40 parts~50 parts of E44 epoxy resin, 10 parts~15 parts of iron oxide red, 3 parts~5 parts of precipitated calcium carbonate, zinc oxide 3 parts~6 Part, 2 parts~5 parts of trbasic zinc phosphate, 0.5 part~1 part of calcium carbonate, four 1 part of alkali zinc yellows~3 parts are 0.5 part~2 parts of chromic acid diphenylguanidine, sliding 3 parts~5 parts of mountain flour, 5 parts~10 parts of blanc fixe, 15 parts~20 parts of solvent；
B component is mixed by the substance of following parts by weight, is made after being dispersed with stirring uniformly:
10 parts~20 parts of polyamide, 15 parts~20 parts of solvent；
Preparation method includes the following steps:
Component A, B component are uniformly mixed by the weight part ratio of 4:1 when use.
In above-mentioned technical proposal, more specific technical solution, which may also is that, to be used when prepared by the component A and B component It is that the ratio of 4:1 is prepared that solvent is by dimethylbenzene, butanol by volume.
Further, the polyamide of the B component is the polyamide that amine value is 300.
Due to the adoption of the above technical scheme, the beneficial effect that the present invention obtains is:
The present invention due to using epoxy resin addition polymerization amide resin as film forming matter so that its with excellent adhesive force, it is water-fast, The performances such as solvent resistant, anti-corrosion, to make it for coating food grade container inner wall more safety and environmental protection.
