Abstract
The invention discloses a multifunctional highly performance waterproofing agent, which comprises plasticizing agent, air-entrainer, organic material, reduction material, the invention can be utilized to obtain water solution and powder preparation.
Description
Technical field
The present invention relates to the water-resisting agent, particularly Multifucntional water-proof agent with special effect used on a kind of building materials.
Background technology
Along with the development of Building Trade in China, Highrise buildings, bridge and underground civil air defense constructions and installations increase year by year.Because the maximization of engineering structure, complicated and concrete production and operating technique have proposed more technical requirements day by day to mechanize, modernization and commercialization development for the rigidity water-proofing material that mixes in the concrete.Present common water-resisting agent exists function singleness, poor performance, comprehensive cost is high and expanded polystyrene veneer water-resisting agent curing requirements high and the technological deficiency of constructional difficulties and mix simultaneously multiple admixture produce sometimes consistency bad with shortcoming such as the trouble of constructing.Though the water-resisting agent of construction market application now is of a great variety, the main branch: two kinds of pulvis and liquid waterproof agents.Pulvis water-resisting agent and swelling agent etc. mix and mainly play the compensate for shrinkage waterproof action in the concrete, if adopt the pumping construction concrete then must be compound other admixture, could satisfy construction technical requirement as pumping agent, water reducer etc.Building the multifunctional water-proofing agent of grinding institute's development as Chinese building material institute and China all is that expanded polystyrene veneer pulvis water-resisting agent and its incorporation are higher, 8～12% of about by mass of cement.In commerical ready-mixed concrete, must establish the special messenger and feed intake, and dust is big, the labour intensity height, alkali content is high and because of measuring the inaccurate maintenance accident resulting from poor quality of projects that easily causes not in place.The liquid repellent agent of domestic application mainly contains Indian red class water-resisting agent, fatty acid and inorganic aluminate class water-resisting agent etc., and incorporation is about 2～3%.They mix and mainly play the water proof anti-seepage effect in the concrete.Effect such as do not have pumping, reduce, the concrete pumping construction must add admixtures such as pumping agent or water reducer.Only have the water-resisting agent of single water-proof function and the needs that swelling agent can not satisfy development of the situation obviously.
Through international online retrieval, the cement of finding relevant silicone ingredients is alkyl, alkoxyorganosilane, halogen organosilane, organic second vinegar base silane etc.Relevant multifunctional water-proofing agent (JP09-303316) includes the crosslinked non-cationic both sexes third rare acyl group styrene polymer water-resisting agent of alkali, water reducer and water-holding agent; (publication number is: CN1161312) " novel high-efficiency water-proof agent " (CN1194290) for Chinese patent disclosed " a kind of mortar and concrete water-resisting agent ".Mainly acting on by its contained proximate analysis is water proof anti-seepage.
For this reason, publication number contains compositions such as organosilicon, water reducer, sodium lignosulfonate or calcium lignin sulphonate, citric acid, Tai-Ace S 150 or aluminum nitrate for the CN1098227C Chinese patent discloses a kind of multifunctional water-proofing agent for concrete.Though this multifunctional water-proofing agent for concrete collection high-effective water-proof, diminishing, be pumped to one and have a multi-functional liquid repellent agent of microdilatancy.Incorporation is low, can satisfy the pumping construction technical requirements of big fluidised form water-proof concrete.After commerical ready-mixed concrete mixed water-resisting agent, can play waterproof action did not need admixtures such as admixture pumping agent, water reducer just can satisfy concrete guarantor again to mould and the pumping requirement.But its key technical indexes still is not ideal enough, as its density: 1.20g/ml-1.25g/ml; Solid content: 40-50%; Water-reducing rate: 14-20%; Flowing degree of net paste of cement: 210-240mm; Amount of air entrainment :≤4.0%; Compressive strength rate: 3d≤140,7d≤143,28d≤134.Permeated height ratio: 〉=27%.In addition, this water-resisting agent adopts organosilicon, thereby the restriction in work-ing life is arranged, and calcium lignin sulphonate easily goes out engineering accident with partly consistency is bad.The incorporation of swelling agent is wanted strict control.Swelling agent is mixed few, and it is invalid can not expand, and how has mixed, and concrete quality descends.And it is bigger to expand, and the later stage shrinks bigger.The swelling agent maintenance is difficulty also, and maintenance is bad and can have the opposite effect, and is more easy to crack.Use swelling agent can make concrete alkalinity height, easily produce alkali-aggregate reaction.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned water-resisting agent, provide a kind of and collect high-effective water-proof, diminishing, be pumped to Multifucntional water-proof agent with special effect one and that have good technique index, low-dosage.
