(4) mixing the crude juice and the white spirit according to the volume ratio of 3: 2, uniformly mixing, placing the mixture into a reaction kettle, standing for 2-3h at the temperature of 105-110 ℃, centrifuging after standing, and taking the upper-layer juice to prepare the oriental arborvitae ancient branch juice;
the pretreatment solution is prepared from the following raw materials in parts by weight: 50-60 parts of potassium citrate, 8-10 parts of starch, 22-26 parts of sodium bicarbonate, 18-20 parts of calcium hydroxide, 16-20 parts of nicotinic acid, 25-30 parts of tert-butyl hydroquinone, 35-45 parts of fatty alcohol-polyoxyethylene ether sodium sulfate and 16-18 parts of magnesium silicate;
the preparation method of the pretreatment solution comprises the following steps:
(1) dissolving potassium citrate in water, stirring at the rotating speed of 150-;
(2) adding sodium bicarbonate and calcium hydroxide into the mixture prepared in the step (1), stirring for 40-50min at the rotating speed of 200-;
(3) adding the ball-milled mixture into ethanol, performing ultrasonic treatment at 35-45 ℃ for 20min, placing the mixture into an oven to be dried at 60-70 ℃ after ultrasonic treatment, adding the dried mixture into deionized water 40-50 times of the weight of the mixture, and uniformly stirring to obtain a pretreatment solution;
the preparation method of the insect-proof liquid comprises the following steps:
(1) uniformly mixing ethanol and deionized water, heating the mixed solution to 35-45 ℃, stirring at the rotating speed of 150r/min and 120-;
(2) adding sodium fluosilicate and dicumyl peroxide into the mixed solution treated in the step (1), stirring for 10-15min at the rotating speed of 50-60r/min, adding the rest raw materials into the mixed solution after stirring, and continuously stirring for 25-30min to prepare the insect-proof solution.
