Description
Technical field
The invention belongs to cleaning agent technical fields, and in particular to a kind of environment-friendly type paint cleaning agent.
Background technique
Organic coating imparts the color of the various beauties of engineering plastic parts, but perplex recycling industry is the coating
Removal, only by after coating removal, application value just can be promoted effectively, be developed as a result, for removing engineering surface
The cleaning agent of coating is of great significance.With the rapid development of market economy, various paint advertisements are seen everywhere.But due to length
Phase wind, rain beat, solarization, and paint advertisement picture will gradually appear mottled, damage phenomenon, had not only influenced the effect of publicity but also had influenced city
Hold.If with the method for paint covering, effect is poor；If the method reparation manually struck off, large labor intensity are scraped
Dust is flown upward with the wind, is polluted environment, is influenced workers ' health.In order to change this situation, it is necessary to find better method.City at present
Common paint cleaning agent is generally divided into organic and inorganic dual-purpose on field, and organic washing agent is generally by alcohols, aromatic hydrocarbons, ketone and ether
Class equal solvent is composed, and volatility is higher and inflammable and explosive and is more toxic, and inorganic mostly based on soda acid, corrosivity
By force, cleaning speed is slow and effect is bad, and most common is to use neopelex for surfactant, is
Anionic surfactant, since its production cost is low, performance is good and nontoxic and be widely used.Cleaning agent master on the market
If removing for taking off for coating for metal surfaces, this kind of cleaning agent is according to polarity rule of similarity, solvation principle, solubility parameter
Principle is designed, and generally selection benzene, hydrocarbon, ketone are as host agent, especially using chloroform and methylene chloride as the hydrocarbon of host agent
Class excellent., there is following two aspect in the shortcomings that technical solution：First is that engineering plastics substrate is not suitable for, because of its host agent pair
The swelling of engineering plastics and solvability are very strong, such as engineering plastics can dissolve quickly in methylene chloride cleaning agent；Second is that this
Class host agent has stronger toxicity, such as European Union is forbidden to use methylene chloride cleaning agent in plain text.Also there is a small amount of use at present
In the cleaning agent of plastic basis material surface covering, mainly two class of organic solvent type and emulsion-type.These cleaning agents are mostly pure organic
Solvent, water-soluble formula is few, at high cost, volatile, and needs to heat when depainting, is generally handled at 60 DEG C or more,
It is unable to satisfy the needs of room temperature depainting.
Summary of the invention
The technical problems to be solved by the invention：For in currently available technology paint cleaning agent paint removing effect it is poor, to ring
Larger problem is polluted in border, provides a kind of environment-friendly type paint cleaning agent.
In order to solve the above technical problems, the present invention is using technical solution as described below：
A kind of environment-friendly type paint cleaning agent, which is characterized in that be made of the raw material of following parts by weight：Surfactant 25~40
Part, 15~20 parts of butyl, 5~10 parts of triethanolamine, 10~15 parts of detergent, 10~25 parts of deionized water.
The surfactant is neopelex, chelating agent, fatty alcohol polyoxyethylene ether, according to weight ratio 6
~12：3~8：5~10 compound.
The detergent is compound glycol ether, ethyl cellulose, paraffin by weight 2~4：1~3：2~6 modulation.
The chelating agent preparation method is：Polyacrylamide solution is taken, polyacrylamide solution volume is added in water bath with thermostatic control
Sulfanilamide (SN), formaldehyde is added after adjusting temperature in 6~10% sodium hydroxide solution, stirring, and weight is respectively polyacrylamide solution
3~4% and 2~3%, product chelating agent is obtained after reaction.
The compound glycol ether preparation method is：By weight 1~1.5：0.9~1.6 takes ethylene oxide, phenol, adds
Thermal agitation, is added sodium hydroxide, 8~9% methacrylic acid of phenol weight of phenol weight 10%, and concussion obtains compound second after cooling
Glycol ethers.
The paraffin is chlorinated paraffin.
In the chelating agent preparation method, first step water bath with thermostatic control temperature is 80 DEG C, and it is 60 DEG C that second step, which adjusts temperature,.This
Invention is compared with other methods, and advantageous effects are：
（1）The surfactant that the present invention uses presses one by neopelex, chelating agent, fatty alcohol polyoxyethylene ether
Certainty ratio compounds.Neopelex is anionic surfactant, since its production cost is low, performance is good and
It is nontoxic and be widely used, but it has the shortcomings that resistance to hard water is poor, it is certain irritating to have to skin；Fatty alcohol polyoxyethylene ether
For nonionic surfactant, the problem of it is irritating to the skin can be improved by being used in compounding with neopelex.This hair
The bright chelating agent prepared using polyacrylamide, sulfanilamide (SN), formaldehyde, main functional group N-C-S, C=S can be in wider temperature
Heavy-metal ion removal in range, destroying paint structure makes its cracking, falls off.
The present invention, which is reacted using phenol with ethylene oxide, sodium hydroxide, methacrylic acid, is made compound glycol ether, improves
The penetrating power of cleaning agent, and be known as fabulous dissolubility to the ethyl cellulose in detergent, be suitable for metal, ceramics,
All kinds of surface paint cleanings such as glass, plastics, processing substrate surface coating required time are short；The paraffin being wherein added can slow down it
The precipitation of his component improves the hold capacity of cleaning agent.
Compared with traditional paint cleaning agent, the present invention, instead of noxious material methylene chloride, is subtracted using butyl
Lack the toxic action of paint cleaning agent itself, while having reduced the pollution to environment, belongs to Environment protection cleaning.
