Polyvinyl alcohol waterproof coating

Abstract

The invention discloses a polyvinyl alcohol waterproof coating, which is mainly prepared by stirring the following raw materials in part by weight: 100 parts of polyvinyl alcohol, 20 parts of carboxymethylcellulose, 25 parts of sodium potassium silicate, 30 parts of pentyl acetate, 15 parts of triethanolamine, 10 parts of carboxymethylcellulose, 40 parts of magnesium silicate, 85 parts of water, 6 parts of binder, 6 parts of film-forming aid, 6 parts of dispersing agent and 5 parts of defoamer. The polyvinyl alcohol waterproof coating has high workability, cost performance and water repellency, and aquatic organisms are prevented from being precipitated or grown on a hull.

Description

technical field [0001] The invention relates to a polyvinyl alcohol waterproof coating. technical background [0002] At present, the outside of the hull needs to be coated with waterproof paint to ensure that the hull will not be oxidized and corroded, but after the hull is coated with waterproof paint, other coatings are used to prevent aquatic organisms from settling and growing on the hull. However, applying multiple different paints in this way is time-consuming and expensive. Contents of the invention [0003] The object of the present invention is to provide an antifouling polyvinyl alcohol waterproof coating in order to overcome the deficiencies of the prior art. [0004] In order to solve the above problems, the technical solution of the present invention is: a kind of polyvinyl alcohol waterproof coating is made by stirring according to the weight ratio of the following raw materials: 100 parts of polyvinyl alcohol, 20 parts of carboxymethyl cellulose, 25 parts ...
