Abstract
The invention relates to a paint remover and a preparation method thereof. The paint remover comprises the following materials in parts by weight: 60-80 parts of N-2 methyl pyrrolidone, 15-30 parts of alkyl phosphonic acid 2- ethyl hexyl ester monoethanolamine salt, 1-5 parts of ethylene glycol butyl ether, 5-10 parts of N, N-dimethyl acrylamide, 5-10 parts of cyclohexanone, 5-10 parts of isopropanol, 3-5 parts of diethanol amine, 2-4 parts of deionized water and 1-2 parts of OP-101. The paint remover disclosed by the invention solves problems that the paint remover in the prior air is only suitable for removing epoxy primer and a polyurethane finish coating and high in volatility, and can be used for conveniently removing various paint layers, so that a plurality of steps for re-coating are reduced; moreover, the paint remover is low in volatility, low in toxicity, high in stability and free from corrosivity.
Description
Technical field
The present invention relates to a kind of paint remover and preparation method thereof, belong to field of polymer material preparing technology.
Background technology
It is good that now widely used multiple priming paint and finish paint have good enamelled coating over-all properties, such as acid and alkali-resistance and solvent nature preferably, strong etc. with basal body binding force.But in life-time service process, because paint film can be subject to the impact of multiple inherence and externalities, there is aging, be full of cracks, peeling and the phenomenon such as to come off, cause paint film to lose protection decoration function.Namely former coating removal is needed to carry out application again with this understanding.Conventional stripping method has mechanical or manual removal method, paint remover removal method, combustion method, strong oxidizer removal method etc.These methods not only waste time and energy, and easily cause physical abuse to matrix surface, particularly more difficult to the parts of some geometrical shape more complicated.
It is CN102888141A that State Intellectual Property Office discloses a publication number in 2013.1.23, the patent of invention that name is called " removing the paint remover of epoxy primer and polyurethane finish coating ", this patent relates to a kind of paint remover removing epoxy primer and polyurethane finish coating, aim to provide a kind of low toxicity, potential of hydrogen is little, paint removal efficiency is high, corrosion-free to metal substrate, particularly can the paint remover of fast eliminating aircraft engine Profile For Compressor Stator straightening vanes lacquering.The present invention is achieved by following technical proposals: by weight percentage, said composition mainly contains, the N-Methyl pyrrolidone of 45% ~ 55% and the pimelinketone of 15% ~ 25% are as main solvent, the methyl alcohol of 8% ~ 12% or ethanol are as solubility promoter, in the ethanolamines of 8% ~ 12%, any one does promotor, and the ethylene glycol ethyl ether of 8% ~ 12% is as tensio-active agent and a small amount of thickening material and hinder volatilizer.The present invention is rapid to the inefficacy ability of enamelled coating surface bonding power, sticking power, solvent resistance, and toxicity is low, to metal, plastic basis material non-corrosiveness, produces free from environmental pollution, controls the corrosive nature to matrix preferably.Promptly can remove stainless steel subassembly surface epoxy primer and polyurethane paint coating.
The paint remover existence of the removing epoxy primer in above-mentioned patent and polyurethane finish coating is only applicable to remove epoxy primer and polyurethane finish coating, and the problem that volatility is high.
Summary of the invention
The present invention is intended to solve paint remover of the prior art existence and is only applicable to remove epoxy primer and polyurethane finish coating, and the problem that volatility is high, provide a kind of paint remover, make its range of application wider, volatility is low.
To achieve these goals, concrete technical scheme of the present invention is as follows:
A kind of paint remover, is characterized in that: comprise the following raw material according to weight parts:

A preparation method for paint remover, is characterized in that: comprise following processing step:
A, prior to adding N-2 methyl-2-pyrrolidone, pimelinketone, Virahol, diethanolamine successively in container, stirring and dissolving is even;
B, in the container in steps A, add alkylphosphonic acid carboxylic acid 2-ethylhexyl monoethanolamine salt, ethylene glycol monobutyl ether and N,N-DMAA again, stirring and dissolving is even;
C, in another container, add deionized water and OP-10 successively, stirring and dissolving is even;
D, under agitation, the solution prepared slowly is joined the container in steps A in step C;
E, fully stir miscible evenly after discharging can obtain paint remover of the present invention.
The Advantageous Effects that the present invention brings:
Paint remover of the present invention solves paint remover of the prior art existence and is only applicable to remove epoxy primer and polyurethane finish coating, and the problem that volatility is high, multiple enamelled coating can be made easily to come off, decrease multiple steps of again covering with paint, lacquer, colour wash, etc., and volatility is low, toxicity is low, and stability is high, non-corrosiveness.
