Dihydrate desulphurization gypsum rubber reinforcing agent

Abstract

The invention discloses a dihydrate desulphurization gypsum rubber reinforcing agent, belonging to the field of rubber additives. The rubber reinforcing agent is prepared from 89-90 parts of dihydrate desulphurization gypsum and 10-12 parts of composite coupling agent through grinding. The composite coupling agent comprises a silicone coupling agent, a titanate coupling agent, an aluminate coupling agent, triethanolamine and a diluent agent. After the silicone coupling agent, the titanate coupling agent, the aluminate coupling agent and the triethanolamine are compounded according to the weight ratio of 1:2:2:1, and the mixture is diluted and enlarged by using 4 times of diluent agent. Compared with the prior art, the dihydrate desulphurization gypsum rubber reinforcing agent is directly prepared from dihydrate desulphurization gypsum as a main material and has the characteristics of energy saving, environmental protection, low material cost and the like.

Description

technical field [0001] The invention relates to a rubber additive, in particular to a dihydrate desulfurized gypsum rubber reinforcing agent. Background technique [0002] Dihydrate desulfurization gypsum is a by-product of desulfurization in power plants. According to the statistics of China Electricity Council, the installed capacity of flue gas desulfurization in thermal power plants in my country is close to 300 million kilowatts, of which limestone-gypsum wet desulfurization process accounts for more than 90%. By the end of the "Eleventh Five-Year Plan", my country will have 300 million kilowatts of coal-fired generating units equipped with limestone-gypsum desulfurization facilities. According to a 300MW unit burning coal with a sulfur content of 1%, it will run for 5000-6000 hours per year. , will produce 45,000 to 50,000 tons of desulfurized gypsum, and then my country will produce 50 to 60 million tons of desulfurized gypsum every year. According to the prediction of...
