Abstract
The invention provides a baking-free brick prepared by using yellow phosphorus slag and modified phosphogypsum as raw materials and a preparation method thereof. The industrial waste yellow phosphorus slag and the modified phosphogypsum are used as basic raw materials, sand and cement are added into the raw materials, and the mixture in a weight ratio is prepared into a finished product by processes of crushing, proportioning, mixing, stirring, high-pressure shaping, stripping, steam curing and the like. A large amount of yellow phosphorus slag discharged by the yellow phosphorus industry and a large amount of phosphogypsum discharged by the phosphoric acid industry are comprehensively utilized, and meanwhile, various environmental pollutions caused by long-term stacking of the yellow phosphorus slag and the phosphogypsum are reduced. The baking-free brick prepared from the yellow phosphorus slag and the phosphogypsum has the advantages of high utilization rate of industrial waste slag, high consumption, simple production process, short production period, low cost, environmental protection and energy conservation; and the brick meets the national standard requirements for baking-free common bricks, and is a novel environment-friendly building material. The steam curing is performed on the formed brick blank so as to shorten the curing time, improve the compressive flexural performance of the brick and facilitate large-batch production.
Description
Technical field
The present invention relates to a kind of is the non-burning brick method of feedstock production with yellow phosphorus slag and modified ardealite.
Background technology
China's land area reduces year by year, and land resources is more and more in short supply, can consume a large amount of non-renewable land resourcess owing to produce clay brick, has not met industry policy, so China prohibited the production clay solid brick in 2000.Various flyash, carbide slag, casting slag, the sandstone etc. of utilizing arise at the historic moment with brick as the building materials of alternative materials.
Phosphogypsum is the by product that produces in the Wet-process Phosphoric Acid Production process, and staple is CaSO

2Chemical ingredientss such as O.It is raw material that Electric Cooker phosphorus needs Rock Phosphate (72Min BPL), and because of various places Rock Phosphate (72Min BPL) grade is different, wherein the difference of component usually can cause SiO in the yellow phosphorus slag
2, CaO, F, Al
2O
3Content etc. chemical ingredients is different.Every production 1t yellow phosphorus approximately will discharge 8～10t waste residue; According to incompletely statistics; The quantity discharged of yellow phosphorus slag is 1078～1,300 ten thousand t/a in the world, and so big quantity discharged all air storages of major part except that the small portion regenerated using had both taken tract; Pollute environment, again human health has been caused harm.
China was studied the comprehensive utilization of phosphorus slag since the seventies in last century; Mainly utilize yellow producing cement with phosphatic slag (make cement raw material, make cement admixture), produce compound manure, but consumption is few, utilization ratio is also little; Other utilize the aspect to utilize various material of construction such as yellow phosphorus slag system wall body brick, pottery, lagging material, refractory materials in addition; But on the whole, the yellow phosphorus slag also is not fully used, and its utility value is still waiting better exploitation.
Domestic to the yellow phosphorus slag be the non-burning brick relevant report of feedstock production also seldom; At the Chinese patent publication number is to disclose a kind of " yellow phosphorus slag solution is produced the method for baking-free lightweight fireproof brick " among the CN101113102A; It is to get yellow phosphorus slag that granularity is 2～5mm, high-alumina cement, aluminium stone flour according to 10～15: 0.5～1.5: 0.3～1 weight ratio adds after suitable quantity of water mixes; Adopt non-baking brick machine to process shaped brick, conventional maintenance makes after the demoulding.The shortcoming of this method is: higher relatively as the cost of tackiness agent with high-alumina cement and aluminium stone flour, secondly, the adobe curing time is longer, is unfavorable for industrial production.
Summary of the invention
The objective of the invention is to overcome and above-mentionedly existing add the deficiency of protecting, what provide that a kind of yellow phosphorus slag and modified ardealite make is non-burning brick and preparation method thereof.This non-burning brick raw material is easy to get, and the industrial residue utilization rate is high, and production technique is simple, the cycle is short, and product strength is high, quality is good, has good economic benefits and social benefit.
Technical scheme of the present invention is: it is non-burning brick that yellow phosphorus slag and modified ardealite prepare, and prepares by following materials of weight proportions:
Yellow phosphorus slag 65～75%
Modified ardealite 25～35%
Sand 5～10%
Cement 3～5%
Water 5～10%.
Mix flyash, unslaked lime etc. in the said modified ardealite as properties-correcting agent, coldcondition promptly carry out anhydrous calcining modification under 200～300 ℃ and, fluorine content is lower than 0.1% in the modified ardealite, phosphorus pentoxide content is lower than 0.3%.
Said non-burning brick be solid standard brick or Brick with blind hole or perforated brick.
A kind of yellow phosphorus slag and modified ardealite prepare non-burning brick method, comprise pulverizing, batching, mix stirring, high-pressure molding, the demoulding, vapor cure operation, it is characterized in that making finished product by following step:
A, yellow phosphorus slag, modified ardealite and sand are crushed to granularity less than 3mm with sample pulverizer, press: yellow phosphorus slag 65～75%, modified ardealite 25～35%, sand 5～10%, cement 3～5%, water 5～10% is prepared burden;
B, the material that will prepare carry out thorough mixing and stir in cement mortar mixer;
C, well-mixed batching is pressed into adobe with pressure forming machine;
D, adobe is positioned over the vapor cure case under 60～80 ℃, carries out vapor cure 6～8 hours, obtain said product.
Mix flyash, unslaked lime etc. in the said modified ardealite as properties-correcting agent, under coldcondition (200～300 ℃) carry out anhydrous calcining modification and, fluorine content is lower than 0.1% in the modified ardealite, phosphorus pentoxide content is lower than 0.3%.
Advantage of the present invention is:
(1) adopt anhydrous low temperature calcination method that phosphogypsum is carried out modification; Both eliminated in the phosphogypsum various impurity to the influence of its follow-up use, and made the modified ardealite performance reach the requirement that building materials use, the secondary pollution that has produced when having avoided methods such as washing processing phosphogypsum again; Simultaneously; Carry out modification at a lower temperature, both met energy-saving and cost-reducing policy, help the realization and the development of industrialization again.
(2) of the present invention non-burning brick, the utilization ratio of solid waste is 87～93%, and utilization ratio is high, utilization is big, turns waste into wealth, and belongs to novel environmental-friendly construction material.
