Problems solved by technology

[0002] At present, the preferred material for fire-fighting pipes is galvanized steel pipe, but it has many defects: the inner wall is easy to rust, and the rust residue that falls off with the extension of use time will block the pipes and nozzles in the fire-fighting system, seriously affecting fire-fighting Efficiency; In addition, it is heavy, the cost per unit length is high, and the installation is inconvenient. It has been replaced by some plastic pipes
However, at present, the domestic CPVC pipe market is mainly monopolized by individual foreign companies, and the high product price greatly restricts the wide-scale promotion and application

Abstract

The invention discloses fire-fighting CPVC (Chlorinated Polyvinyl Chloride) and a preparation method thereof. The CPVC comprises the following raw materials in parts by weight: 100 parts of CPVC resin, 2.5-3 parts of stabilizer, 3-6 parts of impact modifier, 0.2-1 part of internal lubricant, 1-2 parts of external lubricant, 0.1-0.5 part of flame retardant 1, 1-2 parts of flame retardant 2, 5-20 parts of filler and 0.05-0.1 part of pigments. According to a tubular product prepared by the formula, the physical indexes are in accordance with the national standard of fire-fighting tubular products, and the CPVC is high in compressive strength, good in shock resistance, good in flame retardant effect, good in smoke abatement and low in cost. The vicat softening temperature reaches over 108 DEG C.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a CPVC for fire protection and a preparation method thereof. Background technique [0002] At present, the preferred material for fire-fighting pipes is galvanized steel pipe, but it has many defects: the inner wall is easy to rust, and the rust residue that falls off with the extension of use time will block the pipes and nozzles in the fire-fighting system, seriously affecting fire-fighting Efficiency; In addition, it is heavy, the cost per unit length is high, and the installation is inconvenient. It has been replaced by some plastic pipes. Although plastic pipes can overcome the rust of the pipe wall, most plastic pipes cannot work at high temperatures, and most of them are flammable materials, which will generate smoke when burned, which greatly limits the application of plastic pipes in fire protection piping systems . CPVC pipes have been successfully used in...
