Description
Technical field
The present invention relates to organic silicon fibre retardant technical field, specifically a kind of fire retardant based on silicone resin.
Background technology
Current macromolecular material superpolymer has been widely used in industrial production and daily life.Most of macromolecular material superpolymer is all inflammable, in flammable solid fire, occupy dominant position.Therefore the macromolecular material superpolymer of flame retardant type becomes a primary study direction of Material Field, and additive flame retardant is the most widely used at present.At present, additive flame retardant year usage quantity more than 1,000,000 tons.Wherein: (1) does not produce toxic gas and corrosive gases although inorganic combustion inhibitor is as fire-retardant in magnesium hydroxide and aluminium hydroxide have simultaneously with when pressing down cigarette effect and burn, and has a strong impact on by the physics of fire retardant material, mechanical property and processing characteristics because required addition is comparatively large.(2) although organic halogenated flame retardant has the features such as high flame retardant efficiency and high performance-price ratio, because its HX playing fire retardation is poisonous corrosive gases, be harmful to environment and human body, therefore its Application Areas has been restricted, and oneself is eliminated gradually.(3) halogen-free flame retardants (IFR) has low cigarette, the advantage such as nontoxic, and IFR for essential core composition, can produce cooperative flame retardant effect with phosphorus, nitrogen, carbon when being heated; Composite IFR usually with ammonium polyphosphate (APP) for acid source, with trimeric cyanamide (MEL) for whipping agent, with tetramethylolmethane (PER) for char-forming agent, by the carbonaceous foam layer that can generate even compact during high heat, can heat insulation, oxygen barrier, press down cigarette, anti-molten drop, there is good flame retardant properties; But this based flame retardant mostly is hydrophilic, with polymer base poor compatibility, and required addition is comparatively large, have impact on the physicals of flame retarded polymeric material superpolymer, therefore can not meet the demand of macromolecular material.(4) organic silicon fibre retardant is that the one of development in recent years is new and effective, low toxicity, anti-molten drop, eco-friendly halogen-free flame retardants, is also a kind of charcoal becoming smoke suppressant.Organic silicon fibre retardant, outside the flame retardant properties of giving base material excellence, can also improve the processing characteristics of base material, resistance toheat etc.; But because price is more expensive, application is also subject to a definite limitation.
According to Britain's " polymer degradation is with stable " (PolymerDegradationandStability, 90:523-534,2005) introduce, add the polypropylene flame redardant obtained by the expanding fire retardant be made up of trimeric cyanamide ammonium sulfate and tetramethylolmethane accounting for system total mass 40% and just can reach UL-94V0 rank, but the mechanical property of material such as tensile strength and breaking tenacity can be caused to decline because the total amount of adding expanding fire retardant is comparatively large.
According to the U.S.'s " polymer science magazine " (JournalofPolymerScience, partA:Ploymerchemistry42:6163-6173,2004) introduce, during by organo montmorillonite and expansion type flame retardant synergistic polypropylene flame redardant, when to account for system total mass percentage composition ratio be 4% to organo montmorillonite quality, the heat release rate of polypropylene flame redardant obviously can be reduced; But along with the increase (after more than 4%) of organo montmorillonite content aggravates because reuniting, its flame retardant effect declines on the contrary.
Shortcoming at present for silicone resin is: its poor heat resistance, and its surface is more sticky after hardening.In addition, in order to effectively silicone resin is used as LED sealing agent, the performance of such as high refrangibility, splitting resistance, surface hardness, bond strength and thermal-shock resistance must be guaranteed.
In addition, although existing employing melt-blending process obtains have the characteristics such as LSZH and resistance to molten containing nitrogen-phosphorus expansion fire retardant or the flame-retardant polymer containing nitrogen-phosphorus expansion fire retardant and retardant synergist, but flame retardant effect is still not ideal enough, resistance to molten property need to improve, also because the flame retardant amount of required interpolation can make comparatively greatly the mechanical property of material such as tensile strength, breaking tenacity decline, and production cost is higher.
