Title:
LIGHTWEIGHT ORGANIC COMPOSITE MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/199134
Kind Code:
A1
Abstract:
The present invention relates to a lightweight organic composite material and a preparation method therefor. Specifically disclosed is an organic composite material based on thermally expandable microspheres. The organic composite material comprises a continuous phase skeleton formed by interconnection of sphere walls of the thermally expandable microspheres, and an organic material with which outer gaps of the thermally expandable microspheres are filled. The organic material is selected from a low-viscosity fluid, an elastomer, and a thermosetting polymeric material. The organic composite material based on thermally expandable microspheres is obtained by means of the following method: mixing the thermally expandable microspheres with the low-viscosity fluid, the elastomer, and the thermosetting polymeric material, or with precursors forming the low-viscosity fluid, the elastomer, and the thermosetting polymeric material, to obtain a semi-solid or liquid mixture; and injecting the mixture into a closed container and heating same such that the thermally expandable microspheres are expanded and the sphere walls of the thermally expandable microspheres are connected to form the continuous phase skeleton. The material has certain compression performance, and is light in weight, excellent in performance, and wide in application; and the preparation method is simple, convenient, and easy to implement.
