Pressure resistant, fire prevention and smoke abatement chlorinated polyvinyl chloride (CPVC) tube, fittings and valve composition for fire-fighting

Abstract

The invention relates to a pressure-proof, waterproof and smoke-removed chlorinated polyvinyl chloride (CPVC) pipeline for fire fighting, a fitting part and a valve composition. Manufacturing materials of the pipeline consists of a chlorinated polyvinyl chloride resin finished product material, a toughener and an inorganic flame retardant; and the chlorinated polyvinyl chloride resin finished product material, the toughener and the inorganic flame retardant (a master batch) are mixed to prepare a finished product according to proportion 1:0.05:0.05-0.1. The invention determines to use the chlorinated polyvinyl chloride (CPVC) resin as a main material and use the toughener and the organic flame retardant for assistance to prepare the product through corresponding processing equipment; and the product has good fireproof performance, low flame expansibility, low smog production, automatic extinguishment, no production of fire drops and the like.

Description

technical field [0001] The invention relates to fire-fighting pipes, in particular to the manufacture and application of pressure-resistant, fire-proof and smoke-extinguishing chlorinated polyvinyl chloride pipes, fittings and valve compositions for fire-fighting. Background technique [0002] Fire-fighting pipes are widely used in hotels, hotels, residences, hospitals and commercial buildings abroad. In developed countries such as the United States, CPVC fire-fighting pipes have been used for fifteen years. Its advantages are: [0003] 1. Better water transport function; [0004] 2. Good pressure resistance, fire prevention and smoke reduction ability; [0005] 3. The pipe is lighter than the traditional fire-fighting pipeline; [0006] 4. The installation method is fast and reliable. [0007] Traditional fire pipes are mostly steel pipes, cement pipes or composite pipes, which have the disadvantages of high energy consumption and difficult installation, etc., and are g...
