The relative molecular weight of the described chitosan of above embodiment is 5000~50000.
The pH value of the described leak-stopping agent made in above-described embodiment is 4.5~7.5.
The described leak-stopping agent made in above-described embodiment, the cooling water tank of motor car engine of take is example, and using method 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, described leak-stopping agent is diffused in deicing fluid.The particulates such as the ginger powder comprised in this leak-stopping agent, hard wooden powder and metal powder can be deposited on water tank wall along with the diffusion of leak-stopping agent in deicing fluid, enter in the pore that occurs on water tank wall, sand holes, gap, and this pore, sand holes, gap are stopped up.
The pH value of leak-stopping agent of the present invention is 4.5~7.5, micro-acidity or neutrality.And deicing fluid, cooling fluid that Motor vehicles use all have certain reserve alkalinity, so be all alkaline.After this leak-stopping agent joined in deicing fluid, the weakly acidic environment of leak-stopping agent itself was neutralized, and the pH value namely raises.The relative molecular weight that comprises chitosan in leak-stopping agent of the present invention is 5000~50000, and described chitosan can be partly dissolved and in the agent of suspension leak-stopping in this leak-stopping agent.Along with the rising of pH value, this relative molecular weight is that the solubleness of 5000~50000 chitosans reduces.Static while getting off, described chitosan is partial cross-linked polymerization, and it is large that viscosity becomes, thereby effectively collaborative ginger powder and the particulate matters such as hard wooden powder, thin metal powder are further effectively blocked pore, sand holes, gap.Therefore this product can, than the general clogging larger sized gap of water tank leak-stopping agent hole, reach the effective mending-leakage in pore, sand holes, gap to 0.8~1.0mm, the effect stability of mending-leakage.
Leak-stopping agent of the present invention, chitosan its solubleness when changing into alkalescence from acidity diminishes owing to having utilized, viscosity becomes characteristic large, that be cross-linked into larger material, thereby can carry out mending-leakage to pore, sand holes, the gap of large-size, realized pore, the sand holes to 0.8~1.0mm, the purpose of the effective mending-leakage in gap, and the effect stability of mending-leakage.The preparation technology of leak-stopping agent of the present invention is simple, easy to use, also can use under the condition of not tearing machine open.
Utilize leak-stopping agent of the present invention for the water tank of the aperture of 0.8mm~1.0mm, to carry out the leak-stopping experiment to having diameter, select arbitrarily a kind of leak-stopping agent to make test sample, the efficacy parameter of leak-stopping is as shown in the table:
As can be known from the above table, the mending-leakage of this leak-stopping agent is effective, and stability is high, and can not corrode the materials such as rubber.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims 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 scope of patent protection of the present invention.
