Problems solved by technology

[0003] In the existing small air conditioners, the operating noise of the air conditioner compressor is relatively large. In order to reduce the noise of the air conditioner compressor, the noise problem is generally solved through resonance analysis and system matching; now, some people also use the method of wrapping the compressor To solve the noise problem of the air conditioner compressor, but the effect of sound insulation is not good
Now, there is also a bag-type soundproof cover to isolate the noise of the air-conditioning compressor. A bag-type soundproof cover is disclosed in the patent document whose application date is 2008.10. The sound insulation cover includes the bag body and the filler inside the bag body. The filler is composed of a PVC layer, a damping plate layer and a glass wool layer. The sound insulation cover of this structure is specially designed for the bag body outside the filler, which improves the Cost of production and not easy to fit the soundproof cover over the A / C compressor

Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0013] See figure 1 and figure 2 , The air conditioner compressor soundproof cover includes a side surface 1 surrounded by soundproof sheets, an upper cover 2 made of soundproof sheets and a lower cover 3 made of soundproof sheets.

[0014] The upper cover 2 is square, so it is easy to manufacture, and three sides protrude from the side 1, which can completely cover the upper edge of the side. Therefore, not only the upper cover 2 is not easy to fall into the side 1, but also the sound insulation effect is improved. . A connecting part 4 is provided between one side of the upper cover 2 and the upper edge of the side 1, so that the upper cover will not fall off the side, which is convenient for transportation; the upper cover 2 is provided with two parallel cutouts 5, and the cutouts 5 are formed from the connecting part. The oppo...

Abstract

The invention discloses a method for manufacturing a calendered rubber plate. The method comprises the following steps: 1, mixing raw materials comprising butyl rubber, one or a mixture of two or three of mica, vermiculite and graphite, a fire retardant, one or a mixture of two or three of BaSO4, iron and iron oxide, a fiber, carbon black, a tackifier, a softener and a rubber assistant, and mix-milling the raw materials according to a mix-milling temperature of 120-170DEG C, a mix-milling pressure of 8-10MPa and a mix-milling time of 6-12min; and 2, calendering the mix-milled product in a calender according to a calendering temperature of 50-80DEG C and a linear velocity of 8-12m / min. The technology for manufacturing the calendered rubber plate used in a sound insulation cover has the advantages of simple process and low cost, and the sound insulation effect of the sound insulation cover manufactured from the calendered rubber plate is good.

Description

[0001] This application is a divisional application of the application number 201010153929.X and the application date is April 16, 2010. The name of the invention is an air conditioner compressor sound insulation cover and its manufacturing method. technical field [0002] The present invention relates to a method of manufacturing calendered rubber sheets for use in acoustic enclosures. Background technique [0003] In the existing small air conditioners, the operating noise of the air conditioner compressor is relatively large. In order to reduce the noise of the air conditioner compressor, the noise problem is generally solved through resonance analysis and system matching; now, some people also use the method of wrapping the compressor To solve the noise problem of the air conditioner compressor, but the effect of sound insulation is not good. Now, there is also a bag-type soundproof cover to isolate the noise of the air-conditioning compressor. A bag-type soundproof cove...
