Problems solved by technology

These formulas conform to a certain extent with the mechanical properties of the varnish solution on metals tested by national standards, such as stiffness, toughness and anti-aging performance. Baking at a temperature of ℃ for 20 minutes is not only inconvenient for construction but also consumes a lot of energy. The traditional low-temperature baking paint needs to be added with acid as a catalyst, which is extremely unstable in storage and has certain dangers.

Embodiment 1

[0016] According to the formula in the above-mentioned technical scheme, the parts by weight of each component are respectively:

[0017] Thermosetting acrylic resin 57.5;

[0018] High imino resin 12.6;

[0019] N-butyl etherified amino resin 11.4;

[0020] epoxy resin 2.8;

[0021] Ethylene glycol butyl ether 3.2;

[0022] n-Butanol 4;

[0023] Xylene 6;

[0024] Polyether modified solution 0.5;

[0025] Special non-ionic compound 1.

[0026] The above-mentioned weighed raw materials are mixed uniformly according to the conventional method to make a paint, and then the paint is coated on the surface of a magnesium alloy sample in the same way as other paints, and then baked at a temperature of 100 ° C for 20 minutes, and then Inspect the generated paint film. After inspection, the baking paint is suitable for iron-based, stainless steel, electroplating substrates, etc. It has strong adhesion, excellent solvent resistance, chemical resistance and impact resistance, and...

Embodiment 2

[0028] According to the formula in the above-mentioned technical scheme, the parts by weight of each component are respectively:

[0029] thermosetting acrylic resin 57;

[0030] High imino resin 10;

[0031] N-butyl etherified amino resin 11;

[0032] epoxy resin 2.5;

[0033] Ethylene glycol butyl ether 3;

[0034] n-Butanol 3;

[0035] Xylene 4.9;

[0036] Polyether modified solution 0.4;

[0037] Special non-ionic compounds 0.8.

[0038] This component can reach the effect of embodiment 1 equally.

[0039] Wherein, the special non-ionic compound in the above two embodiments may be non-ionic compound without silicone.

[0040] The baking varnish composition of the present invention only needs 100°C during baking, which is lower than the usual baking temperature of 150-180°C, but has better performance, is convenient to operate, and saves energy.

Abstract

The invention discloses a baking varnish composition, the main contents of which by weight percentages are: thermosetting acrylic resin: 50-57.5, high imino resin: 10-12.6, n-butyl ether amino resin: 8-11.4, epoxy resin: 2-2.8, solvent: 8-13.2, flatting agent: 0.2-0.5 and adhesion promoter: 0.5-1. The thermosetting acrylic resin, the high imino resin, the n-butyl ether amino resin and the epoxy resin are main film forming matters and the solvent is ethylene glycol monobutyl ether, n-butanol and xylene. The varnish of the invention has low baking temperature, high hardness, strong adhesion, as well as little energy consumption and excellent corrosion resistance and impact resistance.

Description

technical field [0001] The invention relates to a solvent-based baking varnish composition, in particular to a low-temperature, high-hardness solvent-based baking varnish composition. Background technique [0002] Baking paint has developed very rapidly in recent years, and many formulas have appeared. These formulas conform to a certain extent with the mechanical properties of the varnish solution on metals tested in national standards, such as stiffness, toughness and anti-aging properties. Baking at a temperature of ℃ for 20 minutes is not only inconvenient for construction but also consumes a lot of energy. The traditional low-temperature baking paint needs to add acid as a catalyst, which is extremely unstable in storage and has certain risks. Therefore, it was of great significance to develop a paint with excellent performance for high-tech metal products. Contents of the invention [0003] In view of the above problems, the present invention provides a low-tempera...
