SU1244117A1 - Compound for producing basic layer of decorative facing material - Google Patents

Description

The invention relates to construction and building materials and can be used in the preparation of decorative facing materials based on glass production wastes.

The purpose of the invention is to improve the impact strength and reduce abrasion.

The composition for obtaining the base layer of decorative facing material, including broken glass, sand, additionally contains crushed clay to 0.1-5.0 mm in the following ratio of components, wt%:

Cullet 70-94

Sand 1-5

Expanded clay5-25

The introduction of a new material, iz-, ground claydite, into the bearing layer of decorative facing material provides an increase in strength and a reduction in weight loss as a result of a decrease in abrasion

when using the material

For the decorative layer, crushed glass is used in the form of glass or granules of muffled or ordinary glass (glass production waste),

PRI im p The material is obtained as follows; In the ceramic molds placed on the trolley, the bottom layer is 15-25 mm thick from a mixture of broken glass, sand and crushed expanded clay.

Then fall asleep top decorative layer of glass granules and a thickness of 5-10 mm. Trolleys with loaded ceramic molds enter the tunnel kiln, where the components are gradually heated up to 880-940 ° C, which melts the upper layer. After that, the temperature is reduced to 650-7QO ° C and maintained for 1. h. For partial crystallization

glass phase.

At 250–200 ° C, the trolleys leave the oven and the plates are gradually cooled to room temperature.

Table 5 shows the composition and properties of the material.

As can be seen from the table, an increase in impact strength and a decrease in abrasion is achieved when the content of claydite is 5-25 wt.%.

When the content of claydite is less than 5% (example 4), the resistance to impact decreases, and more than 25% (example 5) during the heat treatment of the plate, the necessary fusing of the material does not occur. In addition, the introduction of expanded clay into the composition of the material reduces the weight of the plates by 15-20%. As an expanded clay in examples 1-3, the use of expanded clay production was used - pellets of a fraction of 0.1-5.0 mm, in the remaining examples - crushed expanded clay of a fraction of 0.1-10.0 mm. Pellets with a size of 0.1–5.0 mm fill the protrusions, the gaps between the glass granules and sand grains, and, besides, they are a solid sintered substance that increases the strength of the decorative facing material. The use of smaller (0.1 mm) and larger (5 mm) claydite particles is impractical.

The obtained decorative facing material (tiles, slabs, panels) has a varied painted surface and can be used in the industrial and civil construction for cladding internal and external walls of buildings and structures, as well as floor covering. The use of the proposed composition to obtain the base layer of decorative facing material in a building structure allows to facilitate the latter and to improve the physical and mechanical properties of the facing.
