Manufacturing method for pattern adding and bending glass

Abstract

The invention discloses a manufacturing method for pattern adding and bending glass. The manufacturing method comprise the following steps: (1) adding patterns: glass paint with high temperature is taken to add patterns on the glass, wherein the glass paint is prepared from the following materials: 11-12 parts of hydroxyethyl cellulose, 4-6 parts of talcum powder, 3-5 parts of alkali bismuth chloride, 5-6 parts of dissolving resin, 3-4 parts of butyl alcohol, 5-6 parts of butyl stearate, 2-4 parts of gloss oil, and 30-40 parts of water; the temperature of the glass paint is 500-600 DEG C; (2) bending: a hot bending glass machine is adopted; bending and forming are conducted on the pattern added glass at a hot bending temperature of 600-700 DEG C. According to the glass paint and the temperature, the glass paint can be attached to the glass well, and has excellent acidproof, alkaliproof and waterproof property; the paint is not peeled off when the glass paint is taken in secondary high-temperature heating; painting, coloring, and pattern adding can be conducted on unbent glass first quickly, then the bending is conducted, so that operational efficiency is improved; the product quality is promoted effectively; convenience is brought to glass processing and manufacturing.

Description

technical field [0001] The invention relates to the technology in the field of glass processing and manufacturing, in particular to a method for manufacturing patterned and bent glass. [0002] Background technique [0003] In the existing glass tempering process, flat glass with a thickness of 5mm-20mm passes through the low-temperature zone of the furnace body and enters the high-temperature zone in a complete set of processing equipment. Different heating times are determined according to different glass thicknesses, and then sent out of the furnace body for further processing in the air grille area. The tempering treatment of the air grid, the bending and deformation processing of the glass is to enter the bending and deformation area after the high temperature area in the furnace, open the heating tubes on both sides and put down the upper pressure bar, press the counterweight irons on both sides of the furnace body to the required position, and the deformed The glass ...

Problems solved by technology

[0005] In view of this, the present invention aims at the deficiencies existing in the prior art, and its main purpose is to provide a method for manufacturing bent glass with patterns, which can effectively solve the problem that the existing bent glass is bent first and then sprayed with colored patterns. There is a problem that it is difficult to spray, color and add patterns to the curved position of the glass, resulting in low efficiency and poor product quality.
