Abstract
The invention discloses an environment-friendly plastic wood composite plate, which comprises the following materials in percentage by taking the weight of the environment-friendly plastic wood composite plate as a standard, 30-78% of mixed waste plastics, 20-68% of mixed wood and 2-7% of grass fiber materials and blend system materials. The preparation method of the environment-friendly plastic wood composite plate comprises the following steps: first, removing impurities of the mixed waste plastics and the mixed wood and grass fiber materials, drying and crushing; then, blending uniformly the crushed mixed waste plastic aggregates, the crushed mixed wood and grass fiber material aggregates and the blend system materials according to the proportion, and pressing the mixture into the environment-friendly plastic wood composite plate at 180-230 DEG C and 2.5-4 MPa; and next, cooling and cutting. The environment-friendly plastic wood composite plate is widely applicable to building templates, logistics boxes, garden landscapes, external wall decoration, wooden trestles, railings, household bathrooms, balconies, kitchenware and the like.
Description
One, technical field
The present invention relates to a kind of environmental protection and mould wood composite board and manufacture method thereof.
Two, background technology
In the applicant's a Chinese patent ZL02226119.2 (open day is on January 29th, 2003), a kind of wood composite board of moulding was described once, the plate body of moulding timber matter structure that it adopts short period of time heating high-pressure fusion to make.This shortcoming of moulding wood composite board is: can only adopt with a kind of waste or used plastics and make raw material, can not adopt PP, PE, PVC and the PET etc. of multiple different melting points to mix plastic waste and agronomic crop fibre material or both and mix and make raw material; Its letter sorting mix plastic waste difficulty, needed expense big, be difficult to carry out, and cost of material is high, can't organize production in enormous quantities; Simultaneously, adopt the thermal pressure machine repeatedly laminated into type, production efficiency is low, manufacturing cost is high.At present, do not see as yet to adopt to mix plastic waste and/or to mix wood-grass fiber and do the environmental protection of raw material and mould wood composite board and manufacture method thereof.
Three, summary of the invention
PP, PE, PVC, the PET etc. that the objective of the invention is to solve different melting points mix plastic waste and/or mix wood-grass fiber and make raw material and make the technical barrier that wood composite board is moulded in environmental protection, provide a kind of environmental protection to mould wood composite board and manufacture method thereof.
The object of the present invention is achieved like this: environmental protection of the present invention is moulded wood composite board and is comprised and mix plastic waste, mix wood-grass fiber material and co-mixing system material, moulding wood composite board weight with environmental protection is standard: mixing plastic waste content is 30～78%, mixing wood-grass fiber material content is 20～68%, and co-mixing system material content is 2～7%.
The plastic waste that mixes wherein is the plastics that useless PP, PE, PVC, PET material mix arbitrarily.
The wood-grass fiber material that mixes wherein is waste wood and/or agronomic crop fibre material.
Component wherein mixes plastic waste, and to contain weight ratio be 40～57%, and mixing the wood-grass fiber material, to contain weight ratio be 40～57%, and it is 3～5% that the co-mixing system material contains weight ratio.
Described environmental protection is moulded the surface of wood composite board and is pasted fabric and/or impregnated paper.
The present invention also proposes the manufacture method that wood composite board is moulded in above-mentioned environmental protection: at first, will mix plastic waste, mix the wood-grass fiber material and remove impurity, drying, pulverizing; Then, will mix the plastic waste particle, mix wood-grass fiber material particle and co-mixing system material, evenly mixed by described proportioning, under 180～230 ℃ of temperature, pressure 2.5～4 MPas, be pressed into environmental protection and mould wood composite board; Then, cooling, cutting.
Can mould the plastic waste that mixes of component in the wood composite board as environmental protection of the present invention, at first, non-plastics such as wherein sand, stone, metal, earth be removed; Then, dry (water ratio is less than 4%), pulverizing are particle or powder or small pieces, preferably make section or particle.
Can mix the wood-grass fiber material as what component in the wood composite board was moulded in environmental protection of the present invention, at first, non-plastics such as wherein sand, stone, metal, earth be removed; Then, dry (water ratio is less than 4%), pulverizing are particle or powder or particle, and preferably mixing the wood-grass fiber material is waste wood, branch, wood chip, rice bar, straw, corn cob, husk, wheat husk or its adulterant.
Can mould phthalic acid ester coupling agent MPZ-105 or polyacrylate MAPE and compound rare-earth compound S R-" 1+2 " of increase thermostability and processing modified chlorinatedpolyethylene or the vinyl chloride-vinyl acetate resin of co-mixing system material for increasing consistency of component in the wood composite board as environmental protection of the present invention.Preferably use PC-g-PS increase-volume PC/PS co-mixing system material or PC/PET/PE-g-MAM co-mixing system material, can obviously improve consistency and the product performance of co-mixing system material.
Also can add other components though wood composite board is moulded in environmental protection of the present invention,, the preferred environmental protection of the present invention mould wood composite board only by mix plastic waste, it two is formed to mix wood-grass fiber material and co-mixing system material or three.If add other components, then mould the component that to add in the wood composite board in preferred environmental protection and only comprise on a small quantity, for example Wei Liang softening agent or binding agent.
The raw material pulverizing pulverizer of wood composite board is moulded in environmental protection of the present invention, the preferred granulation production line that adopts, preferred adopt high-speed mixer will mix plastic waste, mix the wood-grass fiber material and its component of two of these threes of co-mixing system material is fully mixed, preferred plastic wood sheet production line or the employing thermocompressor is made up of extrusion machine, rolling press, tractor and the sheet shears of band slit head of adopting is laminated into type.
After adopting such scheme, because employing mixes plastic waste, mixes the wood-grass fiber material, can adopt the agronomic crop fibre material, make more extensive, the more environmental protection of raw material sources, thereby save a large amount of letter sorting human and material resources, the agronomic crop fibre material that reduces plastic waste greatly and all be used to burn in the past infringement that atmospheric environment is produced, good social benefit and economic benefit are arranged.
Environmental protection of the present invention is moulded the wood composite board manufacture method and is had production technique advanced person, raw material abundance, advantage that production cost is low, and the product of manufacturing is durable, waterproof, insect protected, anticorrosion, anti-aging, no warpage, and color tunable, can cycling and reutilization.
Very reclaiming of wood composite board is moulded in environmental protection of the present invention, and it becomes real environmentfriendly products, is a kind of comparatively desirable timber equivalent material.It can be widely used in building template, box for material circulation, garden landscape, decoration of exterior wall, wooden footway, railing, family expenses bathroom, balcony and kitchen tools etc.
