Abstract

The invention relates to a cryogenic rubber thermal insulation material and a preparation method thereof. The thermal insulation material is prepared from the following components in parts by weight:15-25 parts of EPDM (ethylene propylene diene monomer), 5-10 parts of IIR (isobutylene isoprene rubber), 5-10 parts of BR (butadiene rubber), 10-15 parts of a high-temperature foamer (AC), 5-8 parts of Sb2O3, 0.5-1 part of zinc oxide, 0.2-0.4 parts of sulfur, 10-15 parts of DOP (diocty phthalate), 0.2-0.4 parts of zinc diethyldithiocarbamate (E), 0.1-0.4 parts of an anti-aging agent (4020), 1.2-2parts of an antioxidant (AST-500). Flexibility and elasticity are improved by substituting a traditional rubber-plastic foam product for a full rubber foam product; meanwhile, with adoption of the preparation method, the product can be resistant to ultraviolet rays, and aging resistance is enhanced. Besides, an added microballoon foamer is adopted for changing the foam structure to lock the air, and the material is more energy-saving and thermal-insulating. The material can keep soft, bent and elastic at low temperature, and is the thermal-insulating, non-corrosive and environment-friendly product.

Description

technical field [0001] The invention relates to the application field of thermal insulation materials, in particular to a cryogenic rubber thermal insulation material and a preparation method thereof. Background technique [0002] The thermal insulation materials on the market today generally use closed-cell materials, such as polyurethane, foam glass, polyisocyanurate, rubber and plastic insulation materials, etc. In the field of ultra-low temperature, due to the problems of condensed water and low temperature, these traditional thermal insulation materials are Hard materials will cause many problems during use, such as the treatment of the joints of hard materials, the process of thermal expansion and contraction of pipelines, or impacts that may cause material fragmentation and failure, material cutting, and inconvenient construction. . Cryogenic rubber thermal insulation material, its main feature is flexible material, easy to construct, and can still maintain a certain...
