Description
Technical field
The present invention relates to waterproof paint field, relate in particular to a kind of II type polymer cement waterproof paint and preparation method thereof.
Background technology
Polymer cement waterproof paint is by rational proportion, compounded a kind of bi-component waterborne building water-proof paint with mineral fillers such as organic liquid material of polyacrylate dispersion or ethene-vinyl acetate copolymer emulsion (being called for short VAE emulsion) etc. and various additives composition and cement, quartz sand and various additives.This material originates from the Japan of the 1950's, and has applied for patent.Within 1991, China starts development, and researches and develops successfully the end of the year 1994.The advantage that the existing cementitious materials intensity of this waterproof paint is high, easy and moist basal plane is bonding, has again the advantage that polymer coating film elasticity is large, water resistance is good concurrently.This material be take water as carrier, has overcome the heavy-polluted shortcoming of organic solvent waterproof paint, its with nontoxic, can wet trade, simple operation and other advantages becomes rapidly the especially favorite of Housing decoration industry of building material industry.
VAE emulsion has advantages of with cement point of application many, therefore the polymer cement waterproof paint that adopts VAE emulsion to prepare has good workability and workability, is easy to construction.In order to adapt to the needs of different construction locations, prepared the polymer cement waterproof paint of different ratios liquid powder ratio.And cement has better water tolerance and weathering resistance with polymer phase ratio, reduce polymer cement ratio, not only can improve to a certain extent water tolerance and the weathering resistance of polymer cement waterproof paint, and there is certain economy.But in actually operating, low polymer cement ratio diminishes the range of choice of emulsion.Reason is to reduce the easy sagging of coating elevation construction after polymer cement ratio; And on irregular basal plane, cloudy external angle position is more prone to cracking phenomena.
Acetic acid mixed ester is the high boiling point environmentally friendly solvent in recent years occurring, this solvent has extremely strong solvability and consistency, and nontoxic smell is good and with low cost, the most important thing is all to mix with water and softening agent.The people's such as Wang Huiming Chinese patent application (publication number: CN 101550309A) relate to a kind of nano-material modified II type polymer cement waterproof paint and preparation method thereof.This patent has been mentioned the phenomenon that pre-dispersed nano silicon and nano oxidized aluminum solutions can effectively improve coating elevation construction sagging.But the system that this application relates to is the polymer cement waterproof paint of ACRYLIC EMULSION system, does not relate to the impact on coating elevation construction, and does not relate to and improve material at the splitting resistance of unfairness base layer construction.
Summary of the invention
Technical problem solved by the invention is in order to overcome the easy sagging of polymer cement waterproof paint elevation construction that the existing VAE of take emulsion is raw material, on irregular basal plane, cloudy external angle position is more prone to the defects such as cracking phenomena, and a kind of new II type polymer cement waterproof paint and preparation method thereof is provided.Polymer cement waterproof paint of the present invention has carried out the preferred of formula and has improved on the basis of existing formula, can on the basis of low polymer cement ratio, realize not sagging of elevation construction, not easy to crack at unfairness base layer construction, with the desirable texts of adhesiveproperties of basic unit.
