[0033] Example
[0034] The intumescent flame-retardant rubber of the present invention is exemplified by taking the mass of the matrix resin as 100 parts, and the remaining components are calculated relative to the content of 100 parts of resin (phr, the number of parts of filler added per 100 parts of resin). Intumescent flame retardant rubber formula component content and technical performance indicators are shown in Table 2.
