Abstract

The present invention belongs to the preparation of chemical building material. The prior emulsion type styrene-butadiene-styrene waterproof coating must use asphalt as a solubilizer, and the asphalt absorbs light and heat, is cold, brittle and hot flowing, is not aging-resistant, is malodorous and pollutes the environment. The invention provides a non-asphalt emulsion type styrene-butadiene-styrene waterproof coating, which is prepared by replacing asphalt with rosin and turpentine derivatives, and adding a proper amount of modifier, plasticizer and emulsifier. Firstly, water-in-oil emulsion is prepared, and then a large amount of hot water is added to make the water-in-oil emulsion type waterproof coating reverse to oil-in-water emulsion type waterproof coating.

Description

A kind of non-asphalt emulsion water-proof coating and method for making
The invention belongs to material of construction, in particular for waterproof, leak stopping and the sealing between the various building slabs of buildings.
Construction waterproof coating has four big classes by the formulation classification: solvent-borne type, emulsion-type, biliquid response type and hot-melting type, wherein emulsion-type is to be solvent with water, have and do not fire, nontoxic, superiority such as pollution-free and inexpensive, therefore this class waterproof paint is very welcome, but on the market emulsion-type coating such as butylbenzene, neoprene, emulsion coatingss such as vinylformic acid all are to add some modified emulsion again with ready-made latex, filler and making, general solid content 40-50%, these coating all have visco-elasticity and water resistance preferably, price is also cheap, but, can only make thin coating and influence mechanical property and weather resistance because plasticity is not enough.And styrene-butadiene-styrene rubber is SBS rubber, has excellent elasticity and plasticity and winter hardiness, lower in the solution medium viscosity, can prepare highly filled thick coating, but SBS to be made the industrialization emulsion paint, also very difficult, 1994 the 1st phase P-17 of Chinese architecture water-proof material and the 1st phase of nineteen ninety-five P-19 report Chinese Suzhou, and SBS is dissolved in pitch under 190-200 ℃ to become less even this of viscosity be to use the emulsification of mineral emulsifying agent again, this coating is to adopt pitch as solubilizing agent, and because the easy emulsification of pitch also makes SBS emulsification smooth, pitch itself has water-fast, bullet is moulded, adhesiveproperties and inexpensive, therefore this coating uses very general at present, but well-known, pitch blackness, extinction heat absorption, the lighter roofing of roofing temperature is raise 30 ℃, it is cold short, heat is dropped down, not ageing-resistant, in heat, light, hardening under the oxygen effect, become fragile, cracking comes off and causes waterproof effect to descend, and pitch also contains harmful material, and foul smelling, increase the pollution of environment.
The purpose of this invention is to provide a kind of non-asphalt emulsion waterproof paint.This coating is white or light, nontoxic, odorless, have high elastoplasticity.
Non-asphalt emulsion water-proof coating provided by the present invention, be to adopt SBS rubber (styrene-butadiene-styrene rubber) (792 types or 802 types) to be material of main part, replace pitch as tackifier with modified rosin resin or turps derivative, use neoprene latex latex, acrylic latex, the polyethylene vinyl acetate emulsion, Vinyl Acetate Copolymer-ACRYLIC EMULSION, polypropylene, polyisobutene, isoprene-isobutylene rubber, terpolymer EP rubber is as properties-correcting agent, give coating elasticity, bonding force, ageing resistance and thermostability, used softening agent is a Dormant oils, chlorine is cured, phthalic ester, the 12-18 carbon fatty acid, Viscotrol C, plam oil, Oleum Cocois, oleum lini, epoxidised soybean oil, solvent are acetone, toluene, ethyl acetate.The used nonionic emulsifying agent of the present invention is polyoxyethylene aliphatic alcohol ether and sulfonate thereof, polyoxyethylene Fatty Alcohol(C12-C14 and C12-C18), polyoxyethylene alkane phenolic ether, polyoxyethylene sorbitol fatty acid ester, and used anionic emulsifier is Succinic Acid fat sodium sulfonate, 12-18 alkyl (aryl) sodium sulfonate, Succinic Acid polyoxyethylene Fatty Alcohol(C12-C14 and C12-C18) (phenol) ether sulfonic acid sodium.Solvent is acetone, toluene, ethyl acetate.Waterproof paint prescription provided by the present invention contains following composition (parts by weight):

Solid content 50-60%
Emulsion-type waterproof paint provided by the present invention, the waterproofing and leakage-stopping that is used for buildings is compared with emulsion paint of the prior art, have look shallow (or white), nontoxic odorless, high elastoplasticity, high strength and excellent low temperature flexibility and ageing-resistant performance, construction process and storage period safety, free from environmental pollution, add light reflecting material at coating surface and have also that reflective, the anti-width of cloth is penetrated, the multiple function of heat insulation, heat radiation, and cost only is the 50-60% of existing emulsion-type waterproof paint.
Emulsion-type waterproof paint measurement result (comparing) with existing waterproof paint
The manufacture method of non-asphalt emulsion water-proof coating provided by the present invention is as follows: with styrene-butadiene-styrene rubber, the rosin turpentine derivative is misciblely made A solution in solvent in 80-100 ℃, splash into then by emulsifying agent, water, in the seed emulsion of a small amount of A solution composition, generate water in oil emulsion, adding the strong reverse of a large amount of hot water again is oil-in-water stable emulsion, vacuumize the recovery solvent, add filler then, pigment, the room temperature that stirs discharging, if the properties-correcting agent emulsion-type then can mix with it behind this paint emulsification, add filler again, pigment etc., it is first emulsification post-modification, if used properties-correcting agent is solid state then be cut into particle and SBS with miscible in A solution reemulsification, emulsification after the promptly first modification.
