The tire reclaimed rubber is black block solid, which replaces some of the natural rubber, styrene-butadiene rubber and other general rubber to produce black or dark rubber products, which can reduce the cost of raw materials and improve the multiple functions of the processing technology. Some rubber sheets and rubber miscellaneous pieces can even be used. The tire reclaimed rubber is completely used; but in actual production, few people use the tire reclaimed rubber in light-colored rubber products. Does it mean that the tire reclaimed rubber cannot play a role in light-colored products? If so, what should you pay attention to during use1JLYY729?
There are differences in the color and index of general rubbers such as natural rubber, styrene-butadiene rubber and butadiene rubber of different varieties and different grades. Black rubber can be used to produce light-colored rubber products, and more attention can be paid to color matching. In theory, black tire reclaimed rubber can produce light-colored rubber products, and the following problems need to be considered in the application process.
1. Low-cost light-colored rubber products should not use tire reclaimed rubber
Rubber products manufacturers use tire reclaimed rubber to produce rubber products with the purpose of reducing production costs. Rubber products such as ordinary rubber sheets and rubber miscellaneous parts can usually use tire reclaimed rubber in large quantities, but the cost of color matching is high when producing light-colored rubber sheets and miscellaneous pieces. The use of tire reclaimed rubber to reduce costs has lost its original meaning. Therefore, low-cost light-colored reclaimed rubber products should not use tire reclaimed rubber. In this case, try low-glued white latex reclaimed rubber (white reclaimed rubber).
2. Light-colored rubber products should choose environmentally-friendly tire reclaimed rubber
If the tire reclaimed rubber is selected in the production process with contaminated rubber oil or rubber softener which is prone to migration, the product is also prone to discoloration and migration problems in the production of rubber products, the most common being yellowing. This phenomenon is less noticeable in black and dark rubber products, but it affects the appearance of the product in light-colored rubber products. Therefore, when using tire reclaimed rubber to produce light-colored reclaimed rubber products, it is necessary to pay attention to selecting environmentally-friendly tire reclaimed rubber and not regenerating tire reclaimed rubber to avoid serious discoloration of light-colored rubber products during production, parking and use.
3. When mixing tire reclaimed rubber in light-colored rubber products, attention should be paid to the type of compounding agent.
The type and color of various compounding agents in the rubber product formulation will also affect the color of the product, especially the reinforcing agent and filler which are second only to rubber, and should not be used in a large amount in the formula of light-colored rubber products containing tire reclaimed rubber. Black rubber reinforcing agent and filler. It is not advisable to use rubber softeners and rubber processing oils which are prone to discoloration and migration, and it is not possible to use polluting anti-aging agents.
In the actual production and processing process, tire reclaimed rubber can be used in the production of light-colored rubber products. In the course of use, attention should be paid to the selection and dosage of tire reclaimed rubber and the type and amount of compounding agent in the formula of light-colored rubber products containing tire reclaimed rubber. It can reduce the cost of rubber compound without burdening the color matching cost.
