Problems solved by technology

[0002] The existing optical plates used to make lampshades generally have the problems of poor heat resistance and poor impact resistance. In long-term use, the heat of the light source is likely to cause deformation of the lampshade due to heat, which affects the service life. During transportation, It is easy to be damaged by impact and cause defects. At the same time, the traditional frosted lampshade method is to sandblast the lampshade after the lampshade is formed to achieve the frosted effect. The process is cumbersome, the frosted effect is general, and the light diffusion effect is general

preparation example Construction

[0042] The present invention also provides a method for preparing the above-mentioned PETG-AS composite optical diffusion plate, comprising the following steps:

[0043](1) Automatically mix PETG, frosted masterbatch, antioxidant and anti-aging agent according to the set ratio through the compounder to obtain compound A;

[0044] (2) Automatically mix AS, diffusion masterbatch, antioxidant and anti-aging agent through the compounder according to the set ratio to obtain compound B;

[0045] (3) Melting and extruding the compounding material A through an extrusion device to form a layer A material;

[0046] (4) Melting and extruding the compound B through an extrusion device to form a layer B material;

[0047] (5) The A-layer material and the B-layer material are distributed and stacked by a distributor, and then calendered by rolling equipment to obtain a PETG-AS composite optical diffusion sheet.

[0048] Among them, the A-layer material and the B-layer material are distrib...

Abstract

The invention discloses a PETG-AS composite optical diffusion plate which comprises PETG, AS, matting masterbatch and diffusion masterbatch. The optical diffusion plate has matted texture and is moresoft and comfortable in light transmission is obtained by compositing two raw materials PETG and AS and adding the matting masterbatch and the diffusion masterbatch, AS has high temperature resistance, PETG has protruding toughness and high impact resistance, and performance of AS and performance of PETG are complementary, so that the plate is high in toughness, impact resistance and temperature resistance, thermal deformation temperature of the plate is up to 85-95 DEG C, the plate can be directly processed and shaped into a lamp cover with matted texture and is quite easy to form, process issimplified, yield is increased, matting effect is good, and service life is long; AS and PETG are nontoxic, environment-friendly and cheap in price, so that manufacturing cost is saved, and the plateis environment-friendly, economical and practical.
