Preparation method of environment-friendly bottle cap capable of being repeatedly used

Abstract

The invention relates to the field of novel materials, in particular to a preparation method of an environment-friendly bottle cap capable of being repeatedly used, which comprises the following steps: step 1, preparing a mold: preparing a corresponding mold according to the shape of the bottle cap; 2, feeding: adding raw materials into a high-speed stirrer, uniformly mixing, and putting the mixture into an injection molding machine for melting and plasticizing to obtain a plasticized material; 3, molding: adding the plasticized material into the mold through injection molding, adding a nucleating agent, and carrying out injection molding; and 4, demolding to obtain the environment-friendly bottle cap capable of being repeatedly used. The problems that the common degradable plastic polyamide at present has the defects of easy water absorption and poor high and low temperature resistance, which limit the application of the degradable plastic polyamide on the bottle cap, are solved. Thebottle cap prepared by the method disclosed by the invention can be repeatedly used for multiple times without being damaged, and the adopted raw materials belong to environment-friendly materials andaccord with a sustainable development strategy.

Description

technical field [0001] The invention relates to the field of new materials, in particular to a preparation method of a reusable environment-friendly bottle cap. Background technique [0002] With the development and progress of society, bottled containers have become common items that can be seen everywhere in people's lives. However, in recent years, although there have been many improvements to the bottle, there are not many improvements to the material of the bottle cap. , Most of them still use traditional PVC materials. However, in today's increasingly strong environmental awareness, traditional bottle caps can no longer meet people's needs. The non-degradability of PVC has made it gradually unpopular. However, ordinary Degradable plastic polyamide has the defects of easy water absorption and poor high and low temperature resistance, and these defects limit its application in bottle caps. SUMMARY OF THE INVENTION [0003] In view of the above problems, the present in...

[0002] With the development and progress of society, bottled containers have become common items that can be seen everywhere in people's lives. However, in recent years, although improvements to bottles have emerged in an endless stream, there are not many improvements to bottle cap materials. Bottle caps are a necessary part of sealing bottles. , most of them still use traditional polyvinyl chloride materials. However, with the increasing awareness of environmental protection, traditional bottle caps can no longer meet people's needs. The non-degradability of polyvinyl chloride makes it gradually unpopular. The degradable plastic polyamide has the defects of easy water absorption and poor high and low temperature resistance, and these defects limit its application in bottle caps
