Qingdao University of Science and Technology has developed a new rubber isolating agent using "gutter oil"

Foreign aircraft have "drunk" bio-aviation oil made of gutter oil, and the R&D team of Qingdao University of Science and Technology has developed a new functional rubber isolator
using gutter oil.

Rubber isolator is a commonly used operational auxiliary in the rubber processing industry, the main function is to prevent the surface of rubber film or rubber semi-finished products from bonding to each other, so as to facilitate the operation
of the process.
The earliest isolator is made by dissolving silica gel in gasoline, which produces products that are highly toxic, harmful to human health, and prone to safety accidents such as explosions, so they were quickly replaced
by the second generation of isolators using talc as raw material.

Professor Yin Shumei of the School of Chemical Engineering of Qingdao University of Science and Technology introduced that although the cost of talc as raw material is low, this isolator is easy to precipitate in water, affecting the sealing performance of rubber products, and produces dust pollution in the production process, endangering human health and polluting the environment
.

Yin Shumei said that the new rubber isolator developed with gutter oil has excellent isolation effect
.
This technology is to remove impurities from gutter oil and carry out a series of chemical reactions at a certain temperature to obtain a water-soluble rubber isolator
.
This new liquid isolator uses gutter oil as a raw material and is less
costly.
At the same time, this isolator has no dust pollution in the operating environment during rubber production, and is an environmentally friendly functional rubber isolator
.

Experts said that due to the need for clean production, rubber products enterprises will gradually reduce or even stop using talc as raw material rubber isolator, and environmentally friendly rubber isolator with gutter oil as raw material will have broad market prospects
.
