Meanwhile, the soft and hard bonding materials of the first transmission belt 116 are transmitted to the first material transmission roller 323, and the fourth motor 324 drives the second material transmission roller 423, so that the soft and hard bonding materials are transmitted to the next pressing by the second material transmission roller 423.

The second material conveying roller 423 conveys the soft and hard bonding materials to abut against a third transmission belt 421 on the upper pressing plate 411, the fifth motor 422 drives the third transmission belt 421 to convey the soft and hard bonding materials to the lower pressing plate 412, and further drives the second air cylinder 413 to stretch the telescopic rod of the first air cylinder 113 and drive the lower pressing plate 412 to press down to abut against the soft and hard bonding materials, and the telescopic rod of the second air cylinder 413 contracts to realize the pressing process, so that the composite material A is formed. And then the composite material is transmitted to the second material conveying roller 423 through the third transmission belt 421, and the sixth motor 424 drives the second material conveying roller 423, so that the composite material a is transmitted to the edge cutting device 5.

When the composite material a is transmitted to abut against the edge cutting table 511 through the second material transmitting roller 423, the controller 61 is started, the eighth motor 524 drives the fourth transmission belt 523, so that the fourth transmission belt 523 transmits the composite material a to align with the second cutter 514, at this time, the telescopic rod of the third cylinder 513 is expanded and drives the cutter 514 to descend to abut against the composite material a, and the telescopic rod of the second cylinder 413 is contracted to drive the cutter 514 to ascend, so that the edge cutting process is realized, and the composite material B is obtained; at this time, the fourth driving belt 523 conveys the composite material to the third material conveying roller 521, and under the driving action of the eighth motor 524, the third material conveying roller 521 conveys the composite material B to the flanging table 515, so as to facilitate flanging of the soft material in the composite material B, thereby obtaining the soft and hard composite material.

Application example

Application examples 1 to 3

The soft and hard composite material is widely applied in the fields of small household appliances, automobiles, daily necessities and home decoration.

Performance test

Peel strength

The test was carried out according to the national standard GBT2792-1998, 180 DEG Peel Strength test method.

Table 2 experimental data for examples 1-6 and comparative example 1.

It can be seen from the combination of examples 1 to 6 and comparative example 1 and table 2 that the peel strength of comparative example 2 is significantly lower than that of examples 1 to 3, which indicates that the adhesion of the solvent-containing yellow adhesive used in example 1 is lower than that of the moisture-reactive polyurethane adhesives used in examples 1 to 6, and further indicates that the moisture-reactive polyurethane adhesive has good adhesion and can improve the peel strength of the soft-hard composite material because the moisture-reactive polyurethane adhesive has a small shrinkage rate during curing and is not easy to generate.

Comparing and analyzing the example 1 and the example 2, it can be seen that the nylon/polyurethane fabric can be further bonded to a metal better by adding the methylsulfonyl chloride into the moisture-reactive polyurethane adhesive, and the applicant believes that the methylsulfonyl chloride reacts with water at a high temperature to generate acid substances, and the acid substances can react with the metal surface, so that the stress generated in the curing process of the moisture-reactive polyurethane adhesive is small, and the nylon/polyurethane fabric can be well bonded to the metal surface.

Comparing and analyzing the example 3 and the example 4, it can be seen that the bonding property between the polyurethane artificial leather and the plastic plate can be improved to a certain extent by adding the methylsulfonyl chloride into the moisture-reactive polyurethane adhesive. Further comparison with examples 1 and 2 shows that the improvement effect is not better.

Analysis and comparison between the example 5 and the example 6 show that the addition of methylsulfonyl chloride to the moisture-reactive polyurethane adhesive has no obvious effect on the promotion between the polyvinyl chloride artificial leather and the template.
