Problems solved by technology

[0002] Traditional plastics use pure calcium aluminate cement as hardening accelerator, with moderate hardening time and good hardening effect, but the introduction of pure calcium aluminate cement also introduces other eutectic phases, which reduces the high temperature performance of plastics; To change the disadvantage of hardening of pure calcium aluminate cement, researchers use the excellent high-temperature performance of MgO to introduce magnesia as a hardening agent to improve the high-temperature performance of plastics. However, the reaction speed of magnesia as a hardening accelerator is too fast, and it is difficult to control hardening Time, bad construction, high scrap rate, increased cost

Description

technical field [0001] The invention relates to a plastic, in particular to a highly wear-resistant plastic for the electric power industry. Background technique [0002] Traditionally, pure calcium aluminate cement is used as a hardening accelerator for plastics. The hardening time is moderate and the hardening effect is good. However, when pure calcium aluminate cement is introduced, other eutectic phases are also introduced, which reduces the high temperature performance of plastics. To change the disadvantage of pure calcium aluminate cement in promoting hardening, researchers use the excellent high-temperature performance of MgO to introduce magnesia as a hardening agent to improve the high-temperature performance of plastics. However, the reaction speed of magnesia as a hardening accelerator is too fast, and it is difficult to control hardening Time, bad construction, high scrap rate, increased cost. Contents of the invention [0003] The technical problem to be sol...
