Problems solved by technology

[0003] During the production process of shoes, many places such as the sole and the upper need to be bonded with adhesives, but the most easily damaged part of the shoe is the bonded part. Weak bonding and stiff bonding are two of the existing bonding technologies. problem
The existing adhesives effectively solve this problem, and it is difficult to meet two requirements at the same time. In order to solve this problem, the present invention produces a two-component polyurethane adhesive with high flexibility and high bonding strength. In the process of shoe bonding, the requirements of Anzu's flexibility and bonding strength can be met

Abstract

The invention relates to a high-flexibility and high-bonding-strength two-component polyurethane adhesive for shoes and a preparation method and application thereof. According to the specific technical scheme, the adhesive consists of a component A and a component B, wherein the mass ratio of the component A to the component B is 2-4 to 1. The component A is a hydroxyl terminated polyurethane component obtained through reaction of hyperbranched polyester polyol, polyether polyol and hexamethylene isocyanate. The component B is an isocyanate terminated polyurethane component obtained through reaction of castor oil, hyperbranched isocyanate and toluene diisocynate. At least one of the component A and the component B contains nitrile rubber microspheres and / or soccer. The final product is the polyurethane adhesive having excellent flexibility and bonding strength and is suitable for production in shoe industry.

Description

Technical field: [0001] The invention relates to the field of adhesives for shoes, in particular to the field of two-component polyurethane adhesives with high flexibility and high bonding strength. Background technique: [0002] Polyurethane adhesive is a kind of adhesive that is widely used in the prior art and has a wide range of applications. It has excellent low temperature resistance, low curing temperature, good flexibility, impact resistance, and infiltration of materials. Good effect, excellent adhesion, it is commonly used in the field of room temperature bonding. [0003] During the production process of shoes, many places such as the sole and the upper need to be bonded with adhesives, but the most easily damaged part of the shoe is the bonded part. Weak bonding and stiff bonding are two of the existing bonding technologies. problem. The existing adhesives effectively solve this problem, and it is difficult to meet two requirements at the same time. In order to...
