Problems solved by technology

Due to the long-term immersion of waste fishing nets in water, the molecular chains have been degraded and broken to varying degrees due to the effects of external sunlight, salt, microorganisms, etc. When the relative molecular weight is reduced to below 10,000, PA6 will lose its basic use as an engineering plastic. value
In addition, due to the special environment used in water, a large am

Example Embodiment

[0027] Example 1

[0028] The recovered waste fishing nets are added to a high-speed crusher to be broken into pieces with a diameter of less than 10mm, and then poured into a large drum washing machine to wash off the sediment and centrifuged to dry, and then use a hopper oven to dry it to a moisture content of 0.2% ( Weight percentage).

[0029] Combine 98Kg of the above-mentioned dried waste fishing net fragments with 0.5Kg dioxazoline, 0.5Kg hindered phenol stabilizer: antioxidant 1098 (Yabao), 0.5Kg phosphite stabilizer: antioxidant 168 (Yabao) ) And 0.5Kg of magnesium stearate were mixed in a high-speed mixer for 2 minutes at high speed, and then added from the first feeder (main feeder) to a twin-screw extruder with an 800 mesh metal filter on the die. The temperature of the machine from the feed section to the die head is: 245°C, 245°C, 245°C, 235°C, 230°C, 220°C, 220°C, 210°C, the temperature of the die head is 235°C, and it is water cooled after extrusion , Cut into pel...

[0030] Example 2

[0031] After processing the recovered waste fishing nets to the requirements according to the treatment method in Example 1, 98Kg of the above-mentioned dried waste fishing net fragments, 0.5Kg epoxy styrene-acrylate oligomers, 0.5Kg hindered phenols and hindered phenols are stabilized Agent: Antioxidant 1098 (Albeo), 0.5Kg phosphite stabilizer: Antioxidant 168 (Albeo) and 0.5Kg polyester lubricant AC540 (Honeywell) are mixed at high speed in a high-speed mixer for 2 minutes Then, from the first feeder (main feed) into the twin-screw extruder with 800 mesh metal filter on the die, the temperature of the twin-screw extruder from the feed section to the die is 245℃, 245°C, 245°C, 235°C, 230°C, 220°C, 220°C, 210°C, the temperature of the die head is 235°C, after extrusion, it is water-cooled, pelletized, and packaged to obtain PA6 slices.

Example Embodiment

[0032] Example 3

[0033] After processing the recovered waste fishing nets to the requirements according to the treatment method in Example 1, 95Kg of the above-mentioned dried waste fishing net fragments and 0.5Kg dioxazoline, 0.5Kg epoxy styrene-acrylate oligomer, 1.5 Kg hindered phenol stabilizer: antioxidant 1098 (Yabao), 1.0Kg phosphite stabilizer: antioxidant 168 (Yabao), 0.5KG cuprous iodide and 0.5Kg magnesium stearate, 0.5Kg After the polyester lubricant AC540 (Honeywell) is mixed in a high-speed mixer for 2 minutes at high speed, it is added from the first feeder (main feeder) to a twin-screw extruder with an 800 mesh metal filter on the die. The temperature of the screw extruder from the feed section to the die head is: 245°C, 245°C, 245°C, 235°C, 230°C, 220°C, 220°C, 210°C, and the die temperature is 235°C. After water cooling, dicing, and packaging, PA6 slices are made.

Abstract

The invention discloses a nylon 6 slice prepared by using a waste fishing net. A raw material of the nylon 6 slice comprises the following components in percentage by weight: 95 to 98 percent of the waste fishing net, 0.5 to 1.0 percent of chain extender, 1.0 to 3.0 percent of compound heat stabilizer and 0.5 to 1.0 percent of lubricant. The nylon 6 slice has mechanical properties and mobile processing performance equivalent to that of a PA6 fresh material slice, has a light color and fewer impurities, can partially or completely replace a nylon 6 fresh material slice to be used for spinning or modifying engineering plastics and other raw materials, reduces environmental pollutions, realizes the cyclic utilization of resources, and has great social effects and economic benefits.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a nylon 6 slice prepared by using waste fishing nets and a preparation method thereof. Background technique [0002] my country has a long coastline and many inland rivers and lakes. Fishing and aquaculture are very common. A large number of fishing nets are used every year, and many waste and rotten fishing nets are discarded. Fishing nets are basically made of nylon 6 after spinning. If discarded at will, they cannot be degraded in a short time, which brings great harm to the environment and aquatic animals and plants. [0003] Nylon 6 (referred to as PA6), which is polymerized from caprolactam, is the final product of the petroleum industry, and it is also a type of basic resin with the largest output, the most varieties, the widest range of uses, and excellent comprehensive performance among the five general-purpose engineering plastics. The molecular weight of nylon 6 for e...
