Problems solved by technology

Among them, monofilament refers to a single filament with a diameter of 0.1-1.5 mm. Fishing nets woven with monofilaments have better transparency in water and higher fishing efficiency, but the strength of monofilament fishing nets is low. A series of treatments are required before use. In the prior art, a special fixing agent for monofilament fishing nets is mixed with a softener to make a treatment solution, and then the fishing net is placed in the treatment solution and soaked for a few seconds. Lower cured nylon mesh nodules
However, currently commercially available adhesives or other adhesive components cannot bond nylon nodules to achieve the specified fastness, especially the waterproofness of the adhesive is poor, and it will swell in water, reducing the transparency of the monofilament fishing net. thus reducing the quality of monofilament fishing nets

Abstract

The invention discloses a method for preparing a binder for waterproof monofilament fishing nets. Add N-octyldiaminoethylglycine hydrochloride, mix and stir evenly; (3) After adding the additive solution to the mixture prepared in step (2), slowly add a strong oxidant solution to it, and reduce the temperature of the reactant to After rising to 60-70°C, heat preservation treatment for 15-30 minutes, filter to obtain the filter residue, clean the filter residue with deionized water, and obtain the required binder. The adhesive for monofilament fishing net provided by the present invention has low raw material price, simple manufacturing method, and the prepared adhesive has strong cohesive force and can be cured at room temperature by itself, so that the net knot can achieve sufficient strength, and Strong water resistance, will not swell in water, will not affect the transparency of monofilament fishing nets, and have no color difference in water.

Description

technical field [0001] The invention belongs to the field of fishing net preparation, and in particular relates to a method for preparing a binder for waterproof monofilament fishing nets. Background technique [0002] More than 99% of fishing nets are made of synthetic fibers, mainly monofilament, multifilament or multi-filament of nylon 6 or modified nylon, and fibers such as polyethylene, polyester, and polyvinylidene chloride can also be used. Among them, monofilament refers to a single filament with a diameter of 0.1-1.5 mm. Fishing nets woven with monofilaments have better transparency in water and higher fishing efficiency, but the strength of monofilament fishing nets is low. A series of treatments are required before use. In the prior art, a special fixing agent for monofilament fishing nets is mixed with a softener to make a treatment solution, and then the fishing net is placed in the treatment solution and soaked for a few seconds. Under cured nylon mesh nodules...
