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...

Embodiment Construction

[0052] A method for preparing a high-temperature primer for subway wheels, characterized in that the high-temperature primer for subway wheels includes three parts: a base paint for a high-temperature primer, a curing agent for a high-temperature primer, and a diluent for a high-temperature primer. Made with the following ingredients and steps:

[0053] (1) the weight ratio of each raw material of the basic paint material of the high-temperature primer for the described subway wheel is:

[0054]

[0055] Wherein, the bonding base material is one of methyl phenyl silicone resin and E-20 bisphenol A epoxy resin and E-44 bisphenol A epoxy resin, or two composites;

[0056] Anti-corrosion pigments and fillers are one of mica powder, zinc phosphate, aluminum tripolyphosphate, barium metaborate, ceramic powder, low-temperature glass powder, talc powder, iron oxide series, or a mixture of several;

[0057] The aluminum silver paste is a mixture of aluminum silver powder with high...
