Description
Technical field
3. the invention belongs to water-repellent paint technical field, and in particular to a kind of polymer cement waterproof paint.
Background technology
5. polymer cement waterproof paint is using acrylic polymer emulsion and cement as primary raw material, add other additional
Double-component aqueous building water-proof paint made from agent.Product is divided into I type and II type, and I type is mainly used in non-length based on polymer
Constructure waterproofing engineering under phase Soaking environment；II type based on cement, prevent by the building being mainly used under long-term Soaking environment
Hydraulic Projects.Extensibility, the water proofing property of this existing polymer coating film of coating, also have the aquosity gel strength of materials it is high, it is easy with it is moist
The advantages of basic unit bonds.But the problems such as still suffering from not ideal enough mechanical property, impervious, poor durability at present, seriously limits
The promotion and application of such coating.At present, the research of polymer cement waterproof paint is focused primarily on acrylic polymer
In the chemical modification of emulsion, the research for water-repellent paint serves certain effect, but due to acrylic polymer
For organic matter, for the development of long-standing problem polymer cement waterproof paint coating durability and relatively low mechanical strength the problems such as make
With limited.
Existing polymer cement waterproof paint is conventional acrylic emulsion and the coating based on cement at present simultaneously
Be simply mixed, the cured film formed is easily swelled again by water, can not produce waterproof layer truly, thus waterproof imitate
Fruit is poor, fastness is low.
The content of the invention
The technical problems to be solved by the invention：For current polymer cement waterproof paint be conventional acrylic emulsion and with
Coating based on cement is simply mixed, and the cured film formed is easily swelled again by water, and so as to cause, waterproof effect is poor, fastness

（2）By distilled water, ETHYL CYANOACRYLATE, methacrylate, methylvinyldichlorosilane, polyoxyethylene carboxylate,
Empgen BB is put into reactor, is stirred, and is protected using nitrogen, and is warming up to 70~75 DEG C, is added into container
Enter acrylic acid, mix, add 70~80% ammonium persulfate of ammonium persulfate gross mass, insulation；
（3）Wait after the completion of being incubated, add maleic anhydride, lewis acid, stir, 80~95 DEG C are warming up to, by remaining over cure
Sour ammonium is added in reactor, is reacted；
（4）After the completion of reaction, cool down, add butanol, stir, collect reactant mixture, filtering, collect filtrate, use
Sodium hydroxide solution adjusts filtrate pH to neutrality, remembers modified acrylate emulsion.
The coalescents are any one in propylene glycol methyl ether acetate, alcohol ester 12.
The dispersant is any one in stearmide, OPE.
The water reducer is polycarboxylate water-reducer.
Compared with other method, advantageous effects are the present invention：
Present invention Material synthesis acrylic acid ester emulsion based on ETHYL CYANOACRYLATE, methacrylate etc., in building-up process
In, it is modified using organic silicon monomer methylvinyldichlorosilane, silicon oxygen bond is introduced, adds the knot between cement
It is right, the performance and firmness of film are improved, while in the presence of lewis acid, unsaturated bond is introduced using maleic anhydride,
The active group of emulsion is added, adds the effect with calcium ion, further increases water resistance, also improves the photosensitive of emulsion
Performance, compounded with butanol, improve the mobility of film early stage, and expendable performance is calcined using kyanite, to water
Pore-creating is carried out inside mud, adds the contact performance with emulsion, while emulsion is compounded with o-cresol formaldehyde epoxy resin again, is increased
The performance of coating self-curing film forming is added, it is therefore prevented that cured film is easily by the generation of water Swelling again.
