Description
Technical field
The present invention relates to field of rubber technology, in particular to a kind of flame retardant rubber and its fire retardant used.
Background technique
Rubber is organic combustible material, harm safety, therefore such as mine rubber conveyer belt and the various rubber products of car and boat,
It is required to flame retardancy and flame retardant property, the rubber of anti-flammability has: neoprene, chlorosulfonated polyethylene, polyvinyl chloride and silicon
Rubber etc..In addition, addition fire retardant be improve rubber flame retardancy method, fire retardant be added to by mechanical mix techniques it is poly-
It closes in object, makes polymer that there is anti-flammability, additive flame retardant mainly has organic fire-retardant and inorganic fire retardants, halogen system at present
Fire retardant (organic chloride and organic bromide) and non-halogen fire retardant.Organic fire-retardant is with bromine system, phosphorus nitrogen system, nitrogen system and red
Phosphorus and compound are some fire retardants of representative, and inorganic fire retardants is mainly antimony oxide, magnesium hydroxide, aluminium hydroxide, silicon
The flame-retardant systems such as system.
Magnesium hydroxide is a kind of novel fire retardant researched and developed in recent years, but in rubbery system, due to magnesium hydroxide
Powder surface contains a large amount of hydroxyl, makes it have stronger polarity and hydrophily, easily formation aggregate, polar fire-retardant in this way
Compatibility and processing fluidity between agent and non-polar polymeric material are deteriorated, therefore how magnesium hydroxide is in rubber bodies in recent years
System obtains dispersing to be research hotspot well, in such as " surface modifier of flame retardant of magnesium hydroxide and application study " article, benefit
Magnesium hydroxide is modified with silane coupling agent and titanate coupling agent, hydrogen-oxygen can be improved well by obtaining silane coupling agent
Change magnesium, disperses it in rubbery system, obtain flame retardant effect well.Chinese patent 201510891183.5 is provided with hard
The polar method of resin acid modified magnesium hydroxide.But modified magnesium hydroxide needs further compatible with high molecular material, rubber at present
Flame retardant property and the mechanical property needs of glue further increase.
Summary of the invention
