Abstract

The invention provides a nontoxic, anti-heat shrinkable polyvinyl chloride material, comprising the following components in parts by weight: 100 parts of polyvinyl chloride resin, 20-30 parts of filling, 10-60 parts of plasticizer, 1-2 parts of lubricating agent, 2-12 parts of compound stabilizer, 3-10 parts of fire retardant and 10-15 parts of anti-heat shrinkable agent. The invention also provides a manufacturing technology of the nontoxic, anti-heat shrinkable polyvinyl chloride material. The nontoxic compound stabilizer and the anti-heat shrinkable agent are added to the nontoxic, anti-heat shrinkable polyvinyl chloride material, which dramatically improves various thermostabilization performances of the polyvinylchloride material, especially the anti-heat shrinkable performances. The raw material of the invention has low cost and is environment friendly, thus having wide application prospect.

Description

technology technical field [0001] The invention belongs to the technical field of polymer material modification, and specifically relates to a non-toxic, heat-shrinkable polychloride material and a manufacturing process thereof. back scene technology [0002] Polyvinyl chloride (PVC), as one of the general-purpose resins, has the advantages of high strength, corrosion resistance, good insulation, excellent resistance, low price, and wide source of raw materials, and is widely used in construction, electric power, appliances, agriculture, utilities and other industries. In recent years, the world's total demand for PVC is still showing a steady growth trend. Modification can not only endow PVC materials with special properties, but also significantly improve their processing performance and other physical properties. As people have higher and higher requirements for material performance and increasingly detailed requirements for specific functions, almost all PVC products...
