Description

Technical Field

[0001] This invention belongs to the field of acrylic paint technology, specifically relating to a UV-resistant acrylic painting paint and its preparation method. Background Technology

[0002] Acrylic paint is a synthetic polymer pigment, generally made by mixing pigment powder with acrylic emulsion. During synthesis, different colors of pigment powder can be selected and mixed with acrylic emulsion according to needs to obtain different colors of painting paint.

[0003] However, since acrylic paints are generally made by mixing pigment powder with acrylic emulsion, and acrylic emulsion has good water resistance, alkali resistance and stain resistance, but because acrylic emulsion is an emulsion, it is not suitable for use in sunny outdoor places. It cannot be used in some outdoor places or in sunny glass sunrooms, which limits the scope of use of acrylic paints. Summary of the Invention

[0004] The purpose of this invention is to provide a UV-resistant acrylic paint and its preparation method in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] This invention provides a UV-resistant acrylic paint, comprising the following components in parts by weight:

[0007] 15-30 parts color powder;

[0008] 20-30 parts acrylic emulsion;

[0009] 45-65 parts sunscreen;

[0010] 6-12 doses of delay agent;

[0011] 80-100 parts pure water;

[0012] 25-30 parts of 75% ethanol solution;

[0013] The sunscreen agent is a mixture of coniferyl alcohol, sinigrin and salicumin.

[0014] As a further optimization of the present invention, the raw materials for preparing the sunscreen agent include 20-30 parts of coniferyl alcohol, 5-12 parts of sinigrin and 8-16 parts of salicumin by weight.

[0015] As a further optimization of the present invention, the preparation process of the sunscreen agent is as follows: weigh coniferyl alcohol, sinigrin and salicumin according to the weight ratio, place them in a mixer, stir at 80-95 r / min for 5-8 min, and then perform ultrasonic treatment for 20-30 min to obtain the sunscreen agent.

[0016] As a further optimization of the present invention, the retardant is composed of a mixture of caffeic acid, eugenol and propolis.

[0017] As a further optimization of the present invention, the mass ratio of caffeic acid, eugenol and propolis is 1:1:(2-4).

[0018] As a further optimization of the present invention, the propolis is composed of a mixture of gum arabic, beeswax, glycerin and pollen, wherein the mass ratio of gum arabic, beeswax, glycerin and pollen is 5:3:1:0.5.

[0019] This invention also provides a method for preparing UV-resistant acrylic paint, comprising the following steps:

[0020] S1, by weight, take acrylic emulsion and place it in a container, add sunscreen and retardant, stir until evenly mixed, and obtain the base material;

[0021] S2, add pure water and 75% ethanol solution to the base material, stir until evenly mixed, then add color powder, stir at 80-95 r / min for 5-8 min to obtain acrylic painting pigment.

[0022] The beneficial effects of this invention are as follows: by adding sinigrin and apigenin to acrylic paint, they can work synergistically. Apicagenin increases the water solubility and fat solubility of sinigrin. The preparation of both in acrylic paint also increases the antioxidant properties of acrylic paint, thereby achieving a sun protection effect. It can resist ultraviolet rays in sunlight, so that acrylic paint can be used not only indoors, but also outdoors in places where the sun is in direct sunlight, making its application range wider.

[0023] Furthermore, a retarder was added to the acrylic paint. When the retarder is mixed with the sunscreen, it can better delay oxidation. The propolis used can increase the adhesion between the acrylic paint and the graffiti paper, making the acrylic paint less likely to fall off. Detailed Implementation

[0080] Performance testing

[0081] The performance of the acrylic paints prepared in Examples 1-3 and Comparative Examples 1-6 was verified as follows:

[0082] ① Photoresistance test (photostable test): The acrylic paints prepared in Examples 1-3 and Comparative Examples 1-6 were applied to graffiti paper. The color density changes of the graffiti paper after 3 days and 28 days of exposure to ultraviolet light after spraying were detected by Q-SUN weather resistance tester and X-RITE color density meter before and after 800 hours of Q-SUN exposure (evaluation criteria: A: less than 10%; B: 10-30%; C: 30-50%; D: 50-70%) (UVB medium-wave ultraviolet light with a wavelength of 290-320nm was used).

[0083] The results are shown in the table below:

[0084]

[0085]

[0086] The comparison shows that, in Examples 1-3, the acrylic paints prepared in Examples 2 and 3 were tested after being applied to graffiti paper and left to stand for 3 days. The test results were the same, showing that they all had good sun protection. However, the acrylic paint prepared in Example 1 was slightly inferior to that in Examples 2 and 3 when it was applied to graffiti paper and left to stand for 3 days.

[0087] The acrylic paints prepared in Examples 1-3 were applied to graffiti paper and left to stand for 28 days before being tested. Example 3 was slightly inferior to Example 2. Therefore, it was concluded that the acrylic paint prepared in Example 2 had the best effect.

[0088] Example 1, which has the worst sun protection effect among the examples, is compared with Comparative Examples 1-6. The sun protection effect of Comparative Examples 1-6 is not as good as that of Example 1. Therefore, Example 2 is the optimal solution of the present invention, which is less likely to fade during use.

[0089] ②Observe whether the acrylic paints exhibited cracking and peeling areas after being irradiated under ultraviolet light for 28 days and then under Q-SUN light for 800 hours. The results are shown in the table below:

[0090]

[0091]

[0092] Observations show that Example 2 has the best effect with a cracked area of ​​5%, and it is not easy to separate from the graffiti paper. It has good UV resistance and can be used in places with plenty of sunlight.

[0093] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
