Problems solved by technology

[0003] The present invention provides a high-performance impregnating agent and impregnating method for braided packing, which mainly solves the problem in the prior art that the impregnating liquid used in the preparation method of the existing packing makes the thermal conductivity of the packing poor, so When used in occasions with granular media and high linear speed, it is easy to produce creep, and at the same time, the product wears a lot, which reduces the dimensional stability, softness and extrusion resistance of the product, resulting in the technology of running, popping, dripping, leaking, etc. question

Abstract

The invention relates to a high performance impregnant for braided packing and impregnation process thereof. The invention mainly solves the technical problems of poor thermal conductivity of existing packings prepared by the prior art, so that creep deformation is formed under the condition of higher linear velocity and granular media existed and performance degradation of products in size stability, pliability and extrusion resistance property is generated due to the large amount of abrasion loss, as well as water leakage. The impregnant provided by the invention comprises, by mass, 15%-25% of distilled water, 65%-75% of graphite emulsion and 10%-20% of polyacrylate adhesive.

Description

technical field [0001] The invention relates to an impregnating agent for braided packing, in particular to a high-performance impregnating agent for braided packing and a process method. Background technique [0002] At present, gaskets, gaskets and packings made of a single fluoroplastic (such as polytetrafluoroethylene, polyfluoroethylene propylene), asbestos rubber sheet or silicone rubber are mostly used as sealing materials. Gaskets, gaskets and packings made of asbestos rubber sheets and silicone rubber materials are randomly distributed, have strength only in certain directions, have poor creep resistance, are prone to aging, and have a short service life. A Chinese patent discloses a nano packing and its manufacturing method (authorized announcement number: CN 100341972C), which includes packing matrix materials and additives, the additives include special nano anti-wear and corrosion inhibitors, special nano anti-wear and corrosion inhibitors Accounting for 8%-46%...
