Description
Technical field
The invention belongs to industry cleaning link field, more particularly, to a kind of baking vanish paint removing composition and preparation method thereof and
Using.
Background technology
Due to baking vanish have it is bright in luster, without stagnant light, not fugitive color, it is personalized strong, can appoint with floor tile wall brick furniture fabrics
Anticipate fine and smooth collocation, scrubbing resistance, surface, non-sticky dirt, easily (resistance to) scouring the features such as.Therefore, present baking vanish has been applied to each
Field.But the error occurred in the aging or spraying process due to paint film is not up to standard so that this workpiece need reclaim and again
Spraying, it is therefore desirable to remove old paint film.The method of past generally use machinery, such as knife is scraped, Manual shovel is except this method is not
Only waste time and energy, and easily cause machinery to be, damage on collective surface, in this year, it is different that many kinds also occurs in the market
The paint stripper of type, although they are more time saving and energy saving than mechanical depainting, there are many limitations in them, as depainting species has
Limit, paint stripping rate are slow.Up to the present, the research of baking vanish paint stripper is related to also in the starting stage, and this is mainly due to roasting
The adhesive force of paint is especially strong, and common paint stripper is difficult removing.
Therefore, develop efficiently, and take into account safe, economic, processing conveniently, be provided simultaneously with preferably low to base material corrosion take off
It is one of current urgent need to solve the problem to paint agent, is had important practical significance.
The content of the invention
It is an object of the invention to according to deficiency of the prior art, there is provided a kind of baking vanish paint removing composition.It is described roasting
Paint paint removing composition has the advantages that, depainting power excellent performance low to base material corrosivity, post processing is easy, and paint stripping rate is fast.
Another object of the present invention is to provide the preparation method of above-mentioned baking vanish paint removing composition.
It is still another object of the present invention to provide above-mentioned baking vanish paint removing composition answering in baking vanish depainting cleaning agent is prepared
With.
The purpose of the present invention is achieved through the following technical solutions：
A kind of baking vanish paint removing composition, is made up of component as follows by mass percentage：
Urea 2.5 ~ 5%
Metasilicate pentahydrate sodium 1 ~ 3%
Butyl acetate 10 ~ 17%
Phenol 2 ~ 5%.
BTA 0 ~ 1%
Surplus is water.
In the baking vanish paint removing composition of the invention formed by urea, sodium metasilicate, butyl acetate, phenol, it can be penetrated into
Enter the interface that base material is connected with paint film, and the connection destroyed between base material and paint film, so that paint film is completely from matrix
Separation, and paint film is completely insoluble in this paint stripper, so as to obtain good paint removing effect.Simultaneously as paint film does not pass through
The mode of dissolving, but so that paint film completely disengages with matrix in a manner of monoblock comes off.So, can be easily by paint film
It is kept completely separate out from the paint-removing liquid of baking vanish paint removing composition composition, depainting combination liquid is recycled, and can be more
More preferable paint removing effect is obtained in the short time.
Composition is corrosion-free to matrix material integrally in neutrality, therefore so that paint stripper of the present invention is good in paint removing effect
Protect base material simultaneously.
Preferably, the baking vanish paint removing composition is made up of component as follows by mass percentage：
Urea 2.5 ~ 5%
Metasilicate pentahydrate sodium 1 ~ 3%
Butyl acetate 10 ~ 17%
Phenol 2 ~ 5%
BTA 0.5 ~ 1%
Surplus is water.
The addition of BTA can further lift paint removing effect.
More electedly, the baking vanish paint removing composition is made up of component as follows by mass percentage：
Urea 3.5 ~ 5%
Metasilicate pentahydrate sodium 1%
Butyl acetate 16%
Phenol 2 ~ 3.5%
BTA 0.5 ~ 1%
Surplus is water.
The preparation method of the baking vanish paint removing composition, comprises the following steps：Each component is well mixed and produces described bake
Paint paint removing composition.
Application of the described baking vanish paint removing composition in baking vanish depainting cleaning agent is prepared.
Preferably, the baking vanish is epoxy resin, polyurethane or acrylate, and polyflon is as Main Ingredients and Appearance
Baking vanish.
It is highly preferred that the baking vanish is the baking vanish of polyurethane or acrylate as Main Ingredients and Appearance.It is of the present invention
Baking vanish paint removing composition handles polyurethane or during acrylate, can it is at 5 minutes in can make coating and matrix complete completely
Separation；Being directed to the coating that epoxy resin, polyflon etc. are difficult to elute also has good elution effect.
Compared with prior art, the present invention has advantages below and beneficial effect：
Baking vanish paint removing composition cost provided by the present invention is cheap, definitely green, and pollution is few, and the depainting time is short, infiltration
Power is strong, can be kept completely separate completely coating and matrix in the short time is, and corrosion-free to matrix, and paint removing effect is strong, no dead angle
And residual, baking vanish paint removing composition provided by the invention are a kind of universal baking vanish paint removing compositions, be applicable to it is a variety of not
The depainting of congener baking vanish, technical support can be provided for the development of industrial cleaning agent.
