Abstract
The invention discloses a waterproof mortar suitable for a high-humidity environment. The waterproof mortar comprises the following components in parts by weight: 8-15 parts of high-aluminum cement, 15-25 parts of Portland cement, 30-50 parts of quartz sand, 5-10 parts of synthetic gypsum, namely CaSO4, 15-25 parts of lime powder, namely CaCO3, 1-5 parts of distributed latex powder, 3-10 parts of waterproof agent, 0.1-1.5 parts of defoaming agent, and 0.5-2 parts of shrinkage reducing agent. The waterproof mortar is applicable to high-humidity regions of southwest China, and waterproof engineering with harmful cracks due to humidity, temperature, structure change, vibration and the like cannot be caused. The compaction and crack resistance of the mortar can be enhanced so as to achieve the waterproof and anti-seepage requirements.
Description
Technical field
The present invention relates to waterproof mortar of a kind of applicable high humidity environment use and preparation method thereof.Relate to building material technical field.
Background technology
Along with country adopts the universal of various new wall materials and energy-saving low-carbon technology and promotes at building field, mortar for building is functionalization and specialization increasingly.All kinds of extraordinary mortars, as: heat insulating mortar, the special-purpose assorted mortar of aerated-block, gravity flowing levelling mortar etc. arise at the historic moment, its feature is all on the basis of traditional sand-cement slurry, to add various functional high-polymer polymer materialss, to meet different purposes, different performance requires every physics, the chemical index requirement of mortar.Waterproof mortar involved in the present invention is a kind of rigidity water-proofing material, by improving the density of mortar and improving splitting resistance to reach the object of water proof anti-seepage, mainly be applicable to Southwest China high humidity environment area, can be used for not producing because of humidity, temperature, structural changes and vibrated etc. the waterproofing work of harmful cracks simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of applicable high humidity environment area and uses, and ecological, environmental protective, superior performance, cost waterproof mortar reasonable, easy to use and preparation method thereof.
In order to solve the problems of the technologies described above, the invention provides a kind of waterproof mortar, its component by following weight part forms: high-alumina cement 8-15 part, silicate cement 15-25 part, quartz sand 30-50 part, synthetic gypsum (CaSO

3) 15-25 part, dispersible formula latex powder 1-5 part, water-resisting agent 3-10 part, defoamer 0.1-1.5 part, economization agent 0.5-2 part.
The present invention also provides the preparation method of above-mentioned waterproof mortar simultaneously, and its method and step are as follows:
1), by ferric oxide (Fe
2o
3), hydrochloric acid (HCl), Tai-Ace S 150 (Al
2(SO
4)
3) be mixed in proportion rear stirring 10-30 minute, obtain water-resisting agent of the present invention.
2), by step 1) gained water-resisting agent and high-alumina cement, silicate cement, quartz sand, synthetic gypsum (CaSO
4), lime powder (CaCO
3), dispersible formula latex powder, defoamer, economization agent and put into 20-30 minute after totally-enclosed stirrer by component, gained mixture is crossed to 0.315mm sieve, packing, obtains finished product of the present invention.
Above-mentioned steps 1), step 2) all under whipped state, complete, rotating speed is 1000～2000 revs/min.
The beneficial effect of the technical program: be applicable to Southwest China high humidity environment area, can be used for not producing because of humidity, temperature, structural changes and vibrated etc. the waterproofing work of harmful cracks simultaneously.The density of raising mortar, splitting resistance are to reach the requirement of water proof anti-seepage.
