Abstract

The invention discloses fluoro-siloxane resin, a preparation method thereof and application thereof as an artificial stone antifouling agent. The fluoro-siloxane resin, the preparation method and the application have the benefits that vinyl silicone, 2-(perfluorinated butyl) ethyl methyl acrylic ester and the like are adopted to prepare a series of fluoro-siloxane resin; the synthesis method is scientific and reasonable, so that a universal method for synthesizing a series of fluoro-siloxane resin is provided, and the preparation method is easy to get raw materials, wide in application range, high in yield and simple and feasible in industrial production operation.

Description

technical field [0001] The invention relates to the technical field of building material production, in particular to a fluorosilicone resin, a preparation method and an application thereof. Background technique [0002] The development of stone protective agents in foreign countries has a history of more than 30 years. Some countries such as Japan, Europe and the United States are in the leading position in the research of stone protective agents, and have gradually transitioned from solvent-based products to water-based products. research is relatively late. At present, the country has just established relevant industry standards, and most of the protective agents used are imported from Japan, Europe, America and other countries. In some European and American countries, since the beginning of this century, research on professional stone maintenance has been started to maintain the original brilliance of the stone and prolong its service life. At present, countries with m...
