Description
Technical field
The invention belongs to surface of metal product processing technology field, and in particular to a kind of watery paint remover and its preparation side
Method.
Background technology
On the one hand the effect of coating is to provide base material certain protective action, is on the other hand the outer of beautification coated article
See.In actual life, under environmental activity and physical mechanical effect, with the extension coating of use time often occur it is local or
Large area fails, such as loss of gloss, come off, scratch, ground corrosion, or there is in coating preparation process such as tangerine peel, crackle, powder
The defects such as change, cause the appearance of defective work, this requires thoroughly to remove coating, then sprays again.Mechanical removal coating has
There is the low shortcoming of time-consuming, efficiency, complex-shaped parts are tended not to realize with the removal of coating, it is also possible to cause ground
The destruction such as scuffing.
Paint stripper, also known as paint remover or paint remover, refer to effectively take off using the interaction between solvent and solvent composition
Except the various substrate surface coverings such as metal, template, apparatus（Paint, coating etc.）A class compound.It efficiently solves machine
The problem of tool removes coating, can fast and effeciently remove the various old paints of substrate surface without causing big infringement to base material.
The purpose of depainting is to obtain good secondary coating performance.The depainting principle of paint stripper be by dissolving, permeating, be swelled,
The a series of physical such as reaction and stripping, chemical reaction are realized.In existing various paint strippers, using dichloromethane to be main de-
The paint removing effect for painting the paint stripper of component is best, and use is most extensive.But in this kind of paint stripper, phenol contained etc. other one
A little harmful substance, particularly dichloromethane consumptions in formula are very big, so that the volatility and toxicity of this kind of paint stripper
It is larger, it is heavier to human body and environmental hazard.
In recent years, although people have done many researchs, the usage amount of dichloromethane is reduced, paint remover products is tended to be low
Poison, but the also many negative effects of band, such as number of patent application CN201410540597.9, disclose that " a kind of metal is quick
Paint stripper ", its synthesis material is：Potassium chloride, dichloromethane, lime, methanol, polyglyceryl fatty acid ester, butyl cellosolve, methanol
Amine, methyl-triazole, isopropanol, hexone, amine salt, ethylene glycol monobutyl ether, cyclohexanone.The metal that the invention is proposed
Quick paint stripper, can quickly be dissolved to metal surface coating, quickly remove paint, while will not produce damage to body surface
Wound.But, although this method reduces the usage amount of dichloromethane in raw material aspect, so as to reduce it to a certain extent
Toxicity, but its substitute depainting ability is weaker, for traditional paint stripper, its paint stripping rate is substantially reduced.And make
With the adhesive force for simply having loosened lacquer painting and metal after the paint stripper, subsequently still need manually to be struck off, therefore its depainting is imitated
It is really unsatisfactory.
In recent years, for health and the growing interest of environment, existing paint stripper can not meet the use demand of people, base
In this, it is necessary to a kind of environment-friendly, safety of exploitation, and the production of the paint stripper with very fast paint stripping rate and higher paint removal efficiency
Product.
The content of the invention
Present invention mainly solves technical problem：It is not ideal enough for existing paint stripper paint removal efficiency and paint stripping rate, very
Difficult by obstinate remaining coat of paint or granule foreign, thoroughly removing is clean, and contains the class noxious material of phenol one in paint stripper, can be to behaviour
Making the defect that environment and workers ' health cause harm, there is provided a kind of watery paint remover and preparation method thereof.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
A kind of watery paint remover, is made up of following weight parts raw material：
30~40 parts of phenmethylols, 5~10 parts of diethylene glycol monobutyl ethers, 5~10 parts of ethylene glycol monobutyl ethers, 10~15 parts of acetone, 15
~25 parts of oxidants, 3~5 parts of accelerator, 3~5 parts of thickeners, 1~3 part of corrosion inhibiter, 0.5~2.0 part of surfactant, 20~
30 parts of deionized waters.
The oxidant is any one in potassium permanganate, Peracetic acid.
The accelerator is any one in formic acid, acetic acid, lactic acid.
The thickener is any one in methylcellulose, ethyl cellulose, sodium carboxymethylcellulose, polyvinyl alcohol
Kind.
The corrosion inhibiter is any one in BTA, thiocarbamide.
The surfactant is any one in OP-10, neopelex.
A kind of preparation method of watery paint remover, is concretely comprised the following steps：
S1. take phenmethylol, diethylene glycol monobutyl ether, ethylene glycol monobutyl ether, acetone and accelerator to add in beaker, stir,
Obtain mixed liquor 1；
S2. thickener, corrosion inhibiter, surfactant are sequentially added into mixed liquor 1,60~70 DEG C are heated to, stirring 20~
30min, obtains mixed liquor 2；
S3. oxidant is added into mixed liquor 2, is heated to 70~80 DEG C, stirred 15~20min, obtain mixture；
S4. deionized water is added into mixture, is stirred at 50~60 DEG C, obtains watery paint remover.
The beneficial effects of the invention are as follows：
（1）The present invention is good using solvability, not volatile, the strong phenmethylol of penetrating power, diethylene glycol monobutyl ether, ethylene glycol
Monobutyl ether is re-dubbed main solvent, in the macromolecular chain segment for penetrating into paint film or coating its can be made molten by the space of paint film molecule
Solution, or its macromolecular volume is increased and is produced internal stress, when the internal stress of generation increases to a certain extent, destroy paint film
The adhesion of coating macromolecular and base material, so that paint film or coating are separated from base material；
（2）The present invention, to paint film oxidation Decomposition, rolls the paint film after peroxidating using oxidant, accelerates in paint stripper
Solvent molecule is penetrated between paint film and base material, accelerates the paint stripping rate of paint stripper, while using compound additive to paint film
Emulsify, disperse, dissolving, helping and ooze and the infiltration to paint film, expansion character, realize to the decomposition of old paint film, dissolve and come off；
（3）Watery paint remover of the present invention, therefore, will not be to operating environment during preparation and use without noxious materials such as phenol
Caused harm with workers ' health.
