Problems solved by technology

[0003] At present, the wiring PVC plastic materials of earphone products basically use DOP, DINP, and DEHP containing o-benzenes as the plasticizers used in the preparation process. Although the anti-aging and strength of the products meet the requirements for use, the products Ortho-benzene plasticizers are easy to migrate and ooze, and long-term contact with human skin, even if the toxicity is low, long-term exposure and ingestion will cause endocrine disruption, causing reproductive and developmental disorders
In addition, long-term contact of PVC products with ABS / PS plastic shell plastics will cause migration and leakage of plasticizers in PVC products, resulting in migration and discoloration, which will affect the appearance of the products

Abstract

The invention relates to an environment-friendly plastic material, in particular to a non-migration type PVC (polyninyl chloride) environment-friendly plastic material and a preparation method thereof. The non-migration type PVC environment-friendly plastic material is made by mixing and stirring of components comprising, by weight, 100 parts of PVC resin, 10-70 parts of light calcium carbonate, 5-7 parts of non-toxic calcium zinc stabilizers, 0.4-0.8 part of PE-wax, 20-100 parts of saturated polyester resin and 2-4 parts of epoxidized soybean oil. The non-migration type PVC environment-friendly plastic material has the advantages of contact harmlessness with human bodies, plasticizers cannot be migrated and leaked, the environment-friendly plastic material is a high polymer material with heat resistance of 105 DEG C, and is color-stay and non-discolouring.

Description

technical field [0001] The invention relates to an environment-friendly plastic material, in particular to a non-migrating PVC environment-friendly plastic material and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) is one of the five most commonly used synthetic resins in the world. It is widely used in production and life. Flexible packaging materials such as earphones and data cables that are common in daily life are all processed from PVC. However, there are defects in the structure of industrially produced PVC resins, including straight chains and branched chains, and a wide molecular weight distribution. In this way, the polyvinyl chloride resin will degrade and age under the action of external light, oxygen and heat, which will affect the performance of the product. Therefore, a certain amount of heat stabilizers, plasticizers and other additives are often added during the processing of PVC. [0003] At present, the wiring PVC p...
