Abstract

The invention discloses a preparation method and application of a high-temperature-resistant and low-temperature-resistant nonwoven fabric based adhesive tape. According to the method, through subjecting a nonwoven-fabric-material base material to the treatment with an insulator and corona treatment and then coating an adhesive, using a glass fiber, natural rubber, butyronitrile and isooctyl polyacrylate as main components, on the treated base material, a finished-product pressure-sensitive adhesive is made through processes of drying solidification, compounding isolation, coiling, cutting, packaging and the like. The prepared high-temperature-resistant and low-temperature-resistant nonwoven fabric based adhesive tape is stable in weathering-resistant performance and good in both sealability and water resistance and can be resistant to a high temperature and a low temperature. Meanwhile, the invention also discloses application of the high-temperature-resistant and low-temperature-resistant nonwoven fabric based adhesive tape, made by the preparation method, to the manufacturing of a light industrial material.

Description

technical field [0001] The invention relates to the field of materials, in particular to a preparation method and application of a high temperature and low temperature resistant non-woven fabric base adhesive tape. Background technique [0002] Pressure-sensitive adhesive (PSA) is the abbreviation of pressure-sensitive adhesive, which is a type of adhesive that is sensitive to pressure. The bonding construction of all adhesives is required to be completed under certain pressure conditions, but not all adhesives can be classified as pressure-sensitive adhesives. Pressure-sensitive adhesives refer specifically to adhesives that are sensitive to pressure during the bonding process, do not require heating, do not require solvents, and can be bonded with just a slight press. Its characteristics are that it is not easy to stick, it is not difficult to remove, and it is not damaged when peeled off. The adhesive layer will not dry and solidify in a long period of time, so the press...
