Problems solved by technology

The working environment of the switchgear is diverse, and some environments are harsh. It is necessary to coat the surface of the cabinet with a paint layer to resist high temperature, cold, ultraviolet rays, and corrosion. However, the existing paint cannot meet the different requirements of electrical, switch, and instrument cabinets.

Embodiment Construction

[0008] An epoxy metal paint, made from the following raw materials in parts by weight (kg): E20 epoxy resin 62, melamine formaldehyde resin 30, maleic anhydride 6, 1-(vinyloxy)hexadecane 4, cyanuric acid Zinc 3, zinc oxide 3, alum powder 3, catechol 1, zirconium fluoride 4, zinc phosphate 10, dimethylaminopropane 1, mica powder 12, ethyl acetate 12, additive 4;

[0009] The auxiliary agent is made of the following raw materials in parts by weight (kg): attapulgite 100, jade powder 12, sepiolite 20, manganese sulfate 6, zinc oxide 3, zinc sulfate 2, zinc stearate 3, ascorbic acid 1. Angelica oil 0.1, cross-linking agent TAC1; the preparation method is to grind and mix attapulgite, jade powder, sepiolite and manganese sulfate, grind to obtain 200-300 mesh powder, and add stearate to the mixed powder Zinc acid, stir evenly, press into a block at 30-40Mpa, put it into a calciner at 950-980°C, calcinate for 3-4 hours, after cooling, take out and pulverize to obtain a 300-400 mesh p...

Abstract

The invention discloses epoxy resin metallic paint. The epoxy resin metallic paint is characterized by being prepared from the following materials in parts by weight: 62-65 parts of E20 epoxy resin, 30-34 parts of melamine formaldehyde resin, 6-8 parts of maleic anhydride, 4-5 parts of 1-(vinyl oxygroup) hexadecane, 2-3 parts of zinc cyanurate, 3-4 parts of zinc oxide, 2-3 parts of alum powder, 1-2 parts of dimethyl propane, 1-2 parts of catechol, 3-4 parts of zirconium fluoride, 10-12 parts of zinc phosphate, 9-12 parts of mica powder, 12-14 parts of ethyl acetate and 4-5 parts of auxiliaries. According to the invention, the auxiliaries improve optical performances, so that paint is uniformly dispersed, stability of paint is kept, and film-forming effect is improved. According to insulated primer, an appropriate amount of resistant adjusting agent dimethyl propane is added into the formula of the primer, so that resistance value of a paint film formed by the primer is increased, conductive capacity is lowered, and insulated effect is achieved. The epoxy resin metallic paint disclosed by the invention is suitable for being used by an electrical cabinet, and the like.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to an epoxy resin metal paint and a preparation method thereof. Background technique [0002] Electrical, switch, and instrument cabinet (switch cabinet) is a kind of electrical equipment. The outside line first enters the main control switch in the cabinet, and then enters the sub-control switch, and each branch is set according to its needs. Such as instruments, automatic controls, motor magnetic switches, various AC contactors, etc., some also have high-voltage room and low-voltage room switch cabinets, high-voltage busbars, such as power plants, etc. load shedding. The working environment of switchgear is diverse, and some environments are harsh. It is necessary to coat the surface of the cabinet with a paint layer to resist high temperature, cold, ultraviolet rays, and corrosion. However, the existing paint cannot meet the different requirements of electrical, switch...
