Problems solved by technology

[0005] In the prior art, the car signs should be treated with PVD due to processing needs. Before the PVD treatment, the car signs need to be cleaned with high precision. However, most of the existing cleaning agents with better cleaning effects have more foam and are difficult to remove. The foam of the cleaning agent will greatly affect the mechanical efficiency, production process and product performance during the production process. However, there is no particularly effective non-foaming cleaning agent product on the market. In order to meet the needs of low-foaming products, low-foaming cleaning is developed and applied. agent becomes more important

Abstract

The invention relates to the technical field of metal processing processes, and discloses a wire drawing process of an automobile mark. The wire drawing process comprises the following steps of S1, the wire drawing procedure and S2 the PVD surface treatment procedure. S2 further comprises the following steps of PVD pretreatment, wherein the automobile mark is cleaned through a cleaning agent, andtime ranges from 15 min to 25 min; secondly, baking, wherein the automobile mark is baked for 10-15 min at the vacuum furnace temperature ranging from 80 DEG C to 90 DEG C; thirdly, hanging up; fourthly, coating; and fifthly, hanging down. The cleaning agent in the first step comprises, by weight, 70-80 parts of polyethylene glycol octylphenol ether and a modifier. The modifier comprises 10-15 parts of methyl triethoxysilane. The wire drawing process has the following advantages and effects that oil dirt can be separated from the metal surface by means of polyethylene glycol octylphenol ether;and methyl triethoxysilane is grafted to polyethylene glycol octylphenol ether, the molecular weight of hydrophilic groups is increased, modified polyethylene glycol octylphenol ether can enter a liquid film more easily, and bubbles can be diffused more easily so as to be permeated and broken.

Description

technical field [0001] The invention relates to the technical field of metal processing technology, in particular to a wire drawing technology for automobile signs. Background technique [0002] The wire drawing process is a metal processing process. In metal pressure processing, the metal is forcibly passed through the mold under the action of external force, the metal cross-sectional area is compressed, and the technical processing method to obtain the required cross-sectional shape and size is called the metal wire drawing process. [0003] PVD, that is, physical vapor deposition, refers to the use of low-voltage, high-current arc discharge technology under vacuum conditions, using gas discharge to evaporate the target material and ionize both the evaporated material and the gas, and use the acceleration of the electric field to make The evaporated substance and its reaction products are deposited on the workpiece. Its function is to spray some particles with special pr...
