The paint remover disclosed by the invention can be used for professionally removing acrylic paint, has the advantages of high paint removal speed, favorable effect, slight corrosion to the substrate, simple raw materials, low cost and simple preparation method, and is suitable for large-scale production.
Description
Technical field
The invention belongs to the paint remover technical field, relate in particular to a kind of paint remover of sloughing acrylic paint specially.
Background technology
Acrylic paint has excellent performance and is widely used in every field; Like metal; Bridge, electrical equipment surface etc.; And these objects are in the life-time service process; Can receive the erosion and the physical disturbance of various corrosive mediums, phenomenon such as aging, be full of cracks, peeling occur and come off causes paint film to lose the protection decoration function; If application again then need be removed old paint film.Removing old paint film has and adopts mechanical means; Use paint remover to shell lacquer now mostly; But the paint remover function is commonplace on the market at present; Can be used for sloughing various paint; But slough effect is not fine; If therefore the paint remover of specialty is arranged, can slough paint targetedly efficiently, will become the demand in market.
Summary of the invention
In order to overcome above-mentioned deficiency, technical problem to be solved provides the efficient paint remover that a kind of specialty is sloughed acrylic paint just in the present invention.
For solving the problems of the technologies described above, the technical scheme that the present invention adopted is following:
A kind of paint remover, it comprises the component of following weight percent proportioning: methylene dichloride: 60%～80%, formic acid: 10%～20%, ethanol: 5%～15%, methyl alcohol: 3%～8%.
Wherein, preferably, said paint remover comprises the component of following weight percent proportioning: methylene dichloride: 65%～75%, and formic acid: 10%～20%, ethanol: 8%～12%, methyl alcohol: 3%～8%.
Wherein, further preferably, said paint remover comprises the component of following weight percent proportioning: methylene dichloride: 70%, and formic acid: 15%, ethanol: 10%, methyl alcohol: 5%.
Beneficial effect: paint remover of the present invention can be used for specialty and sloughs acrylic paint, and paint stripping rate is fast, effective, and slight to the ground corrosion; Raw material is simple, with low cost, and making method is simple, is fit to scale operation.
