Embodiment Construction

[0025] A processing method for a plastic socket DJ7032B-3.5-21 on an automobile, comprising the following contents:

[0026] The first step: first weigh the raw materials of the following parts by weight according to the formula:

[0027] Material A:

[0028] 65 parts of nylon PA66, 13 parts of polytetrafluoroethylene, 0.3 parts of methyltriethoxysilane, 0.4 parts of methyltriethoxysilane, 0.3 parts of antioxidant 1010, 0.2 parts of antioxidant, 0.3 parts of anti-ultraviolet agent , 3 parts of polycaprolactone, 2 parts of polyethylene wax, 2 parts of magnesium oxide, 8 parts of modified nano powder,

[0029] The modified nano-powder is prepared by the following method: after mixing calcium carbonate, lapis lazuli powder, and potassium feldspar powder in equal proportions, burning at 600-700°C for 4-5 hours, then grinding into nano-powder, mixing in Bis(dioctyloxypyrophosphate) ethylene titanate equivalent to 3-5% of the weight of the powder is stirred evenly, dried, and pulv...

Abstract

The invention discloses a plastic socket, a manufacturing method thereof and application of the plastic socket on an automobile. The manufacturing method mainly comprises the steps of: modifying nylon PA66, then adding the nylon PA66 as a raw material into a heated injection machine, and obtaining a final accepted product by setting the injection pressure, speeds, injection time and injection glue quantities of different sections of the injection machine and simultaneously setting that the final dwell pressure and pressure holding speed achieve the optimal injection technique. The socket disclosed by the invention is easy to mold in an injection manner, easy to demold, stable in machining technology, and high in qualification rate; the production efficiency is improved; the production cost is reduced; and the injected product socket is high in surface gloss, good in fire resistance, good in toughness, high in strength and stable in performance, and can be applied to the automobile.

Description

Background technique [0001] The invention relates to the field of engineering plastics, in particular to a plastic socket, its manufacturing method and its application in automobiles. Background technique [0002] With the development of the economy, the automobile industry is also developing rapidly. Most of the materials used in many parts of the automobile are engineering plastics, of which nylon is used in a large amount, and the requirements for the performance of nylon materials are getting higher and higher. While maintaining its own performance, it must be able to overcome its own shortcomings, so it needs to be modified. In the prior art, it is improved by adding additives such as tougheners and flame retardants to nylon. However, after various materials are mixed, the dispersibility of each component is poor during the blending process, the compatibility between each component is poor, the strength, toughness, and corrosion resistance are insufficient, the material...
