Abstract

The invention provides a novel environment-friendly foamed material as well as a preparation method and a foaming process thereof. The novel environment-friendly foamed material comprises the following raw materials in parts by weight: 60-95 parts of a substrate resin, 5-9 parts of graphene, 10-15 parts of NaHCO3, 12-16 parts of ethylene glycol, 8-12 parts of glycerol triacetate and 3-6 parts of liquid nitrile rubber. A foamed material made of the novel environment-friendly foamed material provided by the invention has the advantages of being high in strength, sufficient in toughness, good inelasticity, good in anti-electrostatic resistance, uniform in foaming aperture and small in powder peeling; the raw materials are relatively small in environment influence, so that the material has certain environment protection properties, can be applied to different situations, is capable of meeting requirements of different scenes and has wide market prospects.

Description

technical field [0001] The invention relates to the field of environment-friendly foaming materials, in particular to a novel environment-friendly foaming material, a preparation method and a foaming process thereof. Background technique [0002] Foaming materials are used more and more widely. In the actual production process, general resin materials will be foamed by gas foaming process. However, due to some gases (such as CO 2 ) has a low boiling point and is difficult to effectively control, so that the cell size of the prepared foam material is uneven, and the cell aperture is small in some places, and the cell aperture is large in some places. This has a great impact on the quality and stability of the mechanical properties of the foamed material produced. Contents of the invention [0003] In order to solve the problems of uneven cell size and low quality and mechanical properties of the foamed material produced by the foaming process mentioned in the above backgro...
