A kind of anti-mildew type bath filter with filter material, filter and preparation method thereof

technical field

The invention relates to a filter material for an anti-mildew type bath filter, a filter and a manufacturing method thereof.

Background technique

In the process of tap water disinfection in my country, chlorine gas is usually used as the main disinfection method. The use of chlorine gas for tap water disinfection has the characteristics of good disinfection effect and low cost. Chlorine gas dissolves in water and reacts with water to generate hypochlorous acid and hydrochloric acid. Hypochlorous acid plays a major role in the entire disinfection process. For odor-producing inorganic substances, it can completely oxidize and disinfect them. For living natural substances such as algae and bacteria, it can penetrate the cell wall and oxidize its enzyme system (enzyme is a biocatalyst) to make it lost. Activity, so that the life activities of bacteria are hindered and die. Residual chlorine refers to the effective chlorine remaining in the water after the water has been disinfected with chlorine and contacted for a certain period of time. Residual chlorine, as an effective means of sterilization and disinfection, is still used by more than 80% of water plants in the world. Therefore, a certain amount of residual chlorine must be maintained in municipal tap water to ensure the safety of microbial indicators of drinking water. However, when chlorine reacts with organic acids, many carcinogenic by-products, such as chloroform, are produced. More than a certain amount of chlorine itself will also cause many harm to the human body, and it has an unpleasant odor. If the residual chlorine concentration in tap water is too high, the main hazards are:

1. It is very irritating and is harmful to the respiratory system.

2. It is easy to react with organic substances in water to generate carcinogens such as chloroform and chloroform.

3. Contact with human protein will produce a reaction, resulting in a series of skin problems such as skin aging and rough skin.

4. The strong oxidizing property of residual chlorine is easy to react with the scalp protein, resulting in rough hair, scalp inflammation and other symptoms.

5. Residual chlorine is irritating to the skin of infants and young children, and it is prone to skin problems such as itching, redness, and allergies.

Therefore, it is an important measure to improve people's health to effectively remove residual chlorine in tap water before it is used. Especially in the process of residual chlorine elimination, no new harmful substances can be introduced and no secondary pollution can be generated. At present, the filter material on the market cannot be completely non-toxic and harmless, and the degree of adaptation between the filter and the shower head is low, and it cannot meet the functions of removing residual chlorine, mildew resistance, color recognition, and odor recognition at the same time. .

In a preferred embodiment of the present invention, the casing is made of plastic material, including ABS, PP, PE, and PC.

The present invention also provides a method for making an anti-mildew type bath filter, comprising the following steps:

① Preparation of filter material: take 100 parts by mass of vitamin C derivatives, 5-20 parts by mass of maltodextrin, 1 part by mass to 10 parts by mass of water-soluble polymer, and 0.1 part by mass to 3 parts by mass of food-grade Mildew agent, 0.1 to 10 parts by mass of natural essential oils or spices, 0.1 to 2 parts by mass of food-grade pigments, and an appropriate amount of water, fully mixed;

②Filling: Take a plastic round tube, press-inject the filter material prepared in step ① into the plastic round tube in the temperature range of 0 ℃ ~ 50 ℃, fully dry it, remove water; seal the plastic round tube with hot melt glue The tube is provided with a number of small holes in the plastic round tube.

In a preferred embodiment of the present invention, the dry mass of the filter material in the plastic circular tube is 90-110 g.

In a preferred embodiment of the present invention, a planetary stirrer is used in step (1), a standard mixing mode of rotation:revolution=7:3 is adopted, the average rotational speed is 800 rpm, and the mixing is performed for 5-15 minutes.

The selection of vitamin C derivatives is the basis of the present invention. In the process of residual chlorine elimination, residual chlorine is oxidizing, and all products with reducing properties can achieve the effect of residual chlorine elimination. However, in the process of purification of tap water, secondary pollution cannot be caused by harmful substances, so calcium sulfite, copper-zinc alloy and other products are mostly used. Derivatives of vitamin C have good biological reducibility and are non-toxic themselves. Instead, they have a certain whitening and protective effect on the skin, and have a certain auxiliary effect on solving skin problems. Therefore, the selection of vitamin C derivatives realizes the high-efficiency and non-toxic effects of the filter material in the present invention.

Maltodextrin, choosing a product with a certain water solubility can control the dissolution rate of vitamin C derivatives to a certain extent. In the present invention, the used maltodextrin mainly refers to the maltodextrin whose glucose value (DE value) is between 14% and 20%.

For water-soluble polymers, due to the good water solubility of maltodextrin, it is difficult to realize the preparation of long-acting filter materials.

In view of the problem that maltodextrin is easy to mold in the water body, which leads to the problem of water body pollution, a food-grade mildew inhibitor is further added to ensure the long-term effect of the filter material.

In order to improve the olfactory recognition of the product during use, natural fragrances or essential oils are further added to improve the user's sense of smell.

In order to improve the visual recognition of the product during use, food-grade pigments are further added to detect the use process of the filter material.

Compared with the background technology, the technical solution has the following advantages:

1. The filter material is non-toxic and anti-mildew. Through the slow-release behavior of vitamin C derivatives, no toxic substances are brought into the process of eliminating residual chlorine, resulting in secondary pollution; and the service life is long, 100 grams of filter material can eliminate More than 80% of the residual chlorine in 15 tons of tap water.

2. The preparation method is simple, and the plastic shell can be adapted to the shower cavity of various sizes and shapes, which is convenient to operate and has good practicability.

3. The filter material is used in bath products, and it is calculated from the beginning of use, and there is no mildew phenomenon within 30 days, and the anti-mildew effect is good.

4. The formulation of natural essential oils or essences and food-grade pigments not only satisfy the basic functions of residual chlorine and mildew resistance, but also have the functions of color recognition and odor recognition.
