CN105385259A - Building wall suspension-flowing color powder coating - Google Patents

Abstract

The invention discloses a building wall suspension-flowing color powder coating. The building wall suspension-flowing color powder coating consists of the following components in parts by weight: 100 parts of polyvinyl acetate emulsion, 10 to 50 parts of BA-154 emulsion, 5 to 20 parts of bentonite, 2 to 10 parts of calcium tripolyphosphate, 2 to 10 parts of magnesium oxide, 5 to 10 parts of kaolin, 0.1 to 1 part of defoaming agent, 0.1 to 1 part of preservative, 0.1 to 5 parts of pigment and 50 to 150 parts of water, wherein the particle size of the bentonite and the calcium tripolyphosphate is 20 to 200 micrometers. The building wall suspension-flowing color powder coating is high in weather resistance, high in adhesion with a wall basal body and unlikely to peel and drop and can form suspension-flowing and spotted color patterns.

Description

A kind of building wall hangs stream color powder coating

Technical field

The invention belongs to technical field of chemistry and chemical engineering, particularly relate to the production technology of white powder coating.

Background technology

Powder coating, as the one in coating type, is used in building wall in a large number.But current powder coating weathering resistance is poor, especially the coating of outdoor wall surface is through rain drop erosion and after exposing to the weather, and easy peeling comes off and variable color, needs often to repair, thus causes its use cost too high.And current coating is all straight-shade coatings, cannot once form color coating.

Summary of the invention

Goal of the invention: for above-mentioned existing Problems existing and deficiency, the object of this invention is to provide a kind of building wall and hang stream color powder coating, weathering resistance is strong, comes off with the high peeling that is not easy of the bonding force of body of wall matrix, and can form extension stream-like and mottled multi color pattern.

Technical scheme: for achieving the above object, the present invention by the following technical solutions: a kind of building wall hangs stream color powder coating, is made up of by weight following component:

Polyvinyl acetate emulsion 100 parts;

BA-154 emulsion 10 ~ 50 parts;

Wilkinite 5 ~ 20 parts;

Tripolyphosphate calcium 2 ~ 10 parts;

2 ~ 10 parts, magnesium oxide;

Kaolin 5 ~ 10 parts;

Defoamer 0.1 ~ 1 part;

Sanitas 0.1 ~ 1 part;

Pigment 0.1 ~ 5 part;

50 ~ 150 parts, water;

Wherein, the particle diameter of wilkinite and tripolyphosphate calcium is 20 ~ 200 μm.

As preferably, described sanitas is SODIUMNITRATE or Sodium Benzoate.

As preferably, described defoamer is polyether siloxane copolymers, polyoxyethylene polyoxypropylene tetramethylolmethane ether or polypropylene glycerol aether.

Beneficial effect: compared with prior art, the present invention has stronger basal body binding force and weather resistance; Utilize the wilkinite of appropriate particle size and tripolyphosphate calcium in spraying slurry, form particle block simultaneously, be adjusted to suitable viscosity during use thus formed on metope and hang stream, the color of final formation sagging form and spot color, have rich color, decorative effect that stereoscopic sensation is strong.

Embodiment

Below in conjunction with specific embodiment, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.

Embodiment 1

A kind of building wall hangs stream color powder coating, comprises the following steps:

(1) water getting 50L adds in reaction vessel, when stirring, adding the polyether siloxane copolymers of 0.5 part and the SODIUMNITRATE of 0.5 part, then adding the BA-154 emulsion of 100 parts of polyvinyl acetate emulsions and 15 parts, and the above emulsion solution of stirring reaction 30min, for subsequent use;

(2) then in another reaction vessel, add remaining water and start stirring, add 5 kaolin and 6 parts of magnesium oxide successively again, and high-speed stirring forms uniform suspension liquid, then add the tripolyphosphate calcium of 12 parts wilkinite SD-2 and 3 part, stir and at least obtain slurry after 30min; The particle diameter of wilkinite and tripolyphosphate calcium is 20 ~ 200 μm,
