Title:
COMPOSITE BARIUM SULFATE FILLING MASTERBATCH FOR FILLING OF TRANSPARENT PLASTIC AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/272565
Kind Code:
A1
Abstract:
Disclosed is a composite barium sulfate filling masterbatch for the filling of a transparent plastic, which is composed of the following components in percentage by weight: 1.4-2.0% of stearic acid, 1.2-1.8% of a coupling agent, 8-20% of low-density polyethylene, 1.8-2.8% of polyethylene wax, and 0.1-0.3% of a template modifying agent, with the balance being barium sulfate. Due to the addition of the template modifying agent composed of glass fiber cotton and a graphene film, the strength of the material can be significantly improved, and the arrangement order of raw materials in the masterbatch can be effectively improved, thereby improving the transparency after same is applied to the filling of the transparent plastic. The specific principle is speculated as follows: the template modifying agent has a double-layer structure composed of the glass fiber cotton and the graphene film, and there are a large number of uniformly-arranged micropores on the surface of one side of the graphene film, which are beneficial for the uniform and fine arrangement of barium sulfate powders, such that the masterbatch can be applied to transparent plastic to achieve better transparency.
