Description
Technical field
The invention belongs to mortar preparation technical field, specially a kind of water-resistant type desulfurization plastering mortar.
Background technique
Mortar be building on lay bricks use cohere substance, by a certain proportion of sand and cementing material (cement, lime
Cream, clay etc.) it adds water into, it is also mortar, also makees mortar, there are commonly cement mortar, mixed mortars (or to be Behavior of Hardened Cement Paste for mortar
Lime and brick), lime mortar and clay mortar.It is broadly divided by its type: masonry mortar, decorative mortar, diagenesis mortar, Waterproof sand
Slurry, corrosion-resistant mortar and thermal insulation mortar.
Desulfurized gypsum is also known as flue gas desulfurization gypsum, sulphur gypsum or FGD stone, and desulfurized gypsum is the byproduct of FGD process, FGD
Process is industrial by-product obtained in a technology using the sulfur dioxide in lime-coal-fired or oily flue gas of lime stone recycling
Gypsum, referred to as desulfurized gypsum are widely used in the industries such as building materials.The meaning of its processing and utilization is very great, it not only effectively promotees
Into the further development of national environmental protection circular economy, and it is also greatly reduced the yield of ore cream, protects resource, because
This is it is proposed that a kind of water-resistant type desulfurization plastering mortar.
Summary of the invention
It is an object of the invention to: it is serious in order to solve the existing industrially desulfurized big environmental pollution of gypsum discharge capacity, without very
The problem of being reused well provides a kind of water-resistant type desulfurization plastering mortar.
The technical solution adopted by the invention is as follows:
A kind of water-resistant type desulfurization plastering mortar, including aggregate, cementing material and spike reconcile, and the aggregate includes: sand
And clinker；
The cementing material includes: cement, boron mud and desulfurized gypsum；
The spike includes: organic fiber, retarder, water-retaining agent and hydrophober；
Each Material Percentage are as follows: sand 15%, clinker 10%, cement 33%, boron mud 10%, desulfurized gypsum 20%, organic fiber
8%, retarder 0.5%, water-retaining agent 0.5%, hydrophober 3%.
Wherein, the organic fiber includes hemp cut.
Wherein, the organic fiber further includes polypropene staple, weight percent are as follows: hemp cut 45%, polypropene staple
55%。
Wherein, the retarder is sugar calcium, gluconate, citric acid, tartaric acid, zinc salt, phosphate and lignosulfonic acid
Any one or a few in salt.
Wherein, the retarder is ligninsulfonate.
Wherein, the water-retaining agent is hydroxypropyl methyl cellulose water-retaining agent.
Wherein, the hydrophober is polysiloxanes powder hydrophober.
Wherein, the hydrophober uses DOW CORNING SHP-50 model hydrophober.
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:
1, in the present invention, by the way that desulfurized gypsum and a variety of materials are carried out mixing match, plastering mortar is made, realizes desulfurization stone
The recycling and reusing of cream not only alleviates China's pollution of a large amount of outputs and the desulfurized gypsum of accumulation to natural remission every year, together
When desulfurized gypsum reserves it is big, at low cost, the manufactured more existing high-purity water cement mortar of plastering mortar, cost is under control,
With good market prospects.
2, in the present invention, by the way that boron mud and hydroxypropyl methyl cellulose water-retaining agent is added, so that the water-retaining property of mortar obtains
It is significantly promoted, when being plastered, mortar is easier to be attached on metope, while also avoiding being easy the dry feelings for leading to cracking
Condition occurs.
3, in the present invention, by the way that hemp cut and polypropene staple is added, and hemp cut is a kind of fibrous material, is the original of the rope made of hemp
Material carries out chopping and upsets into floccule, after mortar is added, so that can be very good to be connected to one in each region after mortar plastering
It rises, to promote the integral strength after mortar plastering.
4, in the present invention, by the way that clinker is added, the structural strength after promoting mortar plastering, while hydrophober is used, it is promoted
Water resistance after mortar plastering avoids since the hygroscopicity of desulfurized gypsum leads to internal expansion of plastering, and then leads to structure
Loosely, or even there are the case where falling off, more traditional gypsum plastering mortar, intensity is improved significantly.
