Abstract

This paint is prepd. by blent from two or more kinds of monocolor powder which is powdered plant after treatment of dyeing, washing, dewatering and drying. When using it a plain powder blower is needeed merely and a polychromatic napped effect can be formed with once coating.

Description

The multi-color powder paint having nap surface effect production method

The present invention relates to a kind of building coating, particularly a kind of multi-color powder paint having nap surface effect.

At present, the coating of multi-colour pattern that generally is used in inner wall decoration is the product of liquid form, needs water or organic solvent to make medium, staging life, is short, the easy layering of long-term storage, rotten, and toxicity is big when production, construction, investment of production equipment is big, need purchase air compressor machine and special-purpose spray gun during construction.The metope static flocking is the another decoration technique of popular in recent years, and color and luster is abundant, plentiful, the rich and magnificent decorative effect of texture though have, and exists very easily to be stained with ash, non-scrubbing resistance, raw material difficulty and to purchase, and construction need be purchased defectives such as static flocking machine.

The objective of the invention is in order to overcome the deficiency of original technology, and provide a kind of practicality stronger decorative paint--multi-color powder paint having nap surface effect.It has following characteristics:

1. be dry powder, packed and transported, storage, extremely easy to use, long-term storage is never degenerated.

2. decorative effect uniqueness, rich color, color and luster are soft, rich texture, stereoscopic sensation are strong.

3. the raw materials for production main raw material is an agricultural waste, and it is rich and easy to get to originate, and material cost is very cheap.

4. be coated with facing and be difficult for being stained with ash, can clean after dirty.

5. easy construction is easily gone, and need not purchase expensive device such as air compressor machine, flocking machine, and speed of application is fast.

The present invention pulverizes the dyed processing of material and composite making with plant.Its manufacture craft process is:

(1) earlier plant was pulverized the 30--50 mesh sieve, screenings is pulverized the back after the 30--50 mesh sieve through pulverizer again, and the collection outsifting is standby.

(2) water, dyestuff, salt are added to boil in proportion dye in the pot, stirring and dissolving becomes staining fluid, adds pure plant powder, is warming up to 100 ℃ and boils 30 minutes, constantly stirs.

(3) take the dish out of the pot and carry out processed, add water washing, dry into centrifuge.

(4) dry or dry after monochromatic powder.

(5) by the color requirement of product, that two or more colored powders is composite in proportion, homogenizing is handled, with plastic bag sealing pack finished product.

Embodiment:

(1) corn cob is pulverized with pulverizer, crossed 50 mesh sieves, screenings is again through pulverizing, and after 50 mesh sieves, the collection screening is standby.(2) 20 gram substantive dyestuff and 200 gram salt are added to boil dye in the pot, add entry 5000 ml waters, stir and make it be dissolved into dye liquor, add 1000 gram corn cob powders then, should fully soak powder with dye liquor and be as the criterion, stir.Be heated to and boil, kept 30 minutes.(3) pollutant is pulled out from pot, gone into centrifuge and dry, and add water washing, dry again.(4) will dry thing put into dryer or airing do to moisture content 10% below red powder, with above same method, adopt direct yellow dye to dye, must yellow powder.Restrain and the yellow powder of 600 grams by red powder 1000,10 gram flashlight powders mix, and go into amalgamator and carry out the homogenizing processing, get finished product.

The technical indicator of product of the present invention is as follows:

1. water content≤10%

2. fineness 95% is by 50 mesh sieves

3. appearance of coat: thickness is even, the color unanimity

4. sticking power: with bristles brushes (staple length 10--15mm) back and forth drag wipe 1000 times not show-through

5. thermotolerance: 80 ℃ of 8 hours no changes

The constructing operation method of product of the present invention is as follows:

1. at first be coated with tackiness agent earlier one, require to be coated with to such an extent that thickness is even at smooth metope.

2., multi-color powder paint having nap surface effect is sprayed on the adhesive coating as yet not before the dry solidification at metope institute coating adhesive, requires spraying evenly, fully adhesive coating is hidden with powder sprayer.

3. after boning firmly when the first road tackiness agent dry solidification and with colorful matte dry powder, fall the not powder of bonding with bristles brush brush, and then on the first road coating, be coated with the second road tackiness agent.

4. at the second road tackiness agent as yet not before the dry solidification, the colorful coating for woolen surface in spraying second road on the second road adhesive coating again.

5. work as the second road tackiness agent complete drying and solidify, and after tying colorful matte dry powder firmly, brush the not powder of bonding with the bristles brush again, promptly finish construction overall process.

Claims

1. the production method of a matte dry powder paint is characterized in that with plant pulverizing material be main raw material, dyed processing, and operations such as washing, dry, dry or dry day, be composite is made.

2. the colorful coating for woolen surface of dry powder according to claim 1 is characterized in that used plant pulverizes material package and draw together corn cob meal, sawdust powder, straw powder, peanut hull meal etc.

3. according to claim 1,2 described methods is characterized in that, used plant is pulverized material, is sieve part of 30--50 mesh sieve.

4. method according to claim 1, it is to adopt substantive dyestuff that plant is pulverized the painted dyestuff of material.

5. method according to claim 1 boils when it is characterized in that dyeing that to dye temperature be 100 ℃, and the time is 30 minutes.

6. method according to claim 1 is characterized in that, makes monochromatic powder earlier, then, more multiple monochromatic powder is re-dubbed colorful coating for woolen surface.
