PROCESS FOR MAKING INFUSIBLE ASPHALT HASSES OF HIGH ELASTTCITY.
Io Drawing. Application filed April 28, 1928, Serial Io. 273,788, and in Austria April 19, 1927.
The invention relates to a process for making infusible asphalt masses of high elasticity.
The low elasticity of various asphalt kinds known up to the present-natural asphalt, mineral oil asphalt, pit coal and brown coal asphalt'has been considered for a long time past to be a drawback in different uses. This has led to investigations which made it posby which asphalts of difie'rent origin may be perfectly intact.
so improved as to obtain almost rubber-like consistency. This process consists in treating asphalt with Chinese wood oil in the heat masses being thus obtained, which without any after-treatment by vulcanization, such as sulphurizing, treatment with sulphur chloride or formaldehyde, are capable of being shaped and keeping the shape once obtained even when exposed to a temperature up to 300 C. and more, their elasticity remaining Owing to this fact the masses thus produced are suitable for various purposes especially where it is preferable to use products having high elasticity and resistance against heat and weather, for instance as floor covering material in road building, roof covering, as insulation and packing materials and so on.
The quality of the products thus prepared depends to a large extent on the kind of raw materials which are used that is to say on the sort of the asphalt and of the Chinese wood oil the latter being a commercial product of a rather variable character. Moreover the quality ofthe final product depends on the ratio of mixing of the two components; furthermore the temperature and duration of the heating are of essential influence as re- 1 gards the hardness, strength and elasticity of the asphalt masses obtained by the treatment according to the invention. The temperature may be raised up to 300 C. according to the heating being performed more or less s'peedlly the result aimed at is obtained in a shorter or longer time. It is possible to influence the quality of the final product by appropriately considering and varying the above-mentioned features; moreover the process may be assisted and accelerated by application of known condensing agents such as aluminium chloride, zinc chloride, ferric chloride, copper chloride or phosphoric acid and others; these agents being either added to the asphalt or the mixture of asphalt and wood oil.
To the asphalt mass prepared according to i the above process there may be added dif ferent filling material, such as sand, gravel, broken stones, saw dust, cork refuse, talcum, asbestos" and in some cases waste rubber in difierent quantities, such additions being used generally for certain purposes for instance in road building, floor covering materials and so on. The mass may also be spread on pasteboard, card board, textiles or twists of hemp or cotton may be impregnated therewith and used for packing purposes.
By calendering the mass may be rolled to elastic plates if desired on a textile support to yield a product resembling linoleum.
Ewample 1.--50 parts of'natural asphalt.
(gilsonite) are heated with 50 parts of Chinese I wood oil for an hour the'temperature being 270. C. at the end of this time; the mixture gelatinizes when this temperature is reached and forms an elastic, strong mass.
Example 2.-50 parts of petroleum as halt are heated for an hour with 5 parts of err1c chloride (FeCl up to 300 C. whereupon 50 parts of Chinese wood oil are added, the heating beinghcontinued until coagulation will occur. e resulting material is infusible and of high elasticity.
Ewmmple 51-60 parts of asphalt are heated with 5 parts of aluminium chloride (AlCh) for an hour up to 280 C., whereupon 40 parts of Chinese wood oil are added. Upon further heating the mixture gelatinizes after a few minutes and yields an infusible, elastic ma- .terial as in Example 2.
Example 4-70 parts of asphalt are heated With 5 parts of zinc chloride (ZnCI for an hour to 280 C., whereu on' 30 parts of Chinese wood oil are addedi After 15 to 20 minutes the desired elastic mass is obtained which is infusible even at 300 C.
Example 5.-One of the mixtures described in Examples 1 to 4 or some other mixllO ture of asphalt with Chinese wood oil with or without addition of other metal chlorides is heated, poured into moulds before coagulation occurs and the reaction allowed to become complete by further heating. Thus shaped articles are obtained which are infusible and of high elasticity.
What I claim is 1. A process for producing asphalt masses of high elasticity which comprises heating a batch of asphalt containing not more than 10% of a condensing agent comprising a salt from the group comprising ferric chloride, aluminum chloride and zinc chloride to a temperature not greater than 300 C., and upon the mixture reaching the desired temperature adding a portion of Chinese wood oil not to exceed the amount of asphalt used and continuing the heating until coagulation occurs.
2. Hardened masses of high elasticity comprising the product obtained by heating a mass of asphalt with a condensing agent from the group comprising ferric chloride, aluminum chloride and zinc chloride up to a temperature not higher than 300 C. and adding a quantity of Chinese wood oil to the heated asphalt, the amount of said Chinese wood oil not exceeding the amount of asphalt heated, the resulting mixture being maintained at a heated temperature not to exceed 300 C., until the said masses of high elasticity ensue.
In testimony whereof I afiix 1n signature.
