Environment-friendly polyurethane antibiosis adhesive and preparation method thereof

Abstract

The invention discloses an environment-friendly polyurethane antibiosis adhesive and a preparation method thereof. The environment-friendly polyurethane antibiosis adhesive is prepared from the following raw materials in parts by weight: 10-30 parts of hexamethylene diisocyanate, 0.5-5 parts of antibacterial zeolite, 0.5-5 parts of tetrahydrofuran-ethylene oxide copolymerization glycol, 5-15 parts of dibutyl phthalate, 0.10-0.20 part of dibutyltin dilaurate, 0.2-2.0 parts of polyoxyethylene polyoxy propyl alcohol amidogen ether, 0.10-0.20 part of p-methyl benzol sulfonyl isocyanate, 0.10-0.20 part of gamma-glycidyl 3-(trimethoxysilyl)propyl ether and 0.10-0.30 part of triethylene glycol bis-[3-(3-tertiary butyl-4-hydroxy-5-methylphenyl) propionate]. According to the environment-friendly polyurethane antibiosis adhesive, the antibacterial property of the polyurethane adhesive is effectively improved, the application field of the polyurethane adhesive is widened, and the polyurethane antibiosis adhesive performs an active promotion function for the industrial production of the high-performance polyurethane adhesive and the wide application of the high-performance polyurethane adhesive in national industries.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to an adhesive, in particular to an environment-friendly polyurethane antibacterial adhesive and a preparation method thereof. Background technique [0002] The active functional groups contained in polyurethane adhesives can react with active functional groups such as hydroxyl groups in the substrate to form stable chemical bonds, so they show excellent adhesion and have been widely used in various fields of national industry. Become a key member of the adhesive family. [0003] However, polyurethane adhesives are restricted by their own molecular structure. When they are used in a humid environment and for a long time, they often cause the growth of bacteria, molds and other fungi, which seriously affects the actual efficacy and service life of the adhesive, and eventually leads to stickiness. The occurrence of delamination of the knot carrier. Therefore, the development of an envi...

Problems solved by technology

[0004] Antibacterial zeolite containing heavy metal ions such as silver ions, zinc ions, and copper ions is an environmentally friendly and economical high-efficiency antibacterial material. It has the advantages of simple preparation process, wide source of raw materials, obvious antibacterial effect, non-toxic and environmentally friendly, and has been widely used. In the fields of plastics and fiber products, it has effectively improved the service life and antibacterial properties of plastics and other products. However, the application of antibacterial zeolites containing heavy metal ions in reactive adhesives such as polyurethane adhesives has rarely been reported.
