Embodiment 1

[0040] Weigh 100 parts of PA6 of M2500, 15 parts of HA, 0.02 parts of anti-1098, 0.02 parts of anti-168, 0.05 parts of lubricant TR044, mix in a high-speed mixer for 5 minutes, and extrude the uniformly mixed material in a twin-screw extruder out of granulation.

[0041] The temperature of the extruder is set to: 200°C in zone I, 220°C in zone II, 235°C in zone III, 240°C in zone IV, 235°C in zone V, 235°C in zone VI, and 240°C at the head. After the material is extruded, it is cooled by water, Cut into pellets, dry the pellets at 100°C for 3 hours, make a sample strip by an injection molding machine, and place it at a constant temperature of 25°C for 16 hours before testing. The performance test results are shown in Table 2.

Embodiment 2

[0043] Weigh 100 parts of M2500 PA6, 30 parts of HA, 0.02 parts of anti-1098, 0.02 parts of anti-168, 0.05 parts of lubricant TR044, mix in a high-speed mixer for 5 minutes, and extrude the uniformly mixed material in a twin-screw extruder out of granulation.

[0044] The temperature of the extruder is set to: 200°C in zone I, 220°C in zone II, 235°C in zone III, 240°C in zone IV, 235°C in zone V, 235°C in zone VI, and 240°C at the head. After the material is extruded, it is cooled by water, Cut into pellets, dry the pellets at 100°C for 3 hours, make a sample strip by an injection molding machine, and place it at a constant temperature of 25°C for 16 hours before testing. The performance test results are shown in Table 2.

Embodiment 3

[0052] Weigh 100 parts of S2040 PP, 20 parts of HA, 0.03 part of anti-1098, 0.03 part of anti-168, 0.03 part of 36# white oil, mix in a high-speed mixer for 5 minutes, and put the uniformly mixed material in a twin-screw extruder Extrusion granulation.

[0053] The extruder temperature setting is: 180°C in zone I, 190°C in zone II, 195°C in zone III, 200°C in zone IV, 205°C in zone V, 210°C in zone VI, and 215°C at the head. After extrusion, the material is cooled by water, Cut into pellets, dry the pellets at 100°C for 3 hours, make a sample by an injection molding machine, and place it at a constant temperature of 25°C for 16 hours before testing. The performance test results are shown in Table 3.

Abstract

The invention belongs to the technical field of high polymer materials, and relates to modified plastics and a preparation method thereof. The modified plastics comprises, by weight, 100 parts of component manufactured plastics and 1-100 parts of humic acid materials. Compared with the prior art, the modified plastics and the preparation method thereof have the advantages that humic acid is wide in source and low in cost, the plastics modified with the humic acid materials, and thus cost can be reduced; the humic acid has the advantages of being green, environment friendly and the like, and parts of the performances, such as bending performance and heat-resistant performance, of the plastics are improved.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a modified plastic and a preparation method thereof. Background technique [0002] There are many methods of plastic modification, such as blending modification, filling modification, reinforcement modification, composite modification, surface modification and so on. There are also many substances used to modify plastics, such as organic substances: cellulose, plastics, rubber, etc.; inorganic substances: calcium carbonate, talcum powder, carbon black, titanium dioxide, mica, kaolin, white mud, silicic acid Salts, metal oxides, silica, glass beads, etc. Reports on such substances include WO2005IB50845, CN20041084708, US19840596795, and US19900590320. [0003] Humic acid is a type of natural organic substance produced and accumulated by animal and plant remains (mainly plant remains) through microbial decomposition and transformation, as well as a series of geochemical p...
