Description

eleven

The invention relates to building materials, namely, compositions of riojiHMepOcTOHHbix mixtures, and can be used for hCh-corrosion coating of steel pipes and uncontrolled pressure pipes and free-flow pipes, as well as for repair and construction works of hydrotechnical and network structures, conduits. manufacturing of WIW and repair of drainage pipes,

The aim of the invention is to increase the strength of the polymerbet.

For the preparation of a polymer-concrete mixture, mineral aggregate — limestone flour and pre-crushed binder — a catalytic product of: (And g Ω) from a dy of a heavy netbni resin of pyrolysis of 190-LUiO V fraction, s {ol, Iac, 5), t . oli-1 ovinyl-naphtha.) pp oiu-a11 traceno-fe 1 an-1 rin resin (UJJilA l C) is mixed in a dry state, after which iodver gigg is heated at 120-160 ° C for 20-25 minutes until the homogeneous liquid is obtained a mixture, “definitely specific;;.; liquefaction. Ioluuen mass after cooling after 1.5 to 3 hours at a solid state. We can collect oligovinyl naphtha-based grinder; 1Iio11O1 antrg dheno-phenanthrene resins can also be made by heating a binder and resins separately. Heated scavengers and p) CMOJH.I alloy corresponding to metering and access; u: in a forced mixer mixer, while the temperature of the mixer should be within 11) 0-W / C. Polymer-bead mixtures produced in this way in hot air are fed into the form correspondingly 11 D1l n3, i, GJUiii, after molding iodver1 and cooling off, into normals of the oil and deformation.

Getting the proposed resin.

) A heavy pyrolysis resin was isolated from 190-360 s, which was subjected to polymerization for 5 hours in the presence of a catalyst — the complex ArSOjH 2CHjCOOH 0.5 May. % of raw material taken, where Ar is aryl (benzyl, tolyl, naphthyl, etc.). After polymerization, the catalyst complex of 110% (mol) NaOH is decomposed into a catalyst.

The salts precipitated in this way are separated by filtration, and then the polymerizate is subjected to vacuum distillation, and dark petroleum resin resins are obtained with the following characteristic:

color - dark 11 with a pearl shade;

state of aggregation is solid;

specific weight, g / cm - 1.05-1.08;

Molecules weight - 500-1000;

softening temperature within 65-85 ° С;

solubility:

in white spirit - partially;

in oil solvent - completely.

Investigated the strength properties of fine-grained polymer concrete made on the basis of shtyb - limestone flour (waste stone quarries) and OVNAFS. 71l of obtaining comparative values of the qualitative characteristics of the proposed polymer polymer with a known mixture were made of polymer-based petroleum resins and hydraulic resin.

From riojniMep6eTOHoii, cups samples were made 10 10 10 cm, beams h-А 16 cm and eights. Exemplary figurative properties of strength properties was carried out after 28 days.

The compositions and strength properties of polymeric rbetons after 28 days are given in the table.
