Embodiment 1
[0015] Embodiment 1, a plastic lignified board, the weight ratio of its components is:
[0016] Polyethylene 60%
[0017] Bamboo Fiber 18%
[0019] Talc 2%
[0020] Azodicarbonamide 2%
[0021] Paraffin 1%
[0022] Chlorinated Polyethylene 11%
[0024] Dioctyl phthalate 1%
[0025] The preparation method is as follows: 1. Firstly, the plant fiber is dehydrated and finely powdered by microwave, and the moisture content is controlled to 0.5%, and the plastic is subjected to conventional pulverization and drying treatment; 2. The components are uniformly mixed in a high-speed mixer according to the above ratio; 3. Then use the extruder to extrude and cool and granulate; 4. Finally enter the screw extruder for extrusion molding, the screw compression ratio is 3.5, carry out shaping, cooling, pulling, curling and cutting to obtain the finished product. The temperature of the feeding section and the extrusion section a...
