Embodiment 1
[0031] Embodiment 1 The technology of glass reshaping comprises the following steps:
[0032] (1) Preparation of coating: Take asbestos powder, silicone modified acrylate resin, methacryloxysilane, aluminosilicate and isopropanol respectively according to the proportioning ratio of 1:1.5:0.02:0.008:1. After the asbestos powder is ground, pass through a 600-mesh sieve, add methacryloxysilane and isopropanol to mix, put it in a high-speed disperser and disperse evenly for 8 minutes, add silicone modified acrylate resin and aluminosilicate to continue dispersing for 3 minutes , that is;
[0033] (2) Coating the surface of the glass blank with paint: use a sponge scraping tool or a brush to dip an appropriate amount of paint from top to bottom to coat with a coating thickness of 30μm, dry at 70°C for 30min, and then Dry at 100°C for 180min;
[0034] (3) Put the coated glass blank on the porcelain box, transport it into the heating zone in the softening furnace through the conve...
Embodiment 2
[0037] Embodiment 2 The technology of glass reshaping comprises the following steps:
[0038] (1) Preparation of coating: Take asbestos powder, silicone modified acrylate resin, methacryloyloxysilane, aluminosilicate and isopropanol respectively according to the proportioning ratio of 1:2:0.04:0.01:1.5. After the asbestos powder is ground, pass through a 600-mesh sieve, add methacryloxysilane and isopropanol to mix, put it in a high-speed disperser and disperse evenly for 8 minutes, add silicone modified acrylate resin and aluminosilicate to continue dispersing for 3 minutes , that is;
[0039] (2) Coating the surface of the glass blank with paint: use a sponge scraping tool or a brush to dip an appropriate amount of paint from top to bottom to coat with a coating thickness of 30μm, dry at 70°C for 30min, and then Dry at 100°C for 180mmin;
[0040](3) Put the coated glass blank on the porcelain box, transport it into the heating zone in the softening furnace through the con...
Embodiment 3
[0043] Embodiment 3 The technology of glass reshaping comprises the following steps:
[0044] (1) Preparation of coating: Take asbestos powder, silicone modified acrylate resin, methacryloyloxysilane, aluminosilicate and isopropanol respectively according to the proportioning ratio of 1:1.5:0.01:0.005:1. After the asbestos powder is ground, pass through a 600-mesh sieve, add methacryloxysilane and isopropanol to mix, put it in a high-speed disperser and disperse evenly for 8 minutes, add silicone modified acrylate resin and aluminosilicate to continue dispersing for 3 minutes , that is;
[0045] (2) Coating the surface of the glass blank with paint: use a sponge scraping tool or a brush to dip an appropriate amount of paint from top to bottom to coat with a coating thickness of 30μm, dry at 70°C for 30min, and then Dry at 100°C for 180mmin;
[0046] (3) Put the coated glass blank on the porcelain box, transport it into the heating zone in the softening furnace through the c...
