Nano-silicon dioxide modified environment-friendly waterborne paint remover and preparation method thereof

Abstract

The invention discloses a nano-silicon dioxide modified environment-friendly waterborne paint remover and a preparation method thereof. The nano-silicon dioxide modified environment-friendly waterborne paint remover is prepared from the following raw materials in parts by weight: 1.2-1.4 parts of nanometer montmorillonite, 1.5-2 parts of a penetrating agent T, 42-46 parts of benzyl alcohol, 11-12 parts of acetone, 10-11 parts of hydrogen peroxide, 3-3.5 parts of methylcellulose, 2-2.4 parts of urotropine, 1.3-1.5 parts of dodecylbenzenesulfonic acid, 1.6-1.9 parts of microporous starch, 2.2-2.5 parts of microcrystalline wax, 0.8-1 part of tetrabutyl titanate, a proper amount of ammonia water, a proper amount of ethyl alcohol, 50-55 parts of water, 1.2-1.5 parts of boronic acid, 0.4-0.6 part of sodium dichloro isocyanurate and 0.9-1.3 parts of nano-silicon dioxide. With using of the boronic acid and the sodium dichloro isocyanurate, the nano-silicon dioxide modified environment-friendly waterborne paint remover has the bacterium resistance and the corrosion resistance, is good in permeability and promotes peeling of a paint film; and by using the nano-silicon dioxide, peeling is formed at an interface, the peeling speed is increased, secondary pollution is prevented, and metal corrosion is retarded.

Description

technical field [0001] The invention relates to the technical field of paint removers, in particular to a nano-silica modified environment-friendly water-based paint remover and a preparation method thereof. Background technique [0002] Traditional chlorinated alkanes supplemented with benzene-based paint strippers are highly toxic and highly polluting. Although they can efficiently remove the paint film on the substrate, they also cause great harm to the environment and operators. In recent years, it has been a research hotspot to develop a new type of low-pollution environment-friendly paint remover. The article "Research Progress of Environmentally Friendly Paint Strippers" briefly introduces the working principle and types of paint strippers, focuses on the composition of environmentally friendly paint strippers, and looks forward to the development trend of paint strippers in the future . [0003] Most of the traditional paint strippers use chlorinated hydrocarbons a...

Problems solved by technology

The article "A New Emulsion-type Paint Remover" introduced the specific preparation method of the emulsion-based paint remover, and obtained a paint remover with better performance, but there is still a big gap between the paint-removing effect and the oil-based paint remover. The volatilization of organic solvents will pollute the environment and need to be improved. It is also necessary to reduce the corrosion of the paint stripping surface and reduce interface pollution.
