Embodiment 1

[0074] According to Embodiment 1 of the present invention, 100 parts of the heating paste composition further includes 0.5-5 parts by weight of a silane coupling agent.

[0075] The silane-containing coupling agent has the function of an adhesion promoter to enhance the bonding force between resins during the formulation of the heating paste composition. The silane-containing coupling agent may be epoxy-containing silane or mercapto-containing silane. Examples of such silane-containing coupling agents include 2-(3,4-epoxycyclohexyl)-ethyltrimethoxysilane, 3-glycidyltrimethoxysilane, 3-glycidol Oxypropyltriethoxysilane, 3-glycidoxypropyltriethoxysilane; N-2 (aminoethyl) 3-aminopropylmethyldiethoxysilane, N -2(amino-ethyl)-3-aminopropyltriethoxysilane, 3-aminopropyltriethoxysilane, 3-aminopropyltriethoxysilane, 3-triethoxysilane Base-N-(1,2-dimethylbutylidene)propylamine, N-phenyl-3-aminopropyltriethoxysilane; mercapto-containing 3-mercaptopropylmethyldiethoxy 3-mercaptopropy...

experiment example

[0082] (1) Prepare Examples and Comparative Examples

[0083] Examples (three types) and comparative examples (three types) were prepared as follows [Table 1]. The composition ratio indicated in [Table 1] indicates that it is described in terms of weight percent (%).

[0084] [Table 1]

[0085]

[0086]

[0087] In the case of the examples, CNT particles and CNP particles (Examples 1 to 3) have the composition according to [Table 1] After adding BKY dispersant to the carbitol acetate solvent, dispersant A was prepared by ultrasonic treatment for 60 minutes . Afterwards, the organic solvent was added to the carbitol acetate and then mechanically stirred to prepare a masterbatch. In the next step, after the first round of mixing of the dispersant A and the masterbatch is carried out by mechanical stirring, the heating paste composition is prepared after the second round of mixing in the process of three-roll rolling.

[0088] In the case of the comparative example, a...

Abstract

A heating device for an electric vehicle, according to an embodiment of the present invention, comprises: a water pump which is for circulating supplied water; a heating resistor which has one or moresurface type heating elements formed by means of a heating paste composition and is for heating the circulated water; a water temperature sensor which is for measuring the temperature of the hot water heated by means of the heating resistor; and a control unit which is for adjusting the heating resistor such that the measured temperature measured by means of the water temperature sensor satisfiesa set temperature value, wherein the heating paste composition comprises, on the basis of 100 parts by weight of the total heating paste composition, 3-6 wt % of carbon nanotube particles, 0.5-30 wt% of carbon nanoparticles, 10-30 wt % of a mixed binder, 29-83 wt % of an organic solvent, and 0.5-5 wt % of a dispersant, wherein the mixed binder has epoxy acrylate, polyvinyl acetal and phenolic resin mixed therein or has hexamethylene diisocyanate, polyvinyl acetal and phenolic resin mixed therein.

Description

technical field [0001] The invention belongs to an electric vehicle heating device and a control method thereof. Background technique [0002] Generally speaking, in order to realize heating in the car, a heating device is often installed on the car. In addition to the heat produced by the engine, this heating device can also use other heat sources other than the engine. According to different heat sources, the heating device can be divided into a hot water type using engine cooling water and a type using an independent burner without using the waste heat of the engine. [0003] Among them, the hot water heating device uses the high temperature generated by the engine to heat the cooling water and then partially introduces it into the heater, and at the same time heats the air flowing around the heater and blows it into the car through the blower to achieve heating. [0004] Figure 4 It simply shows the composition of the hot water heating device that uses the heat genera...
