Abstract

The invention discloses a silicone-modified epoxy powder coating, which comprises the following components by weight: 25-30 parts of silicone-modified epoxy resin, 0.5-1.5 parts of dicyandiamide, and 0.1-0.5 parts of amine catalyst 450-540 parts of low-melting point glass powder and 15-30 parts of silica powder. The melting point of low-melting point glass powder is 410-430°C. The silicone-modified epoxy powder coating with the above formula has a lower cost than the existing coating formula, and the overall film layer is stable after the product is sprayed and formed, which has a good application prospect.

Description

technical field [0001] The invention relates to the field of powder coatings, in particular to an organosilicon-modified epoxy powder 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-mentione...
