Abstract
The invention relates to a pultruded wood glass fabric fiber reinforce plastic tube and a molding method thereof. The molding method comprises the steps of: processing wooden material into wood slats with limited length; matching the wood slats with glass fiber yarn weaving or non-weaving to prepare wood glass cloth; matching the wood glass cloth with glass fiber yarn, felt, fabric and other reinforcing materials according to the need, and carrying out the working procedures such as resin preimpregnation, presetting, solidification molding, drawing, cutting and the like; and obtaining the wood glass cloth fiber reinforce plastic linear tube products which have the shapes being the same as those of moulds and have various wall thicknesses by pultrusion. The pultruded wood glass fabric fiber reinforce plastic tube can be widely applied to multiple occasions such as a water feeding pipe, a sewer pipe, an oil delivery pipe, etc.
Description
The invention belongs to the fiber hybrid composite production technical field, particularly wood fibre bar (wood is slightd bar or wood chip or the like) and glass fibre etc. are weaved or the non-woven wood glass fabric that fits in strengthens the thermosetting resin pultrusion and makes various prismatic Wood-glass fabric glass fiber reinforced plastics pipes and forming method.
At present, the pultrude process of known fibre glass roving is a kind of method of continuous producd fibers reinforced plastic section bar.It is the non-twist fibre glass roving on the creel to be carried out resin with other continuous reinforcing material, surface of polyester felt etc. soak achievement, then by keeping shaper, the shaping die of definite shape, and make it in mould, be pulled continuous depanning behind the solidifying, through cutting off a kind of automatic production process that can obtain the glass fibre reinforced plastics pultrusion product.Various glass fibre reinforced plastics pultrusion product performance are good, have wide range of applications, but cost are too high, and the application scale is not very big.The densification of hard miscellaneous tree equipment structure, resistance to compression, tension, wear-resisting property are good, and the specific humidity rate that rises is less mutually with other vegetable fiber except that bamboo material, and its corrosion resistance more is better than other vegetable fibers such as softwood.Timber is renewable raw materials, compares cheaply with other man-made fibre material, produces the usage requirement that various drawing and extruding section bar products can satisfy many occasions with good wood materials.But because timber length, diameter are limited, directly become the flexible distortion forfeiture of plate usability, isolating property, to compare weather resistance poor with plastics or glass fibre reinforced plastics series products under the nature, directly with the compound compatibility performance difference of various fluoropolymer resins or the like multiple reason, make it fail to use on the pultrusion product, therefore a large amount of wood materials fails to bring into play its due effect.Big, the easy-to-rust of weight such as steel pipe, cast iron tube, cement pipe is installed inconvenience now; Plastic tube intensity is low; Glass Steel Tube price height.
In order to overcome the deficiency of short and small or the like the shortcoming of the high and wood materials of existing roving pulling and extruding glass steel tube product price, pultrusion Wood-glass fabric glass fiber reinforced plastics pipe product provided by the invention, following wood glass fabric is selected the Wood-glass cloth that interweaves for use, be called for short Wood-glass cloth, it is little that Wood-glass cloth can not only guarantee to make full use of hard miscellaneous tree material contour projector, the proper property that tensile strength parallel to grain and parallel-to-grain compressive strength are good, and be short and small by glass fibre, the limited long stuff that isolating property is big is weaved or is together non-woven, this satisfies continuously shaped requirement, the isolating property of having eliminated wood materials has formed the complementary intensity of both direction simultaneously with wood materials, this has also just increased horizontal tensile strength and has also eliminated pultrusion Wood-glass cloth Glass Steel Tube product linear direction disadvantage easy to crack.It just had the outward appearance and the performance of glass fibre reinforced plastic material after Wood-glass cloth soaked the achievement resin solidification, permeability with glass fibre reinforced plastics under the situation about needing also can make it to have the outward appearance that manifests wood materials, utilize the coating skin of glass fibre reinforced plastic material to intercept wood materials and air simultaneously, unfavorable and hostile environments such as mould, the contact of material, therefore can be under the prerequisite of the original performance that guarantees wood materials, prolonged working life widely, also be easy to simultaneously by increasing, the content that reduces glass fibre improves, reduce glass fibre reinforced plastics content and control the performance and the price of Wood-glass cloth Glass Steel Tube product, can satisfy the usage requirement of many applications, also be better than glass fibre reinforced plastics as heat insulation and weather resistance etc., the particularly reduction of price can realize large-scale promotion application.
The technical solution adopted for the present invention to solve the technical problems is: at first by designing requirement the Wood-glass cloth that rolls of one or more same sizes of multireel or different size, Weft wood glass fabric, (wide cut is a Wood-glass cloth to wood glass belt, be wood glass belt in a narrow margin) or Wood-glass cloth, Weft wood glass fabric and wood glass belt are placed on the fabric frame together, as required roving is rolled up, glasscloth, other reinforcing material of glass fiber mat or the like is placed to corresponding glass fiber yarn, felt, on the framves such as fabric, draw Wood-glass cloth, wood glass belt, Weft wood glass fabric, fibre glass roving, felt, the various reinforcing materials of fabric or the like are by organiser, as required by the dehumidifying of dehumidifying heater, heating.Enter steeping vat preimpregnation achievement resin, the reinforcing material that preimpregnation is good (Wood-glass cloth, wood glass belt, Weft wood glass fabric, fibre glass roving, felt, fabric or the like) passes pre-setting device, mould or device with the mould pre-setting, it with Wood-glass cloth, wood glass belt, rove, felt, fabric etc. accurately in conjunction with, remove the bubble in unnecessary resin, the eliminating system.Then enter the continuous Wood-glass cloth glass fibre reinforced plastics pultrusion product that the forming and hardening mold heated with multistage heating function is solidified into required sectional shape, this product is deflected from mould under the traction of traction gear, after the cutting device fixed length cutting becomes the Wood-glass cloth glass fibre reinforced plastics pultrusion product of Len req.Pultrusion Wood-glass cloth Glass Steel Tube product can be that the solid wall pipe section bar also can be the pipe profile of interlayer wall.
The invention has the beneficial effects as follows, the various pultrusion Wood-glass cloth Glass Steel Tube products that go out by this processes can enlarge the application area and the application of wood materials widely, can guarantee that wood materials given play to huge usefulness, batten in the Wood-glass cloth has been reduced isolating property by the coating of glass fiber yarn, felt, fabric etc., simultaneously also increased compatibility with fluoropolymer resin by glass fiber yarn, realize can leaning between the batten mechanical connection of glass fiber yarn and resin, this has eliminated batten and the compound segregative disadvantage of polymeric matrix.The content of glass fiber of Wood-glass cloth can be determined according to usage requirement, also reinforcement such as non-twist glass fiber yarn, felt, fabric can be increased in addition simultaneously.Can increase the loss of saving metals resources greatly and reduce delivery and erection etc. with pultrusion Wood-glass cloth Glass Steel Tube alternative metals and cement pipe.
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the broken section structural representation of pultrusion Wood-glass fabric glass fiber reinforced plastics square tube section bar of the present invention.
Fig. 2 is a part pultrusion Wood-glass fabric glass fiber reinforced plastics pipe profile structural representation, wherein:
