Abstract

The invention provides composite electric heating paint for a flexible base material as well as a preparation method and a use thereof. Organic or inorganic resin is used as a binder, and the composite material is added into various auxiliaries as conductive filler. The composite electric heating paint consists of the following components in parts by weight: 1-100 parts of composite conductive filler, 1-200 parts of a high molecular resin binder, 1-50 parts of auxiliaries and 100-300 parts of a solvent. The composite electric heating material can be quickly heated within 3-5 minutes, namely the heating rate is higher than the heating rate of the existing similar electric heating paint; the electric heating paint is suitable for being applied in a low-temperature heating field within 0-100 DEG C, is especially suitable for being applied to agricultural, military and industrial production as well as heating, warming and the like in daily life, and can be used for biological breeding, hatching electric-heating insulating chamber and the like in agriculture.

Description

technical field [0001] The invention relates to a coating, in particular to a composite electrothermal coating for a flexible substrate, a preparation method and an application thereof. Background technique [0002] Electrothermal coating is a new type of functional coating with excellent electrothermal properties. It can be applied to the surface of the object to be heated or heated on any surface like paint. Because it can be directly applied to the surface of the substrate, it has extremely High thermal efficiency. With the continuous development of the science and technology industry, the performance requirements for functional coatings are constantly improving, and as a kind of functional coatings, the research and development of electrothermal coatings is constantly deepening, and the requirements for the electrothermal performance of electrothermal coatings are also higher. At the same time Many properties that are closely related to the application environment are a...
