Description
Technical field
The present invention relates to wood plastic composite technical field, particularly relate to a kind of low-shrinkage pvc base wood-plastic composite material.
Background technology
As far back as last century, the forties people just find paracril and pvc and are studied by technology, paracril has certain polarity, with the solubility parameter of pvc closely, they are amorphous polymers, there is good consistency between the two, therefore usual that they are blended, obtained alloy material has excellent weathering resistance, solvent resistance and good mechanical strength and processing characteristics, is widely used in the fields such as sealing member, electric wire and cable jacket, oil pipe.The alloy material of paracril and polyvinyl chloride is divided into cross-linking type and non-crosslinked type, and the alloy of cross-linking type is insoluble not to be melted, and is difficult to regeneration, causes severe contamination to environment, although and noncrosslinking alloy processing characteristics is better, mechanical property is undesirable.
China is the country that a timber does not enrich, and underproducely causes the demand that can not meet market.Enhancing along with environmental consciousness and the protection to trees, wood plastic composite swarms into the visual field of people gradually, and Wood-plastic material is that one wood powder, xylon or other vegetable fibre fill thermoplastic polymer composite material, has the advantage of timber and plastics concurrently.But existing Wood-plastic material is also difficult to the performance requriements meeting market, and its erosion-resisting characteristics is poor, and especially shock strength sharply declines along with the increase of wood powder content, is difficult to the requirement meeting premium quality product.The polarity of wood powder is very strong, and the consistency between it and thermoplastics is poor, have impact on the mechanical property of matrix material greatly.Kaolin has obtained fine application as a kind of important reinforcing filler or functional filler in plastics and various rubber materials.On the one hand, kaolin output is large, price is low, with polymer-based carbon volume recombination, can significantly reduce plastics cost, on the other hand, kaolinic interpolation, the thermostability of polymer composites, hardness, rigidity can be improved and give material some special physicals, but the raw ore kaolin of directly exploitation at present, and particle size is little, surface energy is high, easy reunion, surface is containing hydrophilic hydroxy group and oxy radical, totally different with macromolecular material interface, poor compatibility, is difficult to dispersed.Therefore need to carry out modification to the interface of wood powder and plastics, to improve the consistency between them, and will process kaolin surface, improve the poor compatibility with macromolecular material interface, make the performance of dispersed raising matrix material.
Summary of the invention
