Embodiment 1

[0052] Raw materials are taken by weight: 70 kilograms of subnanometer precipitated barium sulfate with an average particle diameter of 100 nanometers, 2.3 kilograms of polyethylene wax, 2 kilograms of stearic acid, 0.3 kilograms of EBS, 0.3 kilograms of zinc stearate, 0.1 kilogram of 1010 antioxidant, Linear polyethylene LLDPE 25 kg.

[0053] Put the sub-nanometer precipitated barium sulfate into the high-speed mixer and heat it to 110°C, then add stearic acid coupling agent for three minutes, then add EBS, zinc stearate, 1010 antioxidant, and finally add polyethylene Wax and linear polyethylene LLDPE, after the current of the high-speed mixer suddenly increases, the material is discharged and cooled, and then crushed, added to a single-screw extruder to extrude at 140°C to 170°C, water-stretched strands are pelletized to obtain finished masterbatch products.

Embodiment 2

[0055] Weigh raw materials by weight: average particle size 200 nanometers subnanometer precipitated barium sulfate 75 kg, oxidized polyethylene wax 2 kg, aluminate 1.5 kg, modified EBS 0.5 kg, calcium stearate 0.5 kg, 1076 antioxidant 0.2 kg, low density polyethylene LDPE 20.3 kg.

[0056] Put the sub-nanometer precipitated barium sulfate into the high-speed mixer and heat it to 110°C, then add aluminate coupling agent for three minutes, then add modified EBS, calcium stearate, 1076 antioxidant, and finally add Oxidized polyethylene wax and low-density polyethylene LDPE, after the current of the high-speed mixer suddenly increases, the materials are discharged and cooled, and then crushed, put into a reciprocating extruder and extruded at 140°C to 170°C, water-stretched strands are pelletized to obtain the mother finished product.

Embodiment 3

[0058] Raw materials are taken by weight: 80 kg of sub-nanometer precipitated barium sulfate with an average particle size of 300 nanometers, 2 kg of EVA wax, 2 kg of titanate, 0.5 kg of oleic acid amide, 0.5 kg of barium stearate, 0.3 kg of 264 antioxidant, High-density polyethylene HDPE14.7 kg.

[0059] Put the sub-nanometer precipitated barium sulfate into the high-speed mixer and stir at high speed and heat it to 110°C, add titanate coupling agent for three minutes, then add oleic acid amide, barium stearate, 264 antioxidant, and finally add EVA wax and high-density polyethylene HDPE, after the current of the high-speed mixer suddenly increases, the material is cooled, then crushed, put into a twin-screw extruder and extruded at 110°C to 150°C, air-cooled and eagerly cut to obtain the finished masterbatch.

Abstract

The invention discloses a subnanometer enhanced and toughened transparent master batch and a preparation method thereof. The subnanometer enhanced and toughened transparent master batch comprises the following components in percentage by weight: 70-85 percent of subnanometer powder, 1-5 percent of dispersing agent, 0.3-1 percent of lubricating agent, 1-3 percent of coupling agent, 0.3-0.5 percent of thermal stabilizing agent, 0.1-0.5 percent of antioxidant and 10-25 percent of carrier resin. The preparation method comprises the following steps of: putting the subnanometer powder into a high speed mixer, selecting a high gear for stirring and heating, adding the coupling agent and treating for three minutes, then adding other raw materials, discharging and cooling after the raw materials are evenly stirred and mixed by the high speed mixer, then crushing, and extruding and pelleting through an extruding and pelleting device. The invention solves the problem that the mechanical performance of a plastic film is reduced after the common master batch is used in the prior art, in particular the problem that the light transmittance and the transparency are reduced; the mechanical performance of a film product is improved at the same time of reducing the cost; meanwhile, the invention achieves the purposes of enhancing and toughening and can be used in the fields of foods and medicines.

Description

technical field [0001] The invention relates to the field of inorganic powder modified high molecular polymers, in particular to a sub-nanometer reinforced toughened transparent masterbatch and a preparation method thereof. Background technique [0002] Plastic filled modified masterbatch has been put into the market since the early 1980s. Due to its low price and excellent product performance, it can improve some physical properties of plastic products and replace synthetic resins. The production process is simple and the investment is small. It has significant economic and social benefits. Therefore, plastic filling modified masterbatch is the fastest growing new industry in the plastics industry in recent years, and has become an important part of the plastics processing industry and one of the main additives for plastic products. [0003] my country has become the world's largest country in the production of plastic products, second only to the United States, with an an...
