Abstract

The invention relates to a stirrer material and a preparation method thereof, in particular to a coffeepot stirrer material and a preparation method thereof. The material comprises, by weight, 75-90 parts of polyamide, 5-20 parts of functional elastomers, 3-15 parts of functionalized polyolefin, 3-10 parts of fillers, 0.5-3 parts of wear-resistant assistants and 0.5-2 parts of other assistants. The coffeepot stirrer material has the advantages of high strength, high rigidity, low linear expansion coefficient, high dimensional stability, no warpage deformation, high wear resistance and the like, and the long-term normal use of a coffeepot stirrer in high-speed stirring, high temperature and low temperature environments is satisfied; the long-standing problems of stirrers, including easinessin adsorption and difficulty in removal of coffee stains, are solved, the food use requirements are met, and no toxic or harmful substance is precipitated or left.

Description

technical field [0001] The invention relates to a coffee pot stirrer material and a preparation method thereof, belonging to the technical field of materials. Background technique [0002] At present, the coffee pot stirrers on the market are mainly made of nylon 6 composite materials. During use, they face the following problems: 1) When rotating at high speed, they are prone to deformation and have poor dimensional stability; 2) Wear resistance under high-speed operation Unqualified; 3) During use, coffee stains are easily adsorbed to the surface of the mixer, which is difficult to remove and poses a health hazard. So far, the above problems have not been resolved. Contents of the invention [0003] The material of the present invention has the characteristics of excellent tensile strength, low coefficient of linear expansion, good dimensional stability, no warping deformation, excellent wear resistance, etc., and satisfies the long-term normal operation of the coffee p...
