Description
Technical field
The present invention relates to the preparation method of a kind of firework touch off base material and pedestal.
Background technology
Generally popular in the market pedestal, as the fireworks combination, its transmitting tube is that some isometric paper tube lower ends are stifled with mudding, puncture is combined into row's back papering to them then and fixes to connect letter on the tube wall of pressing close to mudding above the mudding.With several this same pipe numbers or different " pipe rows " gather into folds from level to level and papering is fixed, form " Guan Zhen " that rectangular arranged or other polygons are arranged, just formed fireworks combined transmit pipe.Its production method is, by pipe crimping, beat mud (back cover), dazzling, connect letter, compose and lay out, bond, folded row, apply step such as paper hoop.Complex technical process not only, cost of manufacture is higher, and the paper tube easy deformation, influences launching effect, and the more important thing is that it wants a large amount of consume paper, is unfavorable for environmental protection.
Chinese patent " a kind of biological degradable disposable lunch-box " (patent No. 97109188.9) proposed once that a kind of what be used to make the disposable and convenient cutlery box is the biodegradable material of base-material with starch.Cutlery box becomes pug by gelatinized starch, string, waterproofing agent, releasing agent after fully kneading, then this pug is made through the hot press moulding moulding with lining paper.This material is mainly used to make all kinds of cutlery boxs and other disposable tablewares, as bowl, dish, dish, cup etc.
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.
Figure of description
Accompanying drawing is the structural representation of the one combined firework transmitting tube produced of the present invention
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 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 10%-80% of an 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, 0.5-4 times the inorganic filler and the remaining starch of amount of starch.
