Abstract

The invention discloses a preparation method of a heating chip with fused nanometer carbon fibers and wood fibers. The carbon fibers are sufficiently separated in water through aqueous dispersant. Bymeans of an acid-base balance neutralizing characteristic, a carbon fiber material and a vegetable fiber material are sufficiently fused, and filling of vegetable fiber pores by nanometer-grade graphite conductive particles is realized. The preparation method is characterized in that a specific rule is formed in a fiber material manufacturing process through a current flow direction function, so that resistance uniformity of the heating chip is greatly improved and higher stability is realized.

Description

technical field [0001] The invention relates to the technical field of heating floors, in particular to a method for preparing a heating chip in which carbon nanofibers and wood fibers are fused. Background technique [0002] The heating floor, as the name suggests, is a floor that can generate heat, a floor that can provide heat to the house. More than ten years ago, scientists from Germany, the United States, Japan and other countries took thermal energy efficient technology as a research topic, seeking to invent a high-efficiency, energy-saving, environmentally friendly, and low-carbon thermal energy that can be used in aerospace, technology, and civil fields. Efficient conversion of materials. The indoor ground heating material based on the floor, or it is a functional floor, its appearance is the same as that of an ordinary floor, except that a high-tech heating layer is built in the middle of the floor. Its distinctive feature is that the floor It can continuously ge...
