Embodiment 1
[0021] The invention provides a production method of fishing rod film. Firstly, polypropylene with an isotacticity of more than 96% is selected as the main raw material, and an anti-blocking agent with a mass fraction of 0.5-3%, 0.5-3% The slip agent and 0.5-3% high-temperature-resistant additives are mixed evenly; the mixed raw materials are added to the extruder, and a three-layer stretched film is formed after co-extrusion and stretching;
[0022] The above-mentioned three-layer stretched film is used as the base film, heat-conducting oil is used as the medium, and the surface of the metal roller is used for heating. Two heating zones are set, and four heating rollers are used for heating in the first zone. The heating temperature range The temperature range is 90°C-110°C, and the second zone is also heated by four heating rollers. The heating temperature range is 110°C-130°C; the base film is stretched after heating, and the stretch ratio of the first zone is 1.0-1.5 , the...
Embodiment 2
[0028] The main difference between this example and Example 1 is that when preparing the base film, a matting masterbatch with a mass fraction of 0.4-2% is added to the raw materials and mixed evenly with other raw materials, and then added to the extruder through co-extrusion, After stretching, a three-layer stretched film is formed. The matting masterbatch is added to the upper surface layer or the lower surface layer of the base film to change the glossiness of the base film to form matte or semi-matte, and to produce fishing rod products with excellent texture and feel.
[0029] After testing, the fishing rod film produced by the above method can meet all the performance indicators in the fishing rod production process. The theory is combined with the experiment and finally the data indicators are tested in the fishing rod products. All the process indicators come from the fishing rod products. Performance testing.
