Abstract
The additive for cement mortar and lime motar used for building is prepared with waste reed pulp liquid as main raw material, soda, rosin and triethanolamine and features that its raw materials also include talloel and dodecanol sodium sulfate for increasing flowability, strength and cementing nature and decreasing air bubbles.
Description
The present invention relates to mortar additive for building.
The mortar additive that is adopted in the existing building industry has micro foam agent, fluidizer etc., its major defect is to cost an arm and a leg, and must add the hot water dissolving, just can mix in the mortar, in use can only partly substitute the lime in the mixed mortar, when preparation low grade mortar, because the sand consumption is too much, workability can not get obvious improvement; When adopting cement of high index preparation low grade mortar, because cement mark is too high, promptly cement consumption is few, the sand consumption is many, and mortar can produce layering, from wash rice and bleeding, that is to say to occur that sand sinks, the grout come-up, on the mixture surface seeping phenomenon is arranged, promptly workability is bad.Its poor water retention property of mortar that workability is bad can produce desciccation crack after curing, influence mortar strength, and it is mobile poor, is not easy to the operation construction.
The objective of the invention is to overcome above-mentioned defective, a kind of easy dissolving, intensity height are provided, can significantly improve in mortar workability and the alternative mixed mortar all mortar additives of lime.
Technical scheme of the present invention: be in existing mortar additive, to add tall oil (tallol) and two kinds of compositions of sodium lauryl sulfate, make it increase the flowability of mortar, reduce cement granules accumulative trend, destroy the flocculation tissue that cement granules produces, make the abundant aquation of cement simultaneously, reduce the quantity of harmful pore, improve mortar strength.
Concrete prescription of the present invention: the tankage spent pulping liquor (reed pulp waste liquid) with papermaking is main raw material, be equipped with brown colloidal liquid or coccoid that soda ash, rosin, trolamine, tall oil (tallol) and sodium lauryl sulfate are formed, its weight proportion is as follows:
100 parts of spent pulping liquors
2.5～4 parts of rosin
2～4 parts of soda ash
2～4 parts of trolamines
4～6 parts of tall oils (tallol)
0.5～1.0 part of sodium lauryl sulfate
Blending process of the present invention: according to above-mentioned component weight proportion, when at first soda ash and spent pulping liquor being put into 80 ℃ to 100 ℃ of assorted pot heating, add pulverous rosin in the pot then and stir, after rosin adds, heated 60 minutes, and made its abundant saponification; Add tall oil (tallol) again, after continuing to boil 60 minutes, be pumped in the closed mixer, make and saponifiedly strengthen, fully decompose its Mierocrystalline cellulose in the stirrer high speed, fully strengthen after 10 minutes, be discharged in the charging basket, be cooled to normal temperature after, be equipped with trolamine, sodium lauryl sulfate again, promptly become the colloidal liquid finished product through stirring, or the adding powder becomes the coccoid finished product.
The present invention is a kind of anion surfactant of hydrophobic type, also is a kind of negative particle,colloid; Tall oil adding of the present invention wherein produces emulsification and lubrication; Sodium lauryl sulfate is a kind of infusion that draws.The present invention adds in the mortar can play diffusion to cement granules, reduces cement granules accumulative trend, destroys the flocculation tissue that cement granules produces, and discharges the water that is surrounded by cement granules, increases the flowability of mortar, reduces water consumption, reduces water cement ratio; And make the abundant aquation of cement, and structure is closely knit, and intensity improves.The foaming effect of sodium lauryl sulfate is introduced many small stabilise bubbles in mortar, reduce the quantity of harmful pore, improves mortar strength.Simultaneously, bubble destroys the capillary channel of mortar in mortar, and excreting water phenomenon reduces, and does not produce layering, and water-retentivity improves.Because the present invention has improved the flowability and the water-retentivity of mortar, make mortar become soft plastic, high resilience can increase the powder junction area of brick when building by laying bricks or stones, improve cohesive force and plumpness.
The present invention after tested, the present invention not only is applicable to sand-cement slurry, and is applicable to lime mortar, can save lime more than 40% for lime mortar, and can substitute whole lime in mixed mortar; And can save the cement more than 20%, seven days intensity of mortar improves more than 40%, and intensity improved more than 30% in 28 days.In whitewashing, mortar bonding power is strong, can overcome to flake and phenomenon such as cracking; Use every cubic metre of masonry mortar of the present invention can reduce by 20～35 yuan of materials cost, 75～100 yuan (comparing) of every cubic metre of whitewash mortar economical with materials expense, 15～25 yuan (comparing) with sand-cement slurry with lime mortar;
In sum, the present invention has good intensity, improves the mortar workability greatly, can substitute the whole lime in the mixed mortar, saved cement, use the present invention, can obtain good economic benefit, simultaneously, main raw material of the present invention is a spent pulping liquor, turn waste into wealth like this, help environment, its obvious social benefit.
Claims (1)
1, a kind of efficient mortar additive, it is that tankage spent pulping liquor (reed pulp waste liquid) with papermaking is raw material, be equipped with the brown colloidal liquid or the coccoid of soda ash, rosin, trolamine composition, it is characterized in that being furnished with in the described mortar additive tall oil (tallol) and two kinds of compositions of sodium lauryl sulfate, the weight proportion of its admixture component is as follows:
100 parts of spent pulping liquors
2.5～4 parts of rosin
2～4 parts of soda ash
2～4 parts of trolamines
4～6 parts of tall oils (tallol)
0.5～1.0 part of sodium lauryl sulfate
