▎ 摘　　要

NOVELTY - Long-term oxygen blocking floor heating pipe with far-infrared radiation function comprises oxygen barrier layer with far-infrared radiation performance, bonding layer and polyolefin resin layer. The thickness ratio of oxygen barrier layer, bonding layer and polyolefin resin layer is 1.5:0.5:8. The specific composition and mass fraction of oxygen barrier layer comprises 100 pt. wt. ethylene vinyl alcohol (EVOH) resin and 1-8 pts. wt. modifier. The modifier comprises graphene, seaweed carbon, ceramic powder and silica at mass fraction ratio of 1-2:2-5:2-5:1-3. The bonding layer is made of maleic anhydride grafted polyethylene. The polyolefin resin layer is made of heat-resistant polyethylene. USE - Long-term oxygen blocking floor heating pipe with far-infrared radiation function. DESCRIPTION OF DRAWING(S) - The drawing shows the present invention with far infrared radiation function long-acting oxygen-resistant floor heating pipeline section structure schematic diagram. Polyolefin resin layer (1) Bonding layer (2) Oxygen-resistant layer (3)
