Embodiment 1

[0017] The raw material that the road marking paint of the present embodiment adopts is:

[0018] 40 parts of acrylic emulsion; 1 part of propylene glycol; 4 parts of polyacrylamide; 0.2 parts of silicone oil; 10 parts of titanium dioxide; 50 parts of heavy calcium carbonate; 0.1 part of nonionic surfactant; ; 0.5 parts of ammonia water; 0.5 parts of isothiazole tincture ketone; 3 parts of water;

[0019] Its production steps are:

[0020] (1) Add acrylic emulsion into a high-speed stirring tank, start stirring at 400 rpm, add polyacrylamide, silicone oil, non-ionic surfactant, and isothiazole tincture ketone in sequence and continue stirring for 20 minutes, then add titanium dioxide in sequence and heavy calcium carbonate, slowly increase the stirring speed of the stirred tank to 1000 rev / min, stir for 1 hour;

[0021] (2), (1) After the steps are completed, reduce the stirring speed to 400 rpm, add propylene glycol, hydroxyethyl cellulose thickener, ammonia water, stir for...

Embodiment 2

[0024] The raw material that the road marking paint of the present embodiment adopts is:

[0025] 50 parts of acrylic emulsion; 5 parts of propylene glycol; 0.5 parts of polyacrylamide; 0.5 parts of silicone oil; 5 parts of titanium dioxide; 60 parts of heavy calcium carbonate; 0.2 parts of nonionic surfactant; ; 1 part of triethanolamine; 1 part of isothiazole tincture ketone; 8 parts of water.

[0026] Its preparation method is identical with embodiment 1.

[0027] Embodiment 1 and embodiment 2 are tested, and the performance index is as follows:

Abstract

The invention discloses a water-based traffic paint, relates to the technical field of chemical engineering and is prepared from the following components: 40-50 parts of acrylic emulsion, 1-5 parts of propylene glycol, 0.5-4 parts of polyacrylamide, 0.2-0.5 part of silicone oil, 5-10 parts of titanium dioxide, 50-60 parts of calcium carbonate, 0.1-0.2 part of nonionic surface active agent, 0.1-0.2 part of hydroxyethyl cellulose thickener, 0.5-1 part of pH regulator, 0.5-1 part of isothiazole tincture ketone and 3-8 parts of water. Compared with the prior art, the calcium carbonate and multiple auxiliaries adopted by the invention are subjected to melt blending, and the obtained molecular structure can be well compatible with the acrylic emulsion, thus having good toughness; a coalescing agent is added, so that a paint film has strong chemical stability, and the formed paint has good compatibility, no coloring, hydrolysis resistance, no pollution, hot working resistance, high adhesive force and low possibility of falling off.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a water-based road marking paint. Background technique [0002] Road marking paint is an indispensable material for the modernization of road traffic. At present, there are two main types of road marking paint, solvent-based and hot-melt, which are generally composed of base materials, coloring pigments, fillers, solvents, and additives. Commonly used base materials include polyurethane, epoxy resin, chlorinated resin, vinyl resin and petroleum resin, etc., and chlorinated rubber and acrylic resin are mostly used as film-forming materials for solvent-based road marking paints. However, due to the increasing production of chlorinated rubber in China Less, and the price continues to rise, which limits the development of this type of road marking paint. The road marking paint with acrylic resin as the film-forming material is developed. Acrylic resin has the advantages of ...
