Abstract

The invention discloses an AE multi-element aerogel rubber blended closed-pore secondary mold pressing foaming material. The material is prepared from the following components in parts by weight: 100parts of food-grade PVC, 20-30 parts of NBR, 40-50 parts of a processing aid, 10-15 parts of a heat-insulating aid, 3-5 parts of a structure stabilizer, 1-2 parts of a heat stabilizer, 1-2 parts of anactive agent, 0.5-1 part of a cross-linking agent, 10-15 parts of a foaming agent and 0.03-0.05 part of a color stabilizer. A proper formula and a proper process are combined, the formula componentsare creatively selected, the production technology breakthrough of high-dispersity, high-foaming-ratio, low-density, heat-preservation and heat-insulation products is effectively achieved, the densityis 70 + / -20 kg / m<3>, the heat conductivity coefficient is smaller than or equal to 0.020 W / m.k, and the material is small in heat conductivity and good in heat insulation performance.

Description

technical field [0001] The invention relates to the field of polymer materials and their preparation, in particular to AE multi-component airgel rubber-plastic blended closed-cell secondary molding foaming materials and a preparation method thereof. Background technique [0002] NBR and PVC are rubber blended mixed foam materials, among which NBR is the abbreviation of nitrile rubber, PVC is the abbreviation of polyvinyl chloride, and the blended rubber made of NBR and PVC is the main rubber used in combination with rubber and plastic at present. . The main advantages are heat preservation, good tensile strength, oil resistance, heat resistance and so on. [0003] In the prior art, when preparing NBR and PVC rubber blended mixed foam materials, processing aids are often added to increase fluidity. For example, application number CN201310395682.6 discloses light-colored NBR / PVC with high acrylonitrile content The preparation method of oil-resistant rubber material is mechan...
