DE1925816C3 - Use of binders based on amorphous alpha-olefin polymers - Google Patents

Description

The invention relates to the use of colorless, colorable binders on the basis of amorphous i-olefin polymers for the production of traffic areas, floor coverings, grouting, sealing, plastering compounds and cladding elements.

Bituminous masses have proven themselves as masses of the type just mentioned. The bitumen gives Such products, however, have a black color, thereby reducing the application possibilities of the corresponding Crowds are limited. In particular, it is not possible to use the conventional, off the bitumen originating from mineral oil processing to produce light colored masses. Just such masses however, they are absolutely necessary for a wide variety of technical applications.

They are masses such as are used in accordance with the invention should come, known, in which the binder consists essentially of natural and synthetic resins (Coumarone, indene, hydrocarbon resins). However, such a binder is very much brittle and not very flexible. These properties of the resins as well as their inadequate resistance to cold of course also indicate the masses in which they are contained. In addition, the finished Masses have only a short service life due to high abrasion.

It is also known, masses of the desired type with the aid of synthetic resins, such as the Epoxies. The shelf life is similar However, bulk is due to the necessarily two-component binder very low. The known difficulties in processing two-component systems such as they represent the epoxy resin hardener systems, make the use of the appropriate compounds very disadvantageous for the purposes mentioned above.

The invention is based on the object of creating a colorless, colorable binder that for example, is able to perform the task intended for the bitumen by virtue of its ductility as well as adopting its cold resistance in the same or even more completely. The this Molding compositions containing binders should also be used in conventional bituminous processing units Be mass processable.

According to the invention, this object is achieved in that an amorphous Λ-polyolefin or an amorphous copolymer of two or more -01efins, optionally in a mixture, is used as the base material for the binder. The base material can be ^{contained in the binder with up to 1} JO weight percent, preferably 30 to 70 weight percent. In particular, atactic polypropylene can be considered as amorphous polyolefin.

The invention therefore relates to the use of amorphous polymers made from Λ-olefins and / or an amorphous copolymer of two or more -i-olefins as a base material for colorless, Colorable binders for the production of traffic areas, floor coverings, potting, sealing, Plastering and cladding elements.

According to a particular embodiment, the base material can consist of amorphous polymers from Λ-olefins and / or an amorphous copolymer of two or more »-olefins, crystalline polymers from α-olefins, crystalline copolymers from two or more \ -olefins, Resins, amorphous low molecular weight polyolefins, mineral oils, pigments, heat stabilizers and / or contain UV stabilizers.

The known inorganic or organic pigments with adequate temperature stability are used as dyes applicable.

According to the invention, products are obtained which, when tested in accordance with DIN 1995, have the following material properties result:

Penetration 10 to 200 1/10 mm,

Ductility 5 to 100 ♦ cm,

Softening point ring and ball 25 to 15O ⁰ C, breaking point according to FraP - 15 ° C and less.

Compared to the use of bituminous substances, the use of the invention The particular advantage of the binder is that it can be colored with all dyes. When using in particular of atactic polypropylene as the base material for the binder is another advantage It should be emphasized that atactic polypropylene does not become brittle and at the usual processing temperatures not scratched. Atactic polypropylene is also temperature-stable and, in particular, does not tend to Networking phenomena.

As inorganic color pigments come z. B. Consider titanium dioxide, zinc sulfide, lithopone, iron oxide, Cadmium sulfides, selenides, cobalt and manganese pigments; ah organic color pigments are those Called phthalocyanines. The already excellent light stability of the material to be used according to the invention The binder is increased by adding the pigments.

The one containing the binder.! Masses also consist of fillers, such as sand, Split, rock flour, chalk, ouarz, jute and fibrous materials. Come as heat stabilizers sterically hindered phenols into consideration. Substituted benzophenones may be used as UV stabilizers called.
