[0052] see Figure 4 , Figure 4 It is a flow chart of a method for preparing household paper provided in an embodiment of the present invention. The method for preparing household paper in this embodiment includes:
[0053] S101: Prepare at least one paper base layer;
[0054] The paper base layer is made of water-soluble paper with a water solubility of less than or equal to 30 seconds, preferably crepe paper without a wet strength agent, and its water solubility is less than or equal to 15 seconds. The water solubility test can adopt the test method of patent CN201110020031.X.
[0055] S102: Forming a first coating and a second coating at intervals on the surface of at least one paper substrate layer, the first coating and the second coating react with each other after being dissolved in water to produce functional components or release the first coating and the second coating / or functional ingredients in the second coating to produce the corresponding effect;

Embodiment 1
[0063] The household paper of the present embodiment comprises a paper base layer and a surface layer, and on the same surface of the paper base layer, the same surface of the paper base layer is separated and sprayed with a concentration of 1% citric acid aqueous solution and a paper base layer weight of 10%. The concentration of % is 2% sodium bicarbonate aqueous solution, which is characterized in that citric acid aqueous solution and sodium bicarbonate aqueous solution form the first coating on the paper base layer, that is, the citric acid aqueous solution area, and the blank area and the second coating, that is, sodium bicarbonate aqueous solution area, and the paper base layer sprayed with citric acid aqueous solution and sodium bicarbonate aqueous solution is laminated with the surface layer, so that the surface of the paper base layer is wrapped.
[0064] After the household paper of this embodiment is used, it is discarded in the toilet with water. Because the paper b...
Embodiment 2
[0066] The household paper of the present embodiment comprises a paper base layer and a surface layer, and on the same surface of the paper base layer, the concentration of 25% of the weight of the paper base layer is sprayed with a citric acid aqueous solution of 15% and a water-soluble adhesive Sodium bicarbonate coated with HPMCT (hydroxypropyl methylcellulose trimellitate) sensitive resin coated with 5% weight of the paper base layer, which is characterized by citric acid aqueous solution and sodium bicarbonate wrapped in HPMCT sensitive resin to form the first Coating i.e. citric acid aqueous solution area, blank area and second coating i.e. HPMCT sensitive resin wrapped sodium bicarbonate area, and sprayed with citric acid aqueous solution and sodium bicarbonate wrapped by HPMCT sensitive resin coated by water-soluble adhesive A paper substrate layer is laminated with a face layer such that the surface of the paper substrate layer is wrapped.
