Abstract

An asphalt emulsion coating consists of octadecylic trimethyl-ammonia chloride and epoxyethane mistura, which comprises alkyl polyethenoxy ether, alkyl alcohol amide and alcohol polyoxyethylene ether-sodium sulfate. It has good stability and no environmental pollution.

Description

technical field [0001] The invention relates to an emulsion paint, in particular to a composition and a preparation method of a petroleum asphalt emulsion paint. Background technique [0002] Historically, cast iron pipes have been produced by coal tar pitch hot dipping. In the dip coating project, due to the heating of coal tar pitch, a large amount of pitch smoke containing carcinogens is volatilized, which seriously pollutes the environment. [0003] In September 1982, the Institute of Highway Science of the Ministry of Communications of China and other units put forward a research report entitled "Application of Cationic Emulsified Asphalt in Roads", which proposed a method using 18 alkyl trimethyl ammonium chloride as an emulsifier A method for emulsifying petroleum asphalt with a low softening point (45°C), but the softening point of the emulsified petroleum asphalt that can be emulsified by this method cannot be higher than 45°C. This petroleum emulsified asphalt can...
