Abstract

The invention relates to a CPE/CPVC rubber-plastic thermal-insulation material and a preparation method thereof and belongs to the field of polymer synthesis and processing application. The CPE/CPVC rubber-plastic thermal-insulation material is prepared from 100 parts by mass of CPE/CPVC resin, 1.5-10 parts by mass of a stabilizing agent, 0.3-3 parts by mass of a composite lubricant, 10-50 parts by mass of a plasticizer, 0.3-5 parts by mass of a foaming agent, 0.4-1.0 part by mass of a foaming aid, 1-4 parts by mass of a foaming adjustment agent, 0-15 parts by mass of a fire retardant and 0-20 parts by mass of a filling material. The CPE/CPVC rubber-plastic thermal-insulation material has excellent performances such as softness, flexing damage resistance, cold resistance, heat resistance, flame retardation, water resistance, low heat-conduction coefficient, cushioning effect and sound absorption and has ideal use effects in the aspect of thermal insulation for heat loss prevention. The preparation method of the CPE/CPVC rubber-plastic thermal-insulation material is simple and continuous, has high production efficiency, is suitable for streamline batch production and can be widely used in industries of building, light textile, medicine, chemical engineering, metallurgy and ship-building.

Description

technical field [0001] The invention relates to a CPE / CPVC rubber-plastic insulation material and a preparation method thereof, belonging to the field of synthesis and processing of polymer materials. Background technique [0002] Commonly used insulation materials include asbestos, centrifugal glass wool, flame-retardant polyethylene foam, rigid polyurethane foam, rubber-plastic sponge, etc., among which rubber-plastic sponge is more common. Rubber and plastic sponge is a kind of rubber and plastic foam insulation material synthesized by nitrile rubber, PVC resin, a large amount of flame retardant, plasticizer, foaming agent, vulcanizing agent, filler and other additives. [0003] Chinese patent CN1100091C introduces a rubber-plastic sponge prepared by processes such as weighing preparation, preliminary training, mixing, extrusion, foaming, cutting and packaging, with nitrile rubber and PVC resin as main materials and various additives as auxiliary materials. Flame retarda...
