What raw materials do black masterbatch need?In the process of plastic products processing, almost everyone has used black masterbatch, for dyeing, aging prevention, conductive products, etc.However, we will encounter various problems during the use process, which will perplex us.The basic components of black masterbatch know what materials are needed in the process for those who have a good understanding of plastic products. Black masterbatch is very important in plastic products.

Composition of black masterbatch: materials include carbon black, carbon black carrier, carbon black wetting agent, carbon black dispersant and other processing agents.

According to the international classification, there are more than 30 varieties in China.Mainly rubber and non rubber two categories.In the dyeing of plastic products, black masterbatch as long as 0.6-0.8% will be extremely black, and if it is added too much, it will not be blacker.If you need to rely on black masterbatch anti-aging needs, as long as the use of brown masterbatch anti-aging.

The carrier is the matrix of black masterbatch, and the special color masterbatch generally chooses the same resin as the product resin as the carrier. The compatibility between the two is the best, but the fluidity of the carrier should also be considered.

What is the raw material of black masterbatch?

Ink method: the pigment surface is covered with a layer of low molecular protective layer by three roll grinding. After grinding, the fine color paste is mixed with the carrier resin, and then plasticized by two roll plastic mixer, and then granulated by single screw or twin-screw extruder.

Kneading method: the pigment and oil carrier are mixed and then the oil is kissed by the pigment. The raw material is washed from the hand phase to the oil tank by kneading.At the same time, the oil carrier can cover the pigment, which can disperse and stabilize the pigment, and prevent the pigment from agglomerating.

Washing method: the pigment, water and dispersant are grinded by sand to make the pigment particles smaller than 1 μ m, and the pigment is transferred into the oil tank by phase transfer method, and then dried to prepare the color masterbatch. Organic solvent and corresponding solvent recovery device are required for phase transfer.

In any anti-aging requirements of outdoor products, containing calcium carbonate is not good, depending on the service life of the product to choose whether to use.
