experiment example 1

[0048] Preparation of matting agent masterbatch: mix calcium carbonate powder and talcum powder 3000H and stir evenly to form a mixture. The consumption ratio of calcium carbonate powder and talcum powder 3000H is recorded in table two. Using a twin-screw extruder (model: PSM50, manufacturer: Hongyu Machinery Co., Ltd.), the above mixture is mixed with PET polyester pellets (model: CB600H, manufacturer: Far Eastern New Century Company) to prepare matting agent master grain.

[0049] Preparation of low-gloss boards: use a multi-layer board pressing machine (model: CL38879, manufacturer: Dingfeng Automation Co., Ltd.) to prepare matting agent masterbatches and PET into low-gloss boards. The low-gloss plate includes a base material and a low-gloss layer formed on the base material. The substrate comprises PET, and the low gloss layer comprises PET and a matting agent dispersed in PET. Using a scanning electron microscope (brand: JEOL, model: JSM-6390LV), it was found that the ...

Abstract

The present disclosure provides a low gloss sheet and a matte product prepared therefrom. The low gloss sheet includes a substrate and a low gloss layer disposed thereon. The low gloss layer includespolyester and a matting agent. A weight percentage of the matting agent is 4 wt % to 10 wt % based on the total weight of the low gloss layer. The matting agent includes a plurality of first particlesand a plurality of second particles. An average particle diameter (d50) of the first particles and the second particles is 8 to 10 [mu]m and 3 to 6 [mu]m respectively. Oil absorption of the second particles is 30 to 100 ml / 100 g. The matte product is prepared from the low gloss sheet by a forming technique. The low gloss sheet and molded product have low surface gloss, and multiple functions suchas a package material.

Description

technical field [0001] The invention relates to a low-gloss board and molded products made from it. Background technique [0002] Polyester sheets are widely used in various industries, such as packaging materials for products. If the surface of the packaging material is in a low gloss state, the appearance and texture of the packaging material can be increased. However, the surface gloss of general polyester sheets is quite high, so it is difficult to meet the high texture requirements of packaging materials. Therefore, there is an urgent need for a polyester sheet with a low-gloss surface, especially a polyester sheet that can still maintain a good low-gloss surface after heating and stretching. Contents of the invention [0003] The invention provides a low-gloss board. The low-gloss board includes a base material and a low-gloss layer formed on the base material. The low gloss layer includes polyester and a matting agent. The weight percentage of the matting agent...
