Abstract
The present invention is a high bend resisting strength light core plate, and it is to make sandwich layer with plant haulm segments such as corn stalk, sorghum stalks, spreads the material that improves bending strength with the bamboo reinforcement net of gluing etc. respectively on the two sides of this sandwich layer, through hot pressing or cold pressing and make.This kind light core plate has high-flexural strength, need not add inside casing wood, saves timber, can make large-breadth plates by using in advance, and the time spent can cut arbitrarily.Can also be through secondary operations on the light core plate two sides that makes coated with various ornament materials, make the light body plate that serves many purposes.
Description
The invention belongs to the technical field of making wood-based plate of vegetable stem.
The applicant once invented the light body plate of straw (CN86209421), should add inside casing wood in advance when producing this light body plate, thereby to consume a certain amount of timber, and must make certain components by certain specification, and the plate that can cut apart arbitrarily during the use that can not make large format in advance, thereby be subjected to certain limitation as commodity production.The bending strength of the light body plate of above-mentioned straw also feels not enough simultaneously, this light body plate is made when having various ostentatious sheet material in secondary operations, the phenomenon that may occur bending and deformation, top layer veneer different with endosexine veneer material (the former quality is better than the latter usually) for example, the stress on two sides is also just different, certainly will cause the generation of buckling phenomenon, makes product rejection, and the veneer of same better material is all used on the two sides, has improved cost again.
Purpose of the present invention is exactly to be further improved on the basis of No. 86209421 patents of CN, make the sheet material of making not add wooden frame in advance, and improve its bending strength, make a central layer of large format, this central layer can also can be made the light body plate with various ostentatious high-flexural strengths through secondary operations directly as commodity selling.
For this reason, the inventor proposes a kind of new design, promptly before being pressed into plate, adds bamboo reinforcement net etc. in blank, to improve its bending strength.
The manufacture method of high bend resisting strength light core plate of the present invention is as follows:
1, use straws such as corn stalk, sorghum straw, sunflower straw, hemp stalk, piemarker stalk and paulownia wood as core, thickness by desiring the coremaking plate is processed into certain length, for example 16mm-40mm, shown in the accompanying drawing 1, it closely is arranged in sandwich layer;
2, multiple on the above-mentioned sandwich layer two sides that sequences with bamboo reinforcement or bamboo reinforcement net.Bamboo reinforcement is wide to be 1.5-10mm, thick 0.3-2mm, and the order number of net is 1-3, shown in the accompanying drawing 2.Here said bamboo reinforcement or bamboo reinforcement net also useable glass silk or glass cross or cloth or wire or woven wire or Ge Zhong Seats etc. other material that can improve bending strength replace.Will be when spreading the material with above-mentioned raising bending strength respectively in sandwich layer top and bottom with its gluing, the latter can be a urine aldehyde glue, also can be phenol glue.
3, sequence core material and complete the material that improves bending strength after, at 120-130 ℃ and 5-7Kg/cm
2Condition under, carried out hot pressing 5 minutes, place a few hours after the release, cut out the light core plate that the unhairing limit promptly becomes high-flexural strength, shown in the accompanying drawing 3.The hot pressing here changes into colding pressing also can.The temperature of colding pressing is a room temperature.
Embodiment
Be arranged in the tight sandwich layer of 2030 * 1030 * 40.5mm with the segment of sorghum straw 40mm, at the bamboo reinforcement net that is coated with adhesive of its top and each multiple 2050 * 1050mm breadth of bottom, at 125 ℃ and 6Kg/cm
2Condition under hot pressing 5 minutes, release is after 3 hours, dismissing burr promptly becomes high bend resisting strength light core plate.Adhesive used herein is made into by 1000 gram urea-formaldehyde resin adhesives and 30 grams, 20% aqueous ammonium chloride solution.
4, an above-mentioned plate can also be through secondary operations, promptly multiple with veneer, PLASTIC LAMINATED, glued board, fiberboard, particieboard, gypsum panel, mould molding diamond plate, cement plate, parquet floor face and various decoration papers or the like on its surface, has more multiduty light body plate and make, as movable dwellings plate, furniture board, ceiling, indoor floor, a wallboard, panel for construction door leaf etc., the plate face of these plates all can reach straight requirement, and has high-flexural strength.
The advantage of light core plate of the present invention is the bending strength height, need not add inside casing wood in advance, thereby saves timber, can make large-breadth plates by using in advance, and the time spent can be cut apart arbitrarily.Can again with various ornament materials, make the high bend resisting strength light body plate that serves many purposes on the light core plate two sides through secondary operations in addition.
Claims (2)
1, a kind of method of making wood-based plate with vegetable stem, it is characterized in that cuts into chunks to line up with corn stalk or sorghum straw or sunflower straw or hemp stalk or plant haulms such as piemarker stalk or paulownia wood makes sandwich layer, spread bamboo reinforcement or bamboo reinforcement net or glass fiber or glass cross or cloth or wire or woven wire Huo Zhong Seats etc. in the top of this sandwich layer and bottom respectively, carry out hot pressing then or cold pressing with gluing.When making secondary operations, can answer on the plate two sides of having made, for example veneer, PLASTIC LAMINATED, glued board, fiberboard, particieboard, gypsum panel, mould molding diamond plate, cement plate, parquet floor face and various decoration papers or the like with various surface decoration materials;
2, the method for manufacturing wood-based plate as claimed in claim 1 is characterized in that said glue is urine aldehyde glue or phenol glue, said hot pressing, and its condition is temperature 120-130 ℃, pressure 5-7kg/cm
2; Temperature when colding pressing is a room temperature, and pressure still is 5-7kg/cm
