Problems solved by technology

The modified raw lacquer overcomes the disadvantages of long drying time of the paint film, poor alkali resistance, poor anti-ultraviolet performance, dark paint color, high viscosity and difficult construction.
However, there is almost no academic research and related reports on the application of modified raw lacquer to wood wax oil, and there is a lack of systematic theoretical research and market gaps.

Abstract

The invention relates to the technical field of wood wax oil, in particular to a preparation method of urushiol-based environment-friendly wood wax oil, which comprises the following raw materials: urushiol modified compound, vegetable oil, aldehyde ketone resin, biological wax, drier, diluent, defoamer, leveling agent and an anti-skinning agent. The urushiol epoxy resin is creatively applied to the wax oil, and the modified epoxy urushiol is bright and clear in color and luster and is subjected to cross-linking reaction with the polymerized tung oil and the hard resin, so that the water resistance of a traditional raw paint film is improved, and the actual problems of insufficient hardness, long drying time, poor adhesive capacity and the like of the traditional wax oil are solved.

Description

technical field [0001] The invention relates to a preparation method of wood wax oil, which belongs to the technical field of wood wax oil preparation. Background technique [0002] Wood wax oil is composed of natural vegetable oil and vegetable wax as the base material. It does not use any chemical solvents and is a natural and environmentally friendly paint that does not produce any harmful gases. Wood wax oil has good compatibility with wood and has good permeability to wood. While protecting, moisturizing and decorating, it can fully reflect the natural texture and texture of wood itself. With the continuous deepening of the concept of green environmental protection, it is the general trend to replace traditional solvent-based coatings with environmentally friendly coatings. Wood wax oil obviously has great market prospects and competitive advantages. [0003] The king of coatings, "Lifetime lacquer" is the earliest natural resin used by human beings, and it is also a c...
