Host contraceptive and fat compositions

The present invention relates to strongly basic metal containing greases and rust preventives and in particular Compositions of this type that have low tack and have good weathering properties.

Normal oil solutions of an oil-soluble dispersant salt containing a basic alkaline earth metal salt or a complex thereof dissolved or dispersed.Such compositions have been prepared by several procedures, some of which comprise two basic process steps, in which a mineral oil solution of a carbonized, basic alkaline earth metal salt is initially formed which is then in the second stage is treated with an active hydrogen compound to give the fat compositions. A typical two step process for preparing such grease and rust preventive compositions is described in U.S. Patents 3,242,079 and 3,372,115. Other procedures involve a single step wherein a mixture of an oil soluble dispersant, nonvolatile carrier, water , Alcohol and alkaline metal carbonate complex is heated under controlled conditions to effect conversion to fat. Typical operation of this type is described in US patent application Ser.

Greases and rust preventive agents of the type described mostly contain a large amount of a non-volatile one Thinner oil, which acts as a plasticizer and emollient

acts medium. The calibrating fats and root contraceptives are therefore relatively soft and sticky. When these compositions are used as surface coatings for metals, such stickiness is undesirable for both aesthetic and safety reasons. Another problem that has arisen with rust preventive agents of the type described is the tendency for films or coatings deposited with the agents on metal surfaces to become chalky and brittle and eventually to peel off and expose the metal backing when the coating is used for extended periods of time Periods of time is exposed to changing weather conditions.

It has now been found that certain important characteristics of the grease and rust prevention compositions of the type described can be improved when the chemical to halt the presently known compositions will be modified, either by the fact that the usually introduced non-volatile diluent oil or carrier material substantially _s removed or more importantly and preferably by the fact that certain organic, weathering and tack-reducing materials are added to the composition. The latter materials can be incorporated into the grease and rust preventive compositions in lieu of all or part of the non-volatile diluent oil or carrier material usually incorporated, or the weathering and tackiness-reducing materials can be added in addition to such non-volatile diluent oil or carrier material.

Carbonized, basic alkaline earth metal as produced “The salt is produced by carbonizing a mixture of an alkaline earth metal salt of a sulfonic acid and an alkaline earth metal base.” Theoretically, it is assumed that a carbonate complex of the alkaline earth metal and the acid salt develops in the process. The carbonized mixture is characterized by having a "metal ratio" of at least 4.5 ". The metal ratio is defined as the ratio of the total chemical equivalents of the metal in the metal salt to the chemical equivalents of the metal which is in the form of a normal or neutral salt of the sulfonic acid used.

The carbonate compound is preferably present in the colloidal dispersion in the form of particles formed in situ with an average diameter of 0.25 / u or less.

Fat compositions resulting from the one- and two-step processes described generally contain at least 20 wt. # Of a non-volatile mineral oil diluent or carrier material, about 10 to about wt 45 wt .- ^ of the basic metal carbonate compound or the basic metal carbonate complexSo The specific types and properties of these components are described in detail below. When the fat compositions are dissolved in a light hydrocarbon solvent such as Stoddard's solvent, they can be spray or brush applied to metal surfaces to provide relatively thick protective coatings with good host control properties. The salt spray corrosion study of metal surfaces coated in this way shows that the films or coatings protect the metal thoroughly against corrosion by the mist over long periods of time.

It has now been found, however, that the corrosion-promoting conditions present in the salt spray test, which is widely used, affect sensitivity; of metals against corrosion provides no useful indication of the ability of films or coatings of the type described to withstand long exposure to the open air or long exposure to the weather In Oklahoma they have been kept in the open for months facing south, a swelling or exudation of the anti-rust film occurs, accompanied by the onset of corrosion, since the "si -. ^ = lent, brittle coating flakes off and is lost" J) sa same exudation and peeling of the Übecsugea fee-L ^ s in a period of about 2 to 4 months in the

It has now been found that the cause of this exudation and peeling of the rust prevention 3filraee or - Coating in the loss of the non-volatile diluent oil or carrier material used and also in the Loss of dispersant lies. This leads to deposition of calcium carbonate (lime) on the metal surface. The mechanism for this lime formation or excretion and for loss of diluent oil and sulfonate dispersant appears to the evaporation and oxidation of the oil and the emulsification of the oil-soluble sulfonate saline to be attributed to rainwater. The conditions that cause the limescale formation described and the (coating loss cause are the alternating periods of high temperature and intense sunlight and with violent intermittent rain that occurs when there is prolonged, south-facing exposure in the open air.
