Description
Technical field
The present invention relates to a kind of paint remover, relate generally to a kind of O/w emulsion type paint remover of environmental protection.
Background technology
Paint film is through exposing to the open air for a long time, can occur wearing out, be full of cracks, peeling and phenomenon such as come off, and causes paint film to lose provide protection.Paint remover commonly used takes off depainting so that application is newly coated with lacquer.Mostly paint remover on the market is to come depainting with high volatility and to the deleterious chloro thing of ozonosphere, though effect is good operator and environment is had very big harm but up to the present.Also some paint remover will be used strong acid or highly basic, as NaOH, and the vitriol oil, ammoniacal liquor etc., to base material, operator and environment all have very big harm.The perhaps also good slightly paint remover of some Environmental compatibility, but need boiling heating or the like, improved operation easier for the application in the large-scale outdoor work environment.
In the last few years, people more and more paid attention to for environmental problem, and various Chemicals are had a lot of requirements about Environmental compatibility, as the existing GB restriction of the volatility of Chemicals.It is neutral that therefore a lot of scholars are devoted to research and development, and environmental protection is to the free from corrosion efficient paint remover in metallic surface.
Summary of the invention
For solve the paint remover toxicity that exists in the prior art big, shortcoming such as need heat when using, the invention provides a kind of paint stripper of oil emulsion-in-water, have that toxicity is low, normal temperature uses, do not damage the advantage that base material does not influence the secondary application.
Technical scheme of the present invention is a kind of paint stripper of oil emulsion-in-water, and component is, by weight percentage:
2%～20% nucleophilic monomer,
20%～60% macromole solvent,
3%～10% gamma-butyrolactone,
3%～15% alkyl diol butyl ether,
0.5%～3% tensio-active agent, wherein by quality than nonionic surface active agent: ionogenic surfactant is between 2: 3 to 3: 2,
2%～5% thickening material,
1.5%～4% inhibiter,
Surplus is a water.
Described nucleophilic monomer is any one or a few in hydrogen peroxide, ethyl acetate, acetone, methyl-sulphoxide, the carbonates.Described carbonates is meant propylene carbonate or methylcarbonate.Described macromole solvent is any one or a few the mixture in phenylcarbinol, methyl-phenoxide, N-Methyl pyrrolidone, the isophorone.Described alkyl diol butyl ether is meant butyl glycol ether, Diethylene Glycol butyl ether.Described nonionic surface active agent is any one or a few in octyl phenyl Soxylat A 25-7, Tween-60, the polyoxyethylenesorbitan sorbitan monooleate; Described ionogenic surfactant is any one or a few in sodium laurylsulfonate, Sodium dodecylbenzene sulfonate, sodium lauryl sulphate, the potassium oleate.Described thickening material is methylcellulose gum, Xylo-Mucine, polyvinyl alcohol, one or more in the sodium polyacrylate.Described inhibiter is any one in imidazoles, naphthenic acid imidazoline or the benzotriazole.
The core of remover recipe is the selection of suitable solvent.Test us through a large amount of explorations and find that general ketone and ester can dissolve Synolac and Polyurethane; Obtain stable O/w emulsion with water miscible thickening material and anion surfactant and the composite use of nonionogenic tenside again.For the depainting process, what work more is to be water base component, and the oil base component more helps the swelling paint film, the two is mixed into emulsion state can make the effect between paint remover and the paint film more even; Owing to be O/w emulsion, can not stay oil film after effect finishes simultaneously, be easy to application and newly coat with lacquer at substrate surface.
Water base component be meant can dissolve each other with water or in water the bigger component of solubleness, the oil base component is meant the very little even insoluble component of solubleness in water.The compound method of paint stripper of oil emulsion-in-water of the present invention is earlier with the water-soluble water solution A of making of water base component, and the oil base component is mixed into mixture B, mixture B is added in the solution A to mix then, adds thickening material and inhibiter at last again.This preparation order is very important, because all be the water-based matrix among the A, B is slowly added among the A to guarantee that the mixture that obtains is an O/w emulsion.The addition sequence of thickening material and inhibiter imidazoles also is the stable existence for mixture in addition, can the addition sequence of thickening material form stable emulsion to mixture and have a significant impact, and adds the molecule uniform distribution that thickening material will be difficult to make all size in the mixture too early; The inhibiter imidazoles has demulsification, and addition sequence is placed on final emulsion when having stablized.
Below detailed description by each component further describe the present invention.
Phenylcarbinol, carbonates, pyrrolidone and small molecules ester and ketone are the surface polarities with reference to paint film, the data of polymer molecule contact angle and each solvent molecule dipole moment are selected to be gone out, and the solvent of forgo high volatility and strong toxicity.Wherein the small molecules solvent is in order to infiltrate through as early as possible in the polymkeric substance paint film, and macromole solvent such as phenylcarbinol, and isophorone is then for can the swelling paint film.Macromole solvent and small molecules solvent can both be at stable existence under the effect of tensio-active agent and thickening material in the paint remover emulsions.Gamma-butyrolactone can be assisted macromole dissolution with solvents paint film, and the alkyl diol butyl ether is the solvent of paint, resin.For water base component and oil base component can be present in in the mixture by jointly stabilizing, need select suitable tensio-active agent for use, certainly, because the influence of selected polarity of solvent and HLB value is to select anion surfactant and the composite use of nonionogenic tenside for use among the present invention.Nonionic surface active agent is selected from the octyl phenyl Soxylat A 25-7, Tween-60, and polyoxyethylenesorbitan sorbitan monooleate selects one or more according to circumstances in these several nonionogenic tensides; Ionogenic surfactant is selected from sodium laurylsulfonate, Sodium dodecylbenzene sulfonate, and potassium oleate selects one or more according to circumstances in these several anion surfactants; The ratio of nonionic surface active agent and ionogenic surfactant is between 2: 3 to 3: 2, looks the variation of mixed solvent and makes adjustment; Total consumption of tensio-active agent is no more than 3%, the upper limit here is a practical upper limit, because it is very little to the depainting effectiveness affects to increase tensio-active agent, and lower consumption can make the paint remover mixture very unstable, the small molecules solvent is volatilization fast, and depainting efficient is just had a greatly reduced quality.
