Peelable nano-grade decontamination coating

Abstract

The invention discloses a peelable nano-grade decontamination coating. According to mass volume percentages, the coating comprises but not limited to 1-30% of polyvinyl alcohol, 0.3-12% of nano-TiO2, 0.7-13% of a detergent, and at least one auxiliary agent with which polyvinyl alcohol can be dehydrated and a peelable polymer film can be formed. According to the peelable nano-grade decontamination coating provided by the invention, with the added TiO2, and with the effective combination of the auxiliary agents, the formed polymer film has the advantages of easy peeling, large tensile strength, and breakage preventing. A decontamination effect is substantial. In prior art, nuclear-contaminated solid surface and solid surfaces contaminated by some other substances cannot be washed by using large amount of water, and a decontamination amount is low. With the coating, the defects are solved. When the product is used in decontamination, a post-treatment garbage amount is low, and post-treatment cost is low. The characteristics are outstanding compared to those of prior art.

Description

technical field [0001] The invention relates to a decontamination paint and belongs to the field of material chemistry. Background technique [0002] At present, the decontamination coatings in the prior art mainly use water washing, high-pressure water washing, high-pressure steam cleaning, solvent cleaning, vacuum cleaning, and ultrasonic cleaning. Water contamination or other contaminants, or uneven damage to the substrate surface. In the prior art, there are also decontamination materials that can peel off the film, but the decontamination effect of this material is difficult to achieve the desired effect, and has no practical application value. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome existing defects and provide a peelable nanometer decontamination coating with good decontamination effect and convenient use; [0004] Another object of the present invention is to provide a method of applying the a...

Problems solved by technology

[0002] At present, the decontamination coatings in the prior art mainly use water washing, high-pressure water washing, high-pressure steam cleaning, solvent cleaning, vacuum cleaning, and ultrasonic cleaning, etc., The above methods are not only cumbersome, but also produce a large amount of water pollutants or other pollutants that need to be further treated after cleaning, or cause uneven damage to the substrate surface

There are also decontamination materials that can be peeled off in the prior art, but the decontamination effect of this material is difficult to achieve the desired effect, and has no practical application value
