The composite board product has compression strength of 22-36 MPa, bending strength of 15-28 MPa, bending modulus of 450-980 MPa, breaking elongation of 80-300 %, oxygen index not lower than 25 and use temperature range of -20 deg.c to +55 deg.c, and is mildew-proof, antiageing, wear resistant, corrosion resistant, hydrophobic and smooth. When used as building formwork, the composite board may be used for over 50 times.

Description

Solid waste mold pressing composite algorithm prepares novel building sheet material
Technical field
The invention belongs to solid waste mold pressing composite algorithm and prepare the production method of novel building sheet material.
Background technology
China is the country of a forest reserves poorness, and a large amount of wood chips is arranged every year, and sawdust and wood powder can not get rationally utilizing or going out of use; And flyash and waste or used plastics are the discarded objects of serious environment pollution.Make full use of these solid waste exploitation high value added products, pollute reducing, turn waste into wealth, resource regeneration is that a resources circulation with obvious economic benefit and environmental benefit is utilized engineering again.
Chinese patent " 01119861 " and " 02160123 " disclose the invention that is entitled as " a kind of plastic-wood material construction formwork and preparation method thereof " and " a kind of wood plastic composite and its production and application " respectively.What these two patents were used is: 1. only use pure PP or modified waste plastics PP.Do not adopt other waste or used plastics; 2. used wood powder is long and the processing of its water content all had strict requirement from the particle diameter to the fiber, thereby making full use of of wood powder is restricted; 3. do not use relevant auxiliary agents such as anti-illumination, shock resistance, mildew-resistant, so these performances of goods are difficult to guarantee; 4. do not relate to utilization of coal ash; 5. the moulding way of goods can not guarantee the size typing of wood-plastic products; 6. wood materials needs to handle through special or natural drying and dewatering.
Summary of the invention
The purpose of this invention is to provide the production method that a kind of solid waste mold pressing composite algorithm prepares novel building sheet material.
The present invention passes through to add auxiliary agent with major ingredient: surface conditioning agent, impact modifier, coupling agent, age resistor, plasticizing agent, mould inhibitor, stabilizing agent, fire retardant, the cooperative effect of utilization major ingredient and auxiliary agent in the kneading process of plasticating and online reaction processing, improve caking property between the major ingredient two-phase interface and alternate compatibility and flyash in plastics, wood powder dispersed uniform in plastics, thereby reached increase-volume, plasticising, toughness reinforcing and improve the purpose of goods mechanical properties.
Solid waste major ingredient of the present invention is: the timber leftover bits and pieces wood powder, the wood fragments that need not to handle through special oven dry are considered to be worth doing and sawdust; Waste or used plastics polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), polystyrene (PS) and ABS through pulverizing, granulation; Thermal power plant's electrostatic precipitation flyash need not screen with preceding.
The main processes of its goods is: with the kneading of plasticating of wood powder, wood fragments bits and sawdust and waste or used plastics, make wooden plastic compound, as one of intermediate; Another intermediate is: with the kneading of plasticating of waste or used plastics and flyash, make and mould grey compound, adopting the compound way of mold pressing to make the intermediate layer then is that Wood-plastic material two is outer for moulding the NEW TYPE OF COMPOSITE sheet material of putty material.
The concrete proportioning (parts by weight) of goods is: with 0.8~2 part of 30~50 parts in flyash and silane coupler, mix at a high speed down at 70~90 ℃ and to stir 10 minutes; With 100 parts of the waste or used plastics of granulation and 1~3 part of ethylene/acetic acid ethyl ester, 0.5~2 part of anion surfactant, 0.5~2 part of stearic acid, 1~4 part in paraffin, (1010) 0.2~0.6 parts in antioxidant, 2~6 parts of antimony oxide and decabromodiphenyl oxides, 0.1~0.4 part of zinc oxide and tris phosphite, 2~5 parts of carbon blacks, 0.1~0.2 part of dibasic lead phosphite, 1~2 part of lead sulfate tribasic, 0.2~1 part of barium stearate, mix at a high speed under 80~100 ℃ of conditions stir 10 minutes after, this material is mixed with after treatment flyash, under 110~200 ℃ of conditions, plasticate and mediated 20 minutes, as one of intermediate; With 20~80 parts in wood powder or wood fragments bits or sawdust, 80~20 parts of waste or used plastics of granulation and acrylate are 0.5~2 part, 0.5~2 part of dioctyl phthalate, 0.5~3 part of stearic acid, dibasic lead phosphite 0.1~0.1 5 part, 1~1.5 part of lead sulfate tribasic, 0.6~1 part of barium stearate, 2~5 parts in paraffin, 0.3~1 part of pentachlorophenol, under 110~200 ℃ of conditions, plasticate and mediated 30 minutes, reach the moisture of removing in the wood materials so that well mediate, as another intermediate with moulding wood; Then this material is adopted the mold pressing complex method, in mould, feed high-temperature steam, under the condition of 110~200 ℃, 250~400 tons pressure, kept 15-25 minute, the cooling back demoulding, it is outer for moulding the NEW TYPE OF COMPOSITE sheet material of putty material to make the intermediate layer and be Wood-plastic material two, because these template two skins are the putty materials of moulding based on plastics, dimensional stability is good and have a better hardness; And force Wood-plastic material to be clipped in the middle, thereby avoided common wood plastic product be difficult for to guarantee that size typing and surface are dashed the disadvantage that is prone to depression after bumping.
The prepared product compressive strength of the present invention can reach 22~36MPa, flexural strength 15~28MPa, composite bending modulus 450~980MPa, elongation at break 80~300%, oxygen index (OI) 〉=25, serviceability temperature is-20 ℃~55 ℃, and mildew-resistant, anti-aging, anti-illumination, wear resistant corrosion resistant, hydrophobic, finish are good; Can use repeatedly more than 50 times as construction formwork.
