Abstract

The present invention discloses a preparation method of antirust and antisepsis lacquer; 100g of refined castor oil is added into a reaction bottle; and the temperature rises to 110 DEG C to make pressure-decreasing and dehydration operation; the temperature decreases to less than 45 DEG C; and then 360g of solvent is added to be milled; after being milled evenly, 10g of diisocyanate is added to be heated for 0.5 hours and the temperature rises to 85 DEG C to be reacted for 1 hour; and then 250g of diisocyanate is added to be reacted continually; after stopping the reaction, the temperature decreases to 50 DEG C so as to obtain pre-protomer; 720g of pre-protomer is added into a reaction bottle with the capacity of 1000ml, and then 0.79g of cyanogens ammonia formaldehyde resin, 40g of red ferric oxide and 10g of antioxidant are added to be milled for 30 minutes in high speed mode in 50 DEG C temperature. The present invention can be obtained. The present invention has the advantages of much stronger adhesive ability, much better elasticity, tough and smooth, wearable, eroding-resisting to acid, alkali, salt and other common solvent. The storing performance for the present invention is also stable.

Description

technical field [0001] The invention relates to a preparation method of an antirust and anticorrosion paint. Background technique [0002] The isocyanate component in the traditional one-component anti-corrosion coating formulation is single, and the paint film is hard and brittle. Contents of the invention [0003] The purpose of the present invention is to overcome above-mentioned defective, a kind of preparation method of antirust anticorrosion paint is provided. [0004] The technical solution of the present invention is: a preparation method of anti-rust and anti-corrosion paint, which is characterized in that: put 100g of refined castor oil into the reaction flask, heat up to 110°C, carry out dehydration under reduced pressure for 1h, vacuum degree -0.092Mpa, Cool down to below 45°C, add ethylbenzene, ethyl acetate and 2-pentanone in a ratio of 1:1:2 and mix 360g of solvent, stir evenly, add 10g of diisocyanate under stirring, heat up for 0.5h, heat up to 85°C, Rea...
