Summary of the invention
The technical issues that need to address of the present invention are to disclose thick slurry priming paint of a kind of elasticity and its production and application, to overcome defective and the deficiency that prior art exists.
The thick oar priming paint of elasticity of the present invention is a kind of mixture, and its component and parts by weight comprise:
Acrylic resin 30-45
Defoamer 0.1-0.5
Tensio-active agent 0.1-0.5
PH regulator agent 0.1-0.5
Biocide mildewcide 0.2-0.8
Natvosol 0.1-0.5
Acrylic fibre 0.01-0.10
Titanium dioxide 2-5
Filler 30-50
Water 8-15
Wherein, acrylic resin is the rubber-like emulsion, has very strong elasticity and good elongation, can adapt to the motion of crackle on the sand-cement slurry surface, makes foundation wall sand-cement slurry aspect and breaks or purse up, and can reach best decoration and protection and protect performance.Can adopt the commercially available prod, as adopting the ROHM AND HAAS ACRYLIC EMULSION.
Said defoamer is mineral oil and fatty acid mixt, and it has extremely strong their defoaming function, can adopt the defoamer of Henkel Corp.;
Said tensio-active agent is a trisodium phosphate, and it is more abundant that powder is disperseed;
Said pH regulator agent is an ammoniacal liquor, and ammoniacal liquor is specifically designed to the pH value of regulating priming paint as a kind of acid number conditioning agent.Because common metope is the sand-cement slurry class metope of high pH value, makes the pH of priming paint and metope consistent;
The different plug of the preferred 5-chloro-of said biocide mildewcide 2-methyl-4-frustrates-and 3-position (CIT) and imines benzene frustrates carbamate, makes the quality guaranteed period of coating longer;
Water is a kind of solvent, and making priming paint is environment-friendly type priming paint;
Said acrylic fibre silk has splendid dispersiveness and good cohesiveness, can priming paint inner form three-dimensional uniformly disorderly to support system, thereby raising crack resistance, strengthen impervious ability, the back cover effect is strengthened, and strengthening shock resistance and shock resistance, increase aspect freezing tolerance, is a kind of efficient temperature compensation cracking resistance means;
Titanium dioxide is the white pigment powder, belongs to Rutile type Titanium Dioxide, has stronger weathering resistance;
Said filler is that lime carbonate and calcite powder are filler, makes good opacifying power of priming paint tool and thickness.
The thick oar priming paint of elasticity of the present invention is the preparation method comprise the steps:
Said components is prepared in the following manner: elder generation is with water in the dispersion machine that band stirs, defoamer, tensio-active agent and ammoniacal liquor, biocide mildewcide slowly mixes under 500 revolutions, add titanium dioxide, lime carbonate and calcite powder, under the situation of high speed rotating, rotated 20~30 minutes, when treating that its fineness reaches 30~40 microns, speed is lowered 500 right stirrings of turning left, add ACRYLIC EMULSION and acrylic fibre, regulate viscosity with Natvosol at last, promptly obtain the thick slurry priming paint of said elasticity.
The suitable construction temperature of the thick oar priming paint of elasticity of the present invention is that 5~40 ℃, humidity are 50~85%, smears with common cylinder, and its smearing thickness is 2~3 times of common priming paint, can solve the unfairness and the cracking of metope, the use that minimizing face is coated with, saving cost.
Priming paint of the present invention is a kind of priming paint of thick slurry, directly uses, and can get final product with the cylinder roller coating during use.Because this priming paint is a kind of resilient thick slurry priming paint, also available elastic drum is done the elasticity decorative pattern, as in be coated with use.
Thick slurry priming paint opacifying power of the present invention is good, can be suitable for different metopes.The metope unfairness is as using.Coating can consume a large amount of coating, has increased operation and consumption as batch greasy giving, and has increased cost.As use thick slurry priming paint as long as batch one be coated with, and can solve the unfairness of metope, can economize putty again and face is coated with, be easy to the rimose problem owing to having used elastic emulsion and acrylic fibre silk to solve thick slurry priming paint simultaneously.
Adopt the non-all events of GB/T-9755-2001 to detect, its result is as follows:
