Its advantages are high water-proofing effect and fast filming.
Description
Technical field
The present invention relates to be used for the manufacture method of the solvent complex type organic silicon water-proofing liquid of porous substrate WATER REPELLENT.
Background technology
Existing waterproofing agent of organosilicon has aq. type, paste type, emulsion-type and powdery type.Base material will add that another type water-resisting agent gets on again and be very difficult and reach to cover and be not coated with effect that its easy layering can not be adsorbed onto the top layer, and dry slow that effect is bad after using a kind of waterproofing agent of organosilicon.Along with the raising of environmental requirement, can not contain in the solvent of finishing material healthy toxic and environment is had a material of pollution.For ease of construction, require to select different type of solvent, to reach the requirement of different time of drying in the construction according to the variation of solvent in temperature.
Summary of the invention
The objective of the invention is to problem, a kind of manufacture method of solvent complex type organic silicon water-proofing liquid is provided, adopt the solvent that meets environmental protection and health requirements, produce the organic silicon water-proofing liquid that can adapt to multiple construction substrate and engineering time at the prior art existence.
The present invention is the material that will be easy to get, and two sense organopolysiloxane and organosilicon cross-linking agent, coupling agent adopt reasonable proportioning, the composite method that gets, and solidify the strict novel product method of controlling film formation time and making when construction with catalyzer.
The manufacture method of solvent complex type organic silicon water-proofing liquid of the present invention may further comprise the steps:
(1) two functional group's organo-siloxane and solvent stirred in the mass parts adding agitator by 1: 2, fed N
2, after 20-40 minute, add coupling agent, remix 20-40 minute; At N
2Keep adding organosilicon cross-linking agent down, the mass ratio of two sense organosilicon polysiloxanes and linking agent, coupling agent is 15～20: 60～70: 15～20;
(2) stir the solvent that adding is equivalent to step (1) mixture 6-10 part quality after 0.5-1 hour, stirred 0.5-1 hour;
Described two sense organo-siloxanes are straight chain shape polymerization organosilicon oxygen alkane, and its link units is R
1O (R
2SiO)
nR
1Wherein R is methyl, ethyl or propyl group, R
1Be hydrogen or alkyl, n represents chain number; Molar weight is 1 * 10
4～4 * 10
4Linking agent is RSiX
3, R is alkyl or aryl or group with reactive behavior; The group of X for reacting with water; Coupling agent is KH550, A151 or A171.
Solvent is selected decide according to base material, varsol for example, and varsol is not only nontoxic, have no side effect, and can also match different hydrocarbons solvent and composition thereof, controls its set time, forms fast dried, slow curing or moderate speed's drying when using on base material.Solvent adding amount is good with 8 times.
Use construction to add catalyst reaction polymerizing curable film forming again, during curing catalyzer be in the mix products solid content part 2～3%, its reactant infiltration is inconsistent according to the different substrate materials degree of depth, generally at 1～5mm.
This waterproof liquid can permeate base material, and porous substrate can permeate 6～7mm, microporous substrate is generally arranged except that metal object, all can reach the depth of penetration about 1～3mm.That film formation time divides is fast, in, slow three classes.Fast class is 2 hours, class is 6 hours slowly, is cured as good with 24 hours.This type of product is divided into bi-component package on the packaging.And can overcoating to the base material that was coated with water-resisting agent, good effect is arranged.Solid content is between 5～10%.The catalytic amount that adds when construction is 0.4/1000th～1% of a whole material, is good with 0.5%.Film formation time generally is the catalyzer add-on about 1 hour.The whole prod solid content is 4～8%, with 4.5～5% for well.
The organic silicon water-proofing liquid chain link complexity that makes is dispersive before curing, and solidifying the back is polymkeric substance with two sense organopolysiloxane and trifunctional organo-siloxane.
The present invention compared with prior art has following advantage:
(1) has good weatherability properties, can keep secular waterproof effect after the construction.
(2) can form during liquid-solidization of the waterproof reaction of the present invention preparation is the crosslinked body of waterproof membrane a kind of crossover network class, that certain depth is arranged.
(3) the waterproof liquid of the present invention preparation to be coated with base material with water-resisting agent can repeat to be coated with into, reach double effects, used aq. type or paste no matter be, the substrate surface of powdery water-resisting agent, if the increase water resistance then can repeat spraying with this thing, contain better effect.
