Abstract

The invention discloses an ABS (acrylonitrile-butadiene-styrene) resin / nano inorganic particle composite foaming material which comprises the following components in parts by weight: 90-100 parts of ABS, 0-10 parts of nano inorganic particle, 10-20 parts of foaming agent, 90-180 parts of POE-g-GMA and 5-10 parts of foaming promoter. According to the invention, the nano inorganic particle is added into the ABS; and in the preparation of the foaming material, the nano inorganic particle can achieve heterogeneous nucleation action on one hand, and nano organic montmorillonite is evenly dispersed in the ABS matrix in the intercalation and delamination form to reduce the viscosity of the melt on the other hand, so that the nano inorganic particle / ABS resin microporous foaming material can achieve favorable foaming effect in a wide process range, and the prepared foaming material is small in average cell diameter, uniform in cell size distribution and high in cell density.

Description

technical field [0001] The invention relates to an ABS resin, nano inorganic particle composite foaming material and a preparation method thereof. Background technique [0002] As one of the five major synthetic resins, ABS resin has good impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties. While maintaining the above excellent properties, microcellular foamed materials also have the characteristics of low apparent density, light weight and tough structure. They are widely used in industrial fields such as machinery, automobiles, electronic appliances, instrumentation, textiles and construction. An engineering plastic with a wide range of uses. The performance of foamed materials, whether mechanical, thermal, electrical or thermodynamic, is closely related to the apparent density, average cell diameter, cell size distribution, cell density and other parameters of the foamed material. At present, the methods that can...
