Abstract

The invention relates to a cold-resistant and pressure-resistant PVC (polyvinyl chloride) profiled bar which comprises a PVC base material, a processing reinforcing agent and a PVC modifying agent. The content of the PVC base material ranges from 60% to 85%, the content of the processing reinforcing agent ranges from 3% to 7%, and the content of the PVC modifying agent ranges from 10% to 35%. The PVC base material is composed of, by weight, 100 parts of polyvinyl chloride, 2 parts of antioxidants, 15-20 parts of flame retardants, 2 parts of heat stabilizers, 5-7 parts of epoxidized soybean oil, 0.5 part of zinc stearate, 0.5 part of stearic acid, 2 parts of processing agents and 10 parts of titanium dioxide. The PVC modifying agent is composed of, by weight, 2-5 parts of ethylene-ethylene vinyl acetate copolymer, 2.5-4 parts of di-n octyl phthalate, 4 parts of cyclohexanone and 5 parts of dimethylbenzene. The cold resistance and the pressure resistance of the cold-resistant and pressure-resistant PVC profiled bar are greatly improved, the preparation process is simple, and materials are easily obtained.

Description

technical field [0001] The invention relates to a PVC profiled material, in particular to a cold-resistant and pressure-resistant PVC profiled material. Background technique [0002] With the continuous advancement of science and technology, the appearance of the city is changing with each passing day, and the urban construction is getting faster and faster, so the application of PVC profiles is becoming more and more extensive. However, the current PVC profiles are heavy, low in strength, poor in cold resistance, and easily shattered. In view of the above shortcomings of PVC profiles, there are also many technologies to solve them. Generally, an additional layer is wrapped outside the PVC profile or other materials are implanted inside the PVC profile. However, this will increase the quality of PVC and prepare The process is complicated and causes a lot of waste. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcom...
