Problems solved by technology

[0003] However, the ordinary luminous paint prepared in the current technology has been tested, and its luminous function can only be used five to six hundred times. If it is to be used continuously, it needs to be refurbished.

Embodiment 1

[0020] After premixing 50 parts of acrylic resin, 1.5 parts of bentonite, 3 parts of butyl acetate and 7 parts of xylene, disperse at a high speed of 2000r / min for 30 minutes with a high-speed disperser, and then add 3 parts of toluene, 34.5 parts of luminous powder and 1 part of additives are used for coloring and viscosity adjustment. The viscosity needs to be adjusted to 150±10s (coating -4 cups / 25°), and finally the impurities in it are filtered to obtain long-lasting luminous paint. Among them, the additives are luminous powder additives, defoaming agents and anti-settling agents. The particle size of the added luminous powder is 5~8μm, and the afterglow time is longer than 12h.

Embodiment 2

[0022] After pre-mixing 52 parts of acrylic resin, 1.8 parts of bentonite, 2.8 parts of butyl acetate and 7.2 parts of xylene, use a high-speed disperser to disperse at a high speed of 2000r / min for 30 minutes, and then add 2.8 parts of toluene, 34 parts of luminous powder and 1.2 parts of additives are used for coloring and viscosity adjustment. The viscosity needs to be adjusted to 150±10s (coating -4 cups / 25°), and finally the impurities in it are filtered to obtain long-lasting luminous paint. Among them, the additives are luminous powder additives, defoaming agents and anti-settling agents. The particle size of the added luminous powder is 8~12μm, and the afterglow time is longer than 12h.

Embodiment 3

[0024] After premixing 48 parts of acrylic resin, 1.4 parts of bentonite, 3.2 parts of butyl acetate and 6.8 parts of xylene, disperse at a high speed of 2000r / min for 30 minutes with a high-speed disperser, and then add 3.2 parts of toluene, 33.5 parts of luminous powder and 0.9 parts of additives are used for coloring and viscosity adjustment. The viscosity needs to be adjusted to 150±10s (coating -4 cups / 25°), and finally the impurities in it are filtered to obtain long-lasting luminous paint. Among them, the additives are luminous powder additives, defoaming agents and anti-settling agents. The particle size of the added luminous powder is about 10 μm, and the afterglow time is longer than 12 hours.

[0025] The main technical indicators of the luminous paint made by any of the above embodiments all reach the data shown in the table below:

Abstract

The invention discloses a long-acting luminous paint which is composed of the following components by mass: 40-60 parts of acrylic resin, 1-3 parts of bentonite, 10-12 parts of xylene, 2-4 parts of butyl acetate, 30-38 parts of luminous powder, and 0.5-2 parts of assistant. The invention also discloses a preparation method of the long-acting luminous paint, and the preparation method comprises the following steps: premixing the acrylic resin, bentonite, butyl acetate and xylene for high speed dispersion for 30 minutes, then stirring to adding toluene, the luminous powder and the assistant for adjusting color and viscosity, and finally filterring impurities to obtain the long-acting luminous paint. The prepared luminous paint has infinite times of luminous function.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a long-acting luminous paint and a preparation method thereof. Background technique [0002] Luminous paint is a kind of wall art paint. After absorbing general visible light and irradiating it for 10 to 20 minutes, it can continue to glow in the dark for about 12 hours. It can expand the limited monotonous plane into a fantastic multi-dimensional space that glows strangely. The decorative effect is radiant and well-proportioned, with lifelike patterns, clear layers, delicate, seamless, peeling, and cracking. The background color and complexion can be freely matched, and patterns such as figures, landscapes, flowers, and cartoons can be selected arbitrarily. It can be customized, and can be recycled infinitely. It has a long service life, is non-toxic and harmless, does not contain radioactive elements, has good adhesion to any substrate, and has excellent weather resistance. It is a new ...
