Embodiment 1

[0024] The sponge with a porous three-dimensional structure is used as the matrix. The size of the sponge is 20 cm (length) * 20 cm (width) * 20 cm (height). The central part of the sponge is relatively large, and the external void is relatively small. Immerse the sponge as a whole in the polyurethane hydrophilic finishing agent for 1 minute, take it out, pad and dry it, and the sponge will have a hydrophilic function.

[0025] Then immerse the five sides of the sponge body in a 5 cm deep silicone water-repellent finishing solution for 1 minute, take it out and put it in an oven at 130°C for 3 minutes, and keep the water-repellent finishing sponge during the drying process The droplet contact angle on the body surface is greater than 110 degrees.

[0026] Then immerse the five surfaces after water-repellent finishing in the silicone water-repellent finishing solution 3 cm deep for 1 minute, take it out, and put it in an oven at 140°C for 3 minutes to dry. The droplet contact ...

Embodiment 2

[0030] The multi-space knitted spacer fabric is used as the base, and the size of the multi-space knitted spacer fabric is 20 cm (length) * 10 cm (width) * 0.2 cm (height). The gap of the spacer fabric is relatively large, and the external space is relatively small. The spacer fabric is immersed in the polyurethane hydrophilic finishing agent for 1 minute, and after being taken out, padded and dried, the spacer fabric has a hydrophilic function.

[0031] Then immerse the upper surface of the spacer fabric in a 0.02 cm deep water-repellent finishing agent solution containing paraffin wax for 1 minute, take it out and put it in an oven at 130°C for 3 minutes to dry, and keep the liquid droplets on the upper surface during the drying process The contact angle is greater than 110 degrees; then immerse the lower surface of the spacer fabric in a 0.02 cm deep water-repellent finishing agent solution containing paraffin wax for 1 minute, take it out and put it in an oven at 130°C for ...

Abstract

The invention provides a liquid storage core and a preparation method thereof. The liquid storage core comprises a primary water repellent layer, secondary water repellent layers and a substrate madeof a flexible three-dimensional material, the surface of the substrate is wrapped with the primary water repellent layer and at least a notch is left in the primary water repellent layer to form an inlet for external liquid to enter the substrate, the secondary water repellent layers are located between the primary water repellent layer and the substrate, the water repellent capacity of the primary water repellent layer is higher than that of the secondary water repellent layers, and the core is prepared through multiple times of water repellent finish. The liquid storage core is simple in preparation method and low in cost, and industrial production is easy. The prepared liquid storage core has better liquid permeability and gas permeability than a conventional liquid storage device, theinterior stored with the liquid has certain compression resistance and deformation resistance, and the liquid storage core can be embedded in other products, can more conveniently collect multiple tissue fluid in the case of small and uncertain flow, and has a wide range of application.

Description

technical field [0001] The invention relates to a liquid storage core body and a preparation method thereof, which are mainly used in the field of liquid collection and storage. Background technique [0002] The collection, storage and analysis of liquid is an important requirement in the field of liquid transmission and control such as medical health, liquid pollutant monitoring, and horticultural management. Traditional liquid storage tools such as liquid storage bladders and liquid storage bags have poor air permeability, compression resistance and deformation resistance, and cannot be used in small and uncertain flow conditions, and their application fields are relatively limited. Therefore, it is of great significance to propose a liquid storage core with good air permeability, good compression and deformation resistance, wider application range and lower cost. Contents of the invention [0003] The invention provides a liquid storage core and a preparation method th...
