Problems solved by technology

However, the elasticity of nylon fiber is too strong, and its elastic recovery rate is comparable to that of wool, so it is difficult to form and it is difficult to be used as a sealing weaving substrate

Abstract

The invention discloses a sealing braided base material for foodstuff processing machinery. The base material comprises a core layer and a skin layer; the core layer employs continuous nylon fiber bundles; the skin layer employs nylon fiber yarn having a S-twist structure with the twist being 80-100; the skin layer is clockwise wound around the outer surface of the core layer; and the core layer is provided with a silane coupling agent and an antistatic agent. The invention also discloses a method for preparing the sealing braided base material for foodstuff processing machinery. The method comprises following steps: preparing a compound molding agent by the use of the silane coupling agent and the antistatic agent with the ratio being 1:1; soaking the continuous nylon fiber bundles in the compound molding agent for 3-5 minutes; preparing the nylon fiber yarn by the use of nylon fibers based on the S-twist structure with the twist being 80-100; and clockwise winding the nylon fiber yarn around the outer surface of the continuous nylon fiber bundles after the continuous nylon fiber bundles are soaked in the compound molding agent. According to the invention, a problem that nylon fibers are difficult to mold as the nylon fibers are high in elasticity is solved, and the sealing braided base material is ageing resistant, and is high in sealing performance and antibacterial performance.

Description

technical field [0001] The invention relates to a sealing braided base material used for manufacturing seals of food processing machines, in particular to a sealing braided base material used for food processing machines and a preparation method thereof. Background technique [0002] The sealing element is installed in the sealing box, and the sealing element is pressed on the surface of the shaft through the sealing gland. Because the surface of the shaft is always somewhat rough, it can only be partially attached to the seal, but partially not in contact, thus forming countless labyrinths. When the pressurized medium passes through the surface of the shaft, the medium is throttled several times, and the seal is achieved by virtue of this "labyrinth effect". The fit and friction between the seal and the shaft surface are also similar to sliding bearings. There should be enough liquid for lubrication to ensure that the seal has a certain life, which is the so-called "bearin...
