FIELD: construction.SUBSTANCE: invention relates to production of construction materials and panels for interior surfaces of buildings. Panel for inner surface, such as ceiling tiles, which does not contain PVC materials, as a result, it is suitable for lining different buildings, including schools, residential premises, public catering enterprises and health institutions. Panel may comprise a main plate and lining material made of polymers or copolymers of polyolefin or polyester, connected with main layer. Lining material is resistant to UV radiation and has excellent ability to withstand cleaning. PVC-free lining has preferable thickness, opacity and surface roughness and texture relief, which are omnidirectional and interrupted. According to one embodiment, white-coloured PVC-free lining has preferred light reflectance. PVC-free lining is resistant to deformation under load. Furthermore, said lining has low anisotropy, that is, said lining has minimal differences in physical properties in different directions. Disclosed lining also has high shrink resistance.EFFECT: invention enables to produce a panel for inner surfaces, having environmental friendliness and functionality.9 cl, 2 dwg |
