preparation example Construction

[0031] The preparation method of the above-mentioned protective coating for outdoor power equipment is as follows: first, mix FEVE fluorocarbon resin, bisphenol A epoxy resin and solvent, add 0.01-0.05 parts by weight of catalyst, and stir and react at 75-80°C for 1-1.2 hours ; Then add modified nano-silica, ultraviolet absorber and remaining catalyst to continue to stir and react for 2-3 hours, and let it cool down naturally.

[0032] Preferably, the stirring speed of the stirring reaction is 200-250 r / min.

[0033] The use method of the protective coating of the present invention is: cleaning the surface of the outdoor electric equipment and then directly painting it, so as to protect the outdoor electric equipment and improve the anti-corrosion and weather resistance performance of the outdoor electric equipment.

Embodiment 1

[0035] A protective coating for outdoor power equipment, made of the following raw materials in parts by weight: 30 parts of FEVE fluorocarbon resin, 12 parts of bisphenol A epoxy resin, 5 parts of modified nano-silica, 25 parts of solvent, and 0.02 parts of catalyst , 0.8 part of ultraviolet absorber.

[0036] The solvent is a composition of methyl oleate and cyclohexanone in a weight ratio of 1.5:1. The catalyst is zirconium acetylacetonate. The ultraviolet absorber is ultraviolet absorber UV-214.

Abstract

The invention provides a protective paint for outdoor power equipment, which belongs to the technical field of paint compositions. A protective coating for outdoor power equipment, made of the following raw materials in parts by weight: 30-45 parts of FEVE fluorocarbon resin, 12-20 parts of bisphenol A epoxy resin, 5-10 parts of modified nano-silica, solvent 25‑35 parts, catalyst 0.02~0.1 part, ultraviolet absorber 0.8~1.5 part. The protective coating for outdoor electric equipment of the present invention can enhance the weather resistance and anticorrosion performance of outdoor electric equipment.

Description

technical field [0001] The invention relates to the technical field of coating compositions, in particular to a protective coating for outdoor power equipment and a preparation method thereof. Background technique [0002] The installation locations of most power equipment in my country are mainly chosen outdoors. In this case, the power equipment is subjected to wind, sun, and other natural environments all year round. The surface is easily corroded, dust and aging, and the probability of accidents is low. become relatively large, so the protection of electrical equipment is very important. [0003] Fluorocarbon coatings have been used in the field of anti-corrosion for a long time. Based on their unique chemical structure, fluorocarbon coatings have special advantages in anti-corrosion of power equipment and its metal structures. The anti-corrosion effect of paint mainly includes the following contents: ① shielding effect ② cathodic protection effect ③ resistance effect of...
