Abstract
The present invention relates to a new general efficient paint remover and a preparation method thereof. The paint remover is prepared in a mode that methylene chloride, methanol, formic acid, m-cresol, paraffin, a surfactant and a corrosion inhibitor are mixed accordingly to a specified proportion and react under certain conditions. The paint remover has the characteristics of high paint removing speed, favorable paint removing effects, wide range of application, less corrosion to base materials, incombustibility, low toxicity, etc.
Description
Technical field
The invention belongs to the paint remover technical field, relate to a kind of fast, efficient, safe paint remover and preparation method thereof.
Background technology
Object paint films such as aircraft, steamer and bridge, furniture are in the life-time service process; the erosion and the physical abuse that can be subjected to various corrosive mediums are destroyed; phenomenon such as aging, be full of cracks, peeling occur and come off; cause paint film to lose the protection decoration function; if application again then needs to remove old paint film.Remove old paint film, past attempts adopts the method for machinery, as rooting out etc. with scraper is manual, but this method not only wastes time and energy, and easily matrix surface is caused physical abuse, particularly more difficult to the parts of some geometrical shape more complicated, and the use of paint remover can address these problems easily, the particularly use of organic solvent type paint remover can fast and effeciently remove various old lacquers and base material not caused big infringement.In recent years, many different types of chemical strippers have appearred on the market, though they are more time saving and energy saving than mechanical removal methods, but also there are many limitation in they,, paint stripping rate limited as the depainting kind is slow, big to the ground corrosion, and in addition, these paint removers mostly contain benzene, ether equal solvent, inflammable, and toxicity is big.
Summary of the invention
The object of the present invention is to provide that a kind of paint stripping rate is fast, paint removing effect good, applied widely, slight to the ground corrosion, and evaporation rate is slow, does not fire, the paint remover of low toxicity.
The invention provides a kind of remover recipe, it comprises methylene dichloride, methyl alcohol, formic acid, meta-cresol, paraffin, tensio-active agent and inhibiter, and the concrete weight percent of each component is as follows:
Methylene dichloride: 70-75%
Methyl alcohol: 5-10%
Formic acid: 5-10%
Meta-cresol: 3-5%
Paraffin: 1-3%
Tensio-active agent: 1-3%
Inhibiter: 0.5-1%
Inhibiter among the present invention is amine, urea or nitrogen azole compounds.
The manufacture method of paint remover is among the present invention: methylene dichloride is packed in the reactor, add paraffin, stir fully, left standstill 5 minutes, add methyl alcohol, after mixing, add formic acid, meta-cresol again, add tensio-active agent and inhibiter afterwards, be heated to 60-80 ℃, fully stirring reaction is 1 hour, and cooling packing gets final product.
Paint remover provided by the invention has following characteristics:
1, paint stripping rate is fast, can remove paint film in 1-10 minute.
2, depainting efficient height, the depainting area reaches more than 95%.
3, applied widely, not only can remove paint films such as epoxy, phenolic aldehyde, vinylformic acid, can also remove paint films such as organosilicon, organic fluorine.
4, extremely slight to the base material corrosion.
5, do not fire hypotoxicity.
Embodiment
Embodiment 1: the methylene dichloride that takes by weighing 75 weight parts injects reactor, the paraffin that adds 2.5 weight parts, stir fully, left standstill 5 minutes, and added the methyl alcohol of 8 weight parts again, add the formic acid of 8 weight parts and the meta-cresol of 4 weight parts then, add the tensio-active agent of 2 weight parts and the amine of 0.5 weight part again, be heated to 35 ℃, fully stirring reaction is 1 hour, and the cooling back gets final product with container package.
Embodiment 2: get the methylene dichloride of 70 weight parts, and the paraffin of 2 weight parts, the methyl alcohol of 10 weight parts adds the formic acid of 10 weight parts then, and the meta-cresol of 5 weight parts adds the tensio-active agent of 2.5 weight parts and the urea of 0.5 weight part, and all the other are identical with example 1.
Embodiment 3: get the methylene dichloride of 72 weight parts, the paraffin of 2.5 weight parts, the methyl alcohol of 8 weight parts, the formic acid that adds 10 weight parts then, the meta-cresol of 5 weight parts adds the tensio-active agent of 2 weight parts and the nitrogen azole compounds of 0.5 weight part, and all the other are identical with example 1.
Can be that 1 grade phenolic aldehyde urethane paint film was removed after using this paint remover in 2-3 minute with sticking power, harmless to ground.
Can be that 1 grade Resins, epoxy paint film was removed after using this paint remover in 2-4 minute with sticking power, harmless to ground.
Can be that 1 grade organic fluorine self-drying paint film was removed after using this paint remover in 3-5 minute with sticking power, harmless to ground.
Claims (3)
1, a kind of paint remover is characterized in that by weight: methylene dichloride 70-75%, methyl alcohol 5-10%, formic acid 5-10%, meta-cresol 3-5%, paraffin 1-3%, tensio-active agent 1-3%, inhibiter 0.5-1%.
2, the manufacture method of the described paint remover of a kind of claim 1, be that methylene dichloride is packed in the reactor, add paraffin, stir fully, left standstill 5 minutes, add methyl alcohol, after mixing, add formic acid, meta-cresol again, add tensio-active agent and inhibiter afterwards, be heated to 60-80 ℃, fully stirring reaction is 1 hour, and cooling packing gets final product.
3, paint remover according to claim 1 is characterized in that inhibiter is the compound of amine, urea or nitrogen azoles.
