Abstract

The invention relates to a polycarbonate plate surface treatment process. The polycarbonate plate surface treatment process comprises the following steps: taking a polycarbonate plate, spraying a hardening solution onto the surface of the polycarbonate plate to form a hardening coating, heating the polycarbonate plate at 50-80 DEG C for 2-5 minutes after the spraying, and irradiating the polycarbonate plate with an 800-1000mjUV lamp after the heating to complete the surface treatment process, wherein the hardening coating is a nano wear-resistant graphene crystal coating, and the nano wear-resistant graphene crystal coating comprises the following components in parts by weight: 70-85 parts of polyorganosiloxane resin, 1-20 parts of isopropoxy-ethanol, 1-5 parts of a photoinitiator, 15-20 parts of graphene nano-sheets, 1-5 parts of a dispersant, 1-5 parts of a surfactant, 1-5 parts of a curing agent and 50-60 parts of deionized water. According to the treatment process, a layer of hardening coating is formed on the surface of the polycarbonate plate, so that scratch-resistant and beautiful effects can be achieved, and the polycarbonate plate has a function of a decorative plate andcan replace glass.

Description

technical field [0001] The invention belongs to the technical field of surface treatment of polycarbonate plates, and in particular relates to a surface treatment process of polycarbonate plates. Background technique [0002] Polycarbonate (referred to as PC) is a high molecular polymer containing carbonate groups in the molecular chain. According to the structure of the ester group, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. Among them, the low mechanical properties of aliphatic and aliphatic-aromatic polycarbonates limit their application in engineering plastics. [0003] Polycarbonate sheets have high mechanical strength, extremely high impact toughness, high conversion temperature, and heat resistance without deformation. The working temperature ranges from minus 40°C to 120°C. [0004] Polycarbonate sheets have the advantages of high mechanical strength and good creep resistance, very high impact strength even at low temperatures; r...
