CN104098993A - Water paint and preparation method thereof - Google Patents

Abstract

The invention discloses a water paint and a preparation method thereof. The water paint is prepared from the following raw materials in parts by weight: 50 to 60 parts of pure water, 20 to 25 parts of water-based alkyd resin, 15 to 20 parts of glycerol, 10 to 15 parts of EBS (Ethylene-Bis-Stearamide),and 0.5 to 2 parts of nipagin. The preparation method comprises the following steps: weighing the raw materials in parts by weight, transferring the pure water into a reaction vessel, adding the water-based alkyd resin, stirring evenly, then sequentially adding the EBS, the glycerol and the nipagin, and stirring evenly. The water-based paint is nontoxic and non-irritant to human bodies, and is classified as a novel environmental-friendly water paint.

Description

Water-miscible paint and preparation method thereof

Technical field

The present invention relates to chemistry painting industry technical field, especially a kind of water-miscible paint and preparation method thereof.

Background technology

Water-miscible paint is to take water as thinner, take water soluble resin as film forming matter, not containing volatile organic substance, not containing benzene,toluene,xylene, formaldehyde, free TDI toxic heavy metal, nontoxic non-stimulated smell, can be applicable in the various material such as woodenware, metal, plastics, glass, building surface.With respect to traditional oil-base paint, water-miscible paint is environmental protection more, and safety is non-stimulated.

Summary of the invention

The object of this invention is to provide a kind of water-miscible paint and preparation method thereof, object is to provide a kind of novel water-miscible paint and preparation method thereof.

In order to address the above problem, the technical solution used in the present invention is:

A water-miscible paint, is prepared from by the raw material of following parts by weight: 50 parts～60 parts of pure water, 20 parts～25 parts of aqueous alkide resins, 15 parts～20 parts of glycerine, 10 parts～15 parts of the two hard acid amides of hexenyl, 0.5 part～2 parts of nipagin esters.

Preparation method comprises the following steps: the raw material that takes above-mentioned parts by weight, pure water is proceeded in reaction vessel, controlling temperature is 60 ℃～80 ℃, add while stirring aqueous alkide resin, controlling temperature is 70 ℃～80 ℃, slowly add successively while stirring the two hard acid amides of hexenyl, glycerine and nipagin esters, stir.

Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:

Water-miscible paint of the present invention is not containing volatile organic matter, nontoxic, environmental protection, and unit surface glue spread is little, cost-saving, and the enamelled coating forming after coating is smooth, tough and tensile exquisiteness, weather resisteant can be good.

 

Embodiment

Below in conjunction with embodiment, the invention will be further described:

Embodiment 1

6 kilograms of pure water are proceeded in reaction vessel, and controlling temperature is 60 ℃, adds while stirring 2 kilograms of aqueous alkide resins, controlling temperature is 80 ℃, slowly adds successively while stirring the two hard acid amides of 1.5 kilograms of hexenyls, 1.5 kilograms of glycerine and 50 grams of nipagin esters, stir, obtain water-miscible paint.

Embodiment 2

50 kilograms of pure water are proceeded in reaction vessel, controlling temperature is 80 ℃, add while stirring 25 kilograms of aqueous alkide resins, controlling temperature is 70 ℃, slowly add successively while stirring the two hard acid amides of 10 kilograms of hexenyls, 20 kilograms of glycerine and 2 kilograms of nipagin esters, stir, and obtains water-miscible paint.

Embodiment 3

550 kilograms of pure water are proceeded in reaction vessel, controlling temperature is 70 ℃, add while stirring 7200 kilograms of aqueous alkide resins, controlling temperature is 75 ℃, slowly add successively while stirring the two hard acid amides of 125 kilograms of hexenyls, 180 kilograms of glycerine and 10 kilograms of nipagin esters, stir, and obtains water-miscible paint.

Respectively to embodiment 1, embodiment 2 and the prepared water-miscible paint of embodiment 3, free formaldehyde is measured, and measurement result is in Table 1:

As shown in Table 1, this water-miscible paint free formaldehyde and benzene content are lower, nontoxic to human body, non-stimulated, and this water-miscible paint is a kind of novel green environmental friendly coatings, can be widely used in woodenware, metal, plastics, glass, building surface etc.
