[0066] A preparation method of an environment-friendly recyclable building formwork includes the following steps:

[0067] S1: Collect waste plastics, clean, dry and crush them into particles.

[0068] S2: Add the plastic particles into a mixer, and add steel slag, wood chips, glass fiber, and plasticizer, and stir them evenly.

[0069] S3: Add the mixed raw materials into a high-temperature extruder to melt them, and then extrude them through a mold to form a template blank. After processes such as die head extension, cooling and shaping, and traction cutting, the central board 1 of the building formwork is made.

[0072] The diameter of steel slag particles is 3 - 5 mm, and the diameter of plastic particles is 3 - 5 mm. The plastic is mainly polypropylene.

[0073] The working principle of the environment-friendly recyclable building formwork and its preparation method provided by the present invention is as follows:

[0074] By adding steel slag to the raw materials of the building formwork, the overall strength of the central board 1 is improved, and wear-resistant plates 2 are bonded and fixed on both sides of the central board 1 to enhance the strength of the surface of the central board 1, so that the building formwork has higher impact resistance, is not easily deformed during use, increases the number of uses, and extends the service life.

[0075] During splicing, insert the first connection block 91 at the upper right corner of one formwork B into the installation cavity 81 at the upper left corner of formwork A and pass through the rectangular slot on the installation block 82 until it can no longer be inserted.

[0076] Then insert the insertion block 112 at the lower left side of formwork C into the installation slot 92 on the first connection block 91, and make the bottom of the first connection block 91 contact with the bottom of the inner wall of the installation cavity 81.

[0077] Then insert the second connector 10 at the lower right corner of formwork D into the accommodation cavity 111 at the lower left corner of formwork C and pass through the jack 113 on the insertion block 112 and the U-shaped block 84 in sequence until it can no longer be inserted. At this time, the fixing hole 85 corresponds to the limit hole on the second connector 10. Then insert the limiting rod 42 in the limiter 4 into the cylindrical hole 114, so that the limiting rod passes through the fixing hole 85 and the limit hole in sequence, and then enters the limiting groove 12 and compresses the silica gel pad 13. During the insertion process, the two stoppers 43 are inserted into the two inlet holes 115 correspondingly. When the limiting rod 42 compresses the silica gel pad 13, the two stoppers 43 are located inside the accommodation cavity 111. At this time, rotate 90 degrees to make the two stoppers 43 correspond to the positions of the card slots 117. Release the limiting handle 41. Through the elastic thrust of the silica gel pad 13, make the stoppers 43 located inside the card slots 117 to make it fixed stably.

[0078] Through the mutual cooperation and limitation among the installation block 82, U-shaped block 84, first connection block 91 and second connection block, only one limiting member 4 can be used to fix four building templates, with firm fixation and convenient operation;

[0079] When disassembling, by pressing the limiting handle 41, the limiting rod 42 compresses the silica gel pad 13, so that the blocking block 43 moves out of the card slot 117. At this time, rotate it by ninety degrees to make the blocking block 43 rotate to correspond to the access hole 115, pull out the limiting member 4, and then separate and remove the corresponding building templates, which is simple to operate.

[0080] Compared with the related technology, the environment-friendly recyclable building template and its preparation method provided by the present invention have the following beneficial effects:

[0081] By incorporating steel slag into the raw materials of the building template, the overall strength of the central plate 1 is improved, and wear-resistant plates 2 are adhesively fixed on both sides of the central plate 1 to enhance the strength of the surface of the central plate 1, so that the building template has higher impact resistance, is not easily deformed during use, the surface is not easily damaged, the number of uses is increased, the service life is extended, and steel slag is used to save energy and protect the environment;

[0082] When the building templates are spliced and installed, through the mutual cooperation and limitation among the installation block 82, U-shaped block 84, first connection block 91 and second connection block on different building templates, only one limiting member 4 can be used to fix four building templates, that is, the four corners of each building template can be connected to nine surrounding building templates, which is more integral, has high firmness, and is simple and convenient for both installation and disassembly.

[0083] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly.
