Problems solved by technology

[0006] However, the adhesion performance of the antistatic agent on the surface of the product also greatly affects its antistatic effect, and at the same time affects the stability of its antistatic ability. Therefore, how to improve the antistatic performance of the product while maintaining a stable antistatic ability is a technical problem.

Abstract

The invention relates to the technical field of static electricity prevention, in particular to an anti-static coating liquid. The coating liquid is prepared from the following raw materials in partsby weight: 10 to 20 percent of neutral silica sol, 20 to 30 parts of an anionic surfactant, 0.1 to 1 percent of an ampholytic surfactant, and the balance of water. The product is novel and unique; strong anti-static capacity can be achieved by applying the coating liquid to the back surface of RC phase paper; an anti-electricity coating has high water resistance and high adhesive force and does not fall off easily; the problems of product damage caused by static electricity, falling off of the anti-electricity coating caused by mechanical force and the like in producing, manufacturing, transporting and using processes of the RC phase paper are solved.

Description

technical field [0001] The invention relates to an antistatic coating liquid, in particular to an antistatic coating liquid applied to RC photographic paper. Background technique [0002] Due to the extreme hydrophobicity of the substrate used in photosensitive materials, it is very easy to absorb static charges. Therefore, during the process of coating, drying, cutting, transportation and later use, high-voltage static electricity is often generated due to friction, forming static spots. Usually positive charges appear as electrostatic spots and negative charges appear as dendrites. With the improvement of the sensitivity of photographic emulsion, the increase of coating speed, and the decrease of environmental humidity, the probability of static spots will increase, and in severe cases, a large number of products will be scrapped, causing great losses. RC high-gloss photo paper is a photo paper that is coated with double-sided plastic coated photo paper backing paper. RC ...
