Abstract

The present invention relates to a method for preparing a water-based environmentally friendly anti-scratch coating made of recyclable materials. The specific steps are: (1) adding a certain amount of ethanol extracted from plants to the silica sol liquid, and stirring to obtain a product 1; (2) drop at least one but not limited to one siloxane coupling agent into 1, carry out reaction sol gel reaction, obtain product 2; (3) add natural vegetable oleic acid in product 2 and it Reaction to obtain product 3; (4) adding ammonia water to product 3 to generate water-soluble resin, and reacting to obtain product 4; (5) adding water to the product to obtain water-based resin 5; (6) taking water-soluble resin 5 and adding titanium dioxide inorganic powder Pigments or inorganic pigments of other colors and ethanol solvent are mixed into a paste 6; (7) the material 6 is dispersed to form a flow colloid 7 with a uniform particle size; (8) deionized water is added to the flow colloid 7 to make a water-based environmental protection Scratch resistant coating.

Description

【Technical field】 [0001] The invention relates to the technical field of water-based environmental protection coatings, in particular to a preparation method of water-based environmental protection anti-scratch coatings made of recyclable materials. 【Background technique】 [0002] Commonly used water-based coatings are mainly water-based organic resins as film-forming substances, and their hardness is generally low. Water-based ceramic coatings have high hardness, but construction is inconvenient. Combining organic and inorganic resins through a certain method, the new resin is not only convenient for construction, but also has the high hardness of inorganic resins, and further prepares an environmentally friendly and scratch-resistant water-based coating. [0003] At present, the performance of water-based environmental protection coatings is still far behind that of oil-based coatings. The development of water-based paints still has great constraints. The present inventi...
