Problems solved by technology

Inorganic antibacterial agents mainly disperse silver, copper, zinc and other metals or metal ions in materials to prepare antibacterial materials, but long time will cause antibacterial agents to migrate, resulting in unsustainable antibacterial effect
Organic antibacterial agents include small molecules such as acids, esters, alcohols, phenols, and quaternary ammonium salts. These small molecules also migrate in materials and are highly toxic, which largely limits their use.
Natural antibacterial materials mainly include chitosan extracted from shrimp and crab shells, which is difficult to extract and has poor heat resistance
Therefore, in terms of practical application, the above materials alone cannot perfectly meet the market demand, and the research on long-acting composite antibacterial materials is a current hot issue

preparation example Construction

[0060] In step 1, the preparation method of zinc tetranitrophthalocyanine solid powder comprises the following steps:

[0061] Step 1.1, respectively add 20-25% of 4-nitrophthalonitrile, 5-10% of zinc acetate dihydrate, and 65-75% of ethylene glycol into a three-necked flask equipped with a stirrer;

[0062] Step 1.2. Fill the three-necked flask with nitrogen and then seal the reaction under the heating condition of 140-160°C for 22-26 hours. After the system is cooled, take it out into the methanol solution;

[0063] Step 1.3: perform suction filtration and washing in sequence until the filtrate is colorless, and vacuum-dry at 45-55° C. to obtain the zinc tetranitrophthalocyanine solid powder.

[0064] In step 2, the preparation method of tetraaminophthalocyanine zinc solid powder comprises the following steps:

[0065] Step 2.1, respectively adding 10-15% of the zinc tetranitrophthalocyanine solid powder obtained in step 1.3, 45-55% of sodium sulfide nonahydrate, and 35-40%...

Embodiment 1

[0103] Add 33.12g of 4-nitrophthalonitrile, 10.5g of zinc acetate dihydrate, and 95.64g of ethylene glycol into a three-necked flask equipped with a stirrer, fill it with nitrogen, and conduct a sealed reaction under heating at 150°C for 24 hours. After the system was cooled, it was added to methanol solution, then suction filtered, washed until the filtrate was colorless, and finally dried in vacuum at 50°C to obtain a dark green powder, which was zinc tetranitrophthalocyanine solid.

Abstract

The invention discloses a synthesis method and application of a UV-cured bactericidal anti-static resin material, and belongs to the technical field of photodynamic antibacterial agents, and the synthesis method comprises the following four steps: preparation of tetraamino zinc phthalocyanine, preparation of a photocuring adhesive, coating and photocuring. The tetranitrophthalocyanine zinc is synthesized by adopting an inert solvent method, the sodium sulfide nonahydrate is used for reducing zinc tetranitrophthalocyanine into zinc tetraaminophthalocyanine, unsaturated double bonds are graftedon zinc tetraaminophthalocyanine for UV photocuring, the prepared light-curing film has efficient sterilization performance, can reach the escherichia coli resistance rate of 95% or above after beingformed, and is permanent.

Description

technical field [0001] The invention relates to the technical field of photodynamically active photosensitive bactericidal resin and antistatic resin, in particular to a synthesis method and application of a UV cured bactericidal antistatic resin material. Background technique [0002] With the rapid popularization of smart devices, the frequency of use of electronic products with display screens is increasing year by year. In order to prevent the screen from being damaged due to scratches or bumps, a series of anti-scratch films came into being. However, studies in recent years have found that electronic products are prone to breed bacteria during use, which affects human health. In order to effectively prevent the spread and cross-infection of bacteria and improve people's health, it is of great significance to study a new type of antibacterial material and apply it to the surface of electronic products to inhibit the spread of bacteria. [0003] At present, the antibact...
