ under the influence of the upper hot pressing plate. Those of ordinary skill in the art will appreciate that the density and thickness of the upper flame retardant reinforcing layer 110 formed can be controlled by controlling the hot press temperature (upper hot press plate temperature), hot press pressure, hot press time. For example, the substrate layer 100 is a composite multi-layer board with a thickness of 10mm, and the initial water content is 12% -16%:
(1) The hot pressing temperature (temperature of the upper hot pressing plate) is 100 ℃, the hot pressing pressure is 7.0MPa, the hot pressing time is 50s, and after the step of treating the base material, the upper layer of the base material layer 100 forms an upper flame retardant reinforcing layer 110 with the thickness of about 0.5mm plus or minus 0.5mm and the density of about 1000kg/m plus or minus 50 kg/m;
(2) The hot pressing temperature (temperature of the upper hot pressing plate) is 150 ℃, the hot pressing pressure is 12.0MPa, the hot pressing time is 400s, and after the step of treating the base material, the upper layer of the base material layer 100 forms an upper flame retardant reinforcing layer 110 with the thickness of about 1mm plus or minus 0.5mm and the density of about 1500kg/m plus or minus 50 kg/m;
(3) The upper flame retardant reinforcing layer 110 having a thickness of about 0.8 mm.+ -. 0.5mm and a density of about 1200 kg/m.+ -. 50 kg/m was formed on the upper layer of the base material layer 100 after the step of treating the base material, in which the hot pressing temperature (temperature of the upper hot pressing plate) was 120 ℃, the hot pressing pressure was 10.0MPa, and the hot pressing time was 200 s.
It should be noted that, the composite multi-layer board is formed by laminating and compounding the rotary-cut wood veneer layer and the adhesive, so in this embodiment, the density of the upper flame-retardant reinforcing layer 110 is the air-drying density of the rotary-cut wood veneer layer and the adhesive as a whole.
In the compounding step, any lamination compounding process in the prior art can be adopted, for example, the hot pressing temperature is 120 ℃, the hot pressing pressure is not adopted, and the hot pressing time is 8s-20s. The compounding step is mainly to bond the upper and lower surfaces of the substrate layer 100 by hot-melting the first and second flame retardant adhesive layers 200,300 to form an adhesive.
When the novel environment-friendly flame-retardant wood profile in the technical scheme of the application is used as a novel reinforced/composite floor/wallboard, in the step of compositing, a first wood veneer 400, a first flame-retardant veneer 200, a base material layer 100, a second flame-retardant veneer 300 and a second wood veneer 500 which are subjected to the step of processing the base material are sequentially placed from top to bottom, and the first wood veneer 400, the first flame-retardant veneer 200, the base material layer 100, the second flame-retardant veneer 300 and the second wood veneer 500 are subjected to hot-pressing compositing, wherein the hot-pressing compositing process is the same as that described above; subsequently, the decorative layer 600 and the heat dissipation layer 800 are placed on the composite blank, and the balance layer 700 is placed under the decorative layer and the heat dissipation layer, and the composite process is repeated again.
Example 2: embodiment 1 differs from embodiment 2 in that, referring to fig. 2, the substrate layer 100 further includes a core layer 120 and a lower flame retardant reinforcing layer 130 below the upper flame retardant reinforcing layer 110, where the upper flame retardant reinforcing layer 110, the core layer 120, and the lower flame retardant reinforcing layer 130 are made of the same material and are naturally connected, and the air-dry density of the lower flame retardant reinforcing layer 130 is not less than 1000kg/m, and the air-dry density of the core layer 120 is not less than 800 kg/m. Specifically, the air-dry density of the upper and lower flame-retardant reinforcing layers 110, 130 is 1000kg/m to 1500 kg/m, and the air-dry density of the core layer 120 is 800 kg/m to 900 kg/m.
By means of the above structure, the novel environment-friendly flame-retardant wood section of the embodiment forms the upper flame-retardant reinforcing layer 110 with relatively higher density, the core layer 120 with relatively lower density and the lower flame-retardant reinforcing layer 130 with relatively higher density in the thickness direction of the substrate layer 100, so that compared with the technical scheme of the embodiment 1, the technical purpose of flame retardance of the back of the novel environment-friendly flame-retardant wood section can be achieved. Meanwhile, the high-density thickness layer clamps the low-density thickness layer, and compared with the technical scheme that only the upper flame-retardant reinforcing layer is formed on the upper layer or the substrate layer 100 is integrally processed into the upper flame-retardant reinforcing layer, the flame-retardant effect of the wood profile can be greatly improved by matching the first flame-retardant adhesive layers 200 and the second flame-retardant adhesive layers 300.
