an anti-fog agent

Abstract

The invention discloses an antifogging agent which comprises sodium silicate liquor, glycerol and pure water for sufficiently dissolving the sodium silicate liquor and glycerol, wherein the sodium silicate liquor, glycerol and water are mixed together, the concentration of the sodium silicate liquor is 15mg / L-25mg / L; the volume ratio of the sodium silicate liquor to the glycerol is (15-25):(3-7). After the technical scheme is adopted, the antifogging agent disclosed by the invention breaks through a component forming form of the conventional antifogging agent, and is prepared by mixing the 15mg / L-25mg / L sodium silicate liquor with the glycerol at a volume proportion of (65-85):(3-7), and adopting a proper amount of pure water for sufficiently dissolving the sodium silicate liquor and glycerol. Compared with the prior art, the antifogging agent disclosed by the invention at least has the following beneficial effects: the antifogging agent does not contain components which are toxic on a human body, is safe and sanitary; the antifogging effect is more remarkable; the light transmittance is high and antifogging requirements of a transparent panel can be achieved; the natural volatilization effect is good and the antifogging treatment efficiency is high; particularly, cracking of organic panel workpieces such as plastic is not caused, the workpieces are effectively protected, and the service lives of the workpieces are long.

Description

technical field [0001] The invention relates to the field of antifogging agents, in particular to an antifogging agent which can effectively prevent workpieces such as panels from cracking. Background technique [0002] Anti-fogging agents are some surfactants with hydrophilic groups, which can be oriented on the surface of plastic panels and other workpieces, with the hydrophobic groups facing inward and the hydrophilic groups facing outward, so that water can easily wet the plastic surface, and the condensed fine water droplets can spread rapidly Form an extremely thin water layer or condense into large water droplets and slide down the surface of the workpiece. [0003] The composition of the antifogging agent is well known. For example, the Chinese invention patent CN201310457501.8 discloses a glass antifogging agent, which includes the following components in parts by weight, 3-10 parts of dodecylbenzenesulfur, 120,000 basic 30-45 parts of sodium sulfate, 2-8 parts of ...
