Description
Technical field
The present invention relates to field of plastic coloring, relate to a kind of Vestolen PP 7052 Masterbatch and preparation method thereof specifically.
Background technology
Vestolen PP 7052 is one type of output maximum, uses macromolecular material very widely, and its abundant raw material is cheap, machine-shaping easily, high comprehensive performance.Often use Masterbatch painted in the Vestolen PP 7052 process of manufacture to it.Masterbatch is made up of pigment, vector resin, auxiliary agent.When adopting Masterbatch painted, the problem of appearance is Masterbatch and base-material separate easily in mixing, material loading, blanking process the most easily, causes in the production of articles process phenomenons such as color and luster is inhomogeneous, inconsequent.
Masterbatch and base-material through different manufacturers being used for polypropylene color are tested, and the ASG of Masterbatch is bigger, on average at 1.2g/cm
3More than, the look female proportion that white etc. contain mineral dye is bigger, and the proportion of base-material is on average at 0.92 g/cm
3About.Because of the Masterbatch consumption is few, only can adopt the strict control spice time usually by rule of thumb, hand-fed, when finding that in start process color is thin out, intermittence is sprinkling upon the surface with the look mother and improves the color and luster difference on hopper top immediately.In view of workman's professional skill is different, the goods of making still exist irregular colour to spare phenomenon, waste lot of manpower and material resources simultaneously.
Summary of the invention
