Description

Technical Field

[0001] This application relates to the technical field of anti-ultraviolet heat-insulating glass, and particularly relates to an anti-ultraviolet heat-insulating glass and a preparation method thereof. Background Art

[0002] Glass is the most common material in our daily life and is closely related to people's production activities. With the development of modern science and technology, glass technology, and the improvement of people's living standards, the functions of architectural glass are no longer limited to meeting the lighting requirements, but also need to have characteristics such as regulating light, heat insulation, bulletproof, anti-theft, fireproof, radiation-proof, anti-electromagnetic wave interference, and artistic decoration.

[0003] In recent years, in order to improve the heat-insulating performance of glass, vacuum glass has been prepared by sealing the peripheries of two flat glasses, evacuating the gap between them into a vacuum, and sealing the exhaust holes. The gap between the two glasses is 0.1 - 0.2 mm. However, this will make the thickness of the heat-insulating glass relatively thick, consuming a lot of manpower and material resources during installation, and often affecting the aesthetic feeling of the overall home decoration after installation; subsequently, porous heat-insulating glass has emerged. Porous heat-insulating glass is prepared by forming a large number of pores in the glass by means of acid immersion or alkali immersion, but this will cause a sharp drop in the compressive strength of the glass.

[0004] In view of this, how to obtain an anti-ultraviolet glass with good heat insulation and relatively good compressive strength has become the focus of the current glass manufacturing industry. Summary of the Invention

[0005] The embodiments of this application provide an anti-ultraviolet heat-insulating glass and a preparation method thereof to solve the technical problems such as poor heat insulation effect and low compressive strength existing in the anti-ultraviolet glass in the prior art.

[0018] The air-curing resin includes: any one of polyurethane with alkoxysilane end groups, polyether with alkoxysilane end groups, polydimethylsiloxane resin or organofunctional silane.

[0019] In a second aspect, an embodiment of the present application provides a method for preparing an ultraviolet-proof and heat-insulating glass, and the preparation method includes:

[0020] Add tris(phthalic acid ethoxysilane) phosphate and aluminum glycinate to ethanol and aqueous solution with a volume ratio of 7:3 respectively, stir, adjust the pH value to alkaline, and add an organic solvent under the condition of below 0 °C and inert gas protection;

[0021] Add glass powder to the above-mentioned mixed solution, stir rapidly for 1-8 h, then place it in a crucible, heat to above 200 °C, cool and wash to obtain the second glass layer;

[0022] Add methyl ketone formamido phenyl ethanol and chloroacetone o-hydroxybenzamidine to dimethyl sulfoxide in a mass ratio of 1:0.55 - 0.65, stir, add rubidium chloride, and cesium carbonate to adjust the pH to neutral, then add the sea bridge cellulose solution, and heat to 90 - 110 °C to obtain the first glass liquid;

[0023] Scrape the bonding liquid onto the surface of the second glass layer, dry and cure it at 60 - 90 °C to form a bonding layer, coat a certain thickness of the first glass liquid on the bonding layer, place it at -5 °C to 0 °C for 1 - 10 h, take it out and dry it at no higher than 90 °C to obtain the anti-ultraviolet heat-insulating glass.

[0031] Further, in an optional embodiment, the mass-volume ratio of methyl ketone formamido phenyl ethanol to dimethyl sulfoxide is (1 - 3) g:(5 - 50) mL.

[0032] Further, in an optional embodiment, the mass ratio of methyl ketone formamido phenyl ethanol to rubidium chloride is (0.1 - 1):(0.0001 - 0.0018).

[0033] An anti-ultraviolet heat-insulating glass and a preparation method thereof provided by an embodiment of the present application further have the following beneficial effects compared with the prior art:

[0034] 1. The anti-ultraviolet heat-insulating glass of the present application adopts multiple layers. Among them, ascidian cellulose is added to the anti-ultraviolet layer. Due to the anti-ultraviolet performance of ascidian cellulose, after hydrolysis with methyl (2-oxobutanoate)phenyl ethanol, o-hydroxyphenyltriazine compounds are formed to act synergistically, enhancing the anti-ultraviolet performance of the heat-insulating glass of the present application. At the same time, ascidian cellulose has infrared absorption performance. Under the synergistic action of absorbing light energy with o-hydroxyphenyltriazine compounds, the heat-insulating performance of the glass is improved.

[0035] 2. In the anti-ultraviolet layer of the present application, through the addition of ascidian cellulose and the growth of controller fibrils in the form of low-temperature freeze-thawing, when exposed to sunlight, the fibrils can transfer the surface heat energy to the heat-insulating layer in the middle layer. And under the protection of the polymer bonding layer, the heat in the second glass layer is easily absorbed but not easily diffused, further improving its heat-insulating performance.

[0036] 3. In the present application, the content of ascidian cellulose added to the anti-ultraviolet layer increases in an increasing manner from the inner surface to the outer surface. The content of ascidian cellulose on the outermost surface of the anti-ultraviolet heat-insulating glass is high. Its fibrils can prevent ultraviolet rays under synergistic conditions and transfer the absorbed heat to the bonding layer and the second glass layer at the same time. While on the side close to the bonding layer, its content is low, preventing the heat absorbed by the second glass layer from being transferred out through a high proportion of fibrils. By controlling the content of ascidian cellulose from the side close to the second glass layer to the outer surface, it can well improve the anti-ultraviolet performance, increase the heat absorption of the glass, and prevent the heat from diffusing out from the inside.

[0037] 4. By adding ascidian cellulose and the bonding layer, fibrils are formed on the outer layer, which can, under synergistic action, improve the compressive performance of the anti-ultraviolet heat-insulating glass, making it not easily damaged after being subjected to pressure.

[0039] Figure 1 It is a schematic structural diagram of an anti-ultraviolet heat-insulating glass provided by an embodiment of the present application;

[0040] Figure 2 It is a flowchart of a preparation method of an anti-ultraviolet heat-insulating glass provided by an embodiment of the present application.

[0041] Through the above drawings, the specific embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter.

Detailed Implementation Modes

[0042] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

In production, raw materials such as PbO, SiO2, TiO2, etc. at the electronic grade are mixed evenly, and then solid-phase reaction is carried out at high temperature to form a glass homogeneous body with a disordered structure. It has stable chemical properties, and its acid resistance has far exceeded that of lead oxide. However, in the chemical composition expression, it is usually converted into oxides according to the usual convention, such as: PbO, SiO2, etc. are used to represent.

The gap between the two pieces of glass is 0.1 - 0.2 mm. However, this will make the thickness of the heat preservation glass relatively thick, consuming manpower and material resources during installation, and often affecting the aesthetic feeling of the overall home decoration after installation; subsequently, porous heat preservation glass has emerged. By adopting the method of acid leaching or alkali leaching to form a large number of pores in the glass to prepare porous heat preservation glass, but this will cause a sharp drop in the compressive strength of the glass.
