Abstract

A preparation method of a low-surface-tension fishing net is disclosed. The method includes steps of (1) after acrylonitrile, ethylcyclopentenolone, dodecyl methacrylate, and glycidyl methacrylate areuniformly mixed, adding aluminum borate, alumina fibers and an initiator into the mixture, heating the mixture to 65-70 DEG C after the mixture is fully mixed, and maintaining the temperature for 2-3h to obtain a polymerization emulsion; (2) mixing the polymerization emulsion, poplar powder, glycerin and a dispersing agent, then adding the mixture into a high-speed mixer, fully mixing the mixture, then putting the mixture into a drying oven, and drying to obtain an additive; and (3) adding polyethylene resin, the additive and an antioxidant into a feeding hopper of a single-screw extruder, performing extrusion, drawing and cooling to obtain a fishing net wire, and weaving the fishing net wire to obtain the fishing net. The fishing net has excellent mechanical properties, and has low surface tension in water and a high sinking speed, thus effectively increasing the fishing efficiency.

Description

technical field [0001] The invention belongs to the technical field of fishing net preparation, and in particular relates to a method for preparing a low surface tension fishing net. Background technique [0002] The ancients used coarse cloth and hemp as raw materials to make fishing nets by bundling. Although this fishing net is perishable and has poor toughness, its fishing efficiency has been greatly improved. With the development of fishery, the objects of fishing and hunting are not only fish, but also the fishing tools are advancing with the times. Modern fishing nets are mainly processed with polyethylene, nylon and other raw materials. It has a longer service life and higher fishing efficiency. During the sinking process of the fishing net in the water, because the surface area of ​​the fishing net is large, the buoyancy force received as a whole is relatively large, and the descending speed of the fishing net is relatively slow, which seriously affects the fishi...
