Abstract
The invention discloses a quick set lead fixing agent. The quick set lead fixing agent is obtained by the following steps of: firing blocky weathered stones at high temperature, ball-milling to obtain weathered stone powder with the fineness of more than 200 meshes, and mixing the weathered stone powder and silica sand in a weight ratio of (20-30):(70-80). The lead fixing agent is prepared by mixing mineral substances with rich content, has a good curing effect and is short in curing time, and the curing time at the temperature of between 7 and 9 DEG C is 2 to 3 hours and is shortened by over 3 times compared with the curing time of the conventional magnesium chloride curing agent, so that the mass production is facilitated, the production work efficiency is improved, local resources are also fully utilized, the manufacturing cost of the lead fixing agent is reduced, and the manufacturing cost of the lead fixing agent is reduced by one third compared with the cost of the magnesium chloride curing agent; and meanwhile, the lead fixing agent cannot absorb moisture easily, is not required to be sealed and stored before being used, and is convenient to store and transport.
Description
Technical field
The present invention relates to solid flashing composition, especially relate to the fast set lead fixing agent that is used for anchor leg and sealing that fireworks and firecracker uses.
Background technology
Fireworks and firecracker is one of celebrating article of commonly using of people.The fireworks manufacturing generally will be drawn through system cylinder, dress soil, powder charge, cultivation, curing is sealed, tie the operations such as whip and packing, wherein solidifying sealing process refers to be fixed and fireworks and firecracker is sealed with the lead-in wire that solid flashing composition will be planted, this procedure is no matter be to adopt craft or machinery to finish, and just can enter next procedure after the solid flashing composition such as only having to solidify fully.Therefore set time length, fireworks production preparation and production efficiency are had great effect, set time is long, production preparation amount is large, the production cycle is long, production efficiency is low, otherwise, with short production cycle, the production efficiency height.At present in the fireworks and firecracker industry, the kind of solid flashing composition mainly contains: the one, mix the solid flashing composition that caking is made through pulverizing again with silicon sand take magnesium chloride as main raw material, its anchor leg and sealing effect are better, but its Main Problems is that set time is long, be more than 8 hours general set time, the short winter in summer is long, thereby solidify sealing process length consuming time, the time of finishing with other operation mismatches, and causes whole fireworks production process to be in nonequilibrium state, affect the production of next procedure, reduced the production work efficiency, be unfavorable for fireworks processing in enormous quantities, the problem of next is to seal preservation, quantitatively deblocking uses, otherwise the moisture absorption lost efficacy easily; The 2nd, disclosed take silicate cement as main raw material and the solid flashing composition that mixes of silicon sand and stiffening agent in the patent application, although this solid flashing composition set time is that the solid flashing composition of main raw material is short set time than magnesium chloride, do not need sealing to preserve, but its set time is still longer, simultaneously operation is also cumbersome, is not easy to hold; That the patent No. is that 200410023120X is disclosed take magnesium chloride, magnesium oxide and native powder as main raw material and the solid flashing composition that is mixed of silica sand again, although reduced the consumption of magnesium chloride, but native powder and magnesium oxide have been increased, although solidification effect is also better, but set time is still partially long, and raw materials cost is higher.
Summary of the invention
Problem for solid flashing composition existence in the above-mentioned prior art, the invention provides that a kind of not only solidification effect is good, set time is short, be conducive to produce in enormous quantities, can enhance productivity, can take full advantage of local resource again, reduce the fast set lead fixing agent of fireworks and firecracker manufacturing cost.
The fast set lead fixing agent that fireworks and firecracker of the present invention uses becomes weathering stone flour and the silicon sand of fineness more than 200 orders to mix with block land waste through the high-temperature firing ball milling, and the weight ratio of described weathering stone flour and silicon sand is: weathering stone flour 20-30%, silicon sand 70-80%.
Described silicon sand can directly be pulverized with the weathering stone and form, and also available other stone is pulverized and formed, and can also be natural fine sand, and described silicon grain fineness number is more than 50 orders.
Land waste of the present invention is the mineral substance that forms through long-term weathering, its color is assorted mutually, rill is staggered, light weight, crisp frangible powdering and granular, described land waste magnesium content is higher, secondly also contains the elements such as calcium, silicon, potassium, and it mainly originates in the surface layer of south China Pingxiang Jiangxi, Hunan Liling one band, be easy to exploitation, rich in minerals.
Using method of the present invention: first method is, first solid flashing composition of the present invention is sprinkling upon powder charge and inserts in the fireworks paper web that draws, and suitably ram-jolt is sprayed an amount of water at solid flashing composition again, solidifies fully in 2.5-3 hour under 7-9 ℃ of temperature; Second method is, before the use, adds the halogen powder (magnesium chloride) of solid flashing composition weight 1-2% in solid flashing composition, because magnesium chloride absorbs water easily, so the very fast curing of solid flashing composition, be 2.0-3 hour 7-9 ℃ of temperature lower set time.
Solid flashing composition of the present invention is mixed by the mineral substance of rich content, not only solidification effect is good for it, and set time is short, be 2-3 hour 7-9 ℃ of temperature lower set time, shortened more than 3 times set time than existing magnesium chloride solidifying agent, not only be conducive to produce in enormous quantities, improve the production work efficiency, take full advantage of again local cheap resource, reduced the manufacturing cost of solid flashing composition, the solid flashing composition manufacturing cost is compared with magnesium chloride solidifying agent cost and has been descended 1/3rd, and simultaneously the present invention is difficult for the moisture absorption, do not need sealing to preserve before the use, be convenient to store and transportation.
It is higher that the present invention takes full advantage of the land waste magnesium content, has the preferably characteristic such as water-absorbent and hardening, utilized again local abundant Mineral resources, not only shortened set time, reduced again hardener dose, reduced the fireworks manufacturing cost.
