technical field

The invention relates to a method for preparing and using a plant hydrophilic agent, which is used as an auxiliary agent for sanitary products.

Background technique

The existing hydrophilic agents are all chemically synthesized. When they are applied to sanitary products, because the hydrophilic agent is chemically synthesized, it will cause certain harm to the human body, and the preparation of the hydrophilic agent is complicated and the cost is relatively high. high.

SUMMARY OF THE INVENTION

In order to solve the problems existing in the prior art, the present invention provides a method for preparing and using a plant hydrophilic agent. The hydrophilic agent is a pure natural plant and is prepared in a physical way. Therefore, when it is applied to sanitary products, the sanitary products will not Harmful to the human body and the environment, the preparation raw materials of the hydrophilic agent can be easily obtained, and the production cost is low.

The technical scheme adopted in the present invention:

A method for preparing a plant hydrophilic agent, comprising production materials, wherein the production materials use at least one of beetroot, ficus leaf, sugar cane, ginger lotus flower, fruit, and longan core;

The preparation method includes:

Step S1: take 100 parts by weight of the production material, and pulverize or squeeze it for 3-10min to obtain an intermediate solution;

Step S2: filter the intermediate solution obtained in the step S1 through a 100-200 mesh screen to filter out impurities in the intermediate solution to obtain a hydrophilic agent.

The water content in the beetroot, ficus leaf, sugarcane, ginger lotus flower and fruit used in the production material is all greater than 50% wt.

Usually, when the production material is only longan core, in step S1, 100 parts of longan core are pulverized to obtain longan core powder, and 300-400 parts by weight of water is injected into the longan core powder and stirred to obtain an intermediate solution.

Preferably, when the production material only adopts at least one of the beetroot, ficus leaf, sugar cane, ginger lotus flower, and the water content of the production material is lower than 5%wt, step S1: take 100 parts by weight of the production material , pulverize it for 3-10min to obtain the end of production material, and mix all the end of production material obtained with alcohol to obtain an intermediate solution.

Further, the concentration of the alcohol is 50%-95%, and the alcohol is 300-500 parts by weight.

Further, between the S1 step and the S2 step, there is also an S1' step: the intermediate solution is allowed to stand for 1-7 natural days.

The preparation method of the hydrophilic agent further includes step S3: taking 200-300 parts by weight of alcohol, the alcohol concentration is 50%-95%, and mixing the alcohol with the hydrophilic agent in step S2 to obtain a finished hydrophilic agent.

The method for using the prepared hydrophilic agent is characterized in that it comprises a hydrophilic agent and a treated object, and the treated object includes a diaper core, cotton, silk, non-woven fabric, sanitary napkin core, rush, and dried plants fiber;

The method includes:

Step X1: Put the treated object into the hydrophilic agent until the treated object is completely soaked;

Step X2: Take out the treatment and let it dry.

Beneficial effects of the present invention:

In the present invention, the juice (intermediate solution) in the production material is squeezed out, and this part of the intermediate solution has the characteristics of a hydrophilic agent. Since the production material is a natural plant, the prepared hydrophilic agent does not contain any artificial chemical components. The prepared hydrophilic agent is mainly used in medical and sanitary products, and the sanitary products are in direct contact with the user, so the sanitary products treated by the present invention, on the basis of retaining the original fast water absorption efficiency, will not affect human skin at the same time. cause some damages.

The raw materials used for preparing the hydrophilic agent are natural plants, which are relatively easy to obtain, and the cost is relatively low, so the production cost of the hydrophilic agent is lower than that of the existing chemically synthesized hydrophilic agent.

Compared with the preparation method of the existing chemically synthesized hydrophilic agent, the method for preparing the hydrophilic agent provided by the present invention is simpler and easier to popularize and use, and the required preparation equipment does not require high technical content, and the cost is also lower. The disadvantage is that chemical fibers cannot use plant hydrophilic agents to achieve fast water absorption.

Detailed ways

The invention provides a method for preparing a plant hydrophilic agent, which mainly uses raw materials (production materials) as follows: beetroot, ficus leaf, sugarcane, ginger lotus flower, fruit, longan nucleus and the like.

The above production materials can be selected from a single item or a mixture of several items.

The fruits mentioned above include: oranges, apples, grapes, pears, peach, watermelon, dragon fruit, lychee, jujube, strawberry, orange, kiwi, mango, plum, pineapple, cantaloupe, melon, pomegranate, longan, etc.

Example 1

The production material is oranges.

Wash the oranges, with or without peeling, the total weight of the oranges is 5kg, crush or squeeze all the oranges (specifically, use a household food processor for processing), and the crushing or pressing time is 3- 10min, and the specific time is selected according to the degree of wall breaking of the orange (whether the juice in the orange is mostly separated from the orange), so as to obtain an intermediate solution (including the juice of the orange and various dander).

The intermediate solution is filtered through a 100-200 mesh screen (within the limited range, the smaller the mesh, the better), thereby filtering out impurities (dander) in the intermediate solution, and the obtained solution is the hydrophilic agent.

Since the color of the orange is orange, the corresponding obtained hydrophilic agent also contains the corresponding pigment, which is orange.

At this point, it can be used as a hydrophilic agent.

In order to prove that the obtained hydrophilic agent has the basic effect that the hydrophilic agent should have, the following experiments were made for verification:

First, the rush experiment:

Experimental materials: two identical transparent glass cups, both of which contain the same volume of water (the volume of water is about 300ml), and four rushes of 3cm length (the diameter of the rushes is about 3mm) , 100ml of hydrophilic agent prepared from oranges.

Experimental steps:

1. Take 2 rushes and place them in the hydrophilic agent for soaking. The soaking method is completely submerged in the hydrophilic agent, and the soaking time is 10min. The rush soaked in the hydrophilic agent is called the experimental rush, and the rush not soaked in the hydrophilic agent is the control rush.

2. Put the experimental rush out to dry (the color of the experimental rush is more yellow than the control rush).

3. The two glasses are the experimental glass and the control glass (both are filled with water), take 1 experimental rush and put it into the experimental glass, and at the same time take a control rush and put it into the control glass .

Observation of the experimental glass: After the experimental rush is placed in the experimental glass, the experimental rush floats on the water surface (but the experimental rush is entirely below the water surface), and after 30 seconds, the experimental rush sinks to the water. At the bottom of the experimental glass, the experimental rush floats up and down inside the glass at 68 seconds.

Observation of the control glass: After the control rush was placed in the control glass, the control rush floated on the water surface (the control rush as a whole was above the water surface), and after 10 minutes, the control rush was still floating on the water, and The control rush was entirely above the water surface.

The above experiments can clearly see that after the experimental rush is placed in the water, the experimental rush can quickly absorb water, so that the rush is quickly saturated with water, so that the rush is submerged under the water surface. Treated with a hydrophilic agent, it cannot absorb water quickly.

4. Both the experimental glass and the control glass are replaced with new water. Take 1 experimental rush, twist it into a ball with fingers and put it into the experimental glass, and at the same time take 1 control rush, twist it into a ball and put it into the control glass .

Observation of the experimental glass: After the spherical experimental rush fell into the experimental glass, the rush immediately sank to the bottom, and when the rush was sinking, the rush unfolded.

Observation of the control glass: After the spherical control rush is placed in the control glass, the control rush floats on the water surface (the control rush as a whole is above the water surface), and the rush is still spherical, slightly fluffy, 5 At 10 minutes, the control rush was still floating on the water surface, and the control rush was entirely above the water surface.

Through the above experiments, it can be concluded that the hydrophilicity of the rushes treated with the hydrophilic agent is significantly different from that of the untreated rushes.

Experimental materials: two groups of cotton wool (the mass of each cotton wool is 20 g), 200 ml of a hydrophilic agent prepared from oranges, a dropper, and pure water.

Experimental steps:

1. Take a ball of cotton wool and put it in the hydrophilic agent. Soak the cotton wool in the hydrophilic agent. The soaking time is 10 minutes. The cotton batting soaked with the hydrophilic agent is called the experimental cotton batting, and the cotton batting not soaking with the hydrophilic agent is the control cotton batting.

2. Put the experimental cotton wool outside to dry.

3. Drip water on the experimental cotton wool and the control cotton wool through a dropper.

It can be observed that when dripping water on the experimental cotton wool, the water is integrated into the experimental cotton wool within 1 second, and when dripping water on the control cotton wool, the water remains in the form of water droplets on the control cotton wool for 10-20 seconds before it is integrated into the cotton wool. Control cotton wool. Obviously, the hydrophilicity of the experimental cotton wool is better, which can also show that the prepared hydrophilic agent can play a corresponding effect.

It should be emphasized that any other combination of production materials (eg, combination of beetroot and ficus leaves, combination of sugar cane and apple, etc.) can be selected to prepare the hydrophilic agent.

The above hydrophilic agents can be further processed:

Inject alcohol into the hydrophilic agent, the concentration of the alcohol is 50%-95%, the ratio of the hydrophilic agent and the alcohol is 1:3-1:5, and then the above liquids are fully mixed.

The purpose of adding alcohol can effectively kill bacteria and viruses in the hydrophilic agent and prolong the shelf life of the hydrophilic agent.

The use effect of the finished hydrophilic agent obtained by adding alcohol is the same as the effect shown in the above experiments, and will not be repeated here.
