Problems solved by technology

[0004] However, the current PI tapes have problems with flame retardant effects during use, and the commercially available flame retardant acrylate pressure-sensitive adhesives generally have the following problems: (1) Halogenated flame retardants are used in pressure-sensitive adhesives, Although the flame retardant effect is very good, it will produce toxic and corrosive gases; (2) adding inorganic flame retardants, although there is less smoke and no toxic gases when burning, but a large amount of addition often affects the appearance of the product and is no longer transparent (3) The addition of flame retardant will cause the viscosity and initial adhesion of the pressure-sensitive adhesive to decrease significantly. If the viscosity and initial adhesion are less than 1.0kg, it will not be able to stick to the silver aluminum-plastic film. Reduce the probability of flammability and explosion of battery products

Abstract

The invention discloses a flame-retardant glue solution, a preparation method and a full-flame-retardant PI adhesive tape thereof, the flame-retardant glue solution is prepared from the following raw materials in parts by weight: 100-120 parts of an acrylic pressure-sensitive adhesive, 10-15 parts of a flame retardant, 0.5-1.5 parts of a curing agent, 0.1-0.5 part of a coupling agent and 50-70 parts of a solvent, and the flame-retardant glue solution is obtained through dispersion, ultrasonic treatment, grafting and other treatment; the full-flame-retardant PI adhesive tape comprises a release paper layer, a base material layer and a flame-retardant adhesive layer arranged between the release paper layer and the base material layer, according to the full-flame-retardant PI adhesive tape prepared by the invention, the adhesive surface cannot be burnt when the adhesive surface is burnt for 70s by adopting a vertical combustion tester.

Description

technical field [0001] The invention relates to the technical field of flame retardant glue, in particular to a flame retardant glue, a preparation method and a fully flame retardant PI adhesive tape. Background technique [0002] Flame retardant tape is made of acetate fiber cloth and coated with acrylic flame retardant adhesive. There are two colors of black and white available for selection. It has the characteristics of high temperature resistance, good insulation, flame retardant, and high viscosity. [0003] Various adhesive materials are often used in the installation and maintenance of wires and cables and electronic power components. Adhesive tape, as one of them, can be used for the connection of wires and cables, the insulation positioning and packaging of electronic components, etc. With the popularization of mobile phones, mobile phone safety has become an inevitable topic. The mobile phone will heat up during the charging process. If it cannot be removed in t...
