TECHNICAL FIELD
[0001] The utility model belongs to the field of regeneration particles, especially relates to a novel modified regeneration plastic rice. BACKGROUND
[0002] Plastic rice is the common name of regeneration particles, and the regeneration plastic particles belong to the category of plastic particles, and the regeneration plastic is the plastic produced by the screw machine from the recycled new material or waste plastic, and is cut into granular by the pelletizer; the recycled plastic is broken into pieces, cleaned, and the dust, sand and other foreign matters adhered to the surface are removed, and after drying, the plastic pieces are heated to a molten state and extruded by the screw extruder; the molten plastic leaves the die head of the screw extruder and becomes a strip, and after water cooling / air cooling, the plastic strip is quickly hardened into a plastic strip; and the cutter head of the pelletizer continuously cuts the plastic strip to form the plastic rice required.
[0003] The plastic rice can be used as raw material for production again, and the technical personnel mixes the plastic rice with various fillers according to the requirements, and then puts them into the screw extruder for heating and mixing, so that the required plastic products can be obtained after injection into the mold; and different fillers can be selected according to the processing requirements to endow the plastic products with properties such as toughening, ultraviolet resistance, fire resistance, flame resistance, and reinforcement.
[0004] The plastic rice can be used for manufacturing plastic products again after being heated to a molten state, and various fillers represented by plasticizers, toughening agents and reinforcing agents are added to the plastic to improve the properties of the plastic; the fillers are usually in the form of powder, and if the powder is added to the molten plastic rice, it is easy to agglomerate into a group, and a long time is needed to uniformly disperse the fillers. Therefore, the plastic rice needs to be fully mixed with the powder before being heated, but since the particle diameter of the plastic rice is large and the particle diameter of the powder is small, the powder is easy to pass through the gap of the plastic rice after mixing, and finally falls to the bottom of the mixture and accumulates in a large amount; at this time, only a small amount of powder adheres to the surface of the plastic rice, and the mixing degree of the powder and the plastic rice in the mixture is low, so even after pre-mixing, a long time of stirring is still needed; this is because the combination of the powder and the plastic rice is poor, and the two phases are separated to a high degree, and the agglomerated powder is easy to agglomerate into a group, so improving the combination of the powder and the plastic rice has a positive significance for shortening the heating and stirring time and improving the production efficiency.
