Antibacterial mildew-proof ultraviolet-resistant foamed material and preparation method thereof

Abstract

The invention discloses an antibacterial mildew-proof ultraviolet-resistant foamed material and a preparation method thereof. The antibacterial mildew-proof ultraviolet-resistant foamed material is prepared by subjecting, by weight, 15 to 25 Phr of an ethylene-vinyl acetate copolymer (EVA), 20 to 30 Phr of novel plastic particles, 20 to 30 Phr of regenerated polyethylene, 1 to 4 Phr of a foaming agent, 0.5 to 1 Phr of zinc oxide, 0.5 to 1.0 Phr of stearic acid, 0.1 to 0.5 Phr of an odorless cross-linking agent, 0.1 to 0.5 Phr of an ultraviolet light absorber, 0.1 to 0.5 Phr of antibacterial agent and 10 to 50 Phr of calcium carbonate to batching, open mixing, preparation of sheets, vulcanization and foaming, cooling and molding, and processing. The prepared foamed material has good softness, excellent hand feel, slip resistance, elasticity, compression performance, ultraviolet resistance and antibacterial and mildew-proof performance; a product prepared from the material has prolonged service life, long-lasting beautiful appearance and ultraviolet ray-absorbing and antibacterial functions; and the performance of the product and the performance of the foamed material do not affect each other.

Description

technical field [0001] The invention relates to the field of foaming materials, in particular to an antibacterial, anti-mildew and anti-ultraviolet foaming material and a preparation method thereof. Background technique [0002] Foaming material refers to the foaming material that gasifies and generates bubbles inside the material to make it a porous material. It has the advantages of light weight, high specific strength, excellent insulation performance, significant cushioning capacity and strong adsorption capacity, and has been widely used. In the automotive industry, construction industry, packaging industry, agriculture, water treatment and air filtration and other fields; such as the manufacture of foam plastics, foam rubber, foam resin, etc. [0003] When foaming materials are applied to yacht foot mats, floor mats, bathroom mats, etc., it is easy to breed bacteria in contact with the floor, which is more harmful to human health. In addition, in other application fiel...

AI Technical Summary

Problems solved by technology

[0003] When foaming materials are applied to yacht foot mats, floor mats, bathroom mats, etc., it is easy to breed bacteria in contact with the floor, which is more harmful to human health. In addition, in other application fields exposed to sunlight, due to sunlight The thread contains a large amount of ultraviolet light harmful to colored objects, and its wavelength is about 290-460 nanometers. These harmful ultraviolet light will decompose and fade the color molecules through chemical oxidation and reduction. If the foaming material does not have certain ultraviolet resistance , will also reduce the service life of its products and the durability of appearance aesthetics

[0004] At present, there is also a simple method of adding some anti-ultraviolet agents and antibacterial agents to the foaming material, but it is usually difficult to absorb the ultraviolet rays in sunlight and fluorescent light sources, inhibit the growth of bacteria, and prevent the growth of the foaming material. A win-win situation that does not affect its own performance
