Abstract

The invention relates to a novel reflective coating material, which is prepared from the following raw materials in parts by weight: hydroxyethyl cellulose, elastic acrylic emulsion, silicone acrylic emulsion, urea formaldehyde resin , nano titanium dioxide, water, a dispersing agent, a pH regulator, titanium dioxide, a leveling agent, barium sulfate, mica powder, heavy calcium carbonate, acrylic emulsion, a thickening agent and a film forming aid pigment. The invention further provides a preparation method of the novel reflective coating material. The novel reflective coating material has good lightness, light reflectivity, high temperature resistance, yellowing resistance and hardness, is high in adhesive force, can still keep high reflective rate after being used for a long time, is not prone to discoloring under the high-temperature condition, and can be applied to the fields of illumination, exterior walls and the like.

Description

technical field [0001] The invention relates to the field of paint production, in particular to a novel reflective paint and a preparation method. Background technique [0002] At present, reflective coatings are widely used in the fields of light distribution devices and LEDs, such as light sources and lamps. high brightness, but it also causes a serious problem, that is, light source pollution. The highly concentrated light source directly pierces people's eyes, affects the comfort of indoor people, and has certain damage to the human body, so it is favored by many consumers. complain. [0003] Diffuse reflection refers to the phenomenon that light is randomly reflected in all directions by a rough surface. When light shines on the surface of an object, if the surface of the object is an ideal flat surface, except for the luminous flux absorbed by the object, other luminous fluxes are reflected by this ideal plane, which is called total reflection or pure reflection. ...
