Embodiment
The hydrophobic modifier of a kind of building material surface of the present invention, this hydrophobic modifier is grease-inorganic crosslinking type hydrophobizing agent, component comprises: the sewer oil of 60 ~ 100 weight parts, the emulsifying agent of 0 ~ 6 weight part, the inorganic crosslinking agent of 10 ~ 30 weight parts, in described sewer oil, the content of higher fatty acid ester is greater than 50%.
Described inorganic crosslinking agent is the sodium silicate solution of 50≤° B é≤60.
Described emulsifying agent is sodium stearate, sodium lauryl sulphate or linear alkylbenzene sulphonic acid.
In a method for hydrophobic modifier prepared by building material surface, comprise the steps:
(1) sewer oil is heated to 50 ~ 80 DEG C, crosses and filter impurity, then at 100 DEG C distillation and concentration to constant weight;
(2) concentrated solution prepared by step 1 and be cooled to 30 ~ 40 DEG C, add after emulsifier for mixing to sewer oil disperses completely, add inorganic crosslinking agent, warming while stirring to 60 ~ 80 DEG C, and then constant temperature stirs 60s ~ 5min;
(3) mixed solution step 2 obtained leaves standstill 10 ~ 15min at 50 ~ 60 DEG C of constant temperature, then applies or is sprayed on building material surface, naturally dry.
In above-mentioned preparation method, its from sewer oil to grease-the total formula of reacting condition process of inorganic crosslinking type hydrophobizing agent is:
Wherein R base can be group of the same race also can be group not of the same race.
Multiple reaction process is comprised in this net reaction:
A) sewer oil main component---higher fatty acid ester hydrolysis reacts:
ROOCH
2CHOORCH
2OOR+H
2O→ROOH+HOCH
2CHOHCH
2OH
There is hydrolysis reaction in higher fatty acid ester, become higher fatty acid and glycerine in the weakly alkaline environment of water glass.
B) water glass can occur to ionize hydrolysis reaction, presents weakly alkaline:
Na
2SiO
3+H
2O→NaOH+H
2SiO
3
C) there is saponification reaction in partial higher fatty acid:
ROOH+NaOH→ROONa+H
2O
D) water glass hydrolytie polycondensation, carries out sol-gel process:
H
2SiO
3+H
2O→Si(OH)
4
n Si(OH)
4→n SiO
2+n H
2O
Water glass can accelerate to be dehydrated into silicon-dioxide spatial network under the catalysis of higher fatty acid ester, large-scale R base group and higher fatty acid sodium can be filled in the space of network of silica segmentation and go, free hydroxyl group is wherein extruded spatial network really, and the steric effect of Long carbon chain can repel again the attachment of hydroxyl at network of silica simultaneously.Network of silica also can be attached to inorganic building material surface firmly, becomes R base group and " tack coat " between higher fatty acid sodium and inorganic building material.
E) partial higher fatty acid can close with the free silica bond of network of silica, be attached directly to network originally with it:
RO-OH+-Si-O-(SiO
2)n→RO-Si-O-(SiO
2)n+-OH
Because the impact of higher fatty acid Long carbon chain, very weak in the electronic cloud deflection of carbonyl and hydroxylic moiety, so there will be the result of hydroxy seco, then free silica bond is closed with part.
In above-mentioned preparation method, whole reaction process signal as shown in Figure 1.When sewer oil directly joins in sodium silicate solution, because organic liquid phase is incompatible with inorganic liquid phase, so liquid presents suspension liquid, sewer oil is reunited together in water glass, there is (Fig. 1-1) with the situation of oil group.After adding tensio-active agent, under emulsifying effect, keech is broken up into the oil droplet of nanometer to micron level, so can be evenly distributed to (Fig. 1-2) in whole sodium silicate solution under stirring.Along with the temperature of whole liquid-phase system raises, losing efficacy appears in the modifying function being attached to the surfactant molecule on oil droplet top layer, oil droplet directly contacts with water glass molecule and reacts, at temperature and weakly alkaline environment effect, there is hydrolysis in higher fatty acid ester, with silicon-oxy tetrahedron cluster generation substitution reaction in blended liquid phase system, macromole R base replacement-OH is combined with Si and forms organic water glass group (Fig. 1-3).
After grease-inorganic crosslinking type hydrophobizing agent is coated in matrix surface, because water glass is a kind of typical inorganic crosslinking agent, be easy under certain condition form firmly mineral membrane at mineral surfaces hydrolytie polycondensation, the macromole R base group combined with water glass group then forms hydrophobic layer (Fig. 1-4) at water glass film surface alignment, the Stability Analysis of Structures formed is very stable, not easily be destroyed under normal temperature conditions, so the time length of hydrophobic effect is just long.
Below in conjunction with specific embodiment, set forth the present invention further.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
