Description
Technical field
The present invention relates to paint remover technical field, be specifically related to a kind of environmentally-friepaint paint remover and preparation method thereof.
Background technology
Paint remover is the liquid mixed by hydrochloric ether, ketone, ester, alcohol, benzene homologues equal solvent.It is depend on dissolving, infiltration, swelling, peel off and the series of physical such as reaction, chemistry combined effect, thus destroy the space structure of paint film or the bonding force of paint film and base material, realizing solvent molecule penetrates in the molecule segment of paint film polymkeric substance, paint film dissolves, or polymer macromolecule volume increases generation internal stress, when internal stress is enough to the bounding force destroying paint film and base material, paint film has just been eliminated.
Along with the progress of science and technology and the development of society, the environmental consciousness of people is more and more stronger, and also more and more higher to the requirement of paint remover, the developing direction of following paint remover will be the research and development of environmentally friendly type, environmental paint remover.But traditional solvent stripper is mainly methylene dichloride type paint remover, this type of paint remover still based on organic reagent, organic reagent toxicity is large, volatile, easy firing and cost high, to bad environmental.Therefore, environment-friendly type solvent stripper becomes the emphasis instantly studied, it comprises watery paint remover, emulsion-type paint remover and low toxicity Low Volatile Coating Stripper, these three kinds of environmentally-friepaint paint remover are all large containing traditional toxicity, the organic solvent of high volatility chloro or other halogens, character is gentle, to base material and operator's fanout free region, and ambient operation, do not add the volatilization prevention compositions such as paraffin, do not affect the advantages such as the secondary application of workpiece.
Summary of the invention
It is high, applied widely, corrosion-free or corrodibility is little to matrix that the technical problem to be solved in the present invention is to provide a kind of paint removal efficiency, and high boiling point, good stability, to operator and environmental hazard is little, ambient operation, simple and easy to do environmentally-friepaint paint remover and preparation method thereof.
Present invention employs following technical scheme to reach foregoing invention object: a kind of environmentally-friepaint paint remover, being made up of the raw material of following weight part:
In order to obtain better invention effect, further setting is done to the present invention: described water soluble cellulose is one or both the mixture in Natvosol, methylcellulose gum.Because the Natvosol, the methylcellulose gum that add have the performances such as good thickening, bonding, emulsification, dispersion, maintenance moisture, each composition of making paint remover can be made to be mixed fully, to improve the paint removal efficiency of paint remover.
The further setting of the present invention: described tensio-active agent is one or both mixture of C12 fatty alcohol-polyoxyethylene ether, alkyl glycoside.By the tensio-active agent adopting C12 fatty alcohol-polyoxyethylene ether, alkyl glycoside to make paint remover, the paint remover biological degradation rate produced can be made greatly to improve, be conducive to the paint removal efficiency improving paint remover further, and make paint remover there is not any corrodibility to matrix.
The further setting of the present invention: described composite additive is the mixture of any three kinds in sodium malate, Sodium.alpha.-hydroxypropionate, sodium sarcosinate, sodium-acetate, Sunmorl N 60S.Greatly can increase the amalgamation of each composition by adding composite additive, improving the Combination of each composition further, and make the paint remover produced to operator and environmental hazard little.
The invention still further relates to the preparation method of a kind of environmentally-friepaint paint remover described above, preparation process is:
1) get the raw materials ready according to the raw material of following parts by weight: 20 ~ 25 parts, sodium hydroxide, ethyl acetate 10 ~ 15 parts, N-Methyl pyrrolidone 8 ~ 12 parts, water soluble cellulose 8 ~ 12 parts, 3 ~ 5 parts, tensio-active agent, composite additive 1 ~ 3 part, 40 ~ 45 parts, water;
2) sodium hydroxide step 1 got ready, ethyl acetate and suitable quantity of water join in reaction vessel A carries out uniform stirring and is mixed to get solution A;
3) N-Methyl pyrrolidone step 1 got ready, water soluble cellulose and suitable quantity of water join in reaction vessel B carries out uniform stirring and is mixed to get mixing solutions B;
4) solution A obtained respectively by step 2 and step 3 and solution B are poured in reaction vessel C successively, add tensio-active agent respectively simultaneously, composite additive is fully uniformly mixed, can final paint remover be obtained.
Beneficial effect of the present invention is: the present invention passes through sodium hydroxide, ethyl acetate as main solvent, paint removal efficiency is high, applied widely, ambient operation, simple and easy to do, corrosion-free or corrodibility is little to matrix, and boiling point can be improved by interpolation N-Methyl pyrrolidone, water soluble cellulose, stability is better and each composition is fully mixed, the paint remover biological degradation rate produced can be made greatly to improve by interpolation tensio-active agent, composite additive simultaneously, be conducive to the paint removal efficiency improving paint remover further, to operator and environmental hazard little.
