A kind of anti-skid wear layer with high bonding strength and preparation method thereof

Abstract

The invention specifically relates to an anti-skid wear layer with high bonding strength and a preparation method thereof, which solves the problems of rapid attenuation of anti-skid coefficient, easy cracking and stress imbalance in the existing anti-skid wear layer. A non-slip wear layer with high bonding strength is composed of the following raw materials in parts by mass: 30-35 parts of emulsified rubber asphalt; 20-25 parts of self-emulsifying epoxy resin emulsion; 5 parts of alkylphenol polyoxyethylene ether ; 2 parts of monoglyceride; 10‑15 parts of water; 35 parts of emery; 3‑5 parts of chopped carbon fiber. The invention enhances the cross-linking reaction of epoxy resin and rubber asphalt to form an integrated cross-linking structure; furthermore, it promotes the degradation of waste rubber powder; at the same time, it prolongs the demulsification time and increases the operation time.

Description

technical field [0001] The invention relates to the field of road repair and maintenance, in particular to an anti-slip wear layer with high bonding strength and a preparation method thereof. Background technique [0002] With the gradual completion of the construction of expressways in our country, most of the expressways have entered the initial maintenance stage. A large number of expressways have fine cracks in the early stage, and diseases such as the decline of the road surface anti-skid coefficient in the middle stage. In order to solve the above problems, the more effective way is to use anti-skid The wear layer not only solves the problem of water seepage in tiny cracks, but also solves the problem of low friction coefficient of the road surface. [0003] At present, due to the low viscosity and weak bonding strength of emulsified asphalt or latex-modified emulsified asphalt as the wear layer of emulsified asphalt, the durability of the anti-skid wear layer is insuf...

AI Technical Summary

Problems solved by technology

[0006] The present invention provides a non-slip wear layer with high adhesive strength and a preparation method thereof in order to solve the problems that the anti-slip coefficient decays quickly, is easy to crack and is prone to stress imbalance in the existing anti-skid wear layer

[0008] The addition of alkylphenol polyoxyethylene ether and monoglyceride further improves the miscibility of emulsified rubber asphalt and self-emulsifying epoxy resin emulsion, prolongs the construction time, and overcomes the low attenuation of anti-skid coefficient in the existing anti-skid wear layer. Fast, easy to crack and prone to stress imbalance problems
