High adhesion waterborne wood coating and manufacturing method thereof

Abstract

The invention discloses a high adhesion waterborne wood coating and a manufacturing method thereof. The waterborne wood coating takes waterborne acrylic resin, sodium silicate, water-soluble alkali, titanium dioxide powder, activated carbon powder, CNC cellulose nanocrystal, a tackifier extracted from goat horn, blocked isocyanate, a waterborne defoamer, and a waterborne adhesion promoter extracted from peach branches as raw materials, and takes deionized water as a medium to obtain a product through sufficient reaction at 70 DEG C to 85 DEG C; wherein the preparation process of the tackifierincludes infiltration, dicing, braising, purification and concentration; the preparation process of the waterborne adhesion promoter includes foaming, microbial wall breaking, collagen release and activation, and concentration. The high adhesion waterborne wood coating disclosed by the invention has the technical effects of specific application to the surface of woodware, waterborne property, non-injuring to wood, high adhesion, high wear resistance, self-lubricating surface and good texture.

Description

technical field [0001] The invention relates to the field of wood coatings, in particular to a water-based wood coating with high adhesion 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, persulfa...
