Problems solved by technology

However, with the advancement of fishing rod production technology, high-carbon fiber materials are gradually adopted in the production of fishing rods. At the same time, cellophane also shows low tensile strength, easy moisture absorption, high specific gravity, and cannot be recycled after production and use, causing environmental protection hazards.

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.

Abstract

The invention relates to a production method of a fishing rod film. The method comprises the following steps: selecting polypropylene of which the isotacticity is over 96 percent for serving as a major raw material, adding 0.5-3 percent by mass of anti-blocking agent, 0.5-3 percent by mass of slip agent and 0.5-3 percent by mass of high-temperature-resistant aid into the polypropylene raw material, and mixing uniformly; adding the mixed raw materials into an extruder, forming three layers of stretched films through co-extrusion and stretching, and performing eight segments of preheating, four segments of stretching, two segments of sizing and two segments of cooling in two areas. The fishing rod film can be prevented from being bonded during hot molding at the high temperature below 150 DEG C, does not contract transversely, is combined firmly on a cloth layer, does not contain air bubbles, is easy to peel after cooling and molding, can be applied to manufacturing of various products such as ball arms and ski sticks, and is wide in application.

Description

technical field [0001] The invention relates to the field of manufacturing technology of daily necessities, in particular to a production method of fishing rod film. Background technique [0002] Since the domestic research and development and production of fishing rods began in the 1990s, it has experienced a process of learning from foreign advanced technologies, self-digestion and improvement. Fishing rods generally use glass fiber base material or carbon fiber base material. Since fishing rods need to be wound and shaped during the heating and curing molding process, the existing setting material is cellophane. Cellophane has small thermal deformation, high temperature resistance, and easy Advantages such as stripping are used in batches in fishing rod production. However, with the advancement of fishing rod production technology, high-carbon fiber materials are gradually used in the production of fishing rods. At the same time, cellophane also shows low tensile strengt...
