Description

ANTI-ICE CREAM

Technical field

The invention relates to compositions for molding building and finishing materials, such as tiles, tiles, slate, which provide a reduction in adhesion between ice and various surfaces and protect against atmospheric factors, and can be used to combat icing of buildings, structures and structures, in particular, roofing, cladding of buildings and structures, pavements.

State of the art

To date, no known composition for molding products that provide a decrease in adhesion between ice and the coating itself. To combat the ice, various anti-icing fluids and paints are currently used, which are applied to the outer surface of the coatings of buildings, structures, aircraft.

So, from the patent of the Russian Federation NQ2183216 (published 10.06.2002), a composition is known for treating an aircraft with the aim of preventing icing, which contains an aqueous glycol or glycerin solution, thickened with a polymer thickener and / or its salt after neutralization, taken in an amount sufficient to thicken this composition to a state that ensures its adhesion to the surface of the aircraft, which is at rest, and, in addition, ensuring its removal under the action of shear forces of the wind during take-off, and the specified thickener includes the following components (wt.% of total

0 £ β

weight of the latter): (A) 1-99.9% of one or more - "- unsaturated carboxylic acids with a monoethylene bond; (B) 0-98.9% of one or more unsaturated monomers with a monoethylene bond; (C) 0, 1 -99% of one or more unsaturated monomers with a monoethylene bond, preferably macromonomers containing at least one side hydrophobic moiety; and (D) 0-20% of one or more unsaturated monomers with polyethylene bonds; and said composition includes the following components, by weight .% of the total weight of the composition: at least about 40% of one or more glycols or glycerol or mixtures thereof; at least about 0.05% of said thickener; a neutralizing agent including sodium hydroxide in an amount sufficient to provide a pH of at least about 7.1; surfactant a substance that forms an associate with a thickener in an amount sufficient to enhance the thickening effect of the thickener; optionally a corrosion inhibitor in effective amount; (6) optionally one or more dyes; and water - the rest.

From the description of the UK patent N22050398 (published 01/07/1981) known mixture in the form of a paste that reduces or prevents the formation of ice, which contains polyethylene glycol and a mixture of two or more low molecular weight alcohols.

From European patent N20339583 (published 02.11.1989), an anti-icing coating is known which contains a copolymer having a hydroxyl or hydroxyl group and a chemically active group other than hydroxyl, and comprising an ether monomer of fluoroolefin and a vinyl monomer, a silicon compound.

In addition, a known composition for de-icing coatings, which contains an organosilicon polymer binder consisting of polydimethylphenylsiloxane and polydimethylsiloxane and toluene, talc or a mixture of talc with belite and / or barite and oxides and / or salts of transition metals in the following ratio, wt.%:

organosilicon polymer binder - 30 - 40, talc or a mixture of talc with belite and / or barite - 9 - 18, oxides and / or salts of transition metals - 6 - 15, toluene - the rest (RF patent N ° 2156786, published 09/27/2000) .

Also from the description of the USSR copyright certificate Ns1171492 (published

08/07/1985) the anti-icing composition is known, which includes the product of combining polypichlorohydrin diglycidyl ether with epoxy resin, an amine hardener, which is used as triethylenetetraaminomethyl phenol, sodium chloride and aerosil, in the following ratio of components, parts by weight of the product of the weight of the epoxy epoxy dihydrino dihydrin - 100.0

triethylenetetraaminomethylphenol - 21, 8-26.0

sodium chloride - 50.0-100.0

Aerosil - 1, 0-3.0.

This composition by a general decision can be adopted as the closest analogue to the patented.

The disadvantages of the known composition due to its properties. The patented product refers to a paint containing epoxy resin, when applied to a surface protected from ice, it will lead to uneven application due to its dripping under gravity, therefore, when processing vertical surfaces, the upper part of the structure or building will be less protected by compared to the bottom. Paint is preferable to use only for protection of horizontal surfaces. This product has a rather long drying period, from a day or more, provided that the conditions are favorable for this - dry weather, ambient temperature - more than +15 degrees. When the temperature rises above +25 degrees, the applied coating will deform and drain. Also, the service life of such a layer is quite short-lived, less than 6 months, and requires constant updating. Thus, the use of the composition known from the copyright certificate is rather limited. In addition, the use of toxic substances, the product of the combination of diglycidyl ether polyepichlorohydrin with an epoxy resin and triethylenetetraaminomethylphenol, will lead to environmental pollution when using this composition.

Disclosure of invention

The technical result of the patented invention is to obtain an anti-icing composition intended for molding building and finishing materials, resistant to temperature extremes and having high strength, durability and environmental friendliness.

Also, the technical result is to simplify the production technology of the anti-icing composition, reducing the drying time to 15-20 minutes.

The claimed technical result is achieved through the use of an anti-icing composition, including polyester resin, sodium chloride, sodium bicarbonate (baking soda), hardener and accelerator, in the following ratio of components, wt.%:

polyester resin - 17-60,

sodium chloride - 79.5-38.5,

sodium bicarbonate - 0.5-0.7,

accelerator - 1, 5,

hardener - 1, 5

It is preferable to use cobalt octoate (OK-1, OK-2, OK-3) or hyperit as the hardener. Cyclohexanone peroxide may also be used. It is desirable to use Butanox-M 50 as an accelerator. In addition, it is possible to use cobalt, dimethyl- or diethylaniline, thiourea, ascorbic acid, Sn, Mn, Co compounds as an accelerator.

Any polyester resins can be used as the polyester resin, including those based on polyalkylene glycol maleates and polyalkylene glycol golfumarates and unsaturated monomers, mainly styrene, methyl methacrylate, allyl compounds or oligoester acrylates.

However, it is preferable to use orthophthalic unsaturated polyester resins of the following types: Arkpol 10 TP, Arkpol 20P, Arkpol 50, Boytek BRE 31 OTP, s 2011/000423

Boytek BRE 330SA, Boytek BRE 320K, Boytek BRE 323KX, Boytek BRE 450, Boytek BRE 328, Boytek BRE 315, PN-12, acrylic polyester resins, for example, Technacryl brand. These resin brands are used in the manufacture of molds for food products and liquids, and also contain an accelerator and hardener in their composition, so their additional introduction is not required.

The choice of polyester resins in the composition is due to their increased water resistance and environmental friendliness.

Sodium chloride is used in the patented composition not only as an agent that reduces the freezing point, but also, as was found during testing, sodium chloride plays the role of a filler in the patented composition. In this regard, the additional introduction of a filler is not required.

Sodium chloride can be used in the form of table, sea or rock salt.

In addition, an unexpected effect of accelerating the melting of the ice crust at low temperatures, below -30 ° C, using sodium bicarbonate was discovered. When sodium bicarbonate was added to the composition, when it came into contact with water, formed when the ice crust melts on the coating surface, carbon dioxide was released and the upper layer of ice crawled.

Also, with the aim of whitening the composition, titanium dioxide in an amount of 0.7-1, 0% wt.

The composition is obtained by mixing the components in the mixer at a temperature of 18-20 ° C, mixing is carried out until a homogeneous mass is obtained for about 5-20 minutes, depending on the volume of the composition being mixed, after which the mass is poured into molds and pressed.

From the obtained composition, a sample of dimensions 10.16 x 25.4 x 1 cm was obtained, which was tested for abrasion resistance, impact resistance, structural integrity.

The abrasion resistance test was carried out on a standard testing machine up to 3000 cycles.

Test data and a comparison of the results with the results of similar tests of natural marble conducted by the Institute of Concrete are shown in table 1.
