Elastic composite material with massaging and breathing effect

Abstract

The present invention relates to one stretched complex material which has massage and air permeability, it includes one elastic base-layer which is foaming rubber and has a break extensibility of 50-500% and a strength of extension more than 4Kg / cm2, the other is bonding on outer layer. These elastic base-layers are both have an intrinsic surface and an exterior one, both have some air vents which prong those exterior layers, and many protrusion of surface from the intrinsic surface. Every air vent has an intrinsic hatch and an exterior one, the ratio of the area of the intrinsic hatch and the exterior one is between 1.2 and 5.0, and the area of all the intrinsic hatches is less than 30 percent of all the area of the intrinsic surface of the elastic base-layers, at the same time, the height of these heaves is between 0.5 centimeters and 6 centimeters and the area of the cross section is less than 25 square centimeters.

Description

technical field [0001] The invention relates to an elastic composite material, in particular to an elastic composite material suitable for use on various protective gear and shoes in contact with the human body and animals, and capable of massage and breathability under the premise of being soft, elastic and warm. Elastic composite. Background technique [0002] In the past technology, in order to make the rubber have good elasticity, foaming substances and various additives are usually added to the process to form closed air cells when the rubber is formed. Laminating products such as cloth can be used on items such as shoes, elastic clothing, elastic pads, etc., but because the closed air cells cannot produce a breathable effect, this type of elastic composite material will be subject to some restrictions in application.

Problems solved by technology

[0002] In the past technology, in order to make the rubber have good elasticity, foaming substances and various additives are usually added to the process to form closed air cells when the rubber is formed. : Laminated products such as cloth can be used on items such as shoes, elastic clothing, elastic pads, etc., but because the closed air bubbles cannot produce a breathable effect, the application of this type of elastic composite material will be subject to some restrictions

[0003] In order to make some protective gear used in sports or medical treatment have better air permeability, some elastic composite materials will set through holes on the rubber elastic body, and attach a breathable product on the surface of the rubber elastic body , although this kind of elastic composite material in the past can improve air permeability, it often cannot take into account both air permeability and thermal insulation in the design of the through holes. The pore size is too small to provide good air permeability

In addition, in the past, elastic composite materials with breathable effects did not have the effect of massaging, and in the combination of laminated products, it was also prone to defects such as delamination or material stiffness, which affected the comfort of use
