[0023] figure 1 A flow chart of a method for preparing oil-based paper provided by an embodiment of the present invention is illustrated. Such as figure 1 As shown, the preparation method of the cable oil-based paper that the embodiment of the present invention provides comprises:
[0024] Step 100: Disintegrate the bleached softwood pulp and the bleached hardwood pulp to obtain pulp pulp. The mass ratio of bleached softwood pulp and bleached hardwood pulp is (30~40): (60~80). It should be understood that pulping equipment such as a hydraulic pulper may be selected to decompose the bleached softwood pulp and the bleached hardwood pulp to obtain a pulped pulp. And the use of bleached softwood pulp and bleached hardwood pulp with a mass ratio of (30~40): (60~80) as raw materials can improve the physical properties of the oil-based paper and reduce the addition of chemicals, thereby reducing Cost of production.
[0025] Step 110: According to the medium-to-high concentration...
Embodiment 1
[0040] In this embodiment, a hydropulper is used to disintegrate bleached softwood pulp and bleached hardwood pulp. The thick knife used is a basalt knife, the beating concentration is 10%, the whitening agent is a stilbene derivative, and the wet strength agent It is melamine formaldehyde resin, the dry strength agent is polyacrylamide, and the neutral sizing agent is alkyl ketene dimer.
[0041] The preparation method of the cable oil-based paper in the present embodiment comprises:
[0042] Step 1: put 30 parts of bleached softwood pulp and 60 parts of bleached hardwood pulp into a hydropulper for disintegration to obtain a pulped pulp.
[0043] Step 2: Add 1 part of stilbene derivative, 0.5 part of melamine formaldehyde resin, and 0.5 part of polyacrylamide to the crushing slurry. Then, using the method of connecting the disintegrating machine and the disc refiner in series, selecting a beating concentration of 10%, and using a basalt knife to perform semi-free and semi-v...
Embodiment 2
[0048] In this embodiment, a hydropulper is used to disintegrate bleached softwood pulp and bleached hardwood pulp. The thick knife used is a small granite knife, the beating concentration is 20%, and the brightener is a phenylpyrazoline derivative and Benzimidazole derivatives, wet strength agent is polyamide, dry strength agent is cationic polyacrylamide, neutral sizing agent is alkyl ketene dimer.
[0049] The preparation method of the cable oil-based paper in the present embodiment comprises:
[0050] Step 1: Disintegrating 35 parts of bleached softwood pulp and 65 parts of bleached hardwood pulp to obtain pulping pulp.
[0051] Step 2: Add 1.25 parts of phenylpyrazoline derivatives and benzimidazole derivatives, 1.5 parts of polyamide, and 1 part of cationic polyacrylamide to the pulping slurry. Then, using a deflagging machine and a disc refiner in series, select a beating concentration of 20%, and use a small stone knife to perform semi-free and semi-viscous beating on...
