Abstract

The invention discloses a wear and hydrolysis resistant PBT material, a preparation method and a dish washing machine. The wear and hydrolysis resistant PBT material comprises the following components in parts by weight: 60 to 95 parts of PBT resin, 0 to 35 parts of wear resistant agent, 0.2 to 5 parts of hydrolysis resistant agent, 0.2 to 0.5 part of composite antioxidant, and 0.4 to 1 part of processing auxiliary agent. The provided wear and hydrolysis resistant PBT material has the advantages of excellent hydrolysis resistant property, small surface friction coefficient, small wear coefficient, good weatherability, and stable property. The dish washing machine comprises parts that are prepared from the wear and hydrolysis resistant PBT material, so the dish washing machine has a stable performance and the user experience is improved.

Description

technical field [0001] The invention belongs to the technical field of dishwashers, and in particular relates to a wear-resistant and hydrolysis-resistant PBT material and a preparation method thereof, a bowl basket and a dishwasher containing the wear-resistant and hydrolysis-resistant PBT material of the invention. Background technique [0002] In general, a dishwasher is a device that removes dirt such as food residues from tableware (tableware) or cookware (hereinafter simply referred to as "tableware") using detergent and washing water. A dishwasher generally includes a housing in which a washing tub is provided; a dish basket movably installed inside the washing tub such that the dish basket moves forward / backward; and a spray unit spraying wash water toward the dish basket, from the spray unit Sprayed wash water is provided to wash dishes. [0003] Therefore, generally, a dishwasher goes through the stages of prewash, main wash, rinse and dry. During the pre-wash ph...
