Abstract

The invention relates to a technology for the production of tiles. The purpose of the invention is to increase strength, reduce water absorption; tiles, as well as reducing the time of their manufacture. A method for manufacturing facing tiles is to first prepare a polymeric silicate composition by successively mixing ethyl silicate with an isocyanurate phenol formaldehyde resin and. limestone, after which water glass is introduced and stirred until a homogeneous composition is obtained, wt.%: water glass 8.9-15.8; ethyl silicate 1.9-5.3; isocyanurate phenol-resin-shaped resin 0.1-1.1; known to 77.8-89.1; The resulting composition is placed on a layer of an organic press powder with a thickness of 0.5-, 0.75 mm with a melting point of 180- 200 ° C and is hot pressed. 3 tab.

Description

The invention relates to building materials, in particular, to the technology for the production of tiles.

The purpose of the invention is to increase strength, reduce water absorption, as well as reduce production time.

The compositions of the examples 1-6 are presented in table.1.

The technological parameters of the proposed method are given in table 2.

An isocyanurate phenol formaldehyde resin is obtained by reacting 1 mol of cyanuric acid in a reactor with 0.1 mol of phenol and 4 mol of phenol formaldehyde (38% aqueous solution or formalin). Move stitches lead
