Embodiment 1

[0052] A composite polymer laminated fabric, comprising a fabric substrate layer, a 100 μm substrate melt adhesive layer, an adhesive layer and a 0.2mm composite polymer layer. The substrate melting layer is composed of part of the fabric structure of the fabric substrate and the adhesive intersecting, and the fabric structure in the fabric substrate layer is integrated with the fabric structure in the substrate melting layer; the adhesive layer and the substrate The glue-melt layer forms an integral body; the composite polymer layer is pasted on the fabric substrate layer through the adhesive layer.

[0053] In this embodiment, the fabric base material is made of polyester yarns through plain weaving process.

[0054] The composite polymer layer includes the following components in parts by mass:

[0055] EVA resin 25

[0056] PP20

[0057] PE-g-MAH 5

[0058] TPU 15

[0059] Superfine Calcium Carbonate 22

[0060] Release agent 1

[0061] Colorant 2.

[0062] In the ...

Embodiment 2

[0074]The laminated fabrics of this embodiment are substantially the same as those of the preferred embodiment, except that their fabric substrates are slightly different, their calendered layer formulations are slightly different, and their adhesive formulations are slightly different.

[0075] Specifically, the fabric substrate layer is a blended fabric of PET and nylon composite fibers, and the weave is a plain weave.

[0076] In this embodiment, the thickness of the part of the adhesive layer that is thermally pressed into the fabric tissue of the fabric substrate layer is 50 μm. In the pasting process, the pressure of the roller press is 0.5MPa, and the vehicle speed is 35m / min. The amount of glue applied to the adhesive is 100g / m 2 . The yarn denier of the fabric substrate is 600D.

[0077] The adhesive layer adopts a roller coating process, the viscosity of the adhesive is 5000cps, the glue coating temperature is room temperature, and the controlled glue amount is 10...

Abstract

The invention relates to a composite polymer laminated fabric. Including fabric base material layer, base material melt glue layer, adhesive layer and composite polymer calendering layer, base material melt glue layer is composed of fabric base material layer of partial thickness, adhesive agent layer and composite polymer calendering layer of partial thickness A common composition; part of the adhesive layer and a partial thickness of the composite macromolecular calendering layer are embedded in the fabric tissue voids of the fabric substrate, thereby forming the substrate melting layer; the composite macromolecule component is made of EVA It is an essential component, and other components are added. The present invention enables the present invention to produce a base material melting glue layer through the selection of the fabric base material, the selection of the adhesive, and the improvement of the process parameters, and based on the base material melting glue layer, the present invention is compared with the existing The technology has made significant progress, especially in terms of the bonding fastness of the PVB layer, the feel after buckling, and the recovery of wrinkles.

Description

technical field [0001] The invention relates to a laminated fabric, in particular to a composite polymer laminated fabric and its preparation method. Background technique [0002] Laminated fabrics, also known as bonded fabrics, laminated fabrics. It refers to the bonding of fabrics and other film materials to form a composite material with multiple functions, which is applied to raincoats, tents, etc. [0003] Lamination method is a forming process that combines multiple layers of the same or different materials into a whole by heating and pressure. It is often used in plastic processing and also in rubber processing. For thermoplastics in plastic processing, the calendered plastic sheets are often laminated into a whole board; on the calender, the newly formed plastic film and fabric can be laminated to form artificial leather products. For thermoset plastics, lamination is an important method of manufacturing reinforced plastics and articles. Laminate reinforced materi...
