Problems solved by technology

However, since the floor, especially the solid wood composite floor, is made of multiple pieces of wood boards bonded by adhesives, under long-term heating conditions, the adhesive force of the adhesives is likely to decrease, and the boards are degummed and warped.
On the other hand, due to the poor performance of the existing adhesives and waterproofing agents, the waterproof effect of the existing electric heating floor is not satisfactory, and the waterproof performance is a very important indicator for the electric heating floor. Water is extremely easy to cause safety accidents

Abstract

The invention discloses a technology for preparing an electric-heat solid-wood composite floor with a built-in heating layer and a product thereof. The technology sequentially includes the following steps that a, a composite base material is coated with melamine-modified urea-formaldehyde resin adhesive, standing is carried out for 5 min, then carbon fiber paper is pasted to the surface of the composite base material, and copper electrodes composed of copper sheets and copper nails are installed; b, the carbon fiber paper is coated with melamine-modified urea-formaldehyde resin adhesive, and after standing is carried out for 10 min, the carbon fiber paper is covered with a surface decoration veneer; c, cold pressing is carried out for 10 min at the pressure of 0.6 MPa, and hot pressing is carried out for 8 min at the pressure of 1.2 MPa after cold pressing; d, standing is carried out for 5-7 days, forming and grooving are carried out to prepare a blank plate, the ends and the side faces of the blank plate are coated with waterproof agents, the surface of the blank plate is coated with paint for decoration, and the finished product is obtained.

Description

technical field [0001] The invention relates to a wooden floor and a production method thereof, in particular to a preparation process of an electric heating solid wood composite floor with a built-in heating layer and a product thereof. Background technique [0002] As we all know, flooring has gradually become a necessity for home decoration and has entered most families due to its very practical functions such as moisture insulation, cold resistance, and comfort. With the continuous improvement of people's living standards, the use function of the floor is also continuously improved. In order to solve the problem of heating in winter, more and more families use electric heating floors that can generate heat for heating. However, since the floor, especially the solid wood composite floor, is made of multiple wood boards bonded by adhesives, in a long-term heating state, the adhesive force of the adhesives is likely to decrease, and the problem of degumming and warping of ...
