The continuous pore rubber-plastic slow-rebound foaming material comprises a main material, resin, a filler, a plasticizer, a lubricant, sulfur, a vulcanizing agent, a vulcanization active agent, an accelerator and a foaming agent; the main material is 50 parts to 70 parts of nitrile rubber; the resin is 30 parts to 50 parts of PVC resin; the filler comprises 0 to 30 parts of carbon black, 40 parts to 80 parts of powdered steatile and 60 parts to 70 parts of active aluminum hydroxide; the plasticizer comprises 10 parts to 30 parts of dioctyl phthalate and 10 parts to 50 parts of chlorinated paraffin; the lubricant comprises 1 part to 2 parts of stearic acid, 1 part to 2 parts of paraffin, 1 part to 2 parts of polyethylene glycol, and 1.5 parts to 2.5 parts of sulfur; the accelerator includes 1 to 3 parts of mercaptobenzothiazole, 0 to 1.5 parts of dipentylene thiuram tetrasulfide, 0.2 parts to 1.5 parts of zinc diethyldithiocarbamate and zinc dibutyl dithiocaarbamate; the vulcanization active agent includes 1 part to 3 parts of stearic acid and 1 part to 10 parts of zinc oxide; and the foaming agent includes 5 part to 25 parts of stearic acid and 1 parts to 10 parts of low-temperature complex foaming agent ACP-J. The steps and the finished product have characteristics of high quality, good process quality control, high production efficiency, and low energy consumption.

Description

technical field [0001] The invention relates to a foam material, in particular to a continuous-pore rubber-plastic slow-rebound foam material and a preparation method thereof, belonging to the technical field of rubber foam material processing. Background technique [0002] Polymer foamed material refers to a microporous material based on polymer (plastic, rubber, elastomer or natural polymer material) with numerous bubbles inside. It can also be regarded as a composite material filled with gas. Polymer There are many types of foam materials. Typical foaming materials such as polyurethane (PU) foam, polystyrene (PS) foam. Polyolefin foam, polyvinyl chloride (PVC) foam, phenolic foam, epoxy resin foam and other thermoplastic and thermosetting foam plastics, nitrile rubber foam, thermoplastic elastomer foam and foaming starch, foaming plant fiber and other natural polymer hair bubble material. In the preparation process, higher index and density will lead to higher closed c...
