Abstract

The invention discloses a vitrified dilatant polymer foam hybrid material. The hybrid material is characterized by comprising a dilatant polymer and polymer foam particles, wherein the dilatant polymer is at least selected from a vitrified dilatant polymer; the polymer foam particles are compounded with the dilatant polymer and other optional components to form the hybrid material. The hybrid material has the characteristics of low density, heat insulation, sound insulation, buffering, shock absorption, dilatancy, slow resilience and the like, and can be widely applied to manufacturing of packaging materials, building materials, impact-resistant protective materials, shock absorption materials, buffering materials, silencing materials, heat preservation materials, shape memory materials, electronic and electric appliance materials, medical supplies and the like.

Description

technical field [0001] The invention relates to the field of intelligent materials, in particular to a vitrified dilatant polymer foam hybrid material. Background technique [0002] With the development of society, the demand for lightweight, insulating, shock-resistant and sound-absorbing materials in the consumer market has gradually increased, and the output and types of foam materials have increased sharply, making it a very important type of polymer products. Compared with the unfoamed material, the inside of the foam material is composed of a large number of cells with stable size and structure, which makes it have the advantages of light weight, heat insulation, sound insulation, high specific strength, cushioning and shock absorption, and wear resistance. Therefore, in packaging Industry, industry, agriculture, transportation, military industry, aerospace industry and daily necessities are widely used. [0003] Traditional foam varieties include polyurethane foam, p...
