The fineness of said ginger powder is 24～60 orders, and the fineness of said redwood powder is 40～80 orders, and the fineness of said copper powder and aluminium powder is 120～300 orders.
The relative molecular weight of the said chitosan of above embodiment is 5000～50000.
The pH value of the said leak-stopping agent that makes in the foregoing description is 4.5～7.5.
The said leak-stopping agent that makes in the foregoing description is an example with the cooling water tank of motor car engine, and the method for use and the result of use of leak-stopping agent of the present invention is described.At first this leak-stopping agent is joined in the deicing fluid of antifreezing water tank of motor car engine, said leak-stopping agent is diffused in the deicing fluid.Particulates such as the ginger powder that comprises in this leak-stopping agent, hard wood powder and metal powder can be deposited on the water tank wall along with the diffusion of leak-stopping agent in deicing fluid, enter in the pore that occurs on the water tank wall, sand holes, the slit, and with this pore, sand holes, slit obstruction.
The pH value of leak-stopping agent of the present invention is 4.5～7.5, micro-acidity or neutrality.And deicing fluid, quench liquid that Motor vehicles use all have certain reserve alkalinity, so all be alkaline.After treating that this leak-stopping agent joins in the deicing fluid, the weakly acidic environment of leak-stopping agent itself is neutralized, and the pH value promptly raises.The relative molecular weight that comprises chitosan in the leak-stopping agent of the present invention is 5000～50000, and said chitosan can be partly dissolved in this leak-stopping agent and in the agent of suspension leak-stopping.Along with the rising of pH value, this relative molecular weight is that the solubleness of 5000～50000 chitosans reduces.Static when getting off, the then partial cross-linked polymerization of said chitosan, it is big that viscosity becomes, thus effectively collaborative ginger powder is further effectively blocked pore, sand holes, slit with particulate matters such as hard wood powder, thin metal powders.Therefore these article can stop up larger sized slit hole than general water tank leak-stopping agent, have reached the effective mending-leakage in pore, sand holes, slit to 0.8～1.0mm, the effect stability of mending-leakage.
Leak-stopping agent of the present invention; Owing to utilized that chitosan diminishes in its solubleness when acidity is changed into alkalescence, viscosity becomes big, be cross-linked into the characteristic of bigger material; Thereby can carry out mending-leakage to pore, sand holes, the slit of large-size; Realized pore, the sand holes to 0.8～1.0mm, the purpose of the effective mending-leakage in slit, and the effect stability of mending-leakage.The preparation technology of leak-stopping agent of the present invention is simple, and is easy to use, under the condition of not tearing machine open, also can use.
Utilize leak-stopping agent of the present invention to carry out the leak-stopping experiment to having diameter for the water tank of the aperture of 0.8mm～1.0mm, select for use a kind of leak-stopping agent to make test sample arbitrarily, the efficacy parameter of leak-stopping is as shown in the table:
Can know that from last table the mending-leakage of this leak-stopping agent is effective, stability is high, and can not corrode material such as rubber.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes description of the present invention to do; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
