Description

technical field [0001] The invention relates to a fluorine-silicon nanometer waterproof and heat-insulating composite material and a preparation method thereof. Background technique [0002] With the development of the construction industry, the development and application of various waterproof coatings have developed rapidly, which puts forward higher requirements for the quality and performance of architectural waterproof coatings, which can ensure that buildings do not leak or are painted waterproof after leakage. Insulation paint can seal the leakage site. The common problem is that the coating exposed to the outermost layer of the building, under the use of acid rain, the outermost layer is damaged, and then the built-in waterproof layer is damaged, which reduces the protection ability of the coating to the building body; in addition, the existing Waterproof and heat-insulating coatings have great harm to human body and environment. Contents of the invention [0003...
