Abstract

The invention relates to the production of materials used for modeling and modeling products. The invention allows the products to be cured at room temperature while maintaining good plasticity of the material due to the use of 0.7-2.0 wt% polyacrylamide 0.7-2.0 wt.% And polyethylene oxide mol% 1400-1600 as the polymer binder. 0-4.0 wt.%, Filler - chalk-like ground limestone (with a calcium carbonate content of 72.0-75.0 wt.%) 55.0-72.0 wt.%, Organic dye or pigment 1.5- 4.0 wt.%, An antiseptic, selected from the group including salicylic acid, borax, xylitan, 0.3-0.8 wt.%, Water ost oval 1 tab.

Description

The invention relates to the preparation of compositions used for modeling and modeling products, followed by curing at room temperature.

The aim of the invention is to provide the possibility of curing products at room temperature.

The composition uses polyac-, rilamide in the form of a technical technical gel, polyethylene oxide with mols 1400-1600, natural chalk-like ground limestone with a CaCl2 content of 72-75% by weight.

The composition is prepared as follows.

First, polyacrostamide is dissolved in water, then polyethylene oxide is introduced, with constant stirring, antiseptic is added and the resulting binder is mixed until a homogeneous mass.

The dye, part of the filler and part of the binder are ground to a fine mass, then the remaining filler and binder are added and mixed until a homogeneous mass. The composition is ready for modeling and modeling.
