Description
Technical field
The present invention relates to sponge material field, specially a kind of halogen-free flameproof sponge and preparation method thereof.
Background technique
Flexible polyurethane foam is a kind of novel high polymer material, it is with toluene di-isocyanate(TDI) (abbreviation TDI)
It is synthesized with polyether polyol polycondensation reaction, full name is polyamine group methyl esters, is commonly called as sponge.Since its density is small, elasticity is good, sound insulation
It is shockproof, safety and comfort are taken, molding construction convenience, cheap feature have enough intensity, oil resistivity and cementability, be
Excellent heat-barrier material, therefore, be widely used in medical wrapping product, industrial environment laboratory, building ventilation, air-conditioning duct and
Food service industry freezing, freezer () are used as heat preserving and insulating material, and the polyurethane foam plastics of rockiness can be also used for building
Object insulation system；Especially very universal in the industries use such as furniture, bed accessory, transport, refrigeration, building, insulation, having become can not
One of material lacked.
Polyurethane is a kind of flammable polymer, especially soft polyurethane foam, has porous structure, is very easy to combustion
It burns, poisonous smog can be generated after burning, easily causes the death by suffocation of people.Cause or propagating flame be because polyurethane by
It can be decomposed after heat, generate unstable combustible products such as hydrogen cyanide etc..Since soft polyurethane foam is largely used to furniture, auto industry
And in building, therefore a possibility that fire and fire occur is substantially increased, there are many case of this respect.In addition, by
Has the characteristics that cavernous structure in soft polyurethane foam, being easy to happen aphlogistic smouldering and soft polyurethane foam can not neglect
Depending on harm.In order to avoid the generation of fire, reduce fire can the loss of energy, the research and development of the soft bubble of flame retardant polyurethane increasingly by
Pay attention to both at home and abroad.
It is a large amount of it is demonstrated experimentally that most fire retardants can all cause foam to collapse bubble, contraction or cracking in foaming process,
Fire retardants only few in number can be used, and flame retardant effect is not significant when these fire retardants individually add, and is made
Foam physical mechanical property it is poor.Simultaneously as using more brominated flame-retardant, foamed plastics combustion product gases toxicity also compared with
Greatly.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of halogen-free flameproof sponge and preparation method thereof, is hindered using Halogen
Agent is fired, by formula technique research and the innovation of production technology, product has low VOC, environmental protection, health, nontoxic, not carcinogenic
Etc. characteristics and superior physical property.

Component A is made after being mixed in injection nitrogen；
(2) water, catalyst, toluene di-isocyanate(TDI) and component A are quickly poured into mold after mixing, are foamed into
After type to obtain the final product.
Preferably, preparation process carries out under 22 DEG C of constant temperature, 60% damp condition.
The present invention uses halogen-free flame retardants, and determines optimization formula ratio using formula design by selection, reduces inflammable
The dosage of ingredient polyether polyol improves the fire protecting performance of polyurethane soft foamed plastics from formula technique.
The present invention replaces air foam process using nitrogen gas foaming technique, and foamed plastics oxygen content is effectively reduced, effectively keeps away
Exempt from because of the case where savings of heat leads to foamed plastics spontaneous combustion generation, and since foamed plastics itself oxygen content is few, and it is similar
Product is compared, and flame retardant property significantly improves, and reaches the fire-protection standards such as the U.S., Britain.
Flame-retardant sponge density (d) prepared by the present invention is 28kg/m3, 25% compressive hardness is ILD.
The beneficial effects of the present invention are:
(1) common foamed plastics is foamed using air, and a large amount of oxygen, power-assisted combustion are contained in foamed plastics obtained
It burns, fire protecting performance is bad.The present invention passes through independent research, replaces air foam process using nitrogen gas foaming technique, reaches reduction
Foamed plastics oxygen content effectively improves the purpose of fire protecting performance.
(2) present invention ensures the physical indexs such as tensile strength, the degree of collapsing of product while guaranteeing product fire protecting performance
Reach peak demand, makes product that there is high resiliency, be unlikely to deform.
