Description
Technical Field
The invention relates to a deep blue LED pouring sealant color paste and a preparation method thereof, and application of the deep blue LED pouring sealant color paste in the LED pouring sealant color mixing field, in particular application in the LED infrared receiving tube pouring sealant color mixing field.
Background
With the rapid development of the LED packaging industry, the demand for the diversity of the products of the LED potting adhesive is increasing, wherein the lamp beads used in the signal lamp field need to be made into various colors, and the special LED products such as the lamp beads of the infrared receiving diode need to filter most visible light, so as to reduce the signal interference.
The color matching method of the existing LED pouring sealant mainly comprises the steps of weighing one or more toners, directly adding the toners into the LED pouring sealant, heating, mixing and uniformly stirring the toners, and then using the toners in the pouring sealant. For 1kg of LED pouring sealant, the mass of the added toner is only 0.01-0.50 g each time, the weighing is usually required to be accurate to one ten thousandth of gram, the weighing accuracy of the toner directly influences the color difference of LED lamp beads, the weighing is very inconvenient, color matching operation among different batches inevitably causes the defects of color difference and the like of the LED lamp beads among different batches; in the process of adding the toner, the toner dust scatters everywhere, and environmental pollution of a production workshop is easily caused.
Disclosure of Invention
The invention aims to provide a dark blue LED pouring sealant color paste aiming at the defects of inconvenient toner weighing, color difference of LED lamp bead appearance, workshop environmental pollution and the like in the prior color matching technology, so as to improve the accuracy and convenience of LED pouring sealant color matching, reduce the workshop environmental pollution, improve the color consistency of lamp beads in different batches and effectively avoid the color difference of the lamp bead appearance.
The purpose of the invention is realized by the following technical scheme:
a dark blue LED pouring sealant color paste is prepared by mixing a basic color paste A and a basic color paste B according to the weight ratio of 1: 0.5-5; the basic color paste A comprises the following components in parts by weight: 10-20 parts of epoxy resin, 1-5 parts of GS green powder and 0.1-0.5 part of matting powder; the basic color paste B comprises the following components in parts by weight: 10-20 parts of epoxy resin, 1-5 parts of FN violet-blue toner and 0.1-0.5 part of color paste stabilizer.
Preferably, the basic color paste A comprises the following components in parts by weight: 10-12 parts of epoxy resin, 1-2 parts of GS green powder and 0.1-0.2 part of matting powder; the basic color paste B comprises the following components in parts by weight: 10-12 parts of epoxy resin, 1-2 parts of FN violet-blue toner and 0.1-0.2 part of color paste stabilizer.
The epoxy resin is at least one of bisphenol A epoxy resin, bisphenol F epoxy resin, hydrogenated bisphenol A epoxy resin and alicyclic epoxy resin. The epoxy equivalent of the epoxy resin is matched with that of the LED pouring sealant, and preferably at least one of bisphenol A epoxy resin, bisphenol F epoxy resin, hydrogenated bisphenol A epoxy resin and alicyclic epoxy resin with the epoxy equivalent of 110-200. Epoxy equivalent means grams of epoxy resin containing one equivalent of epoxy groups.
The GS green powder is weak acid green GS.
The matting powder is used for reducing the glossiness of the color paste and is at least one of calcium carbonate, cellulose acetate and silicon dioxide.
The FN purple blue toner: pigment blue 15: 2.
The color paste stabilizer is at least one of phenyl ortho-hydroxybenzoate, 2- (2 '-hydroxy-5' -methylphenyl) benzotriazole, 2, 4-dihydroxy benzophenone and 2-hydroxy-4-n-octoxy benzophenone, and is used for ensuring the color stability of the color paste and the color stability of the finally produced LED lamp bead.
The invention also aims to provide a preparation method of the dark blue LED pouring sealant color paste, which comprises the following steps: weighing the components according to the formula; mixing and uniformly stirring epoxy resin, GS (yellow-green) toner and flatting powder at the temperature of 20-90 ℃ to obtain basic color paste A; mixing and uniformly stirring epoxy resin, FN (FN) violet-blue powder and a color paste stabilizer at 20-90 ℃ to obtain a basic color paste B; and weighing the basic color paste A and the basic color paste B according to the formula, mixing and uniformly stirring at 20-90 ℃ to obtain the deep blue LED pouring sealant color paste.
Preferably, the temperature range during mixing and stirring is 70-80 ℃. When the temperature is lower than the above temperature, the viscosity of the epoxy resin is high, and the materials are not easy to disperse uniformly; above this temperature, the epoxy resin is prone to yellowing, which affects the color consistency of the color paste.
The invention also aims to provide application of the deep blue LED pouring sealant color paste in the LED pouring sealant color mixing field, in particular application in the LED infrared receiving tube pouring sealant color mixing field, wherein the weight ratio of the deep blue LED pouring sealant color paste to the LED pouring sealant is 1-3: 199-197, and when the deep blue LED pouring sealant color paste is used for color mixing of the LED infrared receiving tube pouring sealant, most visible light can be filtered, and stray light signal interference is reduced.
Compared with the prior art, the invention has the beneficial effects that:
the color paste is prepared from the toner and used for the color matching process of the LED packaging adhesive, so that the accuracy and convenience of the color matching of the LED packaging adhesive are improved, and the dust pollution of a production workshop is reduced; the consistency of the appearance color of the lamp beads is improved, and the color difference of the appearances of the LED lamp beads in different batches is avoided. Meanwhile, the extinction powder and the color paste stabilizer are added in the color paste preparation process, so that the color paste stability and the color stability of the appearance of the LED lamp bead are improved.
