Embodiment 1
[0013] 1. The heat-resistant PVC laminate of this embodiment is made of the following raw materials in parts by weight: 100 parts of PVC resin powder (SG-5 resin produced by Shandong Qilu Petrochemical), 4.1 parts of stabilizer (calcium-zinc composite thermally stable agent), lubricant (PE wax) 0.7 parts, filler (1250 mesh calcium carbonate) 15 parts, heat-resistant agent 5 parts.
[0014] The heat-resistant agent is prepared from styrene, oleic acid and acrylonitrile by suspension polymerization. The preparation method of the heat-resistant agent is as follows: add styrene to oleic acid and keep stirring for 2 hours, heat to 88°C, add acrylonitrile several times, keep stirring at 88°C for 2 hours; then cool to below 40°C, wash, It can be filtered and dried; the volume ratio of oleic acid to styrene is 4:1; the total mass of acrylonitrile added is 8% of the mass of styrene.
[0015] 2. The preparation method of the heat-resistant PVC laminate is as follows: add all the raw ma...
Embodiment 2
[0017] 1. The heat-resistant PVC laminate of the present embodiment is made of the following raw materials in parts by weight: 100 parts of PVC resin powder (SG-5 resin produced by Shandong Qilu Petrochemical Co., Ltd.), stabilizer (calcium-zinc composite heat stabilizer) 3.6 parts, 0.6 parts of lubricant (PE wax), 14 parts of filler (1250 mesh calcium carbonate), 10 parts of heat-resistant agent.
[0018] The heat-resistant agent is prepared from styrene, oleic acid and acrylonitrile by suspension polymerization. The preparation method of the heat-resistant agent is: add styrene to oleic acid and continue to stir for 30 minutes, heat to 88°C, add acrylonitrile several times, keep stirring at 86°C for 1 hour; then cool to below 40°C, wash, It can be filtered and dried; the volume ratio of oleic acid to styrene is 3:1; the total mass of acrylonitrile added is 5% of the mass of styrene.
