Composite modified light-burned magnesium oxide-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 light-burned magnesium oxide-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 light-burned magnesium oxide composite adhesive with aluminum hydroxide sol has favorable bonding capacity and formability, and effectively enhances the strength and heat insulating capacity of the material; the material prepared by performing high temperature carbonization on the composite blank has the advantages of excellent heat insulating property, excellent wear resistance, excellent shock and sound absorption properties 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.
