NOVELTY - A low thermal conductivity sound insulation material comprises 30-45 pts. wt. rubber base material, 2-10 pts. wt. high molecular polymer, 5-12 pts. wt. foaming agent, 30-45 pts. wt. smoke suppressant, 0.5-1.5 pt. wt. stearic acid, 20-30 pts. wt. plasticizer, 5-15 pts. wt. solid filler, 1-3 pts. wt. antioxidant, 2-6 pts. wt. accelerator, and 10-15 pts. wt. additive. USE - Low thermal conductivity sound insulation material for buildings e.g. houses and offices. ADVANTAGE - The sound insulation material has excellent mechanical property, low thermal conductivity coefficient, excellent thermal insulation performance and high quality, and effectively reduces the material moisture absorption phenomenon, and is economical and environmentally friendly durable material, and has excellent thermal insulation and sound insulation effect in the construction of houses and offices. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the low thermal conductivity sound insulation material, which involves weighing other raw materials except the accelerator, adding all raw materials to banbury mixer, banburying, discharging to obtain initial material, adding to open mill for slicing to obtain initial material film, adding the initial material film to the open mill again, adding accelerator after pressing through heat roller, subjecting to continuous feeding reaction to obtain the initial material rubber strip, extruding through multi-screw extruder to obtain molding material, spraying and calendering of carbon material and aerogel on the surface, heating through multi-section drying tunnel, foaming to obtain a rubber-plastic tube, cooling and cutting.
