Description

The invention relates to poly mineral compositions used in the manufacture of chemicals from products, the lining of equipment tanks. Known polymer mineral mixture LJ including, wt.%: Urea resin 8-15 Hardener 0.3-1.8 Iron sulfate 4-9 Mineral Remaining filler The closest in technical and achievable result to the proposed is polymer Polymer L2J, including Water soluble carp ID 30-31 Catalyst for curing sulfanyl formaldehyde electrolyte 0.3-0.9 Phosphogypsum14-15 Mineral filler - andesitic flour Otherwise Disadvantage. known solutions is the low strength of the products in the initial period of hardening. The purpose of the invention is the acceleration of that strength during the curing period up to 24 hours. The goal is achieved by the fact that the floor is a mercury mineral mixture, including urea resin, curing catalyst, phosphogypsum and mineral filler, contains chlorine oxide in the quality of curing agent, with the following ratio of ponents, wt%: Urea resin Chloroxide wa-1.0-1.9 nadi 16.5-18.5 Phosphogypsum Mineral 42.6-49.5 filler 8 .2 Introduction of the hardening agent - vanadium oxychloride provides deep and complete polymerization of urea resin, which provides a stable stream round and water resistance of the polymer composition. At the same time, the obtained polymer-mineral composition has a high density and strength. For the preparation of the polymer-mineral mixture, the components used were carbamide resin (Kf-W), the hardener vanadium oxychloride, the andesite filler and the water-binding additive phosphogypsum, which were carefully dosed. The removed amount of binder was poured into the mixer, then the hardener was injected and the whole mass was mixed. Then, a pre-prepared mixture of filler and water-binding additive (phosphogypsum) was added, the resulting mass was thoroughly re-mastered. Table 1 presents the compositions of the polymer composition. For the prototype, a mixture was used, including, in May.%: Water-soluble Urea resin 30, 5 Sulfanyl-formaldehyde polyelectrolyte 0.6 Phosphogypsum 14.5 Filler-andesite 54.5 The properties specified for these compositions are presented in Table. 2. In table. Figure 3 shows the arastation indices of the compressive strength of the samples, the polymer composition in the initial stage of hardening. The samples were held under normal conditions (t 20 + 2C). The proposed polymer composition can be used in the manufacture of chemically resistant products, in the lining of containers in chemical industry and in chemically resistant tin for livestock buildings. Due to the accelerated growth of the flashiness in the initial stage of the polymer composition, the construction time is reduced.
