Description

technical field

[0001] The invention relates to the field of powder coatings, in particular to a microbubble elastic polyurethane waterproof coating. Background technique

[0002] Powder coating is a new type of solvent-free 100% solid powder coating. It has the characteristics of no solvent, no pollution, recyclable, environmental protection, saving energy and resources, reducing labor intensity and high mechanical strength of the coating film. In the prior art, its powder coating is composed of polyester resin, blocked isophor copper diisocyanate, benzoin and dibutyltin dilaurate. Its disadvantages are poor physical properties, poor covering effect, and easy generation of fine bubbles. Unable to meet electrical spraying and surface protection. That is, the existing powder coatings have poor coverage and cannot meet the needs of production and life. Contents of the invention

[0003] The technical problem to be solved by the present invention is to overcome the above-m...
