Abstract

The invention belongs to the field of antibacterial materials and products thereof, and relates to an antibacterial mildew-proof polyethylene composition and foamed beads, a preparation method thereof, and a molded body. The antibacterial and mildewproof polyethylene composition contains polyethylene base resin, a guanidine salt composite antibacterial agent, a mildewproof agent and an auxiliary agent, wherein the auxiliary agent contains a foam nucleating agent and an optional antioxidant; based on 100 parts by weight of the polyethylene base resin, the content of the guanidine salt compositeantibacterial agent is 0.05-2.0 parts by weight, the content of the mildew preventive is 0.01-5.0 parts by weight, the content of the foam nucleating agent is 0.01-10 parts by weight, and the contentof the antioxidant is 0-10 parts by weight. The antibacterial and mildewproof polyethylene composition is good in antibacterial and mildewproof effects, the water resistance is also improved, the foamed beads prepared from the antibacterial and mildewproof polyethylene composition have impact resistance and low molding temperature, and the obtained molded product is excellent in antibacterial andmildewproof performance and high in compression strength.

Description

technical field

[0001] The invention belongs to the field of antibacterial materials and products thereof, and more specifically relates to the preparation of an antibacterial and antimold polyethylene composition, an antibacterial and antimold polyethylene foam beads, and an antibacterial and antimold polyethylene foam beads method, and an antibacterial and antifungal polyethylene foamed bead molded body. Background technique

[0002] Today, large-scale industrial production of polyethylene foam products usually uses extrusion foaming technology. Compared with the traditional extrusion foaming method, when preparing polyethylene foam products by the reactor immersion method, there is no high-shear screw extrusion of the extrusion method acting on the polyethylene melt, and the entanglement of the polymer chains ensures that the melt has enough strength. During the cell growth process, the biaxial stretching of the cell wall is not easy to break; at the same time, the PE c...
