Abstract

The invention discloses a graphene natural rubber polymer composite foaming material for old people's shoe soles and a preparation method thereof. 12 parts, 4-6 parts of nano medium, 4-5 parts of phenylene ether silanediol, 2.5-3.5 parts of hydroxyl-terminated polydimethylsiloxane, 2-2.5 parts of graphene, 1.5-2 parts of zinc oxide, hard 2.5-3 parts of fatty acid, 2-2.4 parts of zinc stearate, 2-2.5 parts of crosslinking agent, 1.8-2.2 parts of foaming agent, 4-5 parts of lubricant. The present invention is composed of selected raw materials, and optimizes the content of each raw material, so that the obtained graphene natural rubber polymer composite foam material for old people's shoes has good anti-slip effect; high tensile strength, good mechanical properties and good durability; and Low density, ultra-light; especially suitable as sole material for the elderly.

Description

technical field [0001] The invention relates to the technical field of polymer composite foaming materials, in particular to a graphene natural rubber polymer composite foaming material for elderly shoe soles and a preparation method thereof. Background technique [0002] Most of the present various soles are made of EVA or rubber materials, the cost is relatively controllable, and properties such as elasticity and hardness can be adjusted according to needs, which has basically met people's requirements. [0003] Natural rubber is the variety with the best coordination of physical and mechanical properties and process performance among rubber materials. It has been widely used in daily life, medical and health care, transportation, agriculture, scientific experiments, national defense and other fields. With the development of society, people have put forward higher requirements on the performance of products, such as: rubber foam soles, traditional rubber foam soles are hea...
