Detergent for soldering tin and preparation method of detergent

Abstract

The invention discloses detergent for soldering tin and a preparation method of the detergent. The detergent is prepared from the following components in parts by weight: 30-40 parts of isoparaffin, 6-12 parts of an organic modified medical stone dispersion liquid, 15-25 parts of a surfactant, 5-10 parts of a stabilizing agent, 3-10 parts of a saponifier, 20-30 parts of water as well as 3-5 parts of carboxymethyl chitosan oligosaccharide, 7-9 parts of water-soluble phosphorylated chitosan and / or 2-4 parts of an organosilicon quaternary ammonium salt, 3-8 parts of an epoxy quaternary ammonium salt, and 4-6 parts of an epoxy organosilicon quaternary ammonium salt. The invention further discloses a preparation method of the detergent for soldering tin. The detergent disclosed by the invention is rapid to volatilize, rapid to seep, free of corrosion on substrates and high in cleaning property, and can be applied to fields such as headset plug lines and plastic; the surface of a substrate cleaned by using the detergent is bright, the connection strength of soldering tin is not influenced, and the sound quality of a headset line is not affected; a semi-water washing process is adopted, soldering tin is washed with the detergent firstly and water secondly, an outstanding washing effect can be achieved, and the detergent is reasonable in process, low in cost and can be produced in a large scale.

Description

technical field [0001] The invention belongs to the technical field of cleaning agents, in particular to a cleaning agent for soldering tin and a preparation method thereof. Background technique [0002] In recent years, the electronics industry has developed rapidly, and various electronic products have also been popularized. High-end mobile phones, computers, notebooks, etc. are often equipped with their own brand earphones to meet consumers’ needs in terms of audio quality, aesthetics, durability, and quality. high demand. A high-quality headphone plug cable is very important for good contact, sound quality assurance and safety of the headphone, and its reliability and cleanliness will directly affect the quality of the headphone. During the welding process of the plug wire, rosin, solder, fingerprints, oil and other substances are likely to remain, which may easily cause poor contact of the earphone, no sound from the earphone, or noise, etc., which will affect the use ...

AI Technical Summary

Problems solved by technology

However, the cleaning effect of existing cleaning agents is limited, and the main raw materials of cleaning agents generally use trichlorethylene, dichloromethane, etc. Although this type of cleaning agent has a good cleaning effect, the raw materials used are highly toxic and dangerous, which is harmful to the operation. The health of workers is extremely harmful, especially the strong volatility of dichloromethane, which will seriously affect the health of workers when inhaled, especially in the conditions of poor operating environment and poor ventilation effect, occupational diseases are easy to occur

In addition, this type of cleaning agent also pollutes the environment very much. In order to carry out advanced treatment on it, the requirements for processing equipment and technology are relatively high, which increases the production cost of the enterprise.

[0004] Based on environmental considerations, people began to look for other alternatives. Since some monohydric alcohols, esters, and ketone solvents have lower boiling points, they gradually replaced Freon and other ODS cleaning agents. However, due to the low flash point of these solvents, they are extremely Easy to cause fire and explosion accidents

Therefore, people began to look for cleaning agents that are safe, stable, environmentally friendly, and do not damage the ozone layer. Water-based cleaning agents follow this trend and gradually become the focus of people's research. However, the cleaning effect of this type of cleaning agent is not good at present.
