Problems solved by technology

[0002] The improvement of living standards and the deepening of the concept of environmental protection and energy saving have promoted the expansion of architectural decoration aesthetics and energy-saving materials. Flat glass is undoubtedly the best and most economical partition material, but it is cold, colorless, and especially poor in heat and sound insulation. Its performance greatly affects its application, and it is particularly important to improve the heat insulation and sound insulation performance of environmentally friendly decorative sliding door glass materials.

Embodiment 1

[0022] Prepare 1.5wt% KH-550γ-aminopropyltriethoxysilane coupling agent to make a solution; select a borosilicate with a heat transfer coefficient K value of 0.06w / m.k, an average diameter of 40μm, and a maximum diameter of 80μm Glass hollow glass microspheres are used as fillers for titanium dioxide; the hollow glass microspheres are dip-coated with a prepared silane coupling agent solution and dried at 60°C; the treated hollow glass microspheres are used to replace the original decorative glass with screen printing The proportion of titanium dioxide in the coating is 45%, add toluene and stir evenly, screen-print 2.2m×2.0m flat glass, and then enter the continuous tunnel furnace for baking treatment at 350°C; use the film thickness meter to monitor and control the film thickness to 60-80μm. The measured heat transfer coefficient is 5.4w / m.k, which is 10% lower than that of the original flat decorative glass.

Embodiment 2

[0024] Prepare 2.5wt% kH-551γ-aminopropyltrimethoxysilane coupling agent to make a solution; select borosilicate glass with a heat transfer coefficient K value of 0.065w / m.k, an average diameter of 40μm, and a maximum diameter of 85μm Hollow glass microspheres are used as fillers for titanium dioxide; the hollow glass microspheres are dip-coated with a prepared silane coupling agent solution and dried at 50°C; 50% of the treated hollow glass microspheres are used to replace the original decorative glass Titanium dioxide in the screen printing paint, add xylene and stir evenly, screen print 2.2m×3.0m flat glass, and then enter the continuous tunnel furnace for baking treatment at 450-520°C; use the film thickness meter to monitor and control the film thickness to 80-95μm . The measured heat transfer coefficient is 5.4w / m.k, which is 10% lower than that of the original flat decorative glass.

Embodiment 3

[0026] Prepare 3.0wt% of kH-590γ-γ-propyltriethoxysilane coupling agent to make a solution; select borosilicate with a heat transfer coefficient K value of 0.065w / m.k, an average diameter of 45μm, and a maximum diameter of 80μm Salt glass hollow glass beads are used as fillers for titanium dioxide; the hollow glass beads are dip-coated with a prepared silane coupling agent solution and dried at 60°C; the original decoration is replaced by 55% of the treated hollow glass beads Add acetone to the titanium dioxide in the screen printing paint for glass, stir evenly, screen print 2.2m×3.0m flat glass, and then enter the continuous tunnel furnace for baking treatment at 500-550°C; use the film thickness meter to monitor and control the film thickness to 90- 130 μm. The measured heat transfer coefficient is 5.3w / m.k, which is 12% lower than that of the original flat decorative glass.

Abstract

The invention relates to a plate glass preparation method capable of enhancing heat-insulating property, which comprises the following steps: carrying out uniform pretreatment on the surface of borosilicate glass hollow glass microspheres with a 0.5-5 wt% silane coupling agent solution; replacing 15-55% of the titanium white component in the paint with the pretreated hollow glass microspheres to prepare a printing paint; adding a small amount of organic solvent, controlling the viscosity and flowability of the printing paint, carrying out plate-making screen printing and overprinting on the plate glass; baking with a continuous tunnel furnace; and preparing a film with the thickness of 40-180 mu m while monitoring and controlling with a film thickness instrument. The invention can enhance the heat-insulating property of decorative sliding door glass.

Description

technical field [0001] The invention relates to the technical field of glass preparation, in particular to a method for preparing flat glass for improving heat insulation performance. Background technique [0002] The improvement of living standards and the deepening of the concept of environmental protection and energy saving have promoted the expansion of architectural decoration aesthetics and energy-saving materials. Flat glass is undoubtedly the best and most economical partition material, but it is cold, colorless, and especially poor in heat and sound insulation. Its performance greatly affects its application, so it is particularly important to improve the heat insulation performance and sound insulation performance of environmentally friendly decorative sliding door glass materials. As a sliding door partition for balconies and rooms, and indoor partitions for office buildings, it can prevent heat energy from entering the room in summer and prevent heat energy from ...
