Abstract

The invention relates to a negative ion functional chip, a preparation method and a negative ion sanitary napkin. The preparation method of the negative ion functional chip comprises the following steps: uniformly adding 1-10 parts by weight of tourmaline powder, 1-10 parts by weight of medical stone powder, 0.5-1.5 parts by weight of carbomer or safflower seed gum, 5-15 parts by weight of carboxylated calcium lignosulphonate, 0.02-0.1 part by weight of copper citrate and 0.01-0.05 part by weight of silver citrate, 0.2-0.5 part of a nanometer titanium dioxide composite material into 50-120 parts of deionized water, performing stirring for 5-15 min at the rotating speed of 100-400 r / min, performing even mixing to obtain negative ion finishing liquid; putting a chip in the negative ion finishing liquid at the temperature of 40-50 DEG C to be soaked, the mass ratio of the chip to the negative ion finishing liquid being 1: (310), and the soaking time being 20-50 min; and then performing drying at a temperature of 40-60 DEG C for 1-5h to obtain the negative ion functional chip. The negative ion functional chip and the sanitary napkin prepared by the invention have the functions of instant absorption and softening, also have the effects of lasting bacteriostasis and anion release, and can dredge qi and blood, resist bacteria, diminish inflammation and relieve menstrual discomfort symptoms.

Description

technical field [0001] The invention relates to the technical field of disposable sanitary products, in particular to an anion functional chip, a preparation method and an anion sanitary napkin. Background technique [0002] Sanitary napkins, also known as sanitary napkins, are absorbent materials whose main materials are polymers and polymer composite paper formed from cotton, non-woven fabrics, pulp or composites of the above materials. Modern sanitary napkins are gradually developing towards multifunctionality, for example, by adding multiple functions to sanitary napkin chips to prepare functional sanitary napkin products. [0003] Chinese patent application CN108066808A discloses a negative ion sanitary napkin and its preparation method, including negative ion functional chip, the negative ion functional chip and the surface layer, absorber, bottom film, release paper, coating and quick and easy stickers according to the conventional sanitary napkin preparation process ...
