MMA (methyl methacrylate)-based colored anti-slip thin-layer paving material and preparation process thereof

Abstract

An MMA (methyl methacrylate)-based colored anti-slip thin-layer paving material is prepared from, by mass, 28-42% of modified methyl methacrylate, 6-12% of n-butyl methacrylate, 2.5-5% of isooctyl acrylate, 3.2-5.5% of fumed silica, 1.5-3.2% of styrene, 1.2-2.3% of high-boiling-point paraffin, 2.1-3.6% of a two-functional-group ethylene-propenyl composite dispersing agent, 8-10% of calcium or magnesium filler, 15-24% of high-hardness natural mineral filler, 0.5-0.85% of N-N-dimethyl p-hydroxyaniline, 0.8-2.8% of a cross-linking agent BPO and 2.5-4.5% of resin based color paste, wherein N-N-dimethyl p-hydroxyaniline and the cross-linking agent BPO are reaction excitation substances. The invention provides a preparation process of the MMA-based colored anti-slip thin-layer paving material. The material is long in stable storage period, quick, convenient and simple in construction, high in adhesion with base planes, environmental friendly, safe, resistant to pollution and chemical corrosion, easy to clean and excellent in physical and chemical performance, has a rich color system and realizes better combination of comfort and slip resistance.

Description

technical field [0001] The invention relates to the field of road pavement materials, in particular to a colored non-slip thin-layer pavement material based on methacrylic resin MMA and its preparation process. The material has high bonding strength, good ductility and tensile strength, and is durable High temperature, excellent anti-skid performance, simple and reasonable process steps, high yield and easy production. Background technique [0002] The Chinese name of MMA is methyl methacrylate, a reactive liquid resin with MMA as the main component, which reacts with the initiator (curing agent) benzoyl peroxide (BPO) to undergo free radical polymerization to form a highly tough resin. Polymer cured product of methyl methacrylate. [0003] Methyl methacrylate is polymerized as follows in the presence of benzoyl peroxide initiator: [0004] [0005] The system initiated by the redox reaction is cured at room temperature. The hard monomer provides rigidity for the coatin...

AI Technical Summary

Problems solved by technology

[0007] 1) After the film is formed, it is easy to delaminate from the base surface, and the service life is short;

[0008] 2) Poor ductility and low tensile strength cannot meet the performance requirements of existing road surfaces;

[0009] 3) Poor high temperature resistance, prone to pulverization at 200°C;

[0010] 4) As a component of the pavement structure layer, the bonding force of the existing product layered construction is too low, resulting in a significant decrease in the overall performance of the pavement layer structure
