Problems solved by technology

The shortcomings of the above process are: 1. It is difficult to spray the oil repellant evenly on the same paper surface, and the spraying can only be sprayed on one side at the same time, and it is difficult to have the oil repellent effect on the other side; 2. The spraying method makes the oil repellant There is a large loss, which is not conducive to cost saving; 3. The spraying method is not conducive to controlling the retention of the oil repellent, and cannot guarantee a sufficient amount of the oil repellent; 4. Spraying the additive will affect the appearance and smoothness of the paper surface. Destruction; 5. It is difficult to achieve satisfactory oleophobic anti-seepage effect by combining oil repellent and surface glue sizing starch

preparation example Construction

[0025] A method for preparing oleophobic and anti-seepage ordinary filter rod forming paper, comprising the following steps: wood pulp crushing, adding fillers, flaking and beating, pulp blending, papermaking, net forming, pressing, front drying, surface sizing, Subsequent processes such as drying, coiling, slitting and packaging.

[0026] The preparation method of the oleophobic anti-seepage ordinary filter rod forming paper produced by the invention can ensure excellent oil-proof and water-proof properties, and also has biodegradability and food contact safety. The preparation method of the oleophobic anti-seepage ordinary filter plug forming paper produced by the present invention is measured according to the method of TAPPI T 559cm-02 for the oil-repellent performance of the paper. The preparation method of the oleophobic anti-seepage ordinary filter rod forming paper produced by the present invention measures the waterproof performance of the paper according to the water ...

Embodiment 1

[0029] Pulp ratio: Beimu brand 80% bleached softwood pulp, Parrot brand bleached hardwood pulp 20%; plus 20% light calcium pulp.

[0030] The two kinds of wood pulp plus light calcium were disintegrated by a hydropulper, soaked for 30 minutes, and then thawed and beaten, and the refining concentration was controlled at 4.0%. The degree of beating is controlled at 50-58°SR, and the wet weight is ≥4.5g. After the beating is completed, it is placed in the pulping tank.

[0031] Pulp blending: Prepare the ground wood pulp in a certain proportion in the pulp blending tank, mix, and then add wet strength agent PPE, the dosage is 10kg / t paper. Mix all together and dilute to a concentration of 2.5%.

[0032] Papermaking: Dilute the prepared slurry to a concentration of 1.0%, pump it to the forebay, and then go online with a slurry pump to form, press, and dry.

[0033] The surface sizing operation is: polyvinyl alcohol PVA dissolved concentration: 3.5%, the dosage is 15kg / t paper; a...

Abstract

The invention belongs to the fields of papermaking and tobacco industry and relates to a preparation method of oleophobic and impermeable common filter rod making paper. The preparation method of theoleophobic and impermeable common filter rod making paper comprises the following steps: wood pulp beating, filler adding, deflaking, pulping, blending, papermaking, net forming, squeezing, previous drying, surface sizing, late drying, coiling, slitting and packaging. According to the product, naturally degradable raw materials capable of being eaten safely are used on the basis that oilproof performance and seepageproof performance are guaranteed, and the oleophobic and impermeable common filter rod making paper is endowed with excellent degradability and food contact safety.

Description

technical field [0001] The invention belongs to the field of papermaking and tobacco industry, and relates to a preparation method of common filter rod forming paper. Background technique [0002] The preparation method of the filter rod forming paper is the special paper used for wrapping the filter material when processing the filter rod for cigarettes. Between the outer layer of tipping paper. There are mainly methods for preparing common filter rod forming paper and high permeability filter rod forming paper. The preparation method of filter plug paper that has no special requirements for air permeability is called the preparation method of ordinary filter plug paper; the preparation method of filter plug paper with clear requirements for air permeability is called the preparation method of high permeability filter plug paper. [0003] With the development of low-tar cigarettes, the microencapsulated essence technology for tobacco, the aroma of tobacco itself has been ...
