Abstract

The invention discloses a flame retardant antiseptic rigid polyvinyl chloride pipe. The pipe is prepared from, by weight, 23-25 parts of thermoplastic polyurethane, 15-20 parts of nitrile rubber, 2-4 parts of epoxidized soybean oil, 3-7 parts of vinyl acetate, 10-15 parts of octyl stannum mercaptide, 2-4 parts of boron nitride, 5-7 parts of 4,4'-sulfo bis(6-tertiary butyl-3-methylphenol), 2-4 parts of based-titanium whiskers, 6-8 parts of aluminum nitride and 100-110 parts of polyvinyl chloride resin. According to the CPVC pipe obtained through the formula, the flame retardance of the finished pipe is effectively improved, the corrosion resistance is good, the impact strength resistance is high, weather resistance and aging resistance are excellent, the cost is low, environmental protection property is good, the performance is stable, and industrial production, popularization and application are promoted.

Description

technical field [0001] The invention relates to a flame-retardant and anti-corrosion hard polyvinyl chloride pipe. Background technique [0002] Plastic pipes are high-tech composite chemical building materials, and chemical building materials are the fourth largest category of new building materials emerging in the contemporary era after steel, wood, and cement. Chemical building materials have made great progress and developed rapidly in our country, especially the widespread use of new environmentally friendly plastic pipes, which has set off a revolution to replace traditional building materials. Plastic pipes are widely used in the fields of building water supply and drainage, urban water supply and drainage, and gas pipes because of their advantages such as small water loss, energy saving, material saving, ecological protection, and convenient completion. They have become the main force of urban construction pipe networks in the new century. [0003] Compared with tra...
