Description
Technical field
The present invention relates to the flame-retarded technology field, particularly a kind of a kind of halogen-free flame retardants and preparation method who is applicable in general-purpose plastics and the engineering plastics processing.
Background technology
Fire retardant is widely used in the middle of general-purpose plastics, engineering plastics and polyblend, the urethane etc. as one of most important chemical industry additive.Halogen containing flame-retardant has advantages such as flame retarding efficiency height, addition are few; Still be widely used at present; But because halogen containing flame-retardant, the particularly brominated flame retardant amount of being fuming in combustion processes is big, burning discharges a large amount of poisonous and mordant gases, thereby brought huge environmental protection pressure.At present, the RoHS of European Union instruction banned use of PBDE, PBBs electric and household electrical appliance in, also there are similar regulation in the Canada and the U.S..External famous enterprise such as Sony, HP etc. have clearly stipulated its electronic and electrical equipment content of halogen.Can predict, not far future, halogen flame was inevitablely replaced by the New-type halide-free environmental protection fire retarding agent, and will progressively withdraw from the market.
Organic phosphorus flame retardant is topmost in the market halogen-free flame retardants kind, usually is used in the middle of engineering plastic alloy and the urethane, has little, the advantage such as low of being fuming of toxicity.But the organic phosphorus flame retardant burning can discharge mordant acidic substance; Base material and surrounding environment are had bigger corrodibility, and this based flame retardant will reach the flame retardant effect of UL V0, addition will reach more than 10%; And then cause the thermotolerance of polyblend to reduce; The toughness variation, physical strength descends, so its range of application has also received certain restriction.
Advantages such as that inorganic combustion inhibitor has is cheap, fire-retardant, smoke elimination are the fire retardants of one type of environmental protection, often are used in the polyolefine of halogen-free flameproof.But the shortcoming that this based flame retardant has or not method to overcome; That will reach fire-retardant preferably rank exactly, and necessary heavy addition is usually greater than 50%; This just causes plastics proportion seriously to raise; And then the little advantage of forfeiture proportion, cause poor processability simultaneously, the field that toughness reduces and then limited its application.
Organic silicon fibre retardant is a kind of emerging environmental protection fire retarding agent, has advantages such as nontoxic, non-corrosiveness of when burning, low cigarette, thermal value are low, also is one of halogen-free environment-friendly flame-proof agent that has most future.And organic silicon fibre retardant can also improve the surface property of mechanics, processing characteristics and the polymer materials of polymkeric substance to a certain extent.But, as a kind of organic silicon fibre retardant, also have cost an arm and a leg, flame retarding efficiency is not high, addition is big deficiency, therefore be necessary to develop a kind of moderate cost, the higher organic silicon fibre retardant of efficient.
Summary of the invention
One of technical issues that need to address of the present invention provide a kind of existing good flame-retardance ability, do not reduce the plastics of polymer machinery performance and processing characteristics again and use halogen-free flame retardants.
The technology contents that solves the problems of the technologies described above is following:
Plastics of the present invention with halogen-free flame retardants mainly by 20～80 parts of WHITE CARBON BLACKs, the surface treatment agent of 10～80 parts of organopolysiloxane and 1～4 part, the organic MQ silicone resin of 10-80 part is prepared from.
Preferably; Said thermal silica; It carries out surface treatment through surface treatment agent; Surface treatment agent can be hydroxy silicon oil, aminomethyl phenyl silicon diol, Diphenylsilanediol, phenyltrimethoxysila,e, phenyl triethoxysilane, phenylbenzene diethoxy silane, dimethoxydiphenylsilane, methyl ethoxy silane etc., more preferably hydroxy silicon oil, aminomethyl phenyl silicon diol or Diphenylsilanediol.
