Problems solved by technology

The varnish-yarn process was used for the bonding between the squib and the spherical shell, the construction speed is slow and the sealing is difficult to guarantee
The invention patent with the application number of 200410045044 discloses a solvent-based adhesive with ABS, polymethyl methacrylate, and vinyl acetate resin as the main resin, which is used for bonding the paper spherical shell of the fireworks shell to the paper fuse. High bonding strength, fast curing speed, and good effect. With the continuous advancement of fireworks industry technology, the characteristics of the fuse tube product have changed. First, the surface of the paper fuse tube has changed from rough to very tight. , very smooth, and the second is that some fireworks shell manufacturers no longer use paper squibs but use PE and PP plastic squibs. Can not meet the technical requirements, must seek new positioning glue

Embodiment 1

[0028] Weigh 120 # Solvent gasoline, butanone, ethyl acetate, mixed evenly. Take out 20% from the mixed solvent, put it into a high-speed disperser, start stirring at a speed of 120 rpm, add terpene resin, modified glycerin rosin resin, stir and dissolve for 1 hour, and increase the speed of the disperser to 4000 rpm Slowly add nano-silica and nano-calcium carbonate, continue stirring for 45 minutes after adding, reduce the speed to 200 rpm, and set aside to obtain a nano-material dispersion.

[0029] Add the remaining mixed solvent into the stirred reactor, start stirring, add SBS resin, dissolve at room temperature for 3.5 hours, add C9 petroleum resin, antioxidant-264, dissolve for 1 hour, then add kaolin, stir and disperse for 40 minutes, and finally Add the nanomaterial dispersion liquid in the high-speed disperser, stir for 50 minutes, and filter the material.

Abstract

The invention relates to a nano-modified salute bomb location glue and method for preparing same. The glue uses SBS elastomer as the major material, addes with adhesion resin and nano-materials to reinforce the surface adhesive force and adhesion strength between the location glue and ignition pipe and the ball shells.

Description

technical field [0001] The invention relates to a nano-modified SBS adhesive, in particular to a nano-modified SBS adhesive used for positioning fireworks shells. Background technique [0002] The fireworks bomb in the fireworks series is a festive product that is launched into the air by propellant and explodes in the air to form a colorful picture. The main spherical shell of the fireworks shell is composed of two hemispherical paper shells, and the outer surface is cemented and reinforced with kraft paper. It contains explosives, effect drugs and accessories. There are 1 to 2 fuse tubes on the spherical shell, and fuses are installed in the tubes. It is required that the fuse tubes and the spherical shell be firmly bonded and tightly sealed. The varnish-yarn process was originally used for the bonding between the squib and the spherical shell, and the construction speed was slow and the sealing was difficult to guarantee. The invention patent with the application number...
