Problems solved by technology

[0005] The purpose of the present invention is to provide a high-shear and high-adhesion coating material and its preparation method, which solves the problem that the coating material of the existing pavement surface layer has weak cohesive force, which causes the gap between the surface layers of the pavement coating material. Adhesive force is not strong enough to make the pavement multi-layer structure combination system have good structural bearing capacity and durability; at the same time, it solves the poor temperature adaptability of the current coating material on the surface layer and requires special temperature control technology during smear construction question

Abstract

The invention discloses a high-shearing and high-bonding coating material and a preparation method thereof. The coating material is prepared from the following components in parts by weight: 0.4-0.6 part of powdery butadiene-acrylonitrile rubber, 0.2-0.3 part of a flame retardant, 0.2-0.3 part of a stabilizer, 3-5 parts of an asphalt modifier, 15-25 parts of asphaltene powder, 25-35 parts of matrix asphalt and 35-55 parts of a solvent. The coating material disclosed by the invention is reasonable in formula and simple in preparation method, has relatively high shearing strength between layer and bonding force, is good in low-temperature flexibility, free of cracks at -25 DEG C, strong in waterproof performance and great in construction temperature range, and the construction season is prolonged, and moreover, the coating material can be smeared, sprayed or sprinkled under a room temperature condition and is wide in application range.

Description

Technical field [0001] The invention relates to the technical field of coatings, in particular to a high-shear and high-cohesive coating material and a preparation method thereof. Background technique [0002] With the rapid development of my country's social economy, highway construction has developed vigorously. The public has higher requirements for the performance of the road surface. In addition to requiring the pavement structure to meet the basic safety and speed of vehicle operation, it is more demanding to feel the comfort of the vehicle during driving. The substantial nature of the structural layer in contact with the tire directly affects the driving quality of the road surface. [0003] At present, the treatment of pavement diseases is generally to thicken the asphalt surface layer or add a new surface layer, or optimize and improve the base layer, surface layer material and structure combination, often neglecting the problem of interlayer adhesion. At the contact po...
