Description
Technical field
The present invention relates to a kind of mortar for building, particularly relate to a kind of weather resistant polymer emulsion sand-cement slurry and preparation method thereof.
Background technology
Along with the sustainable development of concrete technology and improving constantly of China's Technological Economy demand, concrete is widely applied in the modernization project construction such as harbour, dam, bridge, airport, municipal administration, motorway and high-speed railway, but, because the Concrete Structure Design is unreasonable, construction existing defects, and the reason such as environmental attack, maintenance be improper, the industry that China builds in early days and covil construction have to be badly in need of reinforcing and keeping in repair greatly, and damage in various degree has also appearred in construction work newly-built even in recent years.
Can predict, from now on quite over a long time in, China's building trade is main to repair and renovation Infrastructure is main strategic change by completing by newly-built Infrastructure.This strategic change, the investigation and application for patching material provides wide space, brings stern challenge especially.
Existing patching material can be divided into mineral-type, organic and organically-modified class by composition, and wherein mineral-type patching material exists the problems such as cohesive strength is low, shrinking percentage is large, and organic patching material is then poor with cement concrete substrate compatibility, and cost is too high.Organically-modified class patching material uses the polymkeric substance such as redispersable latex powder, aqueous polyvinyl acetate emulsion, epoxy emulsion to carry out modification mostly, there is the shortcomings such as cost is higher, shrinking percentage is large.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides that a kind of technique is simple, cost is low, the polymer emulsion sand-cement slurry of excellent performance 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 sand-cement slurry, by mass percentage, is obtained by following raw materials according:
Described polymer emulsion is at least one in benzene emulsion and styrene-butadiene emulsion; Described benzene emulsion is purchased from Beijing Orient Yong Yu high molecular products company limited.
The present invention adopts at least one in benzene emulsion and styrene-butadiene emulsion to carry out modification as polymer emulsion to mortar, and the polymer emulsion sand-cement slurry of preparation has the advantages that shrinking percentage is little, cohesive strength is high, pressure-proof and snap-resistent intensity is high.
Preferred described cement is at least one in 42.5 grades of silicate cements and aluminosulfate cement.
Preferred described quartz sand is 20-140 object quartz sand.
Preferred described water-holding agent is Vltra tears.

Preferred described defoamer is made up of solid defoamer and liquid antifoam agent, as further preferred version, in described weather resistant polymer emulsion sand-cement slurry, the content of solid defoamer is 0.05% ~ 0.1%, the content 0.005% ~ 0.05% of liquid antifoam agent, can improve workability and the ultimate compression strength of mortar like this.
Preferred described water reducer is at least one in polycarboxylate water-reducer and melamine water reducer.
In preferred described weather resistant polymer emulsion sand-cement slurry, polymer cement ratio (quality of quality × 0.48/ cement of polymer emulsion) is 8-16%.Can obtain toughness so stronger, shrinking percentage is lower, the mortar that cohesive strength is higher.
The present invention also provides a kind of preparation method of weather resistant polymer emulsion sand-cement slurry: cement, quartz sand, water-holding agent, solid defoamer, water reducer are dropped into mortar mixer successively, mixes, obtain premix powders; Polymer emulsion, liquid antifoam agent, water are dropped into stirrer successively, mixes, obtain premix liquid material; In premix powders, slowly add premix liquid material, stir, obtain weather resistant polymer emulsion sand-cement slurry.
Beneficial effect of the present invention is as follows:
1. the present invention uses benzene emulsion and styrene-butadiene emulsion to prepare mortar, reduces the shrinking percentage of mortar, improves cohesive strength, the folding strength of mortar.
2. defoamer of the present invention is made up of solid defoamer and liquid antifoam agent, and the synergy of solid defoamer and liquid antifoam agent makes prepared mortar have better workability and ultimate compression strength.
3. in polymer emulsion sand-cement slurry, polymer cement ratio is 8-16%.Can obtain toughness so stronger, shrinking percentage is lower, the mortar that cohesive strength is higher.
4. the preparation method of this weather resistant polymer emulsion sand-cement slurry is simple, cost is low, and the mortar of preparation can use immediately.
5. the present invention is to raising construction quality and work-ing life, reduce engineering cost, reduce the aspects such as environmental pollution significant, can be used for the repairing work of buildings or directly apply to particular requirement construction work (as subway, reservoir, vault etc.).
