Description

A kind of paint clean-out system and preparation method thereof

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 spissated paint clean-out system and preparation method thereof.

Background technology

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

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

Summary of the invention

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

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

Dipropylene glycol dme 15-25%;

N-Methyl pyrrolidone 25-40%;

Ethanol ammonia 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 to be carried out hybrid reaction by 20% dipropylene glycol dme, 25% N-Methyl pyrrolidone, 5.8% ethanol ammonia, 22% ethyl acetate, 7% fatty acid ester, 20% dimethyl ketone, 0.2% fruital essential oil and processed by massfraction by said clean-out system.

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

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

The first step takes by weighing dipropylene glycol dme, N-Methyl pyrrolidone, ethanol ammonia, 22% ethyl acetate, fatty acid ester, dimethyl ketone, fruital essential oil in proportion and packs in the airtight mixing vessel, under 30-40 ℃ of normal pressure, mixes one hour;

Second step added nanometer Margarita powder again, and stirring reaction is 30 minutes under the environmental stress of 2-5MPa, after mixing, carries out forming product behind the 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 concentrating, and is used for the removal fully that matrix (being generally crust) is coated paint, does not damage stromal surface.Add the part green solvent and the micro-nano green factor, make clean-out system environmental protection more, more efficient, dissolve peeling painting, coating more fast, wetting, emulsification, cleaning function are stronger, and stability is better, more helps the antiredeposition of dirt.

Specific embodiment

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

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

Wherein, fatty ester is that propylene glycol fatty acid ester is by lipid acid and 1,2 one Ucar 35 esterification reaction and get, and products therefrom is the mixture of monoesters and dibasic acid esters, can obtain the Ucar 35 mono fatty acid ester through short-path distillation again; Parts such as the flower of fruital essential oil through the plant of fruit fragrance, leaf, root, skin, stem, branch, fruit, seed; The oily mater that take to distill, method such as squeezing, extraction, absorption makes with characteristic perfume; In order to prolong its work-ing life; Let its effect keep for a long time; The long-acting natural phant lasting agent with sustained release performance that can also prepare through advanced person's high molecular nanometer microencapsulation technology at present, just industrial essence, the mask agent of using always in a kind of heavy chemicals field.

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