一种ABS复合材料ABS composite material
技术领域Technical field
本发明涉及工程塑料技术领域,具体涉及一种ABS复合材料。The invention relates to the technical field of engineering plastics, in particular to an ABS composite material.
背景技术Background technique
ABS树脂是微黄色固体,密度约为1.04g/cm
3,由于它将丙烯腈、丁二烯、苯乙烯三种不同材料的性能有机地统一起来,兼具成型性、刚性、韧性,综合性能优良,应用广泛。ABS适用于家用电器制品,如电视机外壳、冰箱内衬、吸尘器等,以及仪表、电话、汽车工业用塑料制品。
ABS resin is a yellowish solid with a density of about 1.04g/cm 3. Because it organically unifies the properties of three different materials, acrylonitrile, butadiene, and styrene, it has moldability, rigidity, toughness, and comprehensive performance. Excellent and widely used. ABS is suitable for household appliances, such as TV housings, refrigerator linings, vacuum cleaners, etc., as well as plastic products for instruments, telephones, and the automotive industry.
阻燃ABS是ABS改性的重要方向之一,它是针对普通ABS树脂容易燃烧这一缺点而开发的。阻燃等级由HB、V-2、V-1、V-0、5VB向5VA逐级递增。其中5V测试要求对样品进行五次5秒的燃烧测试后,余焰或余燃在30秒内熄灭,滴落不可引燃棉花,5VA还要求样品不允许被烧穿,样条越薄,越不容易达到。Flame retardant ABS is one of the important directions of ABS modification. It is developed in response to the shortcoming of ordinary ABS resin that is easy to burn. The flame retardant grade increases from HB, V-2, V-1, V-0, 5VB to 5VA. Among them, the 5V test requires the sample to be burned five times for 5 seconds, and the afterflame or afterflame is extinguished within 30 seconds. The dripping cannot ignite cotton. 5VA also requires that the sample is not allowed to burn through. The thinner the spline, the more Not easy to reach.
常规改性方式,如专利CN201310225994、CN201310430476公开了阻燃ABS和阻燃PC/ASA合金,溴系或磷系阻燃,但达到阻燃效果的样条厚度较大,一般在3.0mm以上。Conventional modification methods, such as patents CN201310225994 and CN201310430476, disclose flame-retardant ABS and flame-retardant PC/ASA alloys, brominated or phosphorus-based flame retardants, but the thickness of the spline that achieves the flame retardant effect is large, generally above 3.0mm.
专利CN200810066901、CN201611212463公开了PVC/ABS合金,可以达到高阻燃等级,但由于PVC热稳定性较差,加工窗口很窄,限制了其应用。Patents CN200810066901 and CN201611212463 disclose PVC/ABS alloys, which can achieve high flame retardant grades, but due to poor thermal stability of PVC, the processing window is very narrow, which limits its application.
专利CN201210470130、CN201310743041公开了高阻燃等级的ABS及其合金,但由于玻纤/碳纤的加入,导致其外观不佳。The patents CN201210470130 and CN201310743041 disclose high flame retardant ABS and its alloys, but due to the addition of glass fiber/carbon fiber, its appearance is not good.
专利CN201480014209公开了一种填充的聚碳酸酯组合物,阻燃剂为双酚A一双(二苯基磷酸酯)复配大量的聚四氟乙烯,以硅灰石颗粒、氧化铝颗粒或者玻璃纤维及其混合物为填充,但最高只能做到2.3mm 5VA。Patent CN201480014209 discloses a filled polycarbonate composition, the flame retardant is bisphenol A-bis (diphenyl phosphate) compounded with a large amount of polytetrafluoroethylene, wollastonite particles, alumina particles or glass fibers And its mixture is filled, but the highest can only be 2.3mm 5VA.

一般而言,拉伸强度大于38MPa,弯曲强度大于56MPa,IZOD缺口冲击强度大于12kJ/m
2,光泽度大于80时,材料的综合力学性能较优,其中冲击强度为最关键的因素。从表6、7的数据可以看出,本发明所述ABS复合材料的阻燃性能较好,并具有较好的抗冲击强度。从实施例7和对比例1的比较可以看出,采用丁二烯的重量百分含量为28~35%的阻燃效果和力学性能优于较低丁二烯含量的ABS树脂。从实施例7和对比例2的比较可以看出,采用高粘SAN树脂比普通的SAN树脂的阻燃等级更高。从实施例7和对比例3的比较可以看出,采用KF-1的阻燃效果比一般的阻燃协效剂更好。从实施例7和对比例4的比较可以看出,当无机填充物的长径比大于5:1时,阻燃效果更佳。从实施例4~9的比较可以看出,随着无机填充物含量的增加,ABS树脂含量的降低,ABS复合材料的阻燃等级增加,拉伸强度、弯曲强度和缺口冲击强度有所下降,当无机填充物的含量大于12重量份时,阻燃等级增加不明显,韧性下降,因此优选无机填充物的含量为8~12重量份。从实施例5、7、10~13的结果可以看出,随着高粘SAN树脂含量的增加,抗冲击强度有所下降,但是拉伸强度和弯曲强 度有所上升,当高粘SAN树脂大于3重量份时,能满足冲击性能和强度的平衡。实施例7和实施例14、15的比较可以看出,增韧剂能改善高粘SAN树脂带来的抗冲击强度下降问题。
Generally speaking, when the tensile strength is greater than 38MPa, the bending strength is greater than 56MPa, the IZOD notch impact strength is greater than 12kJ/m 2 and the gloss is greater than 80, the comprehensive mechanical properties of the material are better, and the impact strength is the most critical factor. It can be seen from the data in Tables 6 and 7 that the ABS composite material of the present invention has better flame retardancy and better impact resistance. From the comparison between Example 7 and Comparative Example 1, it can be seen that the flame retardant effect and mechanical properties of butadiene with a weight percentage of 28 to 35% are better than that of ABS resin with a lower butadiene content. It can be seen from the comparison between Example 7 and Comparative Example 2 that the high-viscosity SAN resin has a higher flame retardant grade than the ordinary SAN resin. It can be seen from the comparison between Example 7 and Comparative Example 3 that the flame retardant effect of using KF-1 is better than the general flame retardant synergist. It can be seen from the comparison between Example 7 and Comparative Example 4 that when the aspect ratio of the inorganic filler is greater than 5:1, the flame retardant effect is better. As can be seen from the comparison of Examples 4 to 9, as the content of the inorganic filler increases, the content of the ABS resin decreases, the flame retardant grade of the ABS composite increases, and the tensile strength, bending strength, and notch impact strength decrease. When the content of the inorganic filler is greater than 12 parts by weight, the increase in the flame retardant grade is not obvious, and the toughness decreases, so the content of the inorganic filler is preferably 8 to 12 parts by weight. It can be seen from the results of Examples 5, 7, 10 to 13 that as the content of the high-viscosity SAN resin increases, the impact strength decreases, but the tensile strength and bending strength increase. When the high-viscosity SAN resin is greater than When it is 3 parts by weight, it can meet the balance of impact performance and strength. It can be seen from the comparison between Example 7 and Examples 14 and 15 that the toughening agent can improve the problem of reduction in impact strength caused by the high-viscosity SAN resin.
表8 实施例16~22试样的性能测试数据Table 8 Performance test data of the samples of Examples 16 to 22
从表6、8中实施例7、16~22的比较可以看出,当三(三溴苯氧基)三嗪与溴化环氧复配作为阻燃剂时能的阻燃效果较好,尤其是当三(三溴苯氧基)三嗪与溴化环氧的重量之比为:三(三溴苯氧基)三嗪:溴化环氧=1:4~4:1时,阻燃效果更好。发明人采用同样的方法对三(三溴苯氧基)三嗪与十溴二苯乙烷复配做了相关试验,结果表明当三(三溴苯氧基)三嗪与十溴二苯乙烷复配作为阻燃剂时能的阻燃效果较好,尤其是当三(三溴苯氧基)三嗪与十溴二苯乙烷的重量之比为:三(三溴苯氧基)三嗪:十溴二苯乙烷=1:4~4:1时,阻燃效果更好。It can be seen from the comparison of Examples 7, 16 to 22 in Tables 6 and 8 that when tri(tribromophenoxy)triazine and brominated epoxy compound are used as flame retardants, the flame retardant effect is better, Especially when the weight ratio of tris(tribromophenoxy)triazine to brominated epoxy is: tris(tribromophenoxy)triazine: brominated epoxy=1:4~4:1, the resistance Burning effect is better. The inventors used the same method to test the compound of tris(tribromophenoxy)triazine and decabromodiphenylethane. The results showed that when tris(tribromophenoxy)triazine and decabromodiphenylethyl When the compound is used as a flame retardant, the flame retardant effect is better, especially when the weight ratio of tris(tribromophenoxy)triazine to decabromodiphenylethane is: tris(tribromophenoxy) Triazine: decabromodiphenylethane = 1:4 ~ 4:1, the flame retardant effect is better.
表9 实施例22~23试样的性能测试数据Table 9 Performance Test Data of Examples 22 to 23 Samples
从表6、9中实施例6、22、23的比较可以看出,当增韧剂由球形的高胶粉更换为线型或星型SBS或SEBS时,复合材料的阻燃效果更好。It can be seen from the comparison of Examples 6, 22, and 23 in Tables 6 and 9 that when the toughening agent is changed from spherical high rubber powder to linear or star SBS or SEBS, the flame retardant effect of the composite material is better.
