Embodiment 1

[0028] A rubber sheet containing a flame-retardant component and a preparation method thereof, the rubber material components and components by weight of the flame-retardant component include: 30-60 parts of fluororubber, 30-45 parts of silicone rubber, and 2-4 parts of sulfur , 3-5 parts of vulcanization accelerator, 5-9 parts of stearic acid, 1-5 parts of anti-aging agent, 3-5 parts of paraffin, 20-30 parts of flame retardant, 2-10 parts of calcium carbonate, 15-20 parts of reinforcing agent 1-5 parts of aromatic hydrocarbons, 4-12 parts of clay, 15 parts of white carbon black, 3 parts of anti-scorch agent; 10-20 parts of wollastonite. The flame retardant is one of chlorine-based flame retardants, bromine-based flame retardants, phosphorus-based flame retardants and inorganic flame retardants. Since fluororubber and silicone rubber have good heat resistance, the heat resistance of the rubber sheet can be better increased through the mutual cooperation of flame retardants. T...

Abstract

The invention discloses a rubber plate containing a flame-retardant component and a preparation method of the rubber plate. The rubber material with the flame-retardant component comprises the following components in parts by weight: 30-60 parts of fluororubber, 30-45 parts of silicone rubber, 2-4 parts of sulfur, 3-5 parts of a vulcanization accelerator, 5-9 parts of stearic acid, 1-5 parts of an anti-aging agent, 3-5 parts of paraffin, 20-30 parts of a flame retardant, 2-10 parts of calcium carbonate, 15-20 parts of a reinforcing agent, 1-5 parts of aromatic hydrocarbon, 4-12 parts of argil, 15 parts of white carbon black, 3 parts of a scorch retarder, and 10-20 parts of grammite. The invention relates to the technical field of the rubber plate containing a flame-retardant component and the preparation method of the rubber plate. According to the rubber plate containing the flame-retardant component and the preparation method of the rubber plate, the problem that an existing rubber plate containing the flame-retardant component does not have good toughness and ageing resistance is solved.

Description

technical field [0001] The invention relates to the technical field of a flame-retardant rubber sheet and a preparation method thereof, in particular to a rubber sheet containing a flame-retardant ingredient and a preparation method thereof. Background technique [0002] Flame retardant rubber refers to rubber with flame retardancy and flame retardancy. Rubber is an organic flammable material, which is harmful to safety. Therefore, rubber conveyor belts for mines and various rubber products for vehicles and ships are required to have flame retardancy and flame retardancy. Flame retardant rubbers include: neoprene, chlorosulfonated polyethylene, polyvinyl chloride and silicone rubber. Combining flame-retardant polymers with flammable rubber can improve flame retardancy, such as polyvinyl chloride and nitrile rubber. Increasing the crosslink density of the vulcanizate can also improve the flame resistance. Adding flame retardants is a way to improve the flame retardancy of ...
