Problems solved by technology

[0003] At present, although there are many kinds of water-based paints in the domestic market, bacteria are easy to breed during their use and storage, and paintings are prone to mildew during long-term storage.
[0004] In order to overcome this problem, some researchers have added bactericides such as kasone, benzene or their derivatives to water-based paints. However, these bactericides are harmful to the human body, especially children, and the smoothness of the painting is not good enough. also slightly decreased

preparation example Construction

[0046] The invention also discloses a preparation method of water-based paint, comprising the following steps:

[0047] (A) mixing and stirring 10-60 parts by weight of toner and 30-80 parts by weight of vehicle, and grinding to obtain a color paste;

[0048](B) Alcohols and microporous materials are processed at 50~60°C for 4~5 hours to obtain modified nano inorganic antibacterial agents; the microporous materials contain at least two metal antibacterial substances; the metal antibacterial The substance is silver, zinc, gold, copper, nickel, cobalt, iron, calcium or magnesium, and the ions, oxides or complexes formed by said silver, zinc, gold, copper, nickel, cobalt, iron, calcium or magnesium ;

[0049] The color paste and 0.1-10 parts by weight of the modified nano inorganic antibacterial agent are stirred evenly at a constant speed and temperature to obtain the water-based paint.

[0050] In the present invention, the selected raw materials are toner, vehicle and modifi...

Embodiment 1

[0060] 10 parts by weight of toner and 50 parts of peach gum are mixed and stirred, and after grinding, a color paste with a fineness of 25 microns is obtained;

[0061] After n-octanol and zeolite containing silver, copper, calcium, zinc and the first metal mixture are stirred and mixed uniformly at 50°C, they are reacted for 4 hours. The first metal mixture is a mixture of iron, nickel and / or magnesium, and the The mass ratio of silver, copper, calcium, zinc and other metals is 1:(0.1-0.15):(1-1.5):(0.5-0.8):(0.008-0.01).

[0062] The obtained color paste and 0.9 parts by weight of the modified nano-inorganic antibacterial agent were stirred evenly at a constant temperature of 60° C. at 100 rpm to obtain a water-based paint.

Embodiment 2

[0064] 40 parts by weight of toner and 30 parts of acrylic emulsion are mixed and stirred, and after grinding, a color paste with a fineness of 25 microns is obtained;

[0065] Stir and mix undecyl alcohol and zeolite containing silver, zinc and a second metal mixture at 50°C for 4 hours, the second metal mixture is iron and nickel, the silver, zinc and the second metal mixture The mass ratio is 1:1:(0.2~0.3).

[0066] The obtained color paste and 0.3 parts by weight of the modified nano-inorganic antibacterial agent were stirred evenly at a constant temperature of 55° C. at 80 rpm to obtain a water-based paint.

Abstract

The invention relates to water-based drawing pigment, prepared from the following components: 10-60 parts by weight of toner, 30-80 parts by weight of a color carrier agent and 0.1-10 parts by weight of a modified nano inorganic antimicrobial agent, wherein the modified nano inorganic antimicrobial agent is prepared from an alcohol-modified microporous material; the microporous material contains at least two metal antibacterial substances; the metal antibacterial substances are silver, zinc, gold, copper, nickel, cobalt, iron, calcium or magnesium, and ions, oxides or complexes formed by the silver, the zinc, the gold, the copper, the nickel, the cobalt, the iron, the calcium or the magnesium. The water-based drawing pigment has a better antibacterial effect, the antibacterial rate of the water-based drawing pigment for bacteria such as staphylococcus aureus and escherichia coli reaches 90% or above, and the antibacterial effect lasts for at least five years; furthermore, the other properties of the water-based drawing pigment are guaranteed, for instance, the water-based drawing pigment is good in uniformity and light resistance and high in fluency.

Description

technical field [0001] The invention relates to the field of pigments, in particular to a water-based painting pigment and a preparation method thereof. Background technique [0002] Water-based paints refer to paints that can be dissolved or diluted with water, generally including watercolor paints, gouache paints, acrylic paints, acrylic paints, finger paints, Chinese paints, etc. Water-soluble paints are widely used in art teaching in primary and secondary schools. The natural interest and unique texture produced by its special painting skills also greatly stimulate students' interest in learning colors. [0003] At present, although there are many kinds of water-based paints in the domestic market, bacteria are easy to breed during their use and storage, and paintings are prone to mildew during long-term storage. [0004] In order to overcome this problem, some researchers have added bactericides such as kasone, benzene or their derivatives to water-based paints. Howeve...
