Abstract

The invention discloses a plastic stabilizer for wet-mixed mortar. The plastic stabilizer comprises the following components in parts by weight: 0.1-5 parts of a water retention agent, 0.1-5 parts of an air entraining agent, 0.1-1 part of a defoaming agent, 0.01-1 part of water soluble polysaccharide, 1-10 parts of a special effect retarder, 1-10 parts of a water reducing agent and 68-98 parts of water. The plastic stabilizer for the wet-mixed mortar, provided by the invention, is liquid, is beneficial for automatic feeding and metering, and overcomes the defects that most mortar additives on the market are solid powder products and cannot realize automatic metering. Meanwhile, the water retention rate of the plastic stabilizer for the wet-mixed mortar, provided by the invention, can reach 98%, so that the setting time of the mortar can be deferred to 10-72 hours.

Description

A kind of wet mixing mortar plasticity stablizer
Technical field
The present invention relates to a kind of wet mixing mortar plasticity stablizer.
Background technology
2007, national six ministries and commissions dispatched a joint document, and forbid that urban mixes cement mortar at the construction field (site), premixing mortar is progressively applied since then.Premixing mortar can be divided into dry-mixed mortar and wet mixing mortar two kinds.The shortcoming of dry-mixed mortar is: in bulk shipment with when storing, and because the density difference of cement and sand is apart from comparatively large, air conveyingly easily causes cement and sand layering, lack of homogeneity; And packed dry-mixed mortar at the scene stirring can cause secondary pollution; In addition, dry-mixed mortar needs sand to dry rear use in process of production, and oven dry cost is higher, is unfavorable for energy-conserving and environment-protective.All material is stirred at stirring station and delivers to building site by wet mixing mortar in advance, is positioned in storage tanks, with get with.Wet mixing mortar can use damp sand, decreases baking operation, and abridged edition lowers consumption, and is the major action of another energy-saving and emission-reduction after ready mixed concrete.
But after ordinary mortar mixing, generally can lose plasticity at 4 hours later, cannot use, and wet mixing mortar is in stirring station mixing, be transported to scene with transport mixer, single traffic capacity is large, generally just can need be finished even for more time through more than 6 hours, this just requires that mortar should keep plasticity-for a long time.
Summary of the invention
The technical problem to be solved in the present invention is the defect overcoming prior art, provides a kind of wet mixing mortar plasticity stablizer of liquid state.
Object of the present invention carrys out specific implementation by the following technical programs:
A kind of wet mixing mortar plasticity stablizer, each component by weight:
Water-holding agent: 0.1 ~ 5 part;
Air entrapment agent: 0.1 ~ 5 part;
Defoamer: 0.1 ~ 1 part;
Water-soluble saccharan: 0.01 ~ 1 part;
Special efficacy retardant: 1 ~ 10 part;
Water reducer: 1 ~ 10 part;
Water: 68 ~ 98 parts.
Preferably, above-mentioned wet mixing mortar plasticity stablizer, each component by weight: water-holding agent 1 part, air entrapment agent 0.5 part, defoamer 0.2 part, water-soluble polysaccharide 0.1 part, special efficacy retardant 4 parts, water reducer 5 parts, 89.2 parts, water.
Water-holding agent Main Function is that the moisture in locking wet mixing mortar does not run off, and ensures the water retention property of mortar; Air entrapment agent Main Function increases mortar air content, makes the more soft thickness of mortar; Defoamer Main Function eliminates deleterious bubbles in mortar; Water-soluble saccharan Main Function increases mortar viscosity, keeps water retentivity of mortar energy; Special efficacy retardant Main Function delays mortar coagulation time, keeps mortar plasticity; Water reducer Main Function reduces mortar water consumption, improves mortar strength; Water Main Function dissolves other component, makes liquid product.
Preferably, described water-holding agent is one or more of ether of cellulose, acrylamide or polyacrylamide.
Preferably, described air entrapment agent is one or more in triterpenoid saponin, sodium lauryl sulphate or colophonium pyrolytic polymer.
Preferably, described defoamer is silicone antifoam agent or polyether antifoam agent.
Preferably, described special efficacy retardant is one or more in Sunmorl N 60S, sucrose, tartrate, pyrophosphorous acid sodium or sodium phosphate.With Sunmorl N 60S and sucrose by 1:1 mass ratio be mixed into optimal selection.
Preferably, described water reducer is the one in polycarboxylate water-reducer, naphthalene water reducer, lignin sulfonate water reducer.Optimal selection is naphthalene water reducer or lignin sulfonate water reducer.
Feed composition is obtained plasticity stablizer of the present invention through abundant stirring and dissolving.During use, volume of the present invention is about 3% of mortar gross weight.
Beneficial effect of the present invention:
Wet mixing mortar plasticity stablizer provided by the invention is liquid, is conducive to automatic charging and metering, overcome grout additive on market mostly be solid powder product cannot the shortcoming of automatic gauge.Meanwhile, wet mixing mortar plasticity stablizer water retention of the present invention can reach 98%, can delay mortar coagulation time to 10 ~ 72 hour.This product is mainly used in wet mixing mortar, to the improvement major embodiment of wet mixing mortar performance in the following areas:
(1) the present invention has mortar coagulation time and obviously delays effect, and according to the consumption of slow setting component, adjustable mortar coagulation time is in 10 ~ 72 hours window.
(2) the state of the present invention to fresh mortar has clear improvement, the workability of non-admixture blank mortar of the present invention is poor, bleeding has appearred in mortar surface very soon, and admixture mortar of the present invention is soft, thickness, workability is fine, and after depositing for some time, bleeding is also little.
(3) the present invention can make the denseness loss of fresh mortar obviously reduce, the denseness loss in 2 hours of general blank mortar is more than 30%, and admixture mortar of the present invention denseness free of losses in 2 hours; Blank mortar 24 hours setting and harden, admixture mortar of the present invention 24 hours denseness rate of loss are 15%, still can keep plasticity, have application operability.Product of the present invention can stablize mortar plasticity well, makes mortar keep plasticity-in 36 hours, advantageously in the application of wet mixing mortar.
(4) the present invention can make fresh mortar water retention property increase substantially, and water retention can reach 98%.
(5) the present invention can make mortar strength increase.
