Abstract
The present invention provides a kind of wet mixing mortar consistency modifiers and preparation method and application, belongs to grout additive technical field, solves the technical problem that current wet mixing mortar caking ability is bad, workability is poor.Wet mixing mortar consistency modifiers provided by the invention, are made up of the component of following parts by weight：90~120 parts of 0.05~1.5 part of aliphatic APEO sodium sulphate, 3~5 parts of thickener and water.The preparation method of the wet mixing mortar consistency modifiers is to mix the aliphatic APEO sodium sulphate, thickener and water of above-mentioned parts by weight, is uniformly mixing to obtain.Application of the wet mixing mortar consistency modifiers in wet mixing mortar is prepared is to be added to above-mentioned wet mixing mortar consistency modifiers in wet mixing mortar for the 1.0%~1.8% of binder materials gross mass according to addition, is stirred.Wet mixing mortar consistency modifiers provided by the invention enhance water-retaining property, caking ability and the workability of wet mixing mortar, improve the performance of wet mixing mortar.
Description
Technical field
The present invention relates to a kind of wet mixing mortar conditioning agent, more particularly to a kind of wet mixing mortar consistency modifiers and its preparation side
Method and application, belong to grout additive technical field.
Background technology
Grout additive, for build by laying bricks or stones with motar.After adding consistency of mortar conditioning agent, mortar is bulk, soft, viscous
Tie the probability that power is strong, reduction landing is grey.Because full degree of mortar at bed joint is high, contraction is small, and metope is easily cracked, empty after overcoming hardening
The common fault such as rouse, come off, bubbling, the workability endurance issues for greatly solving mortar.
At present grout additive mainly have lime king, smear happy, rock sand is smart, mortar king, mortar treasured etc., using pulvis as
Main, most mortars are uneven there is stirring at the construction field (site), and caking ability is bad, or shrink the problem of big.On formula, mortar
Additive more using cellulose ether as the component for improving cohesiveness, in use, due to mix inequality or with using
Cement type is different and caused workability is not suitable with, and mortar and contact surface is produced bonding uneven, and threshing, by force occurs
Spend decline, hollowing, the image of cracking.
The content of the invention
It is an object of the invention to solve the technical problem that wet mixing mortar caking ability is bad, workability is poor, there is provided a kind of
Wet mixing mortar consistency modifiers and preparation method and application.
To achieve these goals, the invention provides following technical scheme：
A kind of wet mixing mortar consistency modifiers, are made up of the component of following parts by weight：
0.5~1.5 part of aliphatic APEO sodium sulphate；
3~5 parts of thickener；
90~120 parts of water.
The thickener is maltose essence, sodium alginate or polyacrylamide recklessly.
Preferably, above-mentioned wet mixing mortar consistency modifiers, are made up of the component of following parts by weight：
1 part of aliphatic APEO sodium sulphate；
4 parts of thickener；
95 parts of water.
The preparation method of above-mentioned wet mixing mortar consistency modifiers, it is by the aliphatic APEO sulfuric acid of above-mentioned parts by weight
Sodium, thickener and water mixing, stir, obtain wet mixing mortar consistency modifiers.
Application of the above-mentioned wet mixing mortar consistency modifiers in wet mixing mortar is prepared, by above-mentioned wet mixing mortar consistency modifiers
It is added in wet mixing mortar, stirs；The addition of the wet mixing mortar consistency modifiers is binder materials gross mass
1.0%~1.8%；The binder materials refers to the mixture of cement, flyash and miberal powder.
Preferably, the addition of the wet mixing mortar consistency modifiers is the 1.3% of binder materials gross mass.
Compared with prior art, the technique effect that obtains of the present invention is：
The present invention forms association using the interaction of oleophylic segment Van der Waals power between pfpe molecule, in certain outer masterpiece
Separated with lower association, so that viscosity declines, be advantageous to levelling and then improve workability early stage.After shearing force is eliminated, it
It can recover rapidly to associate again, system viscosity rises the absorption improved between later stage cement granules and wall, ceramic tile interfacial molecular
Power, strengthen the bonding at cement and interface.And liquid dosage is used, there is good peptizaiton to cement particle surface, reduce
Water consumption when mortar mixes and stirs, improve the workability of cement mortar.Tradition is substituted using aliphatic APEO sodium sulphate
Cellulose ethers, cost is lower, effect is more preferable.In addition, liquid mortar consistency modifiers are easier control accuracy in production,
Corresponding adjustment is easily made according to environmental factor, the workability index needed according to the performance indications of cement, unit in charge of construction
Allocated at any time, the transition and upgrade for being more suitable for concrete mixing plant uses.
