Abstract

The invention discloses an environment-friendly oil-resistant and flame-retardant rubber board and a preparation method thereof. The environment-friendly oil-resistant and flame-retardant rubber board comprises the following raw materials in parts by mass: 70 parts of chloroprene rubber, 30 parts of nitrile rubber, 4 to 6 parts of zinc oxide, 3 to 5 parts of magnesium oxide, 1 to 2 parts of stearic acid, 0.3 to 0.5 part of accelerant, 0.3 to 0.8 part of vulcanizing agent, 120 to 150 parts of aluminium hydroxide and 1 to 5 parts of coloring agent. The environment-friendly oil-resistant and flame-retardant rubber board has the advantages that the hardness, tensile strength and tear strength properties are excellent, the content of heavy metal and harmful organic matters is obviously reduced, no cancerogen ingredient is contained, the flame-retardant and oil-resistant properties are obviously improved, and the environment-friendly and high flame-retardant requirements are completely met.

Description

technical field [0001] The invention relates to an environment-friendly, oil-resistant and flame-retardant rubber sheet and a preparation method thereof, belonging to the field of rubber sheets. Background technique [0002] Rubber is an elastic polymer. According to the different ways of making it, rubber can be divided into two categories: synthetic rubber and natural rubber. Since the rubber main chain has a large amount of carbon, hydrogen, oxygen and other elements, it is easy to produce combustible gas when heated and melted, and it is easy to burn with oxygen at high temperature. In order to achieve the purpose of flame retardancy, the traditional method is to use halogen-containing polymers and add a large amount of halogen-containing flame retardants. However, once a fire breaks out, it will produce a large amount of smog and toxic corrosive hydrogen halide gas, causing secondary disasters, and its harm is often more serious than the direct consequences of burning;...
