Abstract

The invention discloses an antibacterial PPR (polypropylene random copolymer) water supply pipe of high low-temperature toughness, made from, by weight, 80 to 100 parts of PPR, 20 to 30 parts of polyisocyanurate, 15 to 25 parts of PA66 (polyamide 66), 3 to 10 parts of antioxidant, 2 to 8 parts of light stabilizer, 5 to 15 parts of organic antibacterial agent, 1 to 5 parts of dispersant, 4 to 8 parts of color masterbatch, and 1 to 5 parts of clay nano-composite. The antioxidant is one of 2, 6-tert-butyl-4-methylphenol and distearyl thiodipropionate. The light stabilizer is a combination of light stabilizer LQ-292 and light stabilizer 765 in any proportion. The organic antibacterial agent is one of vanillin and ethyl vanillin. The dispersant is vinyl distearamide. The clay nano-composite is phyllosilicate nano-material. The antibacterial PPR water supply pipe has excellent low-temperature toughness, oxidation resistance and light stability, is high in strength, can inhibit and kill germs in the pipe, is safe and environment friendly and high in cost performance and has promising market prospect.

Description

technical field [0001] The invention relates to the field of pipes, in particular to an antibacterial PPR water supply pipe with strong low-temperature toughness. Background technique [0002] PPR, also known as random copolymerized polypropylene (PPR), has good toughness, high strength, excellent processability, good creep resistance at higher temperatures, and has the unique advantages of high transparency of random copolymerized polypropylene. Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, PPR pipes have the advantages of energy saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall without scaling, easy construction and maintenance, and long service life. Widely used in building water supply and drainage, urban and rural water supply and drainage, city gas, electric power and optical cable sheathing, industrial fluid transportation, agricultural irrigation and other const...
