Acid type auxiliary agent improves the intensity in gypsum use, but the use of these auxiliary agents, especially sulfuric acid and phosphoric acid brings environment and asks
Topic；Certainly also someone's report utilizes sodium lignin sulfonate, magnesium lignosulfonate, calcium lignosulfonate, melamine, naphthalene system diminishing
The wider array of application range of gypsum, although there is certain effect to a certain extent, these auxiliary molecules amounts are expanded in the improvement such as agent
It is smaller, structure is simple, be still not achieved it is envisaged that effect, in addition naphthalene water reducer production technology be responsible for, environmental pollution is tight
Weight does not meet the strategy of national green development.Therefore a kind of gypsum reinforcing agent is developed, while improving gypsum dry and wet intensity also not
Can affect to environment is current focus concerned by people.
Summary of the invention
In view of this, the present invention provides a kind of gypsum highly efficient intensifying agent, main purpose be by being grafted between small molecule,
Composite structure complexity, the stronger gypsum reinforcing agent of peptizaiton have dispersion gypsum particle to reduce water paste ratio after compounding, lead to
Chemical action enhancing gypsum intensity is crossed, and then also avoids bring problem of environmental pollution in other gypsum auxiliary agent production processes.
In order to achieve the above objectives, invention broadly provides following technical solutions:
On the one hand the present invention provides a kind of gypsum highly efficient intensifying agent preparation method, the method includes following procedure:
A kind of gypsum highly efficient intensifying agent be mainly mixed in a certain ratio by organic high molecular polymer and inorganic salts form it is water-soluble
Liquid, wherein organic high molecular polymer accounts for 4 ~ 8 parts, and inorganic salts account for 2 ~ 5 parts.
Preferably, the organic high molecular polymer is polycarboxylic acids, polycarboxylate, methyl cellulose ether, polyethylene glycol
Or the one kind of polyacrylamide at least within.
Preferably, the polycarboxylic acids is made of the mixture of polyacrylic acid and poly, average molecular weight distribution
Between 8000 ~ 15000；Methyl cellulose ether average molecular weight is distributed between 200000 ~ 250000；Polyethylene glycol is averaged
Molecular weight distribution is between 6000 ~ 12000；Polyacrylamide average molecular weight is distributed between 6000 ~ 10000.
Preferably, the polycarboxylate is that Sodium Polyacrylate or calcium polyacrylate (CPA) are one such.
Preferably, the inorganic salts are the one kind of sodium chloride, calcium chloride, sodium sulphate or calcium sulfate at least within.As
It is preferred that the organic high molecular polymer accounts for 4 ~ 8 parts, inorganic salts account for 2 ~ 5 parts.
On the other hand, a kind of gypsum highly efficient intensifying agent is made using the above method in the present invention.
Compared with prior art, the beneficial effects of the present invention are:
The present invention relates to the method for preparing efficient gypsum reinforcing agent, technological operation is simple；Raw material is cheap and easy to get, reduces and is produced into
This；
The present invention relates to efficient gypsum reinforcing agent is prepared, by preparation structure after grafting, compounding between small molecule, complicated, dispersion is made
With stronger gypsum reinforcing agent, to reduce water paste ratio.
