Environment-friendly energy-saving electrothermal film material

Abstract

The invention discloses an environment-friendly energy-saving electrothermal film material. The environment-friendly energy-saving electrothermal film material is characterized by comprising the following substances in parts by weight: 30-40 parts of EVA (ethylene and vinyl acetate) ester, 10-30 parts of nano organic montmorillonite, 10-36 parts of a filler, 1-9 parts of a film forming additive, 2-8 parts of a cosolvent, 2-3 parts of a wetting agent, 3-4 parts of a dispersing agent, 10-32 parts of polyacrylate, 15-36 parts of a solid stone esters, 26-31 parts of stearic acid, 15-28 parts of stearate, 10-15 parts of stearamide, 2-3 parts of an inorganic thickening agent, 1-4 parts of a toughening agent, 3-8 parts of a flame retardant, 3-8 parts of pulverized fuel ash, 2-9 parts of hemihydrate gypsum and 1-3 parts of cellulose fiber. The environmentally-friendly energy-saving electrothermal film material disclosed by the invention has the advantages of low raw material cost, simple preparation process, high thermal efficiency, high temperature increase speed, energy saving, environment friendliness, wide application range, stable physical and chemical properties, good thermal stability, acid, alkali and wear resistance and long service life.

Description

technical field [0001] The invention relates to a green energy-saving electrothermal film material. Background technique [0002] Nano electrothermal film heating element belongs to planar heating, its electrothermal efficiency is about 30% higher than that of ordinary resistance heating element, the heating speed is fast, and it has the function of far infrared radiation heating, which has the effect of physiotherapy; but there are three common problems in other invented electrothermal film : 1. The combination between the electrothermal film and the base material is not very good, and it is easy to cause defilming phenomenon if it is used for a long time; 2. The production process of the electrothermal film is complicated or the use of expensive raw materials is not cost-effective; 3. The vast majority in the market Most electrothermal films only reach the micron level, and their operating temperature and operating voltage are more restricted, and their application range i...

[0002] Nano electrothermal film heating element belongs to planar heating, its electrothermal efficiency is about 30% higher than that of ordinary resistance heating element, the heating speed is fast, and it has the function of far infrared radiation heating, which has the effect of physiotherapy; but there are three common problems in other invented electrothermal film : 1. The combination between the electrothermal film and the base material is not very good, and it is easy to cause defilming phenomenon if it is used for a long time; 2. The production process of the electrothermal film is complicated or the use of expensive raw materials is not cost-effective; 3. The vast majority in the market Most electrothermal films only reach the micron level, and their operating temperature and operating voltage are more restricted, and their application range is narrow

The defects in these three aspects lead to certain difficulties in the performance and promotion of the electric heating film
