Abstract
Description
technical field
[0001] The invention relates to a high oil-absorbing resin and a preparation method thereof, in particular to a high oil-absorbing resin made from waste tire rubber powder and a preparation method thereof. Background of the invention
[0002] Traditional inorganic oil-absorbing materials (such as perlite, vermiculite, clay or diatomaceous earth) have basically been rarely used due to their low oil-absorbing efficiency. At present, organic oil-absorbing materials (such as polypropylene and polyurethane foam) are widely used in industry, but the production cost of these organic synthetic polymer oil-absorbing materials is high. The annual output of tires in the world is as high as 3 billion, and it is increasing at an astonishing rate of about 1 billion per year, with a scrap rate of 55.4%. In 1994, my country produced 50 million tires, 12.5 million were discarded, and the scrap rate was 25%. In 2001, my country's tire output reached 133.56 million pieces, ra...
