Description
Technical field
The present invention relates to a kind of water-repellent paints, more particularly, to a kind of VAE water-repellent paints and its construction method.
Background technology
Building water-proof paint is a kind of important waterproof material currently on the market, by its film forming binder can be divided into pitch class,
The multiple types such as high-polymer modified pitch class, synthesis high score subclass, inorganic cement class, polymer cement class.Wherein, high score is synthesized
Subclass can be divided into two class of solvent type and emulsion type again, and emulsion type single-component waterproof coating material is because its is easy to operate, can be more
The links such as construct on moist screed-coat, and produce, store, transporting, constructing are safer, obtained more widely answering
With.
VAE water-repellent paints are a kind of current common macromolecule flexible waterproof coatings, mainly with aqueous ethyl vinyl acetate second
Alkene copolymer emulsion (VAE) is base-material, is equipped with a certain amount of auxiliary agent and filler is blended through special process.Existing VAE waterproofs
Coating has the following disadvantages：(1) and the basal plane poor compatibility of concrete or mortar, adhesion strength are low；(2) endurance quality and resistance to old
Change poor performance；(3) it is also easy to produce pinprick stomata in construction, it is necessary to carry out construction in layer, cover up and down, reduce construction efficiency.
For example, the Chinese patent of application publication number CN104610876 A discloses a kind of silicon rubber waterproof coating, by following
Components by weight percent raw material forms：20-30 parts of silicon rubber lotion, 5-10 parts of VAE lotions, 20-30 parts of deionized water, nanosized SiO_2 1-5
Part, 20-30 parts of white carbon, 1-2 parts of turpentine oil, 0.1-0.5 parts of neopelex, 2-6 parts of cenosphere, levelling agent
0.1-1 parts of RM-2020,1-2 parts of coupling agent, 1-2 parts of antifoaming agent, 1-2 parts of dispersant, 0.1-0.5 parts of mould inhibitor, bentonite 1-5
Part.The silicon rubber waterproof coating has the following defects：(1) silicon rubber waterproof coating is macromolecule flexible waterproof coating, and mixed
The basal plane poor compatibility of solidifying soil or mortar, adhesion strength are low；(2) contain bentonite, bentonite companion deposits organic matter and form and aspect are deeper
Other dirts, lead to coating hue difference；(3) it is also easy to produce pin hole in construction, influences waterproof effect；(4) after construction
The easy sagging of wet film, causes in uneven thickness, influences waterproof effect；(5) nanosized SiO_2 is not easy evenly dispersed, is easily reunited.
Invention content
The present invention is that it is reasonable to provide a kind of formula in order to solve the above problem present in the water-repellent paint of the prior art
Science, good with the basal plane compatibility of concrete or mortar, adhesion strength is high, and workability, endurance quality and ageing-resistant performance are good,
It can prevent the VAE water-repellent paints of particulate material sedimentation and wet film sagging phenomenon.
The invention also discloses a kind of VAE water-repellent paints construction methods, and step is simple, and operability is strong, and construction efficiency is high.
To achieve the goals above, the present invention uses following technical scheme：
A kind of VAE water-repellent paints of the present invention, are grouped as by the group of following parts by weight：40~45 parts of VAE lotions, 15~20
Part acrylic emulsion, 5~10 parts without soap organosilicon rubber emulsion, 3~8 parts of modified Nano rectorite slurries, 0.2~0.4 part of alkane
Base phenol polyethenoxy ether, 1~1.5 part of Sodium Polyacrylate, 0.5~1 part of ethylene glycol monobutyl ether, 1~1.5 part of lithium magnesium silicate, 1~2

1 part of Antisepticize and mildew preventive, 15~20 parts of water, appropriate pH regulators.In the present invention in addition to modified Nano rectorite slurry is self-control,
Remaining component is commercial product；The present invention improves and optimizates the formula of VAE water-repellent paints, and water-repellent paint is most importantly
Base-material is selected, the present invention in VAE lotions, acrylic emulsion and without three kinds of polymer emulsions of soap organosilicon rubber emulsion into
Row, which compounds, is used as base-material, and VAE emulsion content highests in base-material, VAE lotions have excellent compatibility, and can guarantee the soft of coating
Toughness and elasticity, acrylic emulsion can reduce the surface tension of coating of the present invention, improve the present invention to concrete or mortar basal plane
Wettability, to be conducive to improve the adhesion strength of the present invention and concrete or mortar basal plane, no soap organosilicon rubber emulsion
With very excellent high and low temperature resistance, the chemical bond of (or radiation exposure) molecule is not broken under high temperature, does not decompose, when low temperature
Still there is very high extension property, either chemical property or physical mechanical property, variation with temperature all very littles, therefore be somebody's turn to do
Lotion can use within the scope of a very wide temperature, be in addition not easy by ultraviolet light and ozone point without soap organosilicon rubber emulsion
Solution, but cost is higher, it is therefore desirable to addition of the control without soap organosilicon rubber emulsion considers, in the present invention with 40~
45 parts of VAE lotions, 15~20 parts of acrylic emulsions, 5~10 parts without soap organosilicon rubber emulsion as base-material, in control cost
On the basis of, farthest improve adhesion strength, elasticity, weatherability and resistance to ag(e)ing of the present invention；It also added in the present invention
Modified Nano rectorite slurry, the modified Nano rectorite in the slurry are uniformly dispersed, are not easy to reunite, and have good dispersion
Property, suspension and levelability so that present invention film forming is smooth, and pin hole is not likely to produce after film forming, in addition, modified Nano rectorite has
Standby good UV blocking capability can further increase the weatherability of the present invention, meanwhile, modified Nano rectorite has nanometer
The quantum effect of material can greatly improve the adhesive force of the present invention, it is most important that, modified Nano rectorite has the ratio of bigger
Surface area, which increases with certain polar groups in polymer emulsion in the present invention such as hydroxyl, epoxy group and alkoxy etc.
Absorption and crosslinked action, make the organic matter in modified Nano rectorite and coating be connected to each other to form network structure, make system
Viscosity and consistency increase, and play the settlement action for preventing or slowing down particulate matter in coating, but should strictly control the tired support of modified Nano
Otherwise the dosage of soil paste material will produce false thickening behavior；Levelability and thixotropic balance are also very crucial in the present invention
Technology, the present invention be make every effort to thixotropy fully take into account levelability, accomplish optimum balance, with obtain ideal rheological property with
Construction effect selects 0.5~1 part of ethylene glycol monobutyl ether as levelling agent, the silicic acid for selecting 1~1.5 part of purity high thixotropic good
