Flexible, insulating and heat-conducting ribbon

Abstract

The invention discloses a flexible, insulating and heat-conducting ribbon. The flexible, insulating and heat-conducting ribbon is produced from, by weight, 70-95 parts of polyphenylene sulfide, 80-95parts of soluble polytetrafluoroethylene, 10-20 parts of polyformaldehyde, 2-5 parts of carbon nanotubes, 20-30 parts of red mud, 5-10 parts of carbon fibers, 2.5-11.5 parts of staple silicon carbidefibers, 13.5-21.5 parts of barium titanate whiskers, 11-27 parts of boron nitride nano-sheets, 1-2 parts of a coupling agent and 1-2 parts of an antioxidant. The flexible, insulating and heat-conducting ribbon disclosed in the invention has the advantages of good insulating and heat-conducting property, high cost performance, low price, good flexibility, comfortableness, stable chemical propertiesand long service life.

Description

technical field [0001] The invention belongs to the technical field of webbing production, and in particular relates to a flexible insulating and heat-conducting webbing. Background technique [0002] At present, the manufacturing methods for making fiber fabrics with thermal conductivity are mainly based on fiber surface carburizing method, metal or non-metal conductive particle coating method, metal and non-metal fiber blending method, chemical, electrochemical method, sputtering film forming method, etc. Thermally conductive fiber fabric. The conductive fiber fabric made by the above method is applied to highly flexible products, that is, it presents different technical defects. Described on everyday products that are used by customers. (1) electric heating clothes; (2) electric heating seat cushions, the main defects in practical applications are as follows: (1); conductive particles are easy to fall off from the surface of the fabric; (poor adhesion) (2); poor rubbing...

AI Technical Summary

Problems solved by technology

(1) electric heating clothes; (2) electric heating seat cushions, the main defects in practical applications are as follows: (1); conductive particles are easy to fall off from the surface of the fabric; (poor adhesion) (2); poor rubbing resistance: (with With different kneading and folding, the resistivity will increase permanently, and eventually lose the thermal conductivity) (3); poor acid and alkali resistance: (the thermal conductivity will be destroyed in case of strong acid and alkali) (4); long-term exposure to the atmosphere is easy to oxidize; (durable Poor resistance, resistivity decreases with time) (5); poor washing resistance

The above defects limit the product application of the above technology types

[0003] At present, the most widely used electric heating materials are alloy electric heating wires and carbon fibers coated with PVC and PE. The product has poor hand feeling and comfort, and the thermal feeling is also poor. Because the electric heating materials are linear, the heat is concentrated on one line, so the temperature feels dry and hot. , so as to withstand high temperature and low safety factor
