Abstract

The invention relates to an anti-yellowing energy-saving lamp adhesive and a preparation method thereof. The anti-yellowing energy-saving lamp adhesive comprises the following components in parts by weight: 270-330 parts of milk-white glue, 180-220 parts of inorganic filler, 0.5-2.5 parts of metal ion inhibitor, 1.5-5 parts of ultraviolet light absorbent and 0.75-2.5 parts of antioxidant. The prepared energy-saving lamp adhesive has the characteristics that an ultraviolet light absorbent, an antioxidant and a metal ion inhibitor are added at the same time and anti-yellowing property of the energy-saving lamp adhesive is obviously improved.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a yellowing-resistant energy-saving lamp adhesive and a preparation method thereof. Background technique [0002] Energy-saving lamps, also known as energy-saving bulbs, electronic bulbs, compact fluorescent lamps or integrated fluorescent lamps, refer to an integral lighting device that combines fluorescent lamps and ballasts. Compared with traditional lighting fixtures with low efficiency and high power consumption, energy-saving lamps are increasingly popular with consumers due to their high luminous efficiency, good color rendering, and long life, and have also been vigorously promoted and applied in China. The connection between the energy-saving lamp cap and the lamp tube mainly relies on adhesive bonding. The performance of the adhesive is an important factor affecting the quality of energy-saving lamps. Among them, yellowing resistance is an important indicator for ev...
