Abstract

The invention discloses a preparation method of a low-cost coated flame-retardant smoke suppressant. The method comprises the following steps: ultrasonically dispersing and dissolving soluble tin salt, soluble metal salt and a surfactant in deionized water containing nano calcium carbonate dispersion liquid by adopting a sedimentation method, then adding a precipitator, carrying out coating reaction at 50-80 DEG C, taking out precipitates, washing with deionized water, and drying a washed product to obtain the coated flame-retardant smoke suppressant. The method has the advantages of short flow, high efficiency, convenient control of reaction conditions, and good industrial development prospect.

Description

technical field [0001] The invention relates to flame retardant material preparation technology, flame retardant and smoke suppression technology, in particular to a preparation method of a low-cost coated flame retardant and smoke suppressant. Background technique [0002] Soft PVC is widely used in construction, interior decoration, cables and other living places. With the development of society and the prosperity of economy, people have higher and higher requirements for fire safety; 80% of the deaths in fires are caused by the incomplete combustion of polymer materials in fires resulting in a large amount of toxic gases and shading smoke caused by suffocation. [0003] At present, the flame retardants in the domestic market include antimony-based, phosphorus-based, halogen-based, silicon-based, etc., but antimony-based flame retardants have poor smoke suppression performance, high smoke production, and antimony oxide is also toxic; phosphorus-based flame retardants The...
