preparation example Construction

[0029] Correspondingly, the present invention also provides a method for preparing the above-mentioned antibacterial non-stick pan handle, which includes the following steps: pour 20-25 parts by weight of polytetrafluoroethylene into the first mold, heat to 330-380°C, and make the non-stick handle The body of the pot handle is inserted into the first mold, and after heat preservation, it is lowered to 280-320°C, and after heat preservation for 20-60 minutes, the temperature is lowered to form, and the crude non-stick pot handle is obtained; 20-25 parts by weight of polyphenylene sulfide, 20-25 parts by weight Pour parts by weight of polytetrafluoroethylene, 0.5-1 parts by weight of silicone cross-linking agent and 1-5 parts by weight of nano-silver into the second mold, heat up to 330-380 ° C, stir and melt, and then put the non-stick pan handle The crude product is inserted into the second mold, cooled to 280-320° C. for heat preservation, and the antibacterial non-stick pan h...

Abstract

The invention provides an antibacterial non-stick pan handle and a preparation method thereof. The handle is prepared from the following raw materials: polyphenylene sulfide, polytetrafluoroethylene, nano silver, a silane crosslinking agent, and a substrate material. Polyphenylene sulfide has the advantages of excellent high-temperature resistant, corrosion-resistant, radiation-resistant, and flameproof performances, balance physical mechanical property, high size stability, and excellent electrical property; can be blended with polytetrafluoroethylene to obtain a polyphenylene sulfide / polytetrafluoroethylene alloy; greatly improves the mechanical property, lubricating performance and corrosion resistant performance of polytetrafluoroethylene, and reduces the cost. Moreover, the compatibility between polyphenylene and inorganic fillers is good, so nano silver with an antibacterial function can be evenly dispersed in the non-stick pan handle to fully exert the antibacterial function. The structure of the silane crosslinking agent is stable, the heatproof property and stability of silane crosslinking agent are high, only a little amount of silane crosslinking agent can achieve ultrahigh crosslinking degree, and thus the non-stick pan handle becomes more durable. The experiment results show that the prepared antibacterial non-stick pan handle has an excellent antibacterial performance.

Description

technical field [0001] The invention relates to the technical field of functional plastics, in particular to an antibacterial non-stick pan handle and a preparation method thereof. Background technique [0002] People's daily life is inseparable from clothing, food, housing and transportation, and people's pursuit of delicious and safe food is far from endless. Today, when science and technology are highly developed, the cooking utensils used by people also rely heavily on the use of pots. The invention of PTFE-coated non-stick pans has greatly facilitated people, but its potential carcinogenicity has gradually attracted the attention of the society. Many workers put a lot of energy into finding new types of thermally conductive non-stick coatings, and have also developed enamel non-stick pans, polyetheretherketone non-stick coatings, and other mixed resins to replace polytetrafluoroethylene to produce non-stick pans. [0003] On the other hand, people are not only satisfi...
