Problems solved by technology

[0002] When polyvinyl chloride is processed and applied, especially when processing hard products, the material has poor impact resistance and poor thermal stability, which seriously restricts the mechanical properties of the material and cannot meet the processing and use requirements. Various modifications must be added. agent
Although the addition of modifiers improves the impact resistance of rigid PVC materials to a certain extent, the compatibility of modifiers with PVC is limited, which affects other mechanical properties of rigid PVC materials, such as the weld angle strength of PVC profiles. The range of improvement is limited, and at the same time, expensive modification additives increase the processing cost of PVC profiles, thus restricting the application and promotion of post-processing products

Abstract

The invention relates to a PVC (Poly Vinyl Chloride) profile added with a chloroethylene-acrylate copolymer resin and a preparation method thereof, and belongs to the technical application of the chloroethylene-acrylate copolymer resin in PVC resin processing. According to the invention, the common PVC resin is modified by using the special properties of the chloroethylene-acrylate copolymer resin such as internal plasticization property, excellent processability and tenacity; the processing formulation by weight is as follows: 100 parts of PVC resin, 5-10 parts of chloroethylene-acrylate copolymer resin, 1-5 parts of heat stabilizer, 5-20 parts of filler and 3-6 parts of other additives. In the processing process of the PVC profile, the chloroethylene-acrylate copolymer resin is used for substituting for processing modifiers ACR (Acrylic Rubber) and CPE (Chlorinated Polyethylene), and a specific mixing process is adopted so as to achieve the synergistic effect of the chloroethylene-acrylate copolymer resin with inorganic particles, and consequently, the processing temperature of the PVC profile is reduced and the mechanical properties of the PVC profile are improved.
