Problems solved by technology

Because there is a large temperature difference between the temperature of the blower shell of the automobile air conditioner during the working process and the temperature after it stops working, under such a large temperature difference, the blower shell of the automobile air conditioner will often be deformed, which will affect the fan. The working performance of the leaf, and its mechanical properties will be greatly reduced

preparation example Construction

[0013] The invention provides a method for preparing an automobile air-conditioning blower casing, the preparation method comprising:

[0014] 1) Soak montmorillonite and the compound of the structure shown in formula (I) in hydrochloric acid solution and carry out ultrasonic vibration, then filter to get the filter residue;

[0015] 2) PC, PPA, PEG, PVP, melamine cyanurate, ethoxylated (tallow alkyl) amine, dimethyl tin, rare earth oxide, sodium metavanadate, isopimaric acid, cellulose triacetate and filter residue Melting, and then solidified to form the blower shell of the automobile air conditioner,

[0016]

[0017] In the present invention, the specific conditions of ultrasonic vibration can be selected in a wide range, but in order to make montmorillonite and the compound of the structure shown in formula (I) can be fully activated and fully compatible, preferably, in step 1 ), in step 1), the ultrasonic oscillation at least satisfies the following conditions: the o...

preparation example 1

[0026] The preparation of structural compounds as shown in formula (I): according to the method of embodiment 1 and 2 recorded in the patent that the notification number is CN104418915A, it is obtained,

[0027]

Embodiment 1

[0029] 1) Soak the montmorillonite and the compound of the structure shown in formula (I) in a hydrochloric acid solution with a pH of 5 according to the weight ratio of 100:10 (the weight ratio of the montmorillonite to the hydrochloric acid solution is 100:700) and perform ultrasonic Oscillate for 50 minutes (oscillation temperature is 50°C, ultrasonic frequency is 30,000 Hz), then filter to get the filter residue;

[0030] 2) PC (weight average molecular weight is 10000), PPA (weight average molecular weight is 20000), PEG (weight average molecular weight is 5000), PVP (weight average molecular weight is 6000), melamine sodium cyanurate, ethoxylated (tallow alkyl ) amine, dimethyl tin, europium oxide, sodium metavanadate, isopimaric acid, cellulose triacetate and filter residue according to 100:28:6:4:1.7:11:5:0.8:6:4:12:10 The weight ratio is mixed and melted at 210°C for 2.5h, then the mixture is passed through the extrusion die (the die temperature is 188°C, the pressure...

Abstract

The invention discloses an automotive air conditioning blower casing and a preparation method thereof. The preparation method comprises steps as follows: montmorillonite and a compound with a structure represented as a formula (I) are soaked in a hydrochloric acid solution and subjected to ultrasonic oscillation, a mixture is filtered, and filter residues are taken; 2), PC (polycarbonate), PPA (polyphthalamide), PEG (polyethylene glycol), PVP (polyvinylpyrrolidone), melamine cyanurate, POE (15) tallow amine, dimethyltin dichloride, rare earth oxide, sodium metavanadate, isopimaric acid, cellulose triacetate and the filter residues are fused and subjected to curing forming, and the automotive air conditioning blower casing is prepared. The automotive air conditioning blower casing has excellent weather resistance and mechanical properties, meanwhile, the preparation method has simple steps, and raw materials are easily available.

Description

technical field [0001] The invention relates to automobile air-conditioning components, in particular to an automobile air-conditioning blast shell and a preparation method thereof. Background technique [0002] The car air conditioner blower shell is an important part of the car air conditioner blower. The car air conditioner blower mainly plays the role of blowing hot or cold air to play the role of gas circulation, and the car air conditioner blower shell plays the role of protecting the car air conditioner. The internal parts of the blower also play the role of forming the air duct. [0003] At present, the blower shell of the automobile air conditioner is generally made of polymer materials. Because there is a large temperature difference between the temperature of the blower shell of the automobile air conditioner during the working process and the temperature after it stops working, under such a large temperature difference, the blower shell of the automobile air con...
