Abstract

The dry-powder building coating is a monocomponent product which is made up by using film-forming material, pigment, filler and adjuvant, etc. and mixing them by stirrer. Said invented product features simple prodn. equipment, convenient storage and transportation and low cost. When using, said dry-powder coating material and water are stirred according to the mixing ratio of 1:2, and made into a thick liquid, so that said thick liquid can be brushed or sprayed on internal wall so as to obtain decorative effect. Said invented product can be mixed with other raw material, and can be made into washable coating material, latex paint, external wall coating and coloured coating material, etc..

Description

The manufacture method of dry powder building coating and operation instruction

The present invention relates to the manufacture method and the operation instruction of building coating, the particularly manufacturing of dry powder building coating and use.

Building coating is to cover with paint, lacquer, colour wash, etc. at building surface, thereby plays the effect of protection and decorating wall.In recent years, large quantities of water-based pulpous state coating for internal and external wall listings has not only improved decorative effect, also makes the user feel easy construction, the benefit of saving aspects such as man-hour.But, caused inevitably because the product of water-based pulpous state (or emulsus) leaves in the big and small pail pack: the one, the difficulty of remote transportation; The 2nd, the shelf-time (general half a year following) is unsuitable long, and some requires storage condition (temperature is more than zero degree centigrade, antifreeze sun-proof etc.) etc.; The 3rd, the unicity of product use aspect (a kind of product just can only be equally to make method).

In order to overcome the above deficiency of saying, the objective of the invention is: by several raw materials in the middle of the original manufacturing building coating process through the water distribution glue-stirring-packing of pulling an oar-grind-filter-join, be reduced to through reselecting raw material, as long as sieve-stir-pack, key link is that batching stirs convenient and easy less investment.And change dry powder into by water-based, packing material is changed into woven bag by bucket, and period of storage can be more than 3 years, and the transportation electrode is for having made things convenient for.

Implementation method of the present invention is:

1, composition of raw materials (weight ratio):

Filmogen 5.5

Carbon is joined calcium 68

Talcum powder 10

Wollastonite 10

Pigment 6

Auxiliary agent 0.5

2, production technique:

Above various raw materials are sieved in (120 order), drop in the conical agitator, stirred at normal temperatures 30-40 minute, the blowing packing.

3, using method:

(1) 1 part of this product is joined 2 parts of tap water (weight ratio),, can or brush on interior wall or roll or spray, reach the not decorative effect of dry linting of dry back (surface drying 1 hour, absolutely dry 24 hours) at the container for stirring pulp.Through check, meet national JC361-85 coating standard.

(2) other class products of conversion thus:

A, converting last 107 glue (or 107 glue thickening materials) by 20% of amount of water, is washable interior wall coating.

B, convert white glue with vinyl by 30% of amount of water, 8% of amount of water is converted lithopone, stirs some times more, is emulsion paint.

C, converting 6% of BC-01 emulsion, amount of water by 35% of amount of water and convert titanium dioxide, is exterior coating.

D, allocating within the slip with different pigment, is band look coating.

E, in 1: 0.4 (dry powder paint: ratio furnishing paste water), use silieonized plate to scrape on the wall, just formed water-fast good, middle-grade porcelain-imitated coating that gloss is bright.

Claims

1, a kind of dry powder building coating is by being after base-material, adding auxiliary agent change its cross-linking properties, to add pigment again and improve opacifying power to meet the quick-dissolving filmogen of water under the normal temperature, adds filler and serves as bone material, a kind of product that mixes together.The product service performance, the one, convert water and stir and can use, the 2nd, select for use several other raw materials to be blended into and can improve the coating class.

2, according to the described manufacture method of claim 1, it is characterized in that filmogen must be quick-dissolving, comprise modified starch, its consumption accounts for 5.5% (± 0.2).

3, according to the described manufacture method of claim 1, its feature also is to add appropriate amount of addition agent to change cross-linking properties, comprises wilkinite, and its consumption accounts for 0.5% (± 0.1).

4, according to the described using method of claim 1, it is characterized in that it being a kind of product, can also become several products that improve grade, mainly be filmogen (modified starch) and the auxiliary agent (wilkinite) in the middle of the product, with 107 glue (or 107 glue thickening materials), white glue with vinyl and raw materials such as lithopone, BC-01 emulsion and titanium dioxide, after continuing respectively to mix stirring, can not destroy or reduce the reaction of former filmogen performance, selected ratio is the aritical ratio that meets national coating standard.
