Problems solved by technology

Heating cable floor heating generally uses heating cables as the heat source and is buried under the floor or in the floor. This system has disadvantages such as high production cost, inconvenient maintenance, and uneven heat transfer.
The electric heating film floor heating heats up by placing the electric heating film under the floor or in the floor. The conductive ink, metal, graphene and other current-carrying strips are processed and hot-pressed between the insulating polyester films. If heated for a long time, they will shrink. leading to a decrease in heating efficiency
Carbon fiber floor heating is flat heating, its thickness is mostly about 20mm, and the panel is glass magnesium board, which is easy to bulge after being eroded by moisture and water. When paving, a gap of 8-15cm should be left between each piece to install the power wire, which is easy Damage caused by uneven force on the floor

Abstract

The invention discloses an electrothermal floor heating insulation board, which comprises a surface material and a substrate. The surface material is arranged on upper and lower surfaces of the substrate, and the surface material on the upper surface of the substrate is an electrothermal film. The substrate is formed by a reaction among inorganic particles, a solid flame retardant and a rigid polyurethane foam foaming material, and comprises the following raw materials (by weight): 34-83 parts of inorganic particles, 2-17 parts of a solid flame retardant, and 15-49 parts of the rigid polyurethane foam foaming material. Thermal conductivity coefficient of the substrate is 24.0-35.0 mW / (m.K), and the combustion performance grade is not lower than the B1 grade in GB8624-2012 ''Classificationof Combustion Performance of Building Materials and Products''. According to the electrothermal floor heating insulation board, water absorption per volume is less than or equal to 3.0%, dimensional stability (30 DEG C, 48 h) is less than or equal to 1.0%, compression strength is greater than or equal to 0.15 MPa, and the product has characteristics of low temperature radiation, water resistance and heat preservation and good high temperature dimensional stability, is capable of bearing, is integrated as a whole and is easy to install and maintain.

Description

technical field [0001] The invention belongs to the technical field of floor heating, and in particular relates to an electric floor heating insulation board and a preparation method thereof. Background technique [0002] Ground radiation heating is mainly divided into water floor heating and electric floor heating according to different heating methods. Compared with water floor heating, electric floor heating mainly has the advantages of comfort, energy saving, environmental protection, flexibility, and no maintenance, so it has gradually entered every household. There are many types of electric floor heating, commonly used are heating cable floor heating, electric heating film floor heating and carbon fiber floor heating. Heating cable floor heating generally uses heating cables as the heat source and is buried under the floor or in the floor. This system has disadvantages such as high production cost, inconvenient maintenance, and uneven heat transfer. The electric hea...
