Abstract

The invention discloses a ceramic coating for coating the surface of a silencer sealing element and a using method. The coating comprises 10-18 parts of ceramic powder, 5-12 parts of perlite powder, 1-4 parts of a dispersant, 2-5 parts of an antifoaming agent, 20-23 parts of water, 10-12 parts of boron carbide, 12-14 parts of calcium aluminate cement, 5-8 parts of an adhesive, 80-100 parts of xylene, 25-35 parts of benzoin ethyl ether, 35-45 parts of dibenzoyl peroxide, 1-5 parts of a cross-linking agent and 10-20 parts of mercaptopropylmethyldimethoxysilane. The ceramic coating has the advantages of excellent wear resistance and stable properties, and can enhance the sealing performance and avoid abrasion after being coated on a sealing element, thereby solving the problem that the sealing performance is easily reduced in the use process due to poor wear resistance of the existing ceramic coating.

Description

technical field [0001] The invention relates to the field of ceramic coatings, in particular to a ceramic coating for coating the surface of a muffler sealing element and a use method thereof. Background technique [0002] The muffler refers to the air duct with noise transmission at the same time, which can use noise reduction devices such as pipes and elbows with sound-absorbing linings or pipes with sudden changes in cross-sectional area and other pipes with discontinuous acoustic impedance to attenuate the noise in the pipe or Reflect back. The former is called a resistive muffler, the latter is called a resistive muffler, and there are also impedance composite mufflers. [0003] At present, the wear resistance of the muffler sealing ring coating on the market is not good, which makes it easy to reduce the sealing performance during use. Contents of the invention [0004] The object of the present invention is to provide a ceramic coating for coating the surface of t...
