Description
Technical field
The present invention relates to building additive technical fields, particularly relate to a kind of mortar reinforcing agent and preparation method thereof.
Background technology
Plastering for building, painting, masonry mortar are mixed by cement, Sha Heshui at present.In mixed process, cement
Particle surface is hydrolyzed with water contact start and aquation, generates calcium silicate hydrate and calcium hydroxide, and these neoformations are gradually coagulated
Poly-, much larger than water to the infiltration power inside cement granules, these neoformations are condensed into condensate and are wrapped in cement cohesiveness
Around grain, retardance cement granules further hydrolysis and aquation, and through aquation be only the meagre part of cement particle surface,
Its internal formation is difficult to hydrolyzed and aquation " core ".Cause mobility and the workability of mortar poor in this way, in the construction process
In order to obtain suitable workability, water consumption is not only increased, but also lime paste, foaming agent, lime are mixed in mortar
The additives such as king or mortar king are to improve the mobility and workability of mortar.
However more or less there is certain defect in existing additive, such as：Lime paste is mixed in plastering, paints or build by laying bricks or stones
Snuff, cracking, hollowing and other issues are susceptible in mortar, after a period of time；And foaming agent, lime king, mortar king incorporation
Easy to produce bubble in mortar, there are crafters in mortar, reduce the intensity of mortar.Therefore, it is necessary to a kind of new technical solutions
To solve above-mentioned technical problem.
Invention content
In order to overcome the above problem, a kind of mortar reinforcing agent of present invention proposition and preparation method thereof.
The technical proposal of the invention is realized in this way：A kind of mortar reinforcing agent, includes the raw material of following parts by weight：
2-10 parts of naphthalene water reducer, 0-50 parts of polycarboxylate water-reducer, 10-20 parts of hydroxypropyl methyl cellulose, calcium silicate powder
10-40 parts, 10-20 parts of Hua Qiansu, 5-10 parts of calcium chloride, 0-50 parts of starch ether, 1-10 parts of polyacrylamide, pva powder
1-10 parts, 1-5 parts of silylation hydrophober, 1-10 parts of cement intensifier, 1-5 parts of mortar plasticizer, 0-50 parts of calcium formate.
Preferably, naphthalene water reducer is sodium metnylene bis-naphthalene sulfonate polymer.
Preferably, the cement intensifier include the diethylene glycol (DEG) of 10 parts by weight, the malt sugar of 18 parts by weight, 3 parts by weight three
The anhydrous sodium sulfite of ethanol amine, 2 parts by weight, 5 parts of water.
Preferably, the mortar plasticizer is by the lauryl sodium sulfate of 45 parts by weight, the dodecyl sulphur of 35 parts by weight
The flyash composition of sour sodium, the fine sand of 5 parts by weight, the anhydrous sodium sulphate of 100 parts by weight, 8 parts by weight.
Preferably, the starch ether is carboxymethyl starch ether.
The present invention proposes a kind of preparation method of mortar reinforcing agent again, including step：
Naphthalene water reducer, polycarboxylate water-reducer, hydroxypropyl methyl cellulose, calcium silicate powder, chlorination are weighed successively by formula
Calcium, starch ether, polyacrylamide, pva powder, silylation hydrophober, cement intensifier, mortar plasticizer, calcium formate are put
Into mixing machine, at ambient temperature uniform stirring 30min to get.
Beneficial effects of the present invention：
1) present invention had not only used naphthalene water reducer but also had used polycarboxylate water-reducer, but stressed to subtract using polycarboxylic acids
Aqua, polycarboxylate water-reducer guarantor's plasticity is strong, can efficiently control Slump Time losing of Large, and not to concrete hardening time effects
Greatly；Humidification is big, and has shrinkage resistance, can more effectively improve impermeability, the frost resistance of concrete, thus than other
High efficiency water reducing agent can larger improve the durability of concrete；
2) starch ether of the invention, i.e. etherification starch are that the hydroxyl in starch molecule is generated with reactivity substance reaction
Starch substituent group ether, since the etherification of starch improves stability of viscidity, and ehter bond is not easy to send out under strongly alkaline conditions
Unboiled water solution, therefore, etherification starch have fast thickening in mortar, the sag resistance ability for improving material, extend the operating time, carry
The functions such as high-moisture-retention, and there is good compatibility with other materials；
3) include mortar plasticizer in the present invention, mortar water consumption is decreased obviously after adding plasticizer, when consistency is close,
Water consumption can reduce 10% or more, and even more, initial set and final setting time slightly delay, little to construction infection；(2) plasticising is mixed
To the influence after mortar laminated after agent, the coursing degree of mortar for mixing plasticizer meets the regulation of mortar technology requirement (being not more than 3cm),
Significantly lower than the delamination degree of benchmark mortar, water retentivity of mortar can be improved after mixing plasticizer, and the workability of mortar is excellent；
(3) variation of mortar volume.The mortar after plasticizer is mixed, gas effect is generated by stirring, mortar air content is made to increase in right amount,
Workability improves, and the apparent density of mortar reduces, and volume increases when benchmark mortar identical quality ratio, generally speaking mixes plasticising
Mortar after agent, the workability of mortar, viscosity is good, easy to operate；
4) its dosage of mortar reinforcing agent of the present invention is only the 1% to 10% of mortar, can reduce mortar to greatest extent
Water consumption, close structure after mortar solidification, quality is hard and flexible, and than good, it is difficult qualification to solve backfin ratio in detection for backfin
The problem of, compression strength can be improved 50%, without blister, impermeable；And preparation method is simple；
5) cement mortar reinforcing agent of the present invention can improve the physical and mechanical property of mortar, increase water-retaining property and the stretching of mortar
Adhesion strength, since water retention is compared with ordinary mortar height, mortar moisture content is not easy to be absorbed by air entrained concrete, promotes air entrained concrete circle
Cement abundant aquation in face improves the adhesion strength of mortar and air entrained concrete, to effectively solve air-entrained concrete building block plastering
The problems such as easy cracking, hollowing of mortar even falls off.
