Embodiment 1

[0035] A kind of step that prepares mobile phone frame with walnut shell-based ecological composite material is as follows:

[0036] Step 1. According to the material texture design plan, cut the walnut into four parts along the direction parallel to the central axis, and remove the kernels;

[0037] Step 2, placing the cut walnut shells evenly and densely in the mold with the cut section facing upwards;

[0038] Step 3: Heat the alicyclic epoxy resin with a volume ratio of 1:3 to the walnut shell to 155°C, and pour it evenly into the mold;

[0039] Step 4. Apply a positive pressure of 35 MPa to the mold to remove air holes and cool to form;

[0040] Step 5. Machine the plate according to the drawing, polish the edges and corners around it, and cut out the groove for placing the mobile phone, such as figure 1 .

Embodiment 2

[0042] A kind of cubic type walnut shell handicraft prepared with walnut shell-based ecological composite material as the main body is as follows:

[0043] Step 1. According to the material texture design plan, cut the walnut into four parts along the direction parallel to the central axis, and remove the kernels;

[0044] Step 2, placing the cut walnut shells evenly and densely in the mold with the cut section facing upwards;

[0045] Step 3: Heat the plexiglass with a volume ratio of 1:2 to the walnut shell to 240°C, and pour it into the mold evenly;

[0046] Step 4. Apply a positive pressure of 25 MPa to the mold to remove air holes and cool to form;

[0047] Step 5, machine the plate according to the drawings to form an outer frame;

[0048] Step 6. Inlay activated carbon blocks in the outer frame, and connect tassels to the outside, such as figure 2 and Figure 2a , 2b , 2c, the handicraft component includes a frame 2 and a mosaic block 1 conforming to the shape of ...

Embodiment 3

[0051] A walnut-shell-based ecological composite material is a pier-shaped walnut-shell handicraft prepared as a main body. The steps are as follows:

[0052] Step 1. According to the material texture design plan, cut the walnut into the required shape and remove the kernel;

[0053] Step 2, place the cut walnut shells in the mold;

[0054] Step 3: Heat the rosin with a volume ratio of 1:1 to the walnut shell to 180°C, pour it into the mold evenly, and stir;

[0055] Step 4. Apply a positive pressure of 10MPa to the mold, remove air holes, and cool and form;

[0056] Step 5: Inlay crystal blocks on walnut shells, such as image 3 and Figure 3a , 3b , 3c, the handicraft component includes a frame 2 and a mosaic block 1 conforming to the shape of the frame 2; the material of the mosaic block 1 is crystal, and the quantity is two, which are cast in a mould. The frame 2 is in the shape of a pier, and its material is a walnut shell-based ecological composite material, which i...

Abstract

The invention relates to a walnut shell based ecological composite structure material and a preparation method thereof. The method comprises the following steps: (1) simply processing walnut shells byremoving kernels and drying; (2) arranging the dried walnut shells in a mold; (3) heating an additive, and pouring the additive into the mold; (4) in the additive cooling process, carrying out stamping, air hole removing and cooling forming on a material in the mold; and (5) taking out the material from the mold and machining the material to obtain the walnut shell based ecological composite structure material. Compared with the prior art, the method has the advantages that the process is simple, the universality is high, the method can be popularized in walnut original places, walnut shell productivity is consumed, and economic development of villages and towns is promoted.

Description

technical field [0001] The invention relates to the technical field of ecological composite material processing, in particular to a walnut shell-based ecological composite structural material and a preparation method thereof. Background technique [0002] Walnuts are one of the world-renowned "four major dried fruits". Walnut kernels are rich in nutrients, and contain various trace elements and minerals such as calcium, phosphorus, and iron necessary for the human body. They are one of the nut foods loved by the common people. In 2016 alone, the global walnut production exceeded 7.2 million tons, and my country's output exceeded 1 million tons. [0003] In addition to walnut kernels, walnut shells also have high nutritional value. Dried walnut shells have the functions of sterilizing and reducing inflammation, reducing pain and swelling, clearing psoriasis, and treating ulcers. In addition, the walnut shells of some special varieties such as iron walnuts and pecans also ha...
