Abstract

The invention relates to the field of chemical materials, in particular to a chlorinated butyl rubber and silicone rubber blended material applied to a body material of a gas mask body. The chlorinated butyl rubber and silicone rubber blended material is prepared from, by weight, 50-100 parts of chlorinated butyl rubber, 5-50 parts of silicon rubber, 30-50 parts of intermediate super abrasion furnace black n220, 20-40 parts of high abrasion furnace black n330, 5-15 parts of zinc oxide, 1-10 parts of magnesium oxide, 0-10 parts of accelerator TT, 2-10 parts of accelerator ZDC, 1-10 parts of vulcanizer DCP, 2-8 parts of stearic acid, 2-12 parts of antioxidant methylene 4426 and 2-10 parts of anti-aging agents MB. The blended material has good gas defense performance, biocompatibility is improved due to the addition of silicon rubber, and the wearing comfort is improved on the premise that the protection performance is ensured.

Description

technical field [0001] The invention relates to the field of chemical materials, in particular to a blended material of chlorinated butyl rubber and silicone rubber applied to the main body material of a gas mask. Background technique [0002] Early gas masks mostly used natural rubber as the cover material. With the development of biotechnology and genetic engineering technology, higher requirements are put forward for the protective performance of gas masks. Therefore, the performance requirements for gas mask cover materials are also increasing. High, countries have adopted synthetic rubber with excellent comprehensive performance as the cover material. At present, the 65, 69, 87, 08, 09 and other generations of gas masks that have been developed in our country mainly use natural rubber in the early stage, which has the problem of poor anti-virus performance, while the butyl rubber used in the later stage is easy to deform and wear. Poor comfort, low assembly pass rate, ...
