Abstract

The invention discloses a chlorinated polyvinyl chloride tube stock and relates to the field of electric power instruments. The chlorinated polyvinyl chloride tube stock is prepared from the following raw materials in parts by weight: 75 parts of CPVC resins, 50 parts of PVC resins, 25 parts of light calcium carbonate, 12.5-15 parts of MBS resins, 8-10 parts of heat stabilizers, 1-2 parts of lubricants, 5-8 parts of chlorinated polyvinyl chloride, 2-5 parts of ACR processing agents and 0.5-1 part of molybdate red. The invention also discloses a preparation method for the chlorinated polyvinyl chloride tube stock. The preparation method comprises the following three steps: primarily mixing, blending and extruding. According to the preparation method provided by the invention, the formula of the tube stock is optimized; the dosage of the main raw material CPVC resin is less; compared with the traditional technique, the dosage of the CPVC resin is reduced by 30%; a compound toughening system is used for acquiring the tube stock with excellent performance the rigid-tough balance of the tube stock is realized; the shock strength, the tensile yield strength and vicat softening temperature of the tube stock are all at higher level; besides, the preparation technique is optimized, so that the performance requirement of the products meets the scheduled object and the product qualified rate and the productivity are both obviously increased.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a chlorinated polyvinyl chloride pipe and a preparation method for the chlorinated polyvinyl chloride pipe. Background technique [0002] With the advancement of science and technology, PP-R hot water pipes, PE-RT hot water pipes, PB hot water pipes, PE-X hot water pipes and PAP aluminum-plastic composite hot water pipes have been gradually developed to replace the steel pipes or cast iron we usually used before. pipes to carry hot water. [0003] Recently, the development of urban planning and construction as well as the cleanliness and beauty of the city require that the overhead high-voltage wires be buried underground. Due to the high-voltage cables and high voltage, they are prone to heat generation or high temperature due to instantaneous accidental short circuit. People usually use modified polymer Propylene (MPP), steel pipes or glass steel pipes are used as sheath pi...
