High-strength waterborne wood coating and manufacturing method thereof

Abstract

The invention discloses a high-strength waterborne wood coating and a manufacturing method thereof. The high-strength waterborne wood coating is prepared by taking polyurethane acrylate grafted acrylate, starch grafted sodium acrylate, water-soluble alkali, aluminum borate whisker, silicon carbide powder, CF (carbon fiber), tackifier extracted from cornu gorais powder, blocked isocyanate, polyether-siloxane copolymer, and aqueous adhesion promoter as raw materials and deionized water as medium for sufficient reaction at 70-85 DEG C, wherein the tackifier is prepared through the steps of moisturizing, pelletizing, boiling, purifying and concentrating; the waterborne adhesion promoter is prepared through the steps of soaking, microorganism fragmentation, collagen releasing and activating, and concentrating. The high-strength waterborne wood coating has the technical advantages of being applicable to wood surface, waterborne, free from damage to wood, high in strength and wearing resistance, lubricant in surface and good in texture.

Description

technical field [0001] The invention relates to the field of wood coatings, in particular to a high-strength water-based wood coating and a manufacturing method thereof. Background technique [0002] At present, wooden utensils are common in our lives, and their surface paints have great limitations: they are easy to age and peel off, and most of them are organic polymers with high formaldehyde content. Looking at the entire domestic wood utensils market, there are many varieties, but Most of them have the functions of protection, sealing and decoration. Most of the functional coatings are coatings with water resistance, alkali resistance, stain resistance and relatively simple flame retardancy, and most of them are organic-based coatings, which contain harmful substances. components; a small amount of water-based paint has obvious defects such as poor sealing ability or poor bonding with wood. [0003] At present, in the conventional technology in this field, persulfate or...

[0002] At present, wooden utensils are common in our lives, and their surface paints have great limitations: they are easy to age and peel off, and most of them are organic polymers with high formaldehyde content. Looking at the entire domestic wood utensils market, there are many varieties, but Most of them have the functions of protection, sealing and decoration. Most of the functional coatings are coatings with water resistance, alkali resistance, stain resistance and relatively simple flame retardancy, and most of them are organic-based coatings, which contain harmful substances. components; a small amount of water-based paint has obvious defects such as poor sealing ability or poor bonding with wood

[0004] Among the relevant patents that have been applied in China, the patent "A Waterborne Acrylic Wood Sealing Coating and Preparation Method of Its Special Emulsion" (application number: 201010159689.4, publication date: 2010.09.01) discloses an acrylic paint for wood sealing. The copolymer emulsion of the present invention has excellent sealing performance, but without the addition of reinforcing functional substances, its binding force is poor, and it is also easy to be worn and peeled; in addition, other main material components of the invention are prone to produce toxic and harmful substances at high temperatures

The patent "Water-based Wood Lacquer Emulsion" (application number: 200810081974.1, publication date: 2009.09.09) discloses a high-temperature-resistant and water-resistant emulsion, which obtains stable silicon-oxygen bonds by adding silica sol, thereby improving the high-temperature resistance of the emulsion performance, but it has high solid content and is easy to crack; at the same time, there is no additive with adhesion promotion function, and the binding force is poor
