Whether-resisting wood oil and preparation method thereof

Abstract

The present invention discloses a weatherproof wood oil, including tung oil as well as modifier. The tung oil covers 47.5 to 77.5wt percent, modifier 17.5 to 47.5wt percent; the total weight percent of the tung oil and the modifier is not less than 95 percent, and the total percent of water and foreign substances is not bigger than 5 percent. The wood oil becomes dry rapidly after painting, and has better moisture-proofing, fungi-proofing, sun-screening and antibiotic effects, sound desquamation-proofing and ultraviolet-proofing functions. The weatherproof wood oil prepared by the method is characterized by light fragrance and environment-friendly features.

Description

technical field [0001] The invention relates to a wood oil, in particular to a weather-resistant wood oil, which can be painted on wood or wood products for anti-mildew, waterproof, sun-proof, anti-flaking and the like. The invention also relates to a preparation method of weather-resistant wood oil, which is used for preparing the weather-resistant wood oil of the invention. Background technique [0002] Tung oil is a famous specialty product in my country and one of the traditional bulk export commodities. Tung oil is the oil extracted from the seeds of tung oil, a specialty oil tree species in my country. Tung is a genus of Euphorbiaceae, native to my country, with a long history of cultivation, which was recorded in the Tang Dynasty more than a thousand years ago. Introduced by the Italian Marco Polo in the Yuan Dynasty, tung oil gradually spread overseas. [0003] Tung oil is widely used in the coating of wood products or paper products to prevent moisture, mildew, s...

AI Technical Summary

Problems solved by technology

[0003] Tung oil is widely used in the coating of wood products or paper products to prevent moisture, mildew, sun protection, anti-bacteria, etc., but when traditional tung oil products are coated, the drying speed is slow and multiple coatings are required. However, it takes up a lot of space, time-consuming and labor-intensive, and the cost is very high, which limits the further application of tung oil

The weather-resistant wood oil whose main component is tung oil is also mainly used for moisture-proof, moldy, sun-proof, anti-bacterial, etc. of wood products or paper products. For example, it is widely used in wooden floors in homes or public places, but it also has the above-mentioned shortcomings. The time even takes 2 to 6 days, and the existing weather-resistant wood oil is difficult to penetrate deeper into the wood product, resulting in a shorter service life of the wood product only on the surface of the wood product. For outdoor use, how to prevent ultraviolet rays and anti-stripping are also defective

In addition, no matter tung oil or weathering wood oil has pungent smell, it has pollution to the environment
