Preparation method of high temperature-resistant diffuse reflection paint for lamps

Abstract

A preparation method of a high temperature-resistant diffuse reflection paint for lamps is provided. The method comprises the following steps: 1, weighing the following materials, by weight, 30 parts of an acrylic resin, 20-30 parts of an aqueous solution of siloxane, 8 parts of glycerin, 20 parts of acrylic acid, 20 parts of alumina, 13-15 parts of 8% zinc naphthenate, 20 parts of titanium dioxide, 2-6 parts of calcium fluoride and 15 parts of sodium hexametaphosphate; and 2, mixing the materials, and carrying out constant temperature stirring on the materials at 75DEG C for 3-4h. The method provided in the invention has the advantages of simple preparation technology, easy realization, and high production efficiency; and the paint provided in the invention, which has good mechanical performances and a good adhesion and can be coated on various lamps, has the advantages of high temperature resistance, realization of high reflection rate maintaining after lasting a high temperature for 24h, and simple preparation technology.

Description

technical field [0001] The invention relates to a preparation method of a high temperature resistant diffuse reflection coating for a lamp. Background technique [0002] LED energy-saving lamps are the most commonly used lamps in our daily life, but the irradiation angle of LED energy-saving lamps is limited, which can only be about one-third of that of ordinary lamps, while LED lamps can only have high brightness in a narrow angle , so now the common method is to expand the irradiation surface by using diffuse reflection coating, but the existing coating not only has low diffuse reflectance, but also is easy to be baked at high temperature, and the reflectance decreases or disappears. Contents of the invention [0003] The object of the present invention is to provide a preparation method of a high temperature resistant diffuse reflective coating for lamps. [0004] In order to achieve the above object, the present invention adopts the following technical scheme: a pr...
