Problems solved by technology

Among them, rattan has high strength and toughness, which is very suitable as a raw material for willow weaving. The skin of rattan has great toughness; rattan willow weaving is a handicraft widely accepted by many people in the market. It has various shapes and functions. It is also very rich. There are not only baskets and fruit baskets for loading things, but also various products for decoration. Many kinds of wicker products are objects that people have close contact with, so they will often touch and produce frequent friction. The adhesion requirements of the surface protective coatings made of rattan and willow have a great test. After frequent contact and friction, the coatings with poor adhesion are prone to cracks and peeling off, thus losing the protective effect

Abstract

The invention discloses high-surface adhesion coating for a rattan wickerwork, and relates to the technical field of wickerwork treatment. The high-surface adhesion coating is prepared from the following components: a silicone-acrylic emulsion, glucosan-modified polyvinyl alcohol, beta-hydroxyalkylamide, a composite filler, an emulsifier and water. The silicon-acrylic emulsion is used as a basic component of the coating; through addition of the beta-hydroxyalkylamide in the coating system, the surface affinity of the prepared coating to the rattan wickerwork can be effectively improved, and the adhesion of the rattan wickerwork to the coating can be improved; through use of the glucosan-modified polyvinyl alcohol, the glucosan-modified polyvinyl alcohol can be chemically bonded with the molecular chain of a film-forming substance which forms the coating in the coating system, so that the structure of the whole coating system is greatly improved; meanwhile, the glucosan-modified polyvinyl alcohol has more significant adsorption, and can greatly improve the surface adhesion of the coating to the rattan wickerwork; through addition of the composite filler, the coating hardness is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of willow weaving, and in particular relates to a coating with high adhesion on the surface of willow weaving made of rattan. Background technique [0002] A vine with tough, extremely long stature. The outer skin of the rattan is smooth in color, smooth to the touch, and has excellent elasticity, which seems contemptuous but not contemptuous. It is also commonly used to weave rattan chairs, rattan boxes and other daily utensils. Among them, rattan has high strength and toughness, which is very suitable as a raw material for willow weaving. The skin of rattan has great toughness; rattan willow weaving is a handicraft widely accepted by many people in the market. It has various shapes and functions. It is also very rich. There are not only baskets and fruit baskets for loading things, but also various products for decoration. Many kinds of wicker products are objects that people have close contact with, so ...
