[0098] Embodiment six:

[0099] This embodiment provides a method for preparing an anti-aging matte masterbatch for PE artificial turf yarn on the basis of the first embodiment, and the steps are as follows:

[0100] The first step is to prepare the required raw materials by weight and introduce them into a mixing device for concentration;

[0101] In the second step, auxiliary agents and water are added into the mixing device, and the raw materials are mixed by the mixing device;

[0102] The third step is to dry the mixed slurry;

[0103] The fourth step is to stretch the dried slurry and cut it to obtain a masterbatch product;

[0104] In summary, after comparing the data of Embodiment 2, Embodiment 3, Embodiment 4 and Embodiment 5, Embodiment 4 is the best embodiment of the present invention;

[0105] Furthermore, polyethylene glycol is a high molecular weight polymer and has good compatibility with many organic components. It has excellent lubricity, moisture retention, dispersibility, and adhesion. Combined with the stable performance of carboxymethyl cellulose, it can effectively adjust the texture of the masterbatch.

[0106] Furthermore, potassium sorbate, also known as potassium 2,4-hexadienoate, is the potassium salt of sorbic acid, with the molecular formula C6H7O2K, colorless or white flaky crystals or crystalline powder, odorless or slightly odorous, easy to absorb moisture, oxidized and decomposed to change color when exposed to the air for a long time, and can protect artificial masterbatch from microbial contamination;

[0107] Furthermore, polyvinyl alcohol is an organic compound with the chemical formula [C2H4O]n, and its appearance is a white flake, flocculent or powdery solid, which has good fluidity and stability, and can be combined with polyacrylate to reduce the surface tension of the masterbatch, improve its fluidity, and reduce agglomeration;

[0108] Furthermore, calcium carbonate is an inorganic compound with the chemical formula CaCO3. It is widely used in filling polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), acrylonitrile butadiene-styrene copolymer (ABS) and other resins. Adding calcium carbonate has a certain effect on improving certain properties to expand its application range. In masterbatch processing, they can reduce resin shrinkage, improve rheology, control viscosity, and also play the following roles:

[0109] (1) Improve the dimensional stability of plastic products;

[0110] (2) Improve the hardness and rigidity of plastic products;

[0111] (3) Improve plastic processing performance;

[0112] (4) Improve the heat resistance of plastic products;

[0113] (5) Improve the light diffusion property of plastics;

[0114] In summary, the anti-aging and matting masterbatch for PE artificial turf yarn can effectively improve the physical properties of the masterbatch through the mutual cooperation of PE resin, pigment, reinforcing agent, lubricant, filler, antioxidant, anti-aging agent and matting agent, so that it will not produce obvious discoloration due to time or environmental factors during application, thereby ensuring the beauty of subsequent finished products;
