Composite modified colloidal graphite-carbonized foam phenolic resin base insulation material for forklift truck engine exhaust pipe and preparation method of composite modified colloidal graphite-carbonized foam phenolic resin base insulation material
The invention relates to a heat insulation material for an exhaust pipe, in particular to a composite modified colloidal graphite-carbonized foam phenolic resin base insulation material for a forklift truck engine exhaust pipe and a preparation method of the composite modified colloidal graphite-carbonized foam phenolic resin base insulation material. Phenolic resin doped with mesocarbon microbeads is firstly foamed in the preparation process, so that the prepared modified phenolic resin foam powder is relatively efficient in the subsequent carbonization process; the carbonization material is compact in structure, relatively high in strength, and relatively low in heat conductivity coefficient; a composite colloidal graphite powder adhesive containing silica sol has good adhesive ability and casting ability; the carbonization effect is also improved; the material porosity is improved; the material subjected to high-temperature treatment has the advantages of high strength and tenacity, light weight, thermal insulation and noise reduction; the products such as a heat insulation plate and a heat insulation sleeve prepared from the material are excellent in heat insulation effect, high in efficiency and durable; and the work environment of a forklift truck engine is effectively improved.
