55～65 parts of polyvinyl butyral acetals

5～11 parts of Resins, epoxy

20～30 parts in intermediate

1～6 part of strontium yellow;

Wherein, the mixture weight component of intermediate is:

10～20 parts of Resins, epoxy (E-448)

10～20 parts of dibutyl phthalate (DBP)s

30～40 parts of Viscotrol C

1～6 part of glycerine

The liquid that is mixed with;

The manufacture craft of intermediate is:

(1), inserts and carried out sand milling in the sand mill 2～4 hours and mix thoroughly by mixture weight part extracting epoxy resin, Viscotrol C and glycerine;

(2) add dibutyl phthalate (DBP) and the pigment of being got by weight, mix thoroughly;

(3) with the above mesh screen of 200 orders, step (2) gained mixture is filtered;

(4) pack standby, finished product.

The manufacture craft of B liquid is:

(1) getting polyvinyl butyral acetal, strontium yellow and Resins, epoxy mixing by the composition by weight of mixture mixes thoroughly;

(2) add the intermediate that component is by weight got at the mixture of step (1), insert together to mix in the sand mill and mix thoroughly, and ground 2～4 hours;

(3) mixture in the step (2) is filtered through 200～350 purpose mesh screens;

(4) finished product packing.

The cooperation ratio of A, B liquid is: A: B=2～2.6: 1, and mix and can use after mixing thoroughly, under the thicker situation of steel part surface iron rust, the deal of A liquid can suitably increase.The time of using is from mixing thoroughly, in 8 hours, and the available surface that is coated with, is sprayed on iron and steel.

Above-mentioned A, B liquid mixture are light yellow liquid, before use, remove floating rust, oil stain and the dust of steel surface, but not need to grind, brush away the iron rust of steel surface, and thicker floating rust is as long as do general the removing.When being coated with or being sprayed on the steel surface of rusty stain, this priming paint is colourless, after about 30～60 minutes, through producing chemical reaction with iron rust, from the colourless paint films that becomes the Chinese cymbidium look, tightly is bonded on the metallic surface, plays the effect of protection steel surface.Through check, its viscosity is 200, and be 24 hours time of drying, 2 grades of sticking power, and shock strength 50 reaches and surpasses the requirement of national HG/T 3347-1987 to priming paint.The operation that is coated with, sprays is the same with existing priming paint, and is simple and convenient.Its biggest advantage is to have removed heavy mill, brush treatment operation from, significantly reduces the pollution to environment, has improved working efficiency, reduces cost, and steel surface is played effective protection.Thereby achieve the goal.
