Description
Technical field
The invention belongs to metal cleaning technique fields, particularly a kind of aqueous, environmental protective paint stripper and preparation method thereof.
Background technology
With advances in technology with the development of society, the environmental consciousness of people is more and more stronger, and the requirement to paint stripper is also got over
Come higher.Currently, there are still some problems for the development of China's paint stripper, and if dichloromethane toxicity is big, paint removing effect is not ideal enough,
Concentrated acid sulphur pollution is serious etc..The 612nd article of Germany technology specification (TRGS) limits the use of dichloromethane paint stripper always, with maximum
Reduce work risk to degree.In order to reduce solvent content, the de- painting product that can be used safely is developed, is contained with high solid
The amount method original with water-based system substitution, the environmental hazard brought its object is to reduce the use of solvent and strong acid, together
When meet and do not hinder substrate surface, be conducive to recoat, can long-time service, it is and applied widely.
Therefore, how to produce environmentally friendly efficient reusable watery paint remover will be as paint stripper
Developing direction, most of existing basic products, though there is good paint removal efficiency, to the corrosion loss of gloss of aluminum alloy surface.
The content of the invention
In order to solve prior art problem, the present invention provides a kind of aqueous, environmental protective paint stripper, has free from extraneous odour, few to volatilize
Object is reused after may filter that, the phenomenon that having good paint removing effect, and corrosion loss of gloss will not be caused to aluminum alloy surface, is protected
The glossiness of aluminum alloy surface is held.
To achieve the above object, technical solution provided by the present invention is：A kind of aqueous, environmental protective paint stripper, feature exist
In each raw material components and its mass fraction are in the aqueous, environmental protective paint stripper：25-35 parts of water；35-45 parts of benzyl alcohol；Second two
10-15 parts of alcohol phenylate；10-15 parts of butyl；5-15 parts of carboxyethyl thiosuccinic acid；The hydrogen peroxide 2-5 of 55% concentration
Part.
Preferably, each raw material components and its mass fraction are in the aqueous, environmental protective paint stripper：25 parts of water；Benzyl alcohol 45
Part；10 parts of ethylene glycol phenyl ether；10 parts of butyl；8 parts of carboxyethyl thiosuccinic acid；2 parts of the hydrogen peroxide of 55% concentration.
Preferably, each raw material components and its mass fraction are in the aqueous, environmental protective paint stripper：25 parts of water；Benzyl alcohol 35
Part；10 parts of ethylene glycol phenyl ether；10 parts of butyl；15 parts of carboxyethyl thiosuccinic acid；5 parts of the hydrogen peroxide of 55% concentration.
Preferably, each raw material components and its mass fraction are in the aqueous, environmental protective paint stripper：35 parts of water；Benzyl alcohol 35
Part；10 parts of ethylene glycol phenyl ether；10 parts of butyl；6 parts of carboxyethyl thiosuccinic acid；4 parts of the hydrogen peroxide of 55% concentration.
The present invention also provides a kind of preparation methods of above-mentioned aqueous, environmental protective paint stripper, comprise the following steps：By above each
The proportioning of component adds in the carboxyethyl thiosuccinic acid in the water, then stirs 3-7 minutes, adds benzyl alcohol, stir
It mixes 3-7 minutes, adds ethylene glycol phenyl ether and stir 3-7 minute, then add in butyl, stirring 8-12 minutes, finally,
The hydrogen peroxide for adding in 55% concentration at the uniform velocity stirs 8-12 minutes.
The present invention has the advantages that：
Aqueous, environmental protective paint stripper provided by the invention is compared with traditional paint stripper, has free from extraneous odour, few volatile matter can mistake
The phenomenon that being reused after filter, having good paint removing effect, and corrosion loss of gloss will not be caused to aluminum alloy surface maintains aluminium conjunction
The glossiness of gold surface.
Specific embodiment
With reference to specific embodiment, the invention will be further described：
Embodiment 1：A kind of preparation method of above-mentioned aqueous, environmental protective paint stripper, comprises the following steps：Add by mass fraction
Add various components, 8 parts of carboxyethyl thiosuccinic acids are added in 25 parts of the water, then stir 3-7 minutes, add
45 parts of benzyl alcohols stir 3-7 minutes, add 10 parts of ethylene glycol phenyl ethers and stir 3-7 minutes, then add in 10 parts of diethylene glycol fourths
Ether stirs 8-12 minutes, and finally, the hydrogen peroxide for adding in 2 part of 55% concentration at the uniform velocity stirs 8-12 minutes.
Embodiment 2：A kind of preparation method of above-mentioned aqueous, environmental protective paint stripper, comprises the following steps：Add by mass fraction
Add various components, 15 parts of carboxyethyl thiosuccinic acids are added in 25 parts of the water, then stir 3-7 minutes, then add
Enter 35 parts of benzyl alcohols, stir 3-7 minutes, add 10 parts of ethylene glycol phenyl ethers and stir 3-7 minutes, then add in 10 parts of diethylene glycols
Butyl ether stirs 8-12 minutes, and finally, the hydrogen peroxide for adding in 5 part of 55% concentration at the uniform velocity stirs 8-12 minutes.
