Described multifunctional mortar additive, its weight part proportioning is:
27.1 parts of rosin;
4.9 parts of soda ash;
3 parts in tartrate;
5.7 parts of tri-isopropanolamines;
5 parts in ferrous sulfate;
50 parts in water.
The effect of each composition among the present invention: rosin is the oleo-resinous that pine tree is obtained, and abietic anhydride and sylvic acid account for 80% in the Chemical Composition, and the rosin hydrocarbon accounts for 5-6%, and rosin belongs to micro foam agent, improves the workability of mortar, instead of part or whole lime; The chemical name of soda ash is a strong base-weak acid salt in yellow soda ash, has neutralizing effect, belongs to hardening accelerator; Tartrate is a kind of carboxylic acid, belongs to antioxidant; Tri-isopropanolamine belongs to hardening accelerator, belongs to organic amine hardening accelerator; Ferrous sulfate belongs to hardening accelerator; Water is rare thick material.
The preparation method of multifunctional mortar additive of the present invention: earlier water is heated, add rosin, make its abundant saponification, add tartrate, add soda ash, add ferrous sulfate, add tri-isopropanolamine, when reinforced, to constantly stir, be heated to 70-95 ℃ at last, be incubated 15-180 minute, promptly can be made into multifunctional mortar additive of the present invention.Insulation is preferable about 60 minutes.
The using method of multifunctional mortar additive of the present invention: press 0.5 * 10 of mortar consumption
-4To 1.5 * 10
-4Ratio get multifunctional mortar additive of the present invention, again in 1: 10 ratio thin up of multifunctional mortar additive consumption, the multifunctional mortar additive and the mortar that will add behind the water stir and can use.In use, plastering construction is pressed GB50210-2001 " building decoration engineering acceptance specification " execution; The masonry construction is pressed GB50203-2002 " code for construction and acceptance of masonry structure engineering " and is carried out; Determining of mortar mix ratio according to JGJ98-2000 " masonry mortar proportioning design discipline ", and according to the material material and the mortar mark of working-yard, joined by examination, determines rational proportioning.
Beneficial effect of the present invention: the workability of significantly having improved mortar; Increase the mortar capacity, improve the water retention property of mortar; Effectively improve ultimate compression strength, anti-permeability performance, the anti-freezing property of mortar; Improve the adhesive capacity of mortar; Save lime, water, cement, reduce construction costs.
