According to reports, among many natural resources, forest resources are actually one of the most important assets in the earth's resources. In addition to nurturing a rich and diverse ecosystem of animals and plants, forest resources also provide various materials needed by humans and are closely related to human life. Therefore, How to improve the utilization rate, recycling rate and reuse rate of wood has become an important issue that countries around the world are eager to break through, in order to reduce the unnecessary waste of natural resources and effectively reduce the manpower and material resources required for residual material processing.

In view of this, in recent years, research on the preparation of polymer plastic biocomposites (woodplastic composite, WPC) from wood residues or fragments has attracted more and more attention around the world. The reason is that WPC can effectively utilize wood fiber residues.

However, there are still many problems in combining two or more raw materials with different properties through different processing methods. Among them, the biggest problem is that the difference in surface polarity between colloids often hinders the connection between the two. Chemical bonding.

In addition, in an atmosphere of increasing environmental awareness, the aforementioned WPC composite materials or other plastic composite materials still cannot be widely used or applied to people's daily life needs due to the many structural shortcomings and toxicity problems mentioned above.

Please refer to Figure 2. Based on the above-mentioned molding method of imitating wood nail-holding force, the present invention further provides a molding system 200 of imitating wood-like nail-holding force, which is applied to recycled plastic scraps and recycled materials 11 , the molding system 200 for imitating wood nail holding force includes: a crushing mechanism 21, an adding mechanism 22, a mixing mechanism 23, a granulating mechanism 24 and a molding mechanism 25.

Specifically, as shown in Figures 2-3, according to the crushing mechanism 21 of the present invention, the plastic scraps and recycled materials 11 are powdered to facilitate subsequent operations. The plastic scraps and recycled materials 11 are polystyrene. Mixtures of ethylene, synthetic rubber, emulsified synthetic rubber and elastomers copolymerized with styrene and butadiene. In some embodiments, the weight percentage of polystyrene is between 30% and 85%, the weight percentage of synthetic rubber is between 5% and 50%, the weight percentage of emulsified synthetic rubber is between 3% and 45%, and the styrene and The weight percentage of butadiene copolymerized elastomer ranges from 2% to 35%. However, the present invention is not limited to this. It should be further explained that due to the different proportions of polystyrene, synthetic rubber, emulsified synthetic rubber and elastomer copolymerized with styrene and butadiene in the plastic scraps and recycled materials 11 of the present invention, the imitation wood finished product can be made At 15 o'clock, the imitation wood product 15 will have uneven patterns on the same cross-section, achieving a texture like growth rings. At the same time, the outer surface of the imitation wood product 15 will also have uneven patterns, making the appearance of the imitation wood product 15 The surface has a rough feeling and forms a wood-like rough surface, achieving the effect of being close to the pattern and rough surface of real wood, greatly increasing the applicability of the present invention.

Furthermore, polystyrene allows the imitation wood product 15 to have rigidity similar to that of real wood. Preferably, the polystyrene includes general polystyrene and impact-resistant polystyrene. The impact resistance of impact-resistant polystyrene is better than that of general polystyrene. Therefore, impact-resistant polystyrene can further improve the imitation quality.

In addition, talcum powder can increase rigidity and improve the dimensional stability and temperature resistance of imitation wood products.

It is worth mentioning that since the plastic scraps and recycled materials 11 are in irregular shapes, such as blocks or sheets, it will be difficult for the user to perform various operations on the plastic scraps and recycled materials 11. Therefore, the crushing mechanism 21 can effectively crush the plastic scraps and recycled materials 11. The plastic scraps and recycled materials 11 are powdered, which greatly improves the efficiency of the molding system 200 of the imitation wood nail-holding force according to the present invention, but the present invention is not limited thereto.

Specifically, as shown in Figures 2-3, according to the adding mechanism 22 of the present invention, it is coupled to the crushing mechanism 21. The adding mechanism 22 adds a plurality of functional additives 12 to the mixed plastic scraps that are in a crushed state and recycled. In material 11, the functional additives 12 include organic stabilizers, coupling agents, thermal stabilizers, gelling accelerators, foaming agents, light absorbers, light calcium carbonate, colorants, toughening agents, and talcum powder. It should be further explained that in some embodiments, the percentage of the organic stabilizer ranges from 0.1% to 10%, the percentage of the coupling agent ranges from 0.1% to 5%, and the percentage of the thermal stabilizer ranges from 0.1% to 10%. The content is between 0.1% and 3%, the gelling accelerator is between 0.1% and 10%, the foaming agent is between 0.1% and 3%, and the light absorbing agent is between 0.1% and 3%. Between 0.1%-3%, the percentage content of the light calcium carbonate is between 3%-25%, the percentage content of the colorant is between 0.01%-2.5%, and the percentage content of the toughening agent is between 3%-10%, the percentage content of the talc powder is between 3%-25%. In this way, the functional additive 12 of the present invention, combined with the used plastic scraps and recycled materials 11, can effectively increase the flow rate of polystyrene, synthetic rubber, emulsified synthetic rubber and elastomers copolymerized with styrene and butadiene, so that Mixtures of polystyrene, synthetic rubber, emulsified synthetic rubber and elastomers copolymerized with styrene and butadiene can be used in subsequent molding machines. In addition, by adding an appropriate proportion of functional additive 12, the mixture can be effectively prevented from die expansion during subsequent injection molding or extrusion molding, and can reduce polystyrene, synthetic rubber, emulsified synthetic rubber and styrene. The interfacial tension between the elastomer copolymerized with butadiene and the adhesion of the interface are improved to stabilize the mixture into a wood-like shape. This can significantly improve the tensile strength and flexural modulus of the wood-like finished product 15 and impact strength and other mechanical properties, thereby producing imitation wood products with low cost and stable quality15.

Specifically, as shown in Figures 2-3, the mixing mechanism 23 according to the present invention is coupled to the adding mechanism 22. The mixing mechanism 23 is used to combine the pulverized plastic scraps and recycled materials 11 with these functions. The sexual additive 12 is stirred and mixed thoroughly to form the recycled raw material 13. The mixing mechanism 23 may be, but is not limited to, one of a high-speed mixer, a solar mixer, a horizontal mixer, and a vertical mixer. Preferably, the mixing mechanism 23 may be a high-speed mixer. More specifically, the method of mixing the base material can be to mix all the raw materials together at one time, or to mix them in stages, and there is no certain limit. Preferably, in some embodiments of the present invention, organic stabilizers, coupling agents, thermal stabilizers, gelling accelerators, light absorbers, light calcium carbonate, colorants, toughening agents, talc and After the plastic scraps and recycled materials 11 are mixed together, they are stirred at high speed for a predetermined time, and then a foaming agent is added to continue stirring and mixing. However, the present invention is not limited to this.

Specifically, according to the granulating mechanism 24 of the present invention, it is coupled to the adding mechanism 22. The granulating mechanism 24 makes the recycled raw material 13 after adding the functional additives 12 into granular plural polymers. Raw materials 14. In some embodiments, different granulation mechanisms 24 can produce different polymer raw materials 14 for different recycled raw materials 13 . For example, the granulation mechanism 24 can be a water strand granulator or a die-cut granulator. etc., however, the present invention is not limited thereto.

Specifically, as shown in Figures 2-3, according to the molding mechanism 25 of the present invention, it is coupled to the granulation mechanism 24. The molding mechanism 25 directly melts the polymer raw materials 14 into a fluid state to form a polymer with a Imitation wood finished product with imitation wood nail holding power15. In some embodiments, the molding mechanism 25 can select different molding mechanisms 25 according to user needs. For example, the molding mechanism 25 can be one of an injection molding machine and a hot press molding machine. When an injection molding machine is used, it can be Achieve smaller and fine imitation wood finished products 15. However, due to the limitation of fluidity of the polymer raw material 14 itself, it is difficult to make larger imitation wood finished products 15 by injection molding. In this case, a hot press molding machine can be used. To form a larger imitation wood finished product 15, the user can choose which method is more appropriate according to their needs. The present invention is not limited to a specific molding mechanism 25.

In order to further understand the structural features, technical means and expected effects of the present invention, the actual implementation process of the present invention is described. I believe that this will provide a deeper and more specific understanding of the present invention, as follows:
