Problems solved by technology

[0002] At present, with the continuous development of technology and the changing of people's aesthetic concept, glass materials are more and more widely used in daily life. It is widely used in the construction industry, especially for partitioning rooms and housing curtain walls. However, the currently used glass often bursts when it encounters an open flame, not only cannot play the role of fire prevention, It will also cause harm to personnel, and due to the good thermal conductivity of the glass, the user may be scalded by the hot glass when escaping;

Embodiment 1

[0041] This embodiment is a high temperature resistant resin, and the high temperature resistant resin is prepared by the following steps:

[0042] S1: Add 3,5-difluoroaniline into a three-neck flask equipped with a constant pressure dropping funnel and a stirrer, add glacial acetic acid, and stir until 3 at a temperature of 30°C and a stirring rate of 100r / min. 5-Difluoroaniline is completely dissolved, then add deionized water and continue to stir for 10 minutes, then add concentrated sulfuric acid drop by drop, control the dropping rate at 1 drop / s, keep the temperature of the reaction system not higher than 45°C during the dropping process, add dropwise After the completion, continue to stir the reaction for 10 minutes, then cool the reaction system to 0°C, add the sodium nitrite solution dropwise while stirring at a stirring rate of 500r / min, control the dropping rate at 0.8mL / min, continue to Stir the reaction for 30 minutes, add diethyl ether and continue stirring for 3...

Embodiment 2

[0050] This embodiment is a high temperature resistant resin, and the high temperature resistant resin is prepared by the following steps:

[0051] S1: Add 3,5-difluoroaniline into a three-necked flask equipped with a constant pressure dropping funnel and a stirrer, add glacial acetic acid, and stir until 3 at a temperature of 35°C and a stirring rate of 200r / min. 5-Difluoroaniline is completely dissolved, then add deionized water and continue to stir for 20 minutes, then add concentrated sulfuric acid drop by drop, control the dropping rate at 1 drop / s, keep the temperature of the reaction system not higher than 45°C during the dropping process, add dropwise After the completion, continue to stir the reaction for 20 minutes, then cool the reaction system to 0°C, add the sodium nitrite solution dropwise while stirring at a stirring rate of 800r / min, control the dropping rate at 1mL / min, and continue stirring after the dropping is completed After reacting for 50 minutes, diethy...

Embodiment 3

[0059] This embodiment is a production process of high heat-resistant explosion-proof glass. The high-temperature-resistant resin from Example 1 is melted, and the melted high-temperature-resistant resin is cast on the upper and lower surfaces of the tempered glass to form a thin film, forming A heat-resistant explosion-proof film is used to obtain the high heat-resistant explosion-proof glass.

Abstract

The invention discloses a high heat-resistant explosion-proof glass and its production process, which relates to the field of glass materials. By melting the high-temperature-resistant resin, the melted high-temperature-resistant resin is cast on both the upper and lower surfaces of the tempered glass to form a layer. film to form a heat-resistant explosion-proof film to obtain the high heat-resistant explosion-proof glass; the heat-resistant explosion-proof film has fireproof performance, and can effectively block heat transfer after being compounded on the surface of the tempered glass, thus endowing the tempered glass with good heat resistance. , the existence of the heat-resistant explosion-proof film improves the mechanical properties of tempered glass, making it difficult to break. At the same time, the broken pieces are adhered by two layers of heat-resistant explosion-proof film, which can greatly reduce the damage to personnel and valuables in the event of violent impact, and is safe. high sex.

Description

technical field [0001] The invention relates to the field of glass materials, in particular to a high heat-resistant explosion-proof glass and a production process thereof. Background technique [0002] At present, with the continuous development of technology and the changing of people's aesthetic concept, glass materials are more and more widely used in daily life. It is widely used in the construction industry, especially for partitioning rooms and housing curtain walls. However, the currently used glass often bursts when it encounters an open flame, not only cannot play the role of fire prevention, It will also cause harm to personnel, and due to the good thermal conductivity of the glass, the user may be scalded by the hot glass when escaping; [0003] Therefore, how to improve the existing glass materials that are easy to burst and difficult to resist fire and heat is a problem to be solved by the present invention. Contents of the invention [0004] In order to ov...
