Abstract

The invention discloses high-combination-degree environmental endurance type wax oil and a preparation method thereof and belongs to the technical field of coating preparation. The preparation method includes: taking flaxseed shells as a raw material subjected to processes of smashing, extraction, rotary evaporation and the like to obtain crude flaxseed wax; stirring and filtering the crude flaxseed wax subjected to ash removal and normal heptane, collecting filter residues, allowing the filter residues to be mixed with hydrogen peroxide and stand and collecting suspended solids to be dried to obtain refined flaxseed wax; mixing zinc borate, tebuconazole and the like to prepare mildew-proof liquid, and adding the mildew-proof liquid into mixed liquid prepared from tetraethoxysilane and an ethanol solution to obtain compound mildew-proof liquid; heating tung oil, flaxseed oil and castor oil prior to stirring by continuously adding the refined flaxseed wax, carnauba wax and the like, and finally filtering out undissolved substances to be evenly mixed with the compound mildew-proof liquid and the like to obtain the high-combination-degree environmental endurance type wax oil. The prepared wax oil has the advantages of high drying speed, high dry film hardness and good endurance; the combination degree of the wax oil with materials is high, wear resistance is good , and broad application prospect is achieved.

Description

technical field [0001] The invention discloses an environment-friendly and durable wood wax oil with high binding degree and a preparation method thereof, belonging to the technical field of paint preparation. Background technique [0002] Today, people mostly use traditional paints for the current buildings, wooden structures, and indoor and outdoor decorations. Wood cannot breathe, it is easy to crack after a long time, the paint film is easy to fall off, and it is easy to produce yellowing when exposed to sunlight and ultraviolet rays, and its weather resistance and durability are poor. In addition, the raw materials of traditional paints and coatings are mostly chemical products, which contain a large amount of toxic and irritating ingredients, which are harmful to the human body and cannot meet the current people's requirements for health and environmental protection. [0003] Wood wax oil is gradually paid attention to by people as a natural coating. Wood wax oil is a...
