Abstract

The invention discloses a powder paint for cast iron pumps, which is prepared from the following raw materials in parts by weight: 40-50 parts of bisphenol A epoxy resin, 10-15 parts of silicon nitride, 10-15 parts of mica powder, 2-4 parts of nano carbon fiber, 3-5 parts of ethylene-acrylonitrile copolymer, 1-2 parts of zirconium sol, 3-5 parts of aluminasol, 1-2 parts of polyethylene wax, 3-5 parts of water-based polyurethane emulsion, 3-5 parts of phenol curing agent, 0.1-0.2 part of benzotriazole and 3-5 parts of film forming assistant. The powder paint has excellent cavitation resistance and abrasion resistance. The formed coating has the advantages of high combining capacity with the metal matrix, and low tendency to peeling and cracking, has the advantages of excellent hardness, excellent wear resistance and favorable corrosion resistance, and is suitable for surface protection of cast iron pumps.

Description

technical field [0001] The invention relates to the technical field of powder coatings, in particular to a powder coating for cast iron pumps and a preparation method thereof. Background technique [0002] Pump is a kind of general-purpose machinery with various types and huge quantity, and it is widely used in electric power, water conservancy and other fields. The pump body bears the impact of high-speed airflow and liquid droplets for a long time during operation, and the pump body itself has poor cavitation and abrasion resistance, which greatly affects the operation stability and working life of the pump. Coating protection with paint is a common means of surface protection for pump bodies. As a new type of solvent-free coating, powder coating has the characteristics of no solvent, no pollution, environmental protection, simple coating process, and its excellent coating performance is widely used. However, the coatings formed by the existing powder coatings have poor ...
