Problems solved by technology

[0004] However, the polyurethane insulation materials on the market basically increase the flame retardant ability of the material by adding flame retardants, such as DMMP and triphosphate. With the addition of these flame retardants, the material will shrink, and the dimensional stability cannot meet the use. demand, and the simple use of flame retardants such as DMMP and triphosphate can only reach the D-level flame retardancy in GB8624-2006, which cannot meet the needs of high flame retardancy

Abstract

The invention discloses a high flame retardance spraying coating and a preparation method thereof. The high flame retardance spraying coating is formed by enabling a component A and a component B to be reacted. The component A comprises, by weight, 100 parts of polyisocyanurate foams, 0.5-3 parts of foam stabilizer, 0.5-2.5 parts of composite catalysts, 10-15 parts of packing and 0.3-6 parts of foaming agents. The component B comprises, by weight, 80-150 parts of methylene diphenyl diisocyanate. The high flame retardance spraying coating prepared by the method has the advantages of being low in viscosity and good in storage stability, production devices are simple, operation in the synthetic process is simple and environmentally friendly, and the reproducibility is good.

Description

technical field [0001] The invention relates to the field of thermal insulation of polymers, and more specifically relates to a high flame-retardant spray paint and a preparation method thereof. Background technique [0002] Polymer compounds are widely used in various fields of production and life. Among them, polyurethane is widely used in construction, decoration and other industries due to its many advantages including fire prevention, low toxicity and high performance. [0003] At present, more than 95% of China's new buildings are still high energy consumption buildings. my country's Ministry of Urban and Rural Housing and Construction has a specific target for building energy conservation. In 2010, new buildings in cities and towns across the country will achieve energy savings of 50%, and by 2020, new buildings in northern and coastal economically developed areas will achieve energy savings of 65%. The polyurethanes disclosed in the prior art are still difficult to...
