Description
Technical field
The present invention relates to a kind of mortar for building, more particularly to a kind of weather resistant polymer emulsion cement mortar and its preparation
Method.
Background technology
With the sustainable development of concrete technology and the continuous improvement of China's Technological Economy demand, concrete harbour,
It is widely applied in the modernization project construction such as dam, bridge, airport, municipal administration, highway and high-speed railway, however,
Because the Concrete Structure Design is unreasonable, construction existing defects, and environmental attack, the reason such as improper is safeguarded, China is repaiied early stage
Industry and the civil buildings built, which have, is greatly badly in need of reinforcing and maintenance, or even architectural engineering newly-built in recent years also occurs
Different degrees of damage.
It is contemplated that within suitable long-term from now on, China's building trade will complete from based on newly-built infrastructure to repairing
Mend and renovate the strategic change based on infrastructure.This strategic change, research and application for patching material provide
Wide space, even more brings stern challenge.
Existing patching material can be divided into inorganic, organic and organically-modified class, wherein inorganic repairing material by composition
There is the problems such as adhesion strength is low, shrinkage factor is big in material, and organic patching material is then poor with cement concrete substrate compatibility, and
And cost is too high.Organically-modified class patching material is mostly using redispersable latex powder, polyvinyl acetate emulsion, epoxy emulsion
It is modified Deng polymer, the shortcomings of cost is higher, shrinkage factor is big is present.
The content of the invention
In order to overcome drawbacks described above, a kind of technique of present invention offer is simple, cost is low, the polymer emulsion water of excellent performance
Cement mortar and preparation method thereof.
The technical solution adopted for the present invention to solve the technical problems is：A kind of weather resistant polymer emulsion cement mortar,
By mass percentage, it is made by following raw materials according：
The polymer emulsion is at least one of styrene-acrylic emulsion and styrene-butadiene emulsion；The styrene-acrylic emulsion is purchased from Bei Jingdong
Fang Yongyu high molecular products Co., Ltd.
The present invention is modified using at least one of styrene-acrylic emulsion and styrene-butadiene emulsion as polymer emulsion to mortar,
The polymer emulsion cement mortar of preparation has the characteristics of shrinkage factor is small, adhesion strength is high, pressure-proof and snap-resistent intensity is high.
It is preferred that the cement is at least one of 42.5 grades of portland cements and sulphate aluminium cement.
It is preferred that the quartz sand is the quartz sand of 20-140 mesh.
It is preferred that the water-loss reducer is hydroxypropyl methyl cellulose.
The defoamer can be at least one of liquid antifoam agent and solid defoaming agent；The solid defoaming agent is
P803；Liquid antifoam agent is at least one of NXZ and F111.
It is preferred that the defoamer is made up of solid defoaming agent and liquid antifoam agent, it is described as further preferred scheme
The content of solid defoaming agent is 0.05%~0.1% in weather resistant polymer emulsion cement mortar, the content of liquid antifoam agent
0.005%~0.05%, it can so improve the workability and compression strength of mortar.
It is preferred that the water reducer is at least one of polycarboxylate water-reducer and melamine water reducer.
(the cement of the quality of polymer emulsion × 0.48/ it is preferred that polymer cement ratio in the weather resistant polymer emulsion cement mortar
Quality) be 8-16%.It can so obtain that toughness is stronger, and shrinkage factor is lower, the higher mortar of adhesion strength.
The present invention also provides a kind of preparation method of weather resistant polymer emulsion cement mortar：By cement, quartz sand, water conservation
Agent, solid defoaming agent, water reducer put into mortar mixer successively, are well mixed, obtain premix powders；By polymer emulsion, liquid
Body defoamer, water put into mixer successively, are well mixed, and obtain premixing liquid material；It is slowly added to premix liquid material in premix powders,
Stir, obtain weather resistant polymer emulsion cement mortar.
Beneficial effects of the present invention are as follows：
1. the present invention prepares mortar using styrene-acrylic emulsion and styrene-butadiene emulsion, reduce the shrinkage factor of mortar, improve mortar
Adhesion strength, rupture strength.
2. defoamer of the present invention is made up of solid defoaming agent and liquid antifoam agent, the association of solid defoaming agent and liquid antifoam agent
Same-action makes prepared mortar have more preferable workability and compression strength.
3. polymer cement ratio is 8-16% in polymer emulsion cement mortar.It can so obtain that toughness is stronger, and shrinkage factor is lower,
The higher mortar of adhesion strength.
4. the preparation method of the weather resistant polymer emulsion cement mortar is simple, cost is low, and the mortar prepared can be
When use.
5. the present invention reduces engineering cost, reduce environmental pollution etc. has to improving construction quality and service life
Significance, available for building repairing work or directly apply to particular/special requirement architectural engineering (such as subway, reservoir, underground
Room etc.).
