Abstract

The invention provides flame retardant glue and a preparation method thereof. The preparation method comprises the following steps: adding ammonium hexachloroiridate and zinc acetate into polyvinyl alcohol and fatty amine polyoxyethylene ether; stirring at the temperature of 90 DEG C for an hour, adding 1-mercapyl methyl acetic acid, stirring at the temperature of 130 DEG C for an hour, adding nonyl phenolic resin, and stirring for 2 hours; adding triphenyl phosphate and magnesium hydroxide, stirring at the temperature of 110 DEG C for an hour; adding methyltrialkoxysilane, and stirring for 15 minutes, thereby obtaining the flame retardant glue. The oxygen index is 31, V0 level; by utilizing a 3M 600 adhesive tape, the adhesive force in a drawing coating test is 5B.

Description

technical field [0001] The invention belongs to the technical field of glue, and in particular relates to a flame-retardant glue and a preparation method thereof. Background technique [0002] Brominated flame retardants release toxic substances during combustion or waste disposal, such as producing a large amount of smoke and irritating toxic gases, and may also produce polybrominated dibenzofuran (PBDF), dioxin (dioxin) and other high Toxic substances that are carcinogenic and cause deformities in animals, and it is also very difficult to treat or recycle bromine-containing wastes, so it is necessary to find environmentally friendly flame retardants that replace halogens. [0003] Most of the currently commercially available glue sticks use PVA and PVP as adhesives, which have low production costs and the performance of solid glue sticks, and have good market competitiveness in adhesion, moisture retention, shaping, and coating. However, according to the QB / T2857-2007 tes...
