AI Technical Summary

Technical Problem

Existing aluminum profile powder coatings have insufficient adhesion, poor weather resistance, and poor antibacterial properties under temperature variations and humid conditions, making it difficult to meet the long-lasting aesthetic and hygiene requirements of high-end buildings.

Method used

A modified resin base is used to compound bisphenol A type epoxy resin and fluorocarbon resin, and a specific ratio of protocatechuic acid, 2-(4-thiazolyl)benzimidazole and 8-hydroxyquinoline are added as antibacterial agents. Through chemical bonding, combined with the mixing of modified filler and resin matrix, the composition formulation is optimized to improve adhesion and antibacterial performance.

Benefits of technology

It achieves excellent adhesion and weather resistance of aluminum profile coatings, significant antibacterial effect, avoids uneven coating performance and antibacterial agent migration problems, and is suitable for building, medical and home aluminum profiles with high hygiene requirements.

Abstract

The invention discloses an aluminum profile spraying powder coating and a preparation method thereof, and belongs to the technical field of coatings. The modified resin is introduced, so that the coating has excellent weather resistance, protocatechuic acid, 2-(4-thiazolyl) benzimidazole and 8-hydroxyquinoline in a specific proportion are added and compounded to serve as an antibacterial agent, the antibacterial agent is chemically bonded into a resin base material, the efficient, lasting and broad-spectrum antibacterial effect is achieved, the more remarkable antibacterial purpose is achieved, and the coating has the good application prospect. The problems that an antibacterial agent sprayed on the surface is prone to migration and failure are effectively solved. According to the invention, the whole formula is optimized, and the components interact with one another, so that the coating has excellent surface flatness and apparent quality, and the common defects of pinholes and orange peels in the traditional coating are avoided; the antibacterial aluminum profile has remarkable antibacterial property and lasting antibacterial property on the whole, and is particularly suitable for buildings, medical treatment and home furnishing aluminum profiles with high sanitary requirements.
