[0014] The invention provides a method for preparing a high temperature resistant high and low cabinet, the preparation method comprising:

[0015] 1) Calcining medical stone, graphite, iron tree and shells to obtain calcined products;

[0016] 2) The process of soaking the calcined product in an acid solution to obtain an activated product;

[0017] 3) Mix styrene-acrylate emulsion, polyvinyl alcohol, propylene glycol, methyl cellulose, lithium titanate, tributyl phosphite, melamine, graphene, water glass, adenosine diphosphate and activator to prepare The process of high temperature resistant coating;

[0018] 4) The process of coating the high temperature resistant paint on the surface of the high and low cabinet body to form a paint layer to obtain a high temperature resistant high and low cabinet.

[0019] In the process 1) of the present invention, the specific conditions of calcination can be selected in a wide range, but in order to further improve the insulation res...

Embodiment 1

[0029] 1) Mix medical stone, graphite, iron tree and shells in a weight ratio of 100:28:85:49, and calcinate at 370°C for 8 hours to obtain a calcined product;

[0030] 2) Soak the calcined product in an acid solution with a pH of 4 at 40°C (the weight ratio of the calcined product to the acid solution is 100:380) for 5 hours to obtain an activated product;

[0031] 3) At 25°C, styrene-acrylate emulsion, polyvinyl alcohol (weight average molecular weight is 4000), propylene glycol, methylcellulose, lithium titanate, tributyl phosphite, melamine, graphene, water glass 1. Adenosine diphosphate and the activator were mixed for 35 minutes according to the weight ratio of 100:88:130:13:6:28:32:10:28:12:30 to prepare a high temperature resistant coating;

[0032] 4) Apply the above-mentioned high-temperature-resistant paint to the surface of the high-low cabinet body to form a paint layer to obtain the high-temperature-resistant high-low cabinet A1.

Embodiment 2

[0034] 1) Mix medical stone, graphite, iron tree and shells in a weight ratio of 100:24:78:45, and calcinate at 350°C for 7 hours to obtain a calcined product;

[0035] 2) Soak the calcined product in an acid solution with a pH of 3 at 35°C (the weight ratio of the calcined product to the acid solution is 100:300) for 4 hours to obtain an activated product;

[0036] 3) At 15°C, styrene-acrylate emulsion, polyvinyl alcohol (weight average molecular weight is 3000), propylene glycol, methylcellulose, lithium titanate, tributyl phosphite, melamine, graphene, water glass 1. Adenosine diphosphate and the activator were mixed for 30 minutes according to the weight ratio of 100:80:100:12:4:24:28:8:22:9:28 to obtain a high temperature resistant coating;

[0037] 4) Apply the above-mentioned high-temperature-resistant paint to the surface of the high-low cabinet body to form a paint layer to obtain a high-temperature-resistant high-low cabinet A2.

Abstract

The invention discloses a high temperature resistant high-low cabinet and a preparation method thereof. The preparation method comprises the following steps: 1) a procedure of calcining medical stone, graphite, sago cycas and shell to prepare a calcined product; 2) a procedure of putting the calcined product into an acid liquor for soaking to prepare an activator; 3) a procedure of mixing styrene-acrylate emulsion, polyvinyl alcohol, propylene glycol, methylcellulose, lithium titanate, tributyl phosphite, melamine, graphene, sodium silicate, adenosine diphosphate with the activator to prepare a high temperature resistant coating; and 4) a procedure of coating the surface of the high-low cabinet with the high temperature resistant coating to form the coating layer so as to produce the high temperature resistant high-low cabinet. The high-low cabinet produced according to the method has excellent high temperature resistant performance.

Description

technical field [0001] The invention relates to a high and low cabinet, in particular to a high temperature resistant high and low cabinet and a preparation method thereof. Background technique [0002] Electrical equipment is a general term for generators, transformers, power lines, circuit breakers and other equipment in the power system. Among them, high and low cabinets are a typical electrical equipment. [0003] In the prior art, in order to prevent the surface of the high and low cabinets from being corroded, paint is generally coated on the surface of the high and low cabinets, and the paint can also function as insulation; however, electrical equipment generally works under high temperature conditions, and the long-term After working for a long time, the paint will show obvious aging phenomenon, which makes it difficult for the paint to play a protective role. Contents of the invention [0004] The object of the present invention is to provide a high temperature...
