Problems solved by technology

Among them, as a new type of inorganic antibacterial agent, nano-titanium dioxide silver-loaded antibacterial agent has the advantages of strong antibacterial ability, long time, wide antibacterial spectrum, and good biological safety. It is mainly used in surgical instruments, contraceptives, and bones. Antibacterial agents are used in medical fields such as prostheses, but are rarely used in general-purpose plastic products in the field of daily life. The required addition amount leads to a substantial increase in the cost of polypropylene composite materials, which do not have strong market competitiveness. It is necessary to reduce costs or improve its antibacterial efficiency and reduce usage to control the cost of composite materials; Second, due to the high surface energy of the added na

Abstract

The invention discloses a composite material comprising a low-cost high-efficiency broad-spectrum antibacterial polypropylene functional master batch and a preparation method thereof. The composite material is prepared from the following raw materials in parts by weight: 5-10 parts of antibacterial functional master batch, 48-93 parts of conventional polypropylene, 0-40 parts of inorganic filler, 8-20 parts of elastomer, 0.1-1 part of antioxidant and 0-3 parts of other aids. The technical scheme of the invention reduces the influence of heavy addition of the antibacterial agent on other properties of the material on the premise of lowering the material cost. The prepared antibacterial polypropylene composite material has the characteristics of high efficiency, broad antibacterial spectrum, favorable mechanical properties and the like.

Description

technical field [0001] The invention relates to a functional polypropylene material and a preparation method thereof, in particular to a low-cost, high-efficiency, broad-spectrum antibacterial polypropylene functional masterbatch and a preparation method thereof, belonging to the technical field of polypropylene. Background technique [0002] Polypropylene plastic is widely used in automotive interior and exterior decoration, home appliances, PC and other products because of its wide source of raw materials, cheap price, excellent heat resistance and easy molding processing, and has become the fastest growing industry.
