Abstract

The invention relates to a protective coating. The protective coating comprises the following components in percentage by weight: 30 to 45 percent of epoxy resin, 1.5 to 3 percent of paraffin, 4.5 to 7 percent of microcrystalline wax, 3.5 to 5 percent of oxidized polyethlene wax, 0.5 to 1 percent of polytetrafluoroethylene micropowder, 25 to 30 percent of epoxy resin diluent, 0.1 to 1 percent of epoxy resin antioxidant, 0.2 to 2 percent of ultraviolet absorbent, 0.1 to 2 percent of accelerator dimethyl phthalate (DMP)-30 and 18 to 25 percent of curing agent. The protective coating which is easy to process and low in cost can prevent illegal advertisements and adhesive paper. The invention also provides a preparation method for the protective coating.

Description

technical field [0001] The invention relates to a protective coating and a preparation method thereof, belonging to the technical field of building exterior wall surface materials. The protective coating is an anti-graffiti and anti-sticking coating applied to the surface of an external wall and has strong solvent scrubbing resistance. Background technique [0002] The poles and walls on both sides of urban roads are not easy to clean or peel off after being polluted by black advertisements and small stickers. Black advertisements can only be covered with ordinary paint, and rough walls are used to prevent small stickers from sticking. The anti-graffiti and anti-stick coatings that have appeared on the market mainly use fluorosilicone resin, fluorocarbon resin or acrylic resin as the main formula and add various additives to achieve low surface energy to achieve related effects. [0003] In the Chinese Patent Application Publication No. CN 101407691A, a patent document call...
