High temperature resistant overall hydrophobic insulation material and preparation method thereof
The present invention discloses a high temperature resistant overally hydrophobic insulation material and a preparation method thereof. The material overcomes the disadvantage of hydrophilicity of the existing insulation materials, has good hydrophobic effect, can be used normally at 450 DEG C and still maintain good hydrophobic properties, so that the insulation material has huge economic and social benefits. An optimum formula is selected before preparation; gelation is conducted according to the optimum formula, and then a hydrophobic agent by means of a carrier is incorporated into the insulation material, so as to achieve internal hydrophobization; then pressing, autoclaving and drying are carried out to obtain the insulation material; and a coating liquid is applied on the surface of the insulation material; after curing UV and coating liquid curing, a hydrophobic film is attached to the surface of the insulation material, thereby obtaining the high temperature overall hydrophobic insulation material. The process comprises the specific steps of: 1, material preparation; 2, gelation; 3, compacting and moulding; 4, steam autoclaving treatment; 5, posttreatment; 6, sol; and 7, film coating.
