Abstract
The present invention relates to a kind of mucosal pattern curing compound and preparation method thereof, its raw material group becomes the mucosal pattern curing compound by mass percentage：Anhydrous magnesium sulfate 20~25%, high hydroscopic resin particle 15~20%, sodium metasilicate 5~10%, starch ether 3~5%, cellulose ether 2~3%, dispersant 1~5%, surplus are water.The present invention blocks concrete surface stomata by penetrant crystalline, and high hydroscopic resin can go into one layer of continuous fine and close mucous membrane structure to reduce scattering and disappearing for moisture in concrete surface, and due to the water imbibition of high hydroscopic resin, and the relatively low moisture that can be absorbed in air of saturated vapour pressure of magnesium sulfate to absorb moisture enhancing moistening effect from air, hence it is evident that improves early strength of concrete.
Description
Technical field
The invention belongs to concrete curing agent technical fields, and in particular to a kind of mucosal pattern curing compound and its system
Preparation Method.
Background technology
Concrete has irreplaceable role as current most one of the material of dosage in the world in engineering.It is mixed
The quality for coagulating soil plays a decisive role to engineering service life, and the performance of concrete is in addition to direct with raw material property, match ratio
Mutually also have outside the Pass with the maintenance in later stage it is inseparable contact, if concrete curing is not in time, internal moisture will lead to
It crosses pore and is evaporated to the external world, keep cementitious material aquation insufficient, hydrated product is reduced, to make the performance of concrete various aspects
It declines to a great extent.Traditional concrete curing mode includes mainly：Water curing, steam curing, landfill maintenance and covered rearing with plastic film
Deng there are time-consuming and laborious, conserving the problems such as not in place.Curing agent maintenance process is to spray curing agent or brush in concrete
Surface forms the curing in airtight condition film for preventing water evaporation in concrete surface, has relative to traditional maintenance method easy to operate, foster
Protect the advantages that effect is good.
The curing compound in China mainly includes type and inorganic type two major classes at present.Inorganic type curing agent include with
Curing agent based on waterglass or sulfate, maintenance principle is to infiltrate through concrete surface micropore and hydrated product Ca (OH)2
Reaction generates calcium silicates colloid and forms dense film, blocks surface micropore by volume expansion, prevents moisture evaporation.Sulfate with
Ca(OH)2A large amount of ettringite acicular crystal obstruction concrete surface stomatas are generated, the evaporation of moisture is further decreased.Organic type
Curing agent includes mainly macromolecule emulsion and paraffin wax emulsions curing agent etc., and maintenance principle is macromolecule emulsion in concrete surface
One layer of film with flexibility, caking property is formed after drying, and deadend is carried out to concrete surface, it is low-moisture to drop
Evaporation.
The problems such as inorganic type curing agent there is water retentions low, film water solubility is poor, in the shadow of temperature and rain and fog weather
It is susceptible to phenomena such as cracking falls off under sound.The emulsion system of organic type curing agent is easily influenced by temperature and occurs being demulsified and wad a quilt with cotton
Coagulation phenomena, and the problem of be susceptible to plug nozzle and sebific duct in the construction process.Organic-inorganic compoiste curing agent can be sent out
The advantage of both inorganic curing agent and organic curing agent is waved, collaboration promotes the maintenance effect of concrete, is the hair of the following curing agent
Open up direction.Chinese patent CN 103496037B disclose a kind of maintenance process of concrete component, although using resin and salt
Organic mineral complex system is as curing agent, but the curing agent does not have wettability power and curing step is cumbersome.
Invention content
It is a kind of with good the technical problem to be solved by the present invention is to aiming at the above shortcomings existing in the prior art, provide
The mucosal pattern curing compound and preparation method thereof of good moisturizing, wettability power.
In order to solve the above technical problems, technical solution provided by the invention is：
A kind of mucosal pattern curing compound is provided, its raw material group becomes by mass percentage：Anhydrous magnesium sulfate 20~
25%, high hydroscopic resin particle 15~20%, sodium metasilicate 5~10%, starch ether 3~5%, cellulose ether 2~3%, dispersant 1
~5%, surplus is water.
By said program, the high hydroscopic resin particle is one kind in Sodium Polyacrylate particle, polyvinyl alcohol.
By said program, the sodium metasilicate is one in instant powdered sodium metasilicate, sodium silicate solid or liquid sodium silicate
Kind is several.
By said program, the starch ether is the hydroxypropyl starch ether of Shandong Enrique Miguez Gómez Chemical Co., Ltd. production.
By said program, the dispersant is in ethylene group bis-stearamides (EBS), glyceryl monostearate (GMS)
It is at least one.
The present invention also provides the preparation methods of above-mentioned mucosal pattern curing compound, and its step are as follows：
1) raw material is weighed by material quality per distribution ratio, it is spare；
2) anhydrous magnesium sulfate and sodium metasilicate are added to the water, stir to get anhydrous magnesium sulfate and sodium metasilicate mixed solution；
3) high hydroscopic resin particle is added in anhydrous magnesium sulfate and sodium metasilicate mixed solution obtained by step 2), is added
Starch ether and cellulose ether, are eventually adding dispersant, stir evenly, and obtain mucosal pattern curing compound.
Mucosal pattern curing compound prepared by the present invention sprays after can both being dissolved by solvent, can also first soak coagulation
Native surface, then the mucosal pattern curing compound of dry powder-shaped is sprayed on concrete surface.
The present invention proposes a kind of curing agent of organic-inorganic compoiste, and organic moiety is selected high hydroscopic resin, had
Good wettability power, and one layer of fine and close mucous membrane can be formed in concrete surface, inorganic part uses magnesium sulfate, magnesium sulfate
Mg (OH) is generated with the calcium hydroxide reaction generated after hydrated cementitious2And CaSO4, surface more densely cross-linkedization, and sulfuric acid can be made
The saturated vapor pressure of salt is relatively low, there is certain wettability power.By above-mentioned synergistic effect, densification surface forms fine and close mucous membrane
Come while reducing moisture loss, high hydroscopic resin can absorb moisture to improve maintenance effect from air.
The beneficial effects of the present invention are：1, curing agent provided by the invention generates Mg (OH) in concrete surface2With
CaSO4Precipitation energy blocking surface stomata weakens scattering and disappearing for moisture, and super absorbent resin fat liquor can form fine and close mucous membrane, into one
Step prevents scattering and disappearing for moisture, magnesium sulfate salt to have the energy for absorbing moisture in certain slave air because of its lower saturated vapour pressure
Power, to achieve the effect that moisturizing；2, the production process of the curing agent is simple, easy to operation, is easy to industrialized production, tool
There is great economic value.
