Method for devulcanization of waste rubber and composition
一种把橡胶去硫化的机械/化学方法和合成物，其可维持大分子，并使硫变成钝态，供以后再硫化，如图1所示，其具成本效益、环保，及可生产高质量去硫化橡胶以取代原橡胶。废橡胶被切碎、压碎和去除金属。当切碎废橡胶粒子倒入两个进一步压碎粒子的辊轧机时会加入改性合成物。改性合成物为一质子供体、一有机酸、一抑制物和一摩擦剂的混合物。粒子会经过最少10组辊。 Mechanical/chemical method and composition for de-vulcanization of rubber maintains the macromolecules, renders sulfur passive fo...

Mechanical/chemical method and composition for de-vulcanization of rubber maintains the macromolecules, renders sulfur passive for later re-vulcanization, is cost effective, environmentally friendly and produces high quality de-vulcanized rubber to replace virgin rubber. Waste rubber is shredded, crushed and metal-removed. Modifying composition is added as the particles of shredded waste rubber are poured between two rollers that further crush the particles. The modifying composition is a mixture of (1) a proton donor that selectively breaks the sulfur bonds and renders the sulfur passive, (2) a metal oxide and (3) an organic acid that build new bonds between macromolecules for later re-vulcanization, (4) an inhibitor that prevents re-attachment of sulfur radicals with each other before the proton donor attaches itself to the sulfur and (5) a friction agent that prevents sliding of the waste rubber between the rollers. The particles are subjected to at least ten sets of rollers. |
