[0022] A preparation method of urushiol environment-friendly ancient building paint, comprising the steps of:

[0023] Filtrating the raw lacquer to obtain the filtered raw lacquer;

[0024] Dehydration is carried out to filtering raw lacquer, obtains dehydration raw lacquer; Preferably, described dehydration adopts electric tungsten filament lamp to heat (avoid heating tube heating local temperature too high), heating time is one week, after dehydration, the mass fraction of the moisture in the dehydration raw lacquer is 3-5%; or the mass fraction of moisture in the dehydrated raw lacquer is less than 3%.

[0025] Stirring and defoaming: the motor is used to stir in three stages to increase the temperature and increase the compatibility (traditionally, manual stirring is used). The first stage, low-speed stirring: the stirring speed is 40-150r / min, and the stirring time is 20-36h; the second stage, High-speed stirring to heat up and solubilize: stirring speed 800-1500r / min, ...

Abstract

The invention discloses a preparation method of urushiol environment-friendly ancient building paint, which comprises the following steps: filtering raw lacquer to obtain filtered raw lacquer; dehydrating the filtered raw lacquer to obtain dehydrated raw lacquer; stirring deforming, wherein a motor is adopted for stirring in three stages to improve the temperature and increase the compatibility, in the first stage, low-speed stirring is conducted, specifically, the stirring speed is 40-150 r / min, and the stirring time is 20-36 h; in the second stage, high-speed stirring is conducted to increase the temperature and solubilize, specifically, the stirring speed is 800-1500 r / min, and the stirring time is 0.5-1.5 h; then a weather-resistant and heat-resistant auxiliary agent is added; in the third stage, defoaming and stirring are conducted, specifically, the stirring speed is 20-1500 r / min, the stirring time is 1.5-3 h, and solubilized raw lacquer is obtained; sealing and naturally precipitating the solubilized raw lacquer to obtain layered raw lacquer; and uniformly mixing the layered raw lacquer, grinding and filtering to obtain the urushiol environment-friendly ancient building paint. The special performance of natural raw lacquer is maintained, the defects are eliminated, meanwhile, the weather resistance, the heat resistance and the ultraviolet resistance are improved, and the anaphylactic reaction on people is reduced.

Description

technical field [0001] The invention belongs to the technical field of raw lacquer, and in particular relates to a preparation method of urushiol environment-friendly ancient building lacquer. Background technique [0002] Chinese raw lacquer, commonly known as "natural raw lacquer", also known as "national lacquer" or "earth lacquer", "raw lacquer" and "big lacquer", as a special forestry product in China, is one of the important materials traditionally exported by China. The quantity is good and the quality is famous in the world. Known as the "king of paint" in the world. [0003] Raw lacquer is a renewable environment-friendly natural polymer coating, and it is also a special native product of traditional forestry in my country. Its main components include urushiol (60-65%), water (20-30%), gum (5-7%), glycoprotein (1-2%) and laccase (<1%), etc. Known as the "King of Paint". The raw lacquer currently on the market has slow curing rate, poor heat resistance, poor w...
