Thermoplastic-elastomer-modified polymethyl methacrylate color antiskid paint

Abstract

The invention provides a thermoplastic-elastomer-modified polymethyl methacrylate color antiskid paint. The paint is of a three-component reaction type and comprises a component A, a component B and a component C, wherein the ratio of the component A to the component B to the component C is 100 to (50-200) to (5-30); and the paint is formed by mixing the three components. The component A is MMA resin liquid modified by thermoplastic elastomer and tackifying resin, the component B is graded waste tire rubber particles, and the component C is formed by mixing and dissolving 2 to 3 parts of benz peroxide and 10 to 30 parts of dibutyl phthalate. The thermoplastic-elastomer-modified polymethyl methacrylate color antiskid paint has beneficial effects that an energy-saving, high-efficient and durable color antiskid paint for roads and bridges is provided, the cost can be reduced, the energy consumption can be reduced, the economic benefit and social benefit can be improved, and various technical indexes of the paint can reach or exceed that of the color antiskid paint sold in the market.

Description

technical field [0001] The invention relates to an elastic colored anti-skid pavement paint, in particular to a three-component thermoplastic elastomer modified polymethyl methacrylate (MMA) colored paint. Background technique [0002] At present, the colored non-slip road and bridge coatings on the market generally use two-component adhesives to scrape and coat on concrete or asphalt foundations. Before the two-component adhesives solidify, immediately sprinkle colored ceramsite on the surface. After the adhesives are completely cured, clean and collect uncoagulated Colored ceramsite, and open to traffic. [0003] But the disadvantages of this method are: 1. The efficiency of scraping is low. On average, a skilled worker scrapes 300-500 square meters a day. For urban greenway projects or squares and expressway projects with tens of thousands of square meters, this construction speed It will lead to too long project construction period, affecting economic and social benefi...

[0003] However, the disadvantages of this method are: 1. The scraping efficiency is low. On average, a skilled worker scrapes 300-500 square meters a day, and for tens of thousands of square meters For urban greenway projects or square and expressway projects, this construction speed will lead to a long construction period and affect economic and social benefits

2. The two-component adhesive is usually an epoxy system or a polyurethane system. Due to the influence of temperature and humidity, the curing speed is not constant, which makes it difficult to grasp the timing of throwing colored ceramsite. Too early throwing timing will cause the ceramsite to sink and have an anti-skid effect. Decrease, the consumption of ceramsite will increase; if the throwing time is too late, the contact surface between ceramsite and adhesive will become smaller, the adhesion will not be firm, and it will easily fall off during later use

3. The firing of colored ceramsite consumes a lot of energy, especially the firing temperature required for high-temperature ceramsite is 1200 degrees, which leads to a large amount of energy consumption and high cost of ceramsite

However, the peculiar smell of its special toughening monomer is too heavy, the cured product has poor elasticity, poor matching with elastic fillers, and poor adhesion, so this system cannot be popularized and applied in outdoor color anti-skid applications.
