Abstract

The invention discloses a graphene-containing polyurethane antimicrobial adhesive and a preparation method thereof. The graphene-containing polyurethane antimicrobial adhesive is prepared from the following raw materials in parts by weight: 5-20 parts of polyisocyanate, 0.2-2 parts of functionalized graphene, 40-60 parts of polylol, 10-20 parts of plasticizer, 0.05-0.15 part of catalyst, 0.1-1.5 parts of defoaming agent, 0.05-0.10 part of dehydrator, 0.05-0.20 part of coupling agent and 0.05-0.20 part of antioxidant. The method effectively improves the antibacterial property of the polyurethane adhesive and widens the application range of the polyurethane adhesive, thereby performing an active promoting function on industrial production of the high-performance polyurethane adhesive and wide application of the polyurethane adhesive in national industry.

Description

technical field [0001] The invention relates to a polyurethane antibacterial adhesive with graphene and a preparation method thereof, belonging to the technical field of adhesive production. Background technique [0002] Polyurethane adhesives are able to form a good chemical bond with the substrate and therefore exhibit excellent bonding. After decades of rapid development, polyurethane series adhesives have been widely used in various fields of national industry. [0003] However, in the actual application of polyurethane adhesives, when the temperature and humidity conditions are suitable, bacteria, molds and other fungi will often grow, which will seriously affect the aesthetics, service life and actual functions of the application carrier. Therefore, the development of polyurethane adhesives with excellent antibacterial properties has important social significance, and can also bring huge market returns. [0004] Graphene is called "the material of the 21st century". ...
