Description

Filter material for anti-mildew type bath filter, filter and manufacturing 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 our country, chlorine gas is usually used as the main disinfection method. Chlorine gas used for tap water disinfection has the characteristics of good disinfection effect and low cost. Chlorine gas is soluble in water and reacts with water to form hypochlorous acid and hydrochloric acid. Hypochlorous acid plays a major role in the entire disinfection process. For inorganic substances that produce odor, 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 lose it. 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 chlorinated and disinfected for a certain period of time. Residual chlorine, as an effective means of sterilization and disinfection, is still used by more than 80% of the 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 in drinking water. However, when chlorine reacts with organic acids, many carcinogenic by-products, such as chloroform, will be produced. Exceeding a certain amount of chlorine itself will cause many harms to the human body, and it has an unpleasant smell. If the concentration of residual chlorine in tap water is too high, the main hazards are:

1. Very irritating and harmful to the respiratory system.

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

3. When in contact with human protein, it reacts, and a series of skin problems such as skin aging and rough skin appear.

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 is prone to skin problems such as itching, redness, and allergies.

Therefore, before tap water is used, it is an important measure to improve people's health to effectively remove residual chlorine in tap water. Especially in the process of residual chlorine elimination, new harmful substances cannot be introduced and secondary pollution cannot be generated. At present, the filter materials on the market cannot be completely non-toxic and harmless, and the degree of adaptation between the filter and the shower is low, and it cannot meet the functions of residual chlorine removal, mildew resistance, color recognition, and odor recognition at the same time. .

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a filter material for an anti-mildew type bath filter, a filter and a manufacturing method thereof, which solves the above-mentioned problems in the background technology.

The present invention also provides an anti-mildew type bath filter, including a shell and a filter material;

A number of small holes are opened on the shell, and the shell is installed in the inner cavity of the shower, and its shape matches the shape of the inner cavity of the shower;

The filter material is filled in the housing, and includes the following components in parts by mass: 100 parts of vitamin C derivatives; 5-20 parts of maltodextrin; 1-10 parts of water-soluble polymer; 0.1-3 parts of food grade antifungal agent ; 0.1-10 parts of natural essential oil or spice; 0.1-2 parts of food-grade pigment.

In a preferred embodiment of the present invention, the housing is made of plastic material, including ABS, PP, PE, 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, 1-10 parts by mass of water-soluble polymer, 0.1-3 parts by mass of food-grade Mold 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, 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 at a temperature range of 0°C to 50°C, fully dry and remove water; seal the plastic round tube with hot melt adhesive Tube, and a number of small holes are opened in the plastic round tube.

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

In a preferred embodiment of the present invention, in the step ①, the standard mixing mode of rotation:revolution=7:3 is adopted by a planetary mixer, and the average rotation 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 eliminating residual chlorine, residual chlorine is oxidizing, and the products of reduction can realize the effect of residual chlorine elimination. However, in the process of tap water purification, harmful substances cannot be caused to cause secondary pollution, so calcium sulfite, copper-zinc alloy and other products are often used. The derivatives of vitamin C have good bioreducibility and are non-toxic. 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 has realized the high efficiency and non-toxic effect of the filter material in the present invention.

For maltodextrin, choose a product with certain water solubility, which can control the dissolution rate of vitamin C derivatives to a certain extent. In the present invention, the maltodextrin used mainly refers to maltodextrin with a glucose value (DE value) of 14% to 20%.

For water-soluble polymers, due to the good water solubility of maltodextrin, it is difficult to realize the preparation of long-term filter materials. The present invention further adopts high-efficiency polymer slow-release materials to realize the controllable slow-release effect on vitamin C derivatives.

In view of maltodextrin, which is easy to mold in water and cause water pollution, a food-grade antifungal agent is further added to ensure the long-term effectiveness 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 of the filter material.

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

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

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

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

4. The formula of natural essential oils or flavors and food-grade pigments not only meets the basic functions of removing residual chlorine and preventing mildew, but also has functions such as color recognition and odor recognition.
