Cat urine pH indicating material, pH indicating silica gel cat sand and preparation method thereof

Abstract

The invention relates to a pH indicating material, prepared pH indicating silica gel cat sand and a production method thereof, wherein the pH indicating material can indicate whether a pH value of pet urine is within a normal range. The silica gel cat sand containing the pH indicating material is a mixture of the pH indicating material and basic silica gel, wherein the pH indicating material accounts for 1-15 percent of the gross weight of the mixed silica gel cat sand, the pH indicating material uses silica gel as a carrier and contains a pH mixed indicator accounting for 0.025-2 percent of the gross weight of the pH indicating material and a water soluble polymer accounting for 0.5-20 percent of the gross weight of the pH indicating material, and the proportion by weight of methyl red and bromothymol blue in the pH mixed indicator is 1:12-1:1. Because the consistency of the pH indicating material and the basic silica gel in the materials is ensured, the pH indicating material in catsand products is uniformly distributed and can sensitively and stably indicate the acidity-basicity of the cat urine. The pH indicating material has low production cost, no toxin, no radioactivity, simple and easy preparation process as well as attractive appearance and color.

Description

technical field [0001] The invention relates to a pH indicating material capable of indicating whether the urine pH value of a pet (especially a cat) is within a normal range, a pH indicating silica gel cat litter and a production method thereof. Background technique [0002] According to the research of animal research institutions at home and abroad, the normal urine of cats is weakly acidic, with a pH value between 5.5 and 7.5. Many cats with disease have a urine pH that deviates from the normal range toward acidity or alkalinity. A common cause of abnormal urine pH in cats is feline lower urinary tract disease or feline urological syndrome. Urine with a high pH can easily lead to the formation of magnesium crystals, and urine with a low pH can easily lead to the formation of calcium crystals. Therefore, the health status of cats can be predicted by testing the pH value of cat urine, so that pet owners can prevent certain diseases of cats early. [0003] U.S. Patent No...

Problems solved by technology

[0005] However, because it cannot absorb urine itself, after the cat urinates, the urine will directly penetrate into a large amount of bentonite around it, and the bentonite immediately agglomerates due to water absorption, wrapping the pH indicating materials that account for a small number in quantity, affecting The color development and discoloration effect of the cat litter as a whole, even had to be manually sprinkled on the surface of the cat litter with pH indicator materials, but the problem brought about by this is that the cat will bury its own urine after excreting once, and then The pH indicator material on the surface will be buried in the bentonite and cause waste

Moreover, the pH indicator material disclosed in the above two patents is different from the basic cat litter due to the difference in material and density, which will lead to uneven distribution of the pH indicator material in the cat litter, and also affect the overall color development and discoloration effect of the cat litter.
