Abstract
A water-proof compound paint is prepared from inorganic components and organic emulsion which may be the emulsion of polyacrylate and ethyl polyacetate, or vinylidene-neoprene emulsion, and features that it can be used to form a layer of protecting film on different organic and inorganic substrate and said protecting film has stable and compact structure, high elasticity, high toughness and high strength and long service life.
Description
The present invention relates to a kind of composite water-proof paint, particularly relate to a kind of waterproof paint that can be directly on the basal plane of multiple organic and inorganic, forms the resilient protection rete of the high-strength longevity of form compact and stable, high-elastic high-ductility.
In current construction industry, urethane is widely used in the waterproofing work as the response type waterproof paint, but because of its outward appearance is a chocolate, the coating tarnish, the decorative appearance performance is not good, longer because of the coating curing time again, strength enhancing is slow, as bi-component reaction-type coating, need accurately weighing cooperation at the construction field (site) during use, can use after stirring, again because of it has certain combustibility and toxicity, this brings inconvenience for storing transportation.
" chlorosulfonated polyethylene " of the U.S. (promptly＜chloro-sulfonated polyethylene rubber coating 〉) some polymer-based flooring is had aggressiveness, influence range of application
" rich sticking FLXIII type " esters of acrylic acid elastic water proofing paint of Britain itself is Dark grey, and requires to use under 25 ℃～35 ℃ dry well-ventilated's situations, also requires during construction to wear gloves and safety glasses, avoids the material contact to cause allergic reaction.
Water-latex type modifying asphalt coating series easily wears out, influences work-ing life and intensity as single organic polymer synthetic materials, adds pitch and is detrimental to health, and contaminate environment brings many difficulties and inconvenience for the construction of waterproofing work.
And for example, Chinese patent application CN1058034A discloses a kind of spray-type floor paint of polyvinyl acetate emulsion, wherein based on polyvinyl acetate emulsion, has added dibutyl phthalate etc. as properties-correcting agent.Although this coating has improved water tolerance on certain program, still there is some defective for waterproof requirement height and wet environment use.
CN85105748A discloses method of preparation of eth-prop emulsion lacquer at room temperature, and its major ingredient has Vinyl Acetate Copolymer acid and the copolymer emulsion of propylene butyl ester and additive and the water that some is commonly used.This emulsion paint can replace existing general paint, and is water miscible.
The purpose of this invention is to provide a kind of nonpoisonous and tasteless pollution-free; all can be directly in the environment of dry or tide temperature (but not having open fire) on the basal plane of multiple organic and inorganic fine and close, high-elastic, the high-ductility of formation, high-strength, long-lived resilient protection rete, also can add various pigment and on basal plane, form colorful decorative waterproof water coating.
The present invention adopts copolymer emulsion and multiple inorganic component combination, make its water-repellancy, intensity, etc. various performances all can reach best synergy.
It is the liquid material of main body that this coating is selected the copolymer emulsion of being made up of polyacrylic ester, polyvinyl acetate (PVA) for use, is based on it and contains a large amount of polar groups, has affinity, embodies the free of contamination environment-friendly advantage of nontoxic odorless simultaneously.
By using caking agent---phthalic acid dibutyl ester, strengthening the cohesive strength of coating, use softening agent the multiple basal plane of organic and inorganic material---tributyl phosphate can reach and strengthen ultimate tension extensibility, distortion adaptability, flame retardant resistance and froth breaking effect.
In inorganic component, based on white cement, wherein Calucium Silicate powder has been filled up the space, magnesium oxide strengthens hardness and flame retardant resistance, siloxy and silicon hydroxyl that the white carbon black surface exists are the hydrophilic functional groups, the easy moisture absorption, is improved electrical insulating property at water insoluble and sour, obviously improve elasticity, high temperature resistant, wear resistance.
Cornstarch, talcum powder, silica powder, weather-proof, ageing-resistant, the resistance to tearing of raising.
But FD-N-S early strength water-reducing agent polarization adsorption, make the white cement particle have the intensive dissemination, thereby reduced the interparticle magnetism of cement, hinder effectively and destroy intergranular cohesion, impel to discharge and coagulate a certain amount of water in the flco, can reduce the mixing water amount greatly, improve Yi Hexing, make that the diameter and the overall porosity of pore structure obviously reduces after the hardening of cement, pore disperses more even, tiny.By postponing the hydrated cementitious thermal spike, avoid cement before obtaining certain intensity because of thermal stress ftractures, so both can strengthen close answering property, improved impermeability again.
Certainly, as various additives, as defoamer, caking agent, water reducer etc.Under the prerequisite that does not influence waterproof paint of the present invention, other various known additives also can be used, and this also falls within the scope of the present invention.Various additives known are known to those skilled in the art.
Therefore, waterproof paint of the present invention includes but are not limited to::

2Thickness: 0.25-0.45mm.
*If coat-thickness is not enough, can adds and be coated with a number of plies layer.
2 processing base level
Basal plane requires necessary smooth, firm, clean, no open fire, ne-leakage, the uneven and first levelling of place, crack palpus, and leakage must be carried out leak stopping earlier and be handled (" water does not leak " of recommending use our company to produce carries out leak stopping), and arc chord angle should be made in the negative and positive angle.
7. 3 prepare burden
Add water if desired, elder generation adds water in the liquid material, add powder while stirring slowly with agitator, stirs afterwards not contain granule (about churning time 5 minutes, preferably not mixing by hand) in material.
The weight proportion of prime coat coating is liquid material: powder: water=10: 7: 14; The weight proportion of lower floor, middle coating intermediate is liquid material: powder: water=10: 7: 0-2; Last coating can add pigment to form color layer, and the weight proportion of color layer coating is liquid material: powder: pigment: water=10: 7: 0.5-1: 0-2.In adding in the water scope of regulation, inclined-plane, end face or facade construction should not add or add less, and the plane construction should be added.
7. 4 apply
Apply with roller or brush,, successively finish according to the order on prime coat → lower floor → nonwoven city → middle level → upper strata according to selected worker's method.A former coating film of the timed interval between each layer is done solid sticking being as the criterion (be under 20 ℃ the open-air condition, not go up people's construction and need 3 hours approximately in temperature, last people constructs approximately need 5 hours).In situ temperature is low, high humidity, ventilation are poor, it is long to do the solid time; Otherwise it is short.For Q5 worker's method, its lower floor, non-woven fabrics and middle level be construction continuously, can not be at interval.Should note following item during coating:
(1) if coating (especially backing material) has precipitation to stir at any time, several down in the stirring of charging basket bottom earlier when dipping in material at every turn, in order to avoid precipitation.
(2) coating will be tried one's best evenly, and local deposits can not be arranged, and every layer of coating must be in accordance with regulations with measuring material, and cutting can not be blocked up or thin excessively;
(3) as if waterproofing layer thickness is not enough at last, can add to be coated with one or more layers.
What should understand is, under the prerequisite of spirit of the present invention, can make various changes and improvement to the present invention, and these changes and improve and also fall into scope of the present invention, and scope of the present invention is limited by following claim.
