Abstract

The invention relates to a composite processing additive for a plastic thin film and a preparation method thereof. The composite processing additive is prepared from the following components in percentage: 0.5 to 0.8% of diameter expanding agent, 1.2 to 1.8% of emulsifier, 3 to 5% of antioxidant, 15 to 25% of filling agent, 3 to 5% of slipping agent, 5 to 10% of activator, and the balance of water. The preparation method comprises the following steps of S1, preparing raw materials; S2, preparing the emulsifier; S3, preparing a processing additive mixed solution; S4, aging. The composite processing additive has the advantages that the cost is low, the application range is broad, and the stability is good.

Description

technical field [0001] The invention relates to the technical field of plastic additives, in particular to a composite processing additive for plastic films and a preparation method thereof. Background technique [0002] The global plastics industry is developing very rapidly, with an average annual growth rate of 4%-6%, exceeding the growth level of global GDP. The main reason for this growth is that plastic materials continue to replace traditional materials such as metal, wood, and minerals. In fact, the various additives added to the resin are also of great help to the successful application of plastic materials. Among the various types of additives used, polymer impact modifiers and processing aids provide the most unique and valuable excellent properties for polymers, and at the same time improve the processing performance of products. Many thermoplastic resins have excellent physical properties and high service temperature, however, their melt viscosity is usually h...
