CN103172939A - Macromolecule color masterbatch and preparation method thereof - Google Patents

Abstract

The invention discloses a macromolecule color masterbatch which is composed of the following components in percentage by weight: a, 30-60% of carrier resin, b, 5-15% of pigment, c, 4-8% of dispersed lubricant, d, 1-3% of compatilizer and e, 15-25% of other additives. The component e comprises an antistatic agent, a protective agent, a heat stabilizer and an antibacterial agent. The preparation method comprises the following steps of: mixing each component in proportion and placing the mixture in a high-speed mixer; secondly, mixing for 5-20 minutes at the rotate speed of 1000-1500r/min (revolutions per minute); thirdly, carrying out melt blending by adopting a double-screw extruder or an internal mixer as the temperature is at 150-250 DEG C; and fourthly, shearing and mixing by a screw or a rotor as the rotate speed of the screw is 80-300r/min, finally extruding in the extruder, cooling, drying and pelleting to prepare the color masterbatch. The macromolecule color masterbatch has the advantages of anti-static electricity, invariant color, no color loss and uniform color and luster, and the process is clean and environmentally-friendly.

Description

A kind of polymer Masterbatch and preparation method thereof

Technical field

The present invention relates to a kind of polymer Masterbatch and preparation method thereof.

Background technology

The single pearlescence of traditional painted general employing is painted, or adopt the pearly-lustre color master-batch to carry out painted, but toner colorize method, because the process-cycle is long, colour changing is inconvenient, and the shortcomings such as contaminate environment are being given by Masterbatch and replace progressively, and there is function singleness in existing Masterbatch, and in the course of processing, easily destroy the immanent structure of Masterbatch.

Summary of the invention

Technical problem to be solved by this invention be to provide a kind of have antistatic, nondiscoloration, polymer Masterbatch of the not uniform advantage of loss of gloss and color and luster, and the clean environmental protection of the course of processing and preparation method thereof.

The present invention is achieved through the following technical solutions: a kind of novel high polymer Masterbatch is comprised of the component of following weight percentage:

A. vector resin 30-60%, b. pigment 5-15%, c. dispersed lubricant 4-8%, d. compatilizer 1-3%, other auxiliary agents of e. 15-25%;

Described component a is the combination of polystyrene, polypropylene or polyvinyl resin or above-mentioned several resins;

Described components b is titanium dioxide, carbon black, azo pigment or heterocycle pigment;

Described amount of component b is one or more in polyethylene wax, the special-purpose ethylene stearic amide of toner and bright lubrication dispersing agent;

Described component d is polypropylene grafted maleic anhydride or Research of Grafting Malaic Anhydride Onto Polyethylene;

Described component e comprises that static inhibitor, protective agent, thermo-stabilizer and antiseptic-germicide form.

As preferably, the weight percent of each component of described component e is: static inhibitor 20-40%, protective agent 10-23%, thermo-stabilizer 24-43% and antiseptic-germicide 20-30%.

A kind of preparation method of the Masterbatch of polymer according to claim 1 comprises the following steps:

First: each component is deployed in proportion, and insert in high-speed mixer;

Second: under rotating speed 1000-1500r/min, mixed 5-20 minute again;

The 3rd: adopt twin screw extruder or Banbury mixer to carry out melt blending, temperature is at 150-250 degree centigrade again;

The 4th: be under 80-300r/min at screw speed, the shearing by screw rod or rotor, mixing is extruded in forcing machine at last, makes Masterbatch of the present invention through cooling, oven dry, granulation.

The invention has the beneficial effects as follows:

1. antistatic, can prevent general Masterbatch in use because of generation of static electricity absorption and cause the product colour skewness.

2. use protective agent, thermo-stabilizer and antiseptic-germicide, have nondiscoloration, not the uniform advantage of loss of gloss and color and luster.

3. the clean environmental protection of its course of processing.
