Abstract

The invention discloses a preparation method of a waterproof heat-insulating glass coating, and belongs to the technical field of coating preparation. According to the preparation method provided by the invention, a modified self-made polyurethane emulsion is used as a matrix, a self-made nano antimony tin oxide dispersion liquid and modified mixed powder are used as modifying reinforcing agents,and a coupling agent, a defoaming agent and a thickening agent are supplemented to prepare the water-proof heat-insulating glass coating. Firstly, a silane coupling agent KH-550 is used to modify polyurethane resin, so that the water absorption of the glass coating is gradually reduced; and then an effect of reducing light transmission and heat transfer is achieved through the nano antimony tin oxide under the action of deionized water, dispersion substances and absolute ethyl alcohol. According to the preparation method, mixed powder formed by mixing and grinding hollow glass beads, calcium carbonate and silica fume is sequentially added, wherein the hollow glass beads have a hollow structure and have excellent heat-insulating performance, and in addition, the calcium carbonate and the submicron-grade silica fume fine particles have excellent penetrability, so that the adhesive strength and the water resistance can be enhanced, and the preparation method has a wide application prospect.

Description

technical field [0001] The invention discloses a preparation method of a waterproof and heat-insulating glass paint, which belongs to the technical field of paint preparation. Background technique [0002] Glass coating is a kind of coating. The glass surface is usually very smooth. Ordinary coatings are difficult to adhere to the glass surface. Good glass coatings form a stable and hard paint film on the glass surface, which will show high transparency and high gloss in appearance. specialty. In construction, the viscosity is usually low, and at the same time, it will not cause sagging. It can be stably adhered to the surface of glassware, and it can beautify and decorate glassware through different colors. Because glass does not have a good performance of insulating heat radiation, the problem of high energy consumption caused by its application in buildings or structures or other fields has attracted a lot of attention. In particular, thousands or even tens of thousand...
