Problems solved by technology

Although the oil-absorbing material has been modified, its oil-absorbing effect and mechanical properties have been greatly improved, but the material can be reused during use. Afterwards, when the oil-absorbing material absorbs oil for the second time, its oil absorption and mechanical properties cannot reach the required level.

Abstract

The invention provides a reinforcing filler, high oil absorption resin and a preparation method of the high oil absorption resin. The reinforcing filler is made mainly with modified lignin powder andglass fiber powder in a specific ratio; the reinforcing filler is added to the high oil absorption resin in a certain ratio; the results of the above preparation process show that high oil absorptionrate can be still maintained in secondary oil absorption, the high oil absorption rate is truly secondarily recycled, and the treatment cost for surface oil on oily wastewater is reduced directly. Theaddition of the reinforcing filler is controlled strictly within a certain range in order to ensure its secondary oil absorption performance. The high oil absorption resin prepared herein has a higher secondary oil absorption rate; the defect of the prior art that oil absorption rate of the high oil absorption resin decreases greatly during secondary sue; the reinforcing filler has a good application prospect and high market value.

Description

technical field [0001] The invention relates to a high oil-absorbing material for oily sewage treatment, in particular to a reinforcing filler, a high oil-absorbing resin and a preparation method thereof. Background technique [0002] With the continuous development of my country's modern industry, the use of petroleum and various oil products in daily life is becoming more and more frequent, and the use of oil products is also increasing year by year. However, a large amount of oil in daily life is discharged into underground sewage. The treatment of sewage has caused great difficulties. In addition, if the oily sewage is discharged directly without treatment, it will not only further affect the clean water body, but also affect the normal survival of aquatic organisms. The oil in the oily sewage floats on the water surface and forms an oil film to prevent oxygen in the air. It normally enters the air, which in turn affects the oxygen content in the water, thereby affecting...
