Embodiment 1

[0050] Alcohol-soluble phenolic resin dipping glue with oil-water separation, its raw material components and weight percentages are as follows:

[0051] Oil-water separation phenolic resin LD-1 51.2%, methanol 48.8%.

[0052] A preparation method for oil-water separation fuel oil filter paper, comprising the following steps:

[0053] (1) Base paper preparation: Weigh mixed fibers composed of cellulose fibers and synthetic fibers and soak for 45 minutes to disintegrate. In the mixed fibers, cellulose fibers account for 80% and synthetic fibers account for 20% by weight. After the disintegration is completed, it is disintegrated by the disintegrator and then introduced into the disintegrating pulp tank. After being diluted with white water in the disintegrating pulp tank, it is refined by a conical refiner and then introduced into the forebear tank. The high-level box adjusts the wet strength agent diluted to 2% concentration to the flow rate of 5L / h with a metering pump and a...

Embodiment 2

[0057] Alcohol-soluble phenolic resin dipping glue with oil-water separation, its raw material components and weight percentages are as follows:

[0058] Oil-water separation phenolic resin LD-1 55%, methanol 45%.

[0059]A kind of preparation method of oil-water separation fuel oil filter paper, with embodiment 1, difference is:

[0060] In the mixed fibers in step (1), by weight, cellulose fibers account for 95%, and synthetic fibers account for 5%.

experiment example

[0061] Experimental example: Filtration accuracy experiment

[0062] Use FTH-1 sheet machine to make paper sample A and paper sample B respectively, paper sample A adopts pure wood pulp fiber, paper sample B adopts the mixed fiber of the embodiment 2 of the present invention, and in the mixed fiber by weight ratio, cellulose fiber accounts for 95% , synthetic fibers accounted for 5%. Then use the conventional heat-curable phenolic aldehyde and the dip coating glue of the present invention to coat respectively, and use the DT-100 multi-pass test bench to test the filtration accuracy after making paper samples with the same quantity. The base paper weight is 110g / m 2 , after coating with phenolic resin, the quantitative value is 135g / m 2 , respectively tested the air permeability, stiffness, burst resistance and filtration efficiency of each paper sample after dipping, and the results are shown in Table 1 below.

Abstract

The invention relates to an alcohol-soluble phenolic resin dip-coating glue liquid, oil-water separation fuel oil filter paper and a preparation method of the oil-water separation fuel oil filter paper. The oil-water separation fuel oil filter paper is prepared from the alcohol-soluble phenolic resin dip-coating glue liquid through dipping and curing, wherein the dipping amount is 20%-26%. The alcohol-soluble phenolic resin dip-coating glue liquid contains the following raw material components in percentage by weight: 45%-55% of oil-water separation phenolic resin LD-1 and 45%-55% of methanol, wherein the solid content of the oil-water separation phenolic resin LD-1 is 55%-60%. By adding synthetic fibers and carrying out dip-coating by virtue of the alcohol-soluble phenolic resin with an oil-water separation function, the obtained oil-water separation fuel oil filter paper has high filtration precision and is capable of filtering fine particulate matters mixed in fuel oil and is long in service life.

Description

technical field [0001] The invention belongs to the technical field of filter paper, and in particular relates to an alcohol-soluble phenolic resin dip coating glue solution, an oil-water separation fuel filter paper and a preparation method. Background technique [0002] With the standardization of automobile exhaust emission standards by national laws and regulations, the requirements for fuel quality are getting higher and higher. Combined with the current situation of oil products in our country, the fuel oil needs to be filtered during the use of automobiles to meet the needs of gas turbines. Now the fuel nozzles of automobiles are becoming more and more finely processed, and the atomization effect is getting better and better. If water is mixed into the fuel, the fuel nozzles will corrode, resulting in poor atomization effect, resulting in insufficient fuel combustion and excessive emissions. This phenomenon is especially evident in the field of commercial vehicles. ...
