Inorganic binder and preparation method thereof

Abstract

The invention provides an inorganic binder and a preparation method thereof, wherein the inorganic binder comprises the following solid components by weight: 30-90 parts of desulfurization ash, 5-10 parts of limestone, 5-10 parts of dolomite and 0.5-4 parts of a dispersing agent, the inorganic binder further comprises water, and a weight ratio of the solid components to the water is 1:(3-5). According to the invention, most of the used raw materials are from iron and steel sintering plant wastes and are matched with other easily available and low-cost agents, so that the inorganic binder is low in cost, and the purpose of treating of waste with waste is achieved; the pollutant emission in the use process of the binder is almost zero so as not to cause secondary pollution influence on the production of related enterprises and so as to effectively reduce the pollutant emission of enterprises; and the binder can be independently used, can directly enters the production system of a granulation enterprise without matching with other admixtures, and is high in reaction speed and high in efficiency.

Description

technical field [0001] The invention belongs to the technical field of solid waste recycling, and in particular relates to an inorganic binder and a preparation method. Background technique [0002] The binder used in conventional solid granulation is mostly purified bentonite, which causes serious secondary pollution during the production of raw materials and has a greater impact on the later performance of the granules. Moreover, the traditional organic binder needs to be combined with other additives. When used in conjunction with the agent, the bonding effect is poor, which seriously affects the production and pollution reduction of related enterprises. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides an inorganic binder and a preparation method. [0004] The specific technical scheme is as follows: [0005] An inorganic binder, the difference is that the inorganic binder comprises the following solid c...
