Background technique

The materials used in the soles of the footwear industry include rubber, EVA and artificial leather, leather and other materials. The surface of the sole is inert. Before the gluing and bonding, it is necessary to align the bonding surface with a treatment agent for surface treatment. Bonding strength is usually surface treated by chemical etching and chemical grafting.

The rubber material is used as the sole of the shoe. The bonding method in the prior art is: cleaning the rubber sole with an alkaline liquid in sequence, neutralizing with an acidic liquid, rinsing with water, then drying the rubber sole, and manually painting The rubber treatment agent is chemically etched, dried, and finally glued. The main component of the rubber treatment agent is a synthetic resin to which an organic solvent is added.

The EVA material is used as the sole of the shoe. The bonding method in the prior art is: cleaning the EVA sole with an alkaline liquid in sequence, neutralizing with an acidic liquid, rinsing with water, drying the EVA sole, and manually painting the EVA. The treatment agent corrodes the EVA sole to produce a rough bonding surface. The main component of the EVA treating agent is a mixture of methyl ethyl ketone, cyclohexanone and methyl carbonate.

Each of the above bonding methods is usually performed manually by a worker and has the following disadvantages:

First, emit a large amount of VOC and industrial wastewater;

Second, the process is complicated, requiring workers to apply reagents on the sole surface, and the labor cost is high;

Third, the energy consumption is large, and the plant space is occupied, resulting in high production costs;

Fourth, VOC emissions are high and toxic, which seriously affects the health of workers on site.
