Abstract

Sterilizing polyester resin includes the following components, by weight, 95 parts of PBT, 5 parts of PET and 0.2-0.4 parts of a composite antibacterial agent which is composed of zeolite powder, nano titanium dioxide, nano silver oxide and polyhexamethylene guanidine phosphate. The antibacterial ABS resin has the following advantages: 1) with the zeolite powder as the carrier for supporting the nano titanium dioxide and the like, the nano titanium dioxide is free of caking, which reduces the effect of photocatalysis; and 2) a titanium dioxide photocatalysis technology and silver ion sterilization are combined for inorganic sterilization, and as well as the polyhexamethylene guanidine phosphate which has strong sterilization effect, so that the sterilization effect is greatly improved due to combination of both inorganic and organic sterilization.

Description

technical field [0001] The invention relates to a bactericidal polyester resin. Background technique [0002] In our lives, some harmful bacteria exist and multiply on the surface of plastic resin products. The parts of household appliances that are in frequent contact with the human body and objects, such as refrigerator shelves, plastic cup lids, door handles, mice, keyboards, The surface of the mobile phone casing and so on is a place where bacteria multiply. [0003] The hands of the human body are in contact with plastic products and are contaminated with bacteria, which can lead to various diseases. As users' awareness of health continues to increase, there is a demand for "antibacterial and sterilizing" plastic parts of household appliances that are frequently touched in daily life. [0004] The development and research of antibacterial plastics began in the 1980s, and great progress has been made with the technology of Japan and Western developed countries, and the...
