Problems solved by technology

At present, there are many domestic manufacturers of FRP gas pipes, but most of the FRP gas pipes produced have the disadvantage of poor mechanical properties. The poor mechanical properties of gas pipes are due to the mechanical properties of the flame-retardant and antistatic unsaturated polyester resin used to manufacture gas pipes. The decline is caused by the fact that unsaturated polyester resin itself does not have flame retardant and antistatic properties. Therefore, methods of adding flame retardants and antistatic agents are generally used to make unsaturated polyester resins obtain flame retardant and antistatic properties , however, the mechanical properties of its unsaturated polyester resin products are greatly reduced when the additives are added
The main reasons for the decline in mechanical properties are: 1. In order to meet the requirements stipulated in the Ministry of Coal Industry Standard "Code for Safety Performance Inspection of Plastic Pipes Used in Underground Coal Mine" (MT 181-88), the addition of flame retardants and antistatic agents is relatively large. It affects the mechanical and physical properties of FRP products; 2. Some flame retardants and antistatic agents have certain polymerization inhibition effects, making it difficult for the curing degree of unsaturated polyester resin to meet the requirements, which affects the mechanical properties of FRP products
The decline in the mechanical properties of the product makes it easy to cause accidents during the use of FRP pipes used in coal mines. For example, due to the decline in the ability of FRP gas drainage pipes to withstand negative pressure, it is easy to damage the pipe wall structure, resulting in serious consequences such as rupture and damage of the pipes. The effect of gas drainage

Description

technical field [0001] The invention belongs to the field of macromolecule chemical industry, and in particular relates to a flame-retardant and antistatic unsaturated polyester resin prepared by adding additives, which is suitable for manufacturing glass fiber reinforced plastic gas pipes for underground coal mines. Background technique [0002] Flame retardant and antistatic unsaturated polyester resin is the main raw material for manufacturing FRP gas pipes for underground coal mines. The flame retardant and antistatic properties of FRP gas pipes are all obtained from the cured flame retardant and antistatic unsaturated polyester resin. At present, there are many domestic manufacturers of FRP gas pipes, but most of the FRP gas pipes produced have the disadvantage of poor mechanical properties. The poor mechanical properties of gas pipes are due to the mechanical properties of the flame-retardant and antistatic unsaturated polyester resin used to manufacture gas pipes. The...
