Description
Technical field
The present invention relates to building materials mortar technical field, especially a kind of novel light gypsum mortar material.
Background technology
Environmental pollution and energy consumption are the great difficult problems that the world today faces.Environment and the energy have become the economic hair of restriction
An important factor for exhibition.It is also that scientists from all over the world are badly in need of the key subjects solved.
In order to protect human environment, the content of sulfur dioxide in air is reduced, firepower electrical plant takes flue gas desulfurization technique to arrange
It applies, produces a large amount of desulfurized gesso of flue gas.Its main component is calcium sulphate dihydrate, and content is generally more than 85%.China
Every year there are about 8,000,000 tons of desulfurized gesso of flue gas outputs, quantum of output is very huge.
Desulfurated plaster product deep process technology is immature at present, technical standard shortage, high processing costs, energy consumption are big etc. because
Element causes desulfurated plaster not to be utilized effectively.A large amount of desulfurated plaster is stacked, is filled, not only pollution of ecological environment, also
Invisible increase production cost.Therefore solid waste desulfurated plaster comprehensive utilization firepower electrical plant generated is a urgent subject.
The summary situation present invention illustrates a kind of novel light gypsum mortar material.To ecological environmental protection, economic effect
Benefit increases, reduces production cost with positive effect.
Invention content
In view of the above-mentioned problems, it is an object of the present invention to provide a kind of Recompounded multielement desulfurated plaster light mortar and its preparation sides
Method.Prepared mortar is by solid waste desulfurated plaster, dry powder and light material glass bead is compound is prepared, not only intensity
Good, light-weight and simple for process, cost is also than relatively low.
In order to achieve the above object, the present invention is achieved by the following technical programs：
A kind of Recompounded multielement desulfurated plaster light mortar, is prepared from the following raw materials in parts by weight：Desulfurated plaster 44-48
Part, 4-11 parts of glass bead, 44-48 parts of dry powder, 0.2-0.5 parts of retarder, 0.20-0.30 parts of cellulose ether and water 58-70
Part.
Preferably, the gypsum selects the desulfurated plaster that purity is more than 85%.
Preferably, the unit weight of the glass bead is 180g/L.
Preferably, the grain size of the dry powder is 1250 mesh.
Preferably, the retarder selects SC high-efficient retarders.
Preferably, the cellulose ether is methyl cellulose ether, in hydroxyethyl ether cellulose, hydroxypropylcelluloether ether
It is a kind of.
A kind of preparation method of Recompounded multielement desulfurated plaster light mortar, includes the following steps：
A, by above-mentioned each raw material of components by weight percent precise：
B, each raw material load weighted in step a is crushed, then carries out being thoroughly mixed uniformly, obtain mixture
Material；
C, it is accurate to weigh institute's water requirement, and by the mixed material of gained in the water weighed addition step b, be then turned on stirring
Device is mixed, 2min is first mixed slowly, then stands 15s；Again quickly stirring 2min to get to product.
Beneficial effects of the present invention：
1st, solid waste desulfurated plaster comprehensive utilization problem is effectively solved.Realize environmental benefit and economic benefit win-win.
2nd, product strength is preferable, light-weight.
3rd, preparation process is simple, at low cost.
4th, it has good workability, wall works well on mortar.
Specific embodiment
Purpose, technical scheme and advantage to make the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present invention,
Technical solution in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is the present invention one
Divide embodiment, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making
All other embodiments obtained under the premise of creative work, shall fall within the protection scope of the present invention.
Embodiment one：
Following raw material are weighed by weight：
44 parts of desulfurated plaster, 11 parts of glass bead, 44 parts of dry powder, 0.3 part of high-efficient retarder, 0.25 part of cellulose ether and
70 parts of water, is mixed evenly, and novel light gypsum mortar material is made.
Embodiment two：
Following raw material are weighed by weight：
45 parts of desulfurated plaster, 9 parts of glass bead, 45 parts of dry powder, 0.4 part of high-efficient retarder, 0.30 part of cellulose ether, water
It 68 parts, is mixed evenly, novel light gypsum mortar material is made.
Embodiment three：
Following raw material are weighed by weight：
46 parts of desulfurated plaster, 7 parts of glass bead, 46 parts of dry powder, 0.3 part of high-efficient retarder, 0.25 part of cellulose ether and
70 parts of water, is mixed evenly, and novel light gypsum mortar material is made.
Example IV：
Following raw material are weighed by weight：
48 parts of desulfurated plaster, 4 parts of glass bead, 48 parts of dry powder, 0.4 part of high-efficient retarder, 0.30 part of cellulose ether and
65 parts of water, is mixed evenly, and novel light gypsum mortar material is made.
Embodiment five：
Material of the present invention and common brushing gypsum plastering mortar material are compared.
16 parts of 30 parts of the natural gypsum, 70 parts of sand, 0.3 part of high-efficient retarder, 0.25 part of cellulose ether and water are mixed equal
It is even, common brushing gypsum plastering mortar material is made.
Novel light gypsum mortar material and common brushing gypsum plastering mortar material are subjected to performance comparison：
1st, Fig. 1 is the changing bulk density figure of different embodiments；
As can be seen from Figure 1 example IV is maximum for the unit weight of common brushing gypsum plastering mortar, has reached 1533kg/
m3.The unit weight of one novel light gypsum mortar of embodiment is 670kg/m3.The two differs about 2.3 times.Under equal conditions, novel light
