Description

Technical Field

[0001] The invention belongs to the technical field of polymer materials, and in particular relates to a treatment agent for sole rubber materials and a preparation method thereof. Background Art

[0002] In the current shoe manufacturing market, when making soles, the more durable and sturdy solution is to use rubber materials. However, the soles made of pure rubber bottom sheets are relatively hard and not suitable for long-distance treks. Therefore, when making soles, polyurethane or PU glue is usually used to bond the leather upper to the rubber sole. Due to the characteristics of rubber in the rubber sole, grease and rubber additives will penetrate from the surface. If the leather and the rubber sole are directly bonded with polyurethane or PU glue without surface treatment, it is not only difficult but also makes the peeling strength far from enough. Therefore, the rubber sole is often roughened first, and then the leather upper and the rubber sole are bonded with polyurethane or PU glue. However, most of the rubber sheets are uneven, and it is difficult to roughen them; secondly, the roughening process will bring dust and cause air pollution. Therefore, it is imperative to omit the roughening process of the rubber sole.

[0003] At present, the commonly used sole rubber material is symmetrical block styrene butadiene rubber (SBS rubber). In addition to SBS rubber, thermoplastic elastomers (also called thermoplastic rubbers (Thermoplasticrobbers) made of SBS rubber as the main body and other materials are a kind of polymer material that has the characteristics of both rubber and thermoplastic plastics, showing high elasticity of rubber at room temperature and plasticizing and molding at high temperature. It is also the so-called third generation of rubber after natural rubber and synthetic rubber, abbreviated as TPR. Because TPR is wear-resistant, easy to process and low in price, it is widely used as sole materials, especially mid- and high-end sports shoe sole materials.

[0004] When making soles, polyurethane or PU glue is usually used to bond leather uppers to SBS rubber or TPR rubber. Since SBS rubber or TPR rubber has weak polarity, in the cold-bonded shoemaking industry, in order to improve the bonding strength between SBS rubber or TPR rubber and polyurethane or PU glue, it is often necessary to surface treat the SBS rubber or TPR rubber. The surface treatment method is generally grinding with a grinding wheel to give it a rough surface, or using a surface treatment agent to change the surface state of the sole material, or both are performed at the same time to achieve a good bonding effect; however, the roughening process will bring dust and cause air pollution. Therefore, it is necessary to prepare a treatment agent that can improve the bonding strength between the sole rubber material and polyurethane or PU glue. Summary of the invention

[0005] The object of the present invention is to provide a treatment agent for sole rubber material and a preparation method thereof, so as to solve the problem of low bonding strength between sole rubber and polyurethane.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0109] The sole rubber (SBS rubber or TPR rubber) was treated with the sole rubber material treatment agent obtained in Examples 1 to 5 and Comparative Examples 1 to 3, and the treated sole rubber was bonded to leather with polyurethane and a peel strength test was performed. The test results are shown in Table 1:

[0111]

[0112] It can be seen from Table 1 that the sole rubber is first treated with the treating agent of the sole rubber material prepared in Examples 1 to 5, and then the treated sole rubber and leather are bonded with polyurethane, which has a higher peel strength, indicating that the bonding strength between the sole rubber treated with the treating agent and the polyurethane is higher.

The results of Comparative Examples 2 and 3 show that when either the rubber grafted ethylene oxide copolymer emulsion or the EO / PO block polyether grafted copolymer emulsion is missing, the peel strength is poor, indicating that the treatment effect is poor.
