Abstract

The invention relates to a preparation method of a graphene oxide modified polymer cement waterproofing coating. The polymer cement waterproofing coating is a dual-component aqueous building waterproofing coating prepared by adopting an acrylate polymer emulsion and cement as raw materials and adding other additives; and the polymer cement waterproofing coating has the problems of unsatisfactory mechanical performances, poor impermeability and poor durability, so the promotion and the application of the coatings are severely restricted. The excellent mechanical performances of graphene oxide substantially increase the tensile strength of a film formed by the acrylate polymer emulsion and improve the waterproof property to a certain degree; and additionally, the abundant oxygen-containing function groups of the graphene oxide adjust the growth of a cement hydration product and improve the tensile strength and the toughness of the cement hydration product, so the graphene oxide modified polymer cement waterproofing coating has the advantages of good durability, good impermeability, good physical and mechanical performances, and wide application prospect.

Description

technical field [0001] The invention relates to the technical field of waterproof coatings, in particular to a preparation method of graphene oxide modified polymer cement waterproof coatings. Background technique [0002] Polymer cement waterproof coating is a two-component water-based architectural waterproof coating made of acrylic polymer emulsion and cement as the main raw materials and other admixtures. The products are divided into Type I and Type II. Type I is mainly polymer, which is mainly used for building waterproofing projects in non-long-term flooding environments; Type II is mainly cement, and is mainly used for building waterproofing projects in long-term flooding environments. . This kind of coating not only has the extensibility and water resistance of polymer coating film, but also has the advantages of high strength of water-based gelling material and easy bonding with wet base. However, there are still problems such as unsatisfactory mechanical propert...
