Abstract

The invention relates to the field of building decorative facing materials, which are used for the production of memorial goods and for decorative decoration of dwellings. The invention makes it possible to increase the weather resistance (resistance to ultraviolet and infrared radiation, increased humidity and salt mist), breaking stress during bending, and to improve the imitation of the material under marble. This result is achieved due to the additional use in a decorative polymer composition, including, by weight, h .: 60% solution of polydiethylene glycol maleate phthalate in styrene or dimethylacrythtriztilengccol 100; peroxide type initiator 2.0-5.0; cobalt naphthenate 3.0-8.0;; sand 20-240; ground brick 40-200; zinc oxide 25-40 and oligoxyhydridemethyl methylmethyleneschuksisilane 0.2-0.6. 2 tab.

The invention relates to the production of building decorative and facing materials that can be used for the production of meteoric products and for decorative decoration of dwellings.

The aim of the invention is to improve the weatherability, the destruction of flexural stress and the improvement of material simulation. under t-famore

As mineral fillers, sand: sand with an average grain size of 0.25-0.35 mm, ground; brick fractions from 300 microns to 2 mm, according to: efficient grinding of brick production waste or brick bricks: tick crushers for For the production of rosy imitation shades of artificial cams: n red baked bricks of any brands are used, to obtain: light veins on a mostly pink background I use zinc oxide in the form of a fine white powder. Oligoxyhydridemethylsilmethyleneschuksisilane is used as a stabilizer for atmospheric aging, which is a product of the direct synthesis of meth-shchlorsilanes and produced according to TU b-02 4-b-8b B vvde 10-80% solution in acetone.

As a polymeric base, 60% solutions of unsaturated polyester resin based on diethyl glycol, maleic and phthalic aggrides in styrene are used. {PN-1 or PN-12 or in dimethacryl acrylate triethylene glycol (PN-609-21K5 in which the cobalt naphtelate accelerator is included in the structure of polyester).

As the peroxide initiator, PMEC-methyl ethyl acetate or hyperysis is used.

Example 1 o A decorative composition imitating natural marble in a pattern is prepared as follows. Separately, blend the components of the main pink background and for the white cake. For this purpose, the mixer C-868 is sequentially entered, m.ch .:

The mixing of the components of the main background is carried out at a rotational speed of 200-300 rpm for the mixer blades for 15-30 minutes at room temperature.

Separately from the composition and main background, a composition of white veins is prepared, May, including:

Polyester resin 33

Cobalt naphthenate 1.6

PMEK1,0

Zinc Oxide 25

Mixing is done in 10-15 minutes.

Both compositions (main background and white veins) are combined with each other in a mixer of type C-668 at a speed of 30-100 rpm for 3-6 minutes, depending on the desired clarity of divorce, after which the total composition is placed in the appropriate form and cured either at 80 ° C in 20-30 minutes, or at 20-25 ° C in 1-1.5 hours. The compositions of examples 2-10 are prepared in the same way, the total composition of which is given in Table. 1, Depending on the required shade and pattern of the samples obtained, the ratio of the composites to the main background and the white streaks in the total compositions may be 2-5 mas. Hours. If polystyrene unsaturated polyester resin PN-609-21K is used as a polymer base, one peroxide (PMEC or hypersensitization) without cobalt naphthenate is introduced for curing, since the latter is introduced into the resin during its production.

To test samples for resistance to such factors of atmospheric aging as UV and IR radiation, humidity, and salt fog, they are placed in a climatic chamber of the Xenotest type, where accelerated aging is carried out, simulating 15 years of aging at an open test site and including 8 cycles, each of which consists of 245-300 UF-irradiation with a flux intensity of 8.4 x 10-kJ / cm in oxygen for 250 hours - periodic exposure to 98% moisture with a total duration of 120. h and a saltwater tunnel with a total duration of 100 hours, and that IR same sequential irradiation field -. 800-1000 them for 65 hours Standard samples were tested on strength index m, water absorption and a residual voltage before and after accelerated aging 8 cycles. The change in the corresponding parameter in% is estimated.

These test samples of decorative stone, prepared on the basis of the compositions of examples 1-10 and known compositions are given in table. 2,
