Wear-resistant coating and polyurethane wear-resistant adhesive tape for automobiles based on it

Abstract

The invention relates to a wear-resistant coating and an automobile polyurethane wear-resistant adhesive tape based on the same. The wear-resistant coating provided by the invention comprises, by weight, 10-20 parts of thermoplastic polyester elastomer with shore D hardness of 40-60 HD, 10-20 parts of short-oil alkyd resin with the fatty acid content of 30-40%, 1-5 parts of PBT resin with the meltindex of 30-45 g / 10 min under the condition of 250 DEG C * 2.16 k, 15-35 parts of ceramic powder comprising first ceramic powder with the particle size of 10-100 nm and second ceramic powder with theparticle size of 500-1000 nm, metal nano-powder with the particle size of 20-50 nm, 5-15 parts of an auxiliary agent and 40-60 parts of an organic solvent.

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:
