Problems solved by technology

[0003] The main body of the axle is a metal part. Generally, a metal protective layer is provided on the surface of the metal part. However, the existing metal protective layer often has defects of poor hardness and easy scratches, which makes it difficult to guarantee the service life of the axle.

preparation example Construction

[0012] The invention provides a kind of preparation method of high-hardness axle coating, comprising:

[0013] 1) Melt silicon dioxide, aluminum dioxide, iron dioxide, magnesium oxide, antimony trioxide, potassium oxide, europium oxide, and cerium oxide, then cool and crush to obtain crushed particles;

[0014] 2) Ball mill crushed particles, bentonite, spinel, polyvinyl alcohol and water to obtain high hardness axle paint.

[0015] In step 1) of the present invention, the amount of each material can be selected within a wide range, but in order to further improve the hardness of the prepared coating after film formation, preferably, in step 1), silicon dioxide, di The weight ratio of aluminum oxide, iron dioxide, magnesium oxide, antimony trioxide, potassium oxide, europium oxide, and cerium oxide is 50:10-15:2-4:1-3:4-6:2-5:1.2 -1.8: 2.2-2.6.

[0016] In step 1) of the present invention, the step of melting can be selected in a wide range, but in order to further improve t...

Embodiment 1

[0025] 1) Mix silicon dioxide, aluminum dioxide, iron dioxide, magnesium oxide, antimony trioxide, potassium oxide, europium oxide, and cerium oxide in a weight ratio of 50:13:3:2:5:3:1.6:2.4 Melt (from 825°C to 1080°C at a rate of 2°C / min and hold for 50 minutes, then raise the temperature to 1320°C at a rate of 3.3°C / min and hold for 50 minutes), then naturally cool and crush to obtain crushed particles (average particle size 5mm);

[0026] 2) Ball mill the pulverized particles, bentonite, spinel, polyvinyl alcohol and water according to the weight ratio of 70:6:2.5:28:45 to obtain high-hardness axle coating A1 (the particle size of the solid particles is not greater than 180 mesh) .

Embodiment 2

[0028] 1) Mix silicon dioxide, aluminum dioxide, iron dioxide, magnesium oxide, antimony trioxide, potassium oxide, europium oxide, and cerium oxide in a weight ratio of 50:10:2:1:4:2:1.2:2.2 Melt (from 820°C at a rate of 1.5°C / min to 1050°C and hold for 40 minutes, then at a rate of 3°C / min to 1300°C and hold for 40 minutes), then naturally cool and crush to obtain crushed particles (average particle size is 4mm);

[0029] 2) Ball mill the pulverized particles, bentonite, spinel, polyvinyl alcohol and water according to the weight ratio of 70:4:2:25:35 to obtain high hardness axle coating A2 (the particle size of the solid particles is not greater than 180 mesh) .

Abstract

The invention discloses a high-hardness vehicle axle paint and a preparation method thereof. The preparation method of the paint and preparation method thereof comprises: 1, carrying out melting on silicon dioxide, aluminium dioxide, ferrum dioxide, magnesium oxide, antimony trioxide, potassium oxide, europium oxide and cerium oxide, and then cooling and smashing to obtain smashed particles; 2, carrying out ball milling on the smashed particles, bentonite, spinel, polyvinyl alcohol and water so as to obtain the high-hardness vehicle axle paint. The high-hardness vehicle axle paint can form a high-hardness coating on the surface of a metal main body of a vehicle axle, and meanwhile, the preparation method has the advantages of simple process and easiness for obtaining the raw materials.

Description

technical field [0001] The invention relates to vehicle axles, in particular to a high-hardness vehicle axle coating and a preparation method thereof. Background technique [0002] The axle, also known as the axle, is connected to the frame (or load-bearing body) through the suspension, and the car wheels are installed at both ends. The axle can be integral, like a huge barbell, and the two ends support the body through the suspension system, so the integral axle usually cooperates with the non-independent suspension; the axle can also be disconnected, like two Umbrellas are inserted on both sides of the vehicle body, and then each supports the vehicle body through the suspension system, so the disconnected axle is used with the independent suspension. [0003] The main body of the axle is a metal part, and a metal protective layer is generally arranged on the surface of the metal part. However, the existing metal protective layer often has the defects of poor hardness and ...
