Abstract

A manufacturing method for a foaming synthetic leather material comprises the following steps: firstly performing cross-linked foaming to form a substrate, slicing the substrate to form two blank plates which have a joint surface respectively, and fixing the joint surfaces of the blank plates on a fabric layer. Therefore, the leather material is fully reacted by cross-linked foaming, and has internal stomata with a high density and a low proportion, which allow the generation of physical properties such as good elasticity, attaching property, softness, and the like.

Description

The manufacture method of the synthetic cladding of foaming

Technical field

The present invention relates to the synthetic cladding of a kind of foaming, particularly relate to a kind of manufacture method of the synthetic cladding that foams.

Background technology

The synthetic cladding of foaming has been widely used in daily living article, such as suitcase, vamp, clothes, sofa, furniture, sphere ...

The synthetic cladding manufacture method of existing a kind of foaming, as shown in Figure 1, on a tissue layer 3, carry out gluing, drying glue operation in advance, then, utilize an extrusion equipment 6 with fusion and contain the sizing material extrusion of swelling agent and be fitted on the tissue layer 3 of finishing gluing, drying glue operation, can on described tissue layer 3, be combined into a coating layer 4.Utilize 8 pairs of described coating layer 4 heating of a heater again, and make described coating layer 4 produce foaming and intumescing, utilize 7 pairs of tissue layer 3 in a roll-in unit and coating layer 4 to carry out roll-in at last again, and utilization is provided with an embossing portion 702 at the outer surface of one of them rolling wheel set 701 of described roll-in unit 7, can extrude lines on described coating layer 4.

Though utilize above-mentioned manufacture method to cooperate above-mentioned equipment can make the synthetic cladding of foaming, but described coating layer 4 is when being subjected to 8 heating of described heater, only can produce physical expansion, the stomatal frequency inequality, and form open pore, thereby cause elasticity, docile property, the pliability of the synthetic cladding of foaming ... also relatively poor etc. rerum natura.

Summary of the invention

The object of the present invention is to provide a kind of easy enforcement and can produce the manufacture method that obtains the synthetic cladding of the good foaming of rerum natura.

The present invention foams and synthesizes the manufacture method of cladding, comprises the following step: (A) matrix of crosslinked foaming moulding, and described matrix has two opposing surfaces, and described two surfaces are laid with decorative pattern and respectively form an epithelium.(B) described matrix is cutd open sheet and forms two embryonic plates, described two embryonic plates respectively have one with its opposing faying face in corresponding surface.(C) faying face with described embryonic plate is cemented on the tissue layer.

Useful effect of the present invention is: described matrix can fully foam, and through after cuing open steps such as sheet, fixed tissue layer, can make synthetic cladding maintain preferable elasticity, docile property, pliability ... etc. rerum natura, and whole manufacture process is simple.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is elaborated.

As shown in Figure 2, the foam preferred embodiment of manufacture method of synthetic cladding of the present invention comprises the following step:

Step 1: cooperate and consult Fig. 3, utilize matrix 10 of a hot-pressing and foaming mould 200 crosslinked foaming moulding, described crosslinked foaming is shaped to a kind of irreversible chemical reaction, can produce the closure pore.Described matrix 10 is made by thermoplasticity elastomeric material (TPE), described thermoplasticity elastomeric material is a thermoplasticity polyamine fat elastomer (TPU), thermoplastic rubber (TPR), polyolefin elastomer (TPO), acrylonitrile-butadiene rubber (Nitrile ButadieneRubber, be called for short NBR), methacrylate-butadiene rubber (MethacrylateButadiene Rubber, be called for short MBR); butadiene-styrene rubber (Styrene Butadiene Rubber; be called for short SBR); ethene-vinyl acetate copolymer (EVA) etc.; described matrix 10 has two opposing surfaces 11, and described two surfaces 11 are laid with decorative pattern 111 and form epithelium 112 (see figure 4)s respectively.

Step 2: cooperate and to consult Fig. 5, described matrix 10 is cutd open sheet, and form two embryonic plates 10 ', described two embryonic plates 10 ' respectively have one with it pairing surperficial 11 opposing faying faces 12.

Step 3: cooperate and consult Fig. 6, described embryonic plate 10 ' is cemented on the tissue layer 20.

Described embryonic plate 10 ' can use viscose to combine with the consolidation style of described tissue layer 20, and described embryonic plate 10 ' is dried operation again with after described tissue layer 20 combines with viscose.

In addition, described embryonic plate 10 ' also can use hot binding with the consolidation style of described tissue layer 20, and as shown in Figure 7, described embryonic plate 10 ' and described tissue layer 20 with hot binding before, earlier between described embryonic plate 10 ' and described tissue layer 20, a binding film 30 identical with described embryonic plate 10 ' rerum natura or energy is compatible is set, when described embryonic plate 10 ' is carried out hot pressing with described tissue layer 20, can make the faying face 12 of described embryonic plate 10 ' and tissue layer 20 produce fixed by described binding film 30.

From the above mentioned, can make the synthetic cladding of a foaming, and described matrix 10 can be laid with decorative pattern 111 and form epithelium 112, so do not need to carry out follow-up surface treatment operation again on described surperficial 11 when utilizing described hot-pressing and foaming mould 200 crosslinked foaming moulding.

Therefore, the present invention utilizes above-mentioned steps one matrix 10 of the complete crosslinked foaming of preparation earlier, and described matrix 10 is again through after cuing open sheet, applying tissue layer 20, still can possess internal porosity density height, stomatal frequency is even, proportion is low characteristic, really can produce preferable elasticity, docile property, pliability after making the synthetic cladding of foaming ... etc. rerum natura, and be applied to suitcase, vamp, clothes, sofa, furniture, sphere ... during Deng daily life article, can make described article have preferable practicality.
