Description
Technical Field
The invention provides a two-component matte water-scraping-resistant coating with an orange-peel texture effect, and belongs to an environment-friendly water-based coating in the field of surface decoration.
Background
The types of coatings on the market are mainly classified into 2 types, water-based coatings and solvent-based coatings (oil-based coatings). The solvent-based paint has low requirements on brushing conditions and can be constructed in a wider temperature and humidity range. The solvent-based paint has good leveling property, smooth paint film and less brushing lines or rolling lines. The solvent-based paint has strong surface permeability, and particularly can increase the adhesive force and the surface protection capability of outdoor wood; the smooth surface has better adhesion of the oily paint; the solvent-based paint has bright and attractive luster. However, with the implementation of a new environmental protection method and the collection of paint consumption tax, the traditional solvent type woodenware metal paint does not lack the phenomenon that toxic and harmful substances such as mercury, lead, cadmium and the like, formaldehyde and benzene are seriously overproof, and VOC is also seriously overproof. Therefore, the application of water-based paint is more and more extensive due to the green health aspect. The main application trend at present is that the water-based paint is used on the decoration of metal products, engineering machinery and furniture, and the solvent-based paint is mainly used for the decoration of the outer wall surface of buildings in occasions with lower safety requirements.
Meanwhile, along with the continuous improvement of the living standard of people, the aesthetic requirement is higher and higher, the requirement on the coating is not only limited to good performance, but also has great importance on appearance and ornamental value, and the water-based two-component orange-peel finish not only has the effects of high gloss and high fullness, but also has a special orange-peel effect on the surface of the coating, looks beautiful and is anti-skid; the water-based orange-peel paint can be widely applied to the fields of metal preparation, engineering machinery and plastic paint decoration, such as excavators, detection equipment, agricultural machines, bicycles, toys and the like, and can be customized according to the liking of consumers. However, the existing orange-peel paint is a solvent-based paint, but the application range of the water-based orange-peel paint is wider and the water-based orange-peel paint has higher value due to the consideration of environmental protection and safety. But no perfect water orange-peel paint exists in the current market mainly because of the restriction of related technical problems, firstly, water paint is emerging, no perfect water formula exists, secondly, no proper water orange-peel resin, water scratch-resistant curing agent and orange-peel auxiliary agent (the surface effect is not good, the performance is not good or the intermiscibility is not good)
