CN1162481C - Water-proof decorative paint containing nano components - Google Patents

Abstract

The present invention relates to waterproof decorative paint containing nanometer components, which is compounded from water, a film forming agent and an auxiliary agent. The paint contains 10 to 20% of nanometer materials. The paint has good comprehensive performance, and especially has excellent waterproof performance for concrete and cement mortar. The paint can be widely used for the engineering of water prevention, seepage prevention and moisture prevention of new and old roof surfaces, exterior wall surfaces, toilets, underground rooms, etc., and for the decorative engineering of interior walls and exterior walls.

Description

A kind of water-proof decorative paint that contains nano components

One, technical field

The present invention relates to a kind of architectural decoration coating material, specifically a kind of water-proof decorative paint that contains nano components.

Two, background technology

At present, domestic construction market, the maintenance cost that the whole nation is used for buildings leakage, infiltration every year is up to billions of units, even high worker's buildings then also has 45～60% to exist the difficult situation that high worker promptly will keep in repair.The top pierced wall oozes the direct life-span that influences buildings, and in addition, not only cause financial loss, and bring endless worry and helpless to the human consumer, even the threat to life property safety.

Building waterproof uses pitch, tar felt at first, uses ointment, resin, rubber etc. afterwards, but all unsatisfactory.There is water base high molecular coating to come out in recent years, have that cost is low, easy construction, advantage such as pollution-free, overcome that the conventional waterproof material is easily aging, the life-span is short, meet cold be full of cracks, meet hot-fluid drops down and drawbacks such as tone is single, but its low-temperature flexibility, unit elongation, tensile strength are not as rubber type of material.For coating, whether easily its quality height also is subjected to such as peeling, peels off, goes mouldy, the restriction of pollution, anti-marquis, other performances such as anti-aging except that water resistance.Therefore the over-all properties that further improves coating is one of direction of current development new coating.

Coating generally is made of nonvolatile filmogen (disperse phase) and evaporable thinner (dispersion medium), filmogen has main film forming substance such as resin, organic polymer emulsion etc., film forming subsidiary material matter comprises filler and pigment, also has auxiliary film forming matter, rising of wherein having promotes dispersion, homogeneous, stabilization such as dispersion agent, wetting agent, emulsifying agent etc., and the film to forming that has has modifying function such as toughner, anti, mould inhibitor, antiaging agent, prevents ultraviolet agent etc.In some occasion, the title main film forming substance is a membrane-forming agent, and film forming subsidiary material matter and auxiliary film forming matter are referred to as auxiliary agent.

Three, summary of the invention

The objective of the invention is to provides a kind of good comprehensive properties high-quality decorative paint for market.Its technical scheme is to mix nano material to give modification on the basis of water base high molecular coating, has obtained gratifying effect.The weight percent of each component is as follows:

Membrane-forming agent 45～50%

Filler 10～20%

Pigment 5～8%

Auxiliary agent 1.5～3%

Water surplus.

Described membrane-forming agent is one or more mixed emulsions in polyacrylate dispersion or benzene emulsion or the polyvinyl acetate emulsion,

Described filler is that at least a nano material or this nano material that is selected from nano rare earth, nano-calcium carbonate, nano silicon oxide mixed with bentonitic,

That described pigment is selected from is nanometer iron oxide red, nano-titanium oxide, iron oxide yellow, titanium dioxide, zinc sulfide white, phthalocyanine blue or phthalocyanine green etc.Wherein nanometer iron oxide red and nano-titanium oxide has the effect of Nano filling concurrently.

Described auxiliary agent has two kinds, and a kind of has been the F-4 or the OP-10 of dissemination, and another kind has been the dibutylester or the sodium bicarbonate of toughening effect.

Nano filling is different from common coarse grained mineral filler, because characteristics such as the serious coordination deficiency of its huge specific surface area and surface, there are many active centre, can play the strong bonding effect with membrane-forming agent, make the toughness of the film of formation, particularly low-temperature flexibility and tensile strength, sticking power, unit elongation, wear resistance, scrubbing resistance, over-all properties such as anti-aging all obtain bigger raising; Especially this coating forms vitreous state or ion gel attitude at concrete or sand-cement slurry surface, nano particle forms new silicate complex body with the cement reaction among can infiltrating fine fisssure or slit, so waterproof effect is splendid, can be widely used in the decorative engineering of waterproof, antiseepage, moistureproof engineering and interior exterior walls thereof such as new old roof, wall face, toilet, vault.
