Description

Preparation method and application of water-soluble glycidyl versatate resin
Technical Field
The invention belongs to the technical field of functionalized water-based resin, and particularly relates to a preparation method and application of water-soluble glycidyl versatate resin.
Background
The water-based paint is an important means for reducing PM2.5 due to greenhouse effect, the consumption of the wood lacquer in 2019 all the year around is 170 ten thousand tons, wherein the proportion of the water-based wood lacquer is less than 10%, the average Volatile Organic Compounds (VOC) per ton of 90% solvent wood lacquer accounts for 50-60%, and 80 ten thousand tons of volatile organic compounds are discharged to the atmosphere in the year. Such serious pollution is highly appreciated by the countries, and regulations gradually limit the amount of VOC emissions, and politically encourages support for the progress of coating wateriness. The water-based work of the wood paint is vigorously developed by various domestic paint factories. The traditional oily wood lacquer obtains long-term market recognition by the characteristics of high fullness, high hardness, quick drying and low cost, and the waterborne wood lacquer can be recognized by the market only by achieving the appearance effect of solvent type products, so that the waterborne wood lacquer can be truly replaced, and the waterborne wood lacquer is favored by wide consumers.
The water-borne wood varnish which is commercialized at present comprises water-borne two-component polyurethane varnish consisting of a polyurethane curing agent and a hydroxyl polymer, and single-component varnish consisting of acrylic emulsion and isocyanate dispersion. The water-based two-component polyurethane has the advantages that the comprehensive performance is more acceptable by the market, the appearance effect and the hardness are not inferior to those of a solvent type polyurethane, and the defects of low construction solid content, long curing time, limited organic matters and free isocyanic acid are overcome. The acrylic emulsion and the isocyanate dispersion can not be a substitute of high-grade wood varnish in the true sense on the whole, and have a certain distance in hardness, gloss and medium resistance. The product of the invention is added into a double-curing siloxane waterborne wood varnish, and has the effects of increasing curing property, improving construction solid content, wetting wood surface and blocking the rib expansion phenomenon caused by tannic acid in a system. The wood varnish (see another patent of the invention of the application) is a dual-component water-based wood varnish, the organic volatile content of the product is low, the construction is carried out at high solid content, the varnish film has high gloss, high hardness, good visualization and clearness; the harmful substance is zero, and the paint does not contain isocyanate component, formaldehyde, metal catalyst and free isocyanic acid radical; the product is quick to dry and short in curing period, and can be used after 48 hours. Is a waterborne product of woodenware varnish and home decoration materials.
The protection and decoration of the wood surface are mainly realized by adopting a film coating mode, the wood has wide application, and the coating has large demand and high performance requirement due to diverse textures. Wood aspects include softwood, hardwood; the wood materials have different strength, texture, grease and water absorption, and coating defects such as rib expansion, light loss, whitening, oil return, collapse, cracking and the like are often caused. Because water has extremely strong wettability to wood, the defects of the coating films are further amplified in the process of adopting the water-based wood paint, and the technical difficulty of water-based wood paint is increased. The water-based paint is usually realized by changing the state of the paint and changing the polarity of the paint. The state comprises a water-soluble type, an emulsion type, a suspension type or a mixture of the three types; the polarity includes anion, cation, and non-ion. These water-based methods are more or less limited for wood, and defects such as swelling, oil returning, and collapse occur more frequently.
