Abstract

The invention provides an environment-friendly circuit board cleaning agent. The cleaning agent is prepared from the following raw materials in parts by weight: 2-4 parts of sodium citrate, 5-10 parts of sodium laureth sulfate, 2-3 parts of coconut diethanolamide, 30-40 parts of ethanol, 4-5 parts of polyethylene glycol, 2-3 parts of petroleum sodium sulfonate, 2-3 parts of lignosulfonate, 4-5 parts of auxiliary and 100-120 parts of deionized water. The cleaning agent has the beneficial effects that the cleaning agent does not endanger the health of workers, is environment-friendly, non-combustible and non-explosive and has good safety because of using water and various low-toxicity reagents, is weakly acidic, enables the compatibility effects of various surfactants to be good, greatly improves the decontamination effect and the production efficiency, and reduces the cost; the auxiliary can form a protective film on the surface of the circuit board to isolate air to prevent water and other molecules in the air from corroding the circuit board; the cleaning agent is resistant to oxidation, prevents short circuit and is convenient for operation of the next preparation process.

Description

A kind of environmental-protection circuit board clean-out system and preparation method thereof

Technical field

The present invention relates to clean-out system field, relate in particular to a kind of environmental-protection circuit board clean-out system and preparation method thereof.

Background technology

Along with the high speed development of unicircuit, the volume of circuit card is more and more less, and electronic component is more and more less, and density is increasing.If the dirt dust of the inside does not clean up in making processes, likely can cause the problems such as short circuit, corrosion, affect the normal operation of circuit card.At present majority circuit plate sanitising agent is all made with organism, and cleaning effect is good, is difficult for causing the problems such as short circuit, corrosion, and still, organic compound not only cost is high, and contaminate environment, damage the ozone layer, harmful to HUMAN HEALTH.Also have minority waterborne cleaning agent, but cleaning performance is limited, has security risk, require further improvement formula, technique, to reach clean thorough, pollution-free, the object of corroding little, healthy, circuit safety, reducing costs.

Summary of the invention

The object of the present invention is to provide a kind of environmental-protection circuit board clean-out system and preparation method thereof, this clean-out system has advantages of clean thorough, environmental protection.

Technical scheme of the present invention is as follows:

A clean-out system, is characterized in that being made by the raw material of following weight part: Trisodium Citrate 2-4, laureth sodium sulfovinate 5-10, coconut oil diethanol amide 2-3, ethanol 30-40, polyoxyethylene glycol 4-5, petroleum sodium sulfonate 2-3, sulfonated lignin 2-3, auxiliary agent 4-5, deionized water 100-120;

Described auxiliary agent is made by the raw material of following weight part: Silane coupling reagent KH-570 2-3, phytic acid 1-2, n-BMA 3-4,2.4.6-tri-(dimethylamino methyl) phenol 1-2, phenylformic acid monoethanolamine 2-3, oxidation inhibitor 1035 1-2, ethanol 15-18; Preparation method mixes Silane coupling reagent KH-570, phytic acid, ethanol, is heated to 60-70 ℃, stirs after 20-30 minute, then adds other remaining component, is warming up to 80-85 ℃, stirs 30 -40 minutes, obtain.

The preparation method of described environmental-protection circuit board clean-out system, it is characterized in that comprising the following steps: deionized water, Trisodium Citrate, laureth sodium sulfovinate, coconut oil diethanol amide, ethanol, petroleum sodium sulfonate are mixed, under 800-1100 rev/min of stirring, speed with 6-8 ℃/minute is heated to 50-60 ℃, add other remaining components, continue to stir 15-20 minute, obtain.

Beneficial effect of the present invention

Clean-out system of the present invention has been used water and various low toxicity reagent, do not jeopardize workers ' health, environmental protection and also non-combustible, do not explode, security is good; This clean-out system is slightly acidic, makes the compatibility of various tensio-active agents effective, has greatly improved clean effect, has improved production efficiency, has reduced cost.Auxiliary agent of the present invention can form protective membrane at circuit board surface, and isolated air, prevents water and other molecule open circuit potential plates in atmosphere, and anti-oxidant, anti-short circuit, facilitates next step manufacture craft to carry out.
