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 preferably acid and alkali-resistance and solvent nature, 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 come off, cause paint film to lose protection decoration function.Need with this understanding former coating removal to carry out application again.Conventional stripping method has mechanical or manual removal method, paint remover to remove method, combustion method, strong oxidizer removal method etc.These methods not only waste time and energy, and easily matrix surface are caused to physical abuse, 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, name is called the patent of invention of " paint remover of removing epoxy primer and polyurethane finish coating ", this patent relates to a kind of paint remover of removing epoxy primer and polyurethane finish coating, aim to provide a kind of low toxicity, potential of hydrogen is little, depainting efficiency is high, corrosion-free to metal substrate, paint remover that particularly can 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, 45% ~ 55% N-Methyl pyrrolidone and 15% ~ 25% pimelinketone are as main solvent, 8% ~ 12% methyl alcohol or ethanol are as solubility promoter, in 8% ~ 12% ethanolamines, any does promotor, and 8% ~ 12% ethylene glycol ethyl ether is as tensio-active agent and a small amount of thickening material and resistance 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 pollutionly, has controlled preferably the corrosive nature to matrix.Can promptly remove stainless steel subassembly surface epoxy primer and polyurethane paint coating.
Removing epoxy primer in above-mentioned patent and the paint remover of polyurethane finish coating exist and are only applicable to remove epoxy primer and polyurethane finish coating, and the high problem of volatility.
Summary of the invention
The present invention is intended to solve paint remover existence of the prior art and is only applicable to remove epoxy primer and polyurethane finish coating, and the high problem of volatility, and a kind of paint remover is provided, and makes its range of application wider, and volatility is low.
To achieve these goals, concrete technical scheme of the present invention is as follows:
