Preparation process of clay sealant suitable for buried cabinet of transformer substation

Abstract

The invention discloses a preparation process of a clay sealant suitable for a buried cabinet of a transformer substation. The clay sealant comprises the following raw materials: limestone, tackifyingresin, magnesium hydroxide, a nitrogen-phosphorus-boron flame retardant, a plasticizer, chlorinated paraffin and expanded graphite. According to the invention, the added magnesium hydroxide, the nitrogen-phosphorus-boron flame retardant and the chlorinated paraffin are all have flame retardance characteristic; when a mounting gap of the buried cabinet is filled with the clay sealant, fire spreading or huge damage to a filling structure can be prevented when the interior of the cabinet is on fire; the chlorinated paraffin designed by the invention has good electric insulativity, can resist electric arcs generated by electricity leaked from the cabinet, reduces the probability of fire disasters, and improves the safety of the cabinet; and the tackifying resin and the plasticizer designed inthe invention are matched with each other, so the clay sealant is allowed to have good viscosity and is not prone to falling off after gaps are filled, and the use reliability of the clay sealant isguaranteed.

Description

technical field [0001] The invention discloses a preparation process of sealing glue suitable for substation underground cabinets, and belongs to the technical field of building material preparation. Background technique [0002] Sealing cement is a material commonly used in construction to fill gaps. In addition to sealing, it can also play a role in fire prevention, electricity prevention, waterproofing, etc. according to the environment, and protect the objects it seals. [0003] In the prior art, the sealing of substation's underground cabinets is mostly done with conventional sealing cement, and its waterproof, fireproof and other performances are relatively basic, which cannot meet the different needs of substations with different specifications, and there is no such thing on the market. There are technical deficiencies in the sealing cement specially designed for the substation environment. Contents of the invention [0004] The technical problem to be solved by th...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the fact that most of the existing saikosaponins have low purity, and their preparation has more residual impurities, and some impurities are ignored in the process of extraction, resulting in a large amount of saikosaponins on the market. Most of them fail to give full play to their effects, and a preparation process of sealing cement suitable for substation underground cabinets is provided to solve the above problems
