Abstract

The invention discloses an environment-protection transparent intumescent-type aqueous flame-retardant paint, and a preparation method and applications thereof, and belongs to the field of paint. Thepreparation method is used for solving problems in the prior art, that in using process of conventional flame retardant paint, halogen containing toxic organic volatile matters are released, flame retardant effect is poor because of the high dehydration catalyst temperature, and nontransparent paint using range is limited. The environment-protection transparent intumescent-type aqueous flame-retardant paint is composed of a component A, a component B, and a paint auxiliary agent. The preparation method comprises following steps: the component A is prepared; the component B is prepared from melamine formaldehyde resin and / or melamine modified urea-formaldehyde resin; the component A and the component B are mixed, the paint auxiliary agent is added, and an obtained mixture is stirred to be uniform so as to obtain the environment-protection transparent intumescent-type aqueous flame-retardant paint. The environment-protection transparent intumescent-type aqueous flame-retardant paint usedfor flame retardant protection of indoor timber structure materials, wood plastic composite materials, steel structure materials, or concrete structures.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to the technical field of an environmentally friendly flame-retardant coating and its preparation method and application. Background technique [0002] With the improvement of people's living standards and the rapid development of the construction industry, wood and a large number of flammable materials are used in building materials, interior decoration and even wooden house construction, which poses a huge fire safety hazard. The preparation of high-efficiency new non-combustible, flame-retardant, low-toxic and environmentally friendly decorative materials is one of the trends in material development in the future. The flame-retardant coating coated on the surface of the base material can effectively prevent the occurrence and spread of fire, and can significantly reduce the loss caused by fire. It has the advantages of low cost, complex variable use and wide application. [0...
