Problems solved by technology

[0002] Existing wall paint coatings, the production process is generally all relatively simple, and its decorative effect causes poor adhesion due to insufficient coating of the coating, and its coating adhesion is generally 0.2~0.7Mpa; Its water resistance, wear resistance is poor, easy Moldy and easy to crack. At the same time, the above problems caused by the improper distribution of its components have brought great inconvenience to the construction.

Embodiment 1

[0024] Wash the stainless steel reaction tank, add 36% of total weight of water, 2% of HEC, add 0.5% of total weight of dispersant, adjust the mixer to 1200 rpm, stir for 25 minutes, mix well, and let stand for 5 minutes. Add 25% magic color powder, 30% pure acrylic emulsion, 6% film-forming aid, 0.2% negative ion additive of total weight again, stirrer is adjusted to 400 revs / min, low speed stirs 30 minutes. Then add 0.5% polyurethane, 0.2% bentonite, 0.2% NXZ, adjust the pH value to 8-9, adjust the speed to 400 rpm, stir for 15 minutes, and wait for half an hour before filling the paint to make a nanocomposite Invisible illusion paint.

[0025] The product quality reaches: (1) state in the container: no hard lumps, uniform state after stirring; (2) construction: two coats without obstacles; (3) appearance of the coating film: normal appearance; (4) low temperature stability: No deterioration; (5) Contrast ratio / %: ≥0.95; (6) Drying time (surface dry) / h: ≤2 hours; (7) voc / g....

Embodiment 2

[0027] Clean the stainless steel reaction tank or homogenizer, the first step: mix water, HEC, dispersant and other additives first; the second step: add negative ion additives, magic powder, pure acrylic emulsion, film-forming aids, HEC Mix evenly, adjust the mixer to 1200 rpm, stir and cut at high speed for 20 minutes; the third step: add polyurethane, leveling agent, NXZ, pH regulator, adjust the speed to 400 rpm, and stir at low speed for 20 minutes. That is to make nano-composite invisible illusion paint, filter and pack.

[0028] The product quality reaches: (1) state in the container: no hard lumps, uniform state after stirring; (2) construction: two coats without obstacles; (3) appearance of the coating film: normal appearance; (4) low temperature stability: No deterioration; (5) Contrast ratio / %: ≥0.95; (6) Drying time (surface dry) / h: ≤2 hours; (7) voc / g.L-1: ≤120; (8) Alkali resistance (dipping 96h): no abnormality; (9) free formaldehyde / g.kg-1: 0.1; (10) soluble c...

Abstract

The invention discloses a wall surface paint composition and a preparation method thereof. The composition comprises 36% of water, 30% of pure acrylic emulsion, 25% of natural multicolor powder, 6% of film forming assistant, 0.2% of HEC (hydroxyethyl cellulose), 0.5% of dispersant, 0.7% of propylene glycol, 0.5% of polyurethane, 0.3% of preservative, 0.2% of NEX, 0.1% of pH regulator and the like. The preparation method comprises the following steps: mixing the water, HEC and dispersant in percentage by weight at a high rotation speed of 1200 rpm, and mixing with other components in percentage by weight at a low rotation speed of 400 rpm. The coating of the wall surface paint prepared by the method disclosed by the invention has the wall artistic effects of high adhesive force, easily adjusted pattern, high drying speed, simple manufacturing method, high construction convenience and favorable decoration performance. The coating has the advantages of high water resistant rate, scrubbing resistance, smooth feel, favorable color protection performance, high mildew resistance, high cracking resistance and high weather resistance.

Description

technical field [0001] The invention relates to a coating composition and a preparation method thereof, more particularly to a wall paint composition and a preparation method thereof. Background technique [0002] Existing wall paint coatings, the production process is generally all relatively simple, and its decorative effect causes poor adhesion due to insufficient coating of the coating, and its coating adhesion is generally 0.2 to 0.7Mpa; its water resistance and abrasion resistance are poor, easy to Mildew and easy to crack. At the same time, the above-mentioned problems caused by the improper distribution of its components have brought great inconvenience to the construction. Contents of the invention [0003] The purpose of the present invention is to provide a kind of wall paint coating composition, to solve the above-mentioned problems existing in the prior art, the coating that forms with the coating composition of the present invention has strong adhesion, patte...
