Abstract

The present invention belongs to the technical field of modification of flame-retardant ethylene-vinyl acetate copolymers, and discloses a flame-retardant composite material containing a mesoporous titanium dioxide-hydrotalcite hybrid material, and a preparation method thereof, wherein the flame-retardant composite material comprises, by mass, 95.00-99.00% of an ethylene-vinyl acetate copolymer and 1.00-5.00% of a mesoporous titanium dioxide-hydrotalcite hybrid material, and the mesoporous titanium dioxide-hydrotalcite hybrid material is one or two selected from a mesoporous titanium dioxide-magnesium iron hydrotalcite hybrid material or mesoporous titanium dioxide-magnesium aluminium iron hydrotalcite hybrid material. According to the present invention, the flame-retardant composite material has advantages of significantly reduced heat release rate, significantly reduced total heat release, significantly reduced smoke generation rate, significantly reduced total smoke generation amount and significantly reduced smoke factor, and has the substantially increased remaining carbon residue mass.

Description

technical field [0001] The invention relates to the technical field of flame-retardant ethylene-vinyl acetate copolymer modification, in particular to a flame-retardant composite material containing mesoporous titanium dioxide-hydrotalcite hybrid material and a preparation method thereof. Background technique [0002] Ethylene-vinyl acetate copolymer (EVA) is one of the most important ethylene copolymers. Compared with polyethylene (PE), the EVA matrix resin reduces high crystallinity and improves flexibility, impact resistance, and environmental stress cracking resistance (ESCR) due to the introduction of vinyl acetate monomer (VA) into the molecular chain. And good optical properties, low temperature resistance and non-toxic characteristics. EVA resin has excellent performance and is widely used. It can be used in the production of hot melt adhesives, injection products, films, foams, pipes, wires / cables, plates, etc., and can also be used in the production of chemical b...
