Soda-lime glass frosting liquid and preparation method thereof

Abstract

The invention discloses a soda-lime glass frosting liquid, which comprises the following components by weight: 10-28 parts of a fluorine-containing inorganic salt; 0.1-10 parts of an alkali metal salt; 0.1-15 parts of an ammonium salt; 0.01-50 parts of a hydroxyl-containing organic matter; 0.01-20 parts of an acid substance; and 35-75 parts of water. The soda-lime glass frosting liquid is uniformand stable transparent liquid, does not have the problems of precipitation, precipitation, agglomeration and the like in the storage process, has favorable storage stability, can be directly used, omits the tedious operation of proportionally adding acid or adding water to prepare the liquid in the conventional frosting powder, cancels the heat-preservation curing procedure before use, therefore,the frosting liquid has the characteristics of convenient use and operation, high production efficiency, stable frosting effect and good storage stability, and the production efficiency of frosting treatment of soda-lime glass is remarkably improved. The invention also provides a preparation method of the soda-lime glass frosting liquid.

Description

technical field [0001] The invention relates to the technical field of glass surface treatment, in particular to a soda-lime glass frosting solution and a preparation method thereof. Background technique [0002] Soda-lime glass has the characteristics of high light transmittance, corrosion resistance, good mechanical properties, mature production technology, and low cost. It is widely used in household doors and windows, automobile windows and rearview mirrors, and building curtain walls. The specular reflection of strong light from glass can cause light pollution. The sun reflected by the glass curtain wall under the hot sun and the high beam of the car coming from behind is reflected by the rearview mirror of the car can easily cause serious interference to the driver's sight, and even cause sudden temporary blindness. It may cause traffic accidents and seriously threaten the safety of drivers, pedestrians and vehicles. The anti-glare treatment of soda-lime glass can mak...

Problems solved by technology

[0004] The current type of soda-lime glass frosting agents on the market is mainly frosting powder. Before use, the frosting powder needs to be mixed with water or liquid acids such as sulfuric acid and hydrochloric acid in a certain proportion, and then heat-preserved for 24h-48h before it can be used. The frosting treatment of soda-lime glass is not only cumbersome, but also the long-time aging process seriously affects the production efficiency

[0005] Patent CN105330166B discloses an environmentally friendly glass frosting solution. The initial content of fluoride in its formula is low. Since fluoride ions are consumed with the reaction between the agent and the glass, the fluoride ion content decreases greatly during use, which will inevitably lead to frosting. Unstable effect

[0006] Patent CN106746702B discloses a colored glass ultra-fine crystal anti-glare frosting liquid. The glass frosting liquid contains insoluble solid barium sulfate and calcium fluoride. During storage, the insoluble components are easy to precipitate to the bottom of the container, and the product is stable in storage Poor performance, and insoluble components will produce sediments such as agglomeration and agglomeration during long-term storage, and improper dispersion will easily lead to uneven frosting
