All vulcanized powder rubber project won the gold medal of China

In November 8th, at the thirteenth China Patent Award conference, the Beijing Chemical Research Institute "completely vulcanized and controllable particle size powder rubber and its preparation methods and uses" won the gold medal of the Chinese patent。


This year's China patent award has selected 15 gold award items. The "completely vulcanized and controllable particle size powder rubber and its preparation methods and uses" has high technical level, good economic and social benefits. It stands out from the millions of effective patents and 697 outstanding patent projects, ranking the top of the 15 Chinese patent gold medal projects, becoming the independent innovation and acceleration of the Beijing Chemical Research Institute. An excellent example of the industrialization of intellectual property. 


"Fully vulcanized controllable particle size powdered rubber and its preparation methods and uses" is the patented patent of the North China Institute of powder rubber, and was granted the Chinese patent authorization in 2004. The patented patent also applied for us patent and entered the 12 countries and regions in Europe, Japan and other countries through PCT international application. At present, patents are obtained in other countries and regions except Japan. 


The invention provides a fully vulcanized controllable particle size powder rubber with a diameter of 50~2000nm, and a preparation method and application thereof. The ultrafine rubber particles are easily dispersed in the polymer materials at the primary particle size, and can maintain the elastic properties of the rubber. The modified polymer materials have excellent properties and can be used in the preparation of high performance modified polymer materials and low cost and efficient auxiliaries. 


According to the patented technology, a pilot plant of "full vulcanized ultra-fine rubber particles" has been built at the scientific research base of the northern Academy of chemical technology with an annual output of 1000 tons. The product has been widely used in the manufacture of friction materials, epoxy resin modification, PVC modification, Polypropylene Modification and a variety of other polymer modified materials. So far, "fully vulcanized ultrafine rubber particles" has been applied in more than 200 domestic enterprises and enterprises in Japan and Thailand.
