Problems solved by technology

[0003] The poor temperature resistance is manifested in two aspects, one is that it cannot meet the requirements of long-term use in the temperature range of 550-650 °C, and the other is that the high and low temperature resistance is poor, and the coating film is easy to crack;
[0004] The coating film has poor sinterability, and powder falling is easy to occur after high temperature;
[0005] Poor salt spray resistance, easy to rust and peel off paint in actual use

Embodiment Construction

[0014] A primer for high-temperature exhaust pipes of the present invention comprises the following components: epoxy-modified silicone resin, epoxy resin, filler, ferrochrome black powder, anti-settling agent and solvent. The above-mentioned epoxy-modified silicone resin is the main resin, and the epoxy resin is the modified resin, which helps to improve the anti-corrosion performance of the primer. The filler includes talcum powder, ceramic powder and mica, and the above-mentioned filler is helpful for secondary film formation and further improves anticorrosion performance.

[0015] The content of each component is: 10-30% of epoxy modified silicone resin, 1-5% of epoxy resin, 2-10% of talcum powder, 3-10% of ceramic powder, 3-10% of mica, chromium Iron black powder 1-2%, anti-settling agent 2-5%, solvent 20-30%.

[0016] The anti-sedimentation agent is fumed silica or bentonite, and the solvent is xylene or butyl ester, which help to prevent static delamination of the comp...

Abstract

The invention discloses a high-temperature exhaust pipe primer, including the following components: epoxy-modified silicone resin, epoxy resin, filler, chromium and iron black powder, anti-settling agents and solvents. The invention also discloses a high-temperature exhaust pipe finish, including the following components: methyl phenyl siloxane resin, epoxy resin, filler, chromium and iron black powder, anti-settling agents and solvents. The inventive primer and finish can achieve full temperature range of protection by regulation of primer and finish matching, has a good temperature resistance, coating sintering character and salt spray resistance, and can satisfy the requirement of long-term use in the temperature range of 550-650 DEG C. The coating is not easy to crack, and the phenomenon of powder dropping and rust stripping will not appear after high temperature.

Description

technical field [0001] The invention relates to a paint for an exhaust pipe, in particular to a primer and a finish paint for a high-temperature exhaust pipe. Background technique [0002] my country is a major producer of motorcycles. In 2008, the output of two-wheeled motorcycles has exceeded 25 million, and it is still increasing year by year. The exhaust pipes of motorcycles are generally made of low-carbon steel, and there are two types of surface protection methods: electroplating is mainly used for rider bikes, and coating is mainly used for underbone bikes. With the promulgation and implementation of the National III emission standards, the exhaust pipes of Cavaliers will not be able to be decorated and protected by electroplating, and the exhaust pipes of all motorcycles will be painted. In order to meet the market requirements, the coatings are basically imported from Japan. Even so, the protective effect of the exhaust pipe coating film is still not good. General...
