Three-layer solid wood composite electric heating floor and manufacturing method thereof

Abstract

The invention discloses a three-layer solid wood composite electric heating floor and a manufacturing method thereof. The three-layer solid wood composite electric heating floor comprises a decoration wood veneer, an upper insulation layer, an electric heating chip, a lower insulation layer and a three-layer solid wood base material layer. The three-layer solid wood base material layer is formed by laminating an upper wood veneer, a lower wood veneer and a solid wood batten base material layer clamped between the upper wood veneer and the lower wood veneer. The decoration wood veneer, the upper insulation layer, the electric heating chip, the lower insulation layer and the three-layer solid wood base material layer are sequentially overlapped and laid from top to bottom and laminated into the complete floor. The lower surface of the decoration wood veneer is coated with insulation resin glue to form the upper insulation layer and is attached to the upper surface of the electric heating chip. The upper surface of the three-layer solid wood base material layer is coated with insulation resin glue to form the lower insulation layer and is attached to the lower surface of the electric heating chip. The electric heating chip is formed by coating the surface of a copper strip used as a power plug with conductive hot melt glue and laying the copper strip on the surface of carbon fiber electric heating non-woven paper. According to the three-layer solid wood composite electric heating floor, the amount of adopted glue is small, the deformation degree is low, and the floor is more environmentally friendly. The electric heating chip and the copper strip are connected firmly, safety is good, and the service life is long.

Description

technical field [0001] The invention relates to a three-layer solid wood composite electric heating floor and a preparation method thereof. Background technique [0002] In the prior art, the base material of the multi-layer solid wood composite heating floor is made of multiple veneers coated with glue and then overlapped and pressed to form a multi-layer solid wood composite base material. After gluing, press to form a substrate layer; 2) Sand the surface of the substrate board and then punch holes in the power supply part; 3) Coat the surface of the large substrate board with resin glue and then spread conductive paper; 4) No The copper tape with any technical measures is directly placed on the conductive paper; 5) The lower surface of the decorative layer is glued and laid on the conductive paper, 6) After being pressed by a hot press, it is cured, sanded and thickened before cutting the floor Specifications, 7) Grooving and painting treatment. [0003] There are follo...

AI Technical Summary

Problems solved by technology

[0004] 1) Due to the use of more than 6 layers of large sheets of veneer on the base layer, the deformation of the floor is large, and the specifications of the heating floor are limited. It is only suitable for the production of smaller specifications such as: 910X127mm, with an area of ​​only 0,115 square meters; 2) Lamination of multi-layer veneer requires the use of a large amount of glue, which reduces the environmental performance of the product; 3) Due to the large amount of glue used, the coefficient of thermal expansion of the glue is greater than that of wood materials during heating, which increases the deformation of the floor; 4) Conductive paper and copper tape Direct laying without any technical treatment, resulting in poor contact, failure and short service life of power attenuation; 5) Due to the small size of the floor, a large number of power cords and connectors should be added correspondingly when laying, so more power cords and labor will be spent, and Bring more hidden dangers of failure
