Embodiment 1-7
[0035] In terms of parts by weight, the composition of the new PVC biomass foamed profiles of Examples 1-7 of the present invention is as follows according to the serial number 1-7:
[0036] Table 1
[0037]
Embodiment 1-3
[0038] Embodiment 1-3 The technique of producing novel PVC biomass foamed profiles is as follows:
[0039] Step 1. Put the ingredients in the table into a high-speed mixer and mix them thoroughly at high speed until the temperature reaches 110-120°C. Then transfer the mixture from the high-speed mixer to a low-speed cold mixing pot, and lower the temperature to 40-60°C to obtain a mixed material;
[0040] Step 2, kneading and extruding the mixture in a counter-rotating conical twin-screw extruder;
[0041] Step 3, pass the extruded material through the heating mold (the temperature of the heating mold is 165-180°C), and then pump negative pressure to cool and shape it;
[0042] Step 4, the shaped and cooled material is drawn and cut into products of a certain size by the auxiliary machine. The working parameters of the counter-rotating conical twin-screw extruder in this embodiment are as follows: the processing temperature is 156°C in the first zone, 165°C in the second zone,...
Embodiment 4-7
[0047] Embodiment 4-7 The technique of producing novel PVC biomass foamed profiles is as follows:
[0048] Step 1: Put the ingredients listed in the table into the high-speed mixer and mix them thoroughly at high speed until the temperature reaches 110-120°C, then transfer the mixture from the high-speed mixer to a low-speed cold mixing pot, and lower the temperature to 40-60°C to obtain a mixture material;
[0049] Step 2, kneading and extruding the mixture in a counter-rotating conical twin-screw extruder;
[0050] Step 3, pass the extruded material through the heated mold and then pump negative pressure to cool and shape it;
[0051] Step 4, the shaped and cooled material is drawn and cut into products of a certain size by the auxiliary machine. The process parameters of the counter-rotating conical twin-screw extruder in this example are as follows: the processing temperature is 156°C in the first zone, 165°C in the second zone, 175°C in the third zone, 180°C in the four...
