Xenotype abrasion-proof ceramic block with rubber and its preparing method

Abstract

The invention relates to a deformed wear-resistant ceramic block with rubber and the manufacturing method thereof. The invention is characterized in that a rubber layer, a metal sheet and a deformed ceramic block are arranged in sequence and then are vulcanized and adhered into a whole to obtain the deformed ceramic block with rubber. The detail producing method includes the following steps: A. ametal sheet is selected, the geometry size of the metal sheet is as same as that of the sticking surface of the deformed ceramic block; B. the high-temperature-resistance rubber is directly vulcanized onto the metal sheet by a vulcanizing steel die; C. the sticking surfaces of the metal sheet and the deformed ceramic block are cleaned, the mixed general high-temperature adhesive which can be bought in market is coated on the sticking surfaces which can be adhered into a whole in this way, the deformed wear-resistant ceramic block is obtained after the high-temperature adhesive is solidified. The invention has the advantages of simple structure, easy processing method, performances of wear and tear resistance, high temperature resistance of 300 DGE C and impact resistance, as well as good strength, thereby being not easy to be broken and peeled, thus the service life of the invention is greatly prolonged.

Description

technical field [0001] The invention relates to a special-shaped wear-resistant ceramic block with rubber and a production method thereof. Background technique [0002] Wear-resistant ceramic sheets are generally used on impeller pumps in fly ash pneumatic conveying systems in thermal power plants, cement industry pneumatic conveying systems, chemical industry conveying systems, and bulk cement transport ship pneumatic conveying (loading and unloading) systems. Two methods of direct vulcanization and glue bonding are used to make the rubber and the ceramic block form a whole. Since the direct vulcanization method needs to apply higher pressure, when the shape of the ceramic block is large, thin or irregular, the ceramics are easy to crack and break during vulcanization. The glue bonding method is to directly bond rubber and ceramic blocks as one with glue, but commercially available glue products of this type cannot withstand high temperatures above 150°C for a long time. ...

Problems solved by technology

Since the direct vulcanization method needs to apply high pressure, when the shape of the ceramic block is large, thin or irregular, the ceramic is easy to crack and break during vulcanization

The glue bonding method is to directly bond the rubber and the ceramic block together with glue, but such glue products on the market cannot withstand high temperatures above 150°C for a long time.

Neither of the above two methods can solve the bonding problem between the special-shaped ceramic block and the heat-resistant rubber
