Description
Technical Field
The invention relates to the technical field of coatings, in particular to a device and a method for preparing UV (ultraviolet) curing wood wax oil and application thereof.
Background
The wood wax oil has the advantages of strong penetrability, moisture resistance, corrosion resistance, insect resistance, flame retardance, ultraviolet resistance, no generation of any harmful smell and the like. The wood product after wood wax oil coating treatment has clear and natural appearance texture, good hand feeling, no film on the surface, reduced shrinkage and expansion, no bursting, no warping, no falling off and simple and convenient operation. Compared with water paint, the wood wax oil contains less solvent and auxiliary agent, has no formaldehyde, benzene and other harmful substances, is suitable for various weather conditions such as drying, wetting, high temperature, low temperature and the like, and is an ideal product for indoor and outdoor decoration.
The wood wax oil mainly comprises drying oil and semi-drying oil. The iodine value of the drying oil is above 130, the oil is easy to oxidize and dry in air to form flexible solid film with high elasticity, and the coated thin layer can be oxidized and dried in air to form firm film with elasticity, water resistance and no melting and dissolving. The main component is glyceride of unsaturated fatty acid such as linolenic acid, linoleic acid, etc. The oxidized film formed after the semi-drying oil is left for a prolonged period of time is also weak, and still dissolves and is partially soluble. Thus, the drying oil in the wood wax oil is the main component.
Common components in wood wax oil mainly comprise linseed oil, sunflower oil, soybean oil, carnauba wax, beeswax and the like. The linseed oil is also called as linseed oil, and is drying oil obtained by squeezing or extracting the linseed oil. The beeswax has certain softness in oil, can be used for regulating the softness of wood wax oil paint, and can promote the quick compatibility of wax and components.
Most domestic wood wax oil is water-based wood wax oil, still contains benzene and formaldehyde, and has a certain distance from the wood wax oil which is truly environment-friendly. The wood wax oil truly and environment-friendly does not contain formaldehyde, free Toluene Diisocyanate (TDI), harmful metal and volatile organic solvent, is nontoxic and noncorrosive, and is easy to transport, store and construct. In the prior art, no report of a photoinitiator 2959 modified wood wax oil coating is found.

This also corresponds mechanically to the short drying time and stable aging-resistant color differences of wood wax oils. The infrared spectrum of the photoinitiator of example 4 has five main absorption bands in the range of 310-350nm, the electron transition from acyl, the strongest absorption peak occurs at 340nm, which is caused by n→n electron transition from-c=o in carbonyl, carboxyl in the R band, and a red shift occurs.
