Quick-drying unsaturated polyester resin marking coating and preparation method thereof

Abstract

The invention discloses a quick-drying unsaturated polyester resin marking coating and a preparation method thereof. The marking coating is prepared from the following raw materials in percentage by weight: 30-50 percent of modified unsaturated polyester resin, 5-12 percent of titanium pigment, 40-50 percent of quartz powder, 2-5 percent of white carbon black, 1-3 percent of kaoline, 0.5-2 percent of titanate coupling agent, 1-3 percent of cobalt naphthenate and 0.5-1.5 percent of methyl ethyl ketone peroxide, wherein the modified unsaturated polyester resin is obtained by the steps of preparing unsaturated polyester resin by performing esterification and condensation on monoester maleate end-capped by dicyclopentadiene and propylene glycol, and adding a methyl methacrylate monomer diluent into the unsaturated polyester resin. The preparation method comprises the following step of: ultrasonically mixing the components with the amount in a formula for 3-7 minutes to obtain a quick-drying unsaturated polyester resin marking coating. During construction, the cobalt naphthenate and the methyl ethyl ketone peroxide are added for curing to form an unsaturated polyester resin marked line, which has the wear resistance superior to that required by a national standard.

Description

Technical field: [0001] The invention relates to a paint, in particular to a quick-drying unsaturated polyester resin road traffic marking paint and a preparation method thereof. Background technique: [0002] Road marking paint is a kind of paint that is applied on the road surface to indicate traffic. At present, there are three types of road marking paints commonly used in the market, mainly including room temperature solvent type, hot melt type and two-component road marking paint. [0003] Normal temperature solvent-based coatings are composed of film-forming substances and organic solvents. During construction, the paint is sprayed from the spray gun, and the solvent is naturally volatilized to form a marking film. The film-forming material usually adopts chlorinated rubber, epoxy resin and the like. The advantages are: the construction is simple, the drying time is relatively short, and it can be opened to traffic in about 3 to 4 hours. At present, it is widely use...

AI Technical Summary

Problems solved by technology

The disadvantage is: pollute the environment

The disadvantage is: high energy consumption

The disadvantages are: 1) high cost of use

Due to the unstable quality of domestically produced acrylic resin products, in order to ensure product quality, marking paint manufacturers usually purchase German DEGAROUTE (Degussa) acrylic resin for production, which is about 30,000 to 40,000 yuan/ton, which directly leads to domestic double Component coating prices
