Latex reclaimed rubber is processed from natural rubber waste rubber cups, rubber wires, waste latex gloves, latex finger covers, etc., with the basic performance characteristics of natural rubber, good elasticity and high mechanical strength, and completely or partially replaces natural rubber to produce rubber products, such as rubber soles, rubber toys, children's carriage tires, etc., effectively reducing the cost of raw materials. When using latex reclaimed rubber to produce brightly colored rubber products, color matching is crucial.
1. Latex reclaimed rubber production of bright color rubber products color matching elements
(1) Rubber pigment choice
Rubber pigments are generally divided into organic pigments and inorganic pigments, and inorganic mineral pigments are recommended.
(2) Rubber processing technology
The color of rubber products is the result of the reaction of various components of pigments and rubber compounds, and the processing temperature, time and pressure will have an impact on the color of the products.
(3) Raw rubber background color choice
When choosing raw rubber for bright rubber products, it is recommended to choose latex reclaimed rubber and natural rubber with light background color while taking into account the requirements of physical and mechanical properties, and can be used in combination with synthetic rubber if necessary, such as white latex reclaimed rubber, white crepe flakes, butadiene rubber, etc., which are easy to match colors and not easy to change color.
2. The principle of color matching for the production of bright rubber products by latex reclaimed rubber
(1) Rubber compounding agent choice
When using white latex reclaimed rubber to produce bright rubber products, it is recommended to use non-polluting vulcanization accelerators and antioxidants as much as possible under the premise of meeting the physical and mechanical property requirements, such as accelerators D, CBS, MBT, antioxidants MB, 2246, 264, SPC; Use light or white fillers, such as silica, white Yanhua, etc.; Choose plasticizers and softeners that are transparent and colorless or light-colored and non-contaminating, such as paraffin oil, naphthenic oil, light-colored petroleum resin, liquid nitrile.
(2) Use titanium dioxide in moderation
When using reclaimed rubber to produce bright color rubber products, titanium dioxide can be used in an appropriate amount, and the addition ratio of titanium dioxide can be determined in combination with bright color requirements and cost budget; The use of titanium dioxide is the key to the bright color of bright rubber products.
(3) Self-made master rubber
The flying pollution of pigments has a great impact on the color of the rubber compound, and the organic colorant is not easy to disperse evenly, so in order to avoid color difference, it is recommended to make the masterbatch rubber.
(4) Simplify color matching pigments
All the colors in the world are derived from the three primary colors, original red, original blue, original yellow, red + blue = purple, red + yellow = orange, blue + yellow = green, red + blue + yellow = black, dark + titanium dioxide = light color; Small changes in the proportions of the three primary colors can E4LYY1224 form a myriad of colors. Since the more varieties of color are added, the more complex and difficult it is to control the factors that affect the final color; Therefore, when using latex reclaimed rubber to produce bright rubber products, it is necessary to grasp the three primary colors to simplify the color matching process and stabilize the production of bright color rubber products.
When white latex reclaimed rubber is produced in bright rubber products, the choice of colorants and raw materials also needs to consider cost and other factors. In the production of bright rubber products, it is recommended to use a small plate vulcanizer or vulcanizer to simulate the actual production temperature and time, obtain a color matching style, make the color of the pattern consistent with the demand, and then carry out continuous large-scale production according to the formula plan.
