Composite modified diatomite-carbonized foamed phenolic resin-base heat insulating material for fork truck engine exhaust pipes and preparation method thereof
The invention relates to a heat insulating material for exhaust pipes, particularly a composite modified diatomite-carbonized foamed phenolic resin-base heat insulating material for fork truck engine exhaust pipes and a preparation method thereof. In the preparation process, a phenolic resin blended with an intermediate phase charcoal microsphere is firstly foamed, so that the obtained modified phenolic resin foam powder has higher efficiency in the subsequent carbonizing process, and the carbonized material has the advantages of compact structure, higher strength and lower heat conductivity coefficient; the composite diatomite adhesive has favorable bonding capacity and well bonds the raw materials; the blank subjected to high-temperature sintering has a uniform and compact microporous structure, and has the advantages of light weight, high strength, favorable heat insulating property, high temperature resistance, environment friendliness and the like; and the heat insulating plate, heat insulating sleeve and other finished products prepared from the material have the advantages of excellent heat insulating effect, high efficiency and high durability, and effectively improve the working environment of the fork truck engine.
