Description

A kind of preparation method who paints clean-out system

Technical field

The present invention relates to a kind of clean-out system, especially a kind of safety brute force, economical and efficient, energy-conserving and environment-protective, novel concentrated paint clean-out system and preparation method thereof.

Background technology

The illegal small advertisement sponsor of Chinese city, for making its small advertisement forever firm, is also retained on the buildingss such as city body of wall, road, lighting standard.Use bonding very firmly to paint and spray.Remove the large chronic disease that paint spraying advertisement has become Chinese city management.

China for a long time, generally adopts the improvement method of paint, coating covering, and the one, can not thoroughly remove, the 2nd, cause secondary pollution.Therefore be badly in need of inventing that a kind of power of removing is strong, safety and environmental protection, novel concentrated green painting clean-out system come beautifying urban environment thoroughly to solve city management chronic disease.

Summary of the invention

The present invention is directed to above-mentioned paint proposes a kind of technical problem safe brute force, economical and efficient, energy-conserving and environment-protective, novel concentrated paint clean-out system and preparation method thereof is provided.

This paint clean-out system is by dipropylene glycol dme, N-Methyl pyrrolidone, thanomin, ethyl acetate, fatty acid ester, dimethyl ketone and fruital essential oil, with the ratio of following quality percentage composition, to carry out hybrid reaction to make:

Dipropylene glycol dme 15-25%;

N-Methyl pyrrolidone 25-40%;

Thanomin 5-8%;

Ethyl acetate 20-30%;

Fatty acid ester 5-10%;

Dimethyl ketone 15-25%;

Fruital essential oil 0.2%.

Preferably, this clean-out system is to be carried out hybrid reaction and made by 20% dipropylene glycol dme, 25% N-Methyl pyrrolidone, 5.8% thanomin, 22% ethyl acetate, 7% fatty acid ester, 20% dimethyl ketone, 0.2% fruital essential oil by massfraction by described clean-out system.

Preferably, the nanometer Margarita powder that also adds 0.01-0.05% in described paint clean-out system.

The present invention also provides a kind of method of preparing above-mentioned paint clean-out system, and it comprises the steps:

The first step, takes dipropylene glycol dme, N-Methyl pyrrolidone, thanomin, 22% ethyl acetate, fatty acid ester, dimethyl ketone, fruital essential oil pack in airtight mixing vessel, under 30-40 ℃ of normal pressure, are uniformly mixed one hour in proportion;

Second step, then add nanometer Margarita powder, under the environmental stress of 2-5MPa, stirring reaction is 30 minutes, until carry out after mixing forming product after filtration, purification.

This technical scheme compared with prior art has following beneficial effect:

The cleansing power of this clean-out system is strong, noresidue, safety economy, energy-conserving and environment-protective, novel concentrated, and the removal completely of coating paint for matrix (being generally crust), does not damage stromal surface.Add part green solvent and the micro-nano green factor, make clean-out system environmental protection more, more efficient, dissolve more fast peeling painting, coating, wetting, emulsification, cleaning function are stronger, and stability is better, more contributes to the antiredeposition of dirt.

Specific embodiment

This paint clean-out system provided by the present invention, it is made with the ratio hybrid reaction of following quality percentage composition by dipropylene glycol dme, N-Methyl pyrrolidone, thanomin, ethyl acetate, fatty acid ester, dimethyl ketone and fruital essential oil:

Dipropylene glycol dme 15-25%; N-Methyl pyrrolidone 25-40%; Thanomin 5-8%; Ethyl acetate 20-30%; Fatty acid ester 5-10%; Dimethyl ketone 15-25%; Fruital essential oil 0.2%.

Wherein, fatty acid ester is that propylene glycol fatty acid ester is reacted and obtained by lipid acid and 1,2 one propylene glycol esterification, and products therefrom is the mixture of monoesters and dibasic acid esters, then can obtain propylene glycol mono fatty acid ester through molecular distillation; The parts such as the flower of the plant of fruital essential oil by fruit fragrance, leaf, root, skin, stem, branch, fruit, seed, the oily mater with characteristic perfume of taking the methods such as distillation, squeezing, extraction, absorption to make, in order to extend its work-ing life, allow its effect keep for a long time, the long-acting natural phant lasting agent with sustained release performance that can also prepare by advanced high molecular nanometer microencapsulation technology at present, industrial essence namely, conventional mask agent in a kind of heavy chemicals field.

Below with preparation 100KG paint clean-out system describe in detail this paint clean-out system provided by the present invention with and concrete preparation method.
