Problems solved by technology

[0004] (1) Due to the limitation of electrode structure and connection shape, it is difficult to realize the miniaturization, thinning and specialization of the heater
[0005] (2) The production process of electrode wires, especially high-temperature electrodes, is complicated, the production cycle is long, and the production cost is high
[0006] (3) The manufacturing process of the heating plate is complicated, which makes the degree of freedom of circuit design small and the degree of automation low
[0007] (4) Solder joints are easy to fall off when heated, the surface is easy to oxidize, and the service life is short
[0008] (5) The riveting part is easy to catch fire, loosen and crack, resulting in unsafe use
[0009] (6) The circuit design of the heater can only be a series structure, the limitation of the circuit design is large, and the failure rate is high

Embodiment Construction

[0092] The invention provides an electrothermal high-temperature-resistant organic electrode slurry especially suitable for plate heaters, which is mainly composed of an organic binder phase, a functional phase, a functional auxiliary phase and other functional phases. The formulation mechanism is explained as follows:

[0093] The organic binder phase is the main body of the system formula, which is mainly a blend of epoxy modified high molecular polymer, boron flame retardant and temperature resistant high molecular polymer and silicon modified high polymer organic body. It mainly provides the slurry system with excellent adhesion to the printing substrate, and excellent geometric deformation consistency with the printing substrate; provides a stable geometric structure and surface hardness for the cured film, so that the cured film has excellent temperature resistance, and Good flame retardancy and thermal oxygen aging resistance; provide suitable viscosity, leveling perfor...

Abstract

The invention relates to an electrothermal organic electrode slurry for a heater. The slurry comprises the following main components in percentage by weight: 5-30% of epoxy modified high polymer, 2-6% of flame-retardant temperature-resistant high polymer, 3-6% of latent curing agent, 1-2% of latent curing promoter, 5-10% of silicon modified high polymer, 50-70% of superfine metal powder conductive filler, 1-3% of antioxidant assistant, 0-5% of base metal alloy powder conductive filler and a small amount of functional auxiliary phase. The invention solves the problem that the ordinary slurry is difficult to realize thin type, light type or special type, has the characteristics of low-temperature curing and high-temperature use, ensures direct printing or spraying and satisfies the technical development requirements of small type, thin type, light type (shape and application) and special type of the electric heater.

Description

technical field [0001] The invention relates to an organic electrothermal conductor material, in particular to an electrothermal organic electrode slurry for a heater. Background technique [0002] The heating method of ordinary heaters still uses the traditional nickel / chromium alloy resistance wire or film as the heating material so far. With the improvement of the performance, structure, safety, environmental protection and other requirements of heaters at home and abroad, the demand for plate heaters continues to increase, especially in the high-tech field, which puts forward higher requirements for the thinning and special performance of heaters . The traditional nickel / chromium alloy resistance wire or film as the heating mode and heating material can no longer meet the requirements of technological development. [0003] The resistance wire heaters that have been commercialized at present are generally electrode wires riveted or welded on the substrate. The electrode...
