Auxiliary paint for steel ring of automobile hub

Abstract

An auxiliary paint for steel rings of automobile wheels, relating to the technical field of automobile wheel processing and production, characterized in that: it is made of the following materials in parts by weight: 11-17 parts of resin, 6-10 parts of phenol, diisoperoxide 4-9 parts of propylene, 125-10 parts of nylon, 4-9 parts of accelerator DM, 1-5 parts of polyester acrylate, 1-3 parts of triethanolamine, 6-12 parts of modified fluorite, 1-6 parts of bamboo charcoal , 5‑10 parts of hexamethylenetetramine, 2‑8 parts of tetramethoxymethyl glycoluril, 8‑15 parts of defoamer, 8‑15 parts of antiaging agent, 5‑10 parts of biomass auxiliary materials, deionized 20‑27 parts of water. The invention has the advantages of reasonable method, convenient operation, high strength and corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of automobile wheel hub processing and production, in particular to an auxiliary paint for steel rings of automobile wheel hubs. Background technique [0002] The hub is a barrel-shaped, center-mounted metal part on the axle that supports the tire inside the tire. Also known as rims, steel rims, wheels, and tire bells. There are many types of hubs according to diameter, width, molding method and material. [0003] The hub is also called the rim. According to the characteristics and requirements of different models, the surface treatment process of the wheel hub will also adopt different methods, which can be roughly divided into two types: baking paint and electroplating. The appearance of the wheels of ordinary models is less considered. Good heat dissipation is a basic requirement. The process is basically treated with baking paint, that is, spraying first and then electric baking. The cost is relativel...

2. The forging method. The whole aluminum ingot is directly extruded on the mold by a thousand-ton press. The advantage is that the density is uniform, the surface is smooth and delicate, the hub wall is thin and light, and the material strength is the highest, which is more than 30% higher than that of the casting method. Due to the need for relatively sophisticated production equipment, and the yield rate is only 50% to 60%, the manufacturing cost is relatively high

[0005] The steel ring is a very important part of the wheel hub. The current steel ring has many layers of paint, but the internal paint of some steel rings often appears after a period of use due to its own material problems and environmental problems. The problem of cracking, which will lead to cracking and peeling of the entire paint surface, which will damage the aesthetics of the appearance, and it will also be dangerous for use
