Wear-resistant anti-sticking coating for food machinery and preparation method of wear-resistant anti-sticking coating

Abstract

The invention provides a wear-resistant anti-sticking coating for food machinery and a preparation method of the wear-resistant anti-sticking coating. The coating is prepared from the following components in parts by weight: 35.6 to 38.5 parts of functional monomer, 1.3 to 1.8 parts of initiator, 4.8 to 6.8 parts of coupling agent, 35.3 to 50.7 parts of film-forming base material, 9.6 to 13.2 parts of additive, 11.7 to 16.6 parts of composite filler, 2.2 to 3.9 parts of defoaming agent, 1.9 to 2.6 parts of antibacterial agent and the balance of deionized water. The hardness and wear resistance of a coating film are improved through the functional monomer modified nanoscale filler, the coating film is endowed with excellent hydrophobic, anti-sticking and antibacterial properties, meanwhile, the compatibility between the filler and a film-forming solvent is greatly improved, and the defects of the coating film are reduced. The finally prepared coating is high in adsorption capacity, good in film-forming property, high in hardness, wear-resistant, anti-sticking, non-toxic, free of volatile matters and suitable for being used as a food mechanical coating.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to high-hardness and wear-resistant coatings for machinery, in particular to a wear-resistant and anti-adhesive coating for food machinery and a preparation method thereof. Background technique [0002] Paint not only has the value of protecting the coated object, but also plays a very good decorative role due to its rich colors. Nowadays, with the continuous improvement of people's awareness of environmental protection, the development of water-based coatings has been vigorously advocated. The solid components in the paint such as pigments and fillers occupy an important part, and their dispersion stability in the water-based system determines the quality of the paint. At the same time, the dispersion stability of the filler and its compatibility with organic solvents There are certain defects, so the high hardness coating film has the problem of poor weather resistance and easy ag...
