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] A switch cabinet sealing primer, made of the following raw materials in parts by weight (kg): E-20 epoxy resin 65, tetrakis (2-hydroxyethyl) adipamide 4, tris (2-hydroxyethyl) iso Cyanurate 2, Zinc naphthenate 2, Dimethylsulfoxide 5, Aminomethylamine 6, Lignosulfonate 2, Accelerator TETD 1, Petroleum resin 10, Alkyd resin 58, Xylene 9, Acetic acid Ethyl ester 12, auxiliary agent 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 pulveri...

Abstract

The invention discloses a seal primer for a switch cabinet. The seal primer is prepared from the following raw materials in parts by weight: 65-69 parts of E-20 epoxy resins, 3-4 parts of tetra(2-ethoxyl) adipamide, 2-3 parts of tri(2-ethoxyl) isocyanuric acid, 2-3 parts of zinc naphthenate, 4-5 parts of dimethyl sulfoxide, 6-8 parts of m-amino methylamine, 1-2 parts of lignosulfonate, 1-2 parts of accelerants tetraethylthiuram disulfide (TETD), 10-12 parts of petroleum resins, 58-63 parts of alkyd resins, 7-9 parts of dimethylbenzene, 12-14 parts of ethyl acetate and 3-4 parts of auxiliaries. According to the auxiliaries, the optical performance is improved, so that the oil paint can be uniformly dispersed, the stability of the oil paint is maintained, and the membrane formation effect is improved; and compared with the prior art, the seal primer has the advantages of high anti-alkali and anti-salting performance, high paint adhesion force and high sealing performance.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a switch cabinet sealing primer 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, s...
