Problems solved by technology

First of all, due to the need for uninterrupted 24-hour lighting in the dark environment of the tunnel, the power consumption of lighting in operation and management is large, and the cost is high. As a result, many units cannot afford the operation and maintenance costs of the tunnel. Turn on the designed lighting fixtures, resulting in insufficient road lighting brightness for road tunnel operation, which brings difficulties to safe driving; secondly, due to changes in light intensity at the entrance and exit sections of the tunnel, "black holes" and "white holes" are prone to appear , causing hidden dangers to drivers and drivers; third, with the increase of the tunnel mileage, the exhaust gas content in the tunnel increases, and the air in the tunnel needs to be replaced through the exhaust system. The exhaust system has high operating costs and the exhaust effect not good

Abstract

The invention provides a negative ion water-based paint with a fireproof function. The negative ion water-based paint is prepared from the following components in parts by weight: 35-38 parts of water-based polyurea resin, 12-18 parts of water-based fluorocarbon resin, 8-10 parts of water-based vinyl chloride-vinyl acetate resin, 18-22 parts of a functional material, 5-8 parts of a flame retardant, 8-10 parts of an auxiliary agent and 50-60 parts of water, wherein the functional material is obtained by coating nano rare earth aluminate, nano negative ion powder and nano titanium dioxide with a water-based organic material, so that the stability and the dispersity of the functional material in a system as well as the luminescence property and the negative ion property of the coating can be improved. The negative ion water-based paint with the fireproof function, provided by the invention, is used for a tunnel, so that the interior of the tunnel can be continuously illuminated, the design illumination operation cost is saved, and the water-based paint contains a nano negative ion component and nano titanium dioxide, so that air in the tunnel can be effectively purified, and a coating has antibacterial and mildew-proof characteristics; and the operation cost of the exhaust system is reduced. The invention also provides a preparation method of the multifunctional water-based paint for the tunnel.

Description

technical field [0001] The invention relates to the technical field of water-based coatings, in particular to a negative-ion water-based coating with a fireproof function and a preparation method thereof. Background technique [0002] With the rapid development of my country's transportation and highway construction, the construction of highway tunnels is in the ascendant. While a large number of tunnel constructions bring convenience to people's transportation, many management problems have also been exposed in the operation stage. First of all, due to the need for uninterrupted 24-hour lighting in the dark environment of the tunnel, the power consumption of lighting in operation and management is large, and the cost is high. As a result, many units cannot afford the operation and maintenance costs of the tunnel. Turn on the designed lighting fixtures, resulting in insufficient road lighting brightness for road tunnel operation, which brings difficulties to safe driving; se...
