Description
Technical field
The present invention relates to a technological invention in the industrial circles such as electrical equipment, electronics, automobile, be specially a kind of halogen-free low-smoke flame-proof ABS functional agglomerate and complete processing, be applied to fields such as household electrical appliance, electronics, building, have fire-retardant, press down cigarette, Halogen, functional characteristics such as nontoxic, be a kind of novel environment-friendly polymer-function material.
Background technology
ABS resin is a kind of engineering plastics with advantages such as excellent mechanical performances, chemical proofing and processing fluidities, be widely used in fields such as electrical equipment, Communication Equipment, automotive industry, and the market requirement increases constantly.The plastic master batch auxiliary agent can be simplified technology simultaneously, improves mixing quality, reduces dust from flying.But the oxygen index of ABS resin only is 18.3-20.0 (less than 21), belongs to inflammable material, has therefore limited its application.Therefore, giving the ABS flame-retarding characteristic has important practical significance to its Application Areas of further expansion.Because many salient featuress such as mechanical property, heat-drawn wire, melt flow rate (MFR) and the light stability etc. of flame-proof ABS all can be had a strong impact on because of the adding of fire retardant.So although the flame-retardant system that is used for ABS of bibliographical information is a lot, the fire retardant of industrial production flame-proof ABS is still bromide fire retardant at present.
Generally adopt at present the composite flame retardant system of Poly Brominated Diphenyl Ethers/antimonous oxide, but, limited its application in some occasions because of Halogen.Domestic also have employing magnesium hydroxide/aluminium hydroxide halogen-free flame-retardant system, but will reach flame retardant properties, and addition is big, destroys bigger to the physicals and the processing characteristics of material.In reinforced ABS material, generally adopt glass to strengthen at present, but flame retardant properties does not often reach requirement.
Perfect along with the enhancing of people's environmental consciousness and environmental regulation, the development of Halogen, low halogen fire retardant material and exploitation have become an important development direction of flame retardant area.Inorganic compounding flame-retardant system based on aluminium hydroxide and magnesium hydroxide is one of current the most frequently used halogen-free flame-retardant system, it is with cheap, and have filling, fire-retardant, press down function such as cigarette and be widely used in the polymer materials, but lower flame retarding efficiency makes it when giving the flame-retarding characteristic of polymer materials, the mechanical property of badly damaged material and processing characteristics.Overcoming the most frequently used means of this shortcoming is to add retardant synergist and improve the dispersion effect of fire retardant in polymkeric substance.As add red phosphorus synergy, add glass enhancing etc.But this means are restricted the use face of material, when requiring as the color to material, use red phosphorus to be restricted.
Develop a kind of fire-retardant reinforced ABS material, the low low smoke performance of the amount of the being fuming when electric property that its existing polyolefine had, mechanical property, weather-resistant property, burning has good flame retardancy again simultaneously, then has great importance.At present flame-proof ABS present situation, Dalian Samat Chemicals Co., Ltd. began to have carried out technology development work in 2003, set up the experimental test center, and at the characteristics of fire-retardant magnesium salt whisker, that is: the characteristic of existing inorganic combustion inhibitor, glass enhanced characteristics are arranged again, successfully developed fire-retardant reinforced ABS functional agglomerate.
