Problems solved by technology

However, there are still some problems in the preparation process of nanocomposite functional coatings, such as poor interphase bonding force, poor dispersion of nanofillers, serious agglomeration of inorganic nanomaterials, and poor batch stability. Most of them are still in the stage of laboratory research. No large-scale production
[0003] On the other hand, most of the traditional coating production is carried out by high-speed disperser, sand mill, etc., which is an intermittent operation. The dispersion and sanding time is long, and it is difficult to disperse nano-fillers evenly. At the same time, there are generally low degrees of automation and process efficiency. low energy consumption and high process energy consumption, the batch stability of the produced coating products is not ideal

Description

technical field [0001] The invention belongs to the technical field of paint preparation, and in particular relates to a system and method for continuously preparing organic-inorganic nano-hybrid paint. Background technique [0002] Water-based paints use water as a solvent and are currently one of the safest and most environmentally friendly paints. Due to its own composition and structural characteristics, the coating effect of one-component water-based coatings is not as good as that of oil-based coatings, and there are obvious deficiencies such as low surface hardness, insufficient fullness, and poor water resistance, and the insufficient hardness of water-based coatings has become an important factor in the water-based process of coatings. one of the obstacles. Studies have shown that combining inorganic nanomaterials with water-based coatings is an effective way to improve the hardness of water-based coatings. However, there are still some problems in the preparation...
