Problems solved by technology

[0002] Anti-vibration rings are required in some fields or in the use environment, such as air-conditioning motors, which need to achieve the dual functions of shock resistance and flame retardancy. Neoprene products have good physical and mechanical properties, oil resistance, and good weather resistance. Therefore, neoprene material will be used to prepare the shockproof ring. At the same time, in order to make it flame retardant and have basic strength requirements, flame retardants and carbon black will be added, but because the addition of traditional carbon black reinforcement systems and flame retardants is very difficult It is easy to increase the hardness of flame-retardant neoprene products, so the flame-retardant performance of low-hardness neoprene products has always been a difficult problem to solve

preparation example Construction

[0058] A preparation process of a low-hardness flame-retardant neoprene shockproof ring material, comprising the following steps:

[0059] Banburying: Add the raw neoprene rubber to the Banbury mixer for 2 minutes, then add carbon black, zinc oxide and stearic acid for banburying, the banburying time is 2 minutes, and the amount of carbon black added is carbon black. half of the total;

[0060] Then, the remaining carbon black is fully mixed with decabromodiphenylethane and antimony trioxide, and is added in three times, and each time is added to the mixer at an interval of 2 minutes. During the three additions, the operating oil is also added in three times. The last time Banbury for 4 minutes after the addition is completed; during the banburying process, the banburying temperature is 100-110°C;

[0061] Open mixing: Then put the mixed rubber after the internal mixing into the open mixing machine, and then add the vulcanizing agent and cross-linking accelerator into the mix...

Description

technical field [0001] The invention belongs to the technical field of material preparation, and particularly relates to a low-hardness flame-retardant neoprene shockproof ring material and a preparation process thereof. Background technique [0002] Anti-vibration rings are needed in some fields or environments, such as air-conditioning motors, etc., which need to achieve the dual functions of anti-vibration and flame retardant. Neoprene products have the advantages of good physical and mechanical properties, oil resistance, and weather resistance. Therefore, neoprene material will be used to prepare the shockproof ring. At the same time, in order to achieve the flame retardant effect and have basic strength requirements, flame retardants and carbon black will be added. However, because the traditional carbon black reinforcement system and the addition of flame retardants are very difficult It is easy to improve the hardness of flame-retardant neoprene products, so the flam...
