Abstract

The invention relates to fluorocarbon finish and a preparation method thereof. The fluorocarbon finish is prepared from raw materials in parts by weight as follows: 21-24 parts of PVDF (polyvinylidene fluoride) fluorocarbon resin, 20-24 parts of 40% thermoplastic acrylic resin, 13-18 parts of xylene, 8-15 parts of butyl acetate, 20-25 parts of rutile titanium dioxide and 0.5-1 part of a leveling agent. The preparation method comprises the steps as follows: all the PVDF fluorocarbon resin, the 40% thermoplastic acrylic resin and the butyl acetate as well as part of thexylene are added into a mixer firstly to be mixed at the medium speed for a period; the rutile titanium dioxide, the leveling agent and the rest xylene are added at the same rotating speed to be mixed at the high speed for a period; and the mixed materials are grinded. The fluorocarbon finish and the preparation method thereof have the benefits as follows: the method is performed at the normal temperature, convenient, simple and easy to operate; the prepared fluorocarbon finish product is ultrahigh in acid resistance, alkali resistance and weather resistance and easy to maintain and clean.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a fluorocarbon topcoat and a preparation method thereof. Background technique [0002] The topcoat is the key layer of paint spraying, which is to provide the decorative color required by the aluminum, so that the appearance of the aluminum meets the design requirements, and protect the metal surface from the erosion of the external environment, acid rain and pollution, and prevent ultraviolet rays from penetrating. Enhance anti-aging ability. Existing coatings have insufficient performance in terms of acid resistance, alkali resistance and weather resistance. Contents of the invention [0003] The purpose of the present invention is to provide a fluorocarbon topcoat and a preparation method thereof, so as to overcome the above-mentioned deficiencies existing in the prior art. [0004] The purpose of the present invention is to realize through the following technical solutions: [00...
