Low-volatile environment-friendly polyvinyl chloride (PVC) cable material and manufacturing process thereof

Abstract

The invention provides a low-volatile environment-friendly polyvinyl chloride (PVC) cable material and a preparation method thereof. The PVC cable material includes the following components in part by weight: 80 parts of PVC resin with a polymerization degree of 1,000, 15 to 20 parts of SG4 PVC resin, 10 to 40 parts of di-isononyl-cyclohexane-1,2-dicarboxylate, 20 to 35 parts of polyester plasticizer GX-68, 4 to 6 parts of antimonous oxide, 7 to 9 parts of zinc borate, 10 to 20 parts of fillers, 8 to 12 parts of aluminum hydroxide, 5 to 8 parts of a calcium-zinc heat stabilizer, 0.2 to 0.4 part of antioxidant 1010, 0.4 to 0.6 part of a lubricant, 0.8 to 1.2 parts of processing modifier ACR (acrylic resin), 5 to 8 parts of polyester plasticizer TX-50, 1 to 2 parts of modified silicon dioxide, and 0.2 to 0.5 part of sulfur. The PVC cable material provided by the invention has the low-volatile and low-odor effects under a high-temperature environment, the fogging value reaches 0.44 milligram, high volatility resistance and low product odor are achieved, and both the volume resistivity and aging strength retention of the cable material are improved.

Description

Technical field [0001] The present invention involves environmental protection cables, and especially involves polyvinyl chloride cables and its manufacturing processes. Background technique [0002] As the most common plastic product in life, Polyvinyl chloride (PVC) is widely used in the manufacture of various PVC pipes, PVC plates, PVC films, PVC wallpaper, PVC cable materials, etc., which is the most widely used in the five major plastic plastics. [0003] Polyvinyl chloride cable is composed of PVC resin, plasticizer, stabilizer, fillers, processing modifiers, lubricants and pigments.Among them, the softness of the PVC cable is adjusted by the proportion of plasticizers in the PVC formula. The more plasticizer content, the softer the cable material is.Ordinary cable materials choose some conventional plasticizers to soften PVC. Due to its own characteristics and production technology, the cable materials produced are heavy, pungent, and large amount of smoke.The first -line ...

AI Technical Summary

Problems solved by technology

Ordinary cable materials choose some conventional plasticizers to soften PVC. Due to its own characteristics and production technology, the produced cable materials have a strong smell, are pungent, and have a large amount of smoke, which is harmful to downstream cable production units. Front-line operators caused varying degrees of physical injury

Due to the poor quality of selected plasticizers for some cable materials, problems such as oil leakage and precipitation are caused in the produced cables, which shorten the service life of the products and pollute the environment.
