Amino alkyd paint is a kind of high-grade baking paint. It is made of amino resin and alkyd resin. As a paint material, simple amino resin cured by heat, the paint film is hard and brittle, and poor adhesion. It gets better modification after cooperating with alkyd resin: Amino resin improves the hardness, gloss, drying speed as well as alkali and oil resistance of alkyd resin; alkyd resin improves the brittleness and adhesion of amino resin. Therefore, the characteristics of amino alkyd paint are as follows: light color of varnish; full appearance of paint film, bright colors; paint film is firm, strong adhesion; film aging resistance, anti-chalking, anti-cracking properties; drying not back to viscosity, impact does not fall off; construction performance is good, the film is not easy to wrinkle, good leveling; considerable resistance to acid, alkali, water, oil, abrasion resistance, with good electrical insulation properties; the construction can shorten the drying time, improve production efficiency. It can shorten the drying time, improve the production efficiency and facilitate the continuous baking production of paint. Amino alkyd paint is widely used, such as metal parts for construction, agricultural machinery, transportation, instruments, bicycles, sewing machines, hot water bottles, medical equipment, electrical and electronic equipment and other small metal objects. Amino alkyd paint must be dried by baking, baking paint and other paint compared to its
advantages, but there are obvious shortcomings:
(1) baking paint in the solvent has a strong irritating odor, unlike nitro paint can be constructed in the open air or spacious workshop, baking paint workshop, such as air is not unobstructed, easy to occur poisoning. Therefore, it is necessary to strengthen labor protection and explosion-proof fire prevention measures.
(2) Baking paint to have temperature control baking room equipment. Large investment, serious pollution.
(3) The temperature control of baking paint is quite strict. When the temperature is too high, it will cause the paint film brittle, loss of light, discoloration and other ills; when the temperature is too low, it will cause the paint film becomes soft, poor water resistance, low adhesion and other ills. For this reason, the operator must continue to summarize experience,
