Embodiment 1
[0072] A kind of paper-based filter material raw paper that replaces mask melt-blown cloth and preparation method thereof, the steps are as follows:
[0073] (1) Mix the polylactic acid fiber accounting for 30% of the total fiber mass ratio with the softwood fiber with a beating degree of 30°SR accounting for 70% of the total fiber mass ratio, and add 0.5% of the total fiber mass as a papermaking wet strength agent polyamide Ammonia epichlorohydrin, and disperse evenly, make slurry;
[0074] (2) After diluting the slurry prepared in step (1) to a concentration of 0.025%, the paper machine is loaded, and the paper is formed by inclined wire forming to obtain a wet paper web;
[0075] (3) to the wet paper web surface that step (2) makes the negative ion fiber coating that above-mentioned making is sprayed, sprays upper surface, and spray amount is 3.5g / m in terms of solids 2 , and then according to the drying process of 30g / ㎡ sanitary napkin base paper and the subsequent paper-...
Embodiment 2
[0080] A kind of paper-based filter material raw paper that replaces mask melt-blown cloth and preparation method thereof, the steps are as follows:
[0081] (1) The polylactic acid fiber accounting for 40% of the total fiber mass ratio and the coniferous wood fiber with a beating degree of 30°SR accounting for 60% of the total fiber mass ratio are mixed, and 0.5% of the total fiber mass is added. Ammonia epichlorohydrin, and disperse evenly, make slurry;
[0082] (2) After diluting the slurry prepared in step (1) to a concentration of 0.025%, the paper machine is loaded, and the paper is formed by inclined wire forming to obtain a wet paper web;
[0083] (3) spray the negative ion fiber coating that embodiment 1 makes to the wet paper web surface that step (2) makes, spray the upper surface, and the spray amount is 3.5g / m in terms of solids 2 , and then according to the drying process of 30g / ㎡ sanitary napkin base paper and the subsequent paper-making process, the paper-base...
Embodiment 3
[0088]A kind of paper-based filter material raw paper that replaces mask melt-blown cloth and preparation method thereof, the steps are as follows:
[0089] (1) The polylactic acid fiber accounting for 20% of the total fiber mass ratio and the coniferous wood fiber accounting for 80% of the total fiber mass ratio with a beating degree of 30 ° SR are mixed, and 0.5% of the total fiber mass is added. Ammonia epichlorohydrin, and disperse evenly, make slurry;
[0090] (2) After diluting the slurry prepared in step (1) to a concentration of 0.025%, the paper machine is loaded, and the paper is formed by inclined wire forming to obtain a wet paper web;
