[0029] Correspondingly, on the basis of providing the formulation of the paint for electric iron, the embodiment of the present invention also provides a preparation method of the paint for electric iron. In an embodiment, the preparation method of the coating for an electric iron at least includes the following steps: weighing acrylic resin, amino resin, epoxy resin, sealed curing agent, toner, auxiliary agent (auxiliary agent includes Dispersants, anti-settling agents, leveling agents, adhesion promoters) and organic solvents;

[0030] Mixing the weighed organic solvent, acrylic resin, dispersant, anti-sedimentation agent, and toner to obtain the first material;

[0031] Grinding the first material;

[0032] adding the amino resin, closed curing agent, and epoxy resin to the first material in sequence, and performing mixing treatment to obtain a second material;

[0033] Add the leveling agent and the adhesion promoter into the second material, and adjust the viscosity.

[0044]

[0045] The preparation process of above-mentioned each embodiment coating is:

[0046] The first material is obtained by first mixing part of the organic solvent with the acrylic resin, dispersant, anti-sedimentation agent, and toner;

[0047] Grinding the first material so that the particles of the first material are 10 microns or less;

[0048] adding amino resin, closed curing agent, and epoxy resin to the ground first material, and mixing to obtain the second material;

[0049] Add the leveling agent and the adhesion promoter into the second material, and use the remaining organic solvent to adjust the viscosity of the paint to obtain the paint for electric irons in various embodiments.

Abstract

The invention provides a paint for electric irons, and a preparation and application method thereof. The paint at least comprises the following components in percentage by weight: 40-60% of acrylic resin, 12-19% of amino resin, 0-5% of epoxy resin, 3-5% of enclosed-type curing agent, 0-28% of toner, 2-5% of aid and 8-20% of organic solvent. The content of the epoxy resin is not 0. The paint is a single-component acrylic amino baking varnish, and has the advantages of favorable spraying effect, smooth surface, high gloss and uniform color. More importantly, the paint film formed by drying at the temperature of lower than 160 DEG C has favorable hardness, and especially can still have higher hot hardness, favorable adhesion to the substrate, excellent damp heat resistance and excellent wear resistance in a 120-DEG C environment.

Description

technical field [0001] The invention relates to the technical field of acrylic amino baking varnish, in particular to a coating for an electric iron and a preparation method and application method thereof. Background technique [0002] There are two main types of existing electric iron coatings: the first type of electric iron coating is suitable for baking varnish coatings of original iron-based materials. Since the paint film needs to meet higher physical property requirements, this type of coating needs to be used in the film-forming process. Baking at a high temperature exceeding 180°C, if the material of modern bakelite or bulk molding compound (also known as unsaturated polyester bulk film plastic; English: Bulk molding compounds; English abbreviation: BMC) is at this temperature for a long time, it will produce As a result, these two materials cannot meet the original process requirements. The second type of paint for electric irons is baking varnish baked at a tempe...
