Problems solved by technology

Although the flower pots produced by the above methods can also meet the advantages of degradability, good environmental adaptability and low cost, the water resistance of the flower pots produced by the prior art is not enough and requires special crushing equipment to cause large dust pollution. And the raw materials used cannot give the plant more growth-promoting raw materials in terms of nutrients

Embodiment 1

[0033] Example 1 Preparation of disposable degradable lightweight flower pots

[0034] 1) Weigh a certain amount of PVA and add it to the beaker, add distilled water with a mass of 8 to 9 times that of PVA in total (distilled water is added several times during the swelling process), put the beaker in a water bath, heat it to 40°C and stir it at a low speed with the rotor for 40°C Swell for more than 10 minutes (if the PVA is directly dissolved at high temperature, there will be bag-like and skin-dissolved endogenous phenomena, which cannot be dissolved normally) until the volume of PVA increases to about 7 times of the beginning, and the color becomes blue-gray. Raise the temperature of the water bath to 98°C, increase the stirring rate and stir for 1 hour, and then completely dissolve the PVA in the water;

[0035] 2) Take another beaker, add a certain amount of starch and insect droppings into it, add some water and stir evenly, then mix the starch and insect dropping suspe...

Embodiment 2

[0053] Example 2 Determination of Group Distribution Ratio

[0054] Experiments were carried out according to the proportion of components shown in Table 2 to obtain several groups of samples, and their hardness, brittleness, appearance and cost were evaluated.

[0055] Table 2 Distribution ratio test data

[0056]

[0057] Among these groups of samples, sample 3 has the best performance and appearance, and sample 6 is not bad.

Embodiment 3

[0058] Embodiment 3 Determination of the amount of crosslinking agent epichlorohydrin

[0059] Epichlorohydrin can cross-link modified starch and PVA under alkaline conditions. In order to determine the amount of cross-linking agent, it is possible to control the ratio of PVA starch insect feces and change the amount of cross-linking agent within a suitable range. According to the experimental steps of the above-mentioned chemical cross-linking method, the sample is manufactured, and after it is dried, compare the apparent properties of the sample to roughly determine the amount of cross-linking agent. The detection data are shown in Table 3:

[0060] Table 3 Selection of crosslinking agent dosage

[0061]

[0062] It can be seen from Table 3 that the water absorption rate of the third group of samples is the lowest, the hardness is good, and the toughness is not much different from that of other groups, so the dosage of the third group of crosslinking agent is the most ap...

Abstract

The invention discloses a disposable and degradable light self-nutrition-supply flowerpot and a preparing method thereof. The flowerpot is prepared by making tenebrio molitor fecula, starch and PVA reacted under the action of a crosslinking agent to form a mixture with elasticity, and then pressing the mixture. The invention further discloses the preparing method of the flowerpot. The obtained flowerpot is smooth and clean in surface, soft in color and luster, fine in texture, high in stiffness and toughness, light, not prone to breakage, convenient to deliver, transport and use in daily life, large in temperature difference adaptation range, good in breathability and degradable, and matter generated after degradation can serve as nutrition of plants. The flowerpot has the greatest advantages of being low in price and high in quality, and is an environment-friendly product according with cyclic economy.

Description

technical field [0001] The invention belongs to the technical field of flowerpots, and in particular relates to a disposable degradable self-nutrition light flowerpot and a preparation method thereof. Background technique [0002] With the rapid development of social economy, people's life has become more and more colorful. Decorating life with flowers has changed from fashion to essential. In Europe, flowers have become an important part of the planting industry. British seedling pots The demand for flower pots and potted plants has increased sharply, indicating that flower art has become an indispensable part of daily life. However, while people enjoy the wonderful landscape, they also bring certain pollution to the environment. [0003] Ordinary plastic flower pots will bring white pollution to the environment. The polyethylene plastic flowerpots that are restricted in production in Europe have caused serious white pollution to the earth. The power of this kind of white...
