Problems solved by technology

The crystal water decomposed by halloysite nanotubes at high temperature can dilute combustible gas and inhibit the spread of combustion. However, when only halloysite is added to the polymer, the flame retardant effect is not obvious, so halloysite is generally used as a synergistic retarder. fuel

Abstract

The invention relates to a flame-retardant antibacterial compound containing halloysite, and a preparation method thereof. The flame-retardant antibacterial compound containing halloysite nanotubes ishalloysite nanotubes loaded with elemental copper and phosphate. The flame-retardant antibacterial compound containing halloysite nanotubes can be uniformly dispersed in a polymer matrix, so the polymer has the antibacterial property and the flame-retardant property, the mechanical properties of the polymer are not obviously influence, and the application range of the polymer is expanded.

Description

technical field [0001] The invention belongs to the field of additives for polymer composite materials, and in particular relates to a halloysite-containing flame-retardant and antibacterial compound and a preparation method thereof. Background technique [0002] In recent years, the polymer industry has developed rapidly, and plastics have been used in various fields of life. With the continuous improvement of people's living environment and level, people hope that commonly used plastics have both flame retardant and antibacterial properties. Therefore, on the basis of flame retardancy, endowing plastics with antibacterial properties is the development trend of plastics today. Multifunctional plastic products that are both flame retardant and antibacterial have great application value in emerging fields such as aviation. [0003] The traditional antibacterial and flame retardant modification methods are to add antibacterial agents and flame retardants to the polymer matri...
