Problems solved by technology

Due to the incompatibility of the two systems, antibacterial agents and antistatic agents will migrate over time, which not only reduces the antibacterial and antistatic functions of the material, but also precipitates heavy metals and low-molecular organic substances to further aggravate environmental pollution.

Embodiment 1

[0043] 1. The antibacterial emulsion is prepared from the raw materials in the following weight ratio according to the following steps:

[0044]

[0045] The preparation of antibacterial and antistatic emulsion includes two parts: the synthesis of acryloyloxyethyl dimethyl ethyl ammonium bromide and the synthesis of antibacterial and antistatic emulsion

[0046] (1) Synthesis of functional monomer acryloyloxyethyl dimethyl ethyl ammonium bromide

[0047] ① Preparation of Acryloyl Chloride

[0048] In a three-neck flask equipped with a condenser, a thermometer and a dropping funnel, add thionyl chloride and a small amount of polymerization inhibitor. At room temperature, add 0.2 parts of refined acrylic acid monomer dropwise under magnetic stirring at 300 rpm. Raise the temperature to 35°C, react for 3 hours, cool to room temperature, and distill under reduced pressure to prepare acryloyl chloride.

[0049] ② Preparation of dimethylaminoethyl acrylate

[0050] Add dimethy...

Embodiment 3

[0081]

[0082]

[0083] ① Preparation of Acryloyl Chloride

[0084] In a three-necked flask equipped with a condenser, a thermometer and a dropping funnel, add thionyl chloride and a small amount of polymerization inhibitor. At room temperature, add 1.2 parts of refined acrylic acid monomer dropwise under magnetic stirring at 500 rpm. Raise the temperature to 45°C, react for 5 hours, cool to room temperature, and distill under reduced pressure to prepare acryloyl chloride.

[0085] ② Preparation of dimethylaminoethyl acrylate

[0086] Add dimethylethanolamine, 10 parts of solvent and a small amount of polymerization inhibitor sequentially into the three-necked flask, slowly add acryloyl chloride dropwise under ice-water bath at 500 rpm under magnetic stirring, and keep reacting under ice-water bath for 4 hours after the dropwise addition. After the reaction is completed, filter the mixed solution in the bottle, and distill the obtained filtrate under reduced pressure t...

Abstract

The present invention discloses antibacterial antistatic emulsion and coating and their preparation method; the antibacterial antistatic emulsion is mainly prepared from the following components according to parts by weight: 2.79-4.78 parts of acrylic acid; 0.4-2 parts of thionyl chloride; 0.01-0.03 part of a polymerization inhibitor; 0.3-1.6 parts of dimethylethanolamine; 0.39-1.9 parts of bromoethane; 10-20 parts of a solvent; 11.27-14.32 parts of methyl methacrylate; 12.36-16.7 parts of isobutyl methacrylate; 9.54-13.52 parts of butyl acrylate; 50-55 parts of deionized water; 0.11-0.21 part of an initiator; 0.16-0.21 part of KH550; and 0.88-1.52 parts of glycidyl methacrylate. The antibacterial antistatic emulsion and coating have good antibacterial and antistatic functions and have good low-temperature stability.

Description

technical field [0001] The invention relates to an antibacterial and antistatic preparation method, which can be used in fields requiring antibacterial and antistatic. Background technique [0002] In daily life, people stay indoors most of the time, so the quality of indoor air has attracted more and more attention. Microorganisms are widely distributed in the environment, and the microorganisms in the indoor air are sampled. In rural areas, the total number of bacteria is 138.94cfu / cm2, and in urban areas, the total number of bacteria is 72.10cfu / cm2. Therefore, in interior decoration, antibacterial materials, such as antibacterial doors and windows, antibacterial coatings, antibacterial Plastics and antibacterial mulches are playing an increasingly important role. Among them, antibacterial coatings can be directly coated on the surface of objects, and are therefore more popular because of their ease of use. [0003] Conventional antibacterial coatings are to add various...
