Embodiment 1

[0038] The varnish used for ancient building materials is made from the following raw materials in parts by weight: 55 parts of raw tung oil, 10 parts of moringa seed oil, 10 parts of linseed oil, 5 parts of catalpa oil and 30 parts of rosin.

[0039] The preparation method of the varnish of present embodiment 1 may further comprise the steps:

[0040] Step 1, prepare each raw material according to the varnish described in claim 1 or 2;

[0041] Step 2: Add raw tung oil into the reaction tank, heat to 180°C, keep warm, and keep the raw tung oil in an oxygen-enriched atmosphere during the heating and heat preservation process; then add the hot tung oil to Moringa seed oil, linseed oil and catalpa oil , mix well and heat up to 200°C, keep warm to get mixed vegetable oil;

[0042] Step 3. Add rosin to the mixed vegetable oil obtained in step 2. After the rosin is melted and mixed evenly, continue to heat up to 265°C and keep it warm for 2 hours. During the heat preservation proc...

Embodiment 2

[0044] The varnish used for ancient building materials is made from the following raw materials in parts by weight: 52 parts of raw tung oil, 5 parts of moringa seed oil, 5 parts of linseed oil, 3 parts of catalpa oil and 25 parts of rosin.

[0045] The preparation method of the varnish of this embodiment 2 is the same as the preparation method of embodiment 1.

Embodiment 3

[0047] The varnish used for ancient building materials is made from the following raw materials in parts by weight: 60 parts of raw tung oil, 15 parts of moringa seed oil, 15 parts of linseed oil, 8 parts of catalpa oil and 35 parts of rosin.

[0048] The preparation method of the varnish of the present embodiment 3 is the same as the preparation method of embodiment 1.

Abstract

The invention provides gloss oil for historic building materials and a preparation method thereof. The gloss oil is prepared from the following raw materials: raw tung oil, moringa oleifear seed oil, flax seed oil, stillingia oil, rosin, lithargite and aerogel powder. The preparation method of the gloss oil comprises the following steps: adding raw tung oil into a reaction tank, heating and carrying out thermal insulation, wherein it is ensured that raw tung oil is in an oxygen-enriched atmosphere during the process; adding other vegetable oil into raw tung oil, uniformly mixing, heating, adding rosin and aerogel powder, uniformly mixing, continuously heating, carrying out thermal insulation, adding lithargite, dissolving, and naturally cooling. In allusion to the above preparation method, the invention also provides a reaction device to guarantee full curing of raw tung oil and heating uniformity and further realize accurate control of parameters. The gloss oil of the invention is used for surface protection of historic building materials, especially protection of wood surface, has waterproof, corrosion resistant, ultraviolet-proof and sterilization effects, and can enhance surface glossiness, hardness and hand feeling.

Description

technical field [0001] The invention relates to the technical field of ancient building materials, in particular to a varnish used for ancient building materials and a preparation method thereof. Background technique [0002] Varnish, also known as cooked tung oil, bright oil, also known as clear oil in some places, is made by heating raw tung oil. The tung oil of this type of varnish has a strong oil fragrance, and the oil fragrance will still permeate the environment for a long time after the construction is finished, causing environmental pollution. Moreover, the varnish has a single component, only plays the role of waterproof and anticorrosion, and has a single function. [0003] In addition, at present, in the preparation process of varnish, 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,...
