Abstract

The invention belongs to the technical field of high polymer materials and discloses a poly(butylene succinate) ionomer microcellular foaming material and a preparation method thereof. According to the method, poly(butylene succinate) ionomer serves as a raw material, supercritical CO2 serves as a foaming agent, and the poly(butylene succinate) ionomer microcellular foaming material is achieved in a mode of intermittent foaming. According to the method, the shortcoming that poly(butylene succinate) ionomer melt is low in strength and difficult to foam is effectively overcome, the technical problems that existing products are high in opening percentage and large and uneven in cell size, and cell quality is difficult to regulate are solved, the cell quality of the poly(butylene succinate) foaming material is improved, the cell size and cell density of the foaming material are easy to regulate, and the foaming material which is small in material density, high in foaming ratio, small in cell size and high in cell density is manufactured. The supercritical CO2 serves as the foaming agent, and the poly(butylene succinate) ionomer microcellular foaming material has the advantages of low cost, easiness in operation control, no poison and no pollution and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a polybutylene succinate ionomer microporous foaming material and a preparation method thereof. Background technique [0002] Due to the large number of micron-sized cells inside the polymer microcellular foaming material, it can significantly reduce the quality of polymer products without significantly reducing the mechanical properties of the material, effectively reducing the amount of plastic used and reducing costs. It has high impact strength, With the advantages of light weight, low thermal conductivity and low dielectric constant, it is widely used in construction, packaging, automobile, military, aerospace and other fields. [0003] Supercritical CO 2 Because of its low price, easy operation, non-toxic and non-polluting, etc., it has become a hot spot in industrial production and scientific research in the field of foaming, and has become the most promising al...
