Abstract

The invention relates to a TPV material and a preparation method and application thereof. The TPV material is mainly prepared from, by weight, 8-30 parts of PP, 15-50 parts of EPDM, 15-50 parts of paraffin oil, 1-10 parts of polyolefin, 0-12 parts of inorganic filler, 0.5-6 parts of vulcanizing agent composition, 0.5-4 parts of assistant vulcanizing agent composition, 0.1-4 parts of zinc oxide, 0.5-2 parts of antioxidant composition, 0.5-4 parts of ultraviolet light absorber composition, 0.5-8 parts of lubricant composition and 2-5 parts of color masterbatch. The TPV material is prepared through material mixing and vulcanizing. The prepared TPV material has higher surface fine and smooth degree, tensile strength and tear strength, better compression permanent deformation and more stable heat aging and the aging. The TPV material is used for the preparation of automobile glass water-draining strips, can meet the appearance demand for high surface fine and smooth degree of an auto main engine plants, as well as the compression permanent deformation and physical property requirements for light and heat aging.

Description

technical field [0001] The invention relates to a polymer material, in particular to a TPV material and its preparation method and application, belonging to the technical field of polymer materials. Background technique [0002] TPV (thermoplastic vulcanizate) mainly has two parts, one is plastic as the continuous phase, and the other is rubber as the dispersed phase. At present, the processing method of producing TPV is relatively traditional, which is to melt and blend PP, EPDM, paraffin oil and some small materials to obtain a semi-finished product, then add a vulcanizing agent to obtain another vulcanized semi-finished product, and then add a weathering additive to melt blend to obtain The final product has cumbersome process steps, low production capacity and high energy consumption. Moreover, the vulcanized rubber particle size of the produced product is too large, the particle size distribution is too wide, and the key data such as tensile strength, tear strength, an...
