Embodiment 1

[0010] A cold-rolled steel stamping part baking paint, the formula is composed of the following components in weight percentage: 30% saturated polyester resin, 20% high imino resin, 10% acrylic resin, 5% xylene, oxalic acid 12% %, co-solvent 2%, defoamer 1%, dispersant 2%, water to make up to 100%. Co-solvents are sodium benzoate and salicylic acid; defoamers are polyester-modified silicones and high-carbon alcohols; dispersants are ethylene-acrylic acid copolymers and copper stearate. The baking varnish with this ratio has superior performance and high hardness.

Embodiment 2

[0012] A cold-rolled steel stamping part baking paint, the formula is composed of the following components in weight percentage: saturated polyester resin 37%, high imino resin 28%, acrylic resin 11%, xylene 7%, oxalic acid 15% %, co-solvent 4%, defoamer 2%, dispersant 3%, water to make up to 100%. Co-solvents are sodium benzoate and salicylic acid; defoamers are polyester-modified silicones and high-carbon alcohols; dispersants are ethylene-acrylic acid copolymers and copper stearate. This ratio of baking varnish has strong wear resistance.

Embodiment 3

[0014] A cold-rolled steel stamping part baking paint, the formula is composed of the following components in weight percentage: 39% saturated polyester resin, 30% high imino resin, 11% acrylic resin, 6% xylene, oxalic acid 16% %, co-solvent 3%, defoamer 2%, dispersant 3%, water to make up to 100%. Co-solvents are sodium benzoate and salicylic acid; defoamers are polyester-modified silicones and high-carbon alcohols; dispersants are ethylene-acrylic acid copolymers and copper stearate. This ratio has stronger adhesion than baking varnish.

Abstract

The invention discloses stoving varnish for a stamping part of a cold-roll steel sheet and relates to the technical field of stoving varnish. The stoving varnish is composed of the following components in percentage by weight: 30-45% of saturated polyester resin, 20-37% of high imino resin, 10-12% of acrylic resin, 5-8% of xylene, 12-18% of oxalic acid, 2-5% of a cosolvent, 1-3% of a defoamer, 2-4% of a dispersant and the balance of water, totaling 100%. The stoving varnish disclosed by the invention is high in hardness, strong in adhesive force and strong in corrosion resistance. The stoving varnish is more economical and applicable than common stoving varnish, satisfies the special demand of the stamping part on stoving varnish, and is fast in drying speed, hard to fall and wear resistant.

Description

technical field [0001] The invention relates to the technical field of baking varnish, in particular to a baking varnish for stamped parts of cold-rolled steel sheets. Background technique [0002] Baking paint is a process in which the workpiece that needs to be painted is sprayed with paint and then baked at a certain time and temperature to achieve our ideal quality effect. Stamping parts are formed by applying external force to plates, strips, pipes and profiles by presses and molds to cause plastic deformation or separation, thereby obtaining workpieces of required shape and size. Compared with castings and forgings, stamping parts have the characteristics of thinness, uniformity, lightness and strength. Stamping can produce workpieces with ribs, ribs, undulations or flanges that are difficult to manufacture by other methods to increase their rigidity. In order to prevent oxidation on the surface of stamping parts and improve the appearance of stamping parts, it is ne...
