Polypropylene because of its light weight, corrosion resistance, high strength, hydrophobic warmth and low cost of the characteristics of China has been rapid development. Because of the lack of pro-chromogenic groups on the macromolecule chains of polypropylene, there is no intermolecular effect on the raw materials. It is difficult for the dye molecules to diffuse in the molecule, which is prone to bleed and migrate, thus affecting the product quality.

Although large-scale production at home and abroad are based on the melt method of masterbatch coloring, but most do not fundamentally solve the pigment molecules and fiber molecules affinity, polypropylene dyeing difficult problem still exists, to a certain extent, Development and its application in many fields. In order to overcome the above performance defects, today, Jin Cai for everyone to introduce the production of polypropylene masterbatch additives in the choice.
1 choice of pigment
As the production process of polypropylene demanding, requiring the pigment must have heat resistance, resistance to migration, fineness, easy to disperse the characteristics of the above requirements and can use polypropylene pigment is not much, most domestic manufacturers or their own pigment processing or Direct use of pre-dispersed pigments. The use of Swiss imports Yan Jiali series of pigments, pre-dispersed treatment and then charge production, to ensure the superior performance of the pigment, while the smaller diameter, so as to achieve a good purpose of dispersion.
2 carrier selection
As the polypropylene spinning speed, the matrix resin molecular weight and its distribution and ash and other indicators have strict requirements, some domestic manufacturers using the United States Philip K resin, DuPont EVA-565 and South Korea's Samsung EVAE-141, etc. As the carrier, the effect is ideal.
3 choice of dispersant
At present, most domestic manufacturers are using low molecular weight PE wax as a pigment dispersant. Because of its use of pyrolysis production, low dispersion temperature, impurity and affect the quality of masterbatch, some manufacturers use BASF to provide polymerized low molecular weight wax, but the price is more expensive. Some manufacturers use domestic low molecular weight polypropylene wax as a dispersant, which is characterized by PP wax softening point, oxidized PE wax molecular chain with a certain amount of shuttle base and through the base, and pigment and resin compatibility is better than low molecular PE wax.
4 selection of affinity agents
In the formula, adding the affinity component is a prominent feature of this paper. Its role is to improve the pigment molecules and PP macromolecular chain of chemical effects, thereby reducing the pigment "spray cream" and migration phenomenon.

Zhejiang Jincai New Material Co., Ltd. was established in 2009, is a professional engaged in the development of color masterbatch production enterprises. The company occupies 63 acres, a plant 25000m ², two plants about 20000m ², a total of eight. The company has 30 advanced production lines, with an annual output of 20,000 tons of masterbatch, the main production of high-quality polyester masterbatch, polypropylene masterbatch, nylon masterbatch, plastic masterbatch, functional masterbatch, and has been committed to high, , The new and special masterbatch research and development and production, and national defense scientific and technological research units and institutions of higher learning jointly developed the leading chemical fiber conductive masterbatch, national defense military masterbatch, three anti-sweat masterbatch, color masterbatch, radiation shielding Masterbatch and so on.

The company widely selected at home and abroad in the senior colorants, the use of advanced equipment and strict laboratory testing means to complete the product chromatography, color group science, good spinnability, high color fastness. And through the matching spinning proofer, injection molding machine, computer color measuring instrument, DF value detector and a series of development testing equipment, to sample color, production, marketing and services are in accordance with the ISO9001: 2008 quality management system implementation. Has a strong sales service team, improve the management and after-sales service.
