Description
Technical Field
The invention belongs to the technical field of air purification, and provides a deodorant for a toilet and a preparation method thereof.
Background
The public washroom is a place where people excrete in public places, and is a concentrated place where odor is generated. The public washroom has the advantages that due to the fact that daily people flow is large, air exhaust is not conducted, an air exhaust system is poor, and the like, some odor and peculiar smell are accumulated in the public washroom for a long time and cannot be volatilized out, so that air quality of the washroom is seriously reduced, the use of the public washroom is influenced, bacteria are easily bred in the public washroom, and physical and psychological health of a user is seriously influenced if a good ventilation system is not provided.
Whether the public washroom has odor or the odor concentration is a standard for measuring the quality of design, construction and management of the modern public washroom. The requirement of increasing density of people for the cleanliness of public toilets has not been met simply by increasing the number of times the toilet is cleaned or the frequency of ventilation. Thus, various methods and apparatuses for deodorizing a public washroom have been produced.
The method adopted for the built public washroom comprises burning incense, placing a deodorization bag for absorbing odor, placing spice, installing a wall hanging or vertical perfume sprayer and the like. However, these methods of deodorization are not very effective, as the deodorizing bag only absorbs the odor and has a limited absorption capacity, requiring periodic replacement. The perfume is placed or sprayed, so that the odor can be only covered, and the action time of spraying the perfume is short. The deodorizing microorganism bacterium can decompose and convert odor substances into odorless substances or inhibit the generation of odor substances to achieve the aim of deodorization, and has the advantages of no pollution and strong persistence. However, the deodorizing microbial agents on the market are mainly in liquid form, and are inconvenient to transport and store. Therefore, the application of the solid deodorant bacterium air purifying agent is more emphasized.
At present, air purifying agent technology, especially air purifying agent containing deodorizing bacteria, has achieved certain effect at home and abroad. Wherein, the Ponqanqing invents a compound deodorant for toilet deodorization and a preparation method thereof (Chinese invention patent application No. 201710904861.6), the compound deodorant mainly comprises a microbial deodorant bacterial agent and auxiliary components; wherein the microbial deodorant is Kluyveromyces marxianus, and the auxiliary components comprise sucrose, citric acid and tea polyphenols; wherein the concentration of Kluyveromyces marxianus is 1 × 107~1×109CFU/mL, wherein the contents of sucrose, citric acid and tea polyphenol are 5-20 g/L, 1-4 g/L and 0.5-5 g/L respectively; the composite deodorant can remove malodorous pollutants in the air of a toilet. In addition, Zhangjian invented a microbial deodorant (Chinese patent application No. 201510370735.8) for garbage, public washrooms and livestock and poultry farms, which contains Candida utilis, Lactobacillus plantarum, Streptococcus lactis, Saccharomyces cerevisiae, Streptococcus thermophilus, Bacillus licheniformis and Bacillus natto; the generated malodorous gases such as hydrogen sulfide and ammonia gas are absorbed and degraded, the malodors of garbage and garbage leachate are eliminated, the growth of putrefactive bacteria is inhibited, the generation of malodorous gases is fundamentally solved, and a garbage stacking environment capable of eliminating the malodors and preventing diseases from spreading is formed.
Therefore, the storage and transportation of the liquid deodorant agent in the prior art are inconvenient, the deodorant bacteria of the immobilized deodorant are difficult to release in the immobilized carrier and cannot effectively contact with the odor source of the odor agent, so that the deodorization effect is limited, and the development and the application of the deodorant agent are limited.

The invention creatively mixes the polyethylene glycol, the polyvinylpyrrolidone polymer and other auxiliary materials to form a slow-release framework material, and then granulates the mixture together with the deodorant bacteria to form the air purifying agent in the public washroom. The granular purifying agent can be placed in a public washroom or a flushing tank and a urinal, and due to the existence of the slow-release skeleton, the deodorizing bacteria in the purifying agent can be slowly released and fully contacted with odor and odor sources. Firstly, the odor can be thoroughly decomposed, secondly, the odor can be continuously purified in a slow process during the release of the deodorizing bacteria, and the service life of the air purifying agent is prolonged.
The invention also provides a deodorant for toilets prepared by the preparation method.
