UA133904U - THERMAL INSULATION PAINTING MATERIAL - Google Patents

Abstract

Thermal insulation paint material contains a film-forming substance, the target impurities and additionally contains a filler in the form of particles of foamed polymer in the amount of 30-70% (vol.) Of the remaining components.

Description

The useful model belongs to the liquid polymer compositions intended for thermal, waterproofing and anti-corrosion protection of various surfaces of any shape, and can be used primarily in industry and construction, in particular for arranging coatings of technological equipment and pipelines, as well as metal, concrete, reinforced concrete , brick, wooden and other buildings and structures of various purposes.

A known heat-insulating paint and varnish material containing a film-forming substance and targeted impurities, in particular particles of mineral materials (GU U V.2.7-24.6- 32396113-001:2006 "Polymer-mineral composition "Keramoizol" for heat-insulating coating". The disadvantage of this paint and varnish material is the need for careful preparation surface to be painted, as well as insufficient thermal insulation properties of the resulting coating.

The closest analogue to the proposed useful model is a heat-insulating paint and varnish material containing a film-forming substance and target impurities, in particular a mixture of hollow microspheres and microspheres with a metal shell, as well as aluminosilicate microspheres, ceramics and clay (pat. of Ukraine Mo 104487 O, IPC СО90 4/02 , published on February 10, 2016.

The disadvantage of this paint and varnish material is significant complexity and cost due to the use of microspheres of different nature.

The basis of the useful model is the task of improving the heat-insulating paint and varnish material, in which its new composition and properties ensure an increase in the heat-insulating properties of the resulting coating and the possibility of recycling polymer waste.

The task is solved by the fact that in the heat-insulating paint and varnish material containing a film-forming substance and target impurities, according to the proposed useful model, the new thing is that it additionally contains a filler in the form of foamed polymer particles in the amount of 30-70 95 (06.) of the remaining components. In the most acceptable example of the material as a filler, it contains particles of a secondary foamed polymer, for example, polystyrene foam.

Additional introduction into the composition of the filler material in the form of foamed polymer particles in the amount of 30-70 95 (06.) from the rest of the components not only increases the thermal insulation properties of the resulting coating, but also provides the possibility of recycling polymer waste in the form of products made from foamed polymer and lost their consumers

From the property. In particular, as a filler, the proposed material may contain particles of a secondary foamed polymer, for example, polystyrene foam, which is a fairly widespread packaging material.

Example 1. A heat flow was directed to a galvanized steel sheet 1 mm thick using an electric lamp. After heating the sheet for 15 minutes, the temperature of its front and back surfaces was measured using thermoelectric transducers, which were equal to 40 "С.

Example 2. The method was implemented in accordance with example 1, but before its implementation, a galvanized steel sheet was covered with a layer of polymer-mineral composition "Keramoizol" of light gray color, 0.8 mm thick. The temperature of the front and back surfaces of the sheet was equal to 41 "C and 36 "C, respectively.

Example 3. The method was implemented according to example 1, but before its implementation, the galvanized steel sheet was covered with a layer of PF-133 light gray acrylic enamel, 0.8 mm thick. The temperature of the front and back surfaces of the sheet was equal to 41 "C and 38 "C, respectively.

Example 4. The method was implemented in accordance with example 3, but before applying a layer of material on a galvanized steel sheet, foamed polymer particles were added to acrylic enamel PF-133 (50 95 vol. each). The temperature of the front and back surfaces of the sheet was equal to 41 "C and 32 "C, respectively.

If the filler content is less than 30 95 (06.), the material has low thermal insulation properties, and more than 70 95 (06.) - it has insufficient physical and mechanical properties.

The thermal insulation properties of the proposed material are quite high. At the same time, universal acrylic paint and cheap filler were used for its production.

The use of the proposed cheap heat-insulating paint and varnish material increases the heat-insulating properties of the resulting coating and ensures the possibility of recycling polymer waste.
