Embodiment 1
[0027] The linear low-density polyethylene (LLDPE, 7047) is used as raw material, and industrial pigment (reduced bright green FFB) is added, and the added amount accounts for 0.8% of the linear low-density polyethylene (LLDPE) according to the weight percentage.
[0028] The processing steps are as follows:
[0029] The raw materials are stirred, and the raw materials are respectively added into a high-speed mixer, stirred and mixed, and the stirring speed is 5000 rpm, and the time is 50 minutes.
[0030] High temperature and high pressure injection molding. Put the mixed raw materials into a high-temperature and high-pressure injection molding machine, and perform injection molding at a temperature of 180° C. and a pressure of 2 MPa.
[0031] Injection molding. The injection molding material is added to the mold cast according to the shape of the product, and is shaped by the mold.
[0032] Composite, bonding non-woven fabric and heat-resistant non-slip mesh on the bottom...
