Description
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.
本发明的目的通过下述技术方案实现：The object of the present invention is achieved through the following technical solutions:
一种陶瓷/ABS超强超韧复合材料，包括如下重量份数的原料：A ceramic/ABS super-strong and super-tough composite material, comprising the following raw materials in parts by weight:
所述改性陶瓷的制备方法包括如下步骤：The preparation method of the modified ceramic comprises the following steps:
(1)将15-25重量份的PA6溶解于100重量份的甲酸中，形成尼龙溶液；(1) PA6 of 15-25 parts by weight is dissolved in the formic acid of 100 parts by weight to form nylon solution;

本发明以氮化铝陶瓷作为主要导热填料，蒙脱土作为次要导热填料，提高ABS的导热性能。而为了导热填料在ABS均匀分散并且形成有效的导热通路，本发明通过溶剂再生，使得尼龙包覆氮化铝，改善了氮化铝与ABS的界面性能，此外，本发明还对尼龙进行蒙脱土插层改性，尼龙分子插入蒙脱土层间，形成复合材料，蒙脱土在尼龙中为氮化铝搭建了导热通路，从而避免尼龙阻隔降低导热性的问题；此外，本发明加入了相容剂有效改善PA6和ABS的界面性能，因而最终可以得到具有良好力学性能和导热性能的ABS材料。In the present invention, aluminum nitride ceramics are used as the main thermal conductive filler, and montmorillonite is used as the secondary thermal conductive filler to improve the thermal conductivity of ABS. In order to uniformly disperse the thermally conductive fillers in ABS and form an effective thermal conduction path, the present invention regenerates the solvent, so that nylon is coated with aluminum nitride, which improves the interface performance between aluminum nitride and ABS. In addition, the present invention also montmorillonizes nylon. Soil intercalation modification, nylon molecules are inserted between montmorillonite layers to form composite materials, and montmorillonite builds a thermal conduction path for aluminum nitride in nylon, thereby avoiding the problem of nylon blocking and reducing thermal conductivity; in addition, the present invention adds The compatibilizer can effectively improve the interface properties of PA6 and ABS, so ABS materials with good mechanical properties and thermal conductivity can be finally obtained.

In addition, the ABS used in the present invention is high-fluidity ABS, and when combined with the modified ceramics of the present invention, it can be used as a spray-free material, and the surface of the injection molded part is smooth and free of flow marks.
其中，所述蒙脱土的晶片行厚度为10-20nm，所述氮化铝的粒径为20-30nm，所述表面活性剂为烷基酚聚氧乙烯醚。Wherein, the thickness of the wafer row of the montmorillonite is 10-20 nm, the particle size of the aluminum nitride is 20-30 nm, and the surfactant is an alkylphenol polyoxyethylene ether.

The ceramic/ABS super-strong and super-tough thermally conductive composite material of the invention has good insulation and thermal conductivity, is especially suitable for the electrical field, and can be used for making products such as plugs, sockets, wiring boards and relays.

实施例3和对比例1-2的塑料制成试样，对试样分别进行拉伸强度、弯曲强度、冲击强度和导热系数的测试，测试标准分别为ASTM D-638、ASTM D-790、ASTM D-256、ASTMD5470，测试结果如下表：The plastics of Example 3 and Comparative Examples 1-2 were made into samples, and the samples were tested for tensile strength, flexural strength, impact strength and thermal conductivity respectively. The test standards were ASTM D-638, ASTM D-790, ASTM D-256, ASTMD5470, the test results are as follows:
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.
上述实施例为本发明较佳的实现方案，除此之外，本发明还可以其它方式实现，在不脱离本发明构思的前提下任何显而易见的替换均在本发明的保护范围之内。The above-mentioned embodiment is a preferred implementation scheme of the present invention.
