Abstract

The invention relates to a heat-resistant organic silicon red mark coating for railway vehicles and belongs to the field of coatings. The coating is prepared by mixing the following materials in percentage by weight: 40-47% of organic silicon resin solution, 20-28% of aluminium powder, 5-15% of talcum powder, 7-9% of red pigment, 10-15% of red pearl powder, 0-2% of fumed silica, 2-2.5% of tetrabutyl titanate, 0.6% of flatting agent and 0.1% of defoaming agent. The prepared coating provided by the invention has the characteristics as follows: simple coating process, long quality guarantee period, room temperature solidifying performance, excellent physical-chemical coating performance and long-term use performance at a temperature of 500 to 600 DEG C, and can satisfy the use requirement that the heat-resistant component of the railway vehicles has effects of caution and mark.

Description

technical field [0001] The invention relates to a high-temperature-resistant organosilicon red marking paint for rail vehicles, which belongs to the field of paint. Background technique [0002] The braking system of rail vehicles is one of the important factors related to the safe operation of rail vehicles, so it is necessary to check whether the braking system is loose before each vehicle runs. The standard of inspection is to see whether the position of the galvanized fasteners coated with marking paint has moved. As we all know, during the braking process of rail vehicles, a high temperature of 500-600°C will be generated instantaneously. The marking paint used as a mark must be able to withstand a high temperature of about 600°C and be bright red with a warning effect. [0003] At present, coatings with a temperature resistance exceeding 400°C can be divided into inorganic high temperature resistant coatings and silicone high temperature resistant coatings by binder. ...
