Abstract

The disclosure belongs to the technical field of heat insulation materials, and discloses an in-situ microfibrillated reinforced polymer composite heat insulation foam material as well as a preparation method and application thereof. This disclosure adopts a polypropylene matrix, a fiber-forming polymer, an elastomer and an antioxidant as a foam material. The foaming material is subjected to a primary melt blending process and a hot stretching process first, then subjected to a secondary melt blending process and cooling granulation and subjected to a pressing process, and a composite board is obtained. The composite board is subjected to supercritical fluid foaming process, and a composite heat insulation foam material is obtained.
