Description
Technical field
The present invention relates to a kind ofly like wooden bamboo fibers die composite material, relate to or rather that a kind of environmental protection, sound insulation, heat insulation, good airproof performance, intensity are high, the modified composite material of better tolerance.
Background technology
A large amount of denudations is unfavorable for the human society harmonious development, in order to make full use of resource as the effective means of protecting environment, cutting down the consumption of energy, to mould Dai Mu, to show one's talent with the thinking of moulding Dai Gang.Yet today of 21 century, the application of wood-plastic products is still very little, seldom sees in the real life.Even in some developed country, this material is being made aspects such as wood-plastic door window, railroad ties, building template, car door shield, car inner piece and decorations, also just is in beginning and starting stage.The application of wood-plastic products, the scientific research technology of awaiting further deeply and perfect, but in 21st century, will be developed rapidly, this has become the common recognition of department such as environmental protection, building, government and scientific circles.
Recent years, the research of wooden mold tool composite technology has become the focus of domestic and international research of the same trade.Yet existing wood-plastic products performance is on the low side, unstable product quality.The starting material that meet the environmental protection source are fewer and feweri, expect always on the industry that mechanical property is good, and material source is cheap, and outward appearance and processing characteristics more approach the appearance of the wood-plastic products of timber.
Summary of the invention
The object of the present invention is to provide a kind of HS, corrosion-resistant, good weatherability, outward appearance and processing characteristics more approach the wooden mold tool matrix material of timber.
The present invention realizes above-mentioned purpose through following compsn, and said composition comprises: bamboo fibers 55%-70%, wood powder: 15%-55%, new LDPE (film grade) 22%, solubilizing agent 2%, lubricant 2.5%, thermoplastics 1.5-2.5%, 700 order superfine talcum powders 3%, vinylbenzene and methyl acrylate mix monomer: 1%, be selected from any plastics among PVC, PP, the PE: dibasic lead phosphite 2.5%: dibasic lead stearate 0.2%: lead stearate 0.1%: soft ester acid calcium 0.1%; 1.0%, lime carbonate: macromolecule wax 1%: 0.1%, the melamine resin 3%.
One or more of thermoplastics: Vilaterm, Vestolen PP 7052, polybutylenes, SE, PS, third rare, the nitrile-butadiene-styrene terpolymer.
Except that above-mentioned component, can also add silane coupling agent 1-2.5%; Titanate coupling agent 1-2.5%.
Except that above-mentioned component, can also add lead sulfate tribasic:＞0.5%, the resin compatible agent; Paraffin:＞1%, OPE:＞1.0%.
The preparation method of described bamboo fibers is: waste and old bamboo tankage are worn into 30-80 purpose powder through crusher pulverizing, grinding machine, make the bamboo powder; The bamboo powder is dried to water ratio in the mixing machine that the band thermal oil heats up weight concentration adopts the described bamboo fibers of anoxic bar can adopt the stalk of farm crop corn, soya bean, Chinese sorghum or paddy rice to substitute less than 2%.
The present invention has very high intensity and bending resistance and shock resistance through the matrix material of modification; The outward appearance of material of the present invention is similar to timber in addition, and can use plane, saw, and the mode of converted timbers such as cutter is processed; Thereby make this matrix material have heat insulation, sound insulation, good weatherability; Do not corrode, advantages such as environmental stress resistance have fundamentally solved the low shortcoming of product mechanical strength of wooden molding technology before; Wherein resistance to impact shock significantly improve the fragility problem that efficiently solves the article that produce originally, make wood mould compounding technology and be converted into actual high-performance commodity.And this wood plastic composite production energy consumption is low, all recyclings of waste material that production process produces, and non-environmental-pollution is typical Green Product.
Embodiment
Through embodiment the present invention is described further below, but protection scheme of the present invention is not limited to following examples.
