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 paint remover field, relate to a kind of basic paint remover and preparation method thereof.
Background technology
In some five metals production plants, because technique needs, need protect workpiece, in order to avoid affect next procedure, so need carry out protection by paints and lacquers to it, road technique must be returned paint again after completing instantly; Also have in addition a kind of technique, because needs carry out a kind of decoration to workpiece, need japanning, and the defective products producing after japanning is done over again after needing to move back paint again, for this technique, be all to adopt acid depainting, and acid depainting use is more dangerous, easily cause personnel's injury.
Depainting is one of important procedure in the middle of surface treatment; various paint removers arise at the historic moment in recent years; traditional organic paint remover is mainly methylene dichloride type paint remover; and due to 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.
Current paint remover exists the larger use of toxicity dangerous, and volatilization is not comparatively fast durable, big for environment pollution so that complexity is processed in sewage discharge and cost is high.Therefore exploitation low toxicity, difficult volatilization, corrode that little depainting 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 basic paint remover, is comprised of following parts by weight of component: 10～15 parts, 30～40 parts, 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, 35 parts, 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 one in Natvosol, methylcellulose gum.
The preparation method of above-mentioned a kind of basic paint remover, comprises the steps: benzotriazole, phenylcarbinol to mix, and obtains A liquid; Xiang Shuizhong adds sodium hydroxide, alkylphenol polyoxyethylene, water soluble cellulose, toxilic acid two formicesters, polyoxyethylene glycol successively, mixes, and obtains B liquid; A liquid, B liquid are mixed, obtain basic paint remover.
Preferably, the method comprises the steps: benzotriazole, phenylcarbinol to mix, and obtains A liquid; Xiang Shuizhong adds sodium hydroxide, mixes, then adds alkylphenol polyoxyethylene, mixes, then adds water soluble cellulose, mixes, then adds toxilic acid two formicesters, mixes, then adds polyoxyethylene glycol, mixes to obtain B liquid; A liquid, B liquid are mixed, obtain basic paint remover.
The using method of basic paint remover of the present invention: basic paint remover is added to water and 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 extends, thereby effectively increases work efficiency, and has significantly 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
2.
