Problems solved by technology

However, the coatings formed by the existing powder coatings have poor bonding ability to the metal substrate, are brittle, have poor impact resistance, and are easy to crack, which limits the application of powder coatings in pump surface protection to a certain extent.
Bacteria, mold and other harmful microorganisms grow on the inner surface of the water pump, which is not easy to clean, which not only affects the normal operation of the water pump, but also pollutes the water source

Abstract

The invention discloses an antimicrobial mildewproof powder paint for water pumps, which is prepared from the following raw materials in parts by weight: 40-50 parts of bisphenol A epoxy resin, 15-25 parts of zeolite powder, 10-15 parts of tourmaline powder, 1.5-2.5 parts of nano copper, 1-2 parts of zirconium sol, 3-5 parts of aluminasol, 1-2 parts of konjac glucomannan, 0.5-1 part of glyceryl caprylate-caprate, 3-5 parts of water-based polyurethane emulsion, 3-5 parts of phenol curing agent 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 antimicrobial and mildewproof effects, prevents the bacteria and mildew from generation, and is beneficial to the sanitation of the environment and water bodies.

Description

technical field [0001] The invention relates to the technical field of powder coatings, in particular to an antibacterial and mildew-proof powder coating for water 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 existin...
