[0013] The present invention is based on the guiding idea that phosphorus-containing inorganic polymers can be used for the treatment and storage of hazardous wastes and the reuse of harmless wastes. waste for reuse. Specifically, the present invention relates to a phosphorus-containing inorganic polymer, including oxides or hydroxides of the first, second, and third main group metals, or oxides or hydrogen oxides of the fourth, fifth, and sixth-period transition metals Oxides, or the pretreated powdered reactants belonging to these compounds, and slags of domestic and industrial wastes, wherein the first mixture of the powdered reactants and boric acid is composed of the The slurry made of the first mixture and phosphoric acid or phosphate is the second mixture, a polymer slurry made of the second mixture and the slag of domestic and industrial wastes, wherein the The first mixture, the weight ratio of boric acid in the mixture to the powdered reactant is: (5-15): (95-85); t...

example 1

[0025] Example 1, an experimental example about the treatment and utilization of slag in Chengde Iron and Steel Company:

[0026] The gray-black slag from the slag mountain and the mixed oxide (content of Fe2O3 19%, MgO 67%, SiO2 14%, etc.) The concentration of the product is 95%, diluted to 50% before use) and boric acid, mixed according to the aforementioned ratio and processed according to the aforementioned process. No change in appearance.

example 2

[0027] Example 2, an experimental example about the treatment and utilization of waste residue from Xiangxi Electrolytic Manganese Plant:

[0028] The gray-green waste slag from the electrolytic manganese plant, mixed oxides (contents of Fe2O3 19%, MgO 67%, SiO2 14%, etc.) The concentration of the purchased product is 95%, diluted to 50% before use) and boric acid, mixed according to the aforementioned ratio and processed according to the aforementioned process, the resulting product is as hard as magnetism, and the appearance porosity is close to zero. and no change in appearance.

Abstract

A phosphorus-contained inorganic polymer and its production are disclosed. The polymer consists of oxide or hydroxide of the No.1, No.2 and No.3 main family metals or oxide or hydroxide of the No.4, No.5 and No.6 periodic transient metals or powdery reactant, fag-ends of boric acid and industrial waste, phosphoric acid or phosphate. The process is carried out by pre-treating for powdery reactant, mixing boric acid, phosphoric acid or phosphate with pretreated powdery reactant sequentially and proportionally to form the No.1 and No.2 mixture solution, adding fag ends into the solution, agitating to form slurry, filling it into mould, curing and forming.

Description

technical field [0001] The invention relates to an inorganic polymer material in the fields of construction, environmental protection, etc. and its preparation method, especially a phosphorus-containing inorganic polymer and its preparation method Background technique [0002] In the existing waste treatment technology, when the inorganic curing agent represented by cement is used to treat waste, the product has high strength and good stability, but the treatment efficiency is low. Usually, the proportion of waste in the product is below 40%, and when the organic curing agent represented by high molecular polymer is used to treat waste, the treatment efficiency is high but the stability of the product is poor. And about the report of condensate technology, there are many disclosures in published patent documents and information and communications in the field of building materials, especially the advent of alkali-activated slag cement guided by the theory of alkali excitatio...
