In a preferred embodiment, the waterproof cloth ball is sewn into a sphere by using flexible waterproof cloth, round holes with certain diameters are formed in the upper end and the lower end of the waterproof cloth ball, a fuze mounting seat and a lower reinforcing plate are respectively arranged on the inner side and the outer side of the round hole in the lower end of the waterproof cloth ball, the fuze mounting seat is arranged on the inner side of the waterproof cloth ball, the lower reinforcing plate is arranged on the outer side of the waterproof cloth ball, the lower end of the waterproof cloth ball is pressed by a screw, and an adhesive is sprayed in the waterproof cloth ball; the waterproof inner film is a plastic film for sealing; putting the waterproof inner membrane into the waterproof cloth ball through a round hole at the upper end, so that the waterproof inner membrane is attached to the inner wall of the waterproof cloth ball; the upper reinforcing plate and the inner lining plate compress the waterproof cloth ball and the waterproof inner membrane through screws.
The waterproof inner film material comprises, by weight, 36-44% of low-density polyethylene, 8-12% of metallocene linear polyethylene, 35-46% of thermoplastic starch master batch, 2-5% of nano titanium dioxide, 3-6% of titanate coupling agent and 1-3% of sodium stearate. Wherein the low density polyethylene is purchased from aladine P434353; metallocene linear polyethylene was purchased from exxon chemical, 3518CB. Thermoplastic starch master batches were purchased from Zhejiang macro biological technology Co., ltd., HLTPS-01. Nanometer titanium dioxide, 60nm, anatase, oleophilic, stearic acid treatment, purchased from aledine T299761. The titanate coupling agent is purchased from Hongsheng fine chemical factory in Tianchang city, and the titanate coupling agent TC-TTS; sodium stearate is purchased from merck S3381. The preparation method of the waterproof inner film comprises the following steps: the raw materials are added into a mixer at the same time, and after being uniformly mixed, a common film blowing machine is used, and a high-pressure polyethylene film blowing process is adopted, wherein the temperature is set at 140-170 ℃ for film blowing.
Preferably, the waterproof inner film comprises the following components in percentage by weight, 42% of low-density polyethylene, 9% of metallocene linear polyethylene, 40% of thermoplastic starch master batch, 3% of nano titanium dioxide, 4% of titanate coupling agent and 2% of sodium stearate. The preparation method of the waterproof inner film comprises the following steps: the raw materials are added into a mixer at the same time, and after being uniformly mixed, a common film blowing machine is used, and a high-pressure polyethylene film blowing process is adopted, wherein the temperature is set at 155 ℃ and film blowing is carried out.
Thermoplastic starch master batches are added into the material of the waterproof inner film, and the thermoplastic and rheological properties of the waterproof inner film are improved, the processing and forming properties are improved, the wet compression strength is improved, and the hydrophilicity is reduced by modifying starch. According to the invention, the thermoplastic starch master batch and the nano titanium dioxide are added into the system in a synergistic way, so that the compatibility of each component can be improved, meanwhile, the titanate coupling agent can be bent and entangled with the polymer in the system, so that the compatibility of organic matters and inorganic matters is improved, and the thermal stability of the plastic film is improved. Meanwhile, after the thermoplastic starch master batch in the system is decomposed, the plastic film can be rapidly degraded in a collapse mode, so that the biodegradability of the plastic film is obviously improved. The nano titanium dioxide has a photocatalysis effect, can provide free radical to initiate the degradation of low density polyethylene and metallocene linear polyethylene, and the biodegradability is obviously improved by selecting 60nm, sharp titanium, oleophylic and stearic acid treated nano titanium dioxide. The anatase titanium dioxide crystal structure is presumed to lead the adsorption active site to be more abundant, has higher photocatalytic activity, and has higher interfacial binding force with the polymer after being treated by the stearic acid, so that the anatase titanium dioxide is more uniformly dispersed in the system. The inventor also finds that the biodegradability can be improved by adding the titanate coupling agent and sodium stearate to act synergistically, so that the thermoplastic starch master batch and the nano particles can be dispersed in the polymer more uniformly to prevent agglomeration, but the inventor finds that the content of the titanate coupling agent and the sodium stearate is too high, so that the biodegradability of the material can be reduced, and the situation that the content is too high is that nano titanium dioxide is wrapped to reduce active sites is suspected, so that the photocatalytic performance is reduced.
Preferably, the adhesive is purchased from Guangdong-in-one adhesive Inc., HY-T160.
The waterproof cloth ball 101 is made of waterproof polyester fiber. Preferably, the waterproof polyester fiber is purchased from a fire-proof cloth factory Long Hao in Dacheng county, and the polyester fiber is used for three-proofing cloth. The three-proofing cloth produced by the Long Hao fireproof cloth factory in great city county has the functions of preventing fire, water and mildew, and the emphasis is on water resistance.
When the device disclosed by the invention is exploded, the water bag is broken by virtue of the explosion device, and the water mist is thrown to play a role in extinguishing fire. When the space above the fire scene is 15 meters away from the ground, the wind power is increased, and the turbulence is increased, so that the concentration of the fire extinguishing agent is required to be ensured, and the fire extinguishing effect is further ensured. The waterproof inner film and the waterproof polyester fiber cloth have good bonding effect, are more uniform in stress, and can ensure that the inner layer and the outer layer are crushed simultaneously as much as possible during crushing. Meanwhile, the shapes of the water bags made of different materials after the fire extinguishing agents are filled are different due to incomplete rigid molding of the water bags. According to the invention, the water bag with specific rigidity is formed by combining the two materials, the shape of the water bag after the fire extinguishing agent is filled and the explosive is combined with the mounting position, so that the dispersed water is almost horizontal by explosion, then the water cloud is more similar to a disc shape, the capability of the spray cloud for covering a larger fire surface area is increased, and the fire extinguishing effect is further improved. The inventor finds in a large number of experiments that the rigidity of the water bag is too large, the closer to a round shape, the explosion device at the bottom explodes to form obvious upward impact, the force of water cloud spreading to the periphery is reduced, but if the rigidity of the water bag is too small, the maximum diameter of the water bag is also reduced, and the radius of the water cloud is also reduced.
