Abstract

The invention discloses an ultraviolet curing wood coating with a formaldehyde removing function and a preparation method thereof, and belongs to the technical field of composite coating preparation. The preparation method specifically comprises the following steps: 1, mixing maleic anhydride, phthalic anhydride, diethylene glycol and 2, 3-diphosphoglycerate, and reacting at 175-200 DEG C for 7-8 hours to obtain a mixture A; and 2, adding tert-butyl alcohol and tert-butyl acetoacetate into the prepared mixture A, and uniformly stirring at room temperature to obtain the ultraviolet curing wood coating with the formaldehyde removing function. The preparation method is simple, the used raw materials are safe, environment-friendly and harmless to human bodies, and the prepared coating has the advantages of high transparency, good formaldehyde removal effect, high adhesive force, low thermocuring temperature, short thermocuring time and the like.

Description

technical field [0001] The invention belongs to the technical field of composite paint preparation, and in particular relates to an ultraviolet curable wood paint with formaldehyde removal function and its preparation method and application. Background technique [0002] Wooden furniture is used a lot in daily life. With the improvement of living standards, people pay more and more attention to the quality of wooden furniture. In recent years, the release of harmful substances from wood boards and wooden furniture has become the focus of attention, among which the release of formaldehyde is particularly prominent, which has a serious impact on daily life. The main source of formaldehyde in wood boards and wooden furniture is the excessive use of adhesives in wood bonding products, which contain a large amount of formaldehyde, and adhesives must be used during the installation of wooden furniture. At present, the main adhesives in the market are urea-formaldehyde resin, phen...
