Embodiment 1

[0017] High temperature resistant, flame retardant, oil resistant rubber compound, the formula is: nitrile rubber: 100phr; dimorpholine disulfide: 2phr; zinc oxide: 5phr; stearic acid: 2phr; N-cyclohexyl-2-benzothiazole Sulphenamide: 1phr; Zinc diethyldithiocarbamate: 3phr; Carbon black: 30phr; Dioctyl phthalate: 15phr; 2,2,4-Trimethyl-1,2-dihydroquinoline Phenyl polymer: 3phr; Magnesium hydroxide: 70phr;

[0018] A method for producing high-temperature-resistant, flame-retardant, and oil-resistant rubber compound, the method is as follows:

[0019] The first step: use nitrile rubber and magnesium hydroxide to make masterbatch;

[0020] Step 2: Add zinc oxide, stearic acid, N-cyclohexyl-2-benzothiazole sulfenamide, carbon black, dioctyl phthalate, 2,2,4- Trimethyl-1,2-dihydroquinoline polymer is mixed to obtain a rubber compound;

[0021] The third step: adding dimorpholine disulfide and zinc diethyldithiocarbamate separately to the above mixed rubber to obtain the high tem...

Embodiment 2

[0023] High temperature resistant, flame retardant, oil resistant rubber compound, the formula is: nitrile rubber: 100phr; dimorpholine disulfide: 3phr; zinc oxide: 7phr; stearic acid: 3phr; N-cyclohexyl-2-benzothiazole Sulfenamide: 2phr; Zinc diethyldithiocarbamate: 4phr; Carbon black: 40phr; Dioctyl phthalate: 25phr; 2,2,4-Trimethyl-1,2-dihydroquinone Phenyl polymer: 6phr; Magnesium hydroxide: 100phr;

[0024] Production method is the same as embodiment one.

Abstract

The invention discloses rubber compound which is high temperature resistant, fire-proof and grease-proof and a production process, which is formed by raw materials with following weight: 100phr acrylonitrile butadiene, 2-3phr vulcanizing agent, 5-7phr zinc oxide, 2-3phr octadecanoic acid, 1-2phr medium accelerator, 3-4phr ultra fast accelerator, 30-40phr carbon black, 15-25phr softening agent 3-6phr anti-aging agent and 70-100phr halogen-free flame retardant. High temperature resistant and fire-proof sizing material which is produced through the sizing material formulation and the process realizes the high temperature resistance and fire-proof properties of acrylonitrile butadiene at the premise of non halogen-free environmental protection, is used to shoemaking production, and is suitable for work footwear under the condition of high temperature and temporary open flame.

Description

technical field [0001] The invention relates to a high-temperature-resistant, flame-retardant, oil-resistant rubber compound that can be used for special labor protection such as fire-fighting shoes and boots and a production method thereof. Background technique [0002] In the field of special labor insurance footwear production, there is no precedent for using general or semi-general rubber to produce rubber soles with high temperature resistance, flame retardancy and oil resistance. Similar to the performance of soles, the index value does not meet the specified performance, and it has the environmental protection performance of halogen-free flame retardant. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rubber compound that uses nitrile rubber to achieve high temperature resistance and flame retardancy and its production method. [0004] The technical solution adopted by the present invention to solve the...
