Problems solved by technology

Shock-absorbing and cushioning packaging materials can be made by using crushed crop straw and adhesives as raw materials, after mixing, cross-linking reaction, foaming, casting, baking and setting, and natural drying. It is cheap, easy to get, and degradable, but the binder needs to use rubber or other chemically synthesized refractory substances, which cannot guarantee complete environmental protection
The latter two are only suitable for making small particle foam cushioning materials due to their poor recovery and poor strength.

Embodiment 1

[0059] Example 1: Mix the coarsely crushed wheat crop stalks and the finely crushed wood scraps at a weight ratio of 90:10 to form a solid mixed powder; the solid mixed powder is mixed with water in proportion and then sterilized as a culture medium. The weight ratio of mixed powder to water is 80:20, heat the mixed medium to 200°C for sterilization; in the sterile space, the temperature is 15°C, the relative air humidity is 95%, the medium is put into the mold, Inoculate the culture medium with liquid strains and cultivate for 10 days; after the mycelium is overgrown and the fruiting body grows to form the surface layer of the fruiting body, dry the medium at 40°C to keep the water content at 5%. In between, the dried culture medium is peeled off from the mold, which is the buffer material.

Embodiment 2

[0060] Embodiment 2: the mixture of coarsely crushed indica rice crop stalks, rye crop stalks, corn crop stalks, soybean crop stalks, sweet potato crop stalks and finely crushed wheat bran and rice The mixture of shell powder is mixed into solid mixed powder at a weight ratio of 10:90; the solid mixed powder is mixed with water in proportion and then sterilized as a culture medium, and the weight ratio of solid mixed powder to water is 50:50. The good medium is heated to 80°C for sterilization; in the sterile space, the temperature is 25°C, and the relative humidity of the air is 70%. Put the medium into the mold, inoculate the medium with liquid bacteria, and cultivate it for 6 days; After the silk grows and grows fruiting bodies to form the surface layer of fruiting bodies, dry the culture medium at a temperature of 100°C to retain 10% of the water in it. After drying, the culture medium is peeled off from the mold, which is the buffer material .

Embodiment 3

[0061] Embodiment 3: the rapeseed stalk crop stalk crushed powder of coarse crushed powder, the shavings crushed powder mixture and the wheat bran powder of finely crushed powder are mixed into solid mixed powder in a weight ratio of 60:40; solid mixed powder and water are mixed in proportion Mix and sterilize as a medium, the weight ratio of solid mixed powder to water is 70:30, heat the mixed medium to 120°C for sterilization; in the sterile space, the temperature is 35°C, and the relative air humidity is 75%. Put the culture medium into the mold, inoculate the culture medium with liquid strains, and cultivate for 3 days; after the mycelium is full and the fruiting body grows to form the surface layer of the fruiting body, the medium is dried at a temperature of 150°C. Keep the water content at 20%, and peel off the dried medium from the mold, which is the buffer material.

Abstract

The invention discloses a method for preparing a buffer material from plant straws. The method is used for buffer material manufacture. The method comprises dehydrating, crushing and mixing plant straws and wood wastes, mixing the powder and water according to a certain ratio to obtain a uniform mixture, sterilizing the mixture as a medium, putting the medium into a mold in an aseptic environment, inoculating the medium with a liquid strain, carrying out culture under control of ambient conditions, after the mycelia fills the medium, develops sporocarp and forms a sporocarp surface layer, carrying out drying and then separating the medium and the mold to obtain the buffer package material. The agricultural production plant straws and forestry production wood waste are recovered and are used for preparing the buffer package material. The method has simple processes, does not produce pollution, has a low production cost and is an economic, effective and environmentally friendly buffer material production technology. The product has good buffer performances and can be degraded easily.

Description

technical field [0001] The invention relates to the technical field of buffer materials, in particular to a method for manufacturing buffer materials from plant straws. Background technique [0002] Foam plastic has become a widely used cushioning material in modern times due to its good cushioning performance and shock absorption performance. Foam plastics have the advantages of light weight, easy processing, good protection performance, wide adaptability, low price and high quality, but there are also disadvantages such as large size, waste cannot be weathered naturally, and harmful gases will be generated when incinerated. In the case of serious environmental pollution and scarcity of natural resources, the harm of foamed plastics to the environment has attracted great attention. Although degradable plastics have been developed with the development of science and technology, such plastics are expensive, require strict processing conditions, and cannot be completely degra...
