Abstract

The present invention relates to a quick leak stoppage agent for radiators, which is prepared from natural water soluble polymer such as sesbania gum, sesbania beans or seed skins and a mixture of the seed skins and cotyledon, and metal aluminium powder by processing and mixing. The present invention has the advantages of low cost, convenient use, obvious effect, etc. 10 to 30g of the quick leak stoppage agent is added to the radiator, and an engine is started for 10 minutes. A leak phenomenon can be effectively prevented. The product is especially suitable for the leak stoppage of radiators of transportation tools such as vehicles, tractors, etc.

Description

Agent to rapidly block up leakage in radiator

The invention belongs to the material that prevents that scatterer from sewing, be particularly useful for the leak stopping of gasoline, diesel motor scatterer.

The scatterer (being commonly called as water tank) of the gasoline that uses on various types of automobiles, tractor and other mechanical means, diesel motor is the vitals of engine system, and its normal operation is to guarantee one of essential condition of engine works better.Owing to reasons such as mechanical vibration, external bump and corrosion, slit or hole appear in scatterer regular meeting, cause heat-eliminating medium (water or various types of deicing fluid) to leak, influence or interrupt the work of engine.To this class fault, thoroughly the method for eradicating is repair welding, but in many cases, for example the tractor of Chang Tuyunshu automobile, field work and some other mechanical means because the scene does not have repair welding equipment, can't adopt this method, even if repair welding equipment is arranged sometimes, can not meet an urgent need.This just needs a kind of effective interim blocking method.

Traditional way is to add a certain amount of fine particulate asbestos in scatterer, and along with the circulation of cooling fluid, asbestos particles arrives leakage position, and hole is blocked.This method is more effective, but asbestos toxicity is very big, has proved that medically it is a kind of strong carcinogen, so its use is restricted.

US3984507 proposes to be used for as plugging agent with poly-propionic acid amide the refrigerating unit of sealing such as scatterer, also receives effect preferably, and nontoxic, pollution-free.But poly-propionic acid amide cost is higher, complicated process of preparation, and require to make emulsion, use not very convenient.

The present invention is directed to the deficiency of aforesaid method, propose a kind of new design: promptly in scatterer, drop into a kind of chance water swollen material, this material along with starting of pump station after the circulation of current (or deicing fluid), arrive leakage position, stop up, swelling, leakage is blocked.Require the material can not only swelling, and will have certain clinging power after the swelling, make it can not washed away by current at leakage position.The present invention has investigated the water soluble characteristic of the natural water-soluble copolymer sesbania gum of China oneself exploitation, and the behavior state in water and preparation technology's characteristics etc. find that sesbania gum possesses above-mentioned requirements fully.In view of the above, having designed a kind of is the plugging agent of main component with the sesbania gum.Use through practice, reached good effect.

Sesbania gum is by the seed sesbania beans of leguminous plants sesbania (plant name: pers Sesbania Cannabina(Retz)) make.The sesbania beans are made up of kind of a skin, endosperm and cotyledon three parts.Sesbania gum then is the peeling of sesbania beans, removes cotyledon, gets its intermediary endosperm and forms through processing treatment.Sesbania gum is a kind of non-ionic type polygalactomannan.It is to have to meet character water-soluble and hydration formation high viscosity colloidal sol.The present invention has utilized this character of sesbania gum just.In preparation process, mixture with sesbania beans kind skin or kind skin and cotyledon, be crushed to the fine particle of certain particle size, with this as center framework, sesbania gum powder is coated in its surface, adhesiving metal powder externally then, thus make the agent to rapidly block up leakage in radiator that outward appearance is irregular fine particulate.In the present invention, plant osteoderm and erect carrier function, metal-powder then is used for increasing proportion and improving outward appearance.

The preparation method of the present invention's plugging agent is as follows:

Get dry sesbania beans kind skin (or mixture of kind skin and cotyledon), be crushed to maximum particle size and be no more than 2 millimeters; Or with sesbania beans kind skin (or plant skin with cotyledon mixture) first with hot-water soak, anhydrate, be crushed to same granularity, add sesbania gum powder and suitable quantity of water (need not the adding water of hot-water soak fragmentation) then, uniform mixing also stirs, making with kind of a skin particle is center framework, the coated glue particle outside of rubber powder, dry slightly (hot-water soak fragmentation do not need drying), add metal powder again, the aluminium powder about 200 orders preferably, fully stir, metal powder evenly is attached to outside the particle, dry below 120 ℃, be no more than 1% to water content, and then use

Remove metal powder, promptly get product of the present invention.Undersized

Can give over to down usefulness.Sesbania gum powder with kind skin (or mixture of kind skin and cotyledon) ratio range is: rubber powder: plant skin (or mixture of kind skin and cotyledon)=1: 0.25～4; Ratio range is preferably: rubber powder: plant skin (or mixture of kind skin and cotyledon)=1: 0.5～2; Best proportioning is: rubber powder: kind skin (or planting skin and cotyledon mixture)=1: 1.At this moment, result of use is better, and the rubber powder consumption is less relatively.

Easy to use with the plugging agent that above-mentioned raw materials and method are made, onset is rapid, when seepage or weeping appear in scatterer (water tank), add plugging agent about the 10-30 gram, pilot engine about 10 minutes, can block slit or fine porosity effectively, prevent and sew phenomenon.If in water tank, add 10～30 gram plugging agents in advance, the generation that then can prevent to sew phenomenon effectively.

This plugging agent preparation technology is simple, the wide material sources of with low cost, main component sesbania gum.Can predict, along with industrial expansion, be that the mechanical means of power is increasing with gasoline, diesel motor, the particularly increase of transportation means such as automobile, and release of the present invention will produce huge economic and social benefit.
