High-toughness high-strength flexible memory composite material
Technical Field
The utility model relates to a technical field of medical bandage especially relates to a flexible memory combined material of high tenacity high strength.
Background
As is well known, textile materials are characterized by being light, thin, elastic or inelastic, soft, good in skin-friendly property, but not good in stiffness;
as the connecting piece of wearing use, generally adopt the plastic material, like PP, TPE etc.. The plastic part can be molded by injection, and is made of a harder material, so that the connecting piece can be ensured not to deform, but is airtight and has poor skin-friendly feeling;
in order to achieve better skin-friendly performance, a plurality of connecting pieces for respirators on the market can combine the two materials, namely cloth or composite cloth and a plastic part by adopting ultrasonic, gluing, secondary forming and other processes, and is characterized in that the skin-sticking surface is cloth, and the fixing surface is plastic or silica gel and other materials. In wearing equipment, particularly breathing machine connectors, plastic (silicone) parts are often used as the connection between the headgear and the mask. The plastic part has the characteristics of hardness, air impermeability and poor skin friendliness. In the prior art, the connecting piece is improved, such as the cloth is attached to plastic, rubber, silica gel and the like, so that the connecting piece has the strength of the plastic and is comfortable to wear. However, the fabric is not breathable, and is easy to cause allergy and rash after being worn for a long time, thereby bringing inconvenience and problems to the wearer.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a have good gas permeability, can reduce allergy or the phenomenon of erythra to have the high tenacity high strength's of good deflection, intensity and travelling comfort flexible memory combined material.
The utility model discloses a flexible memory combined material of high tenacity high strength, including top layer, lower top layer and intermediate layer, the intermediate layer is located the top layer and between the lower top layer to all be provided with the intermediate layer between top layer and lower top layer and the intermediate layer.
The utility model discloses a flexible memory combined material of high tenacity high strength, the upper epidermis is the cloth fabrics with lower top layer.
The utility model discloses a flexible memory combined material of high tenacity high strength, interbedded material is the heat setting cotton.
The utility model discloses a flexible memory combined material of high tenacity high strength, the material in intermediate level is compound bubble cotton or thick cloth.
The heat-set cotton has good characteristics:
1. heat setting property; the material is hardened and shaped after being heated, can be shaped into different curved surfaces, concave-convex shapes, textures, special shapes and the like according to design requirements, has good repeated shaping performance, and can be repeatedly shaped;
2. high strength and high toughness; the material has higher strength, the width of 10mm after heat setting and the thickness of 0.5mm, the tensile force of the material is more than or equal to 60N, and the tensile force of the material with the thickness of 1mm is more than or equal to 150N;
3. the washing resistance is realized; the material is not deformed when being washed by water and is not dissolved in water, and the material is not deformed when meeting water after being heat-set;
4. the memory is good; the sandwich material is not folded after being shaped, and can restore the original shape after being bent.
Compared with the prior art, the beneficial effects of the utility model are that: this material has the stiffness and the intensity of plastics to have the comfortable compliance of cloth, advantages such as the design/formability of the technology of moulding plastics in addition, and the used material of this combined material is the fabrics (there is the bubble cotton or does not have the bubble cotton), does not use plastic material (like PP, PE, PA, TPE etc.) or technology (like moulding plastics, blow molding, die-casting etc.), simultaneously the utility model discloses a combined material, its two sides and edge are the cloth, and soft skin, the travelling comfort is good to this material can be according to the demand of part, makes into whole inelasticity or local inelasticity.
