Abstract

The material comprises (a) 1 to 50 parts by weight of acrylobutadiene styrene resin, a copolymer of vinyl chloride containing 8 to 30 per cent by weight of vinyl acetate, or butyl rubber, (b) 50 to 99 parts by weight of amorphous polypropylene and (c) 50 to 150 parts by weight of additives, especially mineral ones, e.g. zinc oxide. It is particularly suitable for producing roof cladding.

Description

SPECIFICATION Material, especially for hydro-insulating purposes, and a method of its production The invention relates to a material, especially for hydro-insulating purposes, e.g. for roof structures, and a method of its production.
For hydro-insulating purposes, especially for roof cladding, are used mostly materials and prefabricates based on asphalt which is relatively expensive. The production of these hydroinsulating materials and their application require much electric energy.
The aim of the invention is to avoid, or at least to mitigate, the above mentioned drawbacks.
The invention provides material which comprises 1 to 50 parts by weight of acrylobutadiene styrene, or of a copolymer of vinyl chloride containing 8 to 30 per cent by weight of vinyl acetate, or of butyl rubber, 50 to 99 parts by weight of amorphous polypropylene and 50 to 150 parts by weight of additives. It is advantageous to use mineral additives, e.g. zinc oxide. To this material may be added 10 to 100 parts by weight of waste pitch which remains after vacuum distillation in the production of dimethyl terephthalate, or a remaining base of production of beta-naphthol, or of polyphenylene oxide or their combination. The waste pitch, remaining after vacuum distillation in the production of dimethyl terephthalate includes 70 to 75 per cent by weight of carbon, 20 to 25 per cent by weight of oxygen and 4 to 5 per cent by weight of hydrogen.
The invention also provides a method for the production of this material in which after homogenizing amorphous polypropylene in a solution of chlorinated aliphatic hydrocarbons, e.g.
of trichlorethylene or aromatic hydrocarbons, or of hydrocarbons of a methane series, e.g.
hexane, or their combination, with a regeneration addition, all solvents are removed from the material by vacuum distillation or by a lengthy processing, viz. mechanical one. After additives have been added, the material is calendered in cold state at a temperature in the range of -5"C to +20 "C. Material produced in this way may be provided, after having been heated, with a supporting insert for improving physical and mechanical properties of the band, especially tension parameters. As a regeneration additive may be used e.g. acrylobutadiene styrene. As to hydrocarbons of methane series, it is advantageous to use e.g. hexane.
An advantage of the material according to the invention resides in the fact that it is produced mostly of waste raw materials, and in spite of this may be substituted for asphalt products for hydro-insulating purposes. It has a good drawing quality (breaking elongation), and its embrittlement temperature is well below 0 "C. The method according to the invention is simple and requires little electric energy.
When using this material for roof cladding it is possible to use hitherto known pastes, so that it may be applied without heating, which decreases energy requirements when building roof cladding.
A material according to the invention exhibits a long time stability with respect to weather influences, and with respect to a wide range of applied additives, it may be produced in many colours.
In order that the invention may be clearly understood and readily carried into effect, it is, by way of examples, hereinafter more fully described.
Example 1 On a semi-operational equipment were homogenized, in a solution of trichloroethylene, 70 parts by weight of amorphous polypropylene. In trichloroethylene were dissolved in advance 30 parts by weight of a regeneration additive, which was here represented by acrylobutadiene styrene. The homogenizing is carried out until a paste material is obtained. This paste material is made free from all solvents by means of a vacuum distillation in a vacuum at a pressure of 100 to 500 torr. This technological operation may be replaced by a lengthy mechanical processing of the paste material, e.g. by calendering, which is less advantageous as regards economy. After having obtained this semiproduct, which is free from solvents, additives are added, e.g. 80 parts by weight of titanium dioxide. Zinc oxide or barium sulphate may be added instead of titanium dioxide.Material produced in this way is calendered at a temperature of -5 "C to +20 "C; optimum production temperature is in the range between 0 "C to 6 "C.
This material provides the following mechanical properties: drawing quality (breaking elongation) 58%, yield point in tension 1.5 MPa, softening point 181 "C and embrittlement temperature -9 "C.
Example 2 Analogously to Example 1 there was produced a material consisting of two parts by weight of butyl rubber, 98 parts by weight of amorphous polypropylene, 140 parts by weight of zinc oxide and 30 parts by weight of waste pitch remaining after vacuum distillation in the production of dimethyl terephthalate.
This material provides drawing quality (breaking elongation) 153%, yield point in tension 0.26 MPa, softening point 170 "C and embrittlement temperature over --14"C.
Although the invention is described with reference to two examples, it is to be expressly understood that it is in no way limited to these examples, but is capable of numerous modifications within the scope of the appended claims.
