Embodiment 1

[0038] Mix flame-blown microfiber glass wool, centrifugally rotating microfiber glass wool, glass fiber chopped strands with water and inorganic acid to make a pulp suspension. The concentration of the suspension is 1.0 wt%, and the pH value is 3. The inorganic acid used Be dilute hydrochloric acid; After deslagging and dilution (suspension concentration after dilution is 0.18wt%), send to Fourdrinier to form wet paper sheets with uniform thickness; Water-soluble acrylic binder (Shanghai Motian Chemical, model LD909) is diluted with water to a concentration of 3wt%, sprayed evenly or overflowed on wet paper, dried at 150°C for 50min, and the weight is 75g / m 2 Glass fiber liquid filter substrate, glass fiber filter substrate and non-woven fabric (gram weight is 50g / cm 2 ) compound on one side to obtain a liquid filter material.

[0039] See Table 1 for the mass percent of each component in the above-mentioned glass fiber liquid filter material.

Embodiment 2

[0043]Stir the flame-blown microfiber glass wool, glass fiber chopped strands, water and inorganic acid to make a pulp suspension evenly; after deslagging and dilution, send it to the fourdrinier machine to form a wet paper sheet with uniform thickness; Glue and drying process, the obtained grammage is 75g / m 2 The base material of the glass fiber liquid filter material, and then combined with the non-woven fabric on one side to obtain the liquid filter material. The difference between Example 2 and Example 1 is that no centrifugal rotating microfiber glass wool is added to the raw materials, and the mass percentages of each component in the glass fiber liquid filter material are shown in Table 2, and others refer to Example 1.

Embodiment 3

[0052] Mix flame-blown microfiber glass wool, centrifugally rotating microfiber glass wool, glass fiber chopped strands with water and inorganic acid to make a pulp suspension. The concentration of the suspension is 1.1wt%, and the pH value is 3. The inorganic acid used Be dilute sulfuric acid; After deslagging and dilution (suspension concentration after dilution is 0.15wt%), send to Fourdrinier to form wet paper sheets with uniform thickness; Water-soluble acrylic binder (Shanghai Motian Chemical, model LD909) was diluted with water to a concentration of 6wt%, sprayed evenly or overflowed onto wet paper, dried at 180°C for 30min, and obtained a grammage of 75g / m 2 Glass fiber liquid filter substrate, glass fiber filter substrate and non-woven fabric (weight is 35g / cm 2 ) double-sided composite to obtain a liquid filter material.

Abstract

The present invention discloses a high uniformity glass fiber liquid filtration material and a preparation method thereof, wherein the raw material components of the high uniformity glass fiber liquid filtration material comprise, by mass, 40-95 parts of flame blowing micro-fiber glass cotton, 1-30 parts of centrifugal rotation micro-fiber glass cotton, 1-20 parts of glass fiber short chopped fibers, and 3-10 parts of a water-soluble acrylic acid binder. According to the present invention, the flame blowing micro-fiber glass cotton, the centrifugal rotation micro-fiber glass cotton and the glass fiber short chopped fibers are matched as the raw material so as to make the diameter of the micro-fibers in the raw material stable, and the dispersed slurry is uniform, such that the molding uniformity of the filtration material is improved, the filtration material pore size distribution is uniform and centralized, the production process ability control Cpk is more than 1.67, the production cost is saved, the requirements of the small size engine on the high uniformity of the filtration material performance are adapted, and the service life of the filter is improved.

Description

technical field [0001] The invention relates to a high-uniformity glass fiber liquid filter material and a preparation method thereof, belonging to the field of filter materials. Background technique [0002] Automotive filters—air filters, oil filters, and fuel filters are an important part of ensuring the safe and reliable operation of automotive engines. Among them, the function of the fuel filter is to block the pollutant particles caused by fuel refining and processing from entering the engine combustion chamber, reduce the internal leakage caused by particle wear, thereby reducing the fuel injection volume, and protect the components of the engine fuel injection system from damage. Wear, ensure the normal operation of the engine, prolong the service life of other parts, and at the same time reduce the fuel consumption of the car, reduce the carbon black emission pollution of the car, and enhance the safety of driving. [0003] With the continuous development of the au...
