Embodiment Construction

[0030] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0031] like Figure 1 to Figure 4 Shown, a kind of preparation method of modified universal plastic masterbatch, it has used a kind of screening equipment, and this screening equipment comprises conveying frame 1, interface frame 2, screening unit 3, docking frame 4, granulation head 5 and Connector 6, using the above-mentioned screening equipment to prepare the modified general-purpose plastic masterbatch as follows:

[0032] S1. Stirring and placing: Stir and melt the plastic raw materials to form a molten mixture, and put the molten mixture into the frame 11;

[0033] S2. Insula...

Abstract

The invention provides a preparation method of modified universal plastic master batches. The preparation method is completed by cooperation of a conveying frame, an interface frame, a sieving unit, abutt joint frame, a granulation head and a connecting piece. The preparation method can solve the problems that when a uniformly mixed mixture is heated and melted, a small amount of impurities may be mixed into the mixture; due to the fact that the impurities are difficult to separate out, the impurities may block a granulation head during later conveying, extrusion and granulation; no special screening equipment is provided for impurity filtering in the existing mixture conveying process; and meanwhile, the molten mixture may be solidified in advance in the conveying process, so that the situation that a machine is difficult to granulate due to blockage is caused, and the granulation head is directly damaged under a severe condition.

Description

technical field [0001] The invention relates to the technical field of plastic masterbatch preparation, in particular to a preparation method of modified universal plastic masterbatch. Background technique [0002] Plastic is popular because of its light weight and fast molding. Plastic masterbatch is the traditional Chinese medicine factor for molding various products. Before molding finished products, it is often necessary to mix plastic powder with some functional powder. After mixing evenly The mixture is heated and melted, and then the plastic masterbatch is extruded through the granulator. When the mixed mixture is heated and melted, a small amount of impurities may be mixed into it. Since the impurities are difficult to be separated, in the later stage During conveying and extruding granulation, the impurities in this part may block the granulation head, and the existing mixture conveying is not equipped with special screening equipment to filter impurities. At the sa...
