Problems solved by technology

However, during the expansion process of flame-retardant coatings, with the release of a large amount of non-combustible gases, the coating layer is also heated to release a large amount of smoke and toxic gases, including smoke particles, CO, etc., which seriously affect the health and safety of victims and rescuers. Safety of life, hindering evacuation and rescue operations

Abstract

The invention relates to an expanding type smoke-suppression flame retardant for waterborne coating and a preparation method thereof. The smoke-suppression flame retardant is prepared from the following components in parts by weight: 20 to 24 parts of boric acid, 36 to 38 parts of amine polyphosphate, 20 to 24 parts of amidinourea phosphate, 36 to 40 parts of pentaerythritol, 30 to 34 parts of melamine, 1.0 to 1.4 parts of sulfonated carbon, 3.6 to 4.0 parts of zinc borate and 2.0 to 2.4 parts of ammonium octamolybdate. The expanding type smoke-suppression flame retardant provided by the invention is used for preparing waterborne fireproofing flame-retarding coating for surface coating of a wood material; the combustion of the wood material can be greatly delayed in a heating process and fire spreading is inhibited; the waterborne fireproofing flame-retarding coating for the wood material, which is prepared from the expanding type smoke-suppression flame retardant, has the advantages that good smoke-suppression performance is realized; the smoke generation time can be delayed and the release amount of smoke and the generation of toxic gas are reduced; and more safe time and space are provided for escaping and rescuing of people under a fire condition.

Description

technical field [0001] The invention belongs to the technical field of water-based paints, in particular to an intumescent smoke-suppressing flame retardant for water-based paints, and also relates to a preparation method of the intumescent smoke-suppressing flame retardants for water-based paints. Background technique [0002] Wood materials have the advantages of environmental protection, non-toxicity, strong processability and renewable, and are widely used in furniture, construction and interior decoration and other fields. However, untreated wood materials are not fire-resistant, flammable and have fire spread, which will increase the fire risk in the place of use, and there is a serious safety hazard. In order to effectively reduce the occurrence of fires, the country has formulated a series of laws, regulations and safety standards, requiring materials and products used in buildings, indoors or public places to reach the corresponding flame retardant level, which requ...
