Abstract

The invention provides an anti-pressing and antibacterial polyamide composite material and a preparation method thereof, and belongs to the field of engineering plastic modification. The anti-pressingand antibacterial polyamide composite material is prepared from the following raw materials in parts by mass: 100 parts of a resin substrate, 5-45 parts of diatomite, 0.1-0.5 part of a coupling agent, 0.05-0.5 part of an antioxidant, 0.05-0.5 part of a lubricant and 0.2-1 part of a heat stabilizer. Polyamide resin is modified through the diatomite, the prepared composite material has the characteristics of large mechanical strength and compressive strength, and meanwhile has the antibacterial and bacteriostatic effects, and traditional modified engineering plastic is endowed with certain functionality; and in addition, equipment and processes needed for preparation of the composite material are simple, and large-scale production can be directly conducted.

Description

technical field [0001] The invention belongs to the field of modification of engineering plastics, and relates to a compression-resistant and antibacterial polyamide composite material and a preparation method thereof. Background technique [0002] Polyamide is a common modified matrix resin for engineering plastics. It has the characteristics of wear resistance and high strength, and is widely used in the fields represented by vehicles and electric tools. However, with the emergence of some emerging products, some functional requirements are put forward for materials, which cannot be met by traditional modification methods. [0003] Diatomite is a mineral with natural antibacterial and antibacterial effects. It also has a microporous structure. During the modification process, macromolecules in the molten state can penetrate through it to form an interconnected network, which can make the composite material have excellent performance. Contents of the invention [0004] T...
