Abstract
An adhesive mixture of synthetic polymers, for encapsulating amianthus manufactures, consisting of synthetic polymers like styrol, butadiene and glycols, mixed in water at percentages from 3 % to 20 % with branched reagent charges, like cement, calcium carbonate and cellulose fibres, so as to be applied to the manufacture by spraying or by means of a plaster sprayer.
Description
"AN ADHESIVE MIXTURE OF SYNTHETIC POLYMERS FOR INCAPSULATING AMIANTHUS"
The present invention concerns an adhesive mixture of synthetic polymers, for incapsulating a m i a n t h u s manifactures.
The serious and current tecnologic problem of t h e discharge of cement-amianthus manifactures, like eternit, which degrade in time, which must be scraped off, washed or treated with particular substances ( like primer), with the consequent removal of the volatile amianthus particles which have proved to be extremely dangerous for health, before they are conglobated in the cement.
It is the aim of the present invention to realize a mixture to be sprayed onto the surfaces to be incapsulated, without performing before any preparation, even with a vegetation of dried mushrooms, obtaining a strong adhesion to the manifacture so as to obtain the following results:
- restructure of the degraded eternit, re-establishing its primary features of resistance to charge;
- waterproofing of the treated surface,
- incapsulating of the free amianthus fibres, so that the amianthus plates do not show any flaking, they remain whole, nor do they release amianthus particles, even if
2
they have been subjected to ageing tests at 400 cycles (corresponding to about 20 years).
The aim set forth is reached with the adhesive mixture according to the present invention, consisting of synthetic polymers like styrol, butadiene and glycols, mixed in water at percentages from 3% to 20% with branched reagent charges, like cement, calcium carbonate and cellulose fibres, so as to be applied to the manufacture by spraying or by means of a plaster sprayer, obtaining an efficacious incapsulating.
The advantages of the mixture according to the present invention are many and relevant:
- the presence of polymers in the mixture gives t h e treated manufacture a good waterproofing and flexibility and also a relevant resistance to temperature changes and to the erosion of atmospheric agents;
- once it has been applied onto the eternit coverings degraded by time, it absorbs the amiathus particles freed by ageing and re-establishes the primary strength of the manufacture;
- possible holes or tears are restored by applying patches of TNT (tissue-non-tissue), shaping it onto the eternit and spraying onto it the mixture, thus forming a single body with the support.
3
The present invention will be described more in detail hereinbelow by an embodiment that may be realized in the following proportions in weight of component aggregates:
- calcium carbonate or fine monogranular sand from 0 to 0,6 mm kg 300
- 325 or 425 cement kg 100
- mixture of synthetic polymers (styrol, butadiene and glycols) kg 40/50
- water kg 10
- glass- and polypropylene fibre
kg 0,222
In possible variants according to the present invention, the weight of the mixture of synthetic polymers may also exceed the mentioned limit of 50 kg remaining efficacious, even if in said case an increase in weight would mean only an increase in costs.
