Latex reclaimed rubber can replace natural rubber alone or be used with natural rubber to produce various colored rubber products, to achieve the dual purpose of ensuring quality and reducing costs. Color matching is an important part of the production process of colored rubber products. When latex recycled rubber is used to reduce the raw material cost of colored natural rubber products, rubber product manufacturers must match the color reasonably. So in the actual production, what problems should be paid attention to when designing the formula of color latex products? How can we avoid color errors?
1. Frequently asked questions about color matching of color latex products
When using latex reclaimed rubber instead of natural rubber to produce colored rubber products, if the color of latex products containing bright plastic or metal accessories is dull, it cannot match the color of other accessories in rubber products. The vulcanization of latex reclaimed rubber needs to be carried out under high temperature and high pressure, so the latex reclaimed rubber 2LLYY0416 before and after vulcanization may have a large difference, which is difficult to control; when using latex reclaimed rubber to produce colored rubber products, raw material fluctuations and production process parameters , And climate change may lead to different colors of the rubber compound after color matching; during the color matching process of latex products, the pigment weighing is not accurate, and the color of latex products will have serious colors.
2. Factors affecting the color matching of color latex products
When using latex reclaimed rubber to produce color rubber products, the nature of latex reclaimed rubber, the variety and amount of pigments (mainly divided into organic pigments and inorganic pigments) and production process parameters will affect the color matching of color latex products, and rubber product manufacturers need to pay special attention.
3. How to avoid color aberration in color latex products
When using latex reclaimed rubber to produce color latex products, you can consider the following aspects to avoid color differences in color latex products: ① Select raw latex reclaimed rubber based on the color of the color latex products, such as white latex reclaimed rubber, easy to match colors; ② Use inorganic mineral pigments as much as possible, organic pigments are susceptible to changes due to external factors; ③ Weigh pigments carefully, reject errors, and clean up tools in time; ④ Master the influence of temperature, pressure, and time on colorants, according to the latex reclaimed rubber The processing performance is adjusted reasonably, especially the vulcanization process conditions.
At present, latex reclaimed rubber on the market includes white latex reclaimed rubber, black latex reclaimed rubber and a small amount of red and green latex reclaimed rubber. When rubber products manufacturers produce colorful rubber products, they often use white latex reclaimed rubber. When using white latex reclaimed rubber to produce colored rubber products, rubber manufacturers need to pay attention not only to the color change during the color matching process, but also to comprehensively consider the relationship between the color and other physical and mechanical properties of the product to ensure that the rubber product has a bright color, good performance, and can last for a long time. use.
