Abstract

The invention relates to the technical field of plastic materials, and discloses a manufacturing process and a formulation of a mother-of-pearl paper. The mother-of-pearl paper is prepared from the following raw materials in parts by weight: 0.01%-3% of dispersing agent, 0.01%-3% of reinforcing agent, 1-3% of mica powder, 0.1%-1% of degrading agent, 40%-75% of shell powder and 28%-60% of PE. The shell powder is added to a plastic film as a calcium carbonate source, and compared with using ground stone as the calcium carbonate source for rich mineral paper, the waste shell powder is utilized, allowing for energy regeneration and saving of manufacturing cost; moreover, chitin in the shell powder has natural antibacterial activity, providing safer food packaging; the chitin in the shell powder is natural animal cellulose and can be uniformly dispersed together with the shell powder in polyethylene (PP) or polypropylene (PE) to replace partial C-C bonds, and after the chitin is decomposednaturally, adjacent carbon atoms are oxidated; therefore, the mother-of-pearl paper can be used as a plastic-reduced material just like the rich mineral paper, and also a degradable material, and is high in degradation rate and more environment-friendly than the rich mineral paper.

Description

technical field [0001] The invention relates to the technical field of plastic materials, in particular to a manufacturing process and formula of shell paper. Background technique [0002] Calcium carbonate is a commonly used plastic filler, which can increase the strength of plastic products and reduce costs. However, for plastic films, too much calcium carbonate will lead to film fragmentation, reduced toughness, poor film-forming properties, high technical difficulty and low cost-effectiveness, and is generally rarely added. However, in recent years, the awareness of environmental protection has increased, and the pollution of plastic film and plastic bags used for disposable packaging has led everyone to study how to reduce the plastic content (stone paper) in the plastic film. This technology uses shell powder to replace calcium carbonate. On the one hand, it turns waste into treasure, on the other hand, it increases the antibacterial ability and the degradation rate o...
