Embodiment 1

[0025] A method for preparing a high-temperature insulating material for an electronic heater as claimed in claim 1, the preparation is as follows: take 48 parts of alumina and add it to a ball mill, take it out after ball milling for 40 to 50 hours at a ball mill speed of 120r / min, and add At the same time, add 12 parts of aluminum hydroxide to the mixer, dry stir for 3-5 minutes, then add 20 parts of phosphoric acid and 20 parts of alcohol and stir for 40-50 minutes. Performance index: Insulation resistance 1800MΩ, fluidity is very good.

Embodiment 2

[0027] Take 52 parts of aluminum oxide and put it into the ball mill, mill it for 40~50 hours under the condition of ball mill speed 120r / min, take it out and add it to the mixer, add 15 parts of aluminum hydroxide to the mixer at the same time, add 18 parts of phosphoric acid and 15 parts of alcohol after dry stirring for 3~5 minutes Stir each portion for 40~50min. Performance indicators: insulation resistance 2000MΩ, good fluidity.

[0028] The performance data of a kind of high-temperature insulation material for electronic heaters prepared by the present invention is as follows:

Abstract

The invention relates to the field of automobile parts, in particular to a high-temperature insulation material for an electronic heater and a preparation method. The high-temperature insulation material for the electronic heater is prepared from the following raw materials: 10-20 parts of aluminum hydroxide, 15-25 parts of phosphoric acid, 45-55 parts of aluminum oxide and 10-22 parts of alcohol. The high-temperature insulation material has the advantages of being good in fluidity, capable of being filled in gaps between electronic heater heating tubes with the internal diameter of 3 millimeters or so and the length of 100 millimeters below to enable parts of the electronic heater to be solidified into a whole, and also capable of resisting vibration and high temperature; at present, high-temperature insulation materials used home and abroad can not resist the temperature higher than 500 DEG C. The high-temperature insulation material can resist the temperature up to 1500 DEG C, and is fast in heat conduction and short in response time; the response time of a foreign similar material for the electronic heater is 12 seconds, and the response time of the product in our company is smaller than six seconds. Consequently, the sensitivity of the electronic heater is greatly improved, and the service life of the product can be prolonged by more than twice.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a high-temperature insulating material for an electronic heater and a preparation method thereof. Background technique [0002] The electronic thermostat can automatically control the valve to automatically change the flow of the liquid according to the temperature change of the liquid and the working condition of the engine, so that the engine can reach the best working condition. High-end products are beyond the reach of traditional mechanical thermostats. The core of the electronic thermostat automatic control valve is the heating element, that is, the electronic heater. Due to the limitations of the use environment and production process, the small-sized electronic heater is still blank in China, and the quality of foreign products has also been stagnant. The main The problem is short life, long warm-up time, and low sensitivity. Contents of the invention [0003] In order to so...
