Problems solved by technology

[0003] The technical problem to be solved by the present invention: Aiming at the drawbacks of current glass antifogging agents, which are easy to be erased or dissolved after use, have poor washing resistance and short antifogging time, a kind of beeswax micro-nano emulsion and amphiphilic structure guar gum is provided. The method for preparing the wash-resistant glass anti-fogging agent is that the invention firstly emulsifies the beeswax, then mixes it with deionized water to prepare a beeswax micro-nano emulsion, and then utilizes guar gum to carry out graft modification with acetaldehyde, so that it has Amphiphilic structure, the amphiphilic structure guar gum and beeswax micro-nano emulsification are mixed, combined according to the hydrophilicity of the molecular end, the combined material is mixed with alkyl glucoside, nano-calcium carbonate, dipropylene glycol methyl ether and essence to prepare a wash-resistant Glass anti-fogging agent, the invention effectively solves the problems that the traditional glass anti-fogging agent is easy to be wiped off or easily washed and dissolved by water, has poor washing resistance, and has a short anti-fog time limit after use. Moreover, the preparation steps are simple, and the obtained glass anti-fog The agent has good washing resistance, is not easy to be wiped or dissolved after use, and can effectively prolong the anti-fog aging effect

Abstract

The invention discloses a preparation method of a rinsing-resistant glass antifogging agent, and belongs to the technical field of glass anti-fogging agent preparation. The preparation method comprises the following steps of firstly emulsifying beewax, then mixing the emulsified beewax with deionized water to prepare a beewax micro-nano emulsion, then carrying out graft modification with acetaldehyde for guar gum, so that the guar gum is of an amphiphilic structure, mixing the guar gum of the amphiphilic structure with the beewax micro-nano emulsion, combining according to the hydrophily of molecular terminals, mixing the combined substance with alkyl glycoside, nano calcium carbonate, dipropylene glycol monomethyl ether and essence, and thus preparing and obtaining the rinsing-resistant glass antifogging agent. According to the preparation method, the problem that a traditional glass antifogging agent is likely to erase or rinse and dissolve with water after being used, and is low in rinsing resistance and short in antifogging ageing is effectively solved, and the preparation steps are simple; and the obtained glass antifogging agent has relatively high rinsing resistance and is not likely to erase or dissolve after being used, so that the antifogging ageing can be effectively prolonged.

Description

technical field [0001] The invention relates to a preparation method of a washing-resistant glass antifogging agent, and belongs to the technical field of glass antifogging agent preparation. Background technique [0002] Fogging on the glass surface is the formation of a large number of fine water droplets on the glass surface, which diffuses the light shining on the glass and becomes opaque. Fogging on the glass surface will cause a lot of inconvenience to production and life. In rainy or humid weather, especially in winter, moisture is easy to condense on various glass products such as car windshields and rear view mirrors, which will block the driver's sight, often causing various accidents, directly affect personal safety. In order to solve the above-mentioned problems, glass anti-fog products have emerged as the times require, but they all have the disadvantages of requiring heating during preparation and requiring high production equipment, especially the problem of ...
