Description

Filling the wall using waste plastic drainpipe and a method of manufacturing}

The present invention relates to a filling wall sewer pipe using waste plastic and a method of manufacturing the same, and more particularly, to a filling material for reinforcing strength therein by using waste plastic made of plastic such as waste vinyl, and the outer diameter of the filler The present invention relates to a filling wall sewer pipe using waste plastic and to a method of manufacturing the same.

Conventional recycling methods for waste plastics include the use of waste plastics as a filler or additive in the blending of plastics, i.e. using a small amount of waste plastic as a filler or additive, or a new kind of waste plastic. When used as a resin, a one-dimensional reuse method of mixing a certain amount of waste plastics, and the method of using as a filler and additive is limited in the type of resin that plays a role, so only a fraction of the waste plastic can be used, In addition, the waste plastic that can be used also has a problem such as compatibility with new resins, the use range is reduced and limited.

In addition, when used as an additive, the amount of use is generally small, and its use is also limited. The method of adding waste plastic when using the same type of resin is the main purpose of lowering the price of the product. There is a disadvantage that can not be used in the resin, and also because it is used only in the range that the mechanical properties of the new resin does not fall, the amount of use is also a small amount and there is a disadvantage of such restrictions.

There is a case in which melt kneading is not carried out by sorting waste plastic in another way, but the waste from the incinerator is mixed with burned ash and molded into pellets. However, this is a plastic that is incompatible with each other because various waste resins are mixed. The effectiveness of the resin is questionable, and even if it is used, if there is no compatibility among them, this part may not be widely used due to the disadvantage that the mechanical properties as a recycled resin that degrades the bond strength of the resin do not appear above the usable level. It was.

In addition, there is a case where the method used to reduce this phenomenon is immobilized by mixing polyethylene wax in the ash of waste plastic and incinerator, but this also has no basis for chemically connecting the waste plastic to each other, and rather low molecular weight. As the wax enters, there are disadvantages in that the mechanical properties are lowered and the price is increased.

In the case of mixing and molding various waste plastics, the profile 12 is coated with the outer diameter of the filler 11 made of waste plastic, as well as mechanical properties, thereby providing an advantage that the filler 11 is not exposed due to the profile 12. However, the bonding force between the filler and the profile is weakened, so that a disadvantage of deteriorating mechanical properties occurs.

And in the case of the filling wall sewer pipe is formed by coating the profile (12) on the filler material 11 is mainly used for sewage, but the sewer is divided into sewage and rainwater for the purpose of the pipe to see only the appearance of the filling wall sewer pipe The disadvantage of not being able to accurately grasp has arisen.
