Embodiment Construction

[0017] In order to better understand the present invention and its technical effects, the present invention will be described below through specific examples.

[0018] Ammonium dihydrogen phosphate is a white crystal that is usually used as a fertilizer, and is also used in dry powder fire extinguishers. It uses the endothermic decomposition of ammonia and phosphoric acid in the combustion flame. The reaction is an endothermic reaction and has a better cooling effect; the decomposition produced Free ammonia can react with OH free radicals generated in the flame combustion reaction, reduce and terminate the free radicals generated by the combustion reaction, and reduce the combustion reaction rate; when the concentration of free ammonia in the flame is high enough and the contact area with the flame is large enough, the free radicals stop The rate is greater than the rate of combustion reaction formation, and the chain combustion reaction is terminated, resulting in flame exting...

Abstract

The invention provides an ultrathin fireproofing and flame-retardant double faced adhesive tape. The double faced adhesive tape comprises a base film layer, wherein flame-retardant layers are arrangedon two surfaces of the base film layer respectively, and adhesive layers are arranged on the surfaces, opposite to the base film layer, of the two flame-retardant layers. The double faced adhesive tape is characterized in that a flame retardant is arranged in the flame-retardant layers and the adhesive layers and contains ammonium dihydrogen phosphate and meso-tetraphenylporphyrin. The ultrathinfireproofing and flame-retardant double faced adhesive tape is applicable to the adhesion of parts of electronic products, particularly batteries and the like of intelligent mobile phones; by utilizing a dual fireproofing and flame-retardant technique, the fireproofing and flame-retardant effects are good; and the double faced adhesive tape is light and thin and has good applicability.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a double-sided adhesive with fireproof and flame retardant functions. Background technique [0002] Adhesives are widely used in the technical field of electronic products, for example, the bonding of lithium batteries inside smartphones and other products and the bonding of spare covers, and the bonding between structural parts of smartphones. Double-sided tape is also often used for bonding between electronic product parts. However, with the popularization of the above-mentioned products, especially smart phones, there are many unsafe factors in use, such as bumping, falling, etc., which may cause the displacement of the battery, which may cause safety hazards such as burning or even explosion of the battery. In the new consumption environment and communication environment, as consumers pay more and more attention to product safety, any adverse effects caused by ...
