Preparation method of household antifouling tempered glass

Abstract

The invention discloses a preparation method of household antifouling tempered glass. The method comprises the following steps: in the tempered glass cooling process, intermittently blowing to lower the glass temperature to 470-490 DEG C; then, carrying out ultrasonic cleaning on the glass, continuously blowing air and drying, and reducing the temperature of the glass to 150-180 DEG C; and respectively carrying out antifouling treatment on the two sides of the glass by adopting an antifouling coating, and finally cooling to room temperature by cold air. According to the method, ultrasonic cleaning is conducted on the glass after intermittent air blowing is conducted on the glass, and then antifouling treatment is conducted at the temperature of 150-180 DEG C, so that energy can be saved, and antifouling treatment is directly conducted at the temperature; and due to the fact that the main components of the antifouling coating are hydroxyl polyester resin and carboxyl-terminated polyester resin, a compact film structure can be formed, so that the protection effect on the glass is better, even if the glass bursts, the probability of splashing of glass fragments is lower, and the household use is safer.

Description

technical field [0001] The invention relates to the technical field of tempered glass, in particular to a preparation method of antifouling tempered glass for household use. Background technique [0002] Tempered glass (Tempered glass / Reinforced glass) belongs to safety glass. Tempered glass is actually a kind of prestressed glass. In order to improve the strength of glass, chemical or physical methods are usually used to form compressive stress on the glass surface. Wind pressure, cold and heat, impact, etc. [0003] For the production of tempered glass, the most likely problem is the phenomenon of self-explosion, that is, the phenomenon of self-rupture without the action of external mechanical force. The self-explosion of tempered glass can be called the "cancer" of the glass industry. At present, there is no way to solve this problem. a question. There are various reasons for the self-explosion of tempered glass. The main reason is that there are heterogeneous particle...

AI Technical Summary

Problems solved by technology

After tempering, some nickel sulfide stones will change in crystal state with time and environmental changes, resulting in an increase in volume, causing micro-cracks inside the glass, which may lead to self-explosion of the glass

[0004] After the self-explosion, although the glass shards do not have sharp edges and corners, they will still sputter, and there is still a greater risk for children in family use. Therefore, the present invention provides a low-risk preparation method of anti-fouling tempered glass for household use.
