Abstract
This paper describes a method to recycle waste polyurethane rubbers. Waste
rubbers after manufacturing rubber products and most of the used rubber
products have affected bad effects on the environment. In the case of larger
rubber products, the waste rubbers and the used products have been recycled.
However the waste rubbers of smaller rubber products and the used products are
not recycled and are incinerated. An aseismatic mat is one of the smaller
products and it is made of polyurethane rubber. The mats are manufactured a lot
in Japan, so a lot of waste rubbers occur and are incinerated. In order to recycle
the waste polyurethane rubbers, we created a composite cube as a structural
material by using the waste rubbers. The composite cube had 15mm on a side.
Unsaturated polyester was used as a matrix, and then the waste polyurethane
rubbers were put in the unsaturated polyester. The waste polyurethane rubbers
were minced and the minced rubbers were made into a ball. Some composite
cubes on different quantities of the rubbers were prepared. Static compression
tests were carried out with the composite cubes and with a cube made of only
unsaturated polyester. Comparing with the load-displacement curves, it has been
shown that a maximum load of the 0.1g-rubber-containing composite cube is
larger than that of the rubber-free cube. However it has been shown that a
maximum load of the 0.5g-rubber-containing composite cube is not larger than
that of the rubber-free cube. So it is possible that polyurethane rubber reinforce
unsaturated polyester, if the rubber is minced and is made into a ball and is used
in the appropriate contained amount.
