Title:
GRAPHENE-BASED ORGANIC SILICON POROUS NANO MATERIAL AND PREPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/135379
Kind Code:
A1
Abstract:
A graphene-based organic silicon porous nano material and a preparation method therefor. The material is composed of a component A and a component B in a weight ratio of 1-2:1. The component A comprises the following raw materials in parts by weight: 10-50 parts of methyl vinyl polysiloxane; 5-20 parts of methyl hydrogen-containing polysiloxane; 0.1-5 parts of a chain extender; 0.1-10 parts of a parting agent; 5-30 parts of graphene; 0.05-2 parts of a structuring control agent; 0.05-2 parts of a silane coupling agent; 0.01-1 parts of a silicone-based inhibitor; and 0.5-5 parts of a foaming agent. The component B comprises the following raw materials in parts by weight: 10-20 parts of methyl vinyl polysiloxane; 10-30 parts of a methyl vinyl MQ silicone resin; 0.1-10 parts of a parting agent; 5-30 parts of graphene; 0.05-2 parts of a structuring control agent; 0.01-1 parts of a catalyst; and 0.5-5 parts of an activator. The described graphene-based organic silicon porous nano material is lightweight and viscoelastic and has fine and uniform cross-sectional pores; a graphene nano film interacts with an organic silicon material matrix; a bonding substrate is firm and has excellent compression resistance, impact resistance and thermal stability; moreover, the described material is suitable for lightweight application scenarios, such as sealing and shock absorption, microwave absorption, electromagnetic shielding and heat dissipation protection.
