Description
Technical field
The present invention relates to field of textiles more particularly to a kind of fire-retardant wood fiber non-woven fabric of civil environment-friendlycotton and preparation method thereof.
Background technique
As people gradually can in the material in the fields such as automobile, household to the attention of secure context in many materials
A certain amount of fire retardant is added so that the material has anti-flammability.Currently used fire retardant includes the following categories:
Halogen containing flame-retardant.Halogen containing flame-retardant is all harmful to human body health and environment, is instructed by the European feature of environmental protection
RoHS is forbidden to use.
Expanding halide-free fire-retardant.Their most basic combinations be include ammonium polyphosphate, melamine, pentaerythrite etc. can
To improve carbon source, acid source, the material of expansion also can produce.Expanding halide-free fire-retardant processing difficulties intolerant to migration, are easy to be precipitated
Material surface, the easy moisture absorption, hydrolysis are easy expansion in process and generate bubble, recycle difficult, weatherability difference etc..
Above-mentioned a series of problems all becomes the reason of its application of puzzlement.
Inorganic fire retardants.Inorganic fire retardants will not generate many smog when burning, and releaser is mainly water and carbon dioxide
Etc. the substance that will not cause very major injury to environment, so belonging to environmental type product.But, this based flame retardant fatal defects
It is that flame-retarded efficiency is low, very high additive amount is needed just material can be made fire-retardant, and inorganic fire retardants and organic matter thermoplastic
Property resin compatibility it is very poor, be not easy to disperse in resin, though dispersion, affinity is also bad, thus manufacture material it is past
Toward having the mechanical property that is difficult to accept, or greatly reduce material shock resistance or material it is flexible
Property lose, various reasons result in the limitation of its application, therefore often by the occasion institute of less demanding to material mechanical performance
Using.
Phosphorus fire-retardant agent.In phosphorus fire-retardant agent may red phosphorus flame retardant effect is best, also highest is more for flame retarding efficiency
It is convenient, but its disadvantage shows that color is necessary for red or cooperation black first, this just significantly limits it very
Application in more materials.In addition, although red phosphorus is limited to the various reasons of technique and raw material, in use process by cladding
In or may inevitably cause " fire ", more seriously the processing characteristics of red phosphorus are poor, the phase with resin
Capacitive is also not so good, the material mechanical performance of processing and fabricating is very poor, and the taste of " stench " in production process makes it in addition
It is difficult to be promoted in high-grade material.
It includes halogen and Halogen environment friendly flame retardant that foreign countries, which also develop a variety of, they much also have respective material
Relatively high flame-retarded efficiency, and can produce mechanical property very well, appearance also good fire proofing, but due to valence
The reason of lattice and technology etc., the at present popularization in China are not fine.
The civil fields such as automobile, household are essentially all in process of production to make product play flame retardant effect at present
Addition or powder are impregnated with liquid flame retardant to reach the fire-retardant of product, and when adding powder fire retardant, additive amount is fire-retardant when few
Effect is poor, and when good flame retardation effect, the additive amount of powder alreadys exceed the endurance of product itself, the decline of the physical property of product on the contrary
Can be very serious, to change many original characteristics of product itself.It will lead to when the same liquid flame retardant using impregnation
Fire retardant high temperature resistant is poor, occurs intolerant to the bad problem of washing, sense of touch.
