DE627842C - Hose sealant containing rubber milk - Google Patents

Description

For the automatic closing of perforated holes Pneumatic tires have already been proposed to use rubber amldhl for pneumatic tires to be filled with an addition of ammonia or glycerin and formaldehyde. This mass should penetrate into the perforations and close them. The addition of ammonia or glycerine in the rubber milk has the sole purpose of preventing it from curdling, While formaldehyde serves as a preservative. With this means can However, the intended purpose cannot be achieved, as a separation soon occurs due to slinging the rubber milk takes place in its constituent parts, water and rubber. The rubber then forms knots, and there is no even distribution on the inside of the tube. Also will the rubber is so tough that it is no longer

ao is suitable for sealing holes in the hoop.

Furthermore, a hose sealant has become known which, in addition to rubber milk, which is mixed with ammonia, still contains animal or vegetable origin Has oils or mineral oil. The addition of oil causes an excretion of the Avoided water from the rubber milk and always kept the mass thick, however, due to the high oil content, about 500/0, this agent has a beneficial effect in some cases Lengths of air hoses,

This disadvantage is avoided by the means according to the invention. This contains in addition to rubber milk mixed with ammonia, an addition of sugar or sugar-containing milk Substances such as fruit juices. This added sugar is also used how the addition of oil prevents the water from separating out of the rubber milk and the mass always kept viscous, but this means has no effect Lengths of tubing.

Good results are achieved with a sealant of the following composition: +5

5ο0 / 0 thickened beet juice (beet herb), 500/0 rubber milk with 38 to 400/0 rubber content and an addition of 50/0 ammonia.

The thickened beet juice is first ^{heated to about 30 to 35 0} C, where it becomes thin ·; the rubber milk is then stirred in.

When using sugar, the following proportions were used: *

6 parts sugar, 1 part water, 7th parts chewy milk.

The sugar is first completely dissolved in water by heating it to the boiling point. After the sugar solution has cooled to about 30 to 35 ^° C., the rubber milk is then stirred in.

When using a sugar solution, the dietetic substances can also not contain oils (animal, vegetable or mineral oils) may be added. In this case the lifts Sugar content increases the adverse effect of the oils on the rubber of the hoses. The oil addition can be 20 to 3ο0 / 0.
