Green environmental protection low-temperature impact-resistant PVC-U electrical casing

Abstract

The invention discloses a green environmental protection low-temperature impact-resistant PVC-U electrical casing. The green environmental protection low-temperature impact-resistant PVC-U electricalcasing comprises the following raw materials in parts by weight: 90-110 parts of PVC resin, 4-6 parts of calcium-zinc composite stabilizer, 6-10 parts of AMB resin, 0.1-1 part of PE wax, 0.1-1 part ofstearic acid, 10-30 parts of inorganic filler, 2-4 parts of processing modifying aid and 2-3 parts of titanium dioxide. As the new calcium-zinc stabilizer replaces the traditional lead salt stabilizing system and the toughening modified ternary copolymer resin (AMB resin) is added, the low-temperature performance is obviously improved compared with the traditional PVC electrical casing, the product still has good toughness at minus 15 DEG C, and meets the construction requirements of the cold market place in the north; compared with the traditional CPE toughening system, the AMB resin dispersed sea-island energy absorption toughening system has obvious advantages, the sea-island energy absorption toughening system can maintain good rigidity at higher temperature. The products are environmental protection green building materials, more in line with modern home decoration requirements.

Description

technical field

[0001] The invention relates to the technical field of plastic pipes, in particular to a green, environment-friendly, low-temperature impact-resistant PVC-U electrical bushing. Background technique

[0002] PVC-U pipe is also called hard polyvinyl chloride pipe. PVC-U electrical casing is a kind of sheathing pipe with strong corrosion resistance and easy installation and use. PVC-U electrical conduit pipes and pipe fittings are threading pipes and pipe fittings made of polyvinyl chloride resin as the main raw material, added with special additives, and processed by extrusion and injection molding.

[0003] PVC-U pipe is developing rapidly as a plastic product for construction, especially in some developed countries, its total consumption has accounted for 80% to 90% of plastic pipes, and PVC-U pipes have been used as threading pipes for more than 90% of the buildings. . In recent years, China's construction threading pipes have also adopted PVC hard pipes a...
