Abstract
The present invention relates to a nano-silicon waterproof agent for the field of construction and a production method thereof, which comprises two major contents: 1. the ingredients of the nano-silicon waterproof agent comprise an organosilicon waterproof agent, nano-class silicon powder, polymer emulsion, a catalysis auxiliary agent and water. The organosilicon waterproof agent is methyl silicone sodium alcoholate, or high boil silicon sodium alcoholate, or methyl Sodium silicate or methyl Potassium silicate; the nano-class silicon powder is nano-class silicon dioxide; the polymer emulsion is styrene-acrylate emulsion, or pure acrylic emulsion or silicone acrylic emulsion; the catalysis auxiliary agent is ethanolamine, or diethanolamine or triethanolmine; and the water is deionized water. 2. in the production method, the organosilicon waterproof agent, the nano-class silicon powder, the polymer emulsion and the catalysis auxiliary agent are proportionally mixed and then are heated and stirred, the mixture is thoroughly reacted for 4 hours; after the mixture is tested, right amount of the deionized water is added, and the final product is obtained. The nano-silicon waterproof agent has the advantages that 1. the nano-silicon waterproof agent is sprayed on the building surface; on the basis of keeping primal color, the nano-silicon waterproof agent can penetrate in the inner part of building materials and form a compact solid net structure, the pores are plugged, and the nano-silicon waterproof agent has the functions of water prevention and seepage resistance for a long time; 2. the nano-silicon waterproof agent mixed with cement mortar and cement is used as additives, and the nano-silicon waterproof agent has the excellent waterproof properties which are more incomparable than the waterproof properties of the same kind of additives.
Description
Technical field the present invention relates to a kind of water-resisting agent that is used for building field.The nano-silicon water-resisting agent and the production method that particularly relate to a kind of high-performance permeable crystallization type.
The existing both at home and abroad rigid waterproofing agent that is used for the permeable crystallization type of building field of background technology has: very clear water-resisting agent, and the wall gram leaks, and ten thousand can be coated with, SR900, spray is leaked and is stopped M1500 etc.Above-mentioned several water-proof material can only be used for spraying, and is difficult for using as admixture, so the restriction that is under many restrictions of its use range.Existing can be as having that admixture uses: aluminate water-proof agent, FS-A1 water-resisting agent, five alum water-resisting agents, iron(ic) chloride water-resisting agent, waterproofing agent of organosilicon etc." waterproofing agent of organosilicon " wherein is though there is certain spraying water proof anti-seepage function, and the ability of its perviousness and the big pore of obstruction is difficult to satisfy the needs of engineering; The serious slow setting and the strength degradation of its Cement Concrete that causes or mortar also are its fatal weakness when doing the admixture use.
Summary of the invention the object of the present invention is to provide a kind of water-proof function that excellence is not only arranged in spraying, and makes also to have when admixture uses the nano-silicon water-resisting agent and the production method of excellent water resistance.
Technical scheme of the present invention is:
1, a kind of nano-silicon water-resisting agent comprises following composition:
(1) sodium methyl silicate or methyl silicon sodium alcoholate or high boiling Sodium silanolate 92 ~ 98%
(2) nanometer grade silica 1 ~ 5%
(3) organosilicon crylic acid latex or benzene emulsion or pure-acrylic emulsion 0.5 ~ 1.5%
(4) Monoethanolamine MEA BASF or diethanolamine or trolamine 0.5 ~ 1.5%
(5) deionized water is an amount of
(6) wherein the total amount of each component is 100%.
2, the production method of the nano-silicon water-resisting agent told of a kind of claim 1, it is characterized in that: with sodium methyl silicate or methyl silicon sodium alcoholate or high boiling Sodium silanolate, nanometer grade silica, organosilicon crylic acid latex or benzene emulsion or pure-acrylic emulsion, Monoethanolamine MEA BASF or diethanolamine or trolamine, deionized water, in mixing in the described ratio stirring of claim 1 and being heated to 95 ℃, do not stop to stir abundant reaction 4 hours, it is 100% to get final product that check back replenishes deionized water to total amount.
The present invention compared with prior art has following advantage:
1, sodium methyl silicate in the nano-silicon water-resisting agent or methyl silicon sodium alcoholate or high boiling Sodium silanolate and nanometer grade silica by with cement or masonry neutral and alkali substance reaction, generation has the material and the phyllosilicate crystal grain of strong hydrophobic nature, improve mortar, concrete hydrophobic impermeability, strengthen the density of its structure, stop up big pore.This comprehensive synergy is when playing water proof anti-seepage, and less pore can also see through gas, is unlikely to make indoor too moist; Also can improve mortar, concrete resistance to compression, tensile strength, improve splitting resistance, weather resistance realizes the permanence waterproof.
2, organosilicon crylic acid latex in the nano-silicon water-resisting agent or benzene emulsion or pure-acrylic emulsion do not have chemical corrosion to concrete inside reinforcing bar, and it can help concrete and mortar oneself maintenance, prevent to cause local doing earlier to produce crack performance because of tanning by the sun with the temperature difference.
3, Monoethanolamine MEA BASF in the nano-silicon water-resisting agent or diethanolamine or trolamine have the performance of improving sand-cement slurry, Cement Concrete hydration reaction, and have the effect of resistance rust.Thereby make this water-resisting agent have the chemical-resistant resistance of the excellence different, ageing resistance, stain resistance with other water-proof material.
4, the nano-silicon water-resisting agent has good frost resistance.It can prevent that building surface generation fragment from coming off.Porous advances in many class opaques, the aqueous coating metope, and plays the water proof anti-seepage effect.
5, nano-silicon water-resisting agent salt tolerant, alkali, and certain acid resistance is arranged; Applicable to salt, alkali content height, the buildings that influenced by oceanic climate.
6, nano-silicon water-resisting agent adaptability is strong, and the quality guaranteed period reaches 5 years.All can construct more than 5 ℃ at temperature throughout the year, after construction is solidified, but heatproof-70 ℃ to 180 ℃, once construction, lifelong waterproof.Therefore, this is the multifunctional water-proofing agent that a kind of water-repellancy, ventilation property, weather resistance, use popularity all are better than other series products.
