Background

The wood wax oil is a common name in China of vegetable oil wax coatings, is a natural wood coating similar to paint and different from the paint, and is prepared by fusing refined linseed oil, palm wax and other natural vegetable oils with vegetable wax and other natural components as raw materials. Therefore, it does not contain toxic components such as triphenyl, formaldehyde, heavy metal and the like, and has no pungent smell. Because the oil in the wood wax oil can permeate into the wood to carry out deep moistening and maintenance on the wood, the wax can be tightly combined with wood fibers to enhance the surface hardness and prevent water and pollution, and the wood wax oil is widely applied to the protection of wooden furniture.

Although wood wax oil has excellent performance and is widely used for protection of wooden furniture, the wood wax oil on the market at present has the following defects which are difficult to avoid:

(1) the wood wax oil is vegetable oil wax, and furniture coated with the wood wax oil sometimes has the phenomena of mildew, white frost and flammability, and can not be used when being frozen in winter.

(2) The main component of the traditional wood wax oil is natural vegetable oil, the unsaturated fatty acid content in the vegetable oil is higher, the saturated fatty acid content is lower, the freezing point is very low, and the wood wax oil is difficult to dry under normal conditions. The drying time is 6-8 hours for almost complete drying, and even the drying can be carried out overnight.

Chinese patent (publication No. CN201810494824.7) relates to an antibacterial wood wax oil for woodware and a preparation method thereof, wherein nano silver ions are used, the nano silver ions are required to be reacted and prepared under the condition of high temperature (70-90 ℃) during preparation, the consumed time is long, the energy utilization consumption is large, the environment is not environment-friendly enough, and the formula and the preparation method of the wood wax oil are greatly different from those of the patent.
