Embodiment 1

[0030] 1. Dry the coarse grass powder of Eupatorium adenophorum so that the water content is less than 10%, crush it through an 80-mesh sieve, and obtain refined grass powder;

[0031] 2. Prepare dexvalerthrin as 1mg / ml acetone solution; measure 2.0ml of the above solution with a pipette gun, dexvalerethrin is 0.002g (0.067 parts), and add it evenly to 2.998g (100 part) on the fine grass powder, stir evenly, let stand to make the acetone fully volatilize;

[0032] 3. After the acetone is completely volatilized, transfer the mixed mixture to a mold, and press it into a tablet under a pressure of 20 MPa.

Embodiment 2

[0034] 1. Dry the coarse grass powder of Eupatorium adenophorum so that the water content is less than 10%, and crush it through a 100-mesh sieve to obtain refined grass powder;

[0035] 2. Pass the activated carbon powder through a 120-mesh sieve and set aside;

[0036] 3. Prepare dexvalerthrin as 20mg / ml acetone solution; measure 2.0ml of the above solution with a pipette gun, dexvalerethrin is 0.040g (1.423 parts), evenly add to 2.810g (100 part) on the fine grass powder, stir evenly, let stand to make the acetone fully volatilize;

[0037] 4. After the acetone is completely volatilized, mix the above mixture with 0.150g (5.338 parts) of activated carbon powder;

[0038] 5. Transfer the mixed mixture to a mould, and press to form a tablet under a pressure of 15 MPa.

Embodiment 3

[0040] 1. Dry the coarse grass powder of Eupatorium adenophorum so that the water content is less than 10%, and crush it through a 120-mesh sieve to obtain refined grass powder;

[0041] 2. The silicon dioxide powder is passed through a 120-mesh sieve for use;

[0042] 3. Prepare d-valerythrin as 40 mg / ml acetone solution; measure 1.0 ml of the above solution with a pipette gun, 0.040 g (1.423 parts) of d-valeraterin, add to 0.150 g (5.338 parts) evenly part) on silicon dioxide, stir evenly, and let stand to make the acetone fully volatilize;

[0043] 4. After the acetone is completely volatilized, mix the above mixture with 2.810g (100 parts) of fine grass powder;

[0044] 5. Transfer the blended mixture to a mould, and press to form a tablet under a pressure of 10 MPa.

Abstract

The invention relates to a mothproof and mildewproof agent taking Eupatorium adenophorum as a carrier and a preparation method thereof, in particular to ahealth, high-efficiency and multifunctional mothproof and mildewproof agent for leather, wool, silk floss products, books and the like. The mothproof and mildewproof agent is compounded by taking camphor, esbiothrin, lavender and the like safe to the human body as effective components, taking Eupatorium adenophorum as the carrier, and adding a certain amount of additive. The mothproof and mildewproof agent has long-acting, safe and slow-release mothproof and mildewproof effects, more importantly, the Eupatorium adenophorum is changed from harm into valuable, a new way for recycling the Eupatorium adenophorum is opened up, and the environmental pressure is relieved to a certain degree.

Description

Technical field: [0001] The invention relates to an anti-moth and anti-fungal agent using Eupatorium adenophorum as a carrier and a preparation method thereof. In particular, it is a healthy, efficient and multifunctional anti-moth and anti-mold agent for leather, wool, silk floss products, books and other articles. Background technique: [0002] With the improvement of living standards, people have higher and higher requirements for anti-mildew and anti-moth products, and the demand is also increasing. Anti-mildew and anti-moth products on the domestic market are mainly made of camphor, naphthalene, p-dichlorobenzene, etc. as active ingredients. Naphthalene, as the earliest anti-moth agent, was stopped in many countries and regions in the world in the 1980s due to its toxicity and carcinogenic effects. my country also issued relevant documents in the 1990s to prohibit the production and sale of naphthalene However, due to its good anti-mite effect and low price, there are ...
