Abstract

The invention discloses a silane-alumina wear-resistant coating on the surface of willow handicrafts, and relates to the technical field of handicrafts. The preparation method comprises the followingsteps: mixing alumina treated by vinyl trimethoxysilane with a 2-acrylamide-2-methylpropanesulfonic acid / epoxy resin solution to obtain a composite solution; under the action of a catalyst, modifyingthe composite solution by 2-methyl-2-acrylic acid-2-isocyanatoethyl ester to obtain a composite material; brushing the composite material on the surface of a willow handicraft; placing the brushed willow artware in a drying chamber, and drying to form a wear-resistant coating on the surface of the willow artware. The wear-resistant coating formed on the surface of the willow handicraft has a lowerfriction coefficient, and better wear resistance.

Description

technical field [0001] The invention belongs to the technical field of handicrafts, in particular to a silane-alumina wear-resistant coating on the surface of willow handicrafts. Background technique [0002] There are many shapes and patterns of wooden handicrafts, beautiful and generous, light in weight, can be placed or hung at will, and the cost is low, so it is more and more popular with consumers. However, due to the wood material of handicrafts, it is easy to absorb water, deform, and get moldy due to moisture. , Breeding bacteria, seriously affecting the consumer experience and limiting the development of wooden handicrafts. [0003] Therefore, in the prior art, various protective treatments are carried out on the surface of wooden handicrafts to improve their surface properties. Among them, coating paint on the surface of wooden handicrafts is one of the more commonly used treatment methods, for example: CN 109536021 A, disclosed in the present invention A wood sur...
