preparation example Construction

[0027] In some embodiments, the above-mentioned multifunctional protective fabric is prepared by the following steps

[0028] A: Process the above-mentioned thermoplastic polyurethane elastomer through casting, calendering or blow molding process to obtain a thermoplastic polyurethane elastomer film with a thickness of 0.005-0.2mm;

[0029] B: Apply the above-mentioned one-component polyurethane adhesive b evenly to the surface of the film in A by spraying or roller coating, and the sizing amount is 2-20g / m 2 , preferably 3-10g / m 2 ;

[0030] C: pressurize and compound the surface-coated film obtained in B with the protective fabric to obtain a multifunctional protective fabric.

[0031] or

[0032] D: Treat the fabric of the protective layer by spraying or in a high-humidity environment, so that the fabric absorbs an appropriate amount of water. The water content of the fabric is 0.5-5%, preferably 1-3%;

[0033] E: Apply the one-component polyurethane adhesive b to the s...

Embodiment 1

[0048] The thermoplastic polyurethane elastomer is M180 commercially available from Meirui (the mass ratio of polyethylene glycol ether is 55%, and 0.6% silver ion antibacterial agent GDJKP-02 is added)

[0049] The one-component polyurethane adhesive b is H680 commercially available from Meirui, a thermoplastic polyurethane elastomer adhesive with a melting point of 120°C and a viscosity of 10000cps (200°C)

[0050] The preparation process of the specific multifunctional fabric is as follows:

[0051] A: After the thermoplastic polyurethane elastomer M180 is processed by a casting process, a thermoplastic polyurethane elastomer film with a thickness of 0.05mm is obtained;

[0052] B: Apply the thermoplastic polyurethane elastomer adhesive H680 evenly to the surface of the film in A by roller coating, and the sizing amount is 5g / m 2 ;

[0053] C: Pressing and compounding the adhesive-coated film obtained in B and the protective fabric (polyester) to obtain a multifunctional ...

Embodiment 2

[0055] The thermoplastic polyurethane elastomer is M180 commercially available from Meirui (the mass ratio of polyethylene glycol ether is 55%, and 0.6% organic antimicrobial agent 5DIDP is added)

[0056] The one-component polyurethane adhesive b is a reactive polyurethane adhesive, and its preparation method is as follows: 80 parts of polyol (polyethylene glycol ether, molecular weight 2000), 30 ppm of phosphoric acid, and 0.1 part of antioxidant 1010 are added to the reaction kettle. Melting, mixing and stirring at 130°C, vacuuming and dehydration, the vacuum degree is -0.09MPa, and the vacuuming time is 2h;

[0057] Cool the material to 80°C, then add 20 parts of diphenylmethane 4,4 diisocyanate MDI, stir evenly, vacuumize and react under negative pressure, the vacuum degree is -0.09MPa, the reaction time is 1h, and the material is discharged to obtain the reactivity Polyurethane adhesive.

[0058] The preparation process of the specific multifunctional fabric is as follo...

Abstract

The invention belongs to the field of medical protectionfabrics, and relates to a multifunctional protectionfabric as well as a preparation method and application thereof. The fabric adopts the functional layer with a non-porous structure, and has the characteristics of water resistance, high moisture permeability, high water pressure resistance, static electricity resistance, no penetration of bacteria, viruses and body fluid and the like. Meanwhile, by introducing an antibacterial additive into the functional layer, the active disinfection function can be achieved, high-grade protection is provided in the field of medical protection, and meanwhile excellent wearing comfort and biochemical safety are achieved.

Description

technical field [0001] The invention relates to the field of medical protective fabrics, in particular to a multifunctional protective fabric. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Nowadays, medical protective fabrics are widely used, and high-quality medical protective materials can greatly improve the protective safety performance of medical staff, especially for some highly infectious bacteria and viruses, which can effectively protect and minimize the harm. GB19082-2009 "Technical Requirements for Medical Disposable Protective Clothing" requires that medical protective fabrics for clinical use must have the functions of blocking microorganisms, blocking body...
