Problems solved by technology

[0004] At present, many fire safety accidents in our country are mainly caused by cross-site operations, which make the open flames come into contact with the organic insulation materials that have not been protected by the covering and the insulation system does not have a reasonable fire protection belt. At present, there is no A material that can effectively solve the problems of easy fire in the construction process of organic thermal insulation materials and the reduction of thermal insulation effect caused by leakage after construction

Abstract

The invention discloses a flame-retardant waterproof material which can be used in an exterior wall outer insulation system. The material comprises two components which are respectively a liquid material and a powder material. The liquid material comprises the components of: silicone acrylic emulsion, a preservative, a dispersing agent, a defoaming agent, a wetting agent, and water. The powder material comprises the components of: common Portland cement, high-aluminum cement, quartz sand, cellulose ether, a water-reducing agent, and a flame retardant. The material is used in an exterior wall outer insulation system, and solves problems of high flammability and fire-prone property of an organic insulation plate of a current exterior wall outer insulation system during construction and after application. Also, the product has good flexibility and water resistance, such that a problem of reduced insulation effect after the exterior wall cracks and water is let in is solved.

Description

technical field [0001] The invention relates to a building material, in particular to a flame-retardant and waterproof material that can be used in an external wall thermal insulation system with an organic thermal insulation material as the main body. Background technique [0002] At present, fire accidents caused by flammable external wall thermal insulation materials abound, resulting in heavy casualties and property losses. Therefore, relevant state departments, such as the Ministry of Public Security and the Ministry of Housing and Urban-Rural Development, have issued many documents to improve the external wall thermal insulation system of buildings. It is clearly stipulated that the building exterior wall insulation materials must meet the requirements of Class A flame retardant and fire protection. At present, it is difficult for traditional organic insulation materials such as polystyrene boards on the market to meet such requirements, so their use is widely restricted...
