Embodiment 1

[0029] 10g of ethylene-vinyl acetate copolymer (Dow Pont, 40L-03) and 2.6mg of benzalkonium chloride (Zaozhuang Kairui Chemical Co., Ltd.) were added to 90g of 70% cyclohexane by mass at 25°C at room temperature. and 30% by mass of isopropanol in a mixed solvent, and stirred for 24 hours until completely dissolved. Filter through 800 mesh filter screens, obtain coating solution, with anilox roller, 10 μm thick coating solution is coated on polyethylene microporous membrane (U.S. Dow DuPont, Tyvek 1056, porosity 80%), and dried at 50°C to obtain a water molecule permeable membrane.

Embodiment 2

[0031] 10g polyurethane emulsion (Wanhua Chemical Group, 1651), 2g water-based curing agent 161 and 40 mg of nano-silver antibacterial agent (Jinda Nano Technology (Xiamen) Co., Ltd., JDTKS-001) were added to 28 g of deionized water, and stirred until uniformly dispersed. Filter through a 200-mesh filter screen to obtain the coating solution, and apply the 10 μm thick coating solution to the polypropylene microporous membrane (Wuhu Huamei Microporous Membrane Factory, porosity 85%) with an anilox roller, and Dry at 80°C to obtain a water molecule permeable membrane.

Embodiment 3

[0033] Add 10 g of sulfonated polyethersulfone (Changzhou Kete Chemical Co., Ltd.) and 0.85 mg of benzalkonium chloride (Zaozhuang Kairui Chemical Co., Ltd., JDTKS-001) to 90 g of N,N-dimethyl In base formamide, stir for 24h until fully dissolved. Filter through an 800-mesh filter screen to obtain the coating solution, and apply the 10 μm thick coating solution to the polyvinylidene fluoride microporous membrane (Jiangsu Lantianpeier Membrane Industry Co., Ltd., porosity 90%) with an anilox roller , and dried at 180°C to obtain a water molecule permeable membrane.

Abstract

A water molecule permeable membrane and a preparing method and application thereof are disclosed. The method includes adding a film forming substance of a polymer film and an antibacterial material into a solvent, fully mixing the mixture, filtering the mixture with a filter screen to obtain a coating solution, coating a hydrophobic porous base membrane with the coating solution through an aniloxroll, and drying the product to form a hydrophilic polymer film on the hydrophobic porous base membrane to obtain the water molecule permeable membrane. The water molecule permeable membrane includesthe hydrophobic porous base membrane and the hydrophilic polymer film covering the base membrane. The water molecule permeable membrane has a high water molecule penetration rate, can be used for water-mist-free sterile water molecule humidifiers, and allows tap water to rapidly pass through the permeable membrane in a form of water molecules and diffuse to the environment by applying a fan. The water molecule permeable membrane is healthy and energy-saving.

Description

technical field [0001] The invention relates to the technical field of water molecule permeable membranes, in particular to a water molecule permeable membrane, a preparation method thereof and an application in a water molecule humidifier. Background technique [0002] Air humidity has an important influence on the comfort of the human body. Existing studies have shown that people are prone to symptoms such as thirst and dry cough when the relative humidity is lower than 30%, and it is very easy to induce diseases such as pharyngitis. Therefore, proper humidification of the environment in dry areas and dry seasons such as autumn and winter is beneficial to good health. [0003] The existing humidifiers on the market include ultrasonic humidification, spray humidification, wet film humidification, steam humidification and other forms. The Chinese invention patent application with the application number 201710966759.9 (the application publication number is CN107575980A) dis...
