Acrylic material for mirror surface as well as preparation method and use method of acrylic material

Abstract

The invention relates to the technical field of high polymer materials, and in particular, relates to an acrylic material for a mirror surface as well as a preparation method and a use method of the acrylic material. The acrylic material for the mirror surface comprises 50%-60% of polymethyl methacrylate, 20%-30% of epoxy silane, 10%-15% of maleimide, 5%-6% of alpha-methacrylic acid, 0.1%-1% of an initiator and 0.2%-2% of a cross-linking agent, and has the advantages of high surface hardness and good surface flatness. The preparation method of the acrylic material can be used for effectively preparing the acrylic material with good flatness and hardness.

Description

technical field

[0001] The invention relates to the technical field of polymer materials, in particular to an acrylic material for a mirror surface, a preparation method and a use method thereof. Background technique

[0002] Acrylic, commonly known as plexiglass, can be divided into transparent boards, translucent boards and colored boards. It is known as "plastic crystal", and acrylic has the advantages of strong corrosion resistance and high strength, so acrylic is an excellent material for making furniture.

[0003] However, there are still shortcomings in the application of acrylic in furniture today: acrylic can be used as a better transparent plate, but when acrylic is used as a plate to prepare a mirror, due to the lack of hardness and smoothness of the surface, the prepared mirror is often There is a problem of mirror deformation, which does not meet the requirements of high-end places for mirror acrylic panels.
