Problems solved by technology

[0002] At present, most of the midsole boards on the soles are made of glued pulp boards. Although they have a certain degree of air permeability, they still cannot meet the requirements for air permeability when worn in shoes, and the adhesive strength of the pulp board itself is relatively low. Poor, easily deformed by moisture, making people's feet feel uncomfortable
In recent years, midsole boards made of non-woven fabrics containing glue have appeared. Most of the adhesives used in their preparation are styrene-acrylic resin glues. The bonding strength is greatly improved. Poor performance and poor bonding fastness to shoe soleplate
There are also water-soluble amino resins used as adhesives for midsoles of shoe materials, but there is a problem that formaldehyde exceeds the standard and the shoe materials are not environmentally friendly.

Embodiment 1

[0017] Embodiment 1: a kind of environment-friendly resin adhesive specially used for the mid-sole plate of a new type of shoe material, the proportion of the consumption of its production raw materials can be respectively:

[0018] Self-crosslinking styrene-acrylic emulsion 10%-40%, water-based polyester 30%-80%, epoxy resin emulsion 5%-15%, anti-yellowing agent 0.5%-3%, bactericide. 0.05%-0.5%.

[0019] The self-crosslinking styrene-acrylic emulsion is made of styrene, butyl acrylate, hydroxyethyl acrylate, methylol acrylamide and other monomers.

[0020] The self-crosslinking styrene-acrylic emulsion in this embodiment can be prepared by semi-continuous emulsion polymerization of various monomers such as styrene, butyl acrylate, hydroxyethyl acrylate, and methylol acrylamide.

[0021] The glass transition temperature of the self-crosslinking styrene-acrylic emulsion in this embodiment is controlled at 35°C-50°C, the amount of self-crosslinking functional monomer methylol a...

Embodiment 2

[0032] Embodiment 2: the resin adhesive for sole mid-sole plate in the present embodiment is specifically:

[0033] 250g of self-crosslinking styrene-acrylic emulsion, 650g of water-based polyester solution, 100g of water-based epoxy resin emulsion, 20g of anti-yellowing agent and 1g of Kasson preservative can be combined to obtain a shoe material midsole with a solid content of 35.6%. glue.

[0034] The aqueous polyester solution is prepared by dissolving the aqueous polyester in hot water to obtain an aqueous polyester solution with a solid content of 30%.

[0035] In this embodiment, the water-based epoxy resin emulsion used is the water-based epoxy resin emulsion GEM02 of Shanghai Lvjia Waterborne Paint Co., Ltd.; the anti-thermal yellowing agent is TF-621, an anti-thermal yellowing agent produced by chemical transfer; Pine preservative BAC-81D.

[0036] Compared with the widely used styrene-acrylic emulsion on the market, the mid-sole plate of the shoe material non-wove...

Abstract

The invention discloses a novel environment-friendly resin adhesive special for a shoe material midsole plate. The novel environment-friendly resin adhesive is prepared from the following raw materials: a self-crosslinking styrene-acrylic emulsion, waterborne polyester, an epoxy resin emulsion, a heat-resistant yellowing agent and a bactericide. According to the invention, the self-crosslinking acrylic emulsion, the waterborne polyester, the epoxy resin emulsion and the like are innovatively compounded to prepare the resin adhesive for the middle bottom plate, so that the prepared adhesive not only can remarkably improve the bonding fastness and the stiffening effect, but also can improve the water resistance of the adhesive by reducing and controlling the water absorption rate of a polymer film, so that the service life of the adhesive is prolonged. And the heat-yellowing-resistant agent added in the raw material system for preparing the adhesive can effectively solve the problem of high-temperature yellowing of the polymer film.

Description

technical field [0001] The invention relates to the technical field of shoe materials, in particular to a new type of environment-friendly resin adhesive for mid-sole plates of shoe materials. Background technique [0002] At present, the mid-sole plate on most soles is made of glue-containing pulp board. Although it has a certain degree of air permeability, it still cannot meet the requirements for air permeability when worn in shoes, and the adhesive strength of the glue-containing pulp board itself is relatively high. Poor, easy to deform when wet, making people feel uncomfortable. In recent years, there have been mid-sole plates made of non-woven fabrics containing glue. Most of the adhesives used in their preparation are styrene-acrylic resin glue, which greatly improves the bonding strength and is not easily deformed or corroded by moisture, but there is still air permeability. Poor performance and poor bonding fastness with the sole plate of the shoe material. Water...
