Embodiment 1

[0016] Materials taken by weight: Yuanming powder 75kg, linear low density polyethylene 10kg, ethylene vinyl acetate copolymer 8kg, polyethylene wax 3kg, zinc stearate 2kg, stearic acid 0.5kg, aluminate coupling agent 1kg, titanium Acid lipid coupling agent 0.5kg.

[0017] Add the Yuanming powder into the high-speed mixer and heat it to 110°C, then add the coupling agent for coating three times, then add polyethylene wax, soap salt, fatty acid, and then add linear low-density polyethylene and ethylene vinyl acetate. The copolymer is mixed evenly and discharged, then transferred to the crusher for cooling and crushing; the obtained mixture is put into a co-rotating twin-screw extruder with an aspect ratio of 32-48, and plasticized and granulated at 140-180°C Eagerly cut and air-cooled to make granular masterbatch, and screen the masterbatch to get the finished product.

Abstract

The invention discloses a polyolefine full transparent master batch and a preparation method thereof; wherein, the weight percentage of the components of the polyolefine full transparent master batch is as follows: 70 to 80 percent of glauber salt, 4 to 15 percent of linear low density polyethylene, 4 to 10 percent of ethylene vinyl acetate copolymer, 2 to 3 percent of polyethylene wax, 1 to 2 percent of soap salt, 0.5 to 1 percent of fatty acid and 1 to 2 percent of a coupling agent. The preparation method of the master batch of the invention includes the following steps: after being added into a highly mixing machine, stirred with high speed and heated to 110 DEG C, the glauber salt is added with the coupling agent for three times for coating; then the polyethylene wax, soap salt and the fatty acid are sequentially added; then the linear low density polyethylene and the ethylene vinyl acetate copolymer are added, mixed uniformly and discharged; the components are transferred into a crusher to be cooled and crushed; finally, the premixed materials are extruded into granular master batches in a co-rotating twin screw extruder with the length-diameter ratio of 36 to 48. The polyolefine full transparent master batch has lower density, good dispersion, opening property and color, excellent optical property and very high economy and is widely used in blow-molded, extrusion and injection-molded products.

Description

Technical field: [0001] The invention relates to a polyolefin fully transparent masterbatch and a preparation method thereof, and belongs to the technical field of masterbatch manufacturing in which inorganic powders and polymer materials are combined. Background technique: [0002] Worldwide, polyethylene and polypropylene are the two most widely used basic resins in plastic products. About one-half of all plastic products. In 2007, China consumed about 20 million tons of polyethylene and polypropylene. On the one hand, with the increasing awareness of environmental protection, the voice of seeking to solve white pollution is gradually rising, and inorganic powder modified high molecular polymer is an effective method. For example, the national standard of Japanese convenience bags requires that the calcium carbonate content must be more than 30%, which not only saves limited petroleum resources, but also is conducive to environmental protection. Incineration does not emi...
