BUILDING COMPONENT AND METHOD OF MANUFACTURE THEREOF Russian patent published in 1997 - IPC

FIELD: manufacture of building materials. SUBSTANCE: invention relates to constructional objects building parts possessing required decorative and/or shock-absorbent properties and being pleasant by touch. Component of invention has a massive foundation made of saturated polyester including terephthalic acid units or its mixture with another thermoplastic polymer taken in amount up to 50%, advantageously 10-40% based on foundation weight, or a mixture of saturated polyester with reinforcing and/or target additives, and decorative facing. The latter is made from one or several layers determining optical and/or organoleptic properties of the component with face layer being made from a textile material based on polyethyleneterephthalic acid saturated polyester. Foundation is inseparably jointed with adjacent decorative facing layer, and all layer of the component are capable to be used once more for manufacturing polymer constructional object based on the component possessing required mechanical properties. Decorative facing may be composed of 1-3 layers, the face one being textile material and one of remaining layers being made from polyester foam. All the facing layers are glued or welded to each other. Massive foundation may be made from recyclization product of saturated polyester or a polyester containing corresponding recyclization product. The component is manufactured by way of inseparably joining massive foundation and decorative facing using a conventional technique applicable to thermoplastic polymer materials, for example, by molding under pressure of the foundation smelt onto reverse side of decorative facing. EFFECT: improved building possibilities. 9 cl
