Wood plastic composite be using timber or various lignocellulose fibers as stock, by from plastics with different
A kind of compound advanced composite material (ACM) formed of approach.The constituent of wood plastic composite is divided into matrix, filler and added
Plus the part of agent three.The more matrixes of application are polypropylene, polyvinyl chloride, polystyrene, PET at present
And polyethylene, wherein polyethylene based composition is most widely used.
Wood plastic composite has the advantage of both string and high polymer material, acid and alkali-resistance, salt water resistance, ultraviolet resistance concurrently
Property 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 wood
Moulding material turns into a kind of green material of great development prospect.Wood-plastic material has been widely used for building trade, automobile
Industry, logistics transportation, indoor decoration and military industry etc., with good application development.But, wood plastic composite is still deposited
In 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 limited
The application of wood plastic composite is made, the development to wood plastic composite brings larger obstruction.
Chinese patent CN201610650144.0 discloses a kind of polyethylene wood-plastic dalle and its manufacture method, and its is big
Body step is as follows：(1) crushed after the wooden shell of bar denier is dried with Jing Yin pulverizer, the wooden shell coarse powder of bar denier is obtained after sieving；(2) by bar
Denier wood shell coarse powder is crushed with the super prestige of micronizer, and the wooden shell fine powder of bar denier is obtained after sieving；(3) by the wooden shell fine powder hydrogen-oxygen of bar denier
Change filtering, washing after sodium solution processing, dry, obtain the wooden shell fine powder of alkali process bar denier；(4) the wooden shell fine powder of alkali process bar denier is led to
Cross octadecyl alcolol and be modified processing, obtain being modified the wooden shell fine powder of bar denier；(5) PE and each auxiliary agent are stirred into compound, will be mixed
Material is closed by extrusion, mixing granulation, drying, injection molding, polyethylene wood-plastic dalle is obtained.The poly- second that the invention is produced
Alkene wood-plastic decorative board material has stronger antioxygenic property, but still has much room for improvement in terms of its anti-corrosive properties and antibacterial surface.
