Description
Technical field
The invention belongs to field of fine chemical, and in particular to a kind of environment-friendly type low valent metal paint stripper and preparation method thereof.
Background technology
The object paint film such as aircraft, steamer and bridge, furniture is during life-time service; the erosion and mechanical damage destruction of various corrosive mediums can be subject to; and there is aging, cracking, peeling and the phenomenon such as come off; paint film is caused to lose protection decoration function; if will application again, need to remove old paint film.Traditional mechanical paint removal film method such as with scraper Manual shovel except etc., mechanical damage is easily caused to matrix surface, particularly more complicated to some geometries part is then more difficult.
But the use of paint stripper can easily solve these problems, the particularly use of organic solvent type paint stripper, can fast and effeciently remove various old paints and big infringement is not caused to base material.
In existing various paint strippers, for organic solvent type paint stripper, it is best with the paint removing effect of the paint stripper that dichloromethane is main depainting component, using most extensive, but contain organic and inorganic acid constituent in this kind of paint stripper, have very big corrosion failure effect to underlying metal material of painting.In addition, some other harmful substance, the particularly dichloromethane consumption in formula such as phenol for generally also containing in such chemical products is very big（Up to more than 60%, otherwise paint removal efficiency is significantly reduced general volume ratio）, so that the volatility and toxicity of this kind of paint stripper are larger, it is heavier to human body and environmental hazard.
A kind of Chinese patent 201510236889.8, it is proposed that automobile-used paint stripper and preparation method thereof, in terms of mass fraction, its each group distribution ratio is：1.3 portions of paraffin, 1～4 portion of ethanol, 2～7 portions of tetrahedronaphthalenes, 8～15 portions of butyl acetates, 58～83 portions of dichloromethane, 6～8 portions of ethylene glycol, 2～4 portions of triacetate fibers, 3～6 portions of sulfonated castor oils.The paint stripper provided by the invention can form mantle with enamelled coating, and secondary film and enamelled coating are easy to remove together.The used paint layer alkali liquor of residual is easily washed off very much, it is adaptable to is removed the used paint layer of automobile component, and is damaged less to automobile entirety lacquer painting.But dichloromethane, tetrahedronaphthalene used in its raw material have obvious volatility, and have extremely strong destructiveness to the respiratory system and nervous system of human body respectively.And the poisonous raw material such as dichloromethane is the core source of the paint stripper depainting ability, the input amount for reducing dichloromethane will certainly weaken its depainting ability.Therefore, there is conflict in the depainting ability of the paint stripper and the value of environmental protection, not meet requirement of the today's society to environmental protection material.
A kind of Chinese patent 201410540597.9, it is proposed that the quick paint stripper of metal.Its synthesis material is：Potassium chloride 8-11 parts, dichloromethane 3-9 parts, Calx 4-6 parts, methanol 5-9 parts, Polyglycerol ester of fatty acids 6-11 part, butyl cellosolve 5-7 parts, carbinolamine 4-6 parts, methyl-triazole 3-9 parts, isopropanol 4-10 parts, hexone 5-11 parts, amine salt 5-12 parts, ethylene glycol monobutyl ether 4-8 parts, Ketohexamethylene 2-7 parts.The quick paint stripper of metal proposed by the invention, can quickly be dissolved to metal surface coating, quickly be removed paint, while will not produce damage to body surface.Although the method reduces the usage amount of dichloromethane in raw material aspect, so as to reduce its toxicity to a certain extent, its succedaneum depainting ability is weaker, and for traditional paint stripper, its depainting performance is substantially reduced.The adhesive force of lacquer painting and metal is simply loosened after the paint stripper has been used, has subsequently been remained a need for manually being struck off, therefore its paint removing effect is unsatisfactory.
The content of the invention
For the deficiencies in the prior art, the invention provides a kind of environment-friendly type low valent metal paint stripper and preparation method thereof, the depainting preparation process green pollution-free, manufactured goods are to human body and environment non-hazardous, corrosion-free to metallic matrix.
The environment-friendly type low valent metal paint stripper that the present invention is provided is made up of the raw material of following weight portion：
Dodecylbenzene sodium sulfonate 20-25 parts, formic acid 10-15 parts, ethyl acetate 8-12 part, butyl acrylate 8-12 parts, triethanolamine 5-8 parts, ethylene glycol 10-15 parts, glycerol 10-15 parts, paraffin 0.5-2.0 parts, fatty alcohol-polyoxyethylene ether 2-4 parts, span-80 2-4 parts, methylcellulose 7-9 parts, paraffin 3-5 parts, deionized water 50-100 parts.
The preparation process of environment-friendly type low valent metal paint stripper that the present invention is provided is：
（1）The raw material of proper ratio is taken, the raw material in addition to glycerol is disposably added in the reactor with agitator, 60-70 DEG C is heated to, with 300-500 rev/min of rotating speed stirring reaction 1 ~ 2 hour.
（2）Stop heating stepses（1）In product, after being cooled to room temperature, add glycerol simultaneously with 800-1000 rev/min of rotating speed stirring 10-20 minutes.Then take out and seal up for safekeeping, obtain final product required metal paint remover.
The invention has the beneficial effects as follows：Environment-friendly type low valent metal paint stripper provided by the present invention has advantages below：（1）Green pollution-free, by rational proportioning raw materials, while paint stripper depainting ability is not reduced, reduces the toxicity of paint stripper so as to produces, will not produce any harm to environment and human body using process；（2）Depainting ability is strong, has extremely strong solvability to the enamelled coating of common metal surface, it is not necessary to excessive extra artificial treatment；（3）Corrosivity are little, friendly to metal, reduce the damage to depainting metal surface to the full extent, improve the value that metal recovery is utilized；（4）Cheap, composition is simple, and each to two kinds compositions play a part of its uniqueness, extremely simplify, no redundancy in material choice, is adapted to large scale investment and uses.
