Problems solved by technology

The soft segment of polyurethane elastomer determines the flexibility and toughness of the material, and the hard segment determines the strength and rigidity of the material. However, there is an obvious phase separation between the soft and hard segment. Therefore, the pure polyurethane material prepared by conventional methods and formulas has relatively low rigidity, thermal conductivity and thermal stability. Poor performance, low friction coefficient but high wear, it needs to be modified to meet engineering requirements

Abstract

The invention relates to a bio-based porous carbon reinforced modification polyurethane composite material which comprises the following ingredients in parts by weight: 30-40 parts of polypropylene glycol, 28-36 parts of isophorone diisocyanate, 18-25 parts of 3,3'-dichloro-4,4'-diaminodiphenyl-methane, 1-20 parts of bio-based porous carbon and 3-10 parts of a coupling agent. In the composite material, the bio-based porous carbon is made by taking natural bamboos or bamboo shoots as a raw material, is simple in preparation process and can be produced industrially in large scale; the prepared polyurethane composite material has excellent tensile property, heat stability and friction-reducing and wear-resisting features, thereby having high production value and use value and being wide in market prospect.

Description

technical field [0001] The invention relates to a method in the technical field of composite materials, in particular to a bio-based porous carbon reinforced modified polyurethane composite material. Background technique [0002] Due to the adjustability of the ratio of soft and hard segments, polyurethane elastomers can prepare polyurethane materials with different properties and pathways, which are widely used in aerospace, marine ships, medical equipment, factory and mining machinery and other engineering fields. The soft segment of polyurethane elastomer determines the flexibility and toughness of the material, and the hard segment determines the strength and rigidity of the material. However, there is an obvious phase separation between the soft and hard segment. Therefore, the pure polyurethane material prepared by conventional methods and formulas has relatively low rigidity, thermal conductivity and thermal stability. Poor performance, low friction coefficient but hi...
