一种陶瓷/ABS超强超韧复合材料及在电气领域的应用A ceramic/ABS super-strong and super-tough composite material and its application in the electrical field

技术领域technical field

本发明涉及ABS技术领域,具体涉及一种陶瓷/ABS超强超韧复合材料及在电气领域的应用。The invention relates to the technical field of ABS, in particular to a ceramic/ABS super-strong and super-tough composite material and its application in the electrical field.

背景技术Background technique

ABS塑料是丙烯腈(A)、丁二烯(B)、苯乙烯(S)三种单体的三元共聚物,三种单体相对含量可任意变化,制成各种树脂。ABS兼有三种组元的共同性能,A使其耐化学腐蚀、耐热,并有一定的表面硬度,B使其具有高弹性和韧性,S使其具有热塑性塑料的加工成型特性并改善电性能。因此ABS塑料是一种原料易得、综合性能良好、价格便宜、用途广泛的“坚韧、质硬、刚性”材料。ABS塑料在机械、电气、纺织、汽车、飞机、轮船等制造工业及化工中获得了广泛的应用。ABS plastic is a terpolymer of three monomers, acrylonitrile (A), butadiene (B) and styrene (S). The relative content of the three monomers can be changed arbitrarily to make various resins. ABS has the common properties of three components, A makes it resistant to chemical corrosion, heat resistance, and has a certain surface hardness, B makes it have high elasticity and toughness, S makes it have the processing and molding characteristics of thermoplastics and improve electrical properties . Therefore, ABS plastic is a kind of "tough, hard and rigid" material with easily available raw materials, good comprehensive performance, low price and wide application. ABS plastic has been widely used in machinery, electrical, textile, automobile, aircraft, ship and other manufacturing industries and chemical industry.

由于ABS的热导率低,难以用于需要散热的配件。为开发导热ABS材料,必须对现有ABS进行改性。ABS具有优良的综合性能,近年来通用级ABS的市场竞争日趋激烈,开发导热ABS材料,可以扩大其在电子电器外壳方面的应用,提高产品的附加值。Due to the low thermal conductivity of ABS, it is difficult to use for accessories that require heat dissipation. In order to develop thermally conductive ABS materials, existing ABS must be modified. ABS has excellent comprehensive properties. In recent years, the market competition of general-purpose ABS has become increasingly fierce. The development of thermally conductive ABS materials can expand its application in electronic and electrical enclosures and increase the added value of products.

提高ABS导热率的方法一般为混入导热填料,在ABS基体中形成有效的导热通路,这就要求导热填料在ABS的填充量要大,一般需要达到50wt%的填充量以上导热率才会有显著的提升,但是同时应力集中的问题也会导致ABS的强度和韧性下降,并且加工性也会变差,不利于工业生产。The method to improve the thermal conductivity of ABS is generally to mix thermal conductive fillers to form an effective thermal conduction path in the ABS matrix. However, at the same time, the problem of stress concentration will also cause the strength and toughness of ABS to decrease, and the processability will also deteriorate, which is not conducive to industrial production.

发明内容SUMMARY OF THE INVENTION

为了克服现有技术中存在的缺点和不足,本发明的目的在于提供一种陶瓷/ABS超强超韧导热复合材料及其制备方法。In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the present invention is to provide a ceramic/ABS super-strong and super-tough thermally conductive composite material and a preparation method thereof.

与对比例1的硅烷偶联剂改性处理相比,本发明实施例3的ABS材料具有更好的力学性能,但导热性能较差,说明对比例1中的导热填料填充量较大,即使经过硅烷偶联剂处理,在基体中依然不能实现较好的分散,因而力学性能较差,但也因此对比例1中填料容易团聚,彼此接触形成导热通路,因此导热性能表现更好;与对比例2相比,本发明通过尼龙和氮化铝的超声分散可以较好地解决氮化铝的团聚问题,力学性能也具有较好的表现,但由于尼龙在氮化铝之间形成间隔,不能形成较好的导热通路,因而最终制得的ABS材料导热性能较差。Compared with the silane coupling agent modification treatment of Comparative Example 1, the ABS material of Example 3 of the present invention has better mechanical properties, but poor thermal conductivity, indicating that the amount of thermally conductive filler in Comparative Example 1 is large, even if After being treated with silane coupling agent, it still cannot achieve good dispersion in the matrix, so the mechanical properties are poor, but the fillers in Comparative Example 1 are easy to agglomerate and contact each other to form a thermal conduction path, so the thermal conductivity performance is better; Compared with ratio 2, the present invention can better solve the problem of agglomeration of aluminum nitride by ultrasonic dispersion of nylon and aluminum nitride, and the mechanical properties also have better performance, but because nylon forms a gap between aluminum nitride, it cannot be A better thermal conduction path is formed, so the thermal conductivity of the final ABS material is poor.
