Background technology
With the rapid development of electronics industry, the composition that destruction is produced to environment, industry are contained in conventional clean agent
Increasingly stricter policy requirements are faced with cleaning agent industry.The most key is for environmental protection, and ODS cleaning agents will be by
Eliminate comprehensively.ODS refers to CFC-113, three kinds of cleaning agents of TCA, CTC (carbon tetrachloride) in cleaning industry.It is clear in accurate industry
Wash and clothes dry-cleaning etc. civilian cleaning field, the use of ODS cleaning agents and cleaning equipment is very universal, is almost related to all works
Industry field.At present, halogen-containing scaling powder volatilizes halogen-containing smog in welding, and body and environment can be damaged,
And hydracid is generated after this smog water suction, electronic product parts can be caused to fail.The printed circuit board (PCB) (PCB) of postwelding, if any
The free halogen of residual, surface insulation resistance can be caused to decline, and electrochemical migration can be accelerated.Therefore, some governments in the world
Tissue and non-government organization start to promote disabling halogen.In view of the situation, Electronic products manufacturing company all proposes to use Halogen
The requirement of type cleaning agent.

Scaling powder remaining on wiring board has fabulous effect in industry, and its cleaning speed is fast, and evaporation rate is moderate, and nontoxic, to people
The environmentally friendly halogen free environment-friendly cleaning agent of body.
The technical problem of the present invention is solved by the following technical programs.
A kind of halogen free environment-friendly cleaning agent, is made up of following substances：C9-C12The weight proportion of isoparaffin is 5~10%, is removed
The weight proportion of finish is 1~8%, and the weight proportion of glycol ether is 5~12%, the weight proportion of nonionic surfactant
For 1~5%, surplus is alkylol.
Specific preparation method：Solvent is first added in the reactor with agitator, is added under normal temperature by said ratio each
Kind raw material, after start is stirred 30 minutes, make it well mixed, stir to clarify transparent, standing, as stopping stirring, this hair
A kind of bright environment-protective halogen-free cleaning agent.
Optionally, the C9-C12Isoparaffin is Isopars, nonane, octane, one or both of cycloalkane
Mixture above.Several materials that example is stated all are the conventional materials in derusting oil, there is preferable dissolution to residue.
Optionally, described degreaser is agent for carbon hydrogen detergent.Agent for carbon hydrogen detergent is that extracted from oil a kind of is special steady
Determine agent, wherein helping weldering resin and water-based cutting oil as cleaning electronics, can effectively clean entrapped contaminants.
Optionally, described glycol ether is glycol propyl ether, propylene-glycol ethyl ether, propylene glycol propyl ether, propandiol butyl ether, third
Mixture more than one or both of glycol isobutyl ether, dipropylene glycol methyl ether, dipropylene.Glycol ether can be with
Water, alcohol, ketone, ether, ester, aromatic hydrocarbons, aliphatic hydrocarbon etc. are miscible, and can dissolve polymorphic type high polymer.
Optionally, described surfactant is amine oxide, one kind or their mixture in ethoxylation alcohol groups.
Optionally, described alkylol is methanol, absolute ethyl alcohol, mixture more than one or both of isopropanol,
Alkylol has very strong solvability, is the solvent of cleaning agent.
The beneficial effects of the invention are as follows：
This halogen free environment-friendly cleaning agent has fabulous cleansing power to scaling powder remaining on wiring board in electronics industry, clearly
It is fast to wash speed, evaporation rate is moderate, and nontoxic, Halogen, has no irritating odor, and to human body fanout free region, plate face will not after cleaning
Turn white, no washmarking print.It is pollution-free to atmospheric environment.It is a kind of high cleaning capability, the cleaning agent of high-environmental.
