[0015] (A) Preparation of biological enzyme: Weigh 15 g of soybean peptone and dissolve it in 100 ml of deionized water, place the solution in a water bath, raise the temperature to 75-85°C, and add an appropriate amount of hydrochloric acid or citric acid to make the solution The pH is 4~5, stir and hydrolyze, the hydrolysis time is 5 hours, after the reaction is completed, the solution is cooled to obtain the biological enzyme, and put it into a brown bottle for later use.

[0016] (B) Preparation of plant extracts: Dried pomegranate peel, ivy, Angelica dahurica, cinnamon, and honeysuckle, put them into a grinder, and ground them for 4 hours. After grinding, each material was passed through a 50-100 mesh sieve to obtain each material powder. Take 10 g of each of the above powders and disperse them into five beakers filled with 100 ml of deionized water, soak them overnight, ultrasonicate for 2 hours, then put them into a distillation equipment for distillation for 1 hour, co...

Embodiment 1

[0018] Disperse 15 ml of the biological enzyme prepared in step (A) into 50 ml of deionized water, stir well, and add the plant extract prepared in step (B) while stirring, 8 ml of pomegranate peel extract, 8 ml of ivy extract ml, 8 ml of Angelica dahurica extract, 3 ml of cinnamon extract, 2 ml of honeysuckle extract, stir for 1 hour, then add 1 ml of sodium carboxymethyl cellulose solution, 18 ml of alcohol, stir well, and finally obtain a highly efficient formaldehyde-degrading composite material, At the same time, the composite material has a good killing effect on bacteria such as Escherichia coli, Staphylococcus aureus, and Candida albicans.

Embodiment 2

[0020] Disperse 10 ml of the biological enzyme prepared in step (A) into 50 ml of deionized water, stir well, and add the plant extract prepared in step (B) while stirring, 5 ml of pomegranate peel extract, 5 ml of ivy extract ml, 5 ml of Angelica dahurica extract, 5 ml of cinnamon extract, 3 ml of honeysuckle extract, stir for 1 hour, then add 1 ml of xanthan gum solution, 20 ml of alcohol, stir well, the effect of degrading formaldehyde is not as good as that of Example 1, but the bactericidal effect Visibly enhanced.

Abstract

The invention relates to a preparation method of a formaldehyde degradation composite material formed by compounding bioenzyme and plant extracting liquid. The preparation method comprises the following steps: firstly, preparing bioenzyme by utilizing an acid method, dispersing the prepared bioenzyme into deionized water, adding five plant extracting liquid while stirring, then adding a stabilizer and alcohol, and fully stirring to finally obtain the degradation formaldehyde composite material. The composite material contains the following raw materials in percentage by mass: 10%-18% of bioenzyme solution, 5%-10% of pomegranate bark extracting liquid, 5%-10% of Chinese ivy stem extracting liquid, 5%-10% of radix angelicae extracting liquid, 2%-5% of cortex cinnamomi extracting liquid, 1%-3% of honeysuckle extracting liquid, 1%-2% of a stabilizer, 4%-20% of alcohol, and 22%-66% of deionized water. After being sprayed to the surface of a formaldehyde-containing base material, the composite material has the advantages of being strong in formaldehyde degradation capacity, stable and durable in effect and the like, as well as having strong sterilization capability.

Description

technical field [0001] The invention belongs to the technical field of functional materials, and in particular relates to a preparation method of a formaldehyde degradation composite material. Background technique [0002] In our daily life, formaldehyde is ubiquitous. For example, the MDF, plywood, particle board and other boards used in the decoration of new houses emit formaldehyde; some home decorations also emit formaldehyde, and the amount of formaldehyde released can be as long as 3- For 15 years, being in an environment where formaldehyde exceeds the standard for a long time can cause various diseases, have a great impact on human health, and even endanger human life. Although a variety of formaldehyde scavenger products have appeared on the market, there are some defects in these formaldehyde scavenger products, such as: photocatalyst formaldehyde scavenger needs the auxiliary effect of ultraviolet light to decompose formaldehyde; Good, but it will cause secondary ...
