Abstract
The invention relates to a gasoline scrubbing-resistant PBT (polybutylene terephthalate) material. The gasoline scrubbing-resistant PBT material is prepared from the following components in parts by mass: 64 to 82.9 parts of PBT resin, 15 to 25 parts of epoxy resin, 1.0 to 5.0 parts of polyvinyl alcohol, 0.5 to 3.0 parts of toughener, 0.2 to 1.0 part of antioxidant, 0.2 to 0.5 part of PETS, and 0.2 to 1.5 parts of coupling agent, wherein the PBT resin is milky white, and the characteristic viscosity is 0.7 to 0.8dl / g; the toughener is a POE-g-GMA and POE-g-MAH compound; an adhesive additive is a powdery epoxy resin and polyvinyl alcohol compound; the coupling agent is aminopropyltriethoxysilane. A preparation method of the low temperature impact-resistant PBT material with spraying-free and pearl effect comprises the following steps of stirring the PBT resin, the powdery epoxy resin, the polyvinyl alcohol, the silane coupling agent, the toughener, the antioxidant, the PETS and the dried pearl powder for 3min at the stirring speed of 2000r / min; adding the mixed raw materials into a material hopper, and enabling a double-screw extruder to extrude and granulate, wherein the extrusion temperature is 235 to 250 DEG C, and the rotation speed of each screw is 400 to 450r / min, so as to obtain the gasoline scrubbing-resistant PBT material.
Description
technical field [0001] The invention relates to the technical field of modification of polybutylene terephthalate (PBT) plastics, in particular to a polybutylene terephthalate (PBT) plastic that can be resistant to gasoline scrubbing. Background technique [0002] Polybutylene terephthalate (PBT) is an engineering plastic with good dimensional stability, fast crystallization, excellent electrical properties and chemical resistance. Because of the above characteristics, it is widely used in electrical and electronic, auto parts and office supplies parts. [0003] Products prepared from existing PBT materials (such as office supplies and auto parts) need to indicate the model of the product and some technical parameters after production is completed, and inkjet printing will be used on the surface of the product. However, the content printed in some application places (automobile repair) by ink printing is not resistant to gasoline scrubbing, so the technical parameters of th...
