Composite modified nano-hydroxyapatite-carbonized foaming phenolic resin based insulation material for forklift engine exhaust pipe and preparation method of insulation material

Abstract

The invention relates to an insulation material for an exhaust pipe, in particular to a composite modified nano-hydroxyapatite-carbonized foaming phenolic resin based insulation material for a forklift engine exhaust pipe and a preparation method of the insulation material. During preparation of the insulation material, foaming treatment is conducted on phenolic resin doped with mesocarbon microbeads at first; the obtained modified phenolic resin foam power is more efficient in carbonization in a follow-up carbonization process; the insulation material subjected to carbonization treatment is compact in structure, higher in strength and lower in thermal conductivity coefficient; the insulation material comprises a composite nano-hydroxyapatite adhesive doped with nano-titanium dioxide sol; the nano-hydroxyapatite adhesive can be utilized for not only bonding all raw materials well, but also effectively improving the strength of the insulation material and the high-temperature stability of pores, so that the insulation capability of the insulation material is kept efficient; the insulation material subjected to high-temperature treatment has the advantages of being lightweight, insulated, resistant to high-temperature oxidation, and environmentally friendly; insulation plates, insulation sleeves and other finished products made of the insulation material are excellent in insulation effect, efficient and durable; through the adoption of the insulation material, the working environment of a forklift engine is effectively improved.

Description

Technical field [0001] The invention relates to a heat insulation material for exhaust pipes, in particular to a composite modified nano hydroxyapatite-carbonized foamed phenolic resin based heat insulation material for forklift engine exhaust pipes and a preparation method thereof. Background technique [0002] During the continuous operation of the forklift, a large amount of heat will be generated in the exhaust pipe of the engine. Due to the circulation of heat, the temperature of the exhaust pipe will eventually be extremely high. If heat insulation is not performed, it will seriously affect the surrounding parts of the exhaust system. For normal work, the common treatment method is to wrap a heat shield made of materials with heat insulation effect on the outside of the exhaust pipe. The common heat insulation materials that make up the heat shield mainly include metal aluminum plates, asbestos cloth, glass fiber cloth, etc. However, these materials have some shortcomings. ...

Problems solved by technology

[0002] During the continuous operation of the forklift, the exhaust pipe of the engine will generate a lot of heat. Due to the circulation of heat, the temperature of the exhaust pipe will eventually be extremely high. If the heat insulation treatment is not carried out, it will seriously affect the parts around the exhaust system. The common treatment method is to wrap a heat shield made of materials with heat insulation effect outside the exhaust pipe. The common heat insulation materials that make up the heat shield mainly include metal aluminum plates, asbestos cloth, glass fiber cloth, etc. However, these materials have some disadvantages. For example, although aluminum materials have good heat insulation effects, their production costs are relatively high and their elongation is limited, while asbestos cloth and glass fiber cloth have short service life, are easily damaged, are not environmentally friendly, and need to be replaced frequently maintenance and other shortcomings, so it is urgent to develop a more efficient composite insulation material
