Mixed filler added filter paper for hydraulic filter

Abstract

The invention discloses a hydraulic filter filter paper with mixed fillers, which is prepared from the following raw materials in parts by weight: 50-55 mm of alkali-free ultrafine glass fiber of 3-5 mm, 55-60 mm of bleached coniferous wood pulp, appropriate amount of distilled water, Anionic polyacrylamide 0.8-1, an appropriate amount of concentrated sulfuric acid with a concentration of 98wt%, nano-titanium dioxide 10-12, a solid content of 30% iron ferric oxide colloid solution 20-25, an appropriate amount of absolute ethanol, and a solid content of 40wt% fluorine Silicon emulsion 60-65, PAE wet strength agent 0.8-1, white carbon black 7-8, mica powder 3-4, nano bamboo carbon powder 2-3, PVC resin powder 2-3, stearic acid emulsion 2-3. The surface of the filter paper made by the invention is fine and porous, has good gas permeability, has both strength and toughness, and has good effects of high temperature resistance and corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of filter paper, in particular to a hydraulic filter filter paper added with mixed fillers. Background technique [0002] Nowadays, our society is developing rapidly, and most enterprises will choose mechanical operation methods in the construction process. With the continuous improvement of science and technology, in terms of mechanical operation, enterprises have applied the construction method of mechatronics. During the use of machinery, no matter how carefully the operator installs and operates the equipment, it will inevitably cause varying degrees of pollution to the hydraulic oil. The maintenance of hydraulic oil will take a lot of time and money, so hydraulic oil has become a part of the mechanical use process. the most important part of the. During the use of the machine, the hydraulic oil is mainly used to penetrate other parts for operation. Due to the water, gas and dust mixed into the hydraul...

Problems solved by technology

However, the filter paper used in this article is ordinary filter paper, which does not have good high temperature aging resistance and corrosion resistance, and the filter paper will be damaged under pressure for a long time, resulting in filter failure, which will directly increase the production cost, and should be developed. A filter paper that can be easily replaced, not only can resist a certain pressure, has good strength, can be used in high temperature oil, but also can filter the moisture in the hydraulic oil and the mechanical impurities in the system, etc., at the same time save costs
