preparation example Construction

[0026] On the other hand, the present embodiment provides a method for preparing a moisture-permeable film composite material, comprising: bonding a moisture-permeable layer on a non-woven fabric layer to prepare a moisture-permeable film composite material, and the formed material produces a waterproof and moisture-permeable film. The film composite material combines the characteristics of paper, film, cloth, etc., and has the advantages of wear resistance, aging resistance, high strength, light weight, smoothness, not easy to fluff, liquid penetration resistance, heat preservation and moisture permeability, etc. The bonding method can be Thermal bonding can also be used to bond the moisture permeable layer and the non-woven fabric together by means of an external adhesive.

[0027] In an embodiment, the specific steps of bonding the moisture-permeable layer on the non-woven fabric layer to prepare the moisture-permeable film composite material include:

[0028] S1, prepare t...

Embodiment 1

[0038] The non-woven layer is provided with two layers, which are arranged oppositely. The moisture-permeable layer is bonded in the middle of the two non-woven layers. The specific formula of the moisture-permeable layer includes 95wt% TPEE, 4wt% binder and 1wt% cooling masterbatch.

Embodiment 2

[0040] The non-woven layer is provided with two layers, which are arranged oppositely. The moisture-permeable layer is bonded in the middle of the two non-woven layers. The specific formula of the moisture-permeable layer includes 88wt% TPEE, 4wt% adhesive, 1wt% cooling masterbatch and 7wt% elastomeric material.

Abstract

The invention relates to a moisture-permeable film composite material and a preparation method thereof. The moisture-permeable film composite material comprises at least one non-woven fabric layer and a moisture-permeable layer, wherein the moisture-permeable layer and the non-woven fabric layer are bonded with each other; the moisture-permeable layer is prepared from TPEE, an adhesive and other auxiliaries, the content of the TPEE is 88 to 95 percent by weight, the content of the adhesive is 2 to 4 percent by weight, and the content of the other auxiliaries is 0 to 10 percent by weight. The moisture-permeable film composite material has a multi-layer structure and is composed of the non-woven fabric layer and the moisture-permeable layer, the non-woven fabric layer and the moisture-permeable layer form the laminated film composite material, and the moisture-permeable layer forms a layer of film on the surface of the non-woven fabric. Furthermore, the moisture-permeable layer mainly comprises a TPEE material, the TPEE material has non-porous hydrophilic functional groups and can take away sweat gas of a human body and block liquid, and the non-woven fabric has good liquid resistance and surface strength, so that the moisture-permeable film composite material has good moisture permeability while having certain surface strength.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a moisture-permeable film composite material and a preparation method. Background technique [0002] In recent years, with the development of industrial technology and the improvement of people's living standards, the market's demand for moisture-permeable and waterproof materials (clothing, shoes, hats and outdoor products) for protection has increased day by day. Materials with hygroscopicity, breathability, touch and other characteristics are widely favored. [0003] Waterproof & Moisture Permeable Fabric (Waterproof & Moisture Permeable Fabric), the so-called waterproof and moisture permeable performance of the fabric, means that the fabric is not penetrated by water under the action of a certain pressure of water, but the sweat vapor emitted by the human body can diffuse or be transmitted to the outside world through the fabric. 1mL of human sweat is about 23 million water...
