抗紫外线V0级阻燃ABS颗粒

ABS树脂燃烧机理非常复杂，由于所用原料种类、配比、工艺条件、生产方法的多样化，ABS树脂的实际组成差别很大，其燃烧性能也不同。一般来说，随着丁二烯组成的增加，树脂透明度降低，可燃性增加。这是由于聚丁烯相中存在取代碳原子，这有助于氧从丁二烯中吸收氢，并引发氧化，加速ABS的降解。也有人提出，ABS热氧老化可以用丙烯腈-丁二烯和丁二烯-苯乙烯共聚物的热降解来解释，并且在丙烯腈-丁二烯共聚物的热解产物中未发现丙烯腈HCN的特定产物，这是由丁二烯部分的裂解引起的，而丁二烯部分的裂解是由与HCN的快速反应引起的。ABS树脂和自然界中的其他聚合物一样，在燃烧过程中会产生特别活跃的自由基HO，而HO的浓度是决定燃烧速率的关键。当聚合物和HO相遇时，聚合物自由基和水的生成，在氧气存在的情况下，HO自由基的生成，可以让反应继续进行，最终生成CO2和H2O

Anti-UV V0 Grade Flame Retardant ABS Granule

Product Details

Anti-UV V0 Grade Flame Retardant ABS Granule

ABS resin combustion mechanism is very complex, because of the type of raw materials used, proportion, process conditions, production methods of diversification, the actual composition of ABS resin varies greatly, its combustion performance is also different. Generally with the increase of butadiene composition, resin transparency is reduced, flammability increases. This is due to the presence of substitute uncle carbon atoms in the polybutyene phase, which help oxygen to take hydrogen from butadiene and trigger oxidation to accelerate the degradation of ABS. It has also been suggested that ABS thermal-oxygen aging can be explained by the thermal degradation of acrylonitrile-butadiene and butadiene-styrene copolymers, and that no specific product of acrylonitrile HCN has been found in the pyrolysis products of acrylonitrile-butadiene copolymers, which is caused by the thalysis of the butadiene part, which is caused by a rapid reaction with HCN. ABS resins, like other polymers in nature, produce particularly active free radical HO during combustion, and the concentration of HO is the key to determining the combustion rate. When the polymer and HO meet, the production of polymer free radicals and water, in the presence of oxygen, the production of HO free radicals, can allow the reaction to continue, and finally the production of CO2 and H2O.
