NEW DECORATIVE FACING MATERIAL

The new decorative facing material made from foamed cross-linked vinyl chloride polymer and its production method has been developed. Manufactured in the form of a honey-comb monolith, the facing material is light and environmentally friendly. Its properties being similar too those of wood and leather, give it an obvious edge on the foreign-made analogs.

The new material can be used in manufacturing furniture, for interior lining of automobile, aircraft, ships, railway cars, and rooms. The emulsion polyvinyl chloride serves as its source material. The found processing conditions permit foaming avoiding the use of commonly applied foaming agents, and cross-linking without using cross-linking agents. Owing to the fact that the polyvinyl chloride dehydrochlorizing points are dissipated at the molecular level, the proposed method excludes any limitations of uneven foaming. The foaming level is easily technologically controlled.

The closest analogs of the new material are polyvinyl chloride films or sheets, natural veneer and leather.

The main properties of the new material are:

  • it is environmentally friendly;
  • self-extinguishing;
  • antistatic;
  • sound and heat insulating;
  • corrosion resistant;
  • biologically stable;
  • adhesive by most commonly used glues;
  • it withstands temperatures from -50° to +70° C
  • suitable for dry and wet cleaning;
  • can be cut, nailed and stuck.

The high competitiveness of the new facing material is ensured by the following factors:

  • virtual absence of components (less than one percent);
  • low material consumption (density: 0.3-0.8 g/cm3);
  • simple production technology (the production line is based on conventional equipment);
  • a range of properties similar to those of natural materials.

The ratio between the production cost of 1 kg of the new material and that of 1 kg of primary product (which determines the added value and the profitability of the proposed technology) is 2.7, as compared with 3.9-5.5 representing the ratio between the production cost of 1 kg of polyvinyl chloride film (used in furniture facing) and the cost of 1 kg of the used primary product.

The estimated price of new facing material will be $2.8-3.3 per m3. Compare prices for other materials: polyvinyl chloride film (furniture lining) costs $2.5- 4.0 per m3; sheets of foamed polyvinyl chloride (Simona) costs $13.7 per m3; imitation leather costs $3.8 per m3; sheets of veneer from natural oak (unstained and unvarnished) costs $1.6 per m3.

Chipboard faced with natural varnished veneer costs $20.5 per m3, while faced with the new facing material it will be $16.6 per m3.

The new material was exhibited at international fairs (Birmingham, Novosibirsk and Nizhny Novgorod). Furniture manufacturers, building and architecture companies were highly interested in the material at its estimated price.

Based on the new facing material, the production of roofing, flooring materials and other sheet-shaped building materials can be launched.

Thus, the developed material manufactured from foamed polyvinyl chloride has evident advantages in its economic indices, as compared to best world analogs.

First batches of this material have been industrially manufactured. The facing material and its production know-how are protected by five Russian patents. Moreover, it is being patented in 17 European countries.
