Problems solved by technology

Otherwise, there will be a problem of bleeding between the paint strips of the two colors. Generally speaking, the blue paint sprayed on the upper part of the steel drum will be strung into the white paint strip sprayed on the lower part of the steel drum, which will affect the coating effect of the steel drum
However, the advance preheating step of the steel drum body not only makes the steel drum coating process steps cumbersome, but also consumes energy and increases the production cost of the enterprise

[0045] The invention discloses a water-based cold bucket red-yellow paint, which comprises water-based bright red paint and water-based yellow paint, and the red paint and the yellow paint are sprayed on the cold bucket to form alternate red bands and yellow bands.

[0046] The big red paint is composed of the following components by weight: 36 parts of acrylic resin, 10 parts of amino resin, 3.5 parts of wetting and dispersing agent, 3.5 parts of adhesion promoter, 6 parts of cosolvent, 4.7 parts of water, compounding additive 5 parts of one, 5.8 parts of titanium white pulp, 22 parts of permanent red pulp, and 3.5 parts of compound auxiliary agent two.

[0047] The wetting and dispersing agent is selected from HD2010 water-based dispersing agent produced by Guangzhou Houhuan Chemical Auxiliary Co., Ltd. The adhesion promoter is selected from the HF-1 adhesion promoter produced by Japan HF Company. The co-solvent is selected from the H-66 polyether phosphate low-foaming co-s...

Embodiment 3

[0060] The invention discloses a water-based cold barrel red and white paint, which comprises water-based red paint and water-based white paint. The red paint and the white paint are sprayed on the cold barrel to form alternate red bands and white bands.

[0061] The red paint is composed of the following components by weight: 40 parts of acrylic resin, 10 parts of amino resin, 4 parts of wetting and dispersing agent, 4 parts of adhesion promoter, 6 parts of cosolvent, 5 parts of water, and a compounding additive 4 parts, 8 parts of titanium white pulp, 20 parts of iron oxide red pulp, 3.5 parts of compound auxiliary agent two.

[0062] The acrylic resin is selected from the epoxy-modified silicone grafted acrylic emulsion (ML-195) produced by Shanghai Badefu Industrial Co., Ltd. The amino resin is selected from melamine formaldehyde resin (MF). The wetting and dispersing agent is selected from HD2010 water-based dispersing agent produced by Guangzhou Houhuan Chemical Auxilia...

Abstract

The invention discloses waterborne cold bucket color-processing baking finish. The waterborne cold bucket color-processing baking finish is prepared from the following components in parts by weight: 35 to 45 parts of acrylic resin, 10 to 12 parts of amino resin, 3 to 4 parts of a wetting dispersant, 3 to 4 parts of an adhesion accelerant, 5 to 7 parts of a co-solvent, 4 to 5 parts of water, 4 to 6parts of a compound auxiliary agent I, 15 to 50 parts of pigment slurry and 3 to 8 parts of a compound auxiliary agent II, wherein the wetting dispersant is an acid group modified polyacrylate ethanol solution; the compound auxiliary agent I is a mixed solution obtained by mixing a polyether modified polydimethylsiloxane co-polymer and an alcohol solvent; the weight part ratio of the polyether modified polydimethylsiloxane co-polymer to the alcohol solvent is 1 to (1 to 3); the compound auxiliary agent II is a nonionic surfactant. According to the waterborne cold bucket color-processing baking finish disclosed by the invention, two types of coating with different colors can be sprayed on an outer wall of a steel bucket at intervals under the condition that an outer wall of the steel bucket is not pre-heated and a mutual color bleeding problem does not occur; the waterborne cold bucket color-processing baking finish has the characteristics of clear color-processing tangent line, breezing, no color bleeding and the like.

Description

technical field [0001] The invention relates to the paint industry, in particular to a water-based baking varnish specially used for steel drums, in particular to a water-based color-coating baking varnish for cold barrels. Background technique [0002] Steel drum paint is used for coating the outer wall of steel drums. In order to improve the decorative effect, it is necessary to coat the outer wall of the steel drum with color paint, that is, to form different paint bands on the outer wall of the steel drum. For example, to paint the outer wall of the steel drum horizontally Install red tape and white tape, or paint blue and white paint tape on the outer wall of the steel drum. However, whether the color steel drum paint used in the market is solvent-based steel drum paint or water-based steel drum paint, it is necessary to preheat the drum body to 70-80°C in advance before spraying, and then the two colors of paint can be sprayed at the same time , high temperature bakin...
