Problems solved by technology

But its disadvantages are: the coating on the metal plate is applied mechanically, so the adhesion between the coating and the metal plate is not good, and the coating often has bubbles and uneven coating, which cannot be done very well. It can play the role of waterproof and leakproof, so the process of this coating needs to be further improved

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] Such as figure 1 with figure 2 Shown, the coating on the surface of the cylinder gasket of the present embodiment, its formula consists of:

[0025] 78-85 parts of fluorine rubber, 15-25 parts of reinforcing agent, 8-15 parts of active magnesium oxide, 2-6 parts of vulcanizing agent, 4-8 parts of calcium hydroxide, 1-10 parts of pigment, the reinforcing agent can be The choices are: carbon black or diatomaceous earth. Of course, 1 to 5 parts of fluorine defoaming agent and 1 to 5 parts of fluorine leveling agent can also be added to the formula, and the above are parts by weight. The pigment can be determined according to the required requirements, such as molybdenum disulfide or phthalocyanine blue, etc. can be selected.

[0026] The preparation method of coating of the present invention comprises the following steps:

Abstract

The invention discloses a coating on a surface of a cylinder ring and a manufacturing method thereof. The coating on the surface of the cylinder ring is characterized in that a formula of the coating comprises the following components: 78-85 parts of fluororubber, 15-25 parts of reinforcing agent, 8-15 parts of active magnesium oxide, 2-6 parts of vulcanizing agent, 4-8 parts of calcium hydroxide and 1-10 parts of pigment. The method for manufacturing the coating is characterized by comprising the following steps: mixing sheets, preparing adhesive cement, coating by adopting a silk-screen method, drying and vulcanizing. Compared with the prior art, the formula of the coating has high adhesive firmness, bubbles do not exist on the coating, the coating can be prepared into various different colors according to the requirements, and the waterproof and leakproof effects can be effectively achieved. Moreover, according to the method for manufacturing the coating, the process is simple and stable, the silk-screen method is adopted, and a phenomenon that the bubbles occur in the coating is eliminated, so that the adhesive firmness between the coating and the sealing gasket is high, and the technical effect of achieving better waterproof and leakproof effects is achieved.

Description

technical field [0001] The invention relates to the technical field of metal cylinder pads, in particular to a coating on the surface of a cylinder pad and a manufacturing method thereof. Background technique [0002] There is an existing Chinese invention patent application with the application number 201010294599.6 titled "Processing Process for Coating Metal Plates for the Production of Metal Cylinder Gaskets in Small and Medium Batches of Various Varieties", which discloses a process in which metal plates several times the size of the metal gasket blank are processed. After mechanical cleaning, mechanical coating of adhesive, mechanical coating of fluororubber and mechanical coating of anti-sticking agent, mechanical cutting and cutting into suitable coated metal steel plates are used to make metal cylinder gaskets. The beneficial effect of the invention is that the production speed is fast, the quality is good and the stability is good, and it is beneficial to environme...
