Thermosetting plastic used for underground installation and preparation method thereof

Abstract

The invention discloses a thermosetting plastic used for underground installations, comprising the following components according to parts by weight: 100 parts of thermosetting resin, 8-12 parts of internal releasing agent, 400-500 parts of inorganic miner filler, 2-4 parts of initiator, 0.4-1.0 part of thickening agent, 10-20 parts of technical accessory ingredient and 220-300 parts of continuous glass fiber. The invention also discloses a preparation method for the thermosetting plastic. The plastic disclosed by the invention can replace materials used for the traditional underground installations, such as concrete, metal materials, thermoplastic plastics and the like, has the characteristics of high strength of concrete and metal material, has the advantages of moisture resistance, corrosion resistance, convenient maintenance and replacement, mildew prevention and low cost of the thermoplastic plastics, also has the advantages of high strength, low water absorption, corrosion resistance, precise size and low calorific power, is convenient to replace and replace, does not collapse during burning, and does not generate toxic smoke.

Description

technical field [0001] The invention relates to the technical field of thermosetting plastics, in particular to a lower calorific thermosetting compound (LCTC for short) for underground facilities and a preparation method thereof. Background technique [0002] After decades of development, thermosetting plastics have become increasingly mature from manufacturing process to application. During the whole development process, traditional materials such as metal and plastic have always faced its challenges. Thermosetting plastics have many characteristics that allow for an optimal combination of overall cost, reliable performance, appearance, safety, ease of maintenance, and the environment. [0003] Compared with metal materials, thermosetting plastics have good design adaptability, including highly intensive parts; high-precision molding tolerances, which can save many mechanical operations, and good surface appearance (including moldable coloring and surface patterns) ; Corr...

AI Technical Summary

Problems solved by technology

[0006] Traditional building materials such as concrete are prone to physical and chemical erosion in the underground humid environment, which affects its durability. In severe cold areas, it is prone to freeze-thaw damage due to the humid environment

Moreover, there are also disadvantages such as inconvenient construction and long construction period in underground facilities.

However, traditional metal materials are more prone to corrosion in humid underground environments, making maintenance difficult and expensive

Although thermoplastics can solve the above-mentioned corrosion problems of concrete and metal materials, they have the following fatal flaws: underground facilities are airtight and poorly ventilated. Once a fire occurs, thermoplastics will burn, producing a large amount of toxic smoke and releasing a large amount of combustion heat. , and melted, structural collapse occurred, which threatened the structure of the underground facility itself and the life safety of the personnel in it, and was not conducive to the stability of the structure of the underground facility and the evacuation and escape of personnel
