Problems solved by technology

[0003] In the prior art, insoles are generally composed of an elastic bottom layer and a cloth surface layer. During production, the elastic bottom layer is first made, and then glue is applied on the surface of the elastic bottom layer to fit the cloth layer, and finally cut and trimmed. Finished products, this process requires glue brushing and bonding, which is prone to uneven glue brushing, and there are many processes, the production efficiency is low, and the bonding quality between the layers of the insole is not high

Abstract

The invention provides a shoe material hot melt adhesive naked film, a sandwich insole applying the same, and a manufacturing method of the sandwich insole. The shoe material hot melt adhesive naked film is prepared from the following raw material formula: 95.9-99.2 Phr of a TPU main ingredient, 0-0.5 Phr of a slipping agent, 0-0.5 Phr of an anti-blocking agent, 0.1-0.5 Phr of an antioxidant, 0.5-2 Phr of a nucleating agent, 0.1-0.3 Phr of an ultraviolet light absorber, and 0.1-0.3 Phr of a radical scavenger, wherein a thermoplastic polyurethane elastomer serves as the TPU main ingredient. Theshoe material hot melt adhesive naked film has the characteristic of low-temperature fast forming, and can be simultaneously bonded with EVA and PU, thus the sandwich insole applying the shoe material hot melt adhesive naked film is firmer in structure, a memory sponge is used as a middle layer, and thus the insole is more comfortable and more durable.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a shoe material hot-melt adhesive bare film, a sandwich insole using the same and a manufacturing method. Background technique [0002] The name of TPU is thermoplastic polyurethane elastomer. It is mainly divided into polyester type and polyether type. It has a wide range of hardness, wear resistance, oil resistance, transparency and good elasticity. It is widely used in daily necessities, sporting goods, toys, decorative materials and other fields. TPU film has the characteristics of good toughness, high strength, odorless, non-toxic, and heat-sealing processing. [0003] In the prior art, insoles are generally composed of an elastic bottom layer and a cloth surface layer. During production, the elastic bottom layer is first made, and then glue is applied on the surface of the elastic bottom layer to fit the cloth layer, and finally cut and trimmed. Finished products, th...
