Embodiment Construction

[0014] The raw materials used in the self-insulation, energy-saving and waterproof block of the present invention are phosphogypsum, quicklime, dephosphorization and desulfurization catalyst, cement, hollow glass microspheres, methyl hydrogen-containing silicone oil waterproofing agent, mixed with water evenly, and formed by hydraulic ejection equipment. It is produced by non-calcined autoclave curing method.

[0015] The technical key of the phosphogypsum self-heating, energy-saving and waterproof block of the invention is the phosphorus removal and desulfurization of the phosphogypsum. The invention adopts quicklime, water, phosphorus removal and desulfurization catalyst hydrogen peroxide to react rapidly under the catalysis, and produces calcium pyrophosphate and calcium sulfate which are harmless to building blocks and the environment, thereby achieving the purpose of phosphorus removal and desulfurization. It reacts as follows:

Abstract

The invention relates to a production method for a self heat preservation energy-saving waterproof building block. The production method comprises the following technical steps: taking 5 to 7 portions of dephosphorized and desulfurized ardealite, 1 to 2 portions of quick lime, 0.02 portion of sodium silicate or soda, 1 to 2 portions of 42.5R slag cement, 2 to 3 portions of hollow glass micro-bead, 0.01 to 0.02 portion of water-proofing agent and 1-2 portions of water for one cubic meter of building block; carrying out the forming through a hydraulic ejection device after evenly mixing raw materials; and finally producing the building block through a calcination-free steam compression curing method. The discarded ardealite is taken as a main raw material, thereby turning wastes into the valuables. The process is simple; and the product has high strength, light weight, and the characteristics of heat preservation, energy conservation and water resistance and fire prevention. The building block can be widely applied to the building engineering.

Description

technical field [0001] The invention relates to a production method of a self-insulating building block in construction engineering, in particular to a production method for producing a self-insulating, energy-saving and waterproof building block by using phosphogypsum, a bulk by-product of the phosphorus chemical industry, as a raw material. Background technique [0002] At present, the rapid development of agriculture has promoted the rapid development of my country's phosphorus chemical industry. The resulting phosphogypsum has become the most discharged chemical gypsum in my country, with an annual discharge of about 20 million tons and an annual growth rate of more than 15%. Phosphogypsum, also known as calcium-sulfur waste residue, is an industrial by-product discharged from the production of phosphoric acid with phosphate rock (mainly composed of calcium fluorophosphate) and sulfuric acid as the main raw materials. For every 1 ton of phosphoric acid produced, 4 to 5 t...
