preparation example Construction

[0026] The embodiment of the present invention discloses a method for preparing a permeate, comprising the following steps: mixing an acidic palladium salt solution, a solvent and polyvinylpyrrolidone (PVP), and stirring to obtain a first mixed solution; adding the orthosilicate solution dropwise In the first mixed solution, the mixture is statically aged after stirring to obtain a second mixed solution; phosphomolybdic acid and a preservative are added dropwise to the second mixed solution, and a permeate solution is obtained after stirring.

[0027] According to the present invention, the solvent is preferably a hydrophilic solvent with 2-8 carbon atoms; the orthosilicate is ethyl orthosilicate, methyl orthosilicate or propyl orthosilicate. The preferred dosage of raw materials in the permeate is as follows:

[0028]

[0029] More preferably, in the described permeate, the raw material consumption is as follows:

[0031] More preferably, in the described perm...

Embodiment 1

[0061] The fresh cut flowers selected in this example are white gardenias. The preservative, ethyl p-hydroxybenzoate, was purchased from Zhengzhou Lvbo Chemical Products Co., Ltd.

[0062] A preserved flower with carbon monoxide warning function, the preparation method thereof is as follows:

[0063] 1) Fresh cut flowers are washed and arranged, placed in ethanol for dehydration for 24 hours to remove tissue fluid in cut flower cells, and a small amount of molecular sieve is added to the dehydrating agent to improve water removal efficiency;

[0064] 2) immerse the fresh cut flowers after dehydration in permeate at room temperature for 24 hours;

[0065] 3) Arrange the infiltrated fresh cut flowers, remove the surface liquid, and place them in a 50°C oven to dry slowly.

[0066] The preparation method of above-mentioned permeate is as follows:

[0067] 1) Dissolving 0.2g palladium chloride with 0.5ml mass concentration of 15% hydrochloric acid, adding 17.5ml ethanol, 8.7g p...

Embodiment 2

[0073] The fresh cut flowers selected in this embodiment are pink camellias. Potassium sorbate, a preservative, was purchased from Ningbo Wanglong Group Co., Ltd., and polyethylene glycol (PEG) was purchased from Sinopharm Reagent.

[0074] A preserved flower with carbon monoxide warning function, the preparation method thereof is as follows:

[0075] 1) fresh cut flowers are washed and arranged, placed in n-butanol for dehydration for 24 hours to remove tissue fluid in the cut flower cells, and anhydrous calcium chloride is added in the dehydrating agent to improve water removal efficiency;

[0076] 2) immerse the fresh cut flowers after dehydration in permeate at room temperature for 24 hours;

[0077] 3) Arrange the infiltrated fresh cut flowers, remove the surface liquid, and place them in a 55°C oven to dry slowly.

[0078] The preparation method of above-mentioned permeate is as follows:

[0079] 1) dissolve 0.5g palladium chloride with 0.8ml mass concentration of 20%...

Abstract

The invention provides a preparation method of a preserved flower for early CO warning. The method comprises the following steps: firstly, with palladium chloride as a raw material, reacting a divalent palladium ion with carbon monoxide to generate elemental palladium, oxidizing elemental palladium with phosphomolybdic acid, and restoring into molybdenum blue, so that early warning of CO is realized by the preserved flower through the change of color and luster; secondly, hydrolyzing a regular silicate ester under the catalysis of acid to obtain silica sol, wherein the silica sol has a porous structure after being dried, and can load phosphomolybdic acid molecules, and the specific surface area of the phosphomolybdic acid is improved, so as to improve the reaction efficiency; thirdly, improving the dispersity of various reaction matters by polyvinylpyrrolidone, and preventing birdnesting of particles, so as to improve the sensitivity of carbon monoxide detection. Therefore, the preserved flower also has an early CO warning function when the environment is beautified. Correspondingly, the invention further provides a preparation method of penetrating fluid.

Description

technical field [0001] The invention relates to the technical field of preserved flowers, in particular to a preparation method of CO early-warning preserved flowers. Background technique [0002] Flowers are beautiful and fragrant, and have great ornamental value. They can beautify the environment and make people feel happy. They are widely loved by people. For a long time, people have dreamed that flowers will always be fresh and beautiful, always blooming undefeated. Preserved flowers are the use of organic preservation solution to replace the water of plants, which can keep the tissue and water of flowers completely, without watering, can maintain the same softness, freshness and beautiful posture of flowers for a long time, after dyeing treatment After that, the flowers can have nearly 100 kinds of gorgeous colors. [0003] At present, the preserved flower technology on the market mostly pursues the similarity with the real flower, and lacks other functions except dec...
