A kind of floor PVC base wood-plastic composite materials and preparation method thereofTechnical field
The present invention relates to Wood-plastic material field, more particularly to a kind of floor PVC base wood-plastic composite materials and its preparationMethod.
Background technology
Wood plastic composite is using timber or various lignocellulose fibers as stock, to utilize producing high-molecular educational circlesThe features such as mechanism and filling-modified Material reinforcement are merged in face, is compounded a certain proportion of plastic matrix and is aided with appropriate processing aid,A kind of new material prepared by special processing process.The more plastic matrixs of application are PP, PVC, PS, PET at presentAnd PE, the occupation rate of market of wherein PVC base wood-plastic composite materials has in recent years to be increased rapidly.
Wood plastic composite has the advantage of both string and high polymer material, acid and alkali-resistance, salt water resistance, ultraviolet resistance concurrentlyProperty good, warpage not easy to crack, and easy to process, cheap, satisfactory mechanical property.Wood-plastic material can substitute timber,Poor forest resources can effectively be alleviated, the problem of wood supply is in short supply, simultaneously because string can be degraded so that woodMoulding material turns into a kind of green material of great development prospect.Wood-plastic material has been widely used for building trade, automobileIndustry, logistics transportation, indoor decoration and military industry etc., with good application development.But, wood plastic composite is still depositedIn some defects, the compatibility of such as timber and matrix resin is poor, timber dispersion effect in the thermoplastic of melting is poor,Melt body poor fluidity, technology processing and forming is difficult, degradable in process, easily corruption etc., and these defects are greatly limitedThe application of wood plastic composite is made, the development to wood plastic composite brings larger obstruction.
