Abstract
This invention relates to a basic material of a high efficient mortar DBP to be prepared by the following method: a, adding 11-14% rosin polymers into 45-55% water of 80-120deg.C slowly and mixing them in a kettle continuously to be solved fully, then adding 4-6% inorganic alkali and dissolving them completely under the 60-80deg.C constant to the complete reaction, b, adding 8-10% sulfosalt while mixing, 1-2% polyalcohol under 40-60 deg.C constant to the complete reaction, c, adding 10-11% DBP to be dissolved fully under 30-50 deg.C to be cooled to normal temperature, d, spraying and drying them to powder particles then to be matched with 3-5% DBP and 9-11% silicon powder to get the basic material of high efficient mortar DBP. This invention also relates to its compound.
Description
Technical field
The present invention relates to a kind of mortar additive, particularly a kind of efficient mortar plasticizer base material and preparation method thereof, and efficient mortar plasticizer composition.
Background technology
In industry and civil building engineering, to build by laying bricks or stones and use very commonly with motar, China's building mortar is annual to be needed with billion cubic meter more than 10, use cement 2～300,000,000 ton, lime putty 1～200,000,000 ton.In order to satisfy the workability of mortar, past is mainly by the cement consumption of increase by 20～30% or mix the lime putty of cement consumption 30～100%, consequently, increase cement consumption, increase cost, the mortar working property improvement is not obvious, it is very serious to use lime putty that the workyard is polluted, and the motar metope is cracked hollowing, come off, construction quality is affected;
After the eighties, build by laying bricks or stones with motar in mix colophonium pyrolytic polymer air entrapment agent replace lime cream, it can significantly improve the mortar workability, but its major function be introduce a large amount of apertures at the bubble of 300～500 μ m in mortar, these big and many bubbles slide between the mortar particle as ball mixing and stirring in the process of mortar, mortar working is improved, because the existence of a large amount of bubbles in the mortar, mortar strength descends significantly, generally decrease by 40～60%, make construction quality be subjected to heavy losses.
In mortar, use micro foam agent, volume is ten thousand/several to 100,000/several, measure very difficultly, the volume deficiency can not improve workability, volume is too much, the mortar strength range of decrease is too big, construction quality is had a strong impact on; On the other hand, micro foam agent is a liquid, and winter temperature is low, needs heating for dissolving, otherwise can't use, and brings difficulty to construction, thus micro foam agent promote the use of the restriction that is subjected to implementation management department in recent years.
The present active ingredient for mortars that occurs on the market, the mortar king, use under construction, also can replace lime cream, play the effect that improves mortar working, but it is a kind of modification of micro foam agent product, promptly change solid into by liquid, become the doping level of some thousandths of by ten thousand/several doping level, it is easy to use, preserve, free from environmental pollution, but its dominant mechanism is bleed type product, also be to play the effect that improves the mortar workability by introducing a large amount of bubbles in mortar, its mortar strength also can descend 30～40% than benchmark mortar strength, can not guarantee construction engineering quality, because the reduction of intensity has only by increasing cement consumption to remedy loss of strength.
Summary of the invention
The technical problem to be solved in the present invention provides and a kind ofly solves the existing technical problem of building mortar, can guarantee that the raising of serviceability can guarantee construction quality again, the efficient mortar plasticizer base material that can also reduce production costs and preparation method thereof and efficient mortar plasticizer composition.
Technical scheme provided by the invention is: a kind of efficient mortar plasticizer base material, calculate by overall weight percent, and this efficient mortar plasticizer base material can be prepared from by following method, and this method may further comprise the steps:
It is in 80～120 ℃ the water that a, the rosin polymer with 11～14% slowly join 45～55% temperature, and in reactor, constantly stir, after it is fully dissolved, add 4～6% mineral alkali again, wherein mixing and stirring the moisture application boiling water that reduces in the process in dissolving supplies, after the dissolving fully, under 60～80 ℃ temperature, constant temperature is up to complete reaction;
B, under 60～80 ℃ temperature, stir and limit adding sulfonate 8～10% on the limit, trolamine or three b propanol amine 1～2%, under 40～60 ℃ temperature, constant temperature is up to complete reaction;
C, add 10～11% softening agent again, it is fully dissolved, and after reacting completely under 30～50 ℃ of temperature, be cooled to normal temperature;
D, be spray dried to Powdered particle, composite with thickening material 3～5% and silicon powder 9～11%, promptly obtain efficient mortar plasticizer base material.
