Problems solved by technology

[0002] At present, the heat insulation products on the market basically use heat insulation powder to increase the TSR value, such as the common products on the market that use mica sheets to wrap metal oxides. The ability to perform is usually by adding hollow materials, the appearance effect is poor, and it needs to invest a lot of cost
In addition, in order to improve the barrier performance of residual radiant energy, it is necessary to increase the thickness of the paint film, but increasing the thickness of the paint film cannot improve the solar heat reflection efficiency of the paint film, and will significantly increase the cost
Moreover, the heat insulation powder commonly used in the market has a single color and is mainly used to make white water-based paints. For brightly colored paints, the solar heat reflection efficiency cannot be significantly improved; and it has obvious matting effects on oily products, so it cannot be used to make high-gloss, high-fullness paints. oil paint
