Problems solved by technology

[0005] The wear-resistant tapes disclosed above are all provided with a fabric layer and only rely on elastic fibers or elastomers to provide wear resistance, but the preparation of the fabric layer is time-consuming, and the functional substances that provide wear resistance are relatively simple, so it is simple to develop more preparation methods And more wear-resistant tapes that impart wear resistance are necessary

Description

technical field [0001] The invention relates to the field of adhesive tapes for automobiles, in particular to a wear-resistant coating and a polyurethane wear-resistant adhesive tape for automobiles based thereon. Background technique [0002] Tapes are widely used in the automotive industry. In the process of protecting and fixing the surface of automotive parts, users have put forward higher requirements for the properties of tapes such as elasticity, tear resistance, bending resistance and abrasion resistance. [0003] Abrasion resistance is a measure of the strength of the tape against rubbing. A method for determining the abrasion resistance of protective systems in vehicle electrical equipment is established in the international standard ISO 6722. Based on standard ISO 6722, the abrasion resistance of the tape is tested according to LV 312. The currently available wear-resistant tapes are as follows: [0004] CN201811580819.4 discloses a wear-resistant fabric tape. ...
