preparation example Construction

[0044] The present invention also provides the preparation method of above-mentioned a kind of MS-GPPS composite optical diffusion plate, comprises the steps:

[0045] (1) Automatically mix MS, frosted masterbatch, antioxidant and anti-aging agent according to the set ratio through the compounder to obtain compound A;

[0046] (2) GPPS, diffusion masterbatch, antioxidant and anti-aging agent are automatically mixed uniformly according to the set ratio by the compounding device, and compounded material B is obtained;

[0047] (3) Melting and extruding the compounding material A through an extrusion device to form a layer A material;

[0048] (4) Melting and extruding the compound B through an extrusion device to form a layer B material;

[0049] (5) The A-layer material and the B-layer material are distributed and stacked through a distributor, and then calendered by rolling equipment to obtain a MS-GPPS composite optical diffusion plate

[0050] Among them, the A-layer mater...

Abstract

The invention discloses an MS-GPPS composite optical diffusing plate. The MS-GPPS composite optical diffusing plate comprises the following components: MS, GPPS, frosted master batch and diffusion master batch. The optical diffusing plate with frosted texture, which is softer and more comfortable in light transmittance, is formed through compounding of the MS and GPPS and adding of the, frosted master batch and diffusion master batch; both the MS and GPPS have excellent processing fluidity and are easy for subsequent machine shaping; the MS has excellent compatibility with other resin materials, has good compounding effect with the GPPS, and is not easy in layer separation; after the frosted master batch is added, the plate can be directly machined and molded to be a lamp shade with frosted texture, is easy to mold, simplifies the technology, improves the yield, and is good in frosted effect and long in service life; in addition, the MS and GPPS are light and low in price, so that themanufacture cost and package and transportation costs of the plate are reduced, and the plate is economical and practical.
