ABSTRACT
The article describes the results of experimental studies on the analysis and improvement of existing methods for
determining the thermal conductivity of liquid composite heat-insulating coatings.
KEYWORDS
Energy efficiency, thermal insulation material, thermal conductivity, microsphere, thermal insulation paint, stationary
method, non-stationary method, thermocouple sensors.
INTRODUCTION
One of the most important and priority tasks in the
modern construction industry is to save energy by
reducing the energy consumption of buildings. In
particular, the efficient use of thermal energy in
buildings, heat pipelines, energy networks and other
areas is one of the priorities. This is due to limited
energy resources, high energy costs and the negative
impact on the environment as a result of its
production. The use of modern thermal insulation
materials, including liquid energy-saving heat-
insulating coatings, is an important study in the current
era of rising prices and the scarcity of traditional

energy carriers. In recent years, thermal insulation
paints based on hollow ceramics, glass and polymer
microspheres have attracted a lot of attention [1-3].
MATERIALS AND METHODS
The Youth Center for Innovative Technologies of the
Fergana Polytechnic Institute is conducting research to
improve the method of determining the thermal
conductivity of heat-insulating coatings. This paint is
used for thermal insulation, waterproofing, corrosion
protection and construction of facades of residential
and industrial buildings, internal heat retention and
protection, heating and engineering networks, process
pipes, thermal energy and capacity equipment
designed for constructions. The paint is made on the
basis of acrylic binders and hollow microspheres in the
form of whole fillers and other components [4-9]. The
mechanism of operation of thermal insulators with
hollow microspheres, which are part of the
composition, is radically different from the mechanism
of operation of "classic" heaters. Due to its unique
properties, the material has a significant energy-saving
result even at a thickness of 1 mm.
Picture 1. Results from the experiment
Our paint is flexible and has a high viscosity at low and
high temperatures. The paint does not contain
residues of the base material and does not form cracks
or chemical changes during its long service life (up to
15 years).
In addition to its heat-insulating properties, which
include water-resistant (impermeable) additives,
waterproofing also has anti-corrosion properties. The
components make the coating waterproof, flexible,
and at the same time resistant to UV, temperature
drops, moisture and external factors [10-13].
Once applied, the coating reacts with air to form a
durable, polymer coating, which provides excellent
thermal insulation properties that reduce heat loss.
The drying layer of one coating forms a film with a
thickness of 0.1 to 0.5 mm [14-19].The paint has a high
adhesion (glass (glass) adheres to concrete, brick,
cement-sand plaster, metal, plastic, wood and other
materials), prevents corrosion and condensation on
cold surfaces, mechanical and atmospheric does not
require additional protection from impact. Vacuum

suspended components in liquid synthetic rubber,
acrylic polymers and inorganic pigments. It resembles
a light gray suspension and forms an elastic ultra-thin
coating after drying. The combination of such
components has allowed creating a unique material
with flexibility, lightness, elasticity and the ability to
perfectly adhere to surfaces of any shape and almost
any chemical composition.
The paint has the following advantages:
Easy to apply (can be done by spraying with a
brush, roller and compressor);
Small size, compactness;
Environmentally friendly;
Does not contain harmful substances;
Good resistance to both alkalis and acids;
Fire resistant;
Areas of application
Residential and industrial buildings (external and
internal insulation);
Easy-to-install structures;
Metal structures (garages, containers,);
Heating mains, pipes, ventilation ducts;
Shut-off valves (valves and valves);
Industrial containers;
Car showrooms;
Non-combustible fireproof material. There are two
other types of resistance to liquid insulation:
temperature and humidity and resistance to ultraviolet
radiation. The composition of liquid thermal insulation
contains only environmentally friendly components,
which allows it to be used indoors and outdoors, in
children's institutions, public catering establishments,
etc., without restrictions on their functionality.
Easy to apply even in difficult areas. There are several
ways to apply liquid thermal insulation to the surface
of your choice. You just have to choose the one that
suits you best. You can use a variety of tools: brushes,
rollers, etc.
If your surface is concrete, use a brush to remove dust,
mold, and oil;
Metal surfaces should also be cleaned and
degreased. If there are rust stains on the metal, it
is recommended to treat them with a phosphating
compound.
Before applying the insulation, the wood should be
primed with primer and biocides.
If you are reworking a brick surface, you must first
prime it and then plaster it.
Thermal insulation coating is applied to metal,
concrete, brick, wood, plastic and many other surfaces.
The surface is pre-cleaned, primed if necessary, diluted
with water of the same composition (not more than
5%) or as a primer can be used as a primer of any acrylic
paint, liquid glass mixture.
Do not push the mixture on a damp, icy surface. The
mixture is laid in several layers. The number of layers is
determined by the tasks, depending on the objectives.
The layers can be applied several times with drying
intervals. The final thickness of the finished coating is
selected depending on the heat carrier temperature
and the desired surface temperature.
CONCLUSION
The coating is easily (laid) on the surface of any
geometric shape using a brush, spatula, roller or
sprayer. The coating does not emit harmful
compounds into the atmosphere. It is recommended
to use a normal respirator when working indoors, and
no respirator is required when working outdoors or in
a ventilated room. Average consumption for obtaining
