Embodiment 1

[0042] A preparation method of a high-performance colored antistatic radiation cross-linked polyethylene foam material, comprising the following steps: 91.5% of low-density polyethylene (LDPE), 2% of foaming agent, 5% of toughening agent, 1% antistatic agent, 0.2% coupling agent, 0.1% antioxidant, 0.1% lubricant, 0.1% coloring agent, mixed in a mixer at low speed for 240 seconds and then at high speed for 320 seconds, after a single melting temperature of 110-125 ° C The screw extruder extrudes into flakes, and the thickness of the flakes can be adjusted by the abrasive die and the pulling speed; the temperature of each section is: 105°C in the first zone, 110°C in the second zone, 120°C in the third zone, 110°C in the fourth zone, and 110°C in the fifth zone. Zone 110°C, zone six 120°C, die head 115°C, residence time of the mixture in the screw is 120 seconds. After being rolled into a sheet, it is then irradiated. The irradiation process conditions are: 2.1 Mev energy, 8 irr...

Embodiment 2

[0044] A preparation method of a high-performance color antistatic radiation cross-linked polyethylene foam material, comprising the following steps: 84.75% of low-density polyethylene (LDPE), 5% of foaming agent, 5% of toughening agent, 0.5% of coupling agent, 0.3% of antioxidant, 0.3% of lubricant, 0.15% of colorant, mixed in the mixer at low speed for 240 seconds and high speed for 320 seconds, and extruded through a single-screw extruder with a melting temperature of 110-125°C Formed into sheets, the thickness of the sheets can be adjusted through the mold die and traction speed; the temperature of each section is: 105 °C in the first area, 110 °C in the second area, 120 °C in the third area, 110 °C in the fourth area, 110 °C in the fifth area, and 110 °C in the sixth area 120°C, die head 115°C, residence time of the mixture in the screw is 120 seconds. After being rolled into a sheet, it is then irradiated. The irradiation process conditions are: 2.1 Mev energy, 8 irradia...

Embodiment 3

[0046] A preparation method of a high-performance colored antistatic radiation cross-linked polyethylene foam material, comprising the following steps: 84.45% low-density polyethylene (LDPE), 5% foaming agent, 5% toughening agent, 4% antistatic agent, 0.8% coupling agent, 0.3% antioxidant, 0.3% lubricant, 0.15% coloring agent, mixed in a mixer at low speed for 240 seconds and then at high speed for 320 seconds, after a single melting temperature of 110-125 ° C The screw extruder extrudes into flakes, and the thickness of the flakes can be adjusted by the abrasive die and the pulling speed. The rest of the preparation methods are the same as in Example 1, and will not be repeated here.

Abstract

The invention discloses a colored high-performance and anti-static radiation cross-linked polyethylene foam material and a preparation method thereof. Low-density polyethylene and a foaming agent are adopted, a toughening agent, an antistatic agent, a coupling agent, an antioxidant, a lubricating agent and a coloring agent are added for process optimizing treatment, a product has excellent impact resistance, excellent anti-static performance and a dazzling surface vision effect, changes the condition that most anti-static radiation cross-linked polyethylene foam cotton is black, fills up the blank, can completely meet the demand of the current market for the anti-static cross-linked polyethylene foam material, improves the market competitiveness, is important improvement of common anti-static foaming polyethylene materials and overcomes the defects of high cost, difficulty in process and low mechanical property of conventional anti-static polyethylene foam cotton.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-performance colored antistatic radiation cross-linked polyethylene foam material and a preparation method thereof. The material can be widely used in consumer electronics, decoration, packaging and other fields. Background technique [0002] Cross-linked polyethylene foam material is a kind of polyethylene as the main raw material, together with several other auxiliary materials that do not contain any harmful substances. The cross-linking produced by the substance changes the original structure of the base material and forms a network-like independent closed-cell cell structure. The high-tech high-grade closed-cell foam material produced has outstanding impact resistance, creep resistance and good dimensional stability. Thermal insulation, low water absorption, widely used in construction, electronic equipment, packaging, sports equipment, medical care and oth...
