At present, some companies use ordinary paraffin wax instead of rubber protective wax in order to reduce costs and pursue profits. From the immediate point of view, they can get certain benefits, but in the long run, the gains outweigh the losses.
Because ordinary paraffin is used in addition to the poor adaptability mentioned above, the most important thing is that the internal quality of ordinary paraffin is unstable due to the different components of crude oil used by various oil refining companies, and the carbon number distribution and its content are incomplete.
Therefore, when ordinary paraffin is used as a protective wax, phenomena such as spraying, whitening, and rainbows often appear on the surface of the rubber.
The surface of the rubber compound is rough and dull, which seriously affects the appearance of rubber products, makes the product lack the ability to prevent aging, affects the user's recognition of the product, and ultimately affects the sales of the product.
Therefore, it is recommended not to use ordinary paraffin wax as rubber protective wax, especially for tire sidewall compounds and rubber products under high temperature conditions. The rubber protective wax suitable for the use of rubber materials should be correctly selected to improve product quality, create a famous brand, and increase benefits.
Reasonable selection of rubber protective wax is an important link that cannot be ignored when preparing rubber products. The correctness, practicability and economy of selection must be considered when selecting. The following points must be noted.
1. The grade of rubber products
2. The use temperature range of rubber products
3. Working conditions of rubber products
4. The service life of rubber products, etc.
The rational selection of rubber protective wax required for rubber products focuses on the internal composition structure of the protective wax selected, that is, its carbon number distribution structure.
When using, we must pay attention to the reasonable preparation of a certain amount of rubber protective wax to ensure that a sufficient amount of rubber protective wax migrates to the surface layer in the whole process of use of rubber products, so as to achieve the effect of anti-aging in the whole process.
At present, the preparation of protective wax for rubber products in China is generally 1-4 parts of the total amount of rubber. Here, users are reminded that they must pay attention to the quality of rubber softener when choosing all-weather rubber protective wax.
If the wax content in the rubber softener is too high (the reference data sp is too high), and the front peak light component wax of the all-weather rubber protective wax is combined, it will often spray together, so be careful when choosing.
