Abstract
The invention discloses an alkaline paint remover and a preparation method thereof. The alkaline paint remover comprises the following components in part by weight: 30 to 40 parts of sodium hydroxide, 20 to 30 parts of benzyl alcohol, 5 to 8 parts of water-soluble cellulose, 1 to 3 parts of alkylphenol polyoxyethylene, 1 to 3 parts of benzotriazole, 3 to 6 parts of dimethyl maleate, 1 to 3 parts of polyethylene glycol and 10 to 15 parts of water. The alkaline paint remover is low in cost and toxicity, high in paint removing speed and environment-friendly and sewage is easy to discharge and treat. Different raw materials, proportioning ratios and preparation processes are adopted, so that the alkaline paint remover is safely used, the paint removing effect is enhanced, the using period is prolonged, the working efficiency is effectively improved, and the production cost is obviously saved.
Description
Technical field
The invention belongs to the paint remover field, relate to a kind of basic paint remover and preparation method thereof.
Background technology
In some five metals production plants, because arts demand needs workpiece is protected, in order to avoid affect next procedure, so need it is carried out protection by paints and lacquers, must return lacquer again after road technique is finished instantly; Also have in addition a kind of technique, owing to need to carry out a kind of decoration to workpiece, need japanning, and the defective products that produces after the japanning is done over again after need moving back lacquer again, for this technique, all is to adopt acid depainting, and acid depainting usage comparison is dangerous, causes easily personnel's injury.
Depainting is one of important procedure in the middle of the surface treatment; various paint removers arise at the historic moment in recent years; traditional organic paint remover mainly is methylene dichloride type paint remover; and because both at home and abroad to the improving constantly of environmental protection requirement, traditional methylene dichloride type paint remover is just progressively replaced by the paint remover of low toxicity, low volatility.
Present paint remover exists the larger use of toxicity dangerous, and volatilization comparatively fast is not durable, and is big for environment pollution so that complexity is processed in sewage discharge and cost is high.So exploitation low toxicity, difficult volatilization, the little depainting of corrosion is fast, paint remover simple, relative environmental protection is processed in sewage discharge will become the trend of market development.
Summary of the invention
The object of the present invention is to provide a kind of basic paint remover and preparation method thereof.
For solving the problems of the technologies described above, adopt following technical scheme:
A kind of basic paint remover is comprised of following parts by weight of component: 10～15 parts in 30～40 parts in sodium hydroxide, 20～30 parts of phenylcarbinols, 5～8 parts of water soluble celluloses, 1～3 part of alkylphenol polyoxyethylene, 1～3 part of benzotriazole, toxilic acid two formicesters 3～6, polyoxyethylene glycol 1～3, water.
Preferably, this basic paint remover is comprised of following parts by weight of component: 12 parts in 35 parts in sodium hydroxide, 25 parts of phenylcarbinols, 6 parts of water soluble celluloses, 2 parts of alkylphenol polyoxyethylene, 2 parts of benzotriazoles, toxilic acid two formicesters 4, polyoxyethylene glycol 2, water.
Preferably, water soluble cellulose is at least a in Natvosol, the methylcellulose gum.
The preparation method of above-mentioned a kind of basic paint remover comprises the steps: benzotriazole, phenylcarbinol mixing are got A liquid; Xiang Shuizhong adds sodium hydroxide, alkylphenol polyoxyethylene, water soluble cellulose, toxilic acid two formicesters, polyoxyethylene glycol successively, and mixing gets B liquid; With A liquid, B liquid mixing, get basic paint remover.
Preferably, the method comprises the steps: benzotriazole, phenylcarbinol mixing are got A liquid; Xiang Shuizhong adds sodium hydroxide, and mixing adds alkylphenol polyoxyethylene again, and mixing adds water soluble cellulose again, and mixing adds toxilic acid two formicesters again, and mixing adds polyoxyethylene glycol again, and mixing gets B liquid; With A liquid, B liquid mixing, get basic paint remover.
The using method of basic paint remover of the present invention: basic paint remover is added water be mixed with 3～10%(quality) working fluid, 70～85 ℃ are soaked workpiece to be cleaned, and the depainting time is 1～10min.
The invention has the beneficial effects as follows:
Basic paint remover cost of the present invention is low, toxicity is low, paint stripping rate is fast, simple, environmental protection are processed in sewage discharge.The present invention has adopted different raw materials, proportioning and preparation technology, uses saferly, and paint removing effect strengthens, life cycle prolongs, thereby the Effective Raise working efficiency has significantly been saved production cost.Under equal conditions, use the depainting area of basic paint remover of the present invention can reach 8.5 m
2, and the depainting area of common paint remover is for being 6 m
