When producing colored rubber flooring, floor mats and other products, light-colored or middle-colored floor-to-ceiling natural rubber is usually selected as the main raw material, and a small amount of natural rubber or latex reclaimed rubber is added to improve the mechanical properties of the product. Ground natural rubber and latex reclaimed rubber are ideal raw materials to replace natural rubber in the production of rubber products, which can significantly reduce the cost of rubber raw materials. For the production of molded rubber products, if high rubber content and excellent mechanical properties are required, floor-to-ceiling natural rubber should be chosen; if the rubber content is not high, low latex latex reclaimed rubber can be used to replace part of the natural rubber to reduce costs. When used in the production of translucent rubber products or tendon soles, light-colored floor rubber is usually chosen instead of natural rubber. In order to improve the performance of floor-to-ceiling natural rubber products, it is often used together with other rubbers such as styrene-butadiene rubber, isoprene rubber, neoprene, etc., in order to give full play to their respective advantages and improve the overall performance. Whether it is to choose ground natural rubber or latex reclaimed rubber, as well as the specific type and dosage, it must be determined according to the requirements of the rubber product itself, in order to achieve the purpose of cost minimization and quality optimization.

10 kg of light-colored natural rubber, 30 kg of white latex reclaimed rubber, 3 kg of styrene-butadiene rubber, 35 kg of light calcium carbonate, 2 kg of white carbon black, 5-8 kg of white mineral oil, and 0.8 kg of coumarone , 0.4 kg of paraffin, 0.8 kg of stearic acid, appropriate amount of color mother oxygen according to the color; 1.5 kg of zinc oxide, 0.3 kg of accelerator M, and 0.2 kg of accelerator DM. Accelerator TMTD 0.1 kg, sulfur 1.3 kg; vulcanization temperature 145 ℃, vulcanization time is adjusted according to the thickness of the product.

1. Light-colored floor-to-ceiling natural rubber has high rubber content, low price, light color, and is suitable for the production of colored rubber products;

2. White latex reclaimed rubber is used to improve the mechanical properties and elasticity of colored rubber sheets;

3. The amount of carbon black should not be too large, too large will easily affect the color of the product;

4. The ratio of ground natural rubber to other rubber and additives can be adjusted appropriately according to product performance requirements and price changes. For example, if high mechanical properties are required, the amount of ground natural rubber or latex reclaimed rubber can be increased; if low cost is required, the amount of light calcium carbonate can be increased.

5. During the production process, each component should be fully mixed to fully integrate them to ensure stable product quality. At the same time, the production process must be strictly controlled, such as heating temperature, mixing time, etc., so as not to affect product performance.

To produce cost-effective colored rubber products, the key is to select the main and auxiliary materials. At the same time, the formula must be carefully designed and the production process controlled, so as to maximize the role of each component and achieve the production goal of the lowest cost and the best quality. . Ground natural rubber and latex reclaimed rubber are the main raw materials to replace natural rubber to reduce the cost of rubber products, but each has its own characteristics. It is necessary to choose different types and different proportions according to the requirements of specific products for use, and cooperate with styrene-butadiene rubber to improve tear resistance Strength, in order to achieve good cost control and quality effect.
