Abstract
It is mainly made up by using vinyl acetate, polyvinyl alcohol, titanium pigment, plastic cement solution, tributyl ester, formaldehyde and water according to a certain mixing proportion through the procedures of repeatedly mixng, stirring, filtering and standing still. Said product possesses the advantages of resisting ageing, strong adhesive force, good cohesion, long service life, and low cost.
Description
The present invention relates to a kind of material of construction, particularly a kind of water-proof emulsion for roof.
High-rise roof all is the plane layer top, so antiseep is the hard nut to crack that people do not have fine solution always.At present, high-rise roof is to adopt water proofing asphalt, ointment or PVC coiled material to be layered on the top layer roofing to make WATER REPELLENT mostly on the plane in construction sector, but to use this class material that a common fault is all arranged be exactly product deck expose to the sun and rain easily aging, poor adhesive force, waterproof effect is bad, work-ing life is short, moreover the construction trouble, price is also more expensive.
Purpose of the present invention will provide exactly that a kind of anti-aging, strong adhesion, cementability are good, good water-proof effect and lasting, the simple water-proof emulsion for roof of constructing.
The present invention realizes like this.The composition of raw materials of water-proof emulsion for roof is: acetic acid second is rare 32～37%, and polyvinyl alcohol 17～22% is eliminated white powder 17～22%, plastic cement liquid 13～18%, and tri butyl ester 5%, formaldehyde 1%, all the other are water.
Compound method of the present invention is: (1) puts in solvent barrel (pond) at first that acetic acid second is rare, tri butyl ester, plastic cement liquid mix and stir that to make mixed solvent standby; (2) get an amount of mixed solvent from solvent barrel (pond) and put into mother vat (pond), in mother vat (pond), add an amount of polyvinyl alcohol again, eliminate white powder and water dissolution and stir after a few hours and make female pond; (3) get an amount of mixed solvent in the solvent barrel (pond) and put into dilution bucket (pond), and add that an amount of acetic acid second is rare, formaldehyde is mixed with diluent; (4) getting an amount of mother liquor and diluent puts into base-material bucket (pond) and stirs and to make base-material liquid and left standstill behind screen filtration tens of hours; (5) add once more in the base-material liquid after leaving standstill that an amount of acetic acid second is rare, plastic cement liquid, eliminate white powder, the tri butyl ester high-speed stirring obtained finished product about 2 hours.
Resistance to deterioration of the present invention is strong, does not trickle below high temperature+80 ℃, do not chap more than the low temperature-40 ℃, and strong adhesion, good, the long service life, nonpoisonous and tasteless of cementability, and construction is simple, inexpensive.Can be widely used as leakproofing materials such as roof, ground, body of wall, pond, its appearance provides a kind of ideal water-proof emulsion for roof for people.
Embodiment is described below
Composition of raw materials is: acetic acid second is rare 35%, polyvinyl alcohol 20%, eliminate white powder 20%, plastic cement liquid 15%, tri butyl ester 5%, formaldehyde 1%, water 4%.
Compound method is: (1) gets rare 15 kilograms of acetic acid second, 3 kilograms of tri butyl esters, plastic cement liquid is put into solvent barrel for 8 kilograms and is stirred, it is standby to make mixed solvent, (2) get 13 kilograms of mixed solvents from solvent barrel and put into mother vat, add 20 kilograms of polyvinyl alcohols again, eliminating 4 kilograms of dissolvings of 10 kilograms in white powder and water stirs after 2 hours and makes mother liquor, (3) get 13 kilograms of mixed solvents from solvent barrel and put into the dilution bucket, and add rare 10 kilograms of acetic acid second, formaldehyde is mixed with diluent for 1 kilogram, (4) get 47 kilograms in mother liquor, diluent is put into the stirring of base-material bucket for 23 kilograms and is made base-material, and left standstill 12 hours through screen filtration, (5) add rare 10 kilograms of acetic acid second once more in the last base-material (71 kilograms) after filtration, 7 kilograms of plastic cement liquid, eliminate 10 kilograms in white powder, 2 kilograms of tri butyl esters, and high-speed stirring 2 hours, obtain the double centner finished product, can gets final product.
Claims (2)
