Problems solved by technology

Cots made of nitrile rubber are resistant to oil but not acid and alkali. Cots made of chloroprene rubber are resistant to acid and alkali but poor in oil resistance. Cots made of polyamine rubber are wear-resistant but easy to soften when exposed to water. The rubber roller made of rubber is resistant to oil but resistant to acid and alkali but has poor mechanical properties
The use of different mixing rubber roller materials makes different rubber rollers have different scrapping periods, and the service life of various rubber rollers is short (long four or five months, short two or three months), during the production process It is necessary to change different rubber rollers from time to time and change frequently, which seriously affects the production efficiency
In addition, due to the large variety and quantity of rubber rollers, it takes up a large warehouse volume, which makes the records of the custodians unclear and easily leads to confusion in production.

Embodiment 1

[0026] In the first step, take 50 kg of chlorinated polyethylene rubber CM, 45 kg of nitrile rubber / polyvinyl chloride (70 / 30) alloy, 10 kg of oligomer fat TP-955 kg and zinc methacrylate into the rubber seal. In the mixing machine, keep the temperature at 150°C for rubber mixing for 10 minutes, then put 5 kg of magnesium methacrylate and 1 kg of stearic acid into the internal mixer for rubber mixing for 8 minutes, and then add 20 kg of N220 Carbon black, 18 kg of N330 carbon black, 22 kg of 1250-mesh ultrafine talcum powder, 15 kg of filler composed of micron-sized magnesium oxide, and 15 kg of plasticizer DOP were placed in the internal mixer in turn for 10 minutes after rubber mixing Stop the machine and turn over the warehouse to discharge the material, cool to below 65°C for use;

[0027] The second step is to add the rubber sheet made by rubber mixing into the rubber mill at a temperature of 55°C, and then add 0.5 kg of accelerator DM, 0.5 kg of accelerator CZ, and 1.5 k...

Embodiment 2

[0029] In the first step, 60 kg of chlorinated polyethylene rubber, 55 kg of nitrile rubber / polyvinyl chloride (70 / 30) alloy, 15 kg of oligomeric fat TP-85 and 8 kg of zinc methacrylate are inserted into the rubber In the internal mixer, keep the temperature at 160°C for rubber mixing for 8 minutes, then put 6 kg of magnesium methacrylate and 0.5 kg of stearic acid into the internal mixer for 4 minutes, and then mix 15 kg of N220 carbon black, 18 kg of N330 carbon black, 20 kg of 1250-mesh ultrafine talcum powder, 20 kg of filler made of quartz, and 20 kg of plasticizer DOP were placed in the internal mixer in sequence for 6 minutes and then stopped and turned over. Out of the warehouse, cool to below 40°C for use;

[0030] In the second step, add the rubber sheet formed by rubber mixing into the rubber mill at a temperature of 45°C, and then add 0.75 kg of accelerator D and 0.5 kg of accelerator M, 1.0 kg of sulfur chloride and 1.5 kg of After the cyanuric acid resin is pack...

Embodiment 3

[0032] In the first step, 55 kg of chlorinated polyethylene rubber, 50 kg of nitrile rubber / polyvinyl chloride (70 / 30) alloy, 20 kg of oligomeric fat TP-92 and 6 kg of zinc methacrylate are inserted into the rubber In the internal mixer, keep the temperature at 180°C for rubber mixing for 15 minutes, then put 8 kg of magnesium methacrylate and 1.5 kg of stearic acid into the internal mixer for 6 minutes, and then put 20 kg of N220 carbon black, 30 kg of N330 carbon black, 20 kg of 1250-mesh ultrafine talcum powder, 15 kg of micron-sized magnesium oxide, 20 kg of quartz filler, and 25 kg of plasticizer DOP are put into the internal mixer in sequence After 8 minutes of middle rubber mixing, stop the machine and turn over the warehouse to discharge the material, and cool to below 45°C for use;

[0033] In the second step, add the rubber sheets formed by rubber mixing into the rubber mill at a temperature of 50°C, and then add 0.5 kg of accelerator DM, 0.75 kg of accelerator CZ, 1...

Abstract

An oil-resisting and anti-acid mixed material and its production are disclosed. The mixed material consists of chlorinated polyethylene rubber, butadieneacrylonitrile latex / polyvinyl chloride (70 / 30) alloy, oligomer ester, metacrylic acid zinc, metacrylic acid magnesium, filler, improver, vulcanizing agent and plasticizerDOP. The process is carried out by milling and membrane penetrating. It has long life and can be used for rubber-covered roller, hose, lining material of chemical corrosive-proof container.

Description

technical field [0001] The invention belongs to the technical field of rubber products, and in particular relates to a wear-resistant, oil-resistant, acid- and alkali-resistant mixing material. Background technique [0002] In the production line of stainless steel plates, in order to adapt to different production environments, the rubber rollers set up are composed of nitrile rubber, neoprene rubber, polyamine rubber and butyl rubber. Cots made of nitrile rubber are resistant to oil but not acid and alkali. Cots made of chloroprene rubber are resistant to acid and alkali but poor in oil resistance. Cots made of polyamine rubber are wear-resistant but easy to soften when exposed to water. The rubber roller made of rubber is resistant to oil but acid and alkali but has poor mechanical properties. The use of different mixing rubber roller materials makes different rubber rollers have different scrapping periods, and the service life of various rubber...
