Problems solved by technology

The above-mentioned technical scheme and the existing processing method obtain the wide lacquer, and its internal water content occupies a certain proportion. When the water content is higher than a certain value, the wide lacquer is not easy to be coated on the surface of ancient buildings during use. At the same time, the adhesive force is small, and it has the defects of poor film-forming effect and easy falling off

Embodiment 1

[0020] Embodiment 1, a kind of preparation method of wide paint, comprises the steps:

[0021] Step S1, performing impurity-removing and filtering treatment on the raw lacquer;

[0022] Step S2, put the raw lacquer into the lacquer cooking container and boil to remove water to obtain purified raw lacquer; Step S3, put tung oil into a clean pot, then place it on a heater to heat, stir and test, stop heating and let stand after the test is passed Get cooked tung oil;

[0023] Step S4, mixing the purified raw lacquer obtained in the step S2 with the cooked tung oil obtained in the step S4 in proportion to obtain a pre-product, and then adding a surfactant to the pre-product to obtain a finished product.

Embodiment 2

[0024] Example 2, a preparation method of lacquer, differs from Example 1 in that the raw lacquer is subjected to anhydrous sodium sulfate water removal treatment prior to step S1; and after the impurity removal treatment by filtering in step S1, Put the raw lacquer into the lacquer boiling container and boil to remove the moisture for 30 minutes.

[0025] Step S1 and step S2 are specifically as follows:

[0026] Step S1, first adding anhydrous sodium sulfate to the raw lacquer for water removal treatment, and then performing impurity removal and filtration treatment for the raw lacquer;

[0027] Step S2, putting the raw lacquer into the lacquer boiling container and boiling to remove water for 35 minutes to obtain purified raw lacquer.

Embodiment 3

[0028] Embodiment 3, a kind of preparation method of wide lacquer, differs from embodiment 2 in that step S3, put tung oil into a clean pot, then place it on a heater to heat, stir and detect, and the detection operation is to use Test the cooked tung oil in a clean pot by thermometer measurement. When the temperature reaches 180°C, control the heating rate of the heater to 5°C / min, remove the heater after heating for 15 minutes, stop heating and let stand to obtain cooked tung oil.

Abstract

The invention discloses a preparation method of a Guang paint, wherein the preparation method comprises the following steps: step S1, removing impurities of raw paint and carrying out filtration treatment; step S2, putting the raw paint into a paint boiling container, and boiling to remove water to obtain purified raw paint; step S3, filling tung oil into a clean pot, then placing on a heater, heating, stirring and detecting, after qualified detection, stopping heating, and allowing to stand to obtain cooked tung oil; and step S4, mixing the purified raw paint obtained from the step S2 with the cooked tung oil obtained from the step S4 proportionally to obtain a prefabricated product, and then adding a surfactant to the prefabricated product to obtain a finished product. The surface of ancient buildings is coated with the prepared finished product, the film forming effect is good and the finished product is not easy to fall off.

Description

technical field [0001] The invention relates to the technical field of chemical improvement of coatings, in particular to a preparation method of wide coatings. Background technique [0002] Chinese raw lacquer is an excellent natural lacquer produced in my country. my country's raw lacquer production ranks first in the world. It has always been a traditional export product, and currently it is mainly exported to Japan and Southeast Asian countries. The paint film obtained from Chinese raw lacquer is black, and can also be made into brownish red. Due to the depth of color, its application range is greatly limited. Need to expand the scope of application. So far, although a lot of research work has been done on the structure and properties of raw lacquer at home and abroad, the light-color modification of raw lacquer has not achieved satisfactory results. Guangqi is a kind of natural lacquer, which is one of the special products of our country. [0003] Mixing raw lacque...
