Description

The invention relates to the manufacture of building products by extrusion molding.

The known building composition-concrete mix 1, including

Mineral in the grub 15-60 Filler 5-7

Hydrolyzed polyacrylonitrile 0.07-0.9 Caustic soda 0.01-0.2

Water Rest

Closest to the offer is a mortar comprising, in wt.%:

Gypsum 47-70

Methylcellulose 0.3-1.5 Quartz sand 4.5-20 Reinforcing fibers 5-30

The molasses of the post-seasoned bard 0.2-2.0. The disadvantages of the known solutions are the low temperature of the molding solution, the low elasticity and the increased roughness of the products.

The purpose of the invention is to increase the temperature of forming a solution, improve elasticity and reduce product roughness.

The goal is achieved by the fact that a mortar for extrusion molding of products, including mineral stoneware, a filler, and a substance and groups including molasses post fermentation bard, methane mash, salicylic acid-formaldehyde sodium salt, additionally contains the alkaline hydrolysis product of polyacrylonitrile and a stage of the polyacrylonitrile formula. -80% and molecular

mass (1-6) 10 with the following ratio of components, wt.%:. Mineral in the gnawing 36-90 Filling7,3-59,9

A substance from the group including molasses post-yeast bard, methane mash,, sodium salt of copolymer of salicylic acid with formaldehyde. 0.1-2.3 The product of alkaline hydrolysis of polyacrylonitrile with a degree. Saponification 40-80% and molecular weight (1-6) -10 0.5-4.0 Gypsum, Portland cement, gypsum-cement-pozzolanic or lime-silica-cement can be used as a mineral sticking agent. Fillers are typically a mixture of a dispersed and fibrous component, for example quartz sand, fly ash and asbestos, cellulose and stellate fibers. Well-known substances are used as a hydration regulator, such as one stripped off of a postrothroth bard, methane stalk, GRP-1 (sodium salt of a copolymer of salicylic acid with formaldehyde), etc.

The method of preparation of the solution is carried out as follows.

All the dry components that make up the solution are thoroughly mixed to a homogeneous mass and filled with an aqueous solution of additives.

40 Table. 1 and 2 shows the composition of the mixtures and their properties.
