Embodiment 1
[0020] Add 60 parts of polyvinyl chloride resin, 15 parts of activated wood powder, 40 parts of activated light calcium, and 40 parts of recycled building formwork into a high-mixing pot and heat it to 90°C, then add 3.2 parts of stabilizer, 10 parts of foam regulator, Add 0.4 parts of AC foaming agent, 0.6 parts of NC foaming agent, 0.3 parts of stearic acid, 0.3 parts of oxidized polyethylene wax, 0.7 parts of internal lubricant G600, 30.3 parts of external lubricant OA, and 5 parts of toughening agent poe into In a hot mixing pot, mix well and heat to 130°C. Then put it into the cold mixing pot for cooling and mixing to 45°C, then put it into the receiving bin and send it to the main machine, plasticize and foam the mixture at 220°C, use two mold temperature controllers to control the mold oil temperature and water temperature at 180 ℃ for skinning. Then adjust the temperature of the shaping table and the chiller to 18°C to shape and cool the extruded material, adjust th...
