SU1525184A1 - Adhesive for production of reinforced concrete articles coated with ceramic tile - Google Patents

Abstract

The invention relates to construction, in particular, to adhesives used for fixing carpets of ceramic tiles when facing reinforced concrete products. The invention makes it possible to obtain glue with a viability and biostability of 30 days, without contaminating the metal surface of the pallets, ensuring no displacement of the tile and good cleaning of the seams of the revetted reinforced concrete products from the remnants of the paper backing of ceramic carpets. The effect is achieved by using liquid glass based adhesive (45-65 wt.%) As an additive of a 10% aqueous solution of carboxymethyl cellulose (2-12 wt.%), Sodium alkyl benzene sulfonate (0.1-0.3 wt. %), oxalic or grape acid (0.2-0.8 wt.%), molasses (1-10 wt.%) and used motor or engine oil (the rest). 2 tab.

Description

The invention relates to construction, in particular, to compositions used in the production of precast concrete in the manufacture of large and small-sized products lined with ceramic tiles.

The purpose of the invention is to increase the viability and biostability, reduce ei o adhesia to the metal surface of the forms, improve the quality of the coated surfaces of reinforced concrete products.

Dp glue preparation is used; clboxyl methyl cellulose (CMP) (sodium salt of cellulose glycolic acid); sodium alkyl benzene sulfonate, oxalic acid, grape acid, starch syrup, liquid sodium glass, waste oil (engine oil or motor oil).

The glue is prepared as follows. In a prepared 10% aqueous solution of carboxymethylcellulose, oxalic acid or grape acid is dissolved, then sodium alkyl benzene sulfonate, molasses, used engine oil or engine oil are added and mixed. After stirring, water glass is introduced. Again, everything is thoroughly mixed in a forced action mixer.

The resulting adhesive composition is a viscous mass having a density of 1.30-1.39 g / cm, suitable for applying to horizontal and vertical surfaces of the mold.

The quantitative content of the components are given in table.1.

In order to obtain a glue composition for a viable and convenient dp use when gluing ceramic tiles on vertical and horizontal surfaces, it is important to first prepare the polymer component and insert the adhesive component into it, the ratio of these components should be within 1: 5-1: 20,

When ordering the introduction of liquid glass into the mixture (CMP, acid, sodium alkyl benzene sulphonate), and then working out, a liquid adhesive composition is obtained that is not suitable for achieving this goal,

By mixing all the ingredients

at the same time, the adhesive composition is also liquid and, when used, is not held on vertical

the walls of the form, resulting in the displacement of the tiles, t, e. The introduction of the components in a specific sequence influences the viscosity of the composition.

The resulting composition is applied to the cleaned form with a brush or pneumatic dispenser, and then the carpet of ceramic tiles is laid.

The thickness of the adhesive layer is 0.5-1 mm, the flow rate of the adhesive composition is 200-220 g / m. Carpets are fixed in 10-15 minutes. Then the reinforcement is laid.
