Problems solved by technology

Antibacterial finishing agents include organic antibacterial agents and inorganic antibacterial agents. For example, commonly used nano-scale antibacterial fabrics have been widely used in recent years. Agglomeration will occur, resulting in mutual coverage and uneven distribution of nanomaterials, which will greatly reduce the antibacterial effect
For this reason, in the prior art, the use of carriers to load nanomaterials has appeared, but there are also the characteristics of low surface loading rate and poor adhesion between carriers and antibacterial nanomaterials.

Embodiment 1

[0016] The preparation of embodiment 1 modifying agent

[0017] Modifier used in the present invention is the compound with following general structure:

[0018]

[0019] In the above general structure, A is the residue after the reaction of 4-hydroxyethylimidazole and isocyanate group; R is the part of diphenylmethane-4,4,-diisocyanate except the isocyanate group. Wherein, m and n are integers, and 5≤m≤10, 3≤n≤5. The modifier consists of diphenylmethane-4,4,-diisocyanate and polyether polyols with different degrees of polymerization in toluene, acetone and other organic solvents in a certain proportion to form polyurethane with isocyanate groups at both ends of the molecular chain. Then add 4-hydroxyethylimidazole to block it and prepare it. During the reaction, in order to increase the reaction speed, the catalyst dibutyltin dilaurate can be used to control the degree of polymerization of the polyether polyol used to control the general formula The m value in the struct...

Embodiment 2

[0020] Embodiment 2 antibacterial additive A

[0021] The antibacterial additive described in the present embodiment is prepared by the following method:

[0022] (1) adding calcium carbonate particles with an average particle diameter of 10 μm into water to form a suspension with a concentration of 10wt%, then adding nanometer titanium dioxide particles and 1-vinylimidazole, controlling the temperature of the system to be 20 to 30°C, and Stirring and reacting for 30 minutes at a stirring speed of 2000rpm; wherein the average particle diameter of the nano-titanium dioxide is 20nm, the quality of the nano-titanium dioxide is 10wt% of the calcium carbonate quality, and the quality of 1-vinylimidazole is 3.0wt% of the calcium carbonate quality;

[0023] (2) Add silver nitrate, citric acid, glucose and N-vinylcaprolactam, and react at a stirring speed of 2000rpm for 20 minutes; then age for 12 hours, filter, dry and disperse to obtain nano-coated calcium carbonate particles Where...

Embodiment 3

[0035] The preparation of embodiment 3 polyurethane functional coating agent A

[0036] Under the protection of dry nitrogen, polyoxypropylene diamine D-2000 after vacuum dehydration, bisphenol A polyoxyethylene ether BPE-06, carbodiimide modified 4,4,-MDI, N-methyl di Ethanolamine, 1,4-butanediol, antibacterial additive A, diethylaminoethyl methacrylate, tetraisobutyl titanate, ultraviolet absorber, antioxidant, 8-hydroxyquinolinone and an appropriate amount of solvent ( Add raw materials such as toluene and ethyl acetate) into the reactor at one time, react at 75-80°C for 2.0 hours, lower the system temperature to 20-30°C, and then add deionized water, sodium carboxymethylcellulose, polyethylene Pyrrolidone and fatty alcohol polyoxyethylene ether are dispersed for 15 to 20 minutes under the stirring condition of 3000 rpm, and then the solvent and low boilers are removed under reduced pressure to obtain the polyurethane functional coating agent. In this example, carbodiimide...

Abstract

The invention relates to an antimicrobial fabric for a medical partition curtain, belonging to the technical field of medical fabrics. The antimicrobial fabric comprises a piece of fabric base cloth and a polyurethane functional layer, wherein a polyurethane functional coating agent is applied to the fabric base cloth and then is cured to form the polyurethane functional layer. The polyurethane functional layer of the antimicrobial fabric has a stable and lasting antimicrobial function, and is capable of killing bacteria and inhibiting bacterial reproduction in a contact manner so as to further achieve the aim and effect of resisting bacteria in a long time; in addition, the antimicrobial fabric can be endowed with excellent waterproofness and moisture penetrability by virtue of the polyurethane functional layer.

Description

technical field [0001] The invention relates to the technical field of medical fabrics, more specifically, the invention relates to an antibacterial fabric used for medical curtains. Background technique [0002] Antimicrobial Fabric (AntimicrobialFabric), used to resist the regeneration and reproduction of Staphylococcus aureus and Escherichia coli. Antibacterial fabrics are mainly divided into the following two categories according to the preparation process: the first is the built-in silver ion antibacterial fabric, which uses spinning-grade antibacterial technology to directly put the antibacterial agent into the chemical fiber; the second is the antibacterial finishing technology through The subsequent shaping process of the fabric is added. The finishing process is relatively simple and the cost is low, and it is also the most widely used one in the market. Antibacterial finishing is to make the fabric have antibacterial and bactericidal functions through the treatme...
