preparation example Construction

[0109] According to a third aspect of the present invention, a method for preparing the above-mentioned anti-oxidation coating is provided, comprising the following steps:

[0110] The antioxidant is uniformly mixed with other raw materials in the paint to obtain the antioxidant paint.

[0111] The coating can be prepared according to conventional techniques in the art, and then the antioxidant containing D-isoascorbic acid and / or its salt is added to the coating and mixed evenly. The preparation process is simple to operate and has no adverse effect on the stability of the paint product.

Embodiment 1

[0114] An anti-oxidation interior wall engineering paint, which is composed of the following components: solvent water 30%, antifreeze agent ethylene glycol 0.5%, dispersant AR-1 0.5%, wetting agent SF-1 0.1%, multifunctional additive Codis-99 0.1%, defoamer T-503 0.1%, antioxidant D-sodium erythorbate 0.5%, preservative K55 0.1%, pigment anatase titanium white 3%, filler kaolin 6%, filler heavy calcium (800 mesh ) 20%, filler light calcium (1000 mesh) 10%, filler talc powder (1250 mesh) 8%, film-forming aid alcohol ester-120.5%, defoamer T-503 0.1%, styrene-acrylic emulsion GC-6590 20 %, thickener MS-2 (1:1 water) 0.5%.

Embodiment 2

[0116] An anti-oxidation interior wall engineering paint, composed of the following components: solvent water 20%, antifreeze agent ethylene glycol 0.5%, dispersant AR-1 0.5%, wetting agent 104PG50 0.1%, multifunctional additive Codis- 99 0.1%, defoamer Tween 0.1%, antioxidant D-sodium erythorbate 0.5%, preservative K55 0.1%, pigment cobalt blue 3%, filler kaolin 6%, filler heavy calcium (800 mesh) 20%, filler Light calcium (1000 mesh) 10%, filler talc powder (1250 mesh) 8%, film-forming aid ethylene glycol monobutyl ether 0.5%, defoamer T-503 0.1%, styrene-butadiene emulsion L-8242 30%, Thickener MS-2 (1:1 water) 0.5%.

Abstract

The present invention discloses applications of D-isoascorbic acid and / or a salt thereof in coating materials, and anti-oxidation coating material and a preparation method thereof, and relates to thetechnical field of coating materials. The invention further discloses applications of D-isoascorbic acid and / or a salt thereof as an antioxidant and a color protection agent in coating materials, andan anti-oxidation coating material and a preparation method thereof, wherein the anti-oxidation coating material comprises an antioxidant, and the antioxidant comprises D-isoascorbic acid and / or saltsthereof. According to the present invention, the technical defects of poor anti-oxidation ability and easy aging of the current coating materials are relieved; with the applications of the D-isoascorbic acid and / or salts thereof in the coating materials, the coating material has advantages of oxidation resistance and excellent color protection effect, the bright paint surface can be maintained for a long time, and oxidation, color fading, cracking, shedding and other aging phenomena can be effectively retarded; and the D-isoascorbic acid and the salt thereof are the food-grade antioxidants, and have advantages of safe use, no toxicity and no pollution.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an application of D-erythorbic acid and / or its salt in coatings, an anti-oxidation coating and a preparation method thereof. Background technique [0002] Ascorbic acid and its salt are a new type of food anti-oxidation, anti-corrosion, and fresh-keeping agent, which can effectively reduce the oxidation of food, prevent its color, aroma, and taste from fading, and help the color of meat products and seafood. At the same time, it can also inhibit food The formation of carcinogen nitrite in human body has the functions of lowering blood pressure, diuresis and detoxification in medicine. At present, this product has been widely used in meat, fruit, beverage and other foods. In recent years, the application of ascorbic acid as an antioxidant in the fields of wool spinning, electroplating, feed processing, industrial water treatment and petrochemical industry has gradually been expa...
