Problems solved by technology

The disadvantage of fluoropolymer is that its adhesion is poor. Due to the extremely low surface energy of fluoropolymer, its interaction with the polar concrete surface is weak, so it is easier to fall off and cause waterproof effect lost

Abstract

The invention belongs to the technical field of polymer fine chemicals, and discloses a POSS and silicone oil modified fluorinated acrylate building waterproof paint and a preparation method thereof. The preparation method comprises adopting POSS, silicone oil and fluorinated methacrylate to perform the copolymerization to obtain POSS-containing silicone oil modified fluorinated methacrylate polymer, wherein the selected alkenyl-containing POSS is polyhedral polysilsesquioxane containing alkenyl. The polymer disclosed by the invention has good weather resistance, has good adhesive force and permeation to concrete and other building materials, has a good waterproof effect, and is suitable for the waterproof work of various concrete constructions.

Description

technical field [0001] The invention belongs to the technical field of polymer fine chemicals, and in particular relates to a POSS and silicone oil-modified fluorine-containing acrylate architectural waterproof coating and a method thereof. Background technique [0002] A large number of modern buildings with reinforced concrete structures, no matter from the building materials themselves, or the inner and outer walls of the building, the application research of its waterproof and impermeability performance has increasingly attracted the attention of scientific researchers and construction personnel. Due to the Ca in concrete, ceramics, masonry and other materials 2+ , Mg 2+ 、Al 3+ Such soluble salts are prone to water-soluble migration, which will cause the surface of the building to weather and form salt frost, which affects the visual appearance of the building, and will cause cracks on the wall surface, resulting in damage to the texture and durability of the building....
