Problems solved by technology

However, since the purification of these biopolymers usually requires complex chemical processes, and the plasticity of general biopolymers is poor, it is difficult for the prepared materials to be comparable to the current polymer plastics.

Abstract

The invention discloses a preparation method of ionic mineral plastics, comprising: (1) molecularly modifying polyvinyl alcohol solution with sodium alginate solution to obtain polyvinyl alcohol linear polymer solution modified with alginic acid; (2) adding phosphoric acid Calcium ion oligomers are added to the alginic acid-modified polyvinyl alcohol linear polymer solution, and after stirring evenly, the obtained emulsion is centrifuged to obtain the precursor gel of ionic mineral plastics; (3) the precursor of ionic mineral plastics Ionic mineral plastics are obtained from the gel through plastic molding or natural drying. The invention also discloses the ionic mineral plastic obtained by the above preparation method and its application. The ion mineral plastic prepared by the invention can be used as a completely degradable plastic.

Description

technical field [0001] The invention belongs to the technical field of degradable plastics, in particular to a preparation method of ionic mineral plastics and its products and applications. Background technique [0002] Plastics (from the Greek word "plastikos", meaning plastic) are usually made from high molecular weight organic polymers obtained by polymerization of monomers derived from petroleum, natural gas or coal. This kind of organic polymer plastic connected by C-C covalent bond has excellent performance and has a very wide range of applications in various fields. The development of the world today and people's daily life are inseparable from plastics. However, because the C-C covalent bond in polymer plastics is very stable, it is difficult to break spontaneously in the natural environment, thus causing worldwide white pollution in the natural environment. [0003] At present, there are two main directions to solve the problem of plastic pollution. On the one han...
