Problems solved by technology

At present, the cleaning of these electronic industrial components on the market mostly uses chemical reagents that pollute the environment, which not only harms the health of operators but also causes great damage to the environment.
There are many brands of common cleaning agents such as water-based cleaning agents with different effects, and more importantly, they have a greater impact on the electronic components themselves; although common organic cleaning agents have better cleaning effects, the reagents themselves are more toxic

Embodiment 1

[0015] Formula composition and percentage by weight are:

[0016] Hexane: 40%,

[0017] Cyclohexane: 12%,

[0018] Acetone: 25%,

[0019] Butanediol: 7%,

[0020] Ethanol: 16%.

[0021] Mix the above ingredients according to the weight percentage, add ethanol and hexane to the reaction kettle and mix for 3 minutes, then add cyclohexane, acetone and butanediol in succession, stir for 10 minutes, then let it stand for 20 minutes and open the valve for filling , and the preparation is complete. Applying this cleaning agent to precision circuit boards, such as the cleaning of computer memory, has a good effect.

Abstract

The invention belongs to the cleaning technical field of the electronic industry, particularly relating to a cleaning agent for the electronic industry, a preparation method and applications thereof. The cleaning agent for the electronic industry consists of the following components by weight percent: 40-50% of hexane, 10-20% of cyclohexane, 20-30% of acetone, 5-10% of butanediol and 10-20% of ethanol. The invention comprises the hexane, the cyclohexane, the acetone, the butanediol and the ethanol, wherein the hexane and the cyclohexane have a deoiling function, the acetone has a cleaning function, the butanediol has the function of softening oil stains on metal surfaces, and the ethanol has the assistant oil strains removal function. The cleaning agent can be widely used for cleaning surface oil stains of the electronic industrial products, in particular for cleaning precise circuit boards and has good effects. The product of the invention has the advantages of simplicity and availability, low cost, relative environmental protection and the like.

Description

technical field [0001] The invention belongs to the technical field of electronic industry cleaning, and in particular relates to an electronic industry cleaning agent, a preparation method and an application thereof. Background technique [0002] With the rapid development of the electronics industry in recent years, the cleaning and maintenance of electronic components, and the recycling and treatment of waste parts in the future are not only related to production costs, but also related to environmental protection and the health of operators. At present, the cleaning of these electronic industrial components on the market mostly uses chemical reagents that pollute the environment, which not only harms the health of operators, but also causes great damage to the environment. There are many brands of common cleaning agents such as water-based cleaning agents, with different effects, and more importantly, they have a greater impact on the electronic components themselves; al...
