Abstract

The invention relates to a film based on nano calcium carbonate and a preparation process and device thereof, the film comprises a base layer, wherein the inner side and the outer side of the base layer are respectively provided with a bonding layer and a protective layer, and the thickness ratio of the bonding layer to the base layer to the protective layer is (2-2.5):7:(1-1.5); the base layer comprises the following components in parts by weight: 20-30 parts of nano calcium carbonate, 20-30 parts of an ethylene-butylene copolymer, 5-10 parts of dimethylacetamide, 2-5 parts of a cross-linking agent and 2-5 parts of a modifier; the bonding layer comprises 20-30 parts of a propylene-butylene copolymer, 5-10 parts of nano calcium carbonate, 3-5 parts of glycerol monostearate, 3-5 parts of fatty alcohol polyether amide, 1-2 parts of a cross-linking agent and 1-2 parts of a modifier; and the protective layer comprises 20-30 parts of an ethylene-propylene copolymer, 20-30 parts of homo-polypropylene, 5-10 parts of nano calcium carbonate, 1-3 parts of a cross-linking agent and 1-3 parts of a modifier. The film is high in quality, good in flexibility and large in tensile strength, and the film prepared through the device designed by the invention is stable and smooth in forming, high in production quality and high in qualified yield.

Description

technical field [0001] The invention belongs to the technical field of nanoscale new materials, and provides a film based on nanometer calcium carbonate and its preparation process and device. Background technique [0002] Nano-calcium carbonate is also known as ultra-fine calcium carbonate and ultra-fine calcium carbonate. Due to the superfineness of calcium carbonate particles, its crystal structure and surface electronic structure change, resulting in quantum size effect, small size effect, surface effect and macroscopic quantum effect that ordinary calcium carbonate does not have, and the particle size is fine and uniform, Narrow distribution, large specific surface area, good surface activity and dispersibility, and high surface energy make it reflect more excellent properties that many ordinary calcium carbonate materials do not have in actual use. Nano-calcium carbonate has applications in the film industry, which can improve the rheology of the film masterbatch, imp...
