Preparation of novel flame retardant and application of novel flame retardant in flame-retardant adhesive

Abstract

The invention relates to preparation of a novel flame retardant and application of the novel flame retardant in a flame-retardant adhesive. The flame retardant is prepared from an amino-containing organic compound through a one-step reaction, the synthesis conditions are simple and controllable, and the synthesis efficiency is high; and after the flame retardant and the adhesive are blended, the high-flame-retardant adhesive can be obtained. The high-flame-retardant adhesive synthesized by the invention can be directly used as an adhesive of a high polymer material, and has high bonding strength; the adhesive can also be used as a basic formula, and can be used as a composite adhesive after other fillers are added; and the high-flame-retardant adhesive can also be used as a bottom coating agent to realize surface modification of a high polymer material so as to meet different requirements of various special occasions.

Description

technical field [0001] The invention relates to the preparation of a novel flame retardant and its application in flame-retardant adhesives, belonging to the field of polymer material preparation and application. Background technique [0002] Fire has caused great harm to people's lives and property. Flame-retardant materials can prevent fires from happening or buy precious time for people to escape when fires happen, so they are widely concerned. At present, the research on polymer flame-retardant materials is mainly about structural materials, such as flame-retardant sheets, flame-retardant cables, flame-retardant pipes, etc., and there are few literature reports on flame-retardant adhesives. When a fire occurs, it is far from enough for the structural material to be flame retardant. If the adhesive at the seam of the structural material cannot be flame retardant, the fire will burn along the seam or pass through the seam spread inward. Therefore, adhesives with flame-r...

Problems solved by technology

[0007] Although the above strategies can all play an effective flame retardant effect on the substrate, there are still the following problems: the release of toxic and harmful gas-hydrogen halide during the combustion of halogenated flame retardants, which has caused huge harm to human health and the natural environment. Threat; Inorganic flame retardants usually need to be added in large quantities if they want to meet higher flame retardant requirements, but this will greatly affect the mechanical properties of the adhesive and increase the difficulty of processing; organic-inorganic hybrid flame retardant is currently the field of flame retardant It is a very promising development direction, but there are few studies on its application in the field of adhesives, which cannot provide effective reference

Due to its non-polarity, EPDM rubber has low cohesive energy, poor self-adhesion and mutual adhesion, and the highest bonding strength reported so far is only 2.13N / mm

The highest bonding strength reported so far is only 1.5Kgf / cm
