Abstract
The present invention is a kind of manufacture method of fire safety firecracker.Its characteristics are that the firecracker paper web is that a kind of paper of handling through fire retardant of employing is that raw material is made.The fire retardant of its use is formulated by chemical substances such as urea, phosphoric acid, ammoniacal liquor, formaldehyde.The serviceability of this fire prevention firecracker and effect and general firecracker are as good as, and the paper scrap after setting off does not have remaining Mars.Therefore, this fire prevention firecracker has the characteristics of fire safety, has thoroughly eliminated the remaining kindling material of setting off the back paper scrap because of firecracker and has caused the hidden danger of fire.
Description
The present invention relates to a kind of manufacture method of fire safety firecracker.
General firecracker is made up of lead-in wire, gunpowder and paper web, but the paper web that the firecracker of past production is used all is to adopt common paper to produce, often the remaining Mars that has because of paper scrap after this firecracker is seted off is stretched and is caused fire, causes very big loss for the country and people's lives and properties.
The manufacture method that the purpose of this invention is to provide a kind of fire safety firecracker is eliminated because of setting off firecracker and is caused the possibility of fire.
The raw material paper that measure of the present invention is the firecracker paper web is handled through fire retardant, has fireproof characteristics safe in utilization with the firecracker of this paper web manufacturing.
The present invention handle the firecracker paper web with the fire retardant of paper be earlier with 10 times of water to urea urea, dissolving adds phosphoric acid, ammoniacal liquor is slowly added and stirring (or the reversed order that adds phosphoric acid and ammoniacal liquor) again, make the pH value of liquid this moment equal or be slightly larger than 7, add formaldehyde at last.Wherein the weight proportion of each chemical substance is a urea: phosphoric acid (percent concentration gets 85%): ammoniacal liquor (percent concentration gets 25%～28%): formaldehyde (percent concentration gets 36%～38%) is 1: 4: 7: 2.The fire retardant that is mixed with in this way is a kind of colourless, tasteless, non-corrosive liquid.
The paper of handling with above-mentioned fire retardant, except that the paper look little be the soft property of yellow and paper poor slightly, other physical property is as good as with general paper.And this paper is placed flame, this paper is carbonization and not burning.With the firecracker paper web that this treated paper is made, set off the back paper scrap at firecracker and do not have remaining Mars, and do not change the original handling characteristics and the effect of firecracker.Therefore this firecracker has good fire safety performance and serviceability.In addition, also can be used for handling other with this fire retardant the paper that uses in the occasion of fire protection requirement is arranged.
Example: the water with 10 grams dissolves 1 urea that restrains, add concentration then and be 85% phosphatase 24 .2 gram, be 7 gram concentration that 25%～28% ammoniacal liquor is slowly poured (or add ammoniacal liquor earlier and then add phosphoric acid) into again, make the liquid of this moment be neutrality or alkalescence, there are this moment gas and white granular material to generate in the liquid, along with stirring the white granular substance dissolves, adding concentration at last is 36%～38% formaldehyde 2 grams.So far, the fire retardant preparation is finished, and should note protection in process for preparation, in case hinder eyes owing to reacting acutely to spatter between chemical substance.The water that must add one times when fire retardant uses again stirs, the fire retardant of this dilution is coated on instruments such as brushes on the raw material of firecracker paper web or with raw material paper and soaks in fire retardant, raw material paper is running through through fire retardant and dry back just can be used as the paper web of manufacturing firecracker.Through experimental results show that the firecracker firework display effect that uses this paper web manufacturing be as good as with general firecracker and set off after paper scrap do not have remaining fire and suffer from, reached the purpose of fire safety.
Claims (2)
1, a kind of manufacturing of the fire prevention firecracker of being made up of lead-in wire, gunpowder and paper web is characterized in that it is the paper web that raw material is made that firecracker has adopted a kind of paper of handling through fire retardant.
2, the manufacturing of fire prevention firecracker according to claim 1, it is characterized in that handling the fire retardant of the raw materials used paper of firecracker paper web for 10 times of water urea being dissolved earlier to urea, add phosphoric acid then, ammoniacal liquor slowly being added again and stir pH value that (perhaps the reversed order that adds phosphoric acid and ammoniacal liquor) make liquid this moment equals or is slightly larger than 7, add formaldehyde at last, wherein the weight proportion of each chemical substance is a urea: phosphoric acid (percent concentration gets 85%): ammoniacal liquor (percent concentration gets 25%～28%): formaldehyde (percent concentration gets 36%～38%) is 1: 4: 7: 2.
