Problems solved by technology

For example, the interior wall latex paint in the patent CN1673294A contains composite nano-anion powder, which is silicate mineral powder modified by nano-photocatalyst material, and its anion release ability is not strong enough
The interior wall paint in CN104059445A contains activated negative ion powder, but its composition is not specified, and its negative ion release ability is not measured
In CN104513572A, the base paint adopts electrically activated nano-tourmaline as the negative ion additive, and in CN104371436A, the inner wall latex paint adopts the nano-tourmaline slurry as the negative ion slurry, but the consumption of the two negative ion raw materials is relatively large relative to the paint, and the cost is relatively high
[0004] CN103305070A contains raw materials such as medical stone nanopowder, silicon dioxide nanopowder, titanium dioxide nanopowder, superfine calcium carbonate nanopowder, etc. in the interior wall environmental protection paint, wherein contains metal element oxide raw materials, and these raw materials consumption is relatively large, in addition the The patent also does not specify its ability to release negative ions
Similarly, the nano-powder content of nano-silica, tourmaline and medical stone contained in the coating in CN102093791A is also relatively large, and its negative ion release ability is not disclosed

Embodiment 1

[0047] Prepare nano anion functional type white interior wall latex paint by the formula weight part of table 2, comprise the following steps:

[0048] a) Prepare raw materials according to the weight parts set by the formula, put hydroxyethyl cellulose, purified water, antifreeze, titanium dioxide, water-soluble composite nano-anion powder, and fillers into the container in turn and stir at a high speed of 1400-1600 rpm, After stirring evenly, grind on a horizontal sand mill until the fineness is ≤30 μm, then transfer it to a mixing container, reduce the speed to 800 rpm, add polymer emulsion, film-forming aid, and leveling agent, Add thickener to adjust to the viscosity required by customers.

[0049] b) Detection-filter-package-sample retention.

Embodiment 2

[0051] The adjustment of the formula ratio of this embodiment is shown in Table 2. The specific implementation process is basically the same as that of Example 1, the only difference being that the high-speed stirring speed is 1200-1400 revolutions per minute, and the stirring time is 30 minutes.

Embodiment 3

[0053] The adjustment of the formula ratio of this embodiment is shown in Table 2. The specific implementation process is basically the same as that of Example 1, the only difference being that the high-speed stirring speed is 1200-1400 revolutions per minute, and the stirring time is 15 minutes.

Abstract

The invention discloses a nano negative ion functional interior wall latex paint and a preparation method thereof. The interior wall latex paint comprises the following components by weight: 120-150 parts of polymer emulsion, 3-5 parts of hydroxyethyl cellulose, 2-5 parts of water-soluble composite nano-anion powder, 15-25 parts of antifreeze, 7-9 parts of film aid, 3-6 parts of thickener, 3-5 parts of leveling agent, 180-220 parts of filler, 350-450 parts of water. In the present invention, by adjusting the formula structure and adding water-soluble composite nano-sterilizing powder, it has the effect of continuously releasing negative ions, purifying the air, and improving human immunity. The water-soluble composite nano-negative ion powder is passed through crystal, quartz, vermiculite, medical stone, Two or more kinds of tourmaline are made by nano-grinding. The interior wall latex paint of the invention is environment-friendly, high-efficiency, energy-saving, safe and low in cost, can efficiently release negative ions, has strong practicability and broad application prospects.

Description

technical field [0001] The invention relates to the technical field of interior wall latex paint, and particularly discloses a nano negative ion functional interior wall latex paint and a preparation method thereof. Background technique [0002] The interior wall latex paint sold in the market has mixed brands and uneven quality. Some of them contain harmful substances such as heavy metals, etc., and release formaldehyde, VOC (volatile organic compounds), etc., which will be harmful to the human body. Cause poisonous, serious pollution to the environment. Negative ions are known as "air vitamins and growth hormones". Like vitamins in food, negative ions have a very important positive impact on the life activities of the human body and other organisms. The level of negative ion content is an important index to evaluate the environment and air quality. [0003] Some patented technologies have added negative ions to interior wall paints to achieve environmental protection. F...
