Manufacturing method of Automotive Wiring Harness Protection Sleeve

Automotive Wiring Harness Protection Sleeve, a tube made of latex material with different thicknesses, has the characteristics of high elasticity and high tensile force, not easy to break, natural and non-toxic, etc. It is widely used in medical treatment, toys, electronic equipment, and laboratory tests and other fields. The natural Automotive Wiring Harness Protection Sleeve is produced by a certain process of liquid cut from the rubber tree. Its original color is the original color, but the Automotive Wiring Harness Protection Sleeve in real life is a variety of colors, so how to make the Automotive Wiring Harness Protection Sleeve What about? The following editor will explain to you:

1. Coloring by solution method: Dissolve the rubber with its good solvent into a solution of a certain concentration, then add the coloring agent and rubber compounding agents except sulfur into the solution, stir and mix evenly, and dry at a certain temperature to remove the solution , and finally add sulfur on the rubber mixer.
2. Dry powder coloring: directly add the powdery coloring agent and small materials into the rubber, and knead on the open mill. This method has the advantages of simple operation and low cost, but the dust is large during mixing, which pollutes the environment and has color difference.
3. Color paste coloring: Mix the colorant with the liquid compounding agent, grind it with a three-roller machine to make a paste or slurry, and then add it to the rubber in a certain proportion for mixing. This method can prevent dust from flying, and is also conducive to the dispersion of toner in rubber and uniform color.
4. Granule coloring: There are two main methods for preparing colorant granules. The method is the same as the granulation method of other powdery compounding agents, the powdery toner surfactant is moistened first, then melted with wax or melted with resin and extruded to granulate. The second method is to moisten the toner with a surfactant, and then refine the toner particles under the effect of mechanical force to make a dispersion with a certain concentration, and then mix it with latex for co-precipitation, and then roll it into sheets after drying. grain.
5. Masterbatch coloring: This method is to first mix the colorant, some plasticizers and other rubber compounding agents with the raw rubber through an open mill to make a colorant masterbatch with a concentration of about 50%. , and then added to the rubber in proportion to color.
The above are some methods of coloring various colorful Automotive Wiring Harness Protection Sleeve products in real life. I hope it will be helpful to the vast number of Automotive Wiring Harness Protection Sleeve.
