The present invention discloses a preparation method for a high-grade external wall emulsion paint, wherein the product belongs to the field of chemical engineering building materials. According to the product of the present invention, water, a dispersing agent, a defoaming agent, kaolin, titanium dioxide, calcium carbonate, a C-40 film-forming aid, propylene glycol, an OBPA anti-mould agent, wollastonite, a pure acrylic emulsion, a thickener, a wetting agent, and a pigment are adopted as raw materials, and a specific process is adopted to prepare the finished product, wherein the product has advantages of flat paint film, full, brightness, strong durability, rapid drying, firm attachment, scrubbing resistance, strong covering power, good weathering resistance, stable color and the like, has characteristics of no toxicity, no odor and light providing, belongs to an environmental protection product, and is mainly used for protection of external walls of buildings.
Description
Technical field:
Product of the present invention belongs to the chemical building material field, relates in particular to a kind of preparation method of high-grade exterior wall latex paint.
Background technology:
The major function of exterior wall latex paint is to decorate and the protection external surface of buildings, makes the buildings appearance neat and artistic, can play the effect of protection skin simultaneously.Requirement to exterior wall latex paint is: exterior wall latex paint is wanted rich color, and tint retention is good, can the long period keep good decorate properties; The exterior wall long-term exposure will often receive rainwash in atmosphere, must possess good water resistance; Exterior wall latex paint must be difficult for being stain or staiing the back and be prone to clean; The coating that is exposed in the atmosphere receives under the influence and effect of many weather environment factors; Phenomenons such as general coating can occur ftractureing, peels off, shedding, variable color; Make it lose original ornamental and protectiveness; Therefore, the exterior wall latex paint coating requires in the time limit of regulation, above-mentioned breakoff phenomenon to take place, and it must possess good weather resistance.Consider according to the different of buildings class and from many-sided factors such as use costs; The exterior wall latex paint that uses has high, medium and low three kinds of class; Product of the present invention is the production technique with the advanced person; A kind of high-grade exterior wall latex paint that high-quality raw material is produced, to produce this product be raw material with water, dispersion agent, skimmer, kaolin, white titanium pigment, coarse whiting, C-40 film coalescence aid, Ucar 35, OBPA mould inhibitor, wollastonite, pure-acrylic emulsion, thickening material, wetting agent, pigment and be aided with specific technology.These product performance are good; It is the competent decoration protecting materials of external wall; Have advantages such as paint film is smooth, plentiful, bright, weather resistance strong, drying is rapid, adhere firmly, scrubbing resistance, strong covering power, good weatherability, color stable; And nonpoisonous and tasteless, light arranged, belong to environmentfriendly products, its shortcoming is that price is higher.
Summary of the invention:
The problem that the present invention mainly solves provides a kind of preparation method of high-grade exterior wall latex paint; This exterior wall latex paint is the special preparation of high standard building protection exterior wall; This product has advantages such as paint film is smooth, plentiful, bright, weather resistance strong, drying is rapid, adhere firmly, scrubbing resistance, strong covering power, good weatherability, color stable; And compound method is simple, and producing the raw material that this product uses has: water 20%, dispersion agent 1%, skimmer 0.4%, kaolin 1200 orders 4%, white titanium pigment 13%-15%, coarse whiting-900 order 10%-12%, C-40 film coalescence aid 0.2%, Ucar 35 2%, OBPA mould inhibitor 0.1%, wollastonite-700 order 9.5%, pure-acrylic emulsion 37%, thickening material 0.1%, wetting agent 0.2%, pigment 0.5%.
The present invention can realize through following technical scheme:
The method of the high-grade exterior wall latex paint of a kind of batch preparations is characterized in that being made up of following steps:
1. water is sent into vertical grinding machine, agitator is adjusted to 2000 rev/mins with rotating speed, and the temperature remains within the normal range, adds dispersion agent, skimmer successively, after stirring, adds kaolin, white titanium pigment, coarse whiting restir 50 minutes.
2. temperature is adjusted to 30 ℃, rotating speed is adjusted to 1000 rev/mins, add film coalescence aid, Ucar 35, OBPA mould inhibitor successively, and, stirred 20 minutes, reach even no particle speed drop to 600 rev/min.
3. with speed drop to 400 rev/min, add wollastonite, pure-acrylic emulsion, thickening material, wetting agent, pigment successively, stir and promptly obtained finished product in 30 minutes.
The beneficial effect of product of the present invention is: the preparation method that a kind of high-grade exterior wall latex paint is provided; It is simple, easy to operate to have technology, the exterior wall latex paint of producing has that paint film is smooth, plentiful, bright, weather resistance is strong, dry rapidly, the advantage of adhere firmly, scrubbing resistance, strong covering power, good weatherability, color stable.
