Title:
ANTI-ULTRAVIOLET PBT COMPOSITE, PREPARATION METHOD THEREFOR, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/052410
Kind Code:
A1
Abstract:
Disclosed are an anti-ultraviolet PBT compound, a preparation method therefor, and the use thereof. The PBT composite comprises the following components: PBT, fiberglass, lignin, a toughening agent, and an antioxidant, wherein the average diameter of the fiberglass is less than or equal to 13 μm, and the pH of the lignin is 7.0 to 8.0. In the present invention, safe, efficient and environmentally friendly lignin is used as an ultraviolet absorber for PBT, instead of a chemical anti-ultraviolet agent which is commonly used in the market currently, and the prepared PBT composite containing the lignin has a good anti-ultraviolet performance. In addition, by means of the mutual cooperation of the low-diameter fiberglass, the toughening agent, etc., with the PBT and the lignin, the problem of a decreased mechanical performance of PBT caused by the addition of lignin is alleviated. Therefore, a PBT composite with both a mechanical performance and an anti-ultraviolet performance is prepared and obtained, the initial tensile strength of the PBT composite is greater than or equal to 100 MPa, and after ultraviolet aging, the tensile strength retention rate of the material is greater than or equal to 90%.
