Description

Technical Field

[0001] The invention relates to the technical field of packaging box preparation, and in particular to a nano-straw environmentally friendly packaging box and a preparation process thereof. Background Art

[0002] Straw is the general term for the stems and leaves (ears) of mature crops. Straw usually refers to the remaining part of wheat, rice, corn, potatoes, rapeseed, cotton, sugarcane and other crops (usually coarse grains) after harvesting seeds. More than half of the products of crop photosynthesis are present in the straw. Straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, and is a multi-purpose renewable biological resource.

[0003] Traditional cartons are usually made of kraft paper and corrugated paper. The raw material of paper is usually wood pulp, which is made by cutting down a large number of trees. In order to solve the ecological problem of traditional carton boards consuming a large amount of wood pulp, a nano-straw environmentally friendly packaging box and its preparation process are proposed. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the shortcomings of the prior art, the present invention provides a nano-straw environmentally friendly packaging box and a preparation process thereof. Various types of straws are mixed in proportion based on their characteristics, and then processed through a series of processes to prepare the packaging box by welding and gluing with nano-inorganic hybrid resin, which solves the problem of traditional old processes and old technologies and adopts all new processes and new technologies to manufacture new finished products.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a nano-straw environmentally friendly packaging box and a preparation process thereof, the specific steps are as follows:

[0008] Step 1: Select raw materials. The range of raw materials is relatively wide. The available materials are wheat straw, rice straw, soybean straw, corn straw and field crop straw of reed;

[0009] Step 2: Raw material screening. During the process of raw materials from the field to the production plant, there will be impurities such as iron and soil in the raw materials, which need to be screened;

[0010] Step 3: Initial cutting of raw materials, using dust-free intelligent cutting technology. During the initial cutting process, the cutting size of the straw is controlled within 20-50mm, breaking the previous dust phenomenon, realizing the environmentally friendly and clean production of straw, and completing the environmental protection of the production process;

[0011] Step 4: Sterilization and disinfection of raw materials. When the straw raw materials are harvested in the field, they will be parasitic on insect eggs, bacteria and other microorganisms. Use formaldehyde-free insecticide water and glue to mix and soak in a cyclone to remove the insects and eggs in the straw raw materials after the initial cutting. After the insects and eggs are removed, use a combination of red and blue ultraviolet rays to sterilize and disinfect;

[0012] Step 5: wall breaking. After the straw raw materials are sterilized and disinfected, the initially cut straw raw materials are passed through sieves of different apertures according to different types and lengths, and the wall is broken using a cylindrical crushing and kneading machine;

[0013] Step 6: Fiber-grade mixing and adding glue for mixing. After the wall breaking is completed, wheat straw, rice straw and soybean straw are blown into the mixer in a proportion of 1:1:3 by suspension and mixed. After sufficient mixing and stirring in suspension, optical sterilization and insecticide treatment with red light and blue light ultraviolet light is performed. At the same time, the organic and inorganic hybrid resin glue in the formula is automatically metered and mixed thoroughly.

[0014] Step 7: The materials are suspended and mixed again, and the inorganic nano-hybrid resin is sprayed in a special container with a wall rotating shape, and the centrifugal rotation technology is used to disperse and mix in a ratio of 1:0.25;

[0015] Step 8: Compression molding: the material is squeezed out by a double-tube pressing wheel, and the temperature is set at 200 degrees Celsius. The material is rotated at a low speed to directly mix the high-temperature airflow with the material, so that the material is heated evenly. Then the material is evenly added into a special mold through an automatic metering feeder, pressurized and heated to cure at high temperature, and then stamped, welded and bonded to obtain the required sheet and profile.

[0016] Step 9: Inspection and storage. After the inspection and testing are qualified, the products are packaged and stored.

[0017] Preferably, the raw materials in step 1 are divided into two types, one is bale material and the other is bulk material.

[0018] Preferably, the material screening in step 2 utilizes a magnetic field formed by electromagnetic principles to absorb iron from the straw, and at the same time a screen is provided below the raw material to blow away the soil using the principle of wind selection.

[0019] Preferably, in step five, a drying operation may be performed after the wall breaking treatment to remove moisture from the straw raw material.

[0020] Preferably, the mold in step eight is hemispherical, simulating the honeycomb principle to enhance the load-bearing and impact resistance of the box, the mold size is set to several scale sizes, and the thickness of the mold is set to several specifications such as 8mm, 6mm, and 4mm.

[0021] Preferably, the defective products detected and tested in step nine are recovered and reprocessed.

[0023] (III) Beneficial effects

[0024] Compared with the prior art, the present invention provides a nano-straw environmentally friendly packaging box and a preparation process thereof, which has the following beneficial effects:

[0025] 1. The nano-straw environmentally friendly packaging box and its preparation process take various types of straws as the basis and mix them in proportion, and then go through a series of processing processes to prepare the packaging box by welding and gluing with nano-inorganic hybrid resin. It not only solves the ecological problem of traditional carton boards consuming a large amount of wood pulp, but also solves the problem of crushing the straw and returning it to the field, which affects the seeds falling on the straw and preventing them from germinating in the soil, thus leading to reduced production.

[0026] 2. The nano-straw environmentally friendly packaging box and its preparation process use a new type of nano-silicon inorganic-organic hybrid resin as a bonding resin, which is odorless, pollution-free, formaldehyde-free, and degradable, solving the problem of reducing carbon consumption and VOC emission pollution.

[0027] 3. The nano-straw environmentally friendly packaging box and its preparation process use straw sterilization and disinfection technology to solve the problems of insect eggs and bacteria breeding in the process of straw collection and storage, without any pollution to the packaging and the environment.

[0028] 4. The nano-straw environmentally friendly packaging box and its preparation process use green and environmentally friendly technologies such as adhesives and straw processing technologies, which solve the impact of packaging on the natural environment. At the same time, it can be recycled, and the final waste can be degraded in the soil and can also generate biomass electricity. BRIEF DESCRIPTION OF THE DRAWINGS
