Problems solved by technology

[0010] Common non-woven fabrics and various thermoplastic resin films appear wrinkled appearance, curling inside the film, insufficient glue fastness, and the phenomenon of glue opening still plagues the industry, resulting in a large number of defective rates
However, by increasing the amount of glue or changing the type of glue, as a laminated product commonly used in disposable products, it has brought great pressure on the cost, and at the same time greatly reduced the functional retention of the film, such as moisture permeability, etc.
Textile fiber products and thermoplastic resin films, such as polyurethane films, polyether ester films, etc., are prone to curling in the film after lamination, and the hand feels hard, resulting in the same cutting in the later stage and a decrease in comfort, which increases the cost of lamination. and process stability, especially the tension control accuracy has brought huge pressure, hindering the development of the market
This kind of phenomenon occurs seriously when thermoplastic resin film is laminated with other materials by pressure-sensitive adhesive, which puts forward strict requirements on the type of pressure-sensitive adhesive, increases technical difficulty, and limits the application of thermoplastic resin film

Embodiment 1

[0059] After 12μm polyurethane thermoplastic resin film and 190g / m2 gram weight polyester polyester four-sided stretch knitted fabric are laminated with reactive hot melt polyurethane glue, the glue weight is 6g / m2 and the production line speed is 30m / min, the laminated product is subjected to thermal post-treatment (hot pressing roll method) on-line at a temperature of 100°C, a pressure of 1.0 MPa, and cooling and winding. Then the glue is matured. The surface is smooth, the fabric is not curled toward the film surface, the softness ISO 17235-2002 test result is 3.4, the peel force GB8808-1988 test result is 6.0N / 15cm, and the softness test result of the laminated product without online thermal post-treatment It is 2.9, the peel force GB8808-1988 test result average is 4.5N / 15cm, and the appearance is curled.

Embodiment 2

[0061] The 5μm polyetherester thermoplastic resin film and 40g / m2 polyolefin PP non-woven fabric are sprayed and bonded with SIS type hot melt adhesive. The glue weight is 0.8g / m2 and the production line speed is 100m / min. The product undergoes online thermal post-treatment (hot press roll method), temperature 100 ℃, 1.0 MPa pressure, cooling and winding. The obtained surface is smooth, the non-woven fabric is not curled to the film surface, the softness ISO 17235-2002 test result is 6.2, the peel force JIS L1096 test result is 1.2N / 15cm, and the softness test of the laminated product without online thermal post-treatment The result is 5.0, and the average value of the peel force GB8808-1988 test result is 0.9N / 15cm.

Embodiment 3

[0063] The film surface of the laminated product prepared in Example 2 is sprayed and bonded with a 20g / m2 polyolefin PP non-woven fabric using SIS type hot melt adhesive. The glue weight is 1g / m2 and the production line speed is 100m. / min, the laminated product is subjected to online thermal post-treatment (hot pressing roll method) at a temperature of 100°C, a pressure of 1.0 MPa, and cooling and winding. The surface is smooth, the non-woven fabric is not curled toward the film surface, and there is no glue opening. The softness ISO 17235-2002 test result is 5.2, the peel force GB8808-1988 test result is 0.8N / 15cm, and the sticker without online thermal post-treatment The softness test result of the combined product is 4.8, and the average value of the peel force GB8808-1988 test result is 0.6N / 15cm.

Abstract

The invention relates to a thermoplastic resin film laminate prepared by a hot-pressing method. The laminate comprises at least one thermoplastic resin film layer with thickness of 1-250 mum, at least one thermoplastic resin product layer, and an adhesive layer between the thermoplastic resin film layer and the thermoplastic resin product layer and formed by glue. The thermoplastic resin product layer is a thermoplastic resin film or a thermoplastic resin fiber product, which can be textile fiber and / or non-woven. In the laminate provided by the invention, the fiber product has gram weight of 1-250g / m<2>; and the adhesive layer has gram weight of 0.1g / m<2>. The laminate provided by the invention has excellent air permeability, moisture permeability, smooth and wrinkle-free appearance and soft handle.

Description

Technical field [0001] The present invention relates to a thermoplastic resin film laminate and a preparation method thereof; more specifically, the present invention relates to a laminate composed of a thermoplastic resin film, a thermoplastic resin product and an adhesive, and a method for laminating the same. Background technique [0002] Laminated products of thermoplastic resin film and thermoplastic resin products are often faced with such phenomena as appearance wrinkles, curling in the film, hard hand feeling, insufficient glue fastness, and open glue, which have brought huge pressure on technology, market, and cost. Because the elasticity of thermoplastic resin film and fiber products are inconsistent, such as elastic film and inelastic fiber products, rigid film and elastic fiber products, ultra-thin film and ultra-thin fiber products, film and ultra-thin fiber products, elastic film and inelastic film Various differences have caused the above phenomenon, and various be...
