Abstract

The invention discloses an environment-friendly cleaning agent for the superficial paint on the metal surface. The cleaning agent is prepared from isoparaffin of C10-C12, organic ester compounds and plant extracted limonene. The cleaning agent can be used for effectively removing residual superficial paint, does not destroy a sprayed paint coat, does not hurt human bodies or influence the environment, and is suitable for most working situations.

Description

A kind of environment-friendly type metal surface floating paint clean-out system

Technical field

The invention provides a kind of environment-friendly type metal surface floating paint clean-out system, belong to cleaning technique field, metallic surface.

Background technology

Paint is that one firmly can cover object surface, play protection, decoration, mark and the chemical mixture coating of other special purposes.

At modern science and technology and industrial circle, the application of paint is more and more extensive.Due to the misoperation in construction process, often cause the situations such as overbrushing, holiday, by mistake painting and need again to do over again and be coated with again.Both add time cost like this, cause again the waste of material.

The clean-out system of the removal paint that existing market mainly uses mainly adopts toluene, dimethylbenzene, lacquer thinner, methylene dichloride, acetone, phenol etc., these clean-out systems not only have injury to human body, easily carcinogenic, easily cause occupational illness, and these rinse product can not carry out selective clearing to floating paint, the paint coated is produced to the shortcomings such as destruction.

Summary of the invention

For the defect that existing paint-removing class rinse product exists, the object of the invention is to be to provide a kind of effectively can remove unnecessary floating paint while do not damage the enamelled coating sprayed, and to human body without harm, on the environment-friendly type metal surface floating paint clean-out system of environment without impact.

In order to realize above-mentioned technical purpose, the invention provides a kind of environment-friendly type metal surface floating paint clean-out system, this clean-out system is made up of following mass percent component: C ₁₀~ C ₁₂isoparaffin 60 ~ 90%; Organic esters 5 ~ 30%; Plant extract type limonene 5 ~ 30%.

Preferred scheme, C ₁₀~ C ₁₂isoparaffin is by C ₁₀isoparaffin, C ₁₁isoparaffin and C ₁₂isoparaffin is 1:(1 ~ 4 in mass ratio): 1 composition.Preferred scheme adopts C ₁₀, C ₁₁and C ₁₂mixed type isoparaffin, C ₁₀isoparaffin has good evaporation rate, can improve the evaporation rate of clean-out system, but its flash-point is lower, and C ₁₂isoparaffin has higher flash-point, but its evaporation rate is relatively slow, and C ₁₁isoparaffin between, therefore adopts this mixture system, to reach the effect that volatilization is fast, flash-point is high; It is that normal paraffin can not be compared that isoparaffin has the advantages such as low smell and high flash point, so C ₁₀~ C ₁₂isoparaffin has not replaceability.

Preferred scheme, organic esters is at least one in tert.-butyl acetate, sec-butyl acetate, methylcarbonate, o-phthalic acid dibutyl ester and synthesis vegetable esters.

Preferred scheme, comprises at least one in 1,8-terpadiene, d-limonene and l-limonene in plant extract type limonene.

C of the present invention ₁₀~ C ₁₂isoparaffin, comprises C ₁₀isoparaffin, C ₁₁isoparaffin and C ₁₂isoparaffins etc. can directly be bought in the company such as american exxon, Japanese bright dipping; Organic esters, comprise tert.-butyl acetate, sec-butyl acetate, methylcarbonate, o-phthalic acid dibutyl ester and synthesis vegetable esters etc. can directly buy in the happy chemical industry of Jin Jin, bright morning the company such as chemical industry; Plant extract type limonene directly can be bought and contain chemical industry in Jiangxi state, the companies such as chemical industry are converged in Guangzhou.

Metallic surface of the present invention floating paint clean-out system preparation method: add reactor by formula rate, stir under the condition of normal temperature and pressure.

The using method of paint clean-out system is floated in metallic surface of the present invention:

(1) method of soaking and washing: directly workpiece to be washed is dipped into inside this solution and takes out after 10 ~ 30 minutes, dry with clean scouring pad, dry up or naturally dry afterwards;

(2) scrub method: dip this clean-out system with cleaning means such as brushes, then to needing the floating paint part removed to scrub, to be removed clean after, dry with clean scouring pad, dry up or naturally dry;

(3) hydro-peening method: this product is sprayed on professional 161# spray gun or other spray instrument the position needing cleaning, dried with clean scouring pad, dry up or naturally dry after 10 ~ 30 minutes.

Hinge structure, the Advantageous Effects that technical scheme of the present invention is brought:

1, the raw material adopted in cleaning agent formula of the present invention is by low toxicity or nontoxic raw material is composite forms, and to producing and using the body-stimulating of operator little, also has no adverse effects to environment;

2, can effectively select to remove unnecessary floating paint, and to the lacquer painting not damaged sprayed.

3, rinse product of the present invention has low smell, volatilization is fast, flash-point is high feature, is applicable to most operating mode.

Embodiment

Following examples are intended to further illustrate content of the present invention, instead of the protection domain of restriction the claims in the present invention.

Rinse product in following examples and comparative example, adds reactor by its formula rate by various raw material, stirs under the condition of normal temperature and pressure.

Rinse product in each embodiment and comparative example adopts the conventional method of scrubbing to carry out product performance checking: dip this clean-out system with cleaning means such as brushes, again to needing the floating paint part removed to scrub, to be removed clean after dry with clean scouring pad, dry up or naturally dry.
