Problems solved by technology

Although the foam packaging materials of petrochemical origin used in industrial products are light in weight, good in compressive and shock resistance, and easy to use, due to the characteristics of foam plastic products, such products have problems such as not easy to degrade and pollute the environment. will inevitably have an adverse impact on the environment
Now many places overuse non-degradable plastic products, white pollution has appeared
In order to solve this problem, the use of pulp to produce easily degradable and recyclable pulp molded products came into being. However, there are still many problems in pulp molded products, such as the production cost is generally higher than that of foamed foam products from petrochemical sources, production The process is accompanied by a large amount of wastewater discharge, which has a certain impact on the environment and has poor anti-buffering ability

Embodiment 1

[0022] Example 1: Using mushrooms to cultivate degradable packaging materials

[0023] Take 68g of crushed wheat straw, 20g of cottonseed husks, 5g of rice bran, 5g of wheat bran, 1g of sucrose, and 1g of calcium sulfate, add 60g of water and mix thoroughly, put them into a prefabricated high-temperature-resistant plastic or glass model, and heat them at 121°C. Sterilize under conditions for 25 minutes (min), cool to room temperature, insert the pre-cultivated mushroom strains on the ultra-clean workbench, and place them in an incubator with an ambient temperature of 20°C for cultivation. Cultivate for 15 days until the mushrooms are ready. Take it out after it is full, and dry it in an oven at 80°C for more than 24 hours (h) to inactivate the hyphae, and the sample completes the production process.

Embodiment 2

[0024] Example 2: Using Chizhi to Cultivate Degradable Packaging Materials

[0025] Take 96g of crushed wheat straw, 40g of cottonseed husk, 40g of corncob, 10g of rice bran, 10g of wheat bran, 2g of sucrose, 2g of calcium sulfate, add 120g of water and mix well, put it into a prefabricated high-temperature-resistant plastic model, and heat it at 115°C Sterilize for 25 minutes under the condition of the ultra-clean workbench, insert the red sesame strains that have been cultivated with the potato medium in advance, and place them in an incubator with an ambient temperature of 30°C for cultivation. Take it out after it is full, and dry it in an oven at 50°C for more than 24 hours to inactivate the mycelium, and the sample completes the production process.

Embodiment 3

[0026] Example 3: Using Ganoderma lucidum to cultivate degradable packaging materials

[0027] Take 136g of crushed cottonseed hulls, 40g of wheat straw, 10g of rice bran, 10g of wheat bran, 2g of gypsum powder, and 2g of sucrose, add 120g of water and mix well, put them into a prefabricated high-temperature-resistant plastic model, and extinguish them at 115°C. For more than 30 minutes, insert the pre-cultured Ganoderma lucidum strains on the ultra-clean workbench, place them in an incubator with an ambient temperature of 25°C, and cultivate them for 15 days. After the hyphae are full, take them out. Dry in an oven at 60°C for more than 24 hours to inactivate mycelia, and the sample completes the production process.

Abstract

The invention relates to a degradable material and a preparation method. Biomass resources are used as raw materials, are mixed with auxiliary materials and are placed into a mold to be sterilized, then, microbes are inoculated for culture, and the degradable material can be obtained through drying. The production raw materials of the degradable material have rich sources and low price, no three waste is generated in the production process, and the environment is not polluted. Products produced by using the technical scheme of the invention have the advantages that the weight is light, the pressure-resistance intensity and shock-resistance intensity are good, the damp-proof and mildew-proof effects are realized, in addition, the degradation is easy, the degradable material can be recovered to be used as organic fertilizers after being degraded, and the degradable material is suitable for industrial production.

Description

technical field [0001] The invention relates to a degradable material. [0002] The present invention also relates to a preparation method of the above-mentioned degradable material. [0003] The present invention also relates to the application of the above-mentioned degradable materials. technical background [0004] With the continuous development of modern industry and the continuous popularization of daily household appliances, the demand for product packaging materials continues to grow, and the market prospect is broad. At present, there are mainly two types of packaging materials used in the market: one is the foam material derived from petroleum , this type is represented by polystyrene and polyurethane; the second is a substitute for foamed materials - pulp molded products. Although the foam packaging materials of petrochemical origin used in industrial products are light in weight, good in compressive and shock resistance, and easy to use, due to the characteris...
