Problems solved by technology

[0006] At present, the luminous paint on the market is mainly sold directly in barrels, with many construction steps, high requirements for construction personnel, and relatively difficult construction; the aerosol-type luminous paint with luminous effect is easy to construct, easy to carry, and has an extremely superior market Prospects, but no luminous aerosol paint products have been found in the domestic market. There are a small number of luminous aerosol paint products abroad, but basically there are problems such as short luminous time, easy precipitation, and clogged nozzles, which affect the construction effect and construction mentality. It has a serious impact on the promotion and development of luminous aerosol paint

Abstract

The noctilucent aerosol paint is prepared from the following components in parts by weight: 28 to 40 parts of mixed modified acrylic resin, 10 to 15 parts of silicone acrylic resin, 10 to 20 parts of environment-friendly solvent, 4.5 to 10 parts of bentonite, 12 to 24 parts of noctilucent powder, 1.5 to 4 parts of nano graphite powder, 0.5 to 2.5 parts of silane coupling agent, 0.2 to 1 part of flatting agent, 0.3 to 1 part of defoaming agent, 2 to 4 parts of total reflection glass beads of 150 to 500 meshes and 15 to 27 parts of environment-friendly propellant. The noctilucent powder adopting the technical scheme has the advantages that the noctilucent powder is high in light absorbing and releasing efficiency and good in noctilucent performance; the formula is optimized, the solid content is high, and the hardness and the adhesive force performance are excellent; aerial fog packaging and storage stability are achieved, use is safe and convenient, and construction efficiency is high; and the paint is environment-friendly and low in VOC. The invention also discloses a preparation method of the noctilucent aerosol paint.

Description

technical field [0001] The invention belongs to the technical field of aerosol products, in particular to a luminous aerosol paint and a preparation method thereof. Background technique [0002] Aerosol paint (Spray Paint), also known as automatic spray paint or hand-crank automatic paint. Aerosol paint is a product in the form of self-pressurized packaging in which resins, solvents, pigments, fillers, propellants, etc. are put into aerosol cans, and controlled by a valve release device, so that the mixture is sprayed in the form of aerosol. [0003] Aerosol paint has the characteristics of flexible and simple construction operation, easy to carry, good spraying atomization effect and high spray rate. It breaks the construction method of traditional paint and easily solves the difficult problem of traditional paint in indoor and outdoor construction. Aerosol paint has won the favor of consumers for its convenience, reliability and economy. In recent years, the market demand...
