Abstract
The invention discloses a kind of preparation method of gypsum base thermal insulation mortar; be taken as by weight into the phosphogypsum 40 ~ 50 parts of gelling material, Yellow phosphorus furnace ground-slag 10 ~ 15 parts, cement 5 ~ 10 parts, as the glass bead 30 ~ 35 parts of aglite, admixture 1 ~ 2 part as raw material, then each raw material is mixed and the gypsum base thermal insulation mortar that can to obtain with residue phosphogypsum and phosphorus slag after stirring be gelling material.The present invention not only has low, the cheap advantage of energy consumption, but also has and effectively can utilize phosphogypsum and phosphorus slag and product coefficient of softening is higher, good quality; Adopt the present invention not only to meet the policy of energy-saving and emission-reduction, and can also effectively utilize the industrial solid castoff such as phosphogypsum and phosphorus slag, the discharge reducing waste residue is protected farmland.
Description
Technical field
The present invention relates to a kind of preparation method of gypsum base thermal insulation mortar, particularly a kind of gypsum base thermal insulation mortar preparation method that is major gelled material with residue phosphogypsum and phosphorus slag, belongs to exterior-wall heat insulation material of construction manufacture technology field.
Background technology
Thermal insulation mortar be with various light material for aggregate, be equipped with gelating material, admix some property-modifying additives, be uniformly mixed through manufacturing enterprise and a kind of premixing dry-mix made.Be mainly used in building exterior wall heat preserving, there is the advantage such as easy construction, good endurance.
Current thermal insulation mortar is on the market mainly major gelled material with cement, and from the angle consumed energy from sending out, cement per kilogram production energy consumption at 700 ~ 1200 kilocalories, and can discharge a large amount of greenhouse gases CO
2, contaminate environment.Gypsum is then a kind of green material, and the every public production energy consumption of gypsum only 220 ~ 350 kilocalories, is about 1/4 of cement energy consumption, and discharge is the water of environmental sound.
In addition, on the market using gypsum as the thermal insulation mortar of gelling material, because gypsum also exists not water-fast shortcoming, cause existing gypsum base thermal insulation mortar coefficient of softening poor, be restricted in the use at moist position, thus require very strict to waterproof construction in use.
Phosphogypsum is the solid slag produced in phosphoric acid production, often produces 1 ton of phosphoric acid deslagging 5 ~ 6 tons.At present, most phosphogypsum is taken as waste and abandons.Pile up like a mountain for the phosphogypsum slag of discharging, and the problem of environmental pollution brought is on the rise.And in existing thermal insulation mortar, can not effectively utilize phosphogypsum as raw material, therefore, produce thermal insulation mortar technology or not ideal enough from the angle of energy-saving and emission-reduction using cement as major gelled material.
Summary of the invention
The object of the invention is: provide a kind of energy consumption that makes low and effectively can utilize phosphogypsum and phosphorus slag and the preparation method of the higher gypsum base thermal insulation mortar of 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; be taken as by weight into the phosphogypsum 40 ~ 50 parts of gelling material, Yellow phosphorus furnace ground-slag 10 ~ 15 parts, cement 5 ~ 10 parts, as the glass bead 30 ~ 35 parts of aglite, admixture 1 ~ 2 part as raw material, then each raw material is mixed and the gypsum base thermal insulation mortar that can to obtain with residue phosphogypsum and phosphorus slag after stirring be gelling material.
Above-mentioned phosphogypsum is the solid slag produced in phosphoric acid production.
Above-mentioned phosphorus slag is the solid slag produced in phosphorus production, and the powder body material obtained after ball milling.
The intensity of above-mentioned cement be more than or equal to 42.5 ordinary Portland cement.
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 stirred, dry-mixed mortar production device is adopted to carry out mix and blend.
Owing to have employed technique scheme, the present invention takes full advantage of phosphogypsum and produces energy-conserving profit waste and the feature of environmentally safe, carries out the preparation of gypsum base thermal insulation mortar.Research shows, the every public production energy consumption of phosphogypsum only 220 ~ 350 kilocalories, is about 1/4 of cement energy consumption, and without greenhouse gas emission, is a kind of green material.In addition, because the present invention utilizes phosphorus slag, cement etc. to carry out modification to phosphogypsum, improve the shortcoming that phosphogypsum is not water-fast, make it that traditional cement can be replaced as lagging material gelling material, after tested, the coefficient of softening of gypsum base thermal insulation mortar of the present invention improves 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.Meanwhile, because phosphogypsum of the present invention and phosphorus slag are industrial solid castoffs, cheap, effectively can reduce the production cost of thermal insulation mortar.Industrial solid castoff phosphogypsum and phosphorus slag are prepared thermal insulation mortar as gelling material by the present invention, considerably reduce production energy consumption and cost, decrease environmental pollution in performance under meeting the prerequisite of thermal insulation mortar requirement.The present invention utilizes phosphorus slag, cement etc. to carry out modification to phosphogypsum, improves the shortcoming that phosphogypsum is not water-fast, makes it that traditional cement can be replaced 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
3.Therefore, compared with prior art, the present invention not only has low, the cheap advantage of energy consumption in the present invention, but also has and effectively can utilize phosphogypsum and phosphorus slag and product coefficient of softening is higher, the measured advantage of matter; Adopt the present invention not only to meet the policy of energy-saving and emission-reduction, and can also effectively utilize the industrial solid castoff such as phosphogypsum and phosphorus slag, the discharge reducing waste residue is protected farmland.
