Problems solved by technology

[0002] With the development of logistics, and the deep-rooted reasons such as the lag of China's highway construction, in order to improve the interest rate of the highway, the number of traffic and pedestrians at night is increasing. The reflective layer of street lamps currently on the market is composed of topcoat and primer. The top coat is a reflective coating, mainly solvent-based polyurethane coating. The solvent-based polyurethane coating film has the characteristics of high hardness, strong adhesion, high wear resistance and good solvent resistance, but its reflective rate is 60%, which is relatively low. Poor, easily lead to the occurrence of accidents at night; and solvent-based coatings are poor in environmental protection, so in order to continuously improve the reflective effect of street lamps, ensure the safety of driving and pedestrians, and improve environmental protection, the present invention has studied a reflective coating for led street lamps and its Preparation

Abstract

The invention discloses a reflective paint for a led street lamp. The reflective paint is prepared from the following raw materials in parts by weight: 1-2 parts of 2-mercaptobenzimidazole, 5-7 parts of mannitol, 2-3 parts of alkylated diphenylamine, 6-8 hollow glass beads, 2-3 parts of tetrakis hydroxymethyl phosphonium sulfate, 1-2 parts of dodecyl trimethoxysilane, 4-6 parts of methylcellulose, 130-150 parts of 4-chloromethyl styrene, 16-20 parts of aluminum isopropoxide, 3-4 parts of reflective powder, 27-30 parts of 10-12% hydrogen peroxide solution, 3-4 parts of inositol hexaphosphate, 1-2 parts of stannous sulfide, 10-15 parts of nanometer titania, 7-9 parts of chlorinated paraffin and 4-6 parts of dicumyl peroxide. The reflective powder is taken as a reflective assistant, so that the reflective paint has a good reflective effect, and the obtained coating is good in tenacity, high in cohesiveness on the surface of a street lamp shade, high in peel strength, environment-friendly and free of pollution.
