Problems solved by technology

[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 gradually replaced by plastic pipes, and because most of the plastic pipes are flammable materials, smoke concentration is generated when burning Large and such pipes have low strength and poor pressure resistance

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...
