Abstract
The invention discloses a preparation method of a gypsum-based thermal insulating mortar. The preparation method comprises the following steps of: weighing 40-50 parts by weight of phosphogypsum as a cementing material, 10-15 parts by weight of yellow phosphorus slag powder, 5-10 parts by weight of cement, 30-35 parts of glass beads as lightweight aggregates and 1-2 parts of admixture as raw materials, mixing all the raw materials together and evenly stirring, thereby obtaining the gypsum-based thermal insulating mortar with the waste phosphogypsum and the phosphorus slags as the cementing material. The preparation method provided by the invention has the advantages of low energy consumption and low manufacturing cost, and also is capable of effectively utilizing the phosphogypsum and the phosphorus slags, high in product softening coefficient and excellent in quality; the preparation method is consistent with the policies of saving energy and reducing emission, and also capable of effectively utilizing industrial solid wastes such as the waste phosphogypsum and the phosphorus slags; therefore, the emission of wastes is reduced and the cultivated land is protected.
Description
Technical field
The present invention relates to a kind of preparation method of gypsum base thermal insulation mortar, particularly a kind of take residue phosphogypsum and phosphorus slag as the gypsum base thermal insulation mortar preparation method of main gelling material, belong to exterior-wall heat insulation material of construction manufacture technology field.
Background technology
Thermal insulation mortar is take various light materials as aggregate, is equipped with gelating material, admixes some property-modifying additives, mixes and a kind of premixing dry-mix of making through manufacturing enterprise.Be mainly used in building exterior wall heat preserving, have the advantages such as easy construction, good endurance.
At present on the market thermal insulation mortar mainly is take cement as main gelling material, and from the angle of power consumption from sending out, cement per kilogram production energy consumption is at 700～1200 kilocalories, and can discharge a large amount of greenhouse gases CO
2, contaminate environment.Gypsum then is a kind of green material, and only 220～350 kilocalories of the every public production energy consumptions of gypsum are about 1/4 of cement energy consumption, and discharging is the water of environmental sound.
In addition, with the thermal insulation mortar of gypsum as gelling material, because gypsum exists not water-fast shortcoming, cause existing gypsum base thermal insulation mortar coefficient of softening relatively poor on the market, use at moist position is restricted, thereby requires very strict to waterproof construction in use.
Phosphogypsum is the solid slag that produces in phosphoric acid production, 5～6 tons of 1 ton of phosphoric acid deslagginves of every product.At present, most phosphogypsums are taken as waste and abandon.Pile up like a mountain for the phosphogypsum slag of discharging, and the problem of environmental pollution that brings is on the rise.And can not effectively utilize phosphogypsum as raw material in the existing thermal insulation mortar, therefore, produce thermal insulation mortar technology or not ideal enough with cement as main gelling material from the angle of energy-saving and emission-reduction.
Summary of the invention
The objective of the invention is: provide a kind of make energy consumption low, and can effectively utilize the preparation method of the higher gypsum base thermal insulation mortar of phosphogypsum and phosphorus slag and coefficient of softening, to overcome the deficiencies in the prior art.
The present invention is achieved in that the preparation method of a kind of gypsum base thermal insulation mortar of the present invention is; get by weight 5～10 parts of 10～15 parts of 40～50 parts of phosphogypsums, Yellow phosphorus furnace ground-slags, cement as gelling material, as 1～2 part of 30～35 parts of glass beads, the admixture of aglite as raw material, then each raw material is mixed and stir after can make gypsum base thermal insulation mortar take residue phosphogypsum and phosphorus slag as gelling material.
Above-mentioned phosphogypsum is the solid slag that produces in the phosphoric acid production.
Above-mentioned phosphorus slag is the solid slag that produces in the phosphorus production, and the powder body material that obtains behind ball milling.
The intensity of above-mentioned cement is the ordinary Portland cement more than or equal to 42.5.
The tap density of above-mentioned glass bead is 120～130kg/m
3
Above-mentioned admixture is the admixture with slow setting diminishing function.
When above-mentioned each raw material is mixed and stirs, adopt dry-mixed mortar production device to carry out mix and blend.
Owing to adopted technique scheme, the present invention to take full advantage of the characteristics that phosphogypsum is produced energy-conserving profit waste and environmentally safe, carried out the preparation of gypsum base thermal insulation mortar.Studies show that only 220～350 kilocalories of the every public production energy consumptions of phosphogypsum are about 1/4 of cement energy consumption, and without greenhouse gas emission, be a kind of green material.In addition, because the present invention utilizes phosphorus slag, cement etc. that phosphogypsum is carried out modification, improved the not water-fast shortcoming of phosphogypsum, make it can replace traditional cement as the lagging material gelling material, after tested, the coefficient of softening of gypsum base thermal insulation mortar of the present invention has improved 20%～30% than gypsum base thermal insulation mortar coefficient of softening of the prior art, and its water resistance is much higher than existing gypsum base thermal insulation mortar.Simultaneously, cheap because phosphogypsum of the present invention and phosphorus slag are industrial solid castoffs, can effectively reduce the production cost of thermal insulation mortar.The present invention prepares thermal insulation mortar with industrial solid castoff phosphogypsum and phosphorus slag as gelling material, and satisfied under the prerequisite of thermal insulation mortar requirement decrease in performance production energy consumption and cost reduced environmental pollution.The present invention utilizes phosphorus slag, cement etc. that phosphogypsum is carried out modification, has improved the not water-fast shortcoming of phosphogypsum, makes it can replace traditional cement to produce thermal insulation mortar as gelling material, has the advantage of environmental protection, excellent thermal insulation performance and easy construction.After tested, the gypsum base thermal insulation mortar thermal conductivity that the present invention makes is 0.068～0.072w/ (mk), and ultimate compression strength is 0.6～0.8MPa, and unit weight is 340～380kg/ m
3Therefore, the present invention compared with prior art, the present invention not only has low, the cheap advantage of energy consumption, can utilize effectively that phosphogypsum and phosphorus slag and product coefficient of softening are higher, the measured advantage of matter but also have; Adopt the present invention not only to meet the policy of energy-saving and emission-reduction, and can also effectively utilize the industrial solid castoffs such as phosphogypsum and phosphorus slag, reduce the discharging of waste residue and protect farmland.
