Abstract

The invention relates to a preparation method of an adhesive for an energy-saving lamp tube. The method comprises the steps of dissolving dry powdered alumina in water, and stirring evenly to obtain a solution A; dissolving aluminum nitrate in methanol, and carrying out heating and full stirring to obtain a solution B; and heating and stirring the solution A and the solution B to obtain the product. The product prepared by the method provided by the invention has the advantages of less use amount, good adhesion with coats, possessing of no influences on visible light permeation and so on, has simple processes, is suitable for mass production, and has the prospect of a wide market application.

Description

technical field [0001] The invention relates to a preparation method of an adhesive for an energy-saving lamp tube. Background technique [0002] The performance of energy-saving lamps is closely related to the quality of phosphors and their coatings. The quality of the phosphor coating directly affects the appearance of the lamp, and also has a major impact on the light color parameters and lumen maintenance rate of the lamp. When the powder layer is too thin, the ultraviolet radiation is not fully utilized by the powder layer; and when the powder layer is too thick, the visible light generated by excitation is absorbed too much by the powder layer. When coating the tube, the fluorescent powder is stuck on the glass tube by the adhesive, after the tube is baked, the adhesive is baked off, and the fluorescent powder is stuck on the glass tube by the adhesive. Therefore, the quality of the adhesive directly affects the thickness of the coating, which leads to the performa...
