Description

A kind of low VOC halogen-free flameproof wear-resisting floor wearing floor leather and its preparation process
Technical field
The present invention relates to flame-retarding new material technical field, more particularly, to a kind of low VOC halogen-free flameproof wear-resisting floor wearing floor leather and Its preparation process.
Background technique
In the vehicles and closed public place, fire is an important hidden danger for jeopardizing people's security of the lives and property. Plastic material be very easy to burning, but in the plastic addition fire retardant may be implemented it is fire-retardant.For many years, by flame-retarded technology Limitation, the fire retardant flameproof effect of the halogens such as brominated (Br), chlorine (Cl) is good, is widely used in the ornament materials such as flooring laminate In, such as China's flooring laminate material applied currently on the market is mainly polyvinyl chloride (PVC) material, potentially hazardous or ratio It is biggish.
" brominated, chlorine fire retardant can be released hydrogen bromide, hydrogen chloride by thermal decomposition, be captured in polymer combustion production object immediately Free radical and prevent flame propagation, reach fire-retardant." on the one hand, halogen flame retardant material can generate largely in combustion Smog toxicity increases the escape risk and escape time of personnel.Hydrogen chloride has strong impulse to eye and respiratory mucosa simultaneously Effect, hydrogen bromide can then cause skin, mucous membrane stimulation or burn.If not can be carried out effective after halogen flame retardant materials'use Classify and be mixed into house refuse and carry out burning disposal, will also become one of the source of PM 2.5 and groundwater environment pollution.
In addition to halogen flame, liquid phosphoric acid esters fire retardant is also widely used in automobile-used leather material, due to its sudden strain of a muscle Point is low, as the plasticizer of PVC, it has also become one of in-vehicle air pollution, peculiar smell and main source of VOC.
With people environmental consciousness and comfort require be continuously improved, vehicles lightweight, fire safety with it is low The contradiction of VOC, low smell and recoverable become increasingly conspicuous, for the Green Development for pushing material used for vehicle, GB/T 27630-2011 " Air Quality Evaluation guide in passenger car ", the Ministry of Industry and Information Technology issue No. 38 bulletin-" vapour in 2015 Vehicle harmful substance and recoverable rate management requirement ", the internal securitys such as GB/T 30512-2014 " requirement of automobile banned substance " Environmental regulation is put into effect in succession.The environmental protection flame retardant technology upgrading of automotive material is extremely urgent.
Non-PVC flooring removes from office material, polyurethane elastomer, rubber, polyolefin material, thermoplastic elastomer (TPE) SEBS, TPO, TPU Pavement study increased popularity.To meet rail traffic, automobile, public arena high fire-retardance and environmental requirement, the prior art Inorganic fire retardants can generally be added to improve flame retardant property, but inorganic fire retardants flame retarding efficiency is low, additive amount is big, on the one hand right The physical mechanical property deterioration of high molecular material has an impact, and on the other hand also makes product surface density big, difficulty meets rail traffic Light-weighted requirement.
For example, application publication number CN103113681A, the Chinese patent of data of publication of application 2013.05.22 discloses one kind Flame-retardant rubber floor for ship, formula mainly consist of the following compositions: master composes rubber EPDM, blend compounds, rubber Combustion inhibitor special, rubber specific complex fire retardant, reinforcing agent modified Nano silicon chloride, fire-proof smoke suppressor, nano flame retardant antismoke agent, Plasticizer, no blooming promotor, activating agent, lubricant, reinforcing agent, silane coupling agent, comprehensive anti-aging agent, filler, dispersing agent, Homogenizing agent, tackifier, antioxidant, electrostatic agent, the steady agent of light, vulcanizing agent, sulphur, promotor and color inhibition promotor etc..This is fire-retardant Rubber floor covering compounds rubber combustion inhibitor special by substrate of ethylene propylene diene rubber, but uses bromide fire retardant.
Patent " ethylene copolymer composition CN95106103.8 used in manufacture pavement " is with magnesium hydroxide and hydrogen-oxygen Change the inorganic fillers flame-proof ethylene copolymers such as aluminium inorganic fire retardants compounding kaolin, calcium carbonate, precipitated carbonate, although oxygen index (OI) Greater than 30, but product density is higher, wears no resistance lower than 300mm3, scratch-resistant be higher than 150g, be not able to satisfy motor-car EN649 rule Fixed T class requirement.
Patent " a kind of SEBS thermoplastic elastomer floor and its manufacturing method CN200710074527.9 " mineral filler 200-400 parts, unit area abrasion loss≤0.032g/cm2, and it is not fire-retardant.
Patent " non-PVC flooring made of thermoplastic elastomer (TPE) and its manufacturing method CN200580001215.4 " is then with cunning Mountain flour is filling, and triphenyl phosphate, antimony oxide, aluminium hydroxide are fire retardant, and hydrogenation SBR is that main substrate is made into TPE, and hardly possible is full The low VOC environmental requirement of foot.
In addition there are also more reports to use rubber material, but rubber needs vulcanization crosslinking, and recycling is difficult, economy and production Low efficiency.
The halogen-free flameproof of thermoplastic elastomer (TPE) is the problem of a puzzlement industry, and halogen-free flameproof effect is mainly by carbon Covering and generation non-flammable gases dilution cooling realization are fire-retardant, but elastomer is easy " flashing over ", traditional magnesium hydroxide and hydrogen-oxygen It is very big to change aluminium additive amount, influences elastomer performance, in addition for realize low VOC, low smell generally cannot using phosphoric acid ester and The fire retardant of low melting point, it is necessary to use powder solid fire retardant, addition also has negative effect to wear-resisting.It sees with practical conditions, Wearing layer, enhancement layer and back carpet veneer have negative interaction to the flame retardant property of halogen-free flame-retardant system in its structure.
