Abstract

The invention relates to a flame-retardant spray polyurea elastomer coating and a preparation method thereof. The coating consists of a component A and a component B. The component A comprises the following raw materials in percentage by weight: 40 percent to 60 percent of polyether polyol and 40 percent to 60 percent of polyisocyanates. The component B comprises the following raw materials in percentage by weight: 35 percent to 55 percent of amino terminated polyether, 20 percent to 35 percent of amino terminated chain extender, 20 percent to 40 percent of composite flame retardant and 0.05 percent to 0.1 percent of catalyst. The composite flame retardant comprises the following components in percentage by weight: 29 percent to 58 percent of tetrabromophthlate diol PHT4-DIOL, 6 percent to 12 percent of Tris (2-clorisopropyl) phosphate TCPP, 20 percent to 40 percent of chlorinated paraffin and 10 percent to 25 percent of antimony trioxide. On the basis of keeping good physical properties of materials, the flame retardant property of the coating is further improved. The flame-retardant spray polyurea elastomer coating can be applied to the concrete or steel surfaces of various buildings.

Description

technical field [0001] The invention relates to a building coating, in particular to a polyurea elastomer coating and a preparation method and a construction method thereof. Background technique [0002] Polyurea elastomer coating has good wear resistance, impact resistance, water resistance, corrosion resistance and tensile strength, and is a commonly used spray or scrape coating material with excellent performance. However, because the existing polyurea elastomer coating does not have a flame-retardant function or has a poor flame-retardant effect, it has affected its popularization and use. The flame retardants used in the existing polyurea elastomer coatings with flame retardant function are generally inorganic flame retardants or non-reactive flame retardants. This kind of flame retardant has certain flame retardant properties. Generally, inorganic flame retardants containing elements such as aluminum, boron, zinc, and antimony are used in combination with liquid flame...
