Description
Technical field
The present invention relates to paint field, particularly relate to a kind of weather-resistant emulsion paint used on exposed-wall.
Background technology
Emulsion paint is being commonly called as of latex coating, is born in the next period in nineteen seventies, is take acrylate copolymer emulsion as a large class synthetic resin emulsion coating of representative.Emulsion paint is water-dispersible paint, and it take synthetic resin emulsion as base-material, and filler adds the coating that various auxiliary agent is refined after grinding distribution.Emulsion paint has possessed the many merits different from conventional wall coating materials, and as being easy to brushing, drying is rapid, paint film is water-fast, scrub resistance is good.In China, people are base-material synthetic resin emulsion traditionally, take water as dispersion medium, add pigment, filler (also known as pigment extender) and auxiliary agent, through the coating that certain technological process is made, be called emulsion paint, be also latex coating.
Emulsion paint has inner, external wall to use respectively.The major function of exterior wall latex paint is decoration and architecture protection object plane, makes buildings appearance neat and artistic, thus reaches the object of beautifying urban environment, can play the effect of architecture protection beyond the region of objective existence wall simultaneously, extend its work-ing life.The emulsion paint applied environment used as exterior coating is relatively severe, and ultraviolet, heat energy, microorganism, water, pollutants in air etc. can cause the aging of polymkeric substance in coating, cause polymer degradation, destroy coating; Especially can make under uviolizing that some pigment fade, yellowing, efflorescence, its weather resistance is unsatisfactory; When having some emulsion paints to be coated in engineering, only just there is discolouration phenomena in some months.Therefore, emulsion paint also will have the performance of ultraviolet radiation resisting, can nondiscoloration under sunlight irradiates for a long time.
At present, water tolerance and the water-repellancy of commercially available most of exterior wall latex paint product are poor, and tensile strength is low, and sticking power is general.Because it is not water-fast, non-watertight, entirety will peel off at its paint film after rain drop erosion, or cause cracking due to the difference of water ratio or peel off, rainwater just infiltrates metope, corrosion metope; Simultaneously because the pollution of the dust in an atmosphere of being easily subject to after construction suspending, oily matter makes the coating surface of exterior wall latex paint be polluted.Therefore, along with the requirement of Modern City Building to high durable exterior wall latex paint strengthens gradually, be badly in need of a kind of exterior wall latex paint that can meet weathering resistance and low cost needs of exploitation.
Summary of the invention
