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
The present invention relates to auto parts machinery field, high temperature insulating material and preparation method for especially a kind of electronic heater.
Background technology
The device energy autocontrol valve that adjusts the temperature electronically changes the flow of liquid automatically according to the operating mode of the variations in temperature of liquid and engine, make engine reach optimum working state, be emerging energy-conserving and environment-protective in the world in recent years, a kind of high-end product that improves engine performance, traditional mechanical type thermosistor cannot be realized.The core of device autocontrol valve of adjusting the temperature electronically is that heater part is electronic heater, owing to being subject to the restrictions such as environment for use, production technology, the electronic heater of small size is still blank at home, external product quality also fluctuates always, and subject matter is that the life-span is short, warm-up time is long, sensitivity is low.
Summary of the invention
In order to solve the technical problem that the above-mentioned life-span is short, warm-up time is long, sensitivity is low, the invention provides a kind of electronic heater high temperature insulating material and preparation method.
Technical scheme of the present invention is as follows:
A kind of electronic heater high temperature insulating material, is prepared from by following raw materials according:
Composition weight proportion
Aluminium hydroxide 10-20 part
Phosphatase 11 5-25 part
Aluminium oxide 45-55 part
Alcohol 10-22 part
As preferably, composed as follows:
15 parts, aluminium hydroxide
21 parts of phosphoric acid
50 parts, aluminium oxide
14 parts of alcohol
The preparation method of high temperature insulating material for above-mentioned a kind of electronic heater, a, the oxidation of aluminium oxide ball milling add above-mentioned aluminium oxide by weight percentage in ball mill, ball milling 40 ~ 50h, is fully oxidized aluminium oxide, take out standby, drum's speed of rotation 120r/min; B and material stir, and will in the aluminium oxide after oxidation, add by the aluminium hydroxide of above-mentioned weight percent and put into together mixer, and the dry 3-5min that stirs, then adds phosphoric acid, alcohol to stir 40-50min and take out by weight percentage; C, heat-preservation fermentation, join closed container heat-preservation fermentation 15 hours at 40-45 ℃ of temperature by the material being stirred.
Use technical scheme of the present invention, good fluidity, can be filled in the electronic heater heat-generating pipe gap in about internal diameter 3mm, length 100mm, make the each parts of electronic heater be solidified into one, can vibration resistance; High temperature insulating material high temperature resistant, that use both at home and abroad at present, heatproof is no more than 500 ℃, and high temperature insulating material heatproof of the present invention can reach 1500 ℃; Heat conduction is fast, the response time is short, and being used in the same kind of products at abroad response time on heater is 12S, and our company's product response time is less than 6S, has greatly improved the sensitivity of heater, and life of product can improve more than 2 times.
