Problems solved by technology

[0002] Toilet paper is one of the indispensable daily papers in people's daily life. In order to make the toilet paper softer, mechanical methods are usually used to wrinkle the paper and increase the softness of the toilet paper. There are many raw materials for making toilet paper, usually using cotton pulp, wood pulp, Bamboo pulp, grass pulp and other natural non-polluting raw materials, toilet paper requires non-toxic chemicals, no raw materials that irritate the skin, and no mold, virus, and bacterial residues. However, there are many types of toilet paper on the market at present. Due to different models, raw materials and production processes, toilet paper products are uneven. Domestic enterprises usually use cottonseed meal as the raw material for tissue paper production. However, due to the constraints of planting area and production cycle, this raw material is increasingly in short supply. Can not take into account the dry and wet strength, so further research on the above issues is needed

Embodiment 1

[0016] A preparation method of non-irritating high-tough toilet paper, comprising the following steps:

[0017] (1) In parts by weight, take 50 parts of dandelion stems, 28 parts of elm stems and leaves, and 20 parts of seaweed, mix them and crush them through a 350-mesh sieve, then add 14 parts of oak cork starch, and mix them evenly with a blower to get The mixed powder is ready for use;

[0018] (2) After cleaning the cork oak hopper, treat it at a temperature of 450°C for 1.5 hours, take it out and crush it through a 300-mesh sieve to obtain dry heat powder;

[0019] (3) Mix the mixed powder and dry heat powder at a weight ratio of 14:1, then add distilled water equivalent to 3.5 times its total weight, add it to the reaction kettle, heat it to a temperature of 88°C, and press it at a pressure of 4.6MPa Reaction under conditions for 9 hours, to obtain the mixed rubber;

Abstract

The invention belongs to the technical field of toilet paper for living, and particularly relates to a preparation method of non-stimulation high-toughness toilet paper. The method comprises the stepsof mixed powder preparation, dry hot powder preparation, mixed slurry preparation, compound slurry preparation and finished product preparation. Compared with the prior art, the method has the advantages that dandelion stalk and elm stalk leaves are used, the phenomenon that existing cottonseed meal raw materials are not sufficient is avoided, the stalk and the stalk leaves form stable colloid with modified vinylite, the toilet paper is not likely to be torn and good in tenacity, the elm stalk leaves are beneficial to fiber combination, the high water absorbing quality is achieved, paraffin and other toughening materials can be avoided, water in air can be adsorbed and locked in the fiber, the flexibility of the paper is improved, cork oak starch can further enhance the water absorbing quality of the elm stalk leaves, dye hot powder manufactured by cork oak shells can further enhance the pollution absorption performance of the dandelion stalk, no hazardous substance is contained, no stimulation to skin is caused, little environment pollution is caused in the production process, and the method is suitable for being used and popularized.
