High-temperature adhesive for adhesion of engineer boots and preparation method and application thereof

Abstract

The invention discloses a high-temperature adhesive for adhesion of engineer boots with excellent high temperature resistance and high adhesive strength and provides a preparation method and application thereof. The adhesive comprises 100 weight parts of vulcanized carboxyl butadiene acrylonitrile rubber, 50-80 weight parts of vulcanized acrylic rubber, 30-50 weight parts of thermal conducting filler, 3-8 weight parts of a coupling agent, 2-10 weight parts of an antioxidant and 18-30 weight parts of a tackifier. By selecting the carboxyl butadiene acrylonitrile rubber and acrylic rubber with excellent high thermal property, compounding graphene, carbon nano tubes and spherical aluminum oxide and selecting the tackifier, the high temperature resistance and adhesive strength are balanced, and the high-temperature adhesive for adhesion of engineer boots with excellent high temperature resistance is obtained.

Description

Technical field: [0001] The invention relates to the field of adhesives for shoes, in particular to the field of adhesives for high-temperature engineering bonding. Background technique: [0002] Nitrile rubber and acrylic rubber are two kinds of rubber commonly used in the prior art. They have the characteristics of high temperature resistance, oil resistance, friction resistance and excellent adhesion, and are widely used in various industrial fields. Graphene and carbon nanotubes, as new carbon materials developed in recent years, have high specific surface area, high thermal conductivity, and high temperature resistance, and have become a "new favorite" in the field of heat resistance and heat conduction. However, they are not compatible with matrix resins. Poor compatibility and difficulty in achieving high filling limits its use. [0003] In the process of shoe production, many places such as the sole and the upper need to be bonded with adhesives, but the most easily...

Problems solved by technology

Graphene and carbon nanotubes, as new carbon materials developed in recent years, have high specific surface area, high thermal conductivity, and high temperature resistance, and have become a "new favorite" in the field of heat resistance and heat conduction. However, they are not compatible with matrix resins. Poor compatibility, difficult to achieve high filling content limits its use

[0003] In the process of shoe production, 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 bonding part. Under high temperature conditions, due to the poor heat resistance of the adhesive, the bonding force drops significantly. , common shoe adhesives are difficult to meet the needs of long-term use of high-temperature engineering shoes
