Description
Technical field
The invention belongs to facing mortar technical field, and in particular to a kind of facing mortar of low contract with dry rate.
Background technology
With economic development, people require more and more higher and variation, traditional emulsion paint for architecture inside and outside decoration
People's demand can not be fully met with ceramic tile, facing mortar is because its color change range is big, molding surface abundant, weather-proof
Property good more and more welcomed by the people, facing mortar is made up of inorganic coagulation material, filler, additive and aggregate, uses
In building wall material and the material of ceiling decoration.The exterior wall of Most current building all does external thermal insulation, and facing mortar is with showing
Finish coat prepared by the organic materials such as some coating is compared, and facing mortar has more preferable matching and compatible with outer heat preservation system
Property.In addition, facing mortar is compared with tile decorative surface, facing mortar thickness degree is only 1-3mm, and light weight is adornd as skyscraper
During surface layer, the problems such as will not be because of negative blast there is brick phenomenon, it is to avoid the potential safety hazard of tile decorative surface, but existing facing
Mortar contract with dry rate problem still more substantially, it is dry-shrinkage deformed but be cause mortar ftracture one of the main reasons.
The content of the invention
The purpose of the present invention is that there is provided a kind of facing mortar of low contract with dry rate the problem of being directed to existing.
The present invention is achieved by the following technical solutions：
A kind of facing mortar of low contract with dry rate, is made up of following component by weight：Aluminate cement 45-60, silicate cement
Mud 9-12, gypsum 20-30, quartz sand 300-330, acrylic emulsion 3-8, hydroxymethyl cellulose 0.8-1.2, modified basalt are fine
Tie up 5.5-5.8, active attapulgite 3.6-4.5, pigment 1.2-1.6, defoamer 0.5-0.8, water 30-60；
The preparation method of the treated basalt fiber is：
（1）Granularity is scattered in deionized water for 70nm nano-bentonite particle, deionized water pH is adjusted to 5.5-
5.8, the KH550 of nano-bentonite quality 10% is then added, 88 DEG C are adjusted the temperature to, it is small with the stirring 2.5 of 2500r/min rotating speeds
When, separation of solid and liquid is then carried out under high speed centrifugation, then washed, dry, it is stand-by；；
（2）After 200 times of deionized water of nano-bentonite particle by above-mentioned processing and its quality is uniformly mixed, received
Rice bentonite solution, 1 is pressed by the nano-bentonite aqueous solution:2 mass ratios are equal for 2.2% acrylic acid solution with mass fraction
It is even admixed together, 78 DEG C are adjusted the temperature to, after being stirred 2 hours with 2000r/min rotating speeds, then nano-bentonite quality is added
15% lauroylamidopropyl betaine, after stirring, obtains modified solution；
（3）Basalt fibre precursor is made in basaltic broken stone, basalt fibre precursor and above-mentioned modified solution are pressed 1:10 matter
Measure after ratio uniform mixing, be heated to 80 DEG C, after being incubated 2 hours, it is at 25kHz ultrasonic wave for 300W, frequency to use power
5min is managed, insulation 2 hours is then proceeded to, then filters, dries, produces.
Further, the aluminate cement and portland cement mass ratio are 5:1.
Further, the active attapulgite preparation method is：Attapulgite is calcined into 40min at 450 DEG C, then
100 DEG C are cooled to, is added in high-speed mixer, then is added under the diethyl phosphate of its quality 1.2%, then 2000r/min rotating speeds
Mixed processing 30min is carried out, then takes out, is cleaned using deionized water, drying to constant weight, you can.
Further, the pigment is azo pigment.
Further, the defoamer uses dimethyl silicone polymer.
The present invention has advantages below compared with prior art：Facing mortar cost prepared by the present invention is relatively low, with weather-proof
Property good, impervious, waterproof, mould proof, energy-conserving and environment-protective, dry powder easy to maintain, convenient transportation, long shelf-life, the low feature of shrinkage factor, be adapted to
Applied in the building inside and outside wall under various environmental weather conditions, by using 5:Aluminate cement, the silicate, Neng Gouyi of 1 proportioning
Determine to reduce the shrinkage factor of facing mortar in degree, by adding the synergy of active attapulgite, this hair can be significantly reduced
The shrinkage factor of bright facing mortar, facing mortar shrinkage factor prepared by the present invention is low, can reduce when mortar condenses in different pacts
Under pencil state because of caused by contraction tension, while by being modified to basalt fibre, facing can greatly be strengthened
The tensile strength of mortar so that the tensile strength of facing mortar of the present invention is noticeably greater than because of the tension that contraction is got up, so as to keep away
Exempt from the generation in mortar crackle or crack, it is ensured that the durability performance of mortar.
