Abstract

The invention relates to a preparation method of a high-brightness wide-angle reflecting material, and belongs to the technical field of reflecting materials. According to the method, glass beads arecovered by a heterogeneous precipitation method, the high-brightness wide-angle reflecting material is prepared, a titanium dioxide thin film wraps the surfaces of the glass beads, the reflecting rateof the surfaces of the glass beads is improved, incidence light penetrates a crystal boundary through a short journey to reach the surfaces of the glass beads to generate retro-reflection is generated through refraction and reflection, a high visual effects are generated, the titanium dioxide wraps the glass beads, the reflecting rate of the surfaces of the glass beads is increased, light intensity is improved, and high visual induction is provided for people. The high-brightness wide-angle reflecting material is prepared by combining a bead spreading method and multiple processing methods, the exposed reflecting material is prepared by the bead spreading method, one layer of polymethyl methacrylate is sprayed, so that the glass beads are firmly combined on the base cloth, falling is omitted, so that the prepared high-brightness wide-angle reflecting material is good in rubbing resistance.

Description

technical field [0001] The invention relates to a preparation method of a high-brightness wide-angle reflective material, which belongs to the technical field of reflective materials. Background technique [0002] With the development of society and the advancement of science and technology, more and more vehicles are running on the road. In the face of all kinds of vehicles, sanitation vehicles have their special uses. They are operated on the road, and there are many vehicles on the road. Especially It is the eye-catching color of the vehicle when working in the early morning or at night, which will also affect its safety. The outer shell of the existing sanitation vehicle is mainly treated with ordinary paint, which is not bright enough. Its safety is also reduced. The existing paint generally only considers its anti-corrosion and durability; it does not take into account the special use of its reflective properties. If necessary, it is coated with a layer of anti-corrosi...
