Abstract

The invention discloses an asphalt emulsifier and a preparation method and application thereof; the asphalt emulsifier comprises 80-90 parts of a compound shown in the general formula (1), 2-3 parts of lauryl sodium sulfate and 60-80 parts of water, wherein the general formula (1) is R-O-(C2H4O)x-(CH(CH3)-CH2-O)y-(C2H4O)5-H, the group R in the general formula (1) is branched alkyl with 10-16 carbon atoms, x = 6-28, and y = 5-8. Asphalt obtained by applying the asphalt emulsifier disclosed by the invention can meet the application requirements of the asphalt in industries such as coatings, plastics and rubber and in the aspects of pavement paving and the like.

Description

technical field [0001] The invention relates to the technical field of chemical engineering, in particular to an asphalt emulsifier, a preparation method and an application thereof. Background technique [0002] Bitumen is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. It mostly exists in the form of liquid or semi-solid petroleum. The surface is black and soluble in carbon disulfide, carbon tetrachloride. It is also a waterproof, moisture-proof and anti-corrosion organic gelling material. Asphalt can be mainly divided into three types: coal tar pitch, petroleum pitch and natural pitch. Among them, coal tar pitch is a by-product of coking. Petroleum asphalt is the residue after distillation of crude oil. Natural bitumen is stored underground, and some form ore layers or accumulate on the surface of the earth's crust. Asphalt is mainly used in coatings, ...
