Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
The present invention provides a plastic injection molding machine which is excellent in productivity since plastic resin is injection-molded after being subjected to a separate coating process and can be recycled without separating or filtering harmful paint materials, The present invention relates to an ABS resin, an ABS resin material pellet, and a method for producing the ABS resin. The resin composition comprises 96 to 99% by weight of an ABS resin and 4 to 1% by weight of an aluminum metal powder additive, The method for producing the resin composition will be described in more detail.
a. In the mixing step S10,
In this step, the starting material is placed in a
The ABS resin (acrylonitrile-butadiene-styrene resin) which is the main component of the resin composition has three components of acrylonitrile (A), butadiene (B) and styrene (S), and styrene- acrylonitrile copolymer Such as SBR and NBR, is excellent in impact resistance, chemical resistance, and weather resistance. In particular, the ABS resin is excellent in impact resistance, chemical resistance, weather resistance, and particularly in molding and coloring such as injection molding and extrusion molding. And is excellent in processability. In addition, it has good compatibility with other resins and may be used by mixing vinyl chloride with polycarbonate or the like.
On the other hand, the aluminum metal powder, which is an additive of the resin composition, has a particle size of 5 to 60 탆. When the particle size of the aluminum metal powder is 60 탆 or more, the surface of the product to be molded is not uniform. When the particle size of the aluminum metal powder is 5 μm or less, it is difficult to produce the aluminum metal powder, which increases the manufacturing cost and is not suitable.

The physical properties of the pellets produced by the method for producing ABS resin pellets containing aluminum powder according to the present invention and the conventional ABS resin pellets not containing aluminum powder were measured. The results are shown in Table 1 Respectively.
As shown in Table 1, the physical properties of the existing ABS resin pellets and the ABS resin pellets including the aluminum powder according to the present invention show a large difference only in the elongation, It is confirmed that the present invention is applied to various products using existing ABS resin pellets.
That is, in the ABS resin, the ABS resin material pellet including the aluminum powder of the present invention and the manufacturing method thereof, the aluminum resin powder is mixed with the ABS resin and is produced in the form of pellets, and the injection product, It is easy to recycle because it is not painted on the appearance of the product, and since there is no big difference in the properties with the existing ABS resin pellets, And the product molding apparatus used in the present invention can be used as it is.
