Abstract

The invention relates to a polyvinylchloride (PVC) modified material. Every unit of the material comprising 100 parts by weight of polyvinylchloride resin comprises, by weight, (A) 1-10 parts of quasi-styrene which is a graft copolymer of rubber or elastomer and alpha-methyl styrene, (B) 5-30 parts of thermoplastic polyurethane, (C) a thermal stabilizer, (D) a plasticizer and (E) an optional auxiliary plasticizer. According to the polyvinylchloride modified material, on a basis that good transparency of polyvinylchloride resin is substantially maintained, the plasticizing temperature is reduced and the cold resistance is improved, such that comprehensive performances of the material are improved. The invention also relates to a method for preparing the polyvinylchloride modified material. The method comprises the steps of melting and kneading all components of the polyvinylchloride modified material. The PVC modified material is transparent and environment-friendly. The plasticizing temperature is greatly reduced, and the material also has good cold resistance. Therefore, the material can be used for preparing transparent environment-friendly PVC soft products used under low-temperature environments.

Description

technical field [0001] The invention relates to a polyvinyl chloride modified material, more specifically to a cold-resistant polyvinyl chloride modified material which is transparent and has a relatively low plasticizing temperature, especially the soft polyvinyl chloride modified material. The invention also relates to the preparation and application of the polyvinyl chloride modified material. technical background [0002] Polyvinyl chloride (PVC) is a general-purpose plastic with excellent comprehensive properties, widely used in all walks of life, and is currently the second largest resin variety after polyethylene (PE). PVC has the advantages of oil resistance, acid and alkali resistance, excellent electrical properties, and good light transmission. PVC soft products refer to PVC products with certain flexibility made by adding plasticizers in the formula. Soft PVC products occupy an important position and are widely used in building decoration materials, artificial ...
