Problems solved by technology

Although the crystal form of zinc hydroxystannate prepared by this method is complete, but the crystal particle size is relatively large, the storage and consumption amount as a flame retardant and smoke suppressant is large, the cost performance of flame retardant is low, and the mechanical properties of composite materials are seriously damaged.
[0005] 2-Amino-1,3,5-triazine-4,6-dithiol, its Chinese alias: 6-A-1,3,5-tripyridine-2,4-dibutyl ester, its English name is 2 -amino-1,3,5-triazine-4,6-dithiol, CAS No. 2770-75-4, melting point 360°C, has good thermal stability and good carbon-forming ability, but its single use is harmful to compound The flame retardancy of the material does not contribute

Abstract

The invention provides a zinc hydroxystannate-palygorskite-mercaptan composite flame retardant with good flame retardant property. The zinc hydroxystannate-palygorskite-mercaptan composite flame retardant is prepared by compounding a zinc hydroxystannate-palygorskite clay compound and 2-amino-1,3,5-triazine-4,6-dimercaptan according to a mass ratio of 100: 1. Experiments show that 2-amino-1,3,5-triazine-4,6-dimercaptan and the zinc hydroxystannate-palygorskite clay compound have good synergistic effects; a flame retardant material prepared by using 2-amino-1,3,5-triazine-4,6-dimercaptan and the zinc hydroxystannate-palygorskite clay compound as additives is good in carbonization effect, and can be widely applied to modification of plastics and various rubber.

Description

technical field [0001] The invention relates to a composite flame retardant, in particular to a zinc hydroxystannate-palygorskite-mercaptan composite flame retardant; the invention also relates to the preparation and application of the composite flame retardant. Background technique [0002] Polymer materials, especially plastic and rubber products, are widely used in building materials, home appliances, transportation, textiles, communications and other industries, but most of the polymer materials are flammable, causing serious damage to their application industries and people's lives and property. Therefore, the preparation of high-performance flame-retardant materials has become an urgent problem to be solved by the society. [0003] At present, there are two main types of flame retardant materials: additive type and intrinsic flame retardant. Due to the simple preparation process, wide source of raw materials and low price of additive flame retardant materials, they ar...
