Abstract

The invention discloses polypropylene master batches and a preparing technology thereof. The polypropylene master batches are prepared from polypropylene, talcum powder, an antioxidant, a lubricatingagent and an additive. The preparing technology comprises the following preparing steps that 1, the polypropylene and the talcum powder which are weighed are dried; 2, the dried polypropylene, the dried talcum powder, the weighed antioxidant, the weighed lubricating agent and the weighed additive are mixed and subjected to banburying, and thus mixed materials are obtained; then, the mixed materials are added to an extruder to be subjected to mixed extrusion processing, cooling, pelletizing and demagnetization, and thus particle materials are obtained; 3, the cut particle materials are dried, screened by a material sieving machine, and sealed and stored by a seal bag. The polypropylene master batches and the preparing technology thereof are provided for improving the problems that in the prior art, polypropylene products are not even in hardness, low in sticky performance, poor in appearance and complex in production process; by the adoption of the technical scheme, the prepared polypropylene master batches have the advantages of being good in stainability and easy to demould, and the plastic products are high in strength and resistant to thermal deformation.

Description

technical field [0001] The invention relates to a plastic processing master batch, in particular to a polypropylene master batch and a preparation process thereof. Background technique [0002] Masterbatch (English name Masterbatches) full name plastic masterbatch, alias masterbatch is a kind of plastic processing aid developed and stood up in the 1980s. It is composed of excessive chemical additives, carrier resin and dispersant. . Masterbatch is an aggregate obtained by uniformly loading super-normal pigments (dye) in resin. In the plastic processing and molding process, for the convenience of operation, the required various additives, fillers and a small amount of carrier resin are mixed and kneaded first, and then measured, mixed, melted, extruded, and pelletized by extruders and other equipment Pellets made during processing. Masterbatch is generally composed of carrier resin, various fillers and various additives. The limit of additives or the content of filler in ...
