Abstract

The invention relates to a nano-silver antibacterial spray-molded protective film. The protective film is characterized by comprising the following components in parts by weight: 20-50 parts of a resin material, 10-20 parts of a nano-silver dispersing agent, 30-60 parts of a solvent, 0-3 parts of a coalescing agent and 0.5-2 parts of a hyperdispersant. The nano-antibacterial spraying agent can protect the surface of an object against scratching, skid and aging, can be easily peeled off, and is high in practicability and wide in application range.

Description

technical field [0001] The invention relates to an antibacterial protective film, in particular to a protective film formed by nano-silver antibacterial spraying and a preparation method thereof. Background technique [0002] Nano-silver is a simple silver particle with a particle size of nanometer level. It has been widely proved that this particle has a strong inhibitory and killing effect on several pathogenic microorganisms, and there are already coatings based on nano-silver antibacterial technology on the market. Spray, fabric and other products, widely used. However, the existing spraying materials based on nano-silver antibacterial technology generally have disadvantages such as poor durability, weak protection, and narrow application range, so further improvements are needed. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the above-mentioned prior art, and provide a protective film formed by nano-silver ...
