Problems solved by technology

[0004] 2. Paint coating, easy to operate but poor adhesion, life, and easy to burn
[0005] 3. Ceramic coating has good protective and decorative effects. It has excellent characteristics such as high temperature resistance, acid and alkali resistance, and friction resistance. It is a good material, but the production of large items is limited by equipment
[0006] 4. FRP coating is a very good anti-corrosion material. It is easy to operate and can be used normally under various harsh conditions such as the surface, underground, high cold, freezing, humidity, acid and alkali, etc. The disadvantage is that it is flammable
However, the impact resistance and fire resistance of this type of coating need to be improved.

Embodiment 1 3

[0034] The preparation of embodiment 1 melamine resin

[0035] Add 25 grams of corn amylose and 100 grams of distilled water into the three-hole reaction kettle, stir and heat at 80°C to gelatinize the starch,

[0036] Add 5 grams of hydrochloric acid (the mass concentration of hydrochloric acid is 20%), and now the pH value of the reaction mixture is controlled to be 5; the temperature is raised to 95° C. for 90 minutes, and the mediator saturated calcium carbonate aqueous solution is added dropwise, and the dropwise addition is stopped when the measured pH value is 10 , naturally cooled to 75°C. Add 10 grams of paraformaldehyde and 5 grams of polyvinyl alcohol, and keep it for 30 minutes after they are completely dissolved. At this time, the liquid is in a clear state.

[0037] Add 25 grams of melamine into the reaction kettle and adjust the pH value to 10 with a regulator saturated calcium carbonate aqueous solution, measure and adjust the pH value every 20 minutes, and ke...

Abstract

The invention provides a non-inflammable impact-resistant metal surface coating. The coating is prepared from, by mass, 100 parts of melamine resin, 9-14 parts of curing agent, 0.3-0.5 part of antifoaming agent, 0.5-1 part of flexibility enhancer, 0.01-0.03 part of coupling agent, 5-8 parts of enhancer, 18-25 parts of filler, 0-1 part of pigment and 0-9 parts of diluent. The metal surface coating solves the problem that a metal surface coating material mainly made of resin is inflammable. The melamine-starch resin in the coating has strong adsorption capacity, and the coating will become a solid protection layer after being sprayed on a metal surface and cured.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a non-combustible metal coating containing melamine resin. Background technique [0002] Metal surface coating refers to the protective layer coated with powder coating on the metal surface, and its function is to improve the metal's ability to resist acid and alkali, rust and wear. According to the different coatings, it can be divided into: [0003] 1. Stainless metal coating (electroplating, spraying, etc.), not only can make the surface of the equipment beautiful, but also can prevent the equipment from rusting and corrosion. restrictions, the general factory does not have such a workshop [0004] 2. Paint coating, easy to operate but poor adhesion, lifespan, and easy to burn. [0005] 3. Ceramic coating has good protective and decorative effects. It has excellent characteristics such as high temperature resistance, acid and alkali resistance, and friction resistance. It is a good ...
