Abstract
The wooden plastics as a composite used for building, furniture, package, decoration and making mechanical parts is made up from waste plastics, wood or bamboo bits and additive through moulding at proper temp and pressure. A cooling apparatus is designed for mould.
Description
The present invention relates to the matrix material of a kind of plastics and wood fibre, particularly utilize the processing of waste or used plastics and useless bamboo and wood bits to mould the processing method that wood closes the matter material.
Processing fent and recovery waste or used plastics in order to make full use of the bamboo and wood material reduce environmental pollution, turn waste into wealth, and the someone has proposed above-mentioned two kinds of materials are combined into the technical scheme of NEW TYPE OF COMPOSITE substitute materials for wood.As application number is the Chinese patent application of 89107953.X, the production technique of a kind of " plastic waste and made from composite material of plant fiber " is disclosed, the matrix material that makes by this explained hereafter, the advantage that integrates timber and plastics, both had a processing characteristics such as saw, plane, nail, brill of timber, resemble plastic plasticity again, and physicals such as its hardness, intensity, toughness, water-fast, corrosion resistant, wear resistance and insulativity all is better than natural timber.But the shortcoming that this production technique exists is that " the proportioning raw materials scope is less, and production efficiency is low, is unsuitable for serialization scale operation, and product compression molding instability is yielding.
It is big to the purpose of this invention is to provide a kind of proportioning raw materials scope, can large-scale continuous production mould the high efficiency producing process that wood closes the matter material, and formed product is stable, indeformable.
Main points of the present invention are: the optimal components ratio scope of having found out thermoplastics raw material and wood fibre: thermoplastics: wood fibre=1: 1-5 (weight ratio); Its production technique is: with above-mentioned two kinds of raw materials cleaning, drying, then the thermoplastics raw material is processed into the fritter of diameter less than 10mm respectively, lignocellulose raw material is ground into 20-120 purpose particle; Measure two kinds of raw materials by the design proportioning, the requirement according to variant production adds a certain amount of various additive again, and thorough mixing is even; Compound is added injection moulding machine or rolling press, under 160-200 ℃ temperature, directly be injection molded into product or exhibition is pressed into sheet material, or compound is added extrusion machine earlier, be heated to 160-200 ℃, squeeze out grog, send into mould immediately, at 40-300Kg/cm with refrigerating unit
2Compression molding material under the pressure.
Production technique of the present invention is simple, and is easy to operate, because product promptly is with the mould cooling in mold process, the product depanning is fast, and the production efficiency height is suitable for the serialization scale production, and the dawn formed product is stable,, indeformable.This technical recipe is flexible in addition, as long as regulate the proportioning and different additives of two kinds of main raw materials, can produce sheet material, section bar or the product of various characteristics, can be widely used as the starting material of building, furniture, packing, decoration etc., or directly be molded into the component of machine of complex structure, product super quality and competitive price.
Embodiment 1: cleaning, exsiccant bamboo and wood material processing fent with weight half and half are ground into 20 purpose particles with pulverizer; Other after cleaning, drying, is processed into the fritter of diameter less than 10mm with waste polyethylene; Press vinyon: the proportion ingredient of bamboo wood chip=1: 4 (weight ratio), and add an amount of antiaging agent and fire retardant, thorough mixing is even; Compound is added extrusion machine, and the Heating temperature of regulating the control extrusion machine squeezes out thick grog at 175 ± 5 ℃; Send into the mould that has chilled water unit, promptly offer cooling-water duct on the mold wall or the mould of jacketed type cyclic water tank is set, at 40Kg/cm
2Mold pressing is 3 minutes under the pressure, and it is smooth then to make any surface finish, and the lignin plastics sheet material of 600 * 380 * 10mm that can paint, and its hardness reaches 17 ° of Bu Shi.This sheet material is particularly suitable for making audio amplifier.
Embodiment 2: will clean exsiccant bamboo and wood tankage separated pulverizing and become 60 purpose particles, and be respectively 40% and 60% mixed by bamboo and wood; Thermoplastics adopts waste polyethylene and polypropylene half and half, is processed into the fritter of diameter less than 10mm; Press thermoplastics: bamboo wood chip=1: 2 (weight ratio) batching, add an amount of antiaging agent, fire retardant, water repellent agent simultaneously, also can add certain pigment as required, fully evenly mixed; Blended stock is added rolling press, and the control Heating temperature is at 170 ± 5 ℃, rolls 1000 * 1000 * 4mm sheet material.This lignin plastics timber intensity height, good toughness, nonhygroscopic, without putrefaction is not damaged by worms, and certain flame retardant properties is arranged, and can follow closely, dig, saw, bore.Building decoration, wrapping material can be widely used in, also furniture etc. can be made.
Embodiment 3: proportioning raw materials is, diameter is less than the polypropylene of 10mm: 100 purpose wood chips=1: 1 (weight ratio), add an amount of antiaging agent and fire retardant again, and fully mixed; Compound is added injection moulding machine, at 180 ± 5 ℃ of temperature, pressure 50Kg/cm
2Directly be injection molded into textile manufacturing machine parts-quilling tube internal lobe down.These parts are because global formation, the internal lobe intensity height that is processed into batten originally, and assembling, running are reliable and stable, improved work-ing life greatly, and any surface finish, attractive in appearance.
