Abstract

The invention discloses a preparation method of a low-temperature-resistant snow shoe adhesive, wherein the preparation method is simple in process and convenient in operation. The prepared snow shoeadhesive has high adhesion strength, and after low-temperature treatment, the loss rate of the adhesion strength is no more than 1%, the low-temperature resistance performance is good, and the adhesive is suitable for application in snow shoes. Nano-alumina is subjected to activation treatment, and the activity of the nano-alumina is enhanced, so the nano-alumina is easily combined with dry oxhidegelatin powder, the dispersibility and interfacial compatibility of the nano-alumina in an adhesive base are improved, the interfacial force is enhanced, and thus the bonding strength of the adhesiveis enhanced; on the other hand, with the synergistic effect of the dry oxhide gelatin powder and the nano-alumina, the brittleness is improved and the low temperature resistance of the adhesive is increased; polyimide fibers are modified with a modification liquid, the agglomeration phenomenon of the fibers is improved, the mechanical properties of the fibers are enhanced, the binding force between the polyimide fibers and the adhesive resin base is improved, and the bonding strength and low temperature resistance are further improved.

Description

technical field [0001] The invention belongs to the technical field of adhesives, in particular to a method for preparing an adhesive for low-temperature-resistant snowshoes. Background technique [0002] Shoes are indispensable daily necessities in human production and life. In the process of social development, due to the increasing number of materials, styles and uses of shoes, the types of shoes have also begun to enrich, but adhesives are indispensable for shoemaking. , The choice of adhesive often becomes a key factor in the quality of shoes. Nowadays, snowshoes have become the most popular tool for walking in the snow in winter. Due to the cold weather in winter and the low temperature outside, traditional snowshoes are prone to degumming and cracking when used outdoors and in the snow for a long time. , affecting its quality and service life. Contents of the invention [0003] In view of the above problems, the present invention aims to provide a method for prepa...
