Description

Technical Field

[0001] This application belongs to the field of fishing gear technology, and in particular relates to a transparent, lightweight hollow tube for the tail of an electronic fish float, its preparation method and application. Background Technology

[0002] Fishing floats are crucial tools in fishing. Anglers use the sinking of the float to receive information about fish biting the bait and determine when to set the hook. Electronic fishing floats are a type of float specifically referring to floats with light-emitting tips. They are mainly composed of a hollow tube, optical fiber, and float beads. The optical fiber is housed inside the hollow tube, and the float beads are coated on its surface. The hollow tube acts as a carrier for the optical fiber and float beads, protecting the fiber and transmitting light. Therefore, its performance, such as mechanical properties and transparency, is very important and affects the overall performance of the float tip.

[0003] Currently, the hollow tubes used for electronic float tips on the market are mainly made of fiberglass tubes, which have the following problems: 1. The material has a high density and is heavy, which is not conducive to the float tip tilting and turning quickly in the water, thereby reducing the signal sensitivity and affecting the angler's judgment; 2. The toughness is too poor. The main component of fiberglass tube is inorganic material, which is very brittle. Therefore, the high brittleness and poor toughness cause the float tip to break frequently when subjected to bending external force, resulting in damage to the entire float product.

[0004] Therefore, it is urgent to find a hollow tube for the tip of a fishing float that is lightweight, has high compressive strength, and good toughness. Summary of the Invention

However, the glass fiber content was low and the adhesion between the resin and the glass fiber was weak, resulting in low mechanical strength and making it impossible to prepare regular hollow tubes.

[0038] Comparative Example 2 Neopentyl fumarate resin, 2,5-dichlorostyrene, benzoyl peroxide, and dodecyl phosphate were weighed and mixed in a weight ratio of 100:25:1:1 and stirred for 30 minutes.

However, the strength was too low and it was crushed during pultrusion, making it impossible to prepare regular hollow tubes.

[0039] Comparative Example 3 The maleic anhydride, ethylene adipate resin, methyl methacrylate, benzoyl peroxide, and dodecyl phosphate were weighed and mixed in a weight ratio of 100:30:1:1 and stirred for 30 minutes. After the resin mixture was defoamed, it was poured into an impregnation tank.
