Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of road marking paint preparation, and particularly relates to a novel two-component road marking paint. BACKGROUND

[0002] Road traffic marking is mainly drawn on the road surface and is subjected to sun, rain, wind, snow and frost, and is impacted and abraded by vehicles, so strict requirements are imposed on its performance. Road marking is divided into hot-melt marking, normal-temperature cold paint marking, colored anti-skid marking, oscillation anti-skid reflective marking and pre-formed marking. Hot-melt marking is the most widely used marking in China, has a short construction time and high wear resistance. However, a layer of solvent primer is often sprayed on the hot-melt paint before construction, which increases the construction process and makes the construction more inconvenient due to the need for heating. In addition, the hot-melt paint itself is flammable, which poses a safety hazard, and the harmful gases generated during the heating process are also not friendly to the environment.

[0003] Normal-temperature cold paint marking is constructed by spraying, which is relatively easy to construct and is more practical in occasions where road marking needs to be quickly set. However, normal-temperature cold paint marking often has the problems of long drying time and poor wear resistance. Single-component normal-temperature cold paint marking paint also has the problem of slow reaction between the curing agent and the film-forming main material, which is not resistant to storage and transportation. In order to solve the above problems, it is necessary to optimize the formula of road marking paint to meet new demands. SUMMARY

[0004] The purpose of the present application is to provide a novel two-component road marking paint.

[0005] A novel two-component road marking paint, comprising A component and B component, the A component is composed of the following components in parts by weight: fluorosilicon modified epoxy resin 30-50 parts, silicone-acrylic emulsion 20-40 parts, filler 20-40 parts, anti-settling agent 1-3 parts; the B component is composed of the following components in parts by weight: curing agent 8-16 parts, anti-freezing agent 2-5 parts, drying accelerator 1-3 parts, film-forming aid 1-3 parts, toughening agent 2-5 parts.

[0006] The molecular formula of the fluorosilicon modified epoxy resin is as follows:

[0007]

[0008] The preparation method thereof refers to the method disclosed in patent publication CN 111635503 A.

[0009] The filler is one or more of glass beads, shell powder, silicon dioxide and kaolin.

[0010] The curing agent is a mixture of dibenzoyl peroxide and the compound of the following molecular formula in a mass ratio of 1:1:

[0011]

[0012] The anti-settling agent is one or more of magnesium aluminum silicate, sodium bentonite, N, N-methylene (ethyl) bisacrylamide, and methyl methacrylate triphenyl ethyl polyoxyethylene ether.

[0013] The anti-freezing agent is one or more of propylene glycol, glycerol, and ethylene glycol.

[0014] The drying catalyst is one or more of T-12 drying catalyst, zirconium naphthenate, zinc naphthenate, and manganese naphthenate.

[0015] The film-forming aid is one or more of propylene glycol butyl ether, diethylene glycol butyl ether, propylene glycol methyl ether acetate, and propylene glycol ethyl ether acetate.

[0016] The toughening agent is one or more of liquid butyl nitrile rubber, methyl methacrylate (vinyl) end group butadiene, butadiene-acrylonitrile, and polyvinyl butyral.

[0017] The preparation method of the novel two-component road marking paint is performed according to the following steps:

[0018] (1) According to the weight fraction, 30-50 parts of fluorosilicon modified epoxy resin, 20-40 parts of silicone-acrylate emulsion, 20-40 parts of filler, and 1-3 parts of anti-settling agent are taken, fully stirred, filtered, packaged, and A component is prepared;

[0019] (2) 8-16 parts of curing agent, 2-5 parts of anti-freezing agent, 1-3 parts of drying catalyst, 1-3 parts of film-forming aid, and 2-5 parts of toughening agent are taken, fully stirred, filtered, packaged, and B component is prepared;

[0020] (3) When used, A component and B component are mixed in a mass ratio of (0.5-3):1, sprayed on the road surface by using a gun outside.

[0021] The two-component road marking paint of the present application overcomes the defects of traditional road marking paint, such as poor storage resistance, long drying time, and poor wear resistance. The combination of fluorosilicon modified epoxy resin and silicone-acrylate emulsion in the component increases the wear resistance of the material, the use of composite curing agent reduces the curing time of the material, and the combination of the two has a synergistic effect.
