The invention relates to a material for waterproofing purposes, in particular for the isolation of building objects, in particular roofing, where high adhesion and minimal flowability are required.

At present, asphalt-based materials are used for roofing materials, which become a scarce raw material and in some cases do not even meet the requirements for stability, durability and adhesion of the covering, which is extremely cyclically stressed by weather variability. The actual processing of asphalt and preparation for its application to roof cladding is energy-intensive and shows low labor productivity. .

Recently, a number of materials based on the waste bases of chemical production have been used for this purpose, in particular waste pitch 2 for the production of dimethyl terephthalate, methyl benzoate, for the production of polystyrene and the like.

However, these materials can only be used for the particular purpose under optimal special conditions. In addition to providing sufficient resistance to sunlight, oxidation, ozone, and temperature changes, they do not provide a high adhesion to all commonly used building materials and at the same time a minimum run-off, ie below 3%.

For this reason, when applied to the articulated roofing, these materials must be supplemented with various additives which, while reducing the flowability, also reduce the required high adhesion to the commonly used building materials.

In many cases, masses on this basis also exhibit significant _B contraction and possibly reduced recovery after a long period.

These drawbacks are overcome by the waterproofing material according to the invention, which consists of 50 to 100 parts by weight of styrene waste scrap containing 30 to 70% by weight of polymers, 10 to 40% by weight of oligomers, 10 to 40% by weight. %, by weight of styrene and 0.05 to 5% by weight of inhibitors, of 30 to 70 parts by weight of the distillation residues resulting from the production of a polyester granulate containing 30 to 55% by weight, hydroxyethyl terephthalate, 12 to 35% by weight, dimer, 10 up to 25 wt.% ethylene glycol, 2 to 10 wt.% diethylene glycol, 1 to 10 wt.% trimer, 1 to 10 wt.% unidentifiable and trace substances, 30 to 80 wt.% parts of solvent naphtha, toluene or chlorinated hydrocarbons such as trichlorethylene or perchlorethylene, 40 to 90 parts by weight, parts by weight of acetone, 10 to 30 parts by weight, parts by weight of dibutyl phthalate, 20 to 60 parts by weight, parts by weight of vinyl chloride copolymer containing 8 and 30 wt, percent vinyl acetate and 5 to 20 wt. Parts of a stabilizer, such as zinc or aluminum powder.

The composition according to the invention is based on two waste bases which have not previously been treated correspondingly and which have been disposed of by incineration to produce environmentally harmful flue gases.

This material does not exhibit a contraction that would cause cracks of the waterproofing coating, it is applied cold, so that it does not require energy costs and does not need to add additives and it is possible to control adhesion and flowability of this material according to specific type. application. In many cases, this material replaces asphalt products, which are considerably more expensive and because of its properties this classic material for waterproofing purposes surpasses many qualitative parameters.

The exemplary composition of the composition of the invention is described including the basic properties achieved in the following examples.
