Description

Production method of nano shell powder plastic ingot

The present invention refers to a method for making nanoshell powder plastic ingots, in which the nanoshell powder is first coated with a dispersant layer and a graft copolymer layer, and then mixed into the plastic to melt and extrude into nanoshell powder. Technical field of plastic ingots.

The first press refers to the fact that in ancient times, the technology was limited, and cement was not a popular item. It was forced to use local oyster shells as a binder for building materials. It was as long as the Dutch rule in the 17th century. During the treatment period, oyster shells were artificially calcined into oyster ash, and then oyster ash was used to blend sugar water, glutinous rice syrup, etc. as adhesives, and used in traditional brick and stone combination. This shows that oyster ash is indispensable. Important building materials. In addition, in the construction and maintenance of old wooden boats, oyster ash mixed with tung oil must also be used to fill the crevices of the wooden boat so that it will not leak water, and it has both strong and durable characteristics.

Today, low-cost industrialized cement and plasticized raw materials have completely replaced oyster ash, making oyster shells useless. As a result, fresh oyster production areas have piles of unmanageable oyster shells, causing serious local problems. As a result, the civilians are forced to think about solutions. However, after research by private units and government agencies, there are many results of conversion of oyster shells:

1. Fertilizer: Because the oyster shell is rich in minerals and calcium carbonate, after the oyster shell is crushed, it is evenly sprinkled in the farmland and stirred to neutralize the alkalinity and become a fertilizer for improving the soil. Fruits will also put oyster flour to add nutrients.

Second, feed: If the oyster shell is ground into coarse particles, it can be used as feed for chickens and ducks. It is used as a basis for supplementing minerals and calcium carbonate after eating chickens and ducks, and to prevent the eggs laid by chickens and ducks from softening and cracking.

Third, food: If the oyster shell is ground into powder, it can be used as food for humans to provide nutrients for the body to supplement the minerals and calcium carbonate.

Fourth, the greening of the saline zone: the saline zone contains the seaside. In this area, oyster shells can be laid first, and then light soil can be laid on the oyster shells, and the oyster shells can only be dialyzed into the light soil with moisture upwards. It can completely prevent the salt from rising into the light soil. According to this, it is guaranteed that the light soil can be planted with green plants, flowers and trees that cannot withstand the salt.

Furthermore, it has been found through research that after calcination of oyster shells, calcium carbonate will be converted into calcium oxide with antistatic and anti-ultraviolet effects. The calcium oxide chemically reacts with water molecules in the air to produce an excellent antibacterial activity. Oxygen, and then, when the calcined oyster shell is ground into fine nano-shell powder, the fine nano-shell powder is added to plastic to make a sea wool yarn 100. If sea wool yarn 100 wants to achieve warmth, sea wool yarn 100 It must be drawn into a hollow in the middle, and the sea wool yarn 100 has the characteristics of anti-static and anti-ultraviolet due to the addition of fine powder of nano oyster shell. However, please refer to No. M450574 for the production of sea wool yarn 100, which refers to a sea wool yarn 100 manufacturing device, which puts sea wool yarn material 110 into the barrel 10 of the extruder 20 and melts and extrudes into sea wool yarn 100 thick yarn The thick filaments are subdivided into sea wool yarn 100 filaments by pulling out through the gear pump 30 and then passing through the porous spinning nozzle in the spinning nozzle module 40. The sea wool yarn raw material 110 is mainly composed of PET, fine powder of nano oyster shell, and dispersant (PE). However, the entire content of the M450574 case only discusses the composition ratio of sea wool yarn 110. However, the fine powder of nano oyster shells has the problem of sedimentation or aggregation into larger particles in the melted PET. Therefore, when the sea wool yarn 100 is extruded into filaments, the fine powder of nano oyster shells aggregated into larger particles will cause The reason for the breakage of sea wool yarn 100 (as shown in case No. M450574, the other unmarked names are not drawn Out).

In addition, as shown in the content of No. I586868, the addition of fine powder of nano oyster shells is also limited to the composition of the warmth 5, and its additives include: additives 1, first granular material 2, radiation Mineral 11, calcium silicate 12 and marine biological calcium 13 (marine biological calcium 13 is the fine powder of nanometer oyster shell) mixing composition and proportion adjustment problem, so it can be seen that the content of No. I586868 still does not solve the problem of nanometer oyster. The settlement or agglomeration scheme of shell fine powder in the composition (as shown in the case No. I586868).

The inheritance is the use of ancient oyster shells and the current research results. The results have better greening effects in fertilizer, feed, food and salt areas. As for the sea wool yarn 100 and the warmth 5 components of the industrialized fiber, the technology still needs to be settled or agglomerated, and the current industrial application is limited to the fiber, which actually wastes the calcined oyster shell. Anti-static and anti-ultraviolet efficacies. Therefore, thinking about how to re-use and highlight the value of oyster shells is already the first research department for industrial applications (as shown in cases No. M450574 and No. I586868).

In view of the above, it is known that the conventional oyster shells have serious limitations in the scope of use in industrial applications, as well as sedimentation or agglomeration problems in the industrial fiber production process. Therefore, the inventors are urged to expand industrial applications and eliminate sedimentation. Or the direction of agglomeration was researched and developed, and after the inventors of this case, after many considerations, it was thought that the use of dispersant and graft copolymer to wrap a nanoshell powder is the best.

The preparation of the nanoshell powder plastic ingot of the present invention includes: first selecting a suitable shell, washing the surface of the shell until it is clean, and then drying the shell, and calcining the shell into shell ash after drying. The ash is ground into nanoshell powder, and then a layer of dispersant is wrapped on the surface of the nanoshell powder, and the nanoshell powder The rice shell powder is wrapped with a graft copolymer layer outside the dispersant layer. The surface of the graft copolymer layer is distributed with protruding grafts. Then, the nano shell powder is placed in a plastic ingot making machine and mixed Plastic, in the plastic ingot making machine, the nano shell powder and the plastic are uniformly melted and then extruded into the nano shell powder plastic ingot.

The mixing ratio of the nanoshell powder of the present invention is between 1% and 30%, and then, the mixing ratio of the plastic is between 70% and 99%. Then, the plastic includes: a thermosetting plastic , One polyvinyl chloride, one polyethylene, one polystyrene, one polypropylene, one polymethyl methacrylate, one acrylonitrile-butadiene-styrene copolymer, one nylon, one glass fiber reinforced plastic.

The purpose of the present invention is that the nanoshell powder plastic ingot can be selected from various plastics, so that the nanoshell powder can actually expand the scope of industrial application, and in order to eliminate the conventional settlement or agglomeration problem, it is The surface of the rice shell powder is wrapped with a dispersant layer to prevent the nano shell powder from having no settling problems. At the same time, the grafting on the surface of the graft copolymer layer prevents the actual benefits of the nano shell powder without agglomeration.
