Embodiment Construction

[0040] A kind of embodiment of high stability latex paint formula, by weight:

[0041] 1. Water: 194

[0042] 2. Sodium polyphosphate dispersant: 5

[0043] 3. Wetting agent: 2

[0044] 4. Preservative ParmetoLA26: 3

[0045] 5. Defoamer: 3

[0046] 6. Hydroxyethyl cellulose thickener (4% aqueous solution): 60

[0047] 7. Polyurethane thickener (HEUR): 2

[0048] 8. Alkali-swellable thickener (ASE): 12

[0049] 9. Alkali-swellable thickener (HASE): 2

[0050] 10. Coalescent Texanol: 7

[0051] 11. Titanium dioxide: 100

[0052] 12. 5UM calcium carbonate Omyacrh5GU: 370

[0053] 13. Emulsion Acronal29U: 240

[0054] In this embodiment, the 6 components are organic thickeners. Due to the hydrogen bond, it has high hydration and the entanglement between molecules. When it is added to latex paint, it can immediately absorb a large amount of water, making its volume greatly Swelling, and at the same time, the high molecular weight thickeners are entangled with each other...

Abstract

The invention provides high-stability emulsion paint, which is characterized by comprising the following components in parts by weight: (a) 170-230 parts of water, (b) 3-7 parts of poly(sodium phosphate) dispersant, (c) 0-5 parts of wetting agent, (d) 1-5 parts of preservative Parmeto LA 26, (e) 1-5 parts of antifoaming agent, (f) 40-80 parts of hydroxyethyl cellulose thickening agent, (g)1-3 parts of polyurethane thickening agent (HEUR), (h) 9-15 parts of alkali swelling type thickening agent (ASE), (i) 1-3 parts of alkali swelling type thickening agent (HASE), (j) 5-9 parts of film forming auxiliary Texanol, (k) 70-130 parts of titanium white, (l) 340-400 parts of 5UM calcium carbonate Omyacrh 5GU, and (m) 210-270 parts of emulsion Acronal 29U. The invention is favorable for improving the storage stability of the emulsion paint as well as the film forming effect.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a high-stability latex paint. Background technique [0002] The formulas of latex paints currently on the market are mainly as follows: [0003] (Referring to latex paint and ecological latex paint practical manual page 364 "flat exterior wall latex paint formula) in parts by weight [0004] 1. Water: 129 [0005] 2. Hydroxyethyl cellulose thickener Natroso1250HBR (2%): 130 [0006] 3. Sodium polyphosphate dispersant: 3 [0007] 4. Pigment DisperserA: 2 ammonium polyacrylate dispersant [0008] 5. Preservative ParmetoLA26: 3 [0009] 6. Defoamer: 3 [0010] 7. No. 200 solvent oil: 13 [0011] 8. Coalescent Texanol: 7 [0012] 9. Titanium dioxide: 100 [0013] 10. 5UM calcium carbonate Omyacrh5GU: 370 [0014] 12. Emulsion Acronal29U: 240 [0015] Total: 1000 copies [0016] The common problem of the production quality of existing latex paint is the storage stability of latex p...
