preparation example Construction

[0036] A preparation method of HDPE antibacterial plastics, comprising the steps of:

[0037] 1) Premixing the antibacterial agent, ethylene bisstearamide and chitin to obtain a premixed material;

[0038] 2) Mix the premix obtained in step (1) with high-density polyethylene, polyethylene-2,6-naphthalate fiber, niobium oxide, and ethylene-propylene copolymer. After mixing evenly, add acetyl lemon Acetate tributyl ester, fully mix, obtain mixture;

[0039] 3) The mixture obtained in the above step (2) is granulated at a temperature of 180-200° C., and dried to obtain an antibacterial plastic.

Abstract

The invention discloses HDPE (high-density polyethylene) antibacterial plastic, which is mainly prepared from the following raw materials in parts by weight: 100 parts of HDPE, 4-8 parts of an antibacterial agent, 2-3 parts of ethylene bis-stearamide, 3-5 parts of a compatilizer and 1-2 parts of a plasticizer. The HDPE antibacterial plastic adopts 2-methoxy-N-acetoacetyl aniline and lithium carbonate as the antibacterial agent, and through reasonable compatibility, the best pathogenic microorganism killing effect and growth inhibiting effect can be achieved; a ethylene-propylene copolymer is used as the compatilizer, and after the compatilizer is combined with the HDPE, the mechanical strength of the HDPE can be further increased; the flexibility and easy-processing performance of the HDPEare improved by adding acetyl tributyl citrate; the antibacterial performance of the HDPE is further improved by adding chitosan.

Description

technical field [0001] The invention relates to a HDPE plastic, in particular to a HDPE antibacterial plastic and a preparation method thereof. Background technique [0002] At present, plastic products play a very important role in people's daily life and industrial and agricultural production. However, with the change of people's health concept, it is gradually realized that a large number of various healing bacteria that are harmful to human health will grow on the surface of plastic products. In order to effectively prevent and kill the bacteria attached to the plastic surface, people usually add antibacterial agents to the plastic to make antibacterial plastic, so that the plastic itself has antibacterial properties, which can kill or kill the bacteria that are stained on the plastic within a certain period of time. Inhibition, compared with conventional chemical and physical methods, the use of antibacterial plastics has a long sterilization time, which is economical ...
