preparation example Construction

[0026] The preparation method of the high-efficiency plant anti-mildew coating composition of the present invention is to dry and pulverize hibiscus bark and tree peony bark, soak them in an aqueous ethanol solution with a concentration of 75-90% for 15-24 hours, and use them under the condition of 60-80°C Extract by conventional heating and reflux method to obtain the extracts of hibiscus cortex and peony cortex; mix the two extracts in proportion and concentrate under reduced pressure at 50-70°C to obtain a concentrated solution with a Baume specific gravity of 1.15-1.20, or The two extracts are respectively concentrated under reduced pressure and mixed in proportion, and their effects are equivalent; add quaternary ammonium salt, 75% ethanol aqueous solution and distilled water to the mixed concentrated solution and stir to homogenize.

[0027] The composition product prepared according to the above method not only has the high-efficiency and rapid antibacterial advantages o...

Embodiment 1

[0032] A, the preparation of hibiscus bark extract: the hibiscus bark is dried to moisture content and pulverizes after being less than 1%, gets less than 100 mesh powders, filters after 24 hours with the 90% concentration ethanol aqueous solution of 4 times of powder weights, Then heat the filtrate to 60-80°C, extract twice by conventional heating and reflux method, and extract for 2 hours each time, and filter the extract for later use;

[0033] B. Preparation of Moutan Cortex Extract: Dry the Moutan Cortex to a moisture content of less than 1% and then pulverize it. Take 200 mesh powder and soak for 24 hours in 75% ethanol solution with 3 times the weight of the powder. Under the condition of ℃, heat and reflux extraction twice, each extraction is 2 hours, and the extract is filtered for later use;

[0034] C. The hibiscus cortex and Moutan cortex extracts obtained in the two processes of A and B are respectively concentrated under reduced pressure at 50-70°C to form a conc...

Embodiment 2

[0042]A, the preparation of hibiscus bark and tree peony cortex extract: dry hibiscus bark and tree peony bark respectively and pulverize, get the powder material under 200 mesh sieves, soak 24 hours respectively with 75% ethanol aqueous solution 3 times of above-mentioned powder material, Then use the conventional heating and reflux process to extract twice, each extraction time is 1 hour, and the extract is filtered for later use.

[0043] B. Mix the hibiscus bark and tree peony bark filtrate obtained in sequence A in proportion after content detection, and concentrate under reduced pressure at 60-80°C to form a concentrated solution (extract) with a Baume specific gravity concentration of 1.15-1.20 for future use .

[0044] C. Take the commercially available 1227 quaternary ammonium salt and add it to the sequence B concentrated solution (extract) in proportion, then add 75% ethanol aqueous solution, and stir and mix evenly.

[0045] The proportions of each component are a...

Abstract

An efficient plant mildew-proof coating composition includes active components to be natural plant extracts extracting from pseudolarix and moutan bark, and auxiliary components to be quaternary ammonium salt, ethanol and distilled water, etc. With the extracts extracting from pseudolarix and moutan bark which have good mildew-proof function in traditional Chinese medicines, the efficient plant mildew-proof coating composition solves the defects of large consumption, high side effects, difficult degradation in prior chemical mildew-proof agents, and has the environment-friendly and the safe characteristics of natural plant mildew-proof agents. The raw materials thereof have widely sources and the production cost is low. By adopting the cationic surfactant quaternary ammonium salt, the inventive mildew-proof coating composition has the rapid and efficient mildew-proof advantage of chemical medicine and overcomes the disadvantages of low efficiency and slow speed in prior plant mildew-proof agents. The inventive composition coating is applicable to preventing and controlling the mildew generation on object (article) surfaces, and the widely range of application includes mildew control and corrosion control of water pipes, equipment, ancient architectures, metals, cements, wood, ceramic tiles, marbles, paper, fabric, toilet walls and grounds, and food processing workshops.

Description

technical field [0001] The invention relates to an antimold preparation and a preparation method thereof, in particular to an antimold preparation with plant extracts as an active component and a preparation method thereof. Background technique [0002] Mold is ubiquitous in the natural environment and human life, and it is extremely harmful to industry, agriculture, ancient buildings, food safety and people's life and health. [0003] At present, there are more than 200 different types of chemical antifungal agents on the market. For example, DC-5700 organic silicon quaternary ammonium salt of Dow Corning Corporation of the United States, nano-silver and photocatalyst anti-mildew coating of Shenzhen New Nano Application Technology Co., Ltd., etc. These chemical antifungal agents generally have a one-time effect, and have the disadvantages of large consumption and difficult degradation, and are likely to bring persistent pollution and damage to the ecological environment. ...
