Abstract

The invention discloses a manufacturing method of foaming synthetic leather with embossed patterns. First, a base material and a surface material are prepared, wherein the base material possesses a blank plate, and the surface material is film-shaped. The blank plate of the base material and the surface material are compactly combined by a binding agent, and a resulting material is embossed with patterns, such that the foaming synthetic leather with embossed patterns is obtained. The base material of the synthetic leather can be subject to a sufficient cross-linked foaming reaction, such that the base material have high density of internal pores, low specific weight, and low cost. The surface material can obtain a texture similar to that of genuine leather.

Description

The manufacture method of the synthetic embossing cladding of foaming

Technical field

The present invention relates to a kind of manufacture method of the synthetic embossing cladding that foams.

Background technology

Synthetic cladding has been widely used in daily living article, such as suitcase, vamp, clothes, sofa, furniture, sphere ..., the kind of synthetic cladding roughly has polyvinyl chloride (PVC) cladding, polyurethanes (PU) cladding.

The manufacture method of existing a kind of polyurethanes cladding, as shown in Figure 1, it is polyurethanes top layer 102 of coating on a release liners 101, and after a baking box 3 baking dryings, can make a plane materiel 1, in addition, at coating one deck following layer 202 on the base cloth 201 and after the 3 baking low temperature dryings of a baking box, can make a ground 2, again the following layer 202 of half-dried ground 2 is fitted with the top layer 102 of described plane materiel 1, drying, can obtain finished product through maturation, after release.

Though, utilize above-mentioned manufacture method can make the synthetic cladding of polyurethanes, because the cost of polyurethane material is higher, and along with described top layer 102 is thicker, the finished product cost heals expensive and weight more weighs.

The specific embodiment

The present invention is described in detail below in conjunction with drawings and Examples.

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

Step 1: cooperate and consult Fig. 3, prepare a ground 10, described ground 10 has a tissue layer 11 and most the embryonic plates 12 that are cemented on the described tissue layer 11.Described ground 10 has following forming step:

Step 1-1: utilize most matrixes 12 ' of a hot-pressing and foaming mould 200 crosslinked foaming moulding, crosslinked foaming is shaped to a kind of irreversible chemical reaction, can produce the closure pore.The material of described matrix 12 ' is polyolefin elastomer (TPO), and respectively has an end face 121 ', a bottom surface 122 ' and be engaged on described end face 121 ' and four intermarginal sides 123 ' of described 122 ' week of bottom surface.

Step 1-2: described matrix 12 ' is carried out cutting edge, cutting edge is carried out in described side 123 ' to described matrix 12 ', form most clouts 124 ', and the part of the 12 ' cutting edge of the matrix after the cutting edge forms, and majority is individual to have pore and is plane faying face 125 ' with described side 123 '.

Step 1-3: with the 12 ' splicing of the matrix after the cutting edge, and it is fixed to utilize hot melt or gluing mode to give at two relative faying faces 125 ', and is consolidated into an idiosome 12 that extends along a plane P ".

Step 1-4: to described idiosome 12 " cut open sheet and form most in the form of sheets embryonic plate 12 and the clout 13 of two end faces with described matrix 12 ' 121 ' and bottom surface 122 '.

Step 1-5: described embryonic plate 12 is cemented on the described tissue layer 11 with hot melt or gluing mode, can makes described ground 10.

Step 2: as shown in Figure 4, prepare a plane materiel 20, the mode of making of described plane materiel 20 is to make the film shape with polyurethanes (PU) or thermoplasticity polyamine fat elastomer (TPU) plastics.

Step 3: at described ground 10 when throughput direction is carried, to embryonic plate 12 surface coating one deck solids 30 of described ground 10.Preferably, in order to promote then property, embryonic plate 12 surfaces to described ground 10 are coated with rerum natura and polyurethanes or the compatible inorganic agents (Primer) of thermoplasticity polyamine fat elastomer material earlier before coating solid 30.

Step 4: with the described embryonic plate 12 and the described plane materiel 20 relative applyings of described ground 10, when utilizing a pair of rolling to take turns 300 pressings, it is fixed to borrow described solid 30 to produce, and forms semi-finished product.

Step 5: utilize one for example to heat for 400 pairs of described semi-finished product of heating unit of baking oven, and make described solid 30 dryings and described plane materiel 20 is softened, utilize the semi-finished product after the 500 pairs of heating in an embossing unit to carry out embossing again, go out the lines (see figure 5) in described plane materiel 20 surface imprint.

As shown in Figure 5, the synthetic embossing cladding of the foaming of making by above-mentioned steps has described ground 10, described plane materiel 20 and in order to the solid 30 that the embryonic plate 12 of described ground 10 and plane materiel 20 is fixed, and described plane materiel 20 surface pressure are printed on the lines of similar corium.

Therefore, the present invention utilizes above-mentioned steps one matrix 12 ' of the complete crosslinked foaming of preparation earlier, described matrix 12 ' passes through cutting edge again, splice and cut open sheet and become embryonic plate 12, after the tissue layer of fitting again 11, then still possess internal porosity density height, stomatal frequency is even, the characteristic that proportion is low, really can produce preferable elasticity, docile property, pliability ... etc. rerum natura, and the elastomeric cost of polyolefin is low than polyurethanes, it is light that the weight of making finished product is also made finished product than polyurethanes, moreover utilize step 5 that described plane materiel 20 surface imprint are gone out lines, can produce the texture of similar corium again, when the synthetic embossing cladding of foaming is applied to suitcase, vamp, clothes, sofa, furniture, sphere ... Deng the daily life article, can make above-mentioned article reach preferable practicality.

What deserves to be mentioned is that the ground 10 of the above embodiment of the present invention also can only be provided with described embryonic plate 12, and ground 10 forming steps of step 1, also can corresponding step 1-5 be omitted.

Again as shown in Figure 6, the manufacture method and first preferred embodiment of the present invention's second preferred embodiment are roughly the same, difference is in and has mostly to hot-rolling wheel 410 ' in: described heating unit 400 ', also can reach purpose and the effect identical with first preferred embodiment.
