Refractory coating material comprising refractory rubber composition, from the refractory rubber composition, refractory coating process and a method of using a refractory coating material

摘要

The present invention provides a fire-resistant rubber composition, forming body can keep enough shape stability even exposed in very hot condition, also excellent operation efficiency can be applied to fire-resistant material formed from the fire-resistant composition. The present invention provides an unvulcanized fire-resistant rubber composition, in 100 mass ratio of base rubber components composed of 30 to 50 mass ratio of liquid rubber, 50 to 70 mass ratio of butyl rubber, 10 to 60 mass ratio of bonding agent, 10 to 100 mass ratio of heat expansion graphite, 50 to 170 mass ratio of aluminum phosphorous acid, 50 to 170 mass ratio of inorganic filler, 0.1 to 10 mass ratio of vulcanizing agent and 0.1 to 10 mass ratio of vulcanizing accelerator are contained for mixing at 60 to 100 Degrees. In addition, fire-resistant cover material shaped by the fire-resistant rubber composition and fire-resistant cover process method using the same are provided.
