Composite modified sepiolite fabric-carbonized foamed phenolic resin based heat insulating material for exhaust pipe of fork truck engine and preparation method of composite modified sepiolite fabric-carbonized foamed phenolic resin based heat insulating material
The invention relates to a heat insulating material for an exhaust pipe, and in particular relates to a composite modified sepiolite fabric-carbonized foamed phenolic resin based heat insulating material for the exhaust pipe of a fork truck engine and a preparation method of the composite modified sepiolite fabric-carbonized foamed phenolic resin based heat insulating material. During the preparation of the material, the phenolic resin mixed with intermediate phase carbon microspheres is subjected to foaming treatment at first, so that the prepared modified phenolic resin foam powder is more efficient during subsequent carbonization, a carbonized material is compact in structure, higher in strength and lower in thermal conductivity, and a composite sepiolite fabric adhesive not only has good bonding capacity but also ensures that the carbonized material is low in heat shrinkage rate, is corrosion-resistant, has high strength and toughness and has the advantages of light weight, heat insulation, environment-friendliness and the like; and the finished products of a heat insulating plate, a heat insulating sleeve and the like prepared from the material are predominant in heat insulation effect and are efficient and durable, and the working environment of the fork truck engine is effectively improved.
