无机色粉对阻燃ABS性能影响

摘要

主要研究了在TBBPA(四溴双酚-A)阻燃丙烯腈-丁二烯-苯乙烯共聚物(ABS)中分别填充钛白、铁红和炭黑3种无机色粉后的性能,结果表明,填充3种色粉均可以使ABS的密度升高,铁红和炭黑的加入使ABS弯曲强度和弯曲模量升高,炭黑和钛白粉降低了ABS熔体流动速率,3种无机色粉填充阻燃ABS的阻燃性能均达到UL94V-0级,综合性能优异.%The performance of the TBBPA flame retarded ABS filled by three kinds of inorganic color toners of TiO2, Fe2O3, and carbon black (C), was mainly studied. The results show that all the three kinds of inorganic color toners increase the flame-re-tardant ABS density. Fe2 O3 and C increase the flexural strength and modulus of ABS. C and TiO2 decrease the melt index of ABS. The flame retardancy of flame-retardant ABS filled by three kinds of inorganic color toners reaches UL94V-0 level, and the comprehensive properties are excellent.
