Abstract

The invention relates to the technical field of anti-explosion paint, and discloses water-borne anti-explosion paint and a preparing method and application thereof. The water-borne anti-explosion paint prepared from epoxy modified water-borne polyurethane, an aid and water in specific ratio in cooperation has good water tolerance and tensile strength and also has good adhesive force to glass, a coating prepared from the paint is high in mechanical strength, the after-falling explosion of an LED lamp is effectively prevented, and therefore it is avoided that a non-insulated electric part or inner wire can be touched or the mechanical insulation of parts in a device is damaged, the harm of glass fragments to human is effectively avoided, and the potential safety hazards of the LED lamp in use are reduced to the maximum extent. Water is used as a solvent, cost is low, no VOC pollution is generated, and the paint is safe, environmentally friendly and free of peculiar smell.

Description

Technical field [0001] The invention relates to the technical field of explosion-proof coatings, in particular to a water-based explosion-proof coating and a preparation method and application thereof. Background technique [0002] In recent years, the rapid development of semiconductor lighting technology has highlighted its application prospects. Traditional indoor lighting systems can hardly meet people's dual needs for lighting comfort and green energy saving. Using LED as a lighting source to replace traditional light sources has many advantages such as low power consumption, prolonged lighting system life, green and environmental protection, and greater design flexibility, and has become a hot research topic in the field of semiconductor lighting. The lampshade materials of LED lamps are mainly made of plastic and glass, especially the popular LED filament lamps in recent years, which are close to incandescent lamps and all adopt glass shells. However, when this type of LE...
