Problems solved by technology

[0005] Because there is no special resin for photovoltaic barrels on the market at present, a certain hollow resin on the market is the most used product in the field of photovoltaic barrels, but the processing performance of this product cannot meet the requirements of hollow products with irregular shapes such as photovoltaic barrels, let alone light floating barrels. Rapid prototyping, uniform wall thickness requirements
Some manufacturers use a variety of resins to mix, the product uniformity is poor, the strength is insufficient, and the performance is even worse.

Embodiment approach

[0048] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0049] Refer to attached Figure 1-7 , the twin-screw extruder used in the present invention is equipped with three groups of kneading blocks in the metering section of the screw, and the three groups of kneading blocks are successively a group of 90° kneading blocks 3 and a group of 60° kneading blocks from the feed end to the discharge end Block 4 and a group of 45° kneading block 5; the included angle of the vertical line between adjacent kneading sheets 1 in 90° kneading block 3 is 90°, and the clip of the vertical line between adjacent kneading sheets 1 in 60° kneading block 4 The angle is 60°, and the included angle of the vertical line between adjacent kneading pieces 1 in the 45° kneading block 5 is 45°. The kneading blocks are arranged in sequence to form a kneading zone. During the extrusion process, the composition is easy to shear and disper...

Abstract

The invention belongs to the technical field of high polymer materials, and particularly relates to a high-density polyethylene resin composition for a floating photovoltaic barrel and a preparation method of the high-density polyethylene resin composition. The composition is prepared from the following components in parts by mass: 100 parts of high-density polyethylene; 0.1-0.2 part of a light stabilizer; 0.1-0.15 part of an antioxidant; 0.05-0.3 part of zinc oxide. In the high-density polyethylene resin, the mass percentage content of lamellar crystals with the thickness smaller than 6.1 nm is 2.0-4.0%, the mass percentage content of lamellar crystals with the thickness larger than 16.6 nm is 42.0-59.0%, and the mass ratio of the lamellar crystals with the thickness larger than 16.6 nm to the lamellar crystals with the thickness smaller than 6.1 nm is 16-20: 1. The high-density polyethylene resin composition has good weather resistance, rigidity and toughness and processability, meanwhile, zinc oxide and DDHI are added, the light aging resistance of the material is improved, the performance and the service life of a photovoltaic barrel are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a high-density polyethylene resin composition for a floating photovoltaic bucket and a preparation method thereof. Background technique [0002] Floating photovoltaic power station on water is a facility that uses water bases to float photovoltaic modules on the water surface for power generation. It is mainly composed of floating barrels, brackets, and solar panels. Coal mining subsidence areas and sewage treatment plants can be installed as long as there is a certain amount of water. The feature is that it does not occupy land resources, and the water body has a cooling effect on the photovoltaic modules, which can suppress the rise in the surface temperature of the modules, thereby obtaining higher power generation. In addition, covering the water surface with solar panels can also reduce the evaporation of the water surface, inhibit the reproduction of ...
