Coating for screws of wheel hubs for trucks

Abstract

A coating used for the screws of the wheel hub of a truck, which relates to the technical field of wheel hub processing and production, is characterized in that: it is made of the following materials in parts by weight, resin 11-17 parts, nylon 12 6-10 parts, sodium tripolyphosphate 1 ‑4 parts, 4‑9 parts of dicumyl peroxide, 7‑13 parts of modified fluorite, 2‑7 parts of polyoxypropylene glycol, 2‑7 parts of propylene glycol adipate, 2‑hydroxy‑4 ‑1‑5 parts of n-octyloxybenzophenone, 2‑6 parts of triphenyl phosphite, 4‑9 parts of polyurethane acrylate, 7‑12 parts of polyester polyol, 3‑8 parts of polyisobutylene, trifluoro 1-3 parts of europium acetylacetonate, 8-15 parts of defoamer, 8-15 parts of anti-aging agent, 5-10 parts of biomass auxiliary materials, 20-27 parts of deionized water. The invention has the advantages of reasonable method, convenient operation, wear resistance and corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of hub processing and production, in particular to a coating used for screws of a truck hub. Background technique [0002] The hub is a barrel-shaped, center-mounted metal part on the axle that supports the tire inside the tire. Also called rim, steel ring, wheel, tire bell. 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 relatively economical and the color is beautiful and l...

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 screw is a device connecting the car and the tire. This device is very common, but due to its shape and size, there will be a lot of wear and tear during installation and use, which is easy to rust. It is very cumbersome and dangerous to operate
