Abstract

The invention provides aqueous wood wax oil as well as a preparation method and application thereof, relating to the technical field of coatings. The aqueous wood wax oil is prepared by taking a natural wood wax emulsion and a polyurethane modified acrylic emulsion as main raw materials and adding lignocelluloses and nano silicon sol in a compounding manner, the lignocelluloses can infiltrate into a filming substance to form a staggered net-shaped structure, the nano silicon sol enters gaps among the lignocelluloses, the raw materials act together to form a dense three-dimensional net-shaped structure, then a formed coating film is good in hardness, air permeability, toughness and impact resistance, and the defects that aqueous wood wax oil is poor in air permeability, easy to crack, easy to deform and easy in tendon exposure are alleviated. The invention further provides a preparation method of the aqueous wood wax oil. According to the preparation method, the process is simple, the operation is easy and the industrial production can be realized.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to water-based wood wax oil and its preparation method and application. Background technique [0002] With the improvement of people's living standards, environmental protection, safety and health have increasingly become the focus of people's attention. For home wood furniture, which paint film to choose to decorate and protect it is directly related to people's physical and mental health, and it is also a problem that people often need to face. [0003] At present, the concept of environmental protection and low carbon is deeply rooted in the hearts of the people. The application of organic oil-soluble coatings with high VOC release is more and more restricted, while the environment-friendly water-based coatings with low VOC release are more and more popular and become the mainstream of coating development. trend. Therefore, water-based coatings are increasingly becoming the fi...
