Problems solved by technology

[0003] In the prior art, low-grade asphalt or low-grade asphalt and matrix asphalt composite technology are generally used to prepare non-stick wheel emulsified asphalt, but this technology has poor elastic recovery of the emulsified asphalt evaporation residue, and the PG grade of the evaporation residue is not high, 60 ℃ low viscosity and other fatal flaws, which affect its bonding effect in interlayer bonding
[0004] Although non-stick wheel emulsified asphalt has many advantages suitable for application, its preparation method has a direct impact on its performance, so it is of great significance to study a preparation method that can improve its PG grade

Abstract

The invention discloses a preparation method of wheel-sticking-free emulsified asphalt for an adhesive layer. The preparation method comprises the following steps: preparing parent asphalt, preparingmodified asphalt, preparing liquid soap, mixing the liquid soap and the modified asphalt, grinding and emulsifying. High-proportion thermoplastic elastomer is used as a modifier for adjusting the low-temperature performance of asphalt, the softening point of the evaporation residues of the prepared wheel-sticking-free emulsified asphalt is as high as 90 DEG C or above, and the PG grade and the binding power at 60 DEG C of the evaporation residues of the emulsified asphalt can be improved.

Description

technical field [0001] The invention relates to a method for preparing asphalt, in particular to a method for preparing emulsified asphalt with non-stick wheels for sticky layers. Background technique [0002] Non-stick wheel emulsified asphalt is a kind of polymer modified emulsified asphalt. It uses petroleum asphalt as the main raw material, and uses surfactants and various chemical additives as auxiliary raw materials. A new type of composite waterproof coating which is modified and re-emulsified. It is an emulsion type waterproof coating, which can be sprayed, rolled or painted by hand. Through the evaporation of demulsification water, the polymer modified asphalt is formed into a film through the process of solid particle approaching, contact deformation, etc. It is a seamless coating. A complete waterproof and moisture-proof polymer modified emulsified bitumen waterproofing membrane. It can be constructed on a variety of wet or dry base surfaces, has good bonding pe...
