Summary of the invention
The objective of the invention is at above-mentioned present situation, it is abundant to aim to provide a kind of raw material sources, and technical process is simple, product quality indicator is stable, and individual difference is little, not modification, be beneficial to the later stage powder charge and shoot and launch, saving artificial is the firework touch off base material and the preparation method of base-material with starch.
The implementation of the object of the invention is, is the firework touch off base material of base-material with starch, is the raw material of getting following weight ratio
Starch: 1
Paper pulp (being equivalent to oven dry stock): 0.1-1
Releasing agent 0.01-0.2
And amount of starch 0.6-3.5 water doubly, the material of hot press moulding obtained by molding,
Paper pulp is secondary stock, new paper pulp or market pulp board,
Releasing agent is one or more in stearic acid, silicone oil or the stearate.
With starch is the preparation method of the firework touch off base of base-material, the 0.6-3.5 water doubly of starch total amount will be added behind the paper pulp size degradation, add the starch of 5%-60% amount and the stearic acid in the releasing agent again, be heated to the thorough gelatinization of starch after stirring while stirring, cool slightly, add remaining component, fully be mixed into mud shape thing, get the mud shape thing that is fit to the die cavity amount, insert the mould temperature in 150-280 ℃ mould, the matched moulds insulation is to dry, and depanning promptly gets product.
It is base-material that the present invention adopts with starch, is aided with the paper fiber, the intensity height, when having reduced emission towards the possibility at the end; Adopt the mold pressing one-shot forming technique, technical process is simple, and product quality indicator is stable, and individual difference is little, and modification is not saved artificial.
By mold exchange more, the present invention can produce fire works display projectile shell, firework display pipe, the various fireworks consumptive materials such as a class of setting off, and its profile is level and smooth, associative perception is strong.
The specific embodiment
Firework touch off base material of the present invention is a raw material of getting following weight ratio:
Starch: 1
Paper pulp (being equivalent to oven dry stock): 0.1-1
Releasing agent 0.01-0.2
And amount of starch 0.6-3.5 water doubly, the material of hot press moulding obtained by molding,
Paper pulp is secondary stock, new paper pulp or market pulp board, and the long more intensity, particularly resistance to tension to the increase product of paper fiber is favourable more.
Releasing agent is stearic acid, silicone oil or stearate.Talcum powder also can be used as releasing agent and uses, and when releasing agent was talcum powder, talcous consumption should be 0.2-2 a times of amount of starch.Above-mentioned material as releasing agent can use separately, also can several or all mix with various ratios and use.
Can also add cheap inorganic filler such as calcium carbonate, talcum powder, clay, bentonite, to strengthen the density and hardness of product, the consumption of inorganic filler is 0.5-4 a times of amount of starch.
Can also add plant stuffings such as sawdust, plant straw to increase the density and the volume of material, the consumption of plant stuffing is the 10%-80% of amount of starch.
Starch can partly or entirely be substituted by the powder of flour, ground rice, potato class or in the mud one or more.
Starch can also part be substituted by land plaster, polyvinyl alcohol glue or other hydrophilic adhesive material matter.
The preparation method of firework touch off base will add the 0.6-3.5 water doubly of starch total amount behind the paper pulp size degradation, add the starch of 5%-60% amount and the stearic acid in the releasing agent again, be heated to the thorough gelatinization of starch after stirring while stirring, cool slightly, add remaining component, fully be mixed into mud shape thing, get the mud shape thing that is fit to the die cavity amount, insert the mould temperature in 150-280 ℃ mould, the matched moulds insulation is to dry, and depanning promptly gets product.
As used inorganic filler, and cool slightly after the thorough gelatinization of starch, add 0.01-0.2 times releasing agent of amount of starch, the 0.5-4 inorganic filler and the remaining starch doubly of amount of starch.

By mold exchange more, can make fire works display projectile shell, firework display pipe with the present invention, the various fireworks consumptive materials such as a class of setting off.Accompanying drawing is the integral type combined firework transmitting tube with the present invention's preparation.Emission has emission tube chamber 2 in the pedestal 1 among the figure, and there is the fuse hole 3 that communicates with fornix 4 at the bottom of the pipe at the bottom of the emission pedestal at 2 ends of emission tube chamber, manage between the end fornix 4 and walk approaching channel 5
The integral type combined firework transmitting tube pipe of preparation, seat one, its benefit are that for each emission tube chamber, the tube chamber that its periphery is adjacent forms " arch " shape to it and supports.The huge expansive force that the antagonism powder burning produces has been converted to the resistance to compression of peripheral tubes by the tension of this pipe.So this structure has strengthened the anti-dilatancy of every transmitting tube greatly, reduced the risk of quick-fried tube.In addition, also have the characteristics that profile is level and smooth, associative perception is strong.
The pipe end, connect letter; Under the effect of gravity, the lift-off gunpowder can concentrate on the transmitting tube bottom, connects letter with the pipe side and compares, and it is easier, more reliable to light a fire.The vault body structure of pipe end reverse side; Strengthened the pipe compression strength at the end greatly, when having reduced emission towards the possibility at the end.Base is communicated with the approaching channel of walking of each pipe; Allow the fuse that connects each pipe from groove, pass through, do not allow it expose, avoided fuse to be broken.
