Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the examples, but the protection scope of the present invention is not limited by the examples.

[0014] Epoxy primer, which is composed of the following raw materials: additive 0.3kg, linear polyester resin 50kg, aluminum tripolyphosphate 6kg, zinc phosphate 7kg, titanium dioxide 8kg, barium sulfate 8kg, zinc chrome yellow 3kg, strontium chrome yellow 2.7kg, white carbon black 0.3kg, solvent 10kg, amino resin 4kg, leveling defoamer 1kg, catalyst 0.4kg.

[0015] The preparation process of the present invention is as follows:

[0016] Take the linear polyester resin and additives according to the stated weight, start stirring, and then add other raw materials according to the stated weight. When adding, put them in the order of light first and then heavy, stir and mix, stop stirring after dispersing evenly, and transfer to the next step Grinding is carried out in the process, and then th...

Abstract

The invention discloses paint, in particular epoxy primer used for back protection of a hot dipping plate, an aluminum-zinc plate, a cold rolling plate and an aluminum plate, etc. The paint comprises the following raw materials of corresponding part by weight: 0.3 portion of auxiliary agent, 50 portions of linear polyester resin, 6 portions of trimeric aluminum phosphate, 7 portions of zinc phosphate, 8 portions of titanium pigment, 8 portions of barium sulfate, 3 portions of zinc chrome yellow, 2.7 portions of strontium chromate, 0.3 portion of white carbon black, 10 portions of solvent, 4 portions of aminoresin, 1 portion of flatting antifoam agent and 0.4 portion of catalyst. The epoxy primer of the invention contains less volatile organic solvent than the prior products, thereby solving the problem that the prior products cause environmental pollution; moreover, the epoxy primer has strong adhesive force, excellent anticorrosion and salt - fog resistance and low cost.

Description

technical field [0001] The invention relates to a paint, in particular to an epoxy primer which is suitable for protecting the backs of hot-dip galvanized sheets, aluminum-zinc sheets, cold-rolled sheets and aluminum sheets. Background technique [0002] At present, most of the primers available on the market to protect the back of hot-dip galvanized sheets, aluminum-zinc sheets, cold-rolled sheets, and aluminum sheets contain a large amount of volatile organic solvents. Usually, the release of volatile organic solvents will cause pollution to the environment. , while the current primer also has the following technical defects: [0003] 1. Poor adhesion; [0004] 2. Poor anti-corrosion salt spray performance; [0005] 3. High cost. [0006] Because there are above-mentioned defects in existing primer product, so be badly in need of a kind of replacement product. Contents of the invention [0007] The technical problem to be solved by the present invention is to provide...
