Problems solved by technology

However, the surface of the traditional silver-coated reflective shading cloth is coated with shading and reflective coatings that contain volatile organic compounds. After the volatile organic compounds are exposed to sunlight, they will emit pungent odors. These odors often contain formaldehyde, etc. Hazardous substances, especially in a confined space, are difficult to distribute, and will cause harm to the human body after inhalation
Moreover, this traditional coating will produce a large amount of waste gas and waste water in the production process, emit pungent odor, pollute the environment and threaten people's health

Embodiment 1

[0022] This UV reflective paint is made of the following components by weight (in terms of 100 kilograms, the same below):

[0023]

[0024] The preparation method of the UV reflective coating adopts the following steps: first, stir and mix the light-reflecting agent, acrylate resin and photoinitiator to obtain a mixture; 35°C, stir in a high-speed disperser at a speed of 800-1000rpm for 20-30 minutes, then add defoamer, stir for 10-15 minutes and keep warm for 1.5-2 hours to disperse the mixture into a stable emulsion to obtain the UV reflective coating.

[0025] Application of the UV reflective coating: Spray the UV reflective coating evenly on the surface of the clean shading cloth substrate with a spray thickness of 10-30 μm, and then irradiate the shading cloth substrate sprayed with the UV reflective coating under a UV lamp with a main peak of 420nm 2-6s on the surface, the UV reflective coating can be cured, and the irradiation energy of the UV lamp is 295mw / cm 2 a...

Embodiment 2

[0027] The UV reflective coating is made of the following components by weight:

[0028]

[0029] The preparation method and application are the same as in Example 1.

Embodiment 3

[0031] The UV reflective coating is made of the following components by weight:

[0032]

[0033]

[0034] The preparation method and application are the same as in Example 1.

[0035] The reflective powder described in Examples 1-3 was purchased from Huizhou Yingguang Plastic Pigment Co., Ltd., the multifunctional acrylate monomer with a functionality of 2-3 was purchased from Shuishan Polymer Company, and the CARE73 silicon-based additive was purchased from Seiko Ink (Hangzhou) Co., Ltd.

Abstract

The invention discloses a UV reflective paint, and a preparation method and application thereof, belonging to the technical field of paint. The UV reflective paint is prepared from, by weight, 40 to 50% of a reflective agent, 25 to 35% of a silver solvent, 8 to 10% of an active diluent, 10 to 15% of acrylate resin, 3 to 5% of a photoinitiator and 2 to 5% of an antifoaming agent. The UV reflective paint contains no volatile organic compound and does not give off harmful gas in the process of both production and usage; after curing, the UV reflective paint has better sun-shading and reflection effect, and sunlight reflectivity is 90% or above; after being cured by ultraviolet rays, the paint can firmly adhere on the surface of a shading cloth matrix and has heat resistance, cold resistance, ageing resistance, rain resistance, moisture resistance, good toughness, high tensile strength and high impact strength; and through usage of ultraviolet curing technology, the UV reflective paint immediately undergoes a cross-linking reaction, energy conservation and high efficiency are realized, exhaust gas and waste water are not produced, and environmental friendliness is realized.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a UV reflective coating and a preparation method and application thereof. Background technique [0002] Sunshade fabrics are widely used in homes, hotels, schools, automobiles and other places, especially the silver-coated reflective sunshade fabrics with the function of reflecting sunlight, because they can reflect more than 80% of sunlight, and achieve good performance in hot summer. Excellent heat insulation and shading effect, so it is more popular. However, the surface of the traditional silver-coated reflective shading cloth is coated with shading and reflective coatings that contain volatile organic compounds. After the volatile organic compounds are exposed to sunlight, they will emit pungent odors. These odors often contain formaldehyde, etc. Harmful substances, especially in a confined space, are difficult to distribute, and will cause harm to the human bo...
