Problems solved by technology

Therefore, antibacterial nylon was born. However, ordinary antibacterial nylon products mostly achieve antibacterial effect by adding antibacterial agents to kill surface bacteria. Most antibacterial nylon products still have deficiencies in broad-spectrum, bactericidal efficiency, and degradability. Use and environmental protection have brought many problems

Abstract

The invention discloses an easily-degradable anti-microbial nylon composite material and a preparation method thereof. The preparation method comprises the steps of with nylon resin, aluminum titanate fiber, ethyl acetate amide and hydroxystearic acid as the main components, adding N-ethylene amide distearate, resorcinol monobenzoate, octadecanoyl tributyl citrate, germanium powder, spinel powder, cetearyl alcohol, butylhydroxyanisole, zinc ricinoleate, dibutyltin diacetate, barium laurate soap, a silane coupling agent, an antioxidant and an antioxidant, and carrying out processes of stirring grinding, high-temperature calcination, ultrasonic dispersion, high-temperature smelting, extrusion molding and the like, so as to obtain the nylon composite material. The prepared nylon composite material has wide anti-microbial range, good sterilizing effect and excellent degrading performance, can meet the industrial requirements and further has a relatively good application prospect.

Description

Technical field [0001] The invention relates to the field of novel composite materials, in particular to an easily degradable antibacterial nylon composite material and a preparation method thereof. Background technique [0002] Polyamide is commonly known as nylon (Nylon), and its English name is Polyamide (PA). It is a general term for thermoplastic resins containing repeating amide groups—[NHCO]—on the main chain of the molecule. Including aliphatic PA, aliphatic-aromatic PA and aromatic PA. Among them, aliphatic PA has many varieties, large output and wide application, and its naming is determined by the specific carbon number of the synthetic monomer. The main varieties of nylon are nylon 6 and nylon 66, occupying an absolute dominant position, followed by nylon 11, nylon 12, nylon 610, nylon 612, and nylon 1010, nylon 46, nylon 7, nylon 9, nylon 13, new There are nylon 6I, nylon 9T and special nylon MXD6 (barrier resin), etc. There are many modified nylon varieties, such...
