[0018] Example

[0019] The present invention provides a technical solution: a method for preparing an environmentally friendly cloth heat-insulating and fire-proof material.

[0020] Prepare according to the following steps:

[0021] S1. Weigh magnesium hydroxide, magnesium oxide, aluminum hydroxide, ammonium bicarbonate, silicon dioxide and sodium oxide according to a certain proportion and add them to an appropriate amount of solvent.

[0022] S2. Stir thoroughly in a stirring device to disperse it evenly in the solvent to form a stable solution.

[0023] S3. Add appropriate amount of environmentally friendly additives to the solution as needed and continue stirring until it is completely dissolved.

[0024] S4. Filter the prepared solution to remove impurities and undissolved particles to ensure the purity and effectiveness of the solution.

[0025] S5. Conduct performance tests on the prepared environmentally friendly fabric thermal insulation and fireproof material solution, including indicators such as solution viscosity, stability, flame retardant effect, and thermal insulation performance, to ensure that the various properties of the solution meet the predetermined requirements. Based on the test results, make necessary adjustments and optimizations to its formula and preparation process.

[0026] S6, packaging, waiting for shipment;

[0027] In this embodiment, specifically: the magnesium hydroxide and aluminum hydroxide in S1 achieve the flame retardant effect by absorbing heat and forming an isolation layer;

[0028] In this embodiment, specifically: the silicon dioxide in S1 has the characteristics of high fire resistance, high temperature resistance, small thermal expansion coefficient, high insulation, and corrosion resistance;

[0029] In this embodiment, specifically: the solvent in S1 is water or a low-volatile organic solvent;

[0030] In this embodiment, specifically: the environmentally friendly additive in S3 can improve the stability and coating performance of the solution.

[0031] Working principle or structural principle: First, when the environmentally friendly cloth insulation and fireproof material is heated, when magnesium hydroxide is heated to 350℃, it will lose water to generate magnesium oxide. Magnesium oxide has highly fire-resistant and insulating properties. These oxides will cover the surface of the material to form a dense protective film, isolating the transfer of oxygen and heat, and preventing further combustion. In addition, ammonium bicarbonate is unstable when heated and easily decomposes to produce ammonia, carbon dioxide and water. The generated ammonia and carbon dioxide gases will form a protective layer around the flame, isolating the contact between oxygen and the combustion products, and can dilute the concentration of combustible gases and oxygen, preventing the combustion from continuing. It has good heat insulation and oxygen isolation effects, further inhibiting the spread of combustion. At the same time, the gas generated during the decomposition process will also take away part of the heat, which has a certain cooling effect on the flame and the combustion products. Secondly, the water vapor generated by the decomposition can dilute the concentration of combustible gases and oxygen, reduce the occurrence of combustion reactions, and delay the combustion process, thereby reducing the surface temperature of the material and playing a cooling role.

[0032] It can be seen from this that the present invention provides a method for preparing an environmentally friendly cloth heat-insulating and fire-proof material solution. By carefully selecting environmentally friendly raw materials and a scientific preparation process, the prepared solution can not only effectively improve the heat-insulating and fire-proof properties of the cloth, but also meet environmental protection requirements.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
