At the same time, an anti-blocking agent is added to this masterbatch to avoid adhesion between masterbatches. Specific embodiments

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Example 1:

[0021] A functional masterbatch for antistatic weather-resistant PE film anti-blocking, comprising the following components in mass percentages: carrier resin 42% - 54%, filler 18% - 30%, antioxidant 3% - 7%, antistatic agent 2% - 4.3%, anti-blocking agent 3% - 4.5%, dispersant 1.4% - 2.7%, plasticizer 3% - 6%, lubricant 1.7% - 3.4%, crosslinking agent 4% - 6%, antibacterial agent 3% - 4.3%;

[0022] Specifically, the filler is at least one of iron oxide red, calcium carbonate and quartz sand. Iron oxide red can endow the masterbatch products with color and also play a certain covering role, thereby improving the aesthetics and practicality of the products. Iron oxide red also has certain thermal stability and can maintain a stable color in high-temperature environments;

[0023] Calcium carbonate is widely used in filling polyethylene resins. Adding calcium carbonate plays a certain role in improving the properties of plastic products and expanding their application scope. In plastic processing, they can reduce the resin shrinkage rate, improve the flow state, control the viscosity, and also play the following roles:

[0024] (1) Improve the dimensional stability of plastic products;

[0025] (2) Improve the hardness and rigidity of plastic products;

[0031] Quartz sand is quartz particles obtained by crushing and processing quartz stone. Quartz stone is a non-metallic mineral, a hard, wear-resistant, and chemically stable silicate mineral. Adding an appropriate amount of quartz sand filler to the PE film masterbatch can improve the strength, hardness, wear resistance, and weather resistance of the made plastic film, etc. At the same time, it can also increase the color sense and decorative property of the products. In addition, the quartz sand filler can also reduce the cost of the products because its price is relatively low and the source is relatively abundant;

[0039] Polyvinylpyrrolidone is a non - ionic surfactant with good leveling property and dispersion stability, which can improve the processability and stability of the PE film masterbatch, and at the same time reduce the phenomena of sticking and agglomeration;

[0040] Polyurethane propylene oxide and polyurethane acrylate have good fluidity and compatibility, which can improve the processability and stability of the PE film masterbatch, and at the same time reduce the phenomena of sticking and agglomeration;

[0041] Specifically, the plasticizer is at least one of octyl butyl aldehyde and polyvinyl chloride resin. Octyl butyl aldehyde is an excellent plasticizer with high cold resistance and good compatibility, and is suitable for manufacturing soft - quality PE film masterbatch;

[0042] Polyvinyl chloride resin reduces the content of part of PE in the PE film masterbatch through blending or modification, etc., so as to achieve the purpose of plasticization;

[0043] Specifically, the lubricant is at least one of polystyrene, polyoxyethylene - based ether ester, and dimethylsilanol. Polystyrene is a high - molecular - weight polymer with good lubricating properties and good compatibility, and is suitable for the production of PE film masterbatch;

[0044] Polyoxyethylene - based ether ester is a high - molecular - weight polymer with good lubricating properties and high heat resistance, and is suitable for the production of PE film masterbatch;

[0046] Specifically, the cross - linker is at least one of sodium oxide, ammonium cerium sulfate, and calcium dihydrogen phosphate. Sodium oxide can break the double bonds between PE molecules, cross - link the polymer into a network structure, thereby enhancing its mechanical properties such as strength, hardness, stiffness, and toughness;

[0047] Ammonium cerium(IV) sulfate and calcium dihydrogen phosphate can act as catalysts in the cross-linking reaction, accelerating or slowing down the cross-linking reaction rate, and can affect the structure and properties of the cross-linked product by adjusting their types and dosages;

[0048] Specifically, the antibacterial agent is at least one of nanoscale silver particles and titanium dioxide. The nanoscale silver particles have good antibacterial, antivirus, and antifungal properties and are harmless to the human body;
