Description

KOH modified bagasse activated carbon adsorption type plant cat litter and preparation method thereof
Technical Field
The invention relates to a cleaning product for pet excrement, in particular to cat litter special for pet cats and a preparation method thereof.
Background
Along with the development and progress of society, people's life is also high-speed effective, and meanwhile, the social atmosphere of high rhythm brings pressure to people intangibly, and huge three-dimensional traffic network and information network have shortened people's spatial distance greatly for the pet economy is rapidly increased in recent years, wherein pet cat is hesitant to the convenient advantage of mode of raising, for example: when the work is on business, the food and the water can be independently placed at home under the condition of sufficient food and water; when the work is busy, the cat does not need too many companions, and only needs to feed cat food and then clean a cat litter box; the kittens are clean and have no body odor, so the kittens become the first choice of many breeders. The pet cat has strong territorial awareness, generally fear of strange environment and is mainly raised indoors, so that the problem of cat excretion is one of important considerations for a breeder. The problem is well solved by the advent of cat litter, but various cat litters in the current market are different in quality, and the owner mainly pays attention to the caking property, the water absorption property, the odor adsorption capacity, the dust property and the safety when selecting the cat litter.
After decades of research and development, cat litter is commonly available in the market and mainly comprises the following components: bentonite cat litter, silica gel cat litter, wood chip cat litter, paper chip cat litter, tofu cat litter, and the like. The bentonite cat litter has good water absorption and caking property but cannot be flushed into a toilet bowl, and the cat has harm and poor deodorization property when eating by mistake; the silica gel cat litter has super-strong absorption capacity, is convenient to clean in time, but has heavy peculiar smell and is easy to cause harm when being eaten by mistake; the wood chip cat litter is natural and non-irritant, has good adsorption performance, is easy to damp, and is easy to generate parasitic fleas and the like; the paper scrap cat litter is soft and small in particle, is gray after being wetted by urine, is well recognized and can be directly poured into a closestool for flushing, but has poor water absorption and caking property; the bean curd cat litter is good in water absorption and caking property, but is easy to stick to the bottom, so that the cleaning is inconvenient, and the adsorption is general. The consumer has great trouble in selecting.
Bagasse is one of byproducts in the sugar industry, and the development of additional value utilization of the bagasse conforms to the spirit of secondary pioneering of sugar industry in autonomous regions of Zhuang nationality in Guangxi province. Most bagasse material is used as a primary energy source in sugar and ethanol processing plants, including bio-electricity in advanced cogeneration plants. However, there remains a sustainable resource as a biorefinery, in particular for the production of ethanol, animal feed, furanic compounds, fibres for structural materials, composites, pulp and paper.
China is one of the world's largest sugar cane producing countries, and the ratio of producing sucrose to producing waste bagasse is 1: 3. The bagasse resources in China are rich, and in order to more effectively utilize sugar resource wastes, the bagasse is used for more optimized development of cat litter products. The bagasse has good water absorption, caking property, adsorbability and convenient treatment by utilizing the good natural property of the bagasse per se and adding proper modification, and can be directly flushed away by a toilet bowl. Provides a new direction in the aspect of comprehensive utilization of sugar resources, and well solves the problem of redevelopment of sugar industry waste.

The technical problem of the invention is realized by the following technical scheme:
the KOH modified bagasse activated carbon adsorption type plant cat litter is prepared by mixing the following components in parts by weight, molding, cooling, crushing and screening: 50-80 parts of bagasse modified super absorbent resin, 10-20 parts of corn flour, 1-5 parts of natural plant binder, 1-5 parts of silicon dioxide, 1-5 parts of KOH modified bagasse activated carbon and water, wherein the mass of the water accounts for 12-18% of the total mass of the mixed materials;
the KOH modified bagasse activated carbon is prepared by the method comprising the following steps:
(1) performing alkaline impregnation on bagasse at normal temperature for 20-30 h, continuously stirring during the impregnation, and drying at 100-110 ℃ after the impregnation; the alkaline impregnation solution is a 1-4 mol/L KOH aqueous solution, and the mass ratio of the KOH aqueous solution to the bagasse is 1-3: 1;
(2) calcining the bagasse subjected to soaking and drying at the high temperature of 550-600 ℃ for 70-90 min;
(3) calcining, washing and drying at 90-110 ℃;
