Abstract
The present invention relates to a kind of technology for producing coating, the raw material that is adopted in this technology comprises: starch, sulfuric acid, potassium permanganate, caustic soda, borax, urea, lime carbonate, talcum powder, titanium dioxide and water, manufacturing process has operations such as glue, batching, color matching and grinding, and glue then comprises steps such as removing robust fibre, oxidation, gelatinization and complexing.According to the coating of technology of the present invention preparation have that adaptability is strong, cohesive force strong, good stability, the aging and low advantage of cost, be a kind of water-soluble air-dried coating.
Description
The present invention relates to a kind of new coating manufacturing technology, particularly relate to a kind of new coating of water-soluble self-drying type.
Along with growth in the living standard, architectural decoration is towards variation and superior development, and wherein the coating decoration is universal and main decoration mode, and still, there are two big shortcomings in existing coating, and promptly cost is too high and easy to be aging.
The objective of the invention is to provide a kind of manufacturing technology of water-soluble air-dried coating, strong by the new coating adaptability of this technology preparation, bonding force is strong, and good stability is difficult for aging, and cost is low.
For achieving the above object, the raw material that adopted of new coating manufacturing technology of the present invention comprises sizing material, filler and colorant.Manufacturing process comprises: glue, batching, color matching and grinding etc., the glue operation then comprises steps such as robust fibre, oxidation, gelatinization and complexing, owing to adopted these steps, the present invention has prepared the water-soluble air-dried coating of excellent property with several common and cheap raw materials.
Advantage of the present invention and usefulness can be showed from following description of preferred embodiments in more detail.
One, raw material applicable elements and standard
Starch: the pure white amorphous powder, fineness can not surpass 90 orders, and moisture content is less than 13%, and protein is less than 0.9%, and ashes is less than 0.5%.
Potassium permanganate (KMnO
4): the crystal of the little tool metalluster of intense violet color, the solubleness in the time of 20 ℃ in water are/100 milliliters of 6 grams.
Borax: colourless translucent crystal, the solubleness in the time of 20 ℃ in water are/100 milliliters of 2.7 grams.
Sulfuric acid: concentration about 96%, density about 1.83.
Light calcium carbonate: white powder, more than 200 orders.
Talcum powder: white powder, more than 200 orders.
Titanium dioxide contains ferro element pigment, caustic soda, the equal industry standard of urea.
Two, prescription
Starch 150Kg 3MH
2SO
415 liters
150 liters of 3%KMnO of 2% borax
490 liters
45 liters of urea 1.5Kg 30%NaOH

360-90Kg
400 liters of titanium dioxide suitable quantity of water
Three, manufacturing process
A. with starch and pH value is 10 NaOH reaction, and volume ratio is 1: 2, filters the removal robust fibre with 100 order filter cloths.
B. by formula rate starch is added reactor, add 55% water, stir, add 3MH then
2SO
4And 3%KMnO
4Solution stirring is even.
C. in the product of process B, add the water and the NaOH of surplus, make starch pasting, have the flowability and transparency of stability to it till.
D. in the product of operation C, add borax and stir.
E. adding in the product of step D that urea stirs is composite adhesives again.
F. in the product of E operation, add CaCO
3And stir.
G. in the product of F operation, add talcum powder and stir.
H. adding an amount of pigment in the product of G operation mixes colours.
HH. above-mentioned final product is added shredder (paste roller mill) and grind, so just obtained coating finished product of the present invention.
