Embodiment 1

[0015] A rust-proof crawler chassis is coated with a protective layer on the crawler chassis. The coating method is as follows:

[0016] (1) Sandblasting on the outer surface of the crawler chassis;

[0017] (2) Weigh the raw materials: Weigh 22 parts by weight of epoxy resin, 4.4 parts of isocyanate, 2 parts of xylene, 5 parts of silica, 10 parts of ethanol, 0.05 parts of defoamer, 1 part of photoinitiator ;

[0018] (3) Stir the raw materials evenly at a temperature of 40-55°C and coat them on the outer surface of the crawler chassis, and then dry.

[0019] Further, the weight ratio of the epoxy resin and isocyanate is 5:1.

[0020] Further, the drying temperature is 100-130°C, and the drying time is 10-24h.

Embodiment 2

[0022] A rust-proof crawler chassis is coated with a protective layer on the crawler chassis. The coating method is as follows:

[0023] (1) Sandblasting on the outer surface of the crawler chassis;

[0024] (2) Weigh the raw materials: weigh 15 parts by weight of epoxy resin, 3 parts of isocyanate, 0.5 parts of xylene, 2 parts of silica, 8 parts of ethanol, 0.03 parts of defoamer, 0.8 parts of photoinitiator ;

[0025] (3) Stir the raw materials evenly at a temperature of 40-55°C and coat them on the outer surface of the crawler chassis, and then dry.

[0026] Further, the weight ratio of the epoxy resin and isocyanate is 5:1.

[0027] Further, the drying temperature is 100-130°C, and the drying time is 10-24h.

Embodiment 3

[0029] A rust-proof crawler chassis is coated with a protective layer on the crawler chassis. The coating method is as follows:

[0030] (1) Sandblasting on the outer surface of the crawler chassis;

[0031] (2) Weigh the raw materials: weigh 28 parts by weight of epoxy resin, 5.6 parts of isocyanate, 3.2 parts of xylene, 6 parts of silica, 15 parts of ethanol, 0.08 parts of defoamer, 1.2 parts of photoinitiator ;

[0032] (3) Stir the raw materials evenly at a temperature of 40-55°C and coat them on the outer surface of the crawler chassis, and then dry.

[0033] Further, the weight ratio of the epoxy resin and isocyanate is 5:1.

[0034] Further, the drying temperature is 100-130°C, and the drying time is 10-24h.

Abstract

The invention provides a rust-proof crawler chassis. The crawler chassis is coated with a protective layer. A coating method comprises the following steps of 1, conducting sandblasting treatment on the outer surface of the crawler chassis; 2, weighing raw materials, wherein the raw materials include, by weight, 15-28 parts of epoxy resin, 3-5.6 parts of isocyanate, 0.5-3.2 parts of dimethylbenzene, 2-6 parts of silicon dioxide, 8-15 parts of ethanol, 0.03-0.08 part of defoaming agent and 0.8-1.2 parts of photoinitiator; 3, evenly stirring the raw materials at 40-55 DEG C and then coating the outer surface of the crawler chassis with the mixed raw materials, and conducting drying. Rust is effectively prevented, and the service life is prolonged.

Description

Technical field [0001] The invention relates to a crawler chassis, in particular to a rust-proof crawler chassis. Background technique [0002] The tracked chassis is a device used to support the various components of the vehicle chassis and ensure the normal running of the vehicle. Tracked chassis has the advantages of large traction, low grounding ratio, good stability, and strong climbing ability. Therefore, it is widely used in construction machinery, road construction machinery and agricultural machinery. In the field of agricultural machinery, it is widely used in agricultural institutions such as rotary tillers and harvesters because it can adapt to farming and silt-laden land. [0003] The existing tracked chassis is easy to rust, which affects the normal use of the vehicle. Summary of the invention [0004] In view of the above problems, the present invention provides a rust-proof crawler chassis, which effectively prevents rust and improves the service life. [0005] The ...
