Abstract

The invention relates to a high-temperature primer for metro wheels and a preparation method of the high-temperature primer. The high-temperature primer for the metro wheels is prepared from epoxy modified organic silicon resin as a bonding base material, an anticorrosive pigment and filler, aluminum silver paste, an adjuvant, a solvent A as a paint component, low molecular weight modified polyamide resin, cashew oil phenol-modified aromatic amine resin, 4-6 of tris(dimethylamino methyl) phenol, an adhesion promoter (a silane coupling agent), and a solvent B as a curing agent component in a manner of matching with a proper amount of diluent during construction. The invention mainly aims at developing a high-temperature primer product for metro wheels, which has good overall performance, such as high-efficiency anti-corrosion property, excellent salt spray resistance property, high drying speed, strong adhesive force, good physical and mechanical properties, easiness of construction, good chemical resistance, good high-temperature resistance and the like.

Description

technical field

[0001] The invention relates to a high-temperature primer for subway wheels and a preparation method thereof. Background technique

[0002] The high-temperature primer for subway wheels is mainly based on pure silicone or acrylic modified silicone resin, adding zinc phosphate, aluminum tripolyphosphate, iron oxide and other traditional inorganic anti-corrosion and anti-rust pigments, supplemented by talcum powder, barium sulfate, etc. Filler, at the same time add an appropriate amount of dispersant, defoamer, leveling agent, rheological additives, etc. and a mixed solvent. With the improvement of high-temperature primers for subway wheels in terms of anti-corrosion, high-temperature resistance, and adhesion performance, there are mainly two types of solutions: one is a high-temperature coating prepared from pure silicone resin, although it has excellent heat resistance, However, the drying performance at room temperature, solvent resistance, and adhesion are...
