Preparation method of insulation thermal-conductive canvas

Abstract

The invention discloses a preparation method of insulation thermal-conductive canvas. The method is characterized by comprising the following preparation steps: step 1, performing twill weaving on polyester fibers by using a braiding machine, wherein the polyester fibers adopt 50-100 D of filaments; step 2, mixing a polyamide hot melt adhesive and phenolic resin according to a mass ratio of the polyamide hot melt adhesive to the phenolic resin of (3-5):1, placing the obtained mixture in a beaker, performing melting under heating and stirring, and performing uniform mixing to obtain an adhesivefor standby application; step 3, preparing a polyimide film insulation layer material; and step 4, performing bonding. The method provided by the invention modifies the technical problem that a current conductor protective layer has a low service life, is greatly affected by the environment, easily accumulates internal energy and cannot release the internal energy in time; and the insulation conductor canvas prepared by adopting the method is an excellent heat conductor, polyester canvas is compounded with a polyimide film, so that the insulation conductor canvas has higher insulation performance, and at the same time, the polyester canvas has better strength during use to prevent a conductor from being stretched and deformed under external force.

Description

technical field [0001] The invention relates to the field of canvas, in particular to a preparation method of an insulating and heat-conducting canvas. Background technique [0002] Canvas is a thicker cotton or linen fabric, named after it was originally used for sails. Generally, plain weave is used, a small amount of twill weave is used, and multi-strand yarns are used for warp and weft yarns. Canvas is usually divided into two categories: coarse canvas and fine canvas. Coarse canvas, also known as tarpaulin, has good waterproof performance, and its biggest feature is that it is durable. It is used for covering automobile transportation and open warehouses, and setting up tents in the wild. Fine canvas is used to make labor protection clothing and its supplies. After dyeing or printing, it can also be used as shoe materials, luggage fabrics, handbags, backpacks, tablecloths, tablecloths, etc. Although canvas is widely used, most of its current services are in the low-e...
