Problems solved by technology

The existing cement-based waterproof coating has poor bonding strength with the base layer, is easy to crack, and has a large difference from the service life of waterproofing. The content of cement sand and rubber powder are the keys to crack-resistant cement-based waterproof coatings.

Abstract

The invention discloses a graphene-modified cement-based waterproof coating. The graphene-modified cement-based waterproof coating comprises, by weight, 52 to 60 parts of Portland cement, 38 to 48 parts of quartz sand, 1.5 to 3 parts of lignocellulose, 3 to 8 parts of a water-repellent agent, 2 to 4 parts of redispersible rubber powder, 4 to 8 parts of graphene nano-sheets, 0.1 to 0.5 parts of a water-reducing agent and 0.1 to 0.3 parts of a filler. Compared with the existing crack resistant cement-based waterproof coatings, the graphene-modified cement-based waterproof coating has higher performances.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a graphene-modified cement-based waterproof coating. Background technique [0002] In some low-strength bases, the traditional method is to pour cement concrete inside and outside the surface and underground or masonry, and then after the cement concrete is cured, level it with cement mortar, and then apply waterproof coating, and then Then make a protective layer on the waterproof coating, but the traditional cement-based waterproof coating has low bonding strength, and it is easy to crack and detach between the base layer of the concrete and the waterproof layer, and it is easy to fall off and touch hard objects (such as: Red bricks, gray knives, steel heads, etc.), are also prone to cracking and falling off, seriously affecting the service life and waterproof effect. The surface of the original waterproof layer is smooth, especially when doing waterproo...
