Embodiment 1

[0031] 1. Glue production process:

[0032] Mix 1kg of nitrile rubber, 2kg of butadiene rubber, 32g of sulfur accelerator, 51g of tackifier and 65g of filler rubber and auxiliary agents through a rubber mixer to prepare a mortar masterbatch; put the above glue in a glass container Dissolve the slurry masterbatch into 8L of cyclohexanone and n-butanol mixed solvent (the volume ratio of cyclohexanone and n-butanol is 1:1), and store it in a sealed place, and store it for 3 days for later use, during which period it is stirred periodically every 2 hours Once, the stirring speed is controlled at about 50r / min;

[0033] Second, the filter cloth treatment process:

[0034] 1) Pre-treat the filter cloth to ensure that the filter cloth is dry and clean;

[0035] 2) Mark the working ring surface;

[0036] 3) Evenly sprinkle the glue obtained in step 1 on the marking area;

[0037] 4) Put the filter cloth in a constant temperature environment, use a vulcanizing agent aqueous solutio...

Embodiment 2

[0038] Embodiment 2: Take the same mortar formula as in Example 1, and the steps of filter cloth sizing are also exactly the same as in Example 1. The only difference is that the novel vulcanization process proposed by the present invention is adopted, and the specific vulcanization process is operated as follows:

[0039] 1) Use hydrogen sulfide generator to take over to seal and fumigate the filter cloth sprinkled with glue, control the gas temperature in the fumigation room to be 63°C, and fumigate for 3 minutes;

[0040] 2) Take out the fumigated filter cloth, spray 25% hydrogen peroxide aqueous solution, and react for 5 minutes at room temperature;

[0041] 3) Heat and vulcanize the reacted filter cloth with steam in a sealed container, raise the temperature to 130°C, and vulcanize for 2 hours;

[0042] 4) Use 5%-10% sodium hydroxide aqueous solution to wash the vulcanized filter cloth for 2-3 times, then wash it with pure water for 2-3 times, and finally use 65°C and 100...

Abstract

The invention discloses a new type of glue-coated filter cloth, which is characterized in that flexible glue is coated on the joint between the existing filter cloth and the plate frame or filter plate, and then cross-linked and vulcanized to form a sealing layer. A new type of filter cloth bonded with a flexible sealing ring was obtained to solve the problem of poor sealing of the filter cloth; its production process includes the glue production process and the filter cloth treatment process, and the filter cloth treatment process includes cleaning the filter cloth, identification work Surface, glue coating and constant temperature vulcanization and other steps. The present invention aims at the deficiencies still existing in the sealing treatment process of the existing filter cloth, and mounts the rubber glue on the pressing surface of the filter cloth, and through a certain improved vulcanization process, forms a Flatter and softer sealing ring layer, the sealing ring layer has uniform vulcanization, high flatness, better anti-aging performance and higher repeated use rate, thus greatly increasing the sealing degree of the press joint of the filter cloth, thoroughly, Effectively and permanently solve the leakage problem of filter cloth.

Description

technical field [0001] The invention relates to the technical field of filter cloth sealing treatment, in particular to a novel rubberized filter cloth and a production process thereof. Background technique [0002] During the use of the filter cloth used in the existing filter press, due to the load on the filter cloth, the filter cloth fiber net is easily stretched and deformed by the gravity of the material, resulting in the appearance of the plate frame or the compression surface between the filter plate and the filter cloth. Loose, and due to the capillary phenomenon of the fiber gap, a certain amount of leakage will be caused, which will not only cause material loss, but may also cause finer material particles to reach the filtrate with the seepage, resulting in filtration failure. [0003] Aiming at the tightness of the filter cloth, the common practice is to place a sealing ring on the pressing surface of the filter cloth, which is costly and difficult to install; th...
