Description
Technical field
The present invention relates to the technical field of material of construction, refer to a kind of enclosure coating and preparation method thereof especially.
Background technology
The many merits such as cement works thing is low with its cost, fire resistance good, it is simple to make and practical, suddenly become the primary product of current building trade, greatly meet modern people and produce and growing demand of living.From cement wall surface, cement post to enclosure etc., cement building product miscellaneous constantly emerges in large numbers in face of us.Enclosure is also known as cement artistic fence, Cement guard bar, cement railing, and along with the continuous propelling of new rural village and new town construction process, enclosure makes our production and the change of living environment generation essence with the speed of making rapid progress.Various places government in succession put into effect demolish walls reveal the green, the environmental reconstruction policies such as scape of ventilating, prohibite and build solid enclosure wall by laying bricks or stones, traditional enclosure wall must replace by enclosure.
Existing enclosure is generally fitted up at its surface spraying coating for wall surface, thus reach handsome in appearance, the lines flow smoothly and coloury object.Because enclosure is subject to solar radiation for a long time, particularly in summer, temperature obviously raises; In addition, Sometimes When It Rains, often endure again the impact of rainwater to the fullest extent; Existing coating for wall surface anti-uv-ray is poor, not ageing-resistant, makes existing enclosure occur the phenomenon such as decortication after exposing to the weather, and has a strong impact on its result of use and attractive in appearance.
Summary of the invention
The present invention proposes a kind of enclosure coating and preparation method thereof, solves enclosure coating anti-uv-ray difference and easily aging problem in prior art.
A kind of enclosure coating of the present invention, its technical scheme is achieved in that the raw material comprising following weight part: ACRYLIC EMULSION 35-50 part, film coalescence aid 1-5 part, dispersion agent and wetting agent 1-2 part, color stuffing 20-40 part, deionized water 10-20 part, anti-aging auxiliary agent 3-5 part, flow agent 1-2 part, thickening material 1-2 part.
The present invention forms base-material with ACRYLIC EMULSION under the effect of film coalescence aid and thickening material, by color stuffing, it is carried out to the adjustment of color and granularity, and make color stuffing, oil phase and aqueous phase fully disperse and mix under the effect of dispersion agent and wetting agent, deionized water and flow agent, thus form homogeneous coating.Under the synergy of ACRYLIC EMULSION and anti-aging auxiliary agent, make coating have excellent outdoor weatherability, after a procedure, ageing-resistant performance and the anti-ultraviolet property on its surface increase substantially this coating, coatingsurface brightness increases, and improves the overall appearance performance of cement works thing.
As the preferred embodiment of one, the raw material that described ACRYLIC EMULSION comprises following weight percent is made: vinylformic acid 40-45%, butyl acrylate 40-45%, deionized water 5-10%, emulsifying agent 3-5%, acrylamide 1-3%, organosilane monomer 1-3%.ACRYLIC EMULSION of the present invention is on the basis of traditional pure acrylic latex, add acrylamide and organosilane monomer, the weather resistance of ACRYLIC EMULSION is further enhanced, and improve its waterproof, contaminated resistance, the glossiness of coating is improved, protect look gloss retention strong, can the growth of mould fungus inhibition.
As the preferred embodiment of one, described anti-aging auxiliary agent is substituted acrylate.Substituted acrylate antiaging agent is cheap and easy to get, and this antiaging agent is also acrylic acid derivative, and it can act synergistically better with ACRYLIC EMULSION, fully increases the ageing resistance of coating.
As the preferred embodiment of one, in described color stuffing, pigment is inorganic oxide iron pigment, and described inorganic oxide iron pigment is the one in red iron oxide, iron oxide yellow and iron oxide black.Inorganic oxide iron pigment has very high chemical stability, and fast light alkali resistance is good, energy strong absorption ultraviolet, and effectively protective cover base-material and capped article are from ultraviolet destruction; And its solvent resistant, water-fast, chemical resistance good.
As the preferred embodiment of one, in described color stuffing, filler is the one in coarse whiting, talcum powder or kaolin.The particle shape of different fillers is not identical, and the talcum powder with platy particle can improve the globality of film, thus also favourable to water tolerance, alkali resistance etc.; There is the coarse whiting of round particle, when thickness collocation uses, its filling effect can be given full play to; Kaolin also has the effect to film delustring.
