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.

Example Embodiment

[0015] Example 3
[0016] The present invention is a kind of asphalt flame retardant modifier, which is made of the following raw materials in parts by weight:
[0017] 2.7 parts of polyether modified polydimethylsiloxane, 2.3 parts of FDN superplasticizer, 4.7 parts of sodium hypochlorite, 2.8 parts of aminobenzenesulfonamide, 3.7 parts of cetyltrimethylammonium chloride, 10 parts of deionized water , 3.3 parts of calcium carbonate and 2.7 parts of polyvinyl chloride.
[0018] Compared with the existing asphalt flame retardant, the asphalt flame retardant modifier of the present invention has the characteristics of good dispersibility, easy addition, safety, environmental protection, etc., improves production efficiency, has no working environment pollution and less equipment corrosion ; Using polyether modified polydimethylsiloxane and aminobenzene sulfonamide as flame retardants, the flame retardant ingredients are properly matched, and the synergistic effect of multiple flame retardants is fully exerted. It is efficient and directly blended and added to simplify the production process. ,reduce manufacturing cost.
