Abstract

The invention discloses a fabricated element concrete special-purpose kitchen and bath waterproof agent. The fabricated element concrete special-purpose kitchen and bath waterproof agent comprises, byweight, 10 to 15 parts of modified silicon emulsion, 1 to 2 parts of a zirconium compound, 3 to 6 parts of a organic silicone surfactant, 10 to 15 parts of water-soluble polyurethane resin emulsion,0.1 to 0.4 part of an air entraining agent, 2 to 5 parts of a water reducer, and 1 to 4 parts of a thickening time control agent. According to a preparation method of the fabricated element concrete special-purpose kitchen and bath waterproof agent, organic compounds including the organic silicone surfactant and the water-soluble polyurethane resin emulsion are adopted, and are combined with the air entraining agent, the zirconium compound, the water reducer, and the thickening time control agent to prepare the composite waterproof agent. Compared with convention waterproof agent, the advantages of the composite waterproof agent are that: construction is simple; the composite waterproof agent is safe, and is friendly to the environment, possesses extremely excellent water resistance, is capable of reducing concrete water glue ratio, improving concrete workability and compactness, reducing concrete shrinkage rate further, filling concrete internal pores, and achieving impervious grade increasing, pressure resistance, and high strength.

Description

technical field [0001] The invention relates to the technical field of waterproofing agent preparation, in particular to a special kitchen and bathroom waterproofing agent for prefabricated component concrete. Background technique [0002] Concrete, referred to as "concrete" for short: refers to the collective name of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; and water, which may contain admixtures and admixtures, mixed in a certain proportion, and stirred. Concrete, which is widely used in civil engineering, is one of the most important contemporary civil engineering materials. It is composed of cementitious materials, granular aggregates, also known as aggregates, water, and admixtures and admixtures added when necessary, prepared in a certain proportion, u...
