Embodiment 1

[0019] A kind of epoxy mica gray primer, its mass parts composition is as follows: 20 parts of epoxy resins, 20 parts of acrylic resins, 10 parts of micaceous iron oxides, 2 parts of aminoethylpiperazines, 2 parts of acrylic acid, polyacrylamide, fatty acid 0.2 parts of polyethylene glycol ester, 0.2 parts of polyoxyethylene surfactant, 20 parts of thinner, and 0.08 parts of organically modified bentonite.

[0020] The mass parts of the diluent in the present invention consist of: 50 parts of xylene, 10 parts of cyclohexanone, and 40 parts of isobutyl acetate.

[0021] In the present invention, organically modified bentonite is added, the coating has good leveling property, no sag phenomenon, and prolongs the settling time of the pigment.

[0022] The polyethylene glycol fatty acid ester added in the invention is easily soluble in oil and organic solvents, and has good smoothing and emulsifying effects, which further improves the flexibility, adhesion and impact resistance of ...

Embodiment 2

[0024] A kind of epoxy mica gray primer, its mass parts are composed as follows: 25 parts of epoxy resins, 22 parts of acrylic resins, 12 parts of mica oxidation, 3.5 parts of diethylaminopropylamine, 3 parts of acrylic acid, methyl amyl alcohol, fiber 0.5 part of vegetable derivatives, fatty acid polyethylene glycol ester, 0.3 part of soybean lecithin, propylene glycol, 22.5 parts of diluent, and 0.1 part of N-methylpyrrolidone solution of modified polyurea.

[0025] The mass parts of the diluent in the present invention consist of: 50 parts of xylene, 10 parts of cyclohexanone, and 40 parts of isobutyl acetate.

[0026] The N-methylpyrrolidone solution of modified polyurea added in the present invention is selectively incompatible with the primer system, and at an appropriate stirring speed, produces fine, needle-like crystals, and through the bonding force between crystals, A three-dimensional network structure is formed, which provides a strong thixotropy for the system, a...

Embodiment 3

[0029] A kind of epoxy mica gray primer, its mass parts are composed as follows: 30 parts of epoxy resins, 25 parts of acrylic resins, 15 parts of micaceous iron oxides, trimethylhexamethylenediamine, hexamethylenediamine modified 5 parts 4 parts of acrylic acid, 0.8 part of cellulose derivatives, polyacrylamide, fatty acid polyethylene glycol ester, 0.5 part of sulfonated oil, propylene glycol, 25 parts of diluent, and 0.12 part of organically modified bentonite.

[0030] The mass parts of the diluent in the present invention consist of: 50 parts of xylene, 10 parts of cyclohexanone, and 40 parts of isobutyl acetate.

Abstract

The invention relates to the technical field of oil paints, in particular to an epoxy micaceous iron ash primer. The epoxy micaceous iron ash primer comprises the following components in parts by weight: 20-30 parts of epoxy resin, 20-25 parts of acrylic resin, 10-15 parts of mica iron oxide, 2-5 parts of curing agent, 2-4 parts of acrylic acid, 0.2-0.8 part of dispersing agent, 0.2-0.5 part of wetting agent, 20-25 parts of diluent and 0.08-0.12 part of anti-settling agent. The technical scheme provided by the invention has the following beneficial effects: organic modified bentonite is added in the epoxy micaceous iron ash primer so that the leveling property of a coating is good without sagging, and the settling time of the pigments is prolonged; furthermore, the epoxy micaceous iron ash primer provided by the invention hardly falls off, can be quickly dried, has strong impact force resistance, excellent adhesive force, flexibility, water resistance and excellent anti-rust performance, is environment-friendly, and has no harm to a human body in construction.

Description

technical field [0001] The invention relates to the technical field of paints, in particular to an epoxy mica gray primer. Background technique [0002] A primer is the first layer of a paint system and is a paint that is applied directly to the surface of an object as a solid base for the topcoat. It is used to improve the adhesion of the topcoat, increase the fullness of the topcoat, provide alkali resistance, and provide anti-corrosion functions, etc., while the primer focuses on improving adhesion, anti-corrosion function, anti-alkali, etc. Absorbs to get the best out of the paint system. It is required to adhere firmly on the object surface to increase the adhesion of the upper coating and improve the decorativeness of the top coating. According to the coating requirements, it can be divided into primer primer, secondary primer and so on. [0003] The existing epoxy micaceous iron gray primer is not easy to adhere to the smooth plane, and it is easy to fall off, whic...
