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

Embodiment 1

[0037] Dissolve 2 g of vinyl POSS in 80 g of methanol and stir evenly at room temperature. 0.1 g of benzoyl peroxide was ultrasonically dissolved in 17.9 g of hexafluorobutyl methacrylate at room temperature, then added to the above solution, and stirred under reflux at 80°C for 3 hours to obtain a waterproof coating for construction engineering.

Embodiment 2

[0039] Dissolve 10 g of allyl POSS in 65 g of methanol, and stir evenly at room temperature. 1g of azobisisobutyronitrile was ultrasonically dissolved in 24g of hexafluorobutyl acrylate at room temperature, then added to the above solution, and stirred under reflux at 80°C for 3 hours to obtain a waterproof coating for construction engineering.

Embodiment 3

[0041] Dissolve 4 g of methacryloxypropyl POSS in 65 g of methanol, and stir evenly at room temperature. 1g of azobisisobutyronitrile was ultrasonically dissolved in 30g of dodecafluoroheptyl acrylate at room temperature, then added to the above solution, and stirred under reflux at 80°C for 3 hours to obtain a waterproof coating for construction engineering.

Abstract

The invention belongs to the technical field of macromolecule fine chemical engineering, and discloses a POSS (Posspolyhedral Oligomeric Silsesquioxane) containing construction engineering waterproof coating and a preparation method thereof. The preparation method comprises the following step: polymerizing vinyl-containing POSS and fluorine-containing metacrylic acid ester, thereby obtaining a POSS-containing fluorine-containing metacrylic acid ester polymer, wherein the vinyl-containing POSS is vinyl-containing polyhedron polysilsesquioxane. The polymer disclosed by the invention is good in weather resistance, very good in adhesion property and permeability on building materials such as concrete, good in waterproof effect and applicable to waterproof operation of various types of concrete construction engineering.

Description

technical field [0001] The invention belongs to the technical field of polymer fine chemicals, and in particular relates to a waterproof coating for construction engineering containing POSS and a preparation 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. In addition, du...
