Embodiment 1
[0024] Formula: A special weeding film for fruit trees, made of the following raw materials in mass percentage: 80% linear low-density polyethylene; 4% low-density polyethylene; 6% aging-resistant masterbatch; 10% light-blocking black masterbatch. The anti-aging masterbatch is made by mixing and granulating the raw materials in the following weight ratio: 13 parts of hindered amine light stabilizer, 6.5 parts of composite antioxidant, and 6.5 parts of benzotriazole ultraviolet absorber.
[0025]Preparation process: It specifically includes the following steps. According to the above mass percentage, first add linear low-density polyethylene resin into the mixer, then add low-density polyethylene resin, then add aging-resistant masterbatch and light-blocking black masterbatch, stir and mix thoroughly Uniform; Siemens PLC terminal software is used to input the control temperature of the temperature controller, the length sensor to control the width, and the tensile tester to cont...
