Abstract

The invention relates to nanometer fluorocarbon exterior wall heat insulation paint, which is prepared from ingredients according to the following weight proportion: the ratio of acrylics to fluorocarbon resin to nanometer SiO2 to titanium pigment to silicon acrylate latex to calcium carbonate to foam suppressor is 100-220 to 100-200 to 20-50 to 10-18 to 80-150 to 20-50 to 10-20. The invention makes the structure and the chemical composition part of transparent paint regulated to the most scientific and most reasonable state, and adds a few nanometer grade materials, so that the exterior wall paint is non-toxic and odorless, and accords with the requirement of environmental protection; a paint film resists water, has quite strong performances of acid and alkali resistance and mildew resistance; and the paint film can cover fine cracks. The nanometer fluorocarbon exterior wall heat insulation paint has the advantages of strong adhesive force, good heat insulation performance and low cost.

Description

technical field [0001] The invention relates to an exterior wall coating, in particular to a nano-fluorocarbon exterior wall thermal insulation coating widely used in cement wall surfaces, concrete, plastering surfaces, stonewashed stones and wooden structure bases. Background technique [0002] Nano is the smallest unit of length measurement. The length of 1 nanometer is one millionth of a millimeter. Nanotechnology is within the length range of 1nm-100nm, directly using atoms, atomic groups, molecules, and molecules that make up various elements and substances. Group assembly of materials with specific functions or high-tech technologies with special performance products. Successful nanotechnology can be applied in various fields such as electronics, chemical industry, and military affairs, and all countries in the world are researching and developing it. The application of nanotechnology (nanometer raw materials) in coatings mainly uses the mechanism of lotus leaves and ...
