Abstract

The invention relates to an LDPE (low-density polyethylene) fishing net filament, which comprises, by mass, 100 parts of LDPE; 0.3-0.5 part of UV-531; 0.3-0.5 part of DLTP; 0.3-0.5 part of zinc stearate; 0.5-1 part of barium stearate; 0.2-0.5 part of a light stabilizer; 10-15 parts of polybutadiene; 1-3 parts of carbon black; 5-10 parts of sodium hydrogen carbonate; 20-40 parts of butyl rubber; 20-40 parts of CPE; 2-3 parts of dibasic lead phosphite; and 25-45 parts of EVA. The product can tolerate a high temperature of 150-160DEG C and a low temperature of -30DEG C, has tensile strength of 10-20MPa, tensile elongation of 400-600%, and knot strength of 1.5-2MPa. Being light-fast and wear resistant, the product can be widely produced and be used for replacing existing materials continuously.

Description

technical field [0001] The application belongs to the field of plastic materials, in particular to an LDPE fishing net thread. Background technique [0002] Low-density polyethylene is a kind of plastic material, which is suitable for various molding processes of thermoplastic molding processing, and has good molding processability. LDPE is mainly used as film products, and also used in injection molding products, medical appliances, pharmaceutical and food packaging materials, blow molding hollow molding products, etc.; at the end of 1984, the United Carbon Company at that time introduced the production of hexene copolymerized LLDPE, followed by It was followed by companies such as Exxon and Mobil. Dow Chemical almost entirely uses octene as a comonomer in its low-pressure solution process, and Canadian NOVA also mostly uses octene in its medium-pressure solution process. Octene-copolymerized LLDPE resins have slightly better strength, tear resistance and processability, ...
