Abstract

The invention relates to a graphene-based deodorizing pet urine pad and a manufacturing method thereof. The method comprises the following steps of: firstly, dispersing oxidized graphite into water, performing ultrasonic dispersion to form graphene oxide dispersion liquid A, then putting the oxidized graphene dispersion liquid A and phytic acid in a polytetrafluoroethylene reaction kettle for reaction, and freeze-drying to obtain a graphene sponge material B, using a catalyst for carrying out homogenizing treatment, using a coupling agent for surface modification treatment to obtain a graphene-based deodorant C, and mixing the graphene-based deodorant C with high-absorbency resin to obtain a mixture D, pressing the mixture D with toilet paper and wood pulp sequentially to obtain an absorption layer, compounding the absorption layer with non-woven fabric and bottom layer PE film to obtain the graphene-based deodorizing pet urine pad. The graphene-based deodorizing pet urine pad is non-toxic, is harmless, has no pungent smell, has no stimulation or corrosion effect on the skin of a pet, has outstanding deodorizing function and strong applicability, can remove various odors, has gooddispersibility and has good stability and durability.

Description

technical field [0001] The present invention relates to pet pee pads; more particularly, the present invention relates to graphene-based deodorant pet pee pads. In addition, the present invention also relates to a manufacturing method of the pet urine pad. Background technique [0002] At present, with the enrichment and satisfaction of people's material life, more and more people are pursuing spiritual sustenance, and pets just fill our spiritual dependence and comfort. Some psychiatrists also pointed out that pets are good for human mental health and play an irreplaceable role for human beings. But the smell of pet excrement is also very annoying. The main components of animal excrement are nitrogenous compounds, calcium, phosphorus, soluble nitrogen-free substances, crude fiber, other trace elements and some drugs. Varieties, feed ingredients and formulations, feeding methods, etc. vary. Nitrogen in pet excrement is mainly excreted in the form of organic nitrogen, in a...
