Problems solved by technology

In China, the black oil of the ink-coated LED base is mainly made of two-component ink. The two-component ink is mainly composed of a film-forming substance and a curing agent. After the ink is prepared, it must be used under the specified time and conditions. , the ink will solidify and deteriorate, and can no longer be used
It has the following unresolved problems: 1. The two-component ink needs to add an amine curing agent, which has a strong smell and is harmful to the health of construction workers; 2. The storage time is short, and the storage time of the ink after adding the curing agent is 2- 4 hours, it is easy to cause waste of ink; 3. After adding the curing agent, it must be baked, which consumes electricity and increases the cost; 4. After adding the curing agent, it is easy to corrode the screen plate, and the service life of the screen plate is shortened

Abstract

The invention discloses single-component high-covering-property ink and a preparation method thereof and relates to the technical field of ink. The ink is prepared by using the following components in parts by weight: 51-61 parts of resin, 8-15 parts of solvent, 12-16 parts of adhesive force accelerator, 7-9 parts of pigment, 2-4 part of filler and 5-9 parts of assistant, wherein the assistant comprises thickener, delustering agent, wear-resistant anti-scratching agent, oil repellent, defoaming agent, dispersing agent and essence. The resin adopted by the invention is single-component resin, the chlorine content is low, the resin does not react with AB epoxy glue at high temperature of 120-150DEG C, yellowing which influences the brightness of an LED (Light Emitting Diode) lamp is not caused, the alcohol resisting performance is good, the printing adaptability is high, the production efficiency can be improved and the personal harm to construction personnel can be reduced.

Description

technical field [0001] The invention belongs to the technical field of ink, and in particular relates to a single-component high-covering ink and a preparation method thereof. Background technique [0002] Coating the LED base with black ink can increase the shading performance of the base and improve the brightness of the LED lamp. Because LEDs are widely used, but they are small in size and have many processes, the performance requirements of the ink used on the LED base are required. very high. In China, the black oil of the ink-coated LED base is mainly made of two-component ink. The two-component ink is mainly composed of a film-forming substance and a curing agent. After the ink is prepared, it must be used under the specified time and conditions. , the ink is solidified and deteriorated, and can no longer be used. It has the following unresolved problems: 1. The two-component ink needs to add an amine curing agent, which has a strong smell and is harmful to the heal...
