Problems solved by technology

In the existing gray oil, only a single raw tung oil is used, so the prepared gray oil has a relatively strong oily fragrance of tung oil, which is unacceptable to most users
Moreover, the existing gray oil is relatively viscous, and it is not easy to spread during the smearing process, and it cannot meet the technical requirements of high viscosity and easy smearing and spreading at the same time
[0003] In addition, at present, in the preparation process of gray oil, simple heating reaction vessels are used, so that the contact area between raw tung oil and oxygen is limited during the heating and aging process, resulting in a low degree of aging and affecting its viscosity.
At the same time, in the process of heating liquid oil, it is easy to cause local overheating, resulting in uneven aging, and ultimately lead to poor performance of gray oil

Abstract

The invention provides an ash oil for antique building materials and a preparation method thereof. The ash oil is prepared from the following raw materials in parts by weight: raw tung oil, Moringa oleifera seed oil, flaxseed oil, catalpa oil, minium powder, soil seed powder, litharge and graphene powder. The preparation method comprises the following steps: adding the raw tung oil into a reaction kettle, heating, and keeping the temperature, wherein the raw tung oil is kept in an oxygen-rich atmosphere in the process; adding the other vegetable oils into the raw tung oil, uniformly mixing, heating, adding the minium powder, soil seed powder and graphene, uniformly mixing, continuing heating, keeping the temperature, and naturally cooling. The invention also provides a reactor for the preparation process. The reactor ensures sufficient cooking and heating uniformity of the raw tung oil, and further implements accurate control on the parameters. The ash oil can be matched with brick dust and green blood to obtain the ash oil putty; and the ash oil putty is suitable for repairing and filling the antique building materials, is especially suitable for antique building wood, performs excellent functions of filling wood, and can resist water, corrosion, moths, bacteria and ultraviolet light.

Description

technical field [0001] The invention relates to the technical field of ancient building materials, in particular to gray oil used for ancient building materials and a preparation method thereof. Background technique [0002] At present, gray oil is a waterproof and moisture-proof additive for painting walls during decoration, and it is mostly used for decoration construction. Traditional ash oil is made by adding a small amount of soil seed powder and Zhangdan powder to raw tung oil according to a certain proportion, and refining it. Raw tung oil is golden in color, relatively thin, and not as thick as cooked tung oil. Therefore, cooked tung oil is more suitable for anti-corrosion and moisture-proof materials. In the existing gray oil, only a single raw tung oil is used, so the peculiar oil fragrance of tung oil in the prepared gray oil is relatively large, and this oil fragrance is unacceptable to most users. Moreover, the existing gray oil is relatively viscous, and in t...
