Description

Wood and plastic composite preparation method for material
Technical field
The present invention relates to a kind of polymer composite preparation method, especially a kind of preparation side of wood plastic composite Method.
Background technology
Wood-plastic composite panel is a kind of composite material being combined by wood powder and resin matrix, can realize the scale of wood powder Change and utilizes.But wood powder and resin matrix are difficult to compatible, another aspect, a large amount of moisture content of wood powder, but also wood powder and resin matrix It is difficult to compound so that wood-plastic composite panel prepares relatively difficult.
Invention content
In view of the deficiencies of the prior art, the present invention proposes a kind of defects that can overcome wood powder and resin matrix compatibility, promote The wood and plastic composite preparation method for material compound into wood powder and resin matrix.
The present invention is achieved through the following technical solutions technical goal.
Wood and plastic composite preparation method for material, thes improvement is that：It includes the following steps：
1）Wood powder is mixed 15-18 minutes for 1700 ~ 2300 revs/min by mass parts through high speed with nano oxidized calcium powder；
2）1700 ~ 2300 revs/min of high speed mixes 6-8 minutes after silane and titanate coupling agent is added by mass parts；
3）It is poly- by mass parts addition polyvinyl chloride, light active calcium carbonate, azodicarbonamide, organotin, polyethylene wax, chlorination Ethylene, nano zine oxide, silicone processing aid, inorganic nano-particle mix 15 ~ 25 minutes for 1700 ~ 2300 revs/min through high speed Afterwards, then after the mixing 7 ~ 12 minutes of 300 ~ 500 revs/min of low speed, premix is obtained；
4）The premix is shaped through conical double screw extruder foam shaping by extrusion, 0 ~ 15 DEG C of recirculated water rapid cooling, is led Draw, cut.
Compared with prior art, the present invention having the positive effect that：
1, add nano calcium oxide, when lime powder and wood powder carry out mixed at high speed, on the one hand utilize lime powder compared with Strong water absorption character absorbs the moisture in wood powder；On the other hand, calcium hydroxide is generated after calcium oxide water suction, it is special using its alkalinity Property, the dissolvings such as the colloid on wood powder surface can be conducive to improve the compatibility and interface cohesion between wood powder and resin matrix Power.
2, silane and titanate coupling agent is added, surface modification is carried out to wood powder, is solved between wood powder and resin matrix The problem of interface compatibility difference and bad dispersibility in resin matrix.
Specific implementation mode
With reference to embodiment, the invention will be further described.
Wood and plastic composite preparation method for material comprising following steps：
1）Wood powder is mixed 15-18 minutes for 1700 ~ 2300 revs/min by mass parts through high speed with nano oxidized calcium powder；
2）1700 ~ 2300 revs/min of high speed mixes 6-8 minutes after silane and titanate coupling agent is added by mass parts；
3）It is poly- by mass parts addition polyvinyl chloride, light active calcium carbonate, azodicarbonamide, organotin, polyethylene wax, chlorination Ethylene, nano zine oxide, silicone processing aid, inorganic nano-particle mix 15 ~ 25 minutes for 1700 ~ 2300 revs/min through high speed Afterwards, then after the mixing 7 ~ 12 minutes of 300 ~ 500 revs/min of low speed, premix is obtained；
4）The premix is shaped through conical double screw extruder foam shaping by extrusion, 0 ~ 15 DEG C of recirculated water rapid cooling, is led Draw, cut.
