Adsorptive, flame-resistant and biodegradable temporary protective coating

Abstract

The invention provides an adsorptive, flame-resistant and biodegradable temporary protective coating, which comprises the following components in percentage by mass: 80.0 to 55.0 percent of deionized water, 15.0 to 25.0 percent of propanetriol, 0.5 to 2.0 percent of xanthan gum, 0 to 1.0 percent of sodium carboxymethylcellulose, 3.4 to 12 percent of dihydric alcohol or trihydric alcohol condensation compound, 1.0 to 4.5 percent of triacetic acid glyceride, and 0.1 to 0.5 percent of conserving agent. The temporary protective coating has the advantages that: the temporary protective coating canbe used through spray coating or brush coating, and conglutinates dust and over-sprayed paint particles floating in the air mainly through the combined action of the characteristics of isolation, adsorption and flame retardance so as to fulfill the aim of further purifying the air; the temporary protective coating can effectively prevent spraying lacquer mist from influencing the coating quality in the coating process, and can effectively improve the fireproof performance of a coating workshop; the temporary protective coating can be cleaned away by water washing to save labors; the temporaryprotective coating is dissolvable in water and is biodegradable; and the temporary protective coating can have an effective isolating protective effect on walls of the coating workshop, devices, pipelines and the like, and prolong the service life of the devices.

Description

Technical field: [0001] The invention relates to a temporary protective coating used in a painting workshop, in particular to an adsorption, flame-retardant and biodegradable temporary protective coating. (Product name: CHA-2820) Background technique: [0002] The air cleanliness of the painting workshop has a great impact on the quality of the painting. The main factors affecting the air cleanliness are the floating dust in the air and the oversprayed paint particles, and anti-static and fire safety are also the basic conditions that must be met in the painting process itself. . [0003] The use of protective film or temporary protective coating is a common protective technical measure at home and abroad. Different protective films have different functions. However, since the protective film needs to be pasted, most of the temporary protective coatings need to be brushed, which is inconvenient for construction. And it is inconvenient to remove, and the waste pollutes the ...

[0003] The use of protective film or temporary protective coating is a common protective technical measure at home and abroad. Different protective films have different functions. However, because the protective film needs to be pasted, most of the temporary protective coatings need to be brushed, and the construction is inconvenient.

Moreover, it is inconvenient to remove, and the waste pollutes the environment
