D. b. and c. master batch, adsorbent, emulsifier and the color masterbatch obtained flat squeeze into of mixing → use is carried out to blow in batch mixer Mixed mixing is added in extruder hopper, by spiro rod plasticizing, is squeezed out by machine head port mould thin by method thin film preparation process Film, inflation, it is air-cooled after, by traction roller, then by being batched after several rollers, obtain the thin layer with a thickness of 300~500 μm；
E. Wear-resistant skid-proof coating is coated on thin layer outer surface, the wear-resisting antiskid performance on its surface is improved, on film embossing machine It is embossed processing, pressure are as follows: 80~100MPa；
Thus to obtain two material of surface layer；
(5) the acquisition of three-decker multi-function thermal-insulation material:
A. the Double layer thermal insulation material previously obtained is subjected to cleaning treatment, then the surface layer one after embossing is spread into cloth in transition zone Top for plate material or outside for thimble tube material, obtain final multi-layer multi heat preserving and insulating material, Miscellaneous function is the anti-aging property of material, and material type can be tubing casing or plate, i.e., anti-aging type insulation material Material；
B. the Double layer thermal insulation material previously obtained is subjected to cleaning treatment, then the surface layer two after embossing is spread into cloth in transition zone Top for plate material or outside for thimble tube material, obtain final multi-layer multi heat preserving and insulating material, Miscellaneous function is the wear-resisting antiskid performance of material, and material type can be tubing casing or plate plate, referred to as wear-resistant anti-skidding Heat preserving and insulating material.
