Title
(EN) FOAMABLE COMPOSITION, PROCESS FOR ITS PRODUCTION, RIGID FOAM, AND PROCESS FOR ITS PRODUCTION
(FR) COMPOSITION EXPANSIBLE, PROCEDE POUR SA PRODUCTION, MOUSSE RIGIDE, ET PROCEDE POUR SA PRODUCTION
Abstract
(EN)
A foamable composition, a process for its production, a rigid foam produced from the foamable composition, and a process for its production are disclosed. The foamable composition comprises (A) a vinyl chloride resin, (B) an inorganic substance containing inorganic fibers of 1 $g(m)m or more in diameter, (C) a solvent which shows a maximum torque of 4 to 25 N.m as a mixture of 100 parts by weight of a vinyl chloride resin of an average degree of polymerization of 2400, 100 parts by weight of the solvent, and 6 parts by weight of dibasic lead stearate when kneaded at a rotation of 30 rpm while raising the temperature using a plastograph, and (D) a decomposable foaming agent. This rigid foam does not require asbestos and is therefore excellent in safety and sanitation of human beings. In addition, it gives less heat and smoke, produces a less amount of poisonous gas, and undergoes less deformation upon combustion, shows excellent dimensional stability in use at high temperatures, that is, shows excellent heat resistance and, even when forcibly burnt, does not cause harmful ashing which maycause degradation. In addition, it is inexpensive.
(FR)
Sont décrits une composition expansible, un procédé pour sa production, une mousse rigide produite à partir de la composition expansible, ainsi qu'un procédé pour sa production. La composition expansible comporte (A) une résine de chlorure de vinyl, (B) une substance inorganique renfermant des fibres inorganiques d'un diamètre égal ou supérieur à 1 $g(m)m, (C) un solvant qui présente un couple maximal de 4 à 25 N.m sous forme d'un mélange de 100 parties en poids d'une résine de chlorure de vinyl d'un degré moyen de polymérisation de 2400, 100 parties en poids du solvant et 6 parties en poids d'un stéarate de plomb dibasique en cas de malaxage à une vitesse de rotation de 30 tours/minute accompagné d'une élévation de la température au moyen d'un plastographe, et (D) un agent moussant décomposable. Cette mousse rigide n'exige pas d'amiante et est par conséquent excellente du point de vue de la sécurité et de l'hygiène des êtres humains. En outre, elle dégage moins de chaleur et de fumée, produit une quantité moindre de gaz toxiques et subit une déformation moindre lors de la combustion, présente une excellente stabilité dimensionnelle en service à des températures élevées, c'est-à-dire, présente une excellente résistance à la chaleur et, même en cas de combustion forcée, ne produit pas de cendres nocives susceptibles de provoquer une dégradation. En outre, elle est bon marché.
