Abstract

The invention aims to solve the problem that the density and the weight of talcum powder filling master batch are increased in the prior art, provides talcum powder filled foaming master batch and a preparation method thereof, and belongs to the technical field of plastic material modification. The talcum powder filled foaming master batch is prepared from the following raw materials: EVA resin, afoaming agent A, a foaming agent B, a foaming agent C, a nucleating agent, talcum powder, a foaming accelerator, a processing lubricant and a processing heat stabilizer. High-silicon-content talcum powder obtained by calcining is added into common talcum powder master batch, the talcum powder is used as a nucleating agent, a composite foaming agent is used as a foaming agent, and a foaming filling product with uniform and fine pores can be obtained by filling the master batch into a plastic material. Due to the adoption of the composite foaming agent, the foaming temperature of the product iswidened so that a high-performance foaming filling product is obtained.

Description

technical field [0001] The invention belongs to the technical field of plastic material modification, and in particular relates to a foaming masterbatch filled with talcum powder and a preparation method thereof. Background technique [0002] Talc powder masterbatch is a kind of plastic modified filler, which refers to the granules formed by mixing and granulating with polymer or other carriers as the main component is talc powder. [0003] Talc powder has become an important inorganic mineral filler in plastic modification, and has been paid attention to in the research and application of filled modified plastics. Talc powder filled modified plastics have good appearance quality, low shrinkage and higher heat distortion temperature compared with unfilled talc powder materials. Plastic modified materials are characterized by light weight, low price, easy processing, mature modified products, recyclability, and excellent comprehensive performance. Their products have huge ma...
