The oil added during the processing of rubber products is rubber oil. For rubber oil, rubber manufacturers expect that they have good compatibility with rubber, low volatility, good processing performance, good stability, low pollution, low price, etc. Characteristics, but there are many types of rubber oil, which can be divided in paraffin-based olefin wax-based rubber oils, naphthenic rubber oils, and aromatic rubber oils according to their molecular structure and composition. Different types of rubber oils have different properties in rubber products. The scope of use is different, what kind of rubber oil is best?
1. Paraffin-based rubber oil: This type of rubber oil has better ozone resistance and light stability than naphthenic rubber oil and aromatic rubber oil, which can improve the elasticity and processing performance of rubber products, and the tensile strength of vulcanizates. The tensile stress and hardness are good, and the heat generation during the processing is low; the emulsification, compatibility, and low temperature performance are relatively poor, and the rubber products added with the paraffin-based rubber oil have a relatively slow curing speed.
2. Cycloalkyl rubber oil: Cycloalkyl rubber oil is a rubber oil between the properties of paraffin-base rubber oil and aromatic rubber oil. It is mostly used as a replaceable to aromatic rubber oil. It is environmentally friendly and non-toxic. , tasteless, non-polluting, good emulsifying performance and compatibility, good processing performance, basically will not affect the vulcanization rate of rubber products; rubber products added with naphthenic rubber oil, elasticity, tensile strength, tensile stress Such as comprehensive performance is good, heat is medium, in the rubber product industry application field is more and more wide.
3. Aromatic rubber oil: Aromatic rubber oil has the best compatibility with rubber, and can significantly increase the ductility and tensile strength of rubber; rubber vulcanizates using aromatic rubber oil have low temperature performance and excellent processing performance. , The rubber material has higher resilience, higher target values such as constant stress and hardness, and vulcanization speed, but the heat production is high during the production of rubber products. Aromatic rubber oils are low in price, but they have a darker color and are more polluting. Therefore, the EU gradually restricts the use of non-environmentally friendly aromatic oils, mainly because of the carcinogenicity of non-environmentally friendly aromatic oils.
The above three types of rubber oil have their own characteristics, rubber products manufacturers still have to choose the right rubber oil products according to the performance requirements of their own rubber products, rubber processing plant processing equipment and conditions, relevant rubber product inspection and other qualified standards , Strive to improve the rubber processing performance, the ideal performance without affecting the other properties of rubber products.
Hongyun Environmental Protection Tasteless Tal Oil is currently the most environmentally friendly industrial vegetable oil. Compared with other rubber oils, it emulsifies quickly, easily dispersed, does not migrate, and resists air bubbles. It can be used in various export-oriented rubber products and environmental protection type. In the production of rubber products.
