Embodiment

[0011] A process for preparing tempered glass for a gas stove panel in this embodiment includes the following steps:

[0012] 1) In parts by weight, add 50 parts of water and 3 parts of emulsifier into the reactor, stir evenly, then add 25 parts of n-butyl acrylate, 5 parts of polymethylhydrogensiloxane, polydimethylsiloxane 15 parts, 20 parts of acrylic acid and 15 parts of polymethacrylate, stirred evenly, added 1.5 parts of initiator, and heated at 75°C for 4 hours to obtain a modified acrylic resin emulsion;

[0013] 2) In parts by weight, take modified acrylic resin emulsion, 40 parts of polyurethane resin, 8 parts of lithium sulfate, 5 parts of nano-titanium oxide, 12 parts of polyalphaolefin, 11 parts of white carbon black, 9 parts of polyethylene glycol and cure 6 parts of agent, stir and disperse evenly to obtain coating composition;

[0014] 3) Take the flat glass, cut, grind, wash and dry the flat glass, put it into the tempering furnace for heating, after reaching...

Abstract

The invention discloses a preparation process of tempered glass for a gas stove panel, which comprises the following steps: 1) preparing a modified acrylic resin emulsion; 2) preparing the modified acrylic resin emulsion, polyurethane resin, lithium sulfate, nano titanium oxide, and polyalphaolefin , white carbon black, polyethylene glycol and curing agent are mixed to obtain a coating composition; 3) Take flat glass and put it into a tempering furnace for heating. ℃, take it out, spray the coating composition evenly on the surface of the flat glass, and wait until it cools down to room temperature. The preparation method of tempered glass provided by the present invention is to modify the acrylic resin, adjust the coating composition with the modified acrylic resin as the base material, and improve the adhesion of the coating composition to the surface layer of the tempered glass, so that the tempered glass surface It has high flatness and also improves the surface stress of tempered glass.

Description

technical field [0001] The invention belongs to the field of casting technology, and in particular relates to a preparation process of tempered glass for a gas stove panel. Background technique [0002] Tempered glass, which belongs to safety glass, is 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. Enhance the glass's own wind pressure resistance, cold and heat resistance, impact resistance, etc. Contents of the invention [0003] In order to overcome the above-mentioned technical problems existing in the prior art, the object of the present invention is to provide a process for preparing tempered glass for gas cooker panels, which solves the problems of low surface flatness and low coating adhesion of the tempered glass. [0004] A preparation process of tempered glass for a gas stove panel provided by the present invention comprises the following ste...
