Embodiment Construction

[0020] In order to make it easy to understand the technical means, creative features, objectives and effects achieved by the present invention, the present invention will be further described in detail below in conjunction with examples of specific implementations.

[0021] a. Weigh the raw materials according to the weight ratio, 15g titanium dioxide, 10g pearl powder, 35g methyl methacrylate, 10g butyl methacrylate, 15g hydroxypropyl acrylate, 15g di-tert-amyl peroxide;

[0022] b. Stir the weighed titanium dioxide and pearl powder evenly and put it aside for later use;

[0023] c. Put methyl methacrylate, butyl methacrylate, and hydroxypropyl acrylate into the reactor for mixing and stirring. After mixing and stirring for 3 minutes, add di-tert-amyl peroxide to the reactor. Stir intermittently, and the dripping time is 2 hours;

[0024] c. After the di-tert-amyl peroxide is added dropwise, put the stirred titanium dioxide and pearl powder into the reaction kettle, stir well, stir e...

Abstract

The invention provides a directional reflective material and a preparation method thereof, and relates to the technical field of reflective materials. The directional reflective material is prepared by compressing a protective layer comprising the components of titanium dioxide, pearl powder, methyl methacrylate, butyl methacrylate, hydroxyl-propyl acrylate and di-tert-pentyl peroxide with a glass bead layer, a support layer and anti-sticking layer through a compacting machine. The reflective material provided by the invention is stronger in reflective degree, wider in reflected visibility, and better in corrosion resistance, can be little affected by climate change, and is suitable for more areas and use in various environments.

Description

Technical field [0001] The invention relates to the technical field of reflective materials, in particular to a directional reflective material and a preparation method thereof. Background technique [0002] Reflective materials are mainly used for the production of various reflective signs, vehicle number plates, safety facilities, etc. Its bright colors play an obvious warning role in the daytime, and its bright reflective effect can be used at night or under low light conditions. Effectively enhance people's recognition ability, see the target clearly, arouse alertness, so as to avoid accidents, reduce casualties, and reduce economic losses. It becomes an indispensable security guard for road traffic and has obvious social benefits. The scope of application is widely involved in public security, traffic supervision, fire protection, railways, coal mines and other departments. Civilian reflective materials are mainly reflective cloth, reflective lattice sheet, reflective printi...
