Abstract

The invention relates to an environment-friendly modified master batch and process for preparation, the product can not only reduce the cost of production, but also enhance mechanical property of filling plastics, and has the advantages of simple technique preparing of the preparation, good fluidity of the prepared master batch and easy forming. The environment-friendly modified master batch comprises the following components by weight: heavy calcium carbonate of 2000-3000 mesh sizes, linear low density polyethylene, polyethylene wax, corrdination type titanate coupling agent, thinner, compound wax, zinc stearate grease, calcium stearate and auxiliary agent. The process for preparation of the invention is that the heavy calcium carbonate of 2000-3000 mesh sizes is placed in a mixer under the rapid of 200-300 r / min to mix for 15 minutes, the corrdination type titanate coupling agent and the thinner are charged to churn up for 5-10 minutes, and then the rest raw materials are charged for mixing 1-3 minutes to obtain mixture, the mixture is placed in a co-rotating twin-screw granulator for granulating, hot cutting, cooling and packing to prepare the environment-friendly modified master batch.

Description

technical field [0001] The invention relates to an environment-friendly modified masterbatch and a preparation method thereof, which are mainly used for processing plastic products. Background technique [0002] With the rapid development of the plastics industry and the wide application of plastic products, the filling modification technology of plastics has been paid more and more attention by people. Plastic products use a lot of resin, and the price of resin also increases after the price of oil rises. Facing the price increase of plastic raw materials, plastic manufacturers rely on plastic modification to solve the problem, and modified masterbatches are produced accordingly. Modified masterbatches are mainly heavy calcium carbonate masterbatches and light calcium carbonate masterbatches, but the mechanical properties of plastic products filled with light calcium carbonate masterbatches drop too much, which affects the quality of plastic products.
