Problems solved by technology

Concrete has many capillary structures and is very easy to absorb water. The outer surface of concrete PC beams is eroded by many factors such as acid rain, urban exhaust gas emissions, dust, oil, and weak acid substances, which will undoubtedly accelerate the carbonization speed of concrete PC beams. Guided driving, so that there are obvious friction and wear marks on the guiding parts of the concrete PC beam. If effective protection is not taken for the parts of the wear marks, its normal service life will be affected

Embodiment 1

[0039] Such as figure 1 Shown, the coating method of concrete PC beam antiskid wear-resistant coating, described coating method comprises the following steps:

[0040] S1, pretreating the concrete PC beam 2, so that the surface to be painted of the concrete PC beam 2 is dry and clean, free of dirt and oil, and the surface roughness meets the preset requirements;

[0041] S2, coating the primer 11 on the surface to be painted of the concrete PC beam 2;

[0042] S3, after the primer 11 is dry, apply the anti-slip and wear-resistant paint film 12 on the primer 11, and wait until the anti-skid and wear-resistant paint film 12 is dry.

[0043]The environmental conditions for coating the anti-slip and wear-resistant coating 1 of the present embodiment are: the air temperature is between 5°C and 35°C, and construction in rain, fog, snow, wind and dust is prohibited; the air humidity is less than 80%; the concrete PC The temperature of the base surface of the beam should be more tha...

Embodiment 2

[0060] Such as figure 1 As shown, in the concrete PC beam of this embodiment, the concrete PC beam 2 is coated with an anti-slip and wear-resistant coating 1, and the anti-slip and wear-resistant coating 1 is coated on the concrete PC by the method described in Example 1. The surface of beam 2.

[0061]The thickness of the anti-slip and wear-resistant coating of the present embodiment is tested to the thickness of the paint film coating on the PC beam walking surface by GB / T1764-1979 "Method for Determination of Paint Film Thickness"; testing equipment: TT220 type magnetic thickness gauge; quality standard, Detection value: The total thickness of the coating should be greater than 3mm.

[0062] The adhesion performance of the anti-slip and wear-resistant coating of the present embodiment is tested by the cross-hatch method according to GB / T5210-2006 / ISO 4624:2002 "Paint and Varnish Cross-hatch Adhesion Test"; quality standard, test value: coating Adhesion level 0.

Abstract

The invention relates to a coating method of an anti-slide wear-proof coating layer of a concrete PC beam and the concrete PC beam. The coating method comprises the following steps: (S1) preprocessing the concrete PC beam until a to-be-coated surface of the concrete PC beam is dry and neat and has no dirt and oil dirt and the surface roughness meets the preset requirements; (S2) coating the to-be-coated surface of the concrete PC beam with a primer; and (S3) after the primer is dried and solidified, coating the primer with an anti-slide wear-proof paint film, and standing until the anti-slide wear-proof paint film is dried and solidified. According to the preparation method, the to-be-coated surface of the concrete PC beam is preprocessed, so that the adhesive force of the coating to the PC beam is enhanced, and the construction quality is guaranteed; by coating the PC beam with the primer, the anti-slide wear-proof paint film is prevented from losing effect, a good bonding force is created for the surface of the PC beam and the subsequent coating layer, and a firm foundation of the coating layer is formed, so that the protection performance of the whole coating layer is improved; and by coating the primer with the anti-slide wear-proof paint film, the sliding caused due to the permeation of grease or impurities is prevented, and the service life of the coating layer is long.

Description

technical field [0001] The invention relates to an anti-slip and wear-resistant coating and a coating process thereof, in particular to a coating method of an anti-slip and wear-resistant coating for a concrete PC beam and a concrete PC beam. Background technique [0002] The original concrete prefabricated PC beam, the running surface of the concrete PC beam is a rough surface treated by rubbing, which has a high anti-skid value. Concrete has many capillary structures and is very easy to absorb water. The outer surface of concrete PC beams is eroded by many factors such as acid rain, urban exhaust gas emissions, dust, oil, and weak acid substances, which will undoubtedly accelerate the carbonization speed of concrete PC beams. Guided driving will cause obvious friction and wear marks on the guide part of the concrete PC beam. If effective protection is not taken for the wear mark part, its normal service life will be affected. [0003] Chongqing rail transit straddle-type ...
