Preparation Method.
Background technology
With the rapid development of plastics industry, the application of plastic products is also more and more, has penetrated into each of national economy
In a field and people's daily life.Then not degradable in view of its unique property stabilization, lead to the waste after its use
Accumulation seriously affected the environment around the people, referred to as " white pollution ".Wood plastic composite be by biomass fiber and
Plastics and the mixing of other additives a kind of new material made of extrusion or compression molding.Wood plastic composite set wood
The advantages of material and plastics, has carried out good recycling to waste resource, and has reduced the use of timber, alleviates to a certain degree
The anxiety of wood supply is mainly used for building, communal facility and automotive field, such as makees bed board, fence, decoration.
That there are intensity is low for traditional wood plastic composite, water proofing property is poor and binding force between plastics and timber is weak etc. lacks
It falls into, causes its application range of its manufactured product very narrow.However in order to improve this problem, researcher attempts using even
Join agent to solve the binding force between plastics and timber, but since there are pollutions for coupling agent, for interior decoration then
Easy do harm to huamn body, therefore the modification material be badly in need of a kind of pollution-free substitute and combine other high intensity, water proofing property excellent
Expect to improve the comprehensive performance of the composite material.
