Ordinary rubber hose outer rubber generally has no special requirements for aging resistance, heat resistance and oil resistance. It is mainly prepared by using tobacco sheet glue and styrene-butadiene rubber in natural rubber as the main raw material; reclaimed rubber is to reduce the production cost of rubber products. New rubber raw materials, but the reclaimed rubber on the market is mainly made of black products. Can it be used in the production of red rubber hose outer layer to achieve the purpose of reducing costs? Which reclaimed rubber is more suitable for the preparation of red ordinary rubber hose outer rubber?
1. Reclaimed rubber can be used to produce red ordinary rubber hose
In actual production, rubber products with natural rubber and styrene-butadiene rubber as the main raw materials generally choose latex reclaimed rubber or tire reclaimed rubber to reduce the cost. This is because the two reclaimed rubbers have similar properties to natural rubber, and natural rubber and styrene-butadiene. The rubber has good compatibility and can replace the natural rubber 1JLYY1029 to produce rubber products. If the color problem is not considered, latex reclaimed rubber and tire reclaimed rubber can theoretically replace a certain proportion of natural rubber and reduce the production cost of rubber tube outer rubber compound.
2. Which kind of reclaimed rubber is better for red ordinary rubber hose outer layer glue?
Latex reclaimed rubber on the market includes black latex reclaimed rubber, white latex reclaimed rubber and color (including red, green, yellow, etc.) latex reclaimed rubber. The tire reclaimed rubber is basically black. From the formulation point of view, if the black rubber is adjusted to red, the coloring is difficult, and a high-priced colorant is required. Therefore, it is not recommended to use a black LT reclaimed rubber to prepare a red rubber hose sheath.
The white latex reclaimed rubber in the latex reclaimed rubber is light in color and white in color, and the price is lower than that of natural rubber. All or part of the natural rubber is used to produce various light-colored and colored rubber products. The color matching is easy, and the cost is obviously reduced; the red in the latex reclaimed rubber Latex reclaimed rubber is mostly made of waste rubber such as red latex balloon. The color is positive. It is used to replace the natural rubber to produce red rubber hose. The outer rubber color is easier to match, and there is basically no whitening and yellowing during parking and use. Discoloration problem.
Considering the combination of color and cost, when using recycled rubber to reduce the outer rubber of red rubber hose produced by natural rubber/styrene-butadiene rubber, Xiaobian recommends that manufacturers use white latex reclaimed rubber and red latex reclaimed rubber, if red latex reclaimed rubber products There are products that are closer to your product specifications, and it is more appropriate to use red latex reclaimed rubber.
