Problems solved by technology
[0002] With the improvement of living standards, in order to meet the needs of various colors and decorative aesthetics, the types of building construction materials are increasing day by day, and at the same time, higher requirements are put forward for the fire safety of materials. The fire protection design requirements of various places and buildings, as well as the fire resistance limit of materials, etc., the fire resistance limit of building partitions should be above 2.5H, which shows that existing building materials will still be burned in a high temperature environment for a long time, and the people’s Loss of life and property, and building materials that can withstand fire and high temperature for a long time on the market, or the cost is very high, or can not achieve a good decorative effect

Embodiment Construction
[0035] The present invention will be further described below in conjunction with specific embodiment:
[0036] A kind of preparation method of nanometer fireproof and heat-insulating paint coating, comprises the following steps:
[0037] (1) Prepare component A solution, the specific method is as follows:
[0038] (a), now dissolve the aluminate coupling agent powder in an appropriate amount of methanol, and then add KH560 silane coupling agent to prepare the aluminate silane coupling agent solution;
[0039] (b) Add an appropriate amount of methanol solvent to dilute and stir the crosslinking agent methyltrimethoxysilane and dimethyldimethoxysilane chain extender to prepare the catalyst, disperse and leveling agent for component B the reaction solution;
[0040] (c) Mix the above two solutions (a) and (b) in a closed high-speed stirring container with a constant temperature of 16-20°C. After mixing and stirring at a high speed for 20-30 minutes, observe the solubility of th...
