Problems solved by technology

[0003] Due to the introduction of a large amount of plasticizers and other additives in soft PVC, it is easy to cause migration and precipitation during the secondary processing of the product. The introduction of some additives will reduce the paint adhesion on the surface of the product, thus affecting the printing characteristics of toy products

Abstract

The invention discloses a PVC composition which comprises the following components in parts by weight: 100 parts of PVC resin; 40-120 parts of a plasticizer; and 5-50 parts of a surface modifier. ThePVC composition has outstanding printing performance in the aspect of printing, especially in a softer system of 80A or less, the printing problem of low-hardness soft PVC concerned in the industry iseffectively solved, and the effect of no-clean direct printing without paint peeling is achieved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PVC composition and its preparation method and application. Background technique [0002] Soft PVC has become an important raw material in the toy industry due to its advantages of convenient and diverse molding and processing, easy color matching, soft touch, low cost, strong plasticity, and can meet the personalized design and production requirements of toys. The production of toy products is a labor-intensive industry. In addition to conventional plastic coloring, colorful toys often use methods such as oil spraying and pad printing to meet individual design requirements, and at present, pre-treatment methods are often used to ensure paint attachment Focus on. [0003] Due to the introduction of a large amount of plasticizers and other additives in soft PVC, it is easy to cause migration and precipitation during the secondary processing of the product. The introdu...
