Problems solved by technology

[0004] At present, calcium carbonate is the most widely used inorganic filler in the research of filling modification of plastics and their products, but its oil absorption value is high, the product has high light absorption, the product surface will show sub-surface and matte effects, and the filling amount is too large. The mechanical properties of the product are seriously reduced, and often cannot meet the needs of high toughness, high mechanical strength, and high toughness products

Embodiment 1

[0035] The present invention is a sodium sulfate plastic filled modified transparent masterbatch, including the following components in parts by weight:

[0036]

[0037] The preparation of the filling masterbatch is carried out according to the method described in the technical scheme of the present invention: 78 parts of sodium sulfate are added to a high-speed mixer, stirred at high speed (rotation speed is 2500 revolutions / min) and heated to 105°C, heated for 6 minutes and then added 1.2 Part of sodium stearate was reacted for 5 minutes, then 2.5 parts of aluminate coupling agent DL-411 was added and mixing was continued for 15 minutes. Then put the materials into a low-speed mixer (rotating speed of 800 revolutions / min), add 23 parts of polypropylene, 4 parts of paraffin wax and 1.3 parts of maleic anhydride grafted polystyrene, mix and stir for 10 minutes, and then discharge. Finally, the mixture is extruded by a twin-screw with a barrel temperature of 200°C, hot-cut, and a...

Abstract

The invention relates to sodium sulfate plastic filling modified transparent masterbatch and belongs to the technical field of plastic processing and molding. The sodium sulfate plastic filling modified transparent masterbatch comprises the following components in parts by weight: 60-95 parts of sodium sulfate, 0.3-2 parts of a surfactant, 1-5 parts of a coupling agent, 0.5-3 parts of a compatilizer, 15-30 parts of carrier resin and 3-6 parts of a dispersant. By adopting sodium sulfate as inorganic filler, the filling effect is good, the cost is low, and good environment-friendly property, transparency and glossiness are achieved; and as the surfactant and the compatilizer are added in the raw materials, the compatibility of inorganic filler and resin can be favorably enhanced. The sodium sulfate plastic filling modified transparent masterbatch prepared from the raw materials dislcosed by the invention has the characteristics of low density, good appearance dispersibility, tensile strength, elongation at break, film tearing strength, shock resistance and other mechanical properties, as well as strong environment-friendly property, and is high in practicability and performance cost ratio.

Description

Technical field [0001] The invention belongs to the technical field of plastic processing and molding, and particularly relates to a filling masterbatch for modifying plastics, specifically a sodium sulfate plastic filling modified transparent masterbatch. Background technique [0002] With the development of social economy and the improvement of people’s living standards, the application fields of plastic products are also expanding, ranging from various shopping bags, garbage bags, plastic buckets and packaging bags commonly used in daily life, to automobiles, home appliances, In the communications, high-end tools and other industries, the application fields of plastic products are constantly expanding, but they are also slowly developing into the high-level industry fields. Compared with ordinary application industries, the high-level fields have higher quality requirements, which require better quality of plastic products. . [0003] In order to improve the performance of plas...
