Asphalt flame retardant modifier

Abstract

The invention discloses an asphalt flame retardant modifier, which is composed of the following raw materials in parts by weight: 1.5 to 2.7 parts of polyether modified polydimethylsiloxane, 1.2 to 2.3 parts of FDN efficient water reducer, 2.3 to 4.7 parts of sodium hypochlorite, 1.8 to 2.8 parts of aminobenzene sulfanilamide, 1.5 to 3.7 parts of cetyl trimethyl ammonium chloride, 5 to 10 parts of deionized water, 1.2 to 3.3 parts of calcium carbonate, and 0.8 to 2.7 parts of polyvinyl chloride. Compared with the conventional asphalt flame retardants, the provided asphalt flame retardant modifier has the characteristics of easy addition, safety, and environment-friendliness, improves the production efficiency, and reduces the equipment corrosion. Polyether modified polydimethylsiloxane and aminobenzene sulfanilamide are taken as the flame retardants, the flame retardant components are reasonably compounded so as to generate a synergetic effect, the flame retardant effect is efficient, the raw materials can be directly mixed, thus the production procedure is simplified, and the production cost is reduced.

Description

technical field [0001] The invention relates to an asphalt flame retardant modifier, which belongs to the field of building materials. Background technique [0002] Asphalt is the final product of petroleum refining, and it is a cheap and abundant building material widely used in construction for waterproof, moisture-proof, anti-corrosion, rust-proof, anti-leakage, etc. Some of its properties are unmatched by synthetic rubber and synthetic resin. However, asphalt is easy to burn, produces a large amount of black smoke when burned, melts and flows when heated, and has a great fire hazard, and its application is also subject to certain restrictions. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide an asphalt flame retardant modifier, which has the characteristics of good dispersibility and easy addition. Effectively improve the flame retardant performance of asphalt mi...
