1 Introduction Masterbatch

Concept

Color masterbatch is 60s of the 20th century, the development of a plastic, fiber coloring of new products, by the high proportion of pigments and additives and thermal plastic resin, the well dispersed and plastic colorant.

 

Resin masterbatch in the selection of the colorant with good wetting and dispersion, and coloring material with good compatibility.

 

Special masterbatch: according to the user specified for varieties of plastic products, choose the same plastic as the carrier of the manufacturing of color masterbatch. Such as PP and ABS respectively by PP Color Masterbatch, ABS as carrier.

 

Universal masterbatch: with a resin (often with a low melting point PE) as a carrier, but it can apply to other resin in addition to the carrier resin coloring.

Color = carrier+ pigment+ dispersant

 

A. pigment

Pigment is divided into organic pigments and inorganic pigments.

 

The commonly used organic dyes: phthalocyanine red, phthalocyanine blue, phthalocyanine green, fast scarlet, large molecular red, macromolecules yellow, permanent yellow, permanent purple, azo red.

 

Commonly used inorganic pigments are: cadmium red, cadmium yellow, titanium dioxide, carbon black, iron oxide red, iron oxide yellow, etc.

 

B. carrier

 

The carrier is the matrix of masterbatch. Special masterbatch generally choose with resin product of the same resin as carrier, both has the best compatibility, but also to consider the carrier mobility.

 

C. dispersant

 

The dispersing agent can cause the pigment to disperse evenly and no longer aggregate, and the melting point of the dispersing agent is lower than that of the resin, the resin has good compatibility, and the pigment has good affinity. The most commonly used dispersant is: low molecular weight polyethylene wax, stearic acid salt.

 

In 2 China masterbatch industry

With great development in recent years, China's plastics, masterbatch production has maintained a sharp growth, from 2000 the annual output of 7 million tons to 2006 the annual output of 30 million tons, 60 million tons of annual output in 2009, the output value of more than 100 billion yuan. China color masterbatch products annual output growth rate for many years to maintain more than 20%, significantly higher than the global average level, has become Asia's first color masterbatch production country.

 

3 China masterbatch industry enterprise distribution

By the end of 2009, China Professional Committee of masterbatch on China's main 251 masterbatch production enterprises statistics (the 251 enterprises in total output accounted for China's Masterbatch industry annual output of 96%), the 251 masterbatch production enterprises mainly concentrated in Guangdong, Jiangsu, Zhejiang, Shanghai a band, especially with more than 1000 tons of large enterprises gathered in the south, the northern region of Shandong is part of the manufacturers, the Midwest area manufacturers less.

 

Till the end of 2009, more than 251 masterbatch production enterprises annual total production capacity reached more than 24 million tons, which 53 large manufacturers production capacity accounted for more than 60% of the total production capacity. According to the geographical distribution, China masterbatch production showed strong weak north south, East West weak trend.
