Abstract

The invention discloses a waterproof coating and a preparation method thereof. The preparation method comprises the following steps that 1, 5 to 15wt% of polyving akohol is added into a reactor, is added with water, is stirred, and is added with hot water so that a temperature is in a range of 90 to 100 DEG C and polyving akohol is completely dissolved in the reactor; 2, 1 to 2wt% of sodium tetraborate having a concentration of 0.4% is dropwisely added into the reactor with stirring and undergoes a cross-linking reaction with polyving akohol at a temperature of 75 to 80 DEG C for 40 to 60 minutes so that polyving akohol is gelated; 3, the reactor is cooled by cooling water so that a temperature is reduced to 20-30 DEG C; the reaction products are filtered and are added into a mixer; and 5 to 10wt% of sodium bentonite, 20 to 35wt% of sierozem powder and 10 to 20wt% of white cement are added into the mixer; the mixture in the mixer is stirred by the mixer for 50 to 70 minutes, then is added with 0.1 to 0.5wt% of a mildew preventive SKANEM-8, then is sequentially stirred for 5 to 15 minutes, then is added with 0.1 to 0.25wt% of a thickener NATROSOL250, then is stirred and then is grinded to form the waterproof coating. The waterproof coating has waterproof, moistureproof and mildewproof functions, prevents seepage after water immersion, has strong binding power, is not pulverized, does not fall off, has no toxicity and no odor, has a long service life and is convenient for construction.

Description

Waterproof paint and preparation method

Technical field

The present invention relates to a kind of chemistry painting industry that is used for building trade, the invention still further relates to the preparation method of this coating.

Background technology

Be used for now porcelain-imitated coating that indoor wall, top ceiling decorate on the market, just change coating, dry powder paint etc.; Owing to do not have waterproof, moisture proof, leakage performance; In case body of wall, top ceiling etc. have drainage; Coating is just drenched easily, causes fall in flakes, efflorescence, mouldy, can not adapt to the needs of modern architecture decorative craft.

Summary of the invention

The object of the present invention is to provide a kind of waterproof, mildew-resistant, strong adhesion, non-chalking wall lining coating.

Another object of the present invention is to provide the preparation method of this waterproof wall paint.

The technical scheme that adopts is:

Waterproof paint, process by the following weight proportion raw material:

Z 150PH 5-15, water 50～100,0.4% (weight) sodium tetraborate solution 1-2, sodium bentonite 5-10, grey calcium powder 20～35, white cement 10～20, SKANEM-8 mould inhibitor 0.1～0.5, NATROSOL250 thickening material 0.1～0.25.

Above-mentioned raw materials is prepared the method for waterproof wall paint of the present invention, may further comprise the steps successively:

(1) Z 150PH is added in the reactor, add entry then, stir, heating water temperature to 90～100 ℃ make that Z 150PH dissolves fully in the reactor;

(2) sodium tetraborate solution is slowly splashed in the reactor and Z 150PH generation crosslinking reaction with the thread mode under constantly stirring;

(3) drip off sodium tetraborate solution after, keep 75-80 ℃ thermotonus 40-60 minute, make polyvinyl alcohol gelization;

(4) reacted after, use the water quench reactor, make its temperature reduce to 20-30 ℃, filter, colorless glue;

(5) above-mentioned colorless glue is added in the stirrer, add sodium bentonite, grey calcium powder and white cement again, start is stirred, and after 50-70 minute, adds the SKANEM-8 mould inhibitor, continues to stir after 5-15 minute, adds the NATROSOL250 thickening material, and then stirs;

(6) stir after, put into shredder and grind, promptly make waterproof wall paint of the present invention.

The present invention with existing various imitative porcelain, just change coating and compare; Have that waterproof, protection against the tide, mildew-resistant, water logging are non-leakage, bonding strong adhesion, not efflorescence, do not come off, characteristics such as nonpoisonous and tasteless, long service life, easy construction; Be applicable to luxurious hotel, office building, interior decoration at home, also can be used as the waterproof paint of vault, underground storehouse body of wall.

Embodiment

Waterproof paint and preparation method are that the 50kg Z 150PH is added in the reactor, add 5kg water then, stir, and heating water temperature to 90 ℃ makes that Z 150PH dissolves fully in the reactor; Be that 0.4% sodium tetraborate solution slowly splashes in the reactor and Z 150PH generation crosslinking reaction with the thread mode under constantly stirring with the 1kg concentration expressed in percentage by weight; After dripping off sodium tetraborate solution, kept 75 ℃ of thermotonuses 40 minutes, make polyvinyl alcohol gelization; After having reacted, use the water quench reactor, make its temperature reduce to 22 ℃, filter, get colorless glue; Above-mentioned colorless glue is added in the stirrer, add 5kg sodium bentonite, 20kg ash calcium powder and 10kg white cement again, start is stirred; After 50 minutes, add 0.1kg SKANEM-8 mould inhibitor, continue to stir after 8 minutes; Add the 0.1kgNATROSOL250 thickening material, and then stir, after stirring; Put into shredder and grind, promptly make waterproof wall paint of the present invention.

Claims

1. waterproof paint is characterized in that being processed by the following weight proportion raw material:
