Abstract

The invention relates to universal water-based aluminum profile stoving varnish. The universal water-based aluminum profile stoving varnish is prepared from the following materials in percentage by weight: 55-65% of a water-based fluorocarbon emulsion; 10-15% of Allnex 303; 0.1-0.3% of BYK024; 0.1-0.3% of DEGO810w; 0.1-0.3% of BYK346; 0.1-0.3% of EFKA3772; 5-15% of water-based aluminum paste; 1-3%of BYK8421; 12-20% of deionized water; and 0.1-0.3% of RHEOLATE299. According to the technical scheme, the universal water-based aluminum profile stoving varnish is extremely low in VOC content and very good in paint film leveling property, can meet requirements in conventional properties of the paint such as the hardness and the adhesive force, is excellent in water resistance, salt spray resistance, acid and alkali resistance, corrosion resistance and weather resistance, and is high in indoor and outdoor universality.

Description

technical field [0001] The invention relates to a general water-based baking varnish for aluminum profiles and a preparation method thereof. Background technique [0002] Aluminum profile coating pursues paint film decoration and outdoor weather resistance. As a high-end and environmentally friendly coating, water-based aluminum profile baking varnish is increasingly favored by consumers. Existing baking paints for aluminum profiles generally have high voc content and poor weather resistance. Facing the pressure of environmental protection and the requirements of weather resistance, traditional paints and ordinary water-based paints cannot meet market demand. Contents of the invention [0003] Based on the above problems, the present invention provides a paint film with ultra-low VOC content, excellent leveling of the paint film, its hardness, adhesion and other conventional properties meet the requirements, excellent water resistance, salt spray resistance and acid and al...
