Latex reclaimed rubber is processed from natural rubber waste rubber cups, rubber filaments, waste rubber materials and waste latex reclaimed rubber. It has high mechanical strength, good resilience, and good wear resistance. It is a substitute for natural rubber in the production of cloth rubber shoes. Ideal raw material for shoe soles. When latex reclaimed rubber is used as the main raw material to produce light-colored cloth rubber shoe soles, white latex reclaimed rubber with high rubber content is generally used, which is easy to match colors and ensures that the soles do not migrate or change color. The following editor will share with you the application skills of latex reclaimed rubber in the sole of light-colored cloth rubber shoes.

1. Application of latex reclaimed rubber in the sole of light-colored cloth rubber shoes

The raw materials of latex reclaimed rubber include waste natural rubber, waste latex products, etc. Among them, pure latex reclaimed rubber products have high rubber content, good elasticity, small specific gravity, and good compatibility with butadiene rubber. It is a substitute for butadiene rubber to produce cloth. Ideal raw material for rubber shoes. Among them, white pure latex reclaimed rubber can be used in the processing of light-colored and colored cloth-covered rubber shoe soles, which can reduce the cost of rubber materials, improve process performance, and ensure product indicators. The price of pure latex reclaimed rubber products is significantly lower than that of butadiene rubber. Substituting butadiene rubber can reduce the cost of rubber sole materials; in the production process, it is easy to masticate after multiple processes such as crushing, desulfurization, and molding, which can improve to a certain extent. The processing technology can reduce the production energy consumption of cloth rubber shoe soles; the proper amount of pure latex reclaimed rubber can not only reduce the production cost, but also ensure that the rubber soles are qualified. It is an ideal substitute raw material for cloth rubber shoe soles.

2. Key points of color matching for the sole of rubber shoes with latex reclaimed rubber

When using latex reclaimed rubber to produce light-colored cloth rubber soles, attention should also be paid to color matching. Generally, it is considered from three aspects: the rubber raw materials used, the selection of rubber pigments and the three primary colors. When latex reclaimed rubber is used to produce white and light-colored cloth rubber shoe soles, it is recommended to use white and light-colored latex reclaimed rubber and rubber compounding agents, and choose non-polluting or low-polluting products, which will not change color during vulcanization and will not produce polluting products ; When preparing the white sole of cloth rubber shoes with latex reclaimed rubber, it is recommended to add a small amount of white coloring agent to adjust the white background color and facilitate coloring.

Rubber pigments are usually divided into two categories: inorganic pigments and organic pigments. In general, inorganic pigments have good heat resistance, light resistance, strong hiding power, and excellent solvent resistance. Compared with the inorganic pigment HYL3Y3YESYC, the organic pigment has the advantages of more varieties, bright color, strong tinting strength, good transparency, and less dosage, but its heat resistance and organic solvent resistance are poor. When choosing rubber pigments for cloth-covered rubber shoe soles with latex reclaimed rubber as the main raw material, not only should you consider the bright color, light fastness, and durability, but also the content of harmful metals (especially copper, manganese, and cobalt) in rubber pigments. . It is recommended to choose rubber pigments that have passed through a 100-mesh sieve.

The three primary colors of rubber pigments are red (red), yellow, and blue (cyan). Various colors such as orange, purple, and green can be obtained by mixing different pigments of the three primary colors. That is, red and blue are mixed to make purple; blue and yellow are mixed to make green; yellow and red are mixed to make orange; the three are mixed in equal amounts to make black. Using the three primary colors to change and cooperate with each other, any color can be obtained.

When using latex reclaimed rubber to produce cloth rubber shoe soles of different colors, it is necessary to choose different types of rubber pigments. The editor will continue to discuss related issues with you later.
