Problems solved by technology

Moreover, because silica airgel has the properties of sound insulation and heat preservation, ethylene-propylene rubber is mostly used in conjunction with silica airgel to prepare rubber products with sound insulation and heat preservation; but in the process of preparing rubber products, silica gas condensation The poor mechanical properties of the rubber and the poor dispersibility of the filler calcium carbonate in the reaction system lead to the disadvantages of poor mechanical properties, vulcanization properties, and aging resistance of rubber products, thus becoming the focus of the present invention's research

Abstract

The invention relates to the field of rubber, and particularly discloses a sound-insulation heat-preservation rubber product and a preparation method thereof. The formula comprises at least the following components: an ethylene-propylene-diene monomer, silicon dioxide aerogel, a filler, sulfur, an activator, a plasticizer, an anti-aging agent, an organic foaming agent and paraffin oil. According to the rubber product and method provided by the invention, the modified silicon dioxide aerogel is used, so that mechanical properties of silicon dioxide aerogel are improved, and mechanical properties and vulcanization properties of a rubber compound are further improved by controlling a usage amount ratio of the silicon dioxide aerogel; in addition, filler light weight calcium carbonate is modified, so that dispersibility of light weight calcium carbonate is improved, the vulcanization properties of the rubber compound are improved; and the modified silicon dioxide aerogel and the modified light weight calcium carbonate are comprehensively coordinated, so that the prepared rubber product has more excellent tensile strength, elongation at break and vulcanization properties.

Description

technical field [0001] The invention relates to the field of rubber, in particular to a sound-insulating and heat-insulating rubber product and a preparation method thereof. Background technique [0002] Ethylene-propylene rubber is a synthetic rubber formed by copolymerization of ethylene and propylene-based monomers, and its use and consumption are still expanding. According to the composition of monomer units in the rubber molecular chain, it can be divided into binary ethylene-propylene rubber and tertiary ethylene-propylene rubber. The former is a copolymer of ethylene and propylene; the latter is the third unit of ethylene, propylene and a small amount of non-conjugated dienes. Body copolymers, collectively referred to as ethylene-propylene rubber. Ethylene-propylene rubber is mainly used in the automobile industry, wire and cable industry, construction industry, etc., as well as civilian rubber products, waterproof materials and other rubber-plastic materials, such a...
