Abstract
The invention discloses an oil paint stripping agent and a preparation method thereof. The oil paint stripping agent is composed of the following components in parts by weight: 10-20% of ethylene glycol monomethyl ether, 10-20% of ethylene glycol oxalate, 5-12% of dimethyl sulfoxide, 5-12% of N-methyl-2-pyrrolidone, 5-15% of ethanol, 5-15% of propylene glycol, 2-5% of polyacrylate, 2-4% of surfactant, 2-4% of odorant and 2-5% of thickening agent. The oil paint stripping agent provided by the invention has the following beneficial effects: firstly, various oil paint and coating on the surfaces of woods, metal, glass, optical fibers and various plastic materials can be removed within a short time; secondly, the oil paint stripping agent does not contain acid, alkaline, halohydrocarbon, methylbenzene and paraffin, therefore the surfaces of the materials cannot be damaged, and the human health cannot be endangered.
Description
Technical field
The present invention relates to a kind of paint stripper, particularly a kind of paint stripper of environment-protecting asepsis.
Background technology
Coating can be protected and decorative article, but in use, film can be damaged, or aging gradually, or needs to reprocess, upgrade due to aesthetic reason.For applications such as household electrical appliance, mechanical means, furniture, car and boat or when repairing, all need outmoded or damaged coating to remove, then spray.In air system, no matter civilian or military aircraft, for attractive in appearance and security needs, also needs regular depainting, and finishing is returned new.People often adopt a kind of chemical process, even if paint stripper.Paint remover speed is fast, and efficiency is high, removable coat type a wider range, is applicable to various paint and the exterior coatings such as alkyd, nitro, poly(urea formaldehyde) rubber-type ethene, epoxy, polyester, urethane.Good paint stripper can not only can remove the paint of timber, metal, glass, optical fiber and various frosting fast, but also should not contain bronsted lowry acids and bases bronsted lowry, not damage the surface of material.
Traditional paint stripper, although the effectiveness comparison removing paint is good, because of its usually containing acid, alkali, halohydrocarbon, toluene and paraffin.Paint stripper that is acid and alkalescence likely damages to some extent to the surface of material, is not thus best selection.Paraffin can be that material surface becomes very cunning, such paint film and material surface just well bond, thus reach the object of peeling painting, but paraffin is very not easily removed, the bonding of paint film and the material surface again whitewashed can be affected, therefore also there is very large defect.Paint stripper containing hydrochloric ether and toluene is effective, depainting is rapid, is applicable to various paint and coating, however modern medicine to think that hydrochloric ether can endanger healthy, toluene has potential carcinogenic risk, therefore neither be suitable for being added in paint stripper.
In sum, a kind of various paint and coating that can remove timber, metal, glass, optical fiber and multiple plastic material surface fast, and neither containing bronsted lowry acids and bases bronsted lowry, again not containing halohydrocarbon, toluene and paraffin, neither damaged material surface, harmless again, environmentally friendly paint stripper receives market widespread demand.
Summary of the invention
The object of the present invention is to provide a kind of various paint and the coating that can remove timber, metal, glass, optical fiber and multiple plastic material surface fast, and neither containing bronsted lowry acids and bases bronsted lowry, again not containing halohydrocarbon, toluene and paraffin, neither damaged material surface, harmless again, environmentally friendly paint stripper.
For achieving the above object, the present invention is made up of as following weight percent following material: ethylene glycol monomethyl ether 10 ~ 20%, EGA 10 ~ 20%, dimethyl sulfoxide (DMSO) 5 ~ 12%, METHYLPYRROLIDONE 5 ~ 12%, ethanol 5 ~ 15%, propylene glycol 5 ~ 15%, polyacrylic ester 2 ~ 5%, tensio-active agent 2 ~ 4%, taste-additive 2 ~ 4% and thickening material 2 ~ 5%.
Preferably, each compositions in weight percentage is respectively: ethylene glycol monomethyl ether 15%, EGA 20%, dimethyl sulfoxide (DMSO) 10%, METHYLPYRROLIDONE 10%, ethanol 14%, propylene glycol 15%, polyacrylic ester 5%, tensio-active agent 4%, taste-additive 3% and thickening material 4%.
Preferably, described taste-additive is limonene.
Preferably, described thickening material is hydroxylated cellulose.
Preferably, described tensio-active agent is sodium laurylsulfonate.
A kind of preparation method of paint stripper: dimethyl sulfoxide (DMSO), METHYLPYRROLIDONE and EGA are mixed in proportion and stir; Add ethanol in proportion subsequently and propylene glycol stirs; And then proportionally add polyacrylic ester and sodium laurylsulfonate stirs again; Last add limonene in proportion and hydroxylated cellulose stirs, obtain paint stripper of the present invention.
The invention has the beneficial effects as follows: various paint and the coating that timber, metal, glass, optical fiber and multiple plastic material surface 1, in the short period of time, can be removed.2, not containing acid, alkali, halohydrocarbon, toluene and paraffin, therefore both can not damaged material surperficial, can not be detrimental to health again.
