Abstract

The invention discloses a micro-foam elastic polyurethane waterproof coating material, which comprises, by weight, 90-110 parts of high-activity mixed polyether, 20-30 parts of polyisocyanate, 2-4 parts of an antioxidant, 0.8-1.2 parts of a foam stabilizer, 75-110 parts of a filler, and 1-5 parts of water. According to the present invention, the cost of the micro-foam elastic polyurethane waterproof coating material prepared according to the formula is reduced compared to the existing coating material, the whole film layer is stable after the product is subjected to spray coating molding, andthe micro-foam elastic polyurethane waterproof coating material has good use prospect.

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...
