Project summary

Project Tasks.

Elastic polyurethane foam widely used as simple “porolon”, has a potential fire hazard, for they catch fire easy, they are amenable to extinguishing with difficulty and form toxic product in burning. At the same time elastic polyurethane foam shows a whole number of advantages, such as unique combination of elasticity, resilience and low bulk weight. These advantages make polyurethane foam practically non-replaceable for production of soft furniture, and also attract attention to them from manufactures of automobiles, planes, ships, buses and trolley-buses, metro and electric train vans, social building furniture (hospitals, prisons, film-concert halls) and of other production which is imposed with increased requirements on fire safety of materials used.

“POLYMERSYNTHESIS” Company produces two kinds of elastic polyurethane foam – adding trichlorethyl-phosphate showing non-reactivity, and introducing of reactionable phosphorus-containing fireproof components into formulation. Both of these materials melt in fire, but they catch worse in exposure to low-caloric power sources. Nevertheless, if a melt is not removed out of combustion area, so, material burns promoting fire spread. Such a pattern takes place in fire conditions, and also in a full-scale combustibility testing.

Nowadays, in spite of increasing demand for elastic polyurethane foam with reduced combustibility, works on development of its production technology in Russia have been interrupted because of absence of necessary funding.

The proposed investigation is to determine possibility for production of elastic polyurethane foam, non-melting in exposure to fire and being unable for self-combustion at the expense of special additions. At the same time it is proposed to take polyol as a basis for production of elastic polyurethane foam, manufactured by LYONDELL Chemical firm (till 1999 – ARCO Chemical Company), USA.

Necessity for work performance under the proposed Project is evident: along with solution of technical problem of economic significance, realization of this Project with ISTC support will allow use highly qualified specialists of VNIIEF, previously engaged in development of nuclear weapon.

Project Aim.

Project aim is a development of formulation and pilot technology for production of elastic foam polyurethane of reduced combustibility at the expense of introduction of special additions – antipyren.

Project envisages:

– development of formulation and production technology for elastic foam polyurethane with optimal combination in physical-mechanical properties and combustibility;

– investigation of characteristics for materials produced and its certification;
– development of technological regimes for production of materials developed in conditions of a pilot-industrial plant.

Scientific Significance.

From the scientific point of view, task complexity is in the fact, antipyren must not only show strong fire-extinguishing effect, be non-harmful, and cheap as much as possible, but also they must not impair production technology for elastic foam polyurethane and for a complex of its principal physical-mechanical characteristics.

Practical Use.

Performed investigations will permit to propose to putting into production technology of elastic foam polyurethane with increased fire resistance meeting high requirements for its fire safety keeping physical-mechanical characteristics, showing not high apparent density (to 40 kg/m3) and cost. All this will allow use of elastic foam polyurethane as packing, sealing, decking, heat-and sound-insulating material in all the kinds of transport and social building furniture.

Work Scope.

The Project envisages determination, by Russian standards, of characteristics for elastic polyurethane foam produced on the basis of polyol of LYONDELL Chemical Co, USA – to compare material testing methods. The Project also envisages performance of works in development of formulation and production technology for elastic polyurethane foam; investigation of characteristics of a material produced and its certification, development of technological; regimes for production of elastic polyurethane foam in conditions of a pilot industrial plant; performance of market and patent investigations, and also cost estimation for a technology developed and study of possibility to put it into production.

Technical Approach and Methodology.

In the basis of technical approach there is a study of possibility to develop new for Russia technology for production of elastic foam polyurethane elements showing higher heat-insulating properties as compared to existing heat-insulating panels used in refrigerating equipment, and also study of the following characteristic set for developed materials structures: strength, heat-insulation, economical. Material study will be performed according to standards, acting in Russian Federation.
