Embodiment 1

[0021] Weigh nano-bamboo charcoal: 25%; chitosan: 25%; nano-titanium dioxide: 8%; silica gel: 27%, add a total of 1700 grams to the three-dimensional mixer SBH-5 and mix at a speed of 6r / min, and the mixing time is 15 minutes. Finally, add potassium permanganate: 15%; 300 grams, under the same rotating speed, mix 20 minutes, be divided into 10 grams / bag after mixing, obtain the antibacterial refreshing agent A. Take a bag of antibacterial freshener and put it in a bag containing 0.1mg / m 3 In the moldy air environment of formaldehyde, benzene, ammonia and TVOC, the environmental space is 3m 3 , After 24 hours of testing, the odor content of the environmental space has dropped by 90%, and the bacteriostatic rate has reached 85%.

Embodiment 2

[0023] Weigh nano-bamboo charcoal: 10%; chitosan: 25%; nano-titanium dioxide: 15%; silica gel: 35%, add a total of 1700 grams to the three-dimensional mixer SBH-5 and mix at a speed of 10r / min, and the mixing time is 8 minutes for uniformity Finally, add potassium permanganate: 15%; 300 grams, under the same rotating speed, mix 15 minutes, after mixing evenly, be divided into 10 grams / bag, obtain antibacterial refreshing agent B. Take a bag of antibacterial freshener B and put it in a bag containing 0.1mg / m 3 In the moldy air environment of formaldehyde, benzene, ammonia and TVOC, the environmental space is 3m 3 , After 24 hours of testing, the odor content of the environmental space dropped by 80%, and the bacteriostasis rate reached 75%.

Embodiment 3

[0025] Weigh nano-bamboo charcoal: 30%; chitosan: 15%; nano-titanium dioxide: 5%; silica gel: 30%, add a total of 1600 grams to the three-dimensional mixer SBH-5 and mix at a speed of 6r / min, and the mixing time is 15 minutes. Finally, add potassium permanganate: 20%; 400 grams, under the same rotating speed, mix 20 minutes, after mixing uniformly, divide into 10 grams / bag, obtain antibacterial refreshing agent C. Take a bag of antibacterial freshener C and put it in a bag containing 0.1mg / m 3 In the moldy air environment of formaldehyde, benzene, ammonia and TVOC, the environmental space is 3m 3 After 24 hours of testing, the odor content in the environmental space decreased by 88%, and the bacteriostasis rate reached 78%.

Abstract

The invention relates to a nano antibacterial freshener and a preparation method thereof. The nano antibacterial freshener comprises the following components in weight percentage: 10-30% of nano charcoal, 5-20% of potassium permanganate, 15-25% of chitosan, 5-15% of nano titanium dioxide and 20-35% of silica gel. The preparation method of the nano antibacterial freshener comprises the following steps of: weighting each raw material according to the weight percentage and then pouring the raw materials except potassium permanganate into a three-dimensional mixer, wherein the mixing speed is 6-10 r / min, the mixing time is 5-15 min and the charge amount of a material barrel is 25-35%; after uniformly mixing, adding the potassium permanganate, mixing for 15-20 min in the same conditions, and uniformly mixing to obtain the nano antibacterial freshener. The nano antibacterial freshener has the properties of powerfully adsorbing and removing odor pollutants in the environment and the antibacterial property; moreover, the decomposed odor pollutants after adsorption can be strongly adsorbed and degraded by absorbent materials and are difficult to produce secondary pollution.

Description

technical field [0001] The invention relates to a solid freshener and a preparation method thereof, in particular to a nano freshener with antibacterial effect and a preparation method thereof. Background technique [0002] With the rapid development of the national economy and the rapid improvement of people's living standards, people's requirements for living, working and learning environments are also increasing. Various environmental pollution problems and harm to people's health have gradually attracted people's attention It is imminent to solve the deodorization and antibacterial problems of environments such as toilets, refrigerators, and living environments. After formaldehyde, TVOC, benzene, ammonia, sulfur dioxide, nitrogen oxides and other pollution, people began to care about the prevention and control of odor pollution. [0003] Odor pollutants refer to all gaseous substances that stimulate the olfactory organs to cause people's unpleasantness and damage the li...
