Abstract
The invention discloses a kind of corrosion-resistant mortar, comprise following raw material: cement, blast furnace slag, potter's clay mine tailing, sand, emulsifying agent, defoamer, calcium formiate, Vltra tears, Ying Zhi Suan Magnesium, hydroxypropyl starch ether, Gluconolactone.The present invention has the following advantages compared to existing technology: the proportioning raw materials optimizing mortar, under given conditions modified-reaction is carried out to mixtures such as the cement in mortar, add sand after reaction again and prepare mortar under given conditions, cement body and aggregate is made to form strong bonding, mortar product has stronger resistance to corrosion, energy acid-and base-resisting, salt and the corrosion of other chemical, resistance to high humidity, ageing-resistant, except for except concrete reinforcing and repairing, the building that chemical industry groove, chemical industry warehouse, refuse landfill etc. need chemically to corrode can also be used for.
Description
Technical field
The invention belongs to architectural chemistry Material Field, be specifically related to a kind of corrosion-resistant mortar and preparation method thereof.
Background technology
Mortar is one of most widely used in current world wide, that consumption is maximum material of construction, adopt ordinary Portland cement, dry hydrate, quartz sand, Paris white, talcum powder etc. to add methyl or Vltra tears etc. more, add redisperable polymer powder in addition again and be made into mortar or become polymer mortar with polymer emulsion co-formulation.
By constantly studying and improving, existing mortar has excellent bonding, cracking resistance, freeze proof, antiseepage, chloride-penetration resistance, ageing-resistant performance, the scope of application increases greatly, is applicable to steel construction and the antiseepage of skeleton construction, anticorrosion mask and the repairing works such as ocean, sluice, waterfall, port engineering, highway, bridge, metallurgy, chemical industry, industry ground slab and covil construction.At special occasions, need to use the mortar with erosion resistance, current existing corrosion-resistant mortar mainly contains following four kinds: acid resisting mortar, sulphur acid resisting mortar, the mortar of resistance to ammonium and alkaline-resisting mortar, but its function is relatively single, cause the shortcoming that Application Areas is little, therefore the research of corrosion-resistant mortar and processing technology need further to improve.
Summary of the invention
The object of the invention is for existing problem, provide a kind of corrosion-resistant mortar and preparation method thereof.
The present invention is achieved by the following technical solutions: a kind of corrosion-resistant mortar, include the raw material of following weight part: cement 20-25 part, blast furnace slag 5-8 part, potter's clay mine tailing 6-10 part, sand 55-65 part, emulsifying agent 2-4 part, defoamer 0.5-1 part, calcium formiate 0.2-0.4 part, Vltra tears 0.3-0.6 part, Ying Zhi Suan Magnesium 0.1-0.3 part, hydroxypropyl starch ether 0.02-0.06 part, Gluconolactone 0.04-0.08 part.
As further improvement of these options, described cement to be strength grade be 42.5 silicate cement and strength grade be the mixture of the sulfate resisting Portland cement of 37.5, blending ratio is 4:1.
As further improvement of these options, described sand is selected from mountain sand, light sand sea sand or Machine-made Sand, and its fineness modulus is 1.6-2.0.
As further improvement of these options, described emulsifying agent is sorbitan fatty acid ester, sylvic acid polyoxyethylene, fatty alcohol-polyoxyethylene ether, the one in lauric acid Soxylat A 25-7 or hydroxylated alkyl groups Soxylat A 25-7.
As further improvement of these options, described defoamer is the mixture of in polyethers, phosphoric acid ester, silicone oil, higher alcohols, vegetables oil, mineral oil at least two kinds.
A preparation method for corrosion-resistant mortar, comprises the following steps:
(1) cement, blast furnace slag, potter's clay mine tailing being finely ground to granularity is 180-200 order, puts into stirrer and stirs;
(2) in powder mix, add the water suitable with its total mass and hydrochloric acid, controlling its pH value is 5.5, and adds the calcium formiate of corresponding deal, Ying Zhi Suan Magnesium, hydroxypropyl starch ether and Gluconolactone, leaves standstill 6-8 hour after stirring;
(3) in step (2) gained mud, add sand, the water of sand weight 10%, lactic acid agent, defoamer and hydroxy-methyl cellulose, control temperature, at 35-45 DEG C, stirs 2-4 hour, obtains mortar finished product.
The present invention has the following advantages compared to existing technology: the proportioning raw materials optimizing mortar, under given conditions modified-reaction is carried out to mixtures such as the cement in mortar, add sand after reaction again and prepare mortar under given conditions, cement body and aggregate is made to form strong bonding, mortar product has stronger resistance to corrosion, energy acid-and base-resisting, salt and the corrosion of other chemical, resistance to high humidity, ageing-resistant, except for except concrete reinforcing and repairing, the building that chemical industry groove, chemical industry warehouse, refuse landfill etc. need chemically to corrode can also be used for.
