Technical Field

[0001] The invention belongs to the technical field of indoor coatings, and in particular relates to a plant interior wall paint that releases negative oxygen ions and a preparation method thereof. Background Art

[0002] The concentration of negative oxygen ions is closely related to people's health. People need negative oxygen ions all the time, especially in today's increasingly serious pollution. According to environmentalists, when the concentration of negative oxygen ions in the air is below 20 per cubic centimeter, people will feel tired and dizzy; when the number of negative oxygen ions in the air is between 1,000 and 10,000 per cubic centimeter, people will feel calm and peaceful; when the number of negative oxygen ions in the air is above 10,000 per cubic centimeter, people will feel refreshed, comfortable and cozy, and it can play a role in calming, stopping asthma, eliminating fatigue, regulating nerves and other disease prevention and treatment effects.

[0003] The prior art CN201810012404.0 discloses a water-based forest negative oxygen ion interior wall paint and a preparation method thereof. The interior wall paint comprises the following raw materials in parts by weight: 0.1 to 0.3 parts of hydroxyethyl cellulose; 0.1 to 0.3 parts of pH regulator; 0.5 to 1.0 parts of dispersant; 15.0 to 20.0 parts of titanium dioxide; 5.0 to 10.0 parts of ultrafine heavy calcium carbonate; 3.0 to 5.0 parts of covering polymer; 1.0 to 2.0 parts of negative oxygen ion additive; 0.2 to 1.0 parts of mildewproof agent; 0.5 to 1.0 parts of preservative; 35 to 45.0 parts of odor-free emulsion; 0.3 to 0.5 parts of associative thickener; 1.0 to 2.0 parts of film-forming aid; 1.5 to 3.0 parts of defoaming agent; and 13.0 to 25.0 parts of deionized water. But its negative oxygen ion value is 2000 / cm 3 about.

[0004] Prior art CN202111245345.X discloses an environmentally friendly water-based diatom mud foaming material, and the key points of its technical solution are: an environmentally friendly water-based diatom mud foaming material, composed of the following raw materials in weight percentage: acrylic resin 1% to 8%; PU resin 9% to 20%; foaming agent 0.5% to 6%; diatomaceous earth powder 22% to 40%; defoamer 0.1% to 2.5%; PU leveling agent 0.1% to 2.5%; negative oxygen ion powder 1% to 8%; thickener 0.5% to 6%; acrylic leveling agent 0.1% to 2.5%; stabilizer 1% to 8%; charcoal 1% to 8%; flame retardant 8% to 15%. However, its negative oxygen ion value is relatively low, less than 2000 / cm 3 . Summary of the invention

[0005] The purpose of the present invention is to provide a plant interior wall paint which releases a high amount of negative oxygen ions and a preparation method thereof.

[0006] In order to achieve the above object, the technical solution of the present invention is as follows:

[0007] A plant interior wall paint for releasing negative oxygen ions comprises, by weight: 15-25 parts of potato glue, 10-25 parts of sweet potato glue, 15-25 parts of kiwi vine glue, 1-5 parts of peanut oil, 3-10 parts of milk, 2-6 parts of honey, 4-8 parts of nano titanium dioxide and 5-15 parts of negative oxygen ion powder; the potato glue and sweet potato glue are obtained by mixing potatoes and sweet potatoes with water, steaming and then crushing them evenly; the negative oxygen ion powder is a composite mineral powder that can produce negative oxygen ions.

[0008] Negative oxygen ion powder is a composite mineral powder that is artificially synthesized or formulated based on the principle of negative ions produced in nature. The mechanism of ionization of gas molecules in the air can increase the concentration of negative oxygen ions in the room, purify the air, eliminate odors and various harmful gases, and is also beneficial to the transportation, absorption and utilization of blood oxygen, promoting human metabolism, improving human immunity, enhancing human muscle energy, and regulating the balance of body functions.

[0009] The interior wall paint prepared by chemical emulsion is a dense film layer from a microscopic point of view. Some existing technologies use negative oxygen ion powder and nano titanium dioxide to prepare interior wall paint that releases negative oxygen ions, but the number of negative oxygen ions is far from meeting the requirements, and can only reach 2000 / cm at most. 3 About. The plant interior wall paint prepared by the present invention has a natural ecological plant source structure, which is a porous structure membrane from a microscopic point of view, which can better release the negative ions released by the negative oxygen ion powder, and the nano titanium dioxide can react with the photocatalyst through these pores to play a role in sterilization and formaldehyde removal and release of negative oxygen ions, further improving the degree of negative oxygen ion release by the negative oxygen ion powder. Compared with the interior wall paint prepared by chemical raw materials, to achieve the same number of negative oxygen ions, the negative oxygen ion powder and titanium dioxide added to the coating of the present invention are less than 60% of the interior wall paint prepared by chemical raw materials.

[0010] In one preferred embodiment, the preparation method of potato glue comprises the following steps: mixing potatoes and water, cooking at 100-110° C. for 30-50 min, cooling, dispersing and filtering to obtain potato glue.

[0011] In one preferred embodiment, the mass ratio of potatoes to water is 1:0.4-1.0.

[0012] In one preferred embodiment, the mass ratio of potatoes to water is 1:0.4-0.6.

[0013] In one preferred embodiment, the dispersion speed is 800-1000 rpm and the dispersion time is 20-30 min.

[0014] The potato glue in the present invention replaces the heavy calcium and light calcium in the conventional coating, plays a role of preservation and filling, and increases the concentration of the coating.

[0015] In one preferred embodiment, the preparation method of the sweet potato glue comprises the following steps: slicing the sweet potato and mixing with water, cooking at 100-110° C. for 30-50 min and then cooling, and then dispersing and filtering to obtain the sweet potato glue.

[0016] In one preferred embodiment, the mass ratio of sweet potato to water is 1:0.5-0.8.

[0017] Too much water will affect the concentration of pectin and cellulose. Too little water or the sweet potato gum concentration will be too high, which will affect dispersion and filtration, as well as the leveling and performance of the coating.

[0018] In one preferred embodiment, the mass ratio of sweet potato to water is 1:0.5-0.7.

[0019] In one preferred embodiment, the dispersion speed is 800-1000 rpm, and the dispersion time is 20-140 min.

[0020] Sweet potatoes are rich in pectin and cellulose, which play multiple roles in the present invention.

[0021] In one preferred embodiment, the preparation method of kiwi vine gum comprises the following steps: after crushing the kiwi vine, adding 2-3 kg of water at a ratio of 1 kg of kiwi vine powder, and soaking the kiwi vine powder in water for 4-6 days to obtain kiwi vine gum.

[0022] The kiwifruit vine gum contains very high plant cellulose, which plays the role of anti-cracking, weather resistance, strong adhesion, and non-differentiation in the present invention.

[0023] In one preferred embodiment, the method for preparing peanut oil comprises the following steps: frying the peanuts in a frying pan at about 60 to 80° C. for 15 to 20 minutes, and then squeezing the peanuts to obtain the peanut oil.

[0024] In the present invention, the performance of the wall paint reaches an optimal range after the raw materials are mixed in a suitable proportion through appropriate preparation temperature, time and water distribution ratio of the raw materials.

[0025] In one preferred embodiment, the nano titanium dioxide is anatase titanium dioxide colloid, preferably with a particle size of 20-50 nm.

[0026] Nano-titanium dioxide with a particle size below 50 nanometers can show good photocatalytic activity. Within a certain range, the smaller the particle size, the better the photocatalytic activity, but the smaller the better. The photogenerated particles generated on the surface of particles that are too small are more likely to recombine and are not conducive to photocatalytic efficiency.

[0027] In one preferred embodiment, the plant interior wall paint that releases negative oxygen ions also includes 10-20 parts of titanium dioxide slurry.

[0028] The paint film color of interior wall paint before adding titanium dioxide is golden yellow. In order to conform to the habits of most audiences, 10-20 parts of titanium dioxide are added, and the paint film color of interior wall paint reaches ordinary white.

[0029] In one preferred embodiment, the method for preparing the titanium dioxide slurry comprises the following steps: mixing titanium dioxide powder and water and dispersing the mixture at 800-1200 rpm for 25-30 min to obtain the titanium dioxide slurry.

[0030] In one preferred embodiment, the mass ratio of titanium dioxide to water is 1:0.3-0.4.

[0031] Honey contains many active ingredients collected from plants. After mixing with other components, it has the effect of anti-oxidation and maintaining the durability of the coating. When honey is added to the finished product, the temperature must not exceed 40°C, which can effectively maintain the active ingredients of honey and enable the functional powder to be released more effectively and naturally.

[0032] Milk is rich in calcium, and when combined with other components it can increase the stability of the paint. After the paint forms a film, the special smell of milk has the ability to calm the nerves, help with sleep, and help release negative oxygen ions in the paint, which plays a very good role.

[0033] In one of the preferred embodiments, the plant interior wall paint that releases negative oxygen ions also includes 0.5-1 parts of an antiseptic and antifungal agent.

[0034] Based on the same inventive concept, the present invention also claims a method for preparing the plant interior wall paint that releases negative oxygen ions, comprising the following steps:

[0035] Step 1: Mix potato glue, sweet potato glue, peanut oil and kiwi vine glue to obtain a mixture.

[0036] Step 2, adding negative oxygen ion powder and nano titanium dioxide to the mixture of step 1, and stirring evenly to obtain a semi-finished product;

[0037] Step 3: Add milk and honey to the semi-finished product of step 2 at 20-35°C, and stir evenly to obtain the finished product.

[0038] The product of the present invention has been continuously adjusted in formula and used on a large scale for many years, and finally a plant interior wall paint that releases negative oxygen ions with the following advantages is obtained:

[0039] 1. It has a fresh and pleasant fragrance;

[0040] 2. The painted space can remove all odors; the indoor air is better;

The preparation of raw materials is the same as in Example 1.

[0063] The plant interior wall paints releasing negative oxygen ions of Examples 1-4 were painted on the wall, and the number of negative oxygen ions was tested after drying. The results of Example 1 are as follows: Figure 1 As shown, the average number of negative oxygen ions detected in the air is 32173 / cm 3 .

[0064] The number of negative oxygen ions in Example 2-4 is no less than 22993 / cm 3 .

The sample had a strong antibacterial effect on the tested strains.

[0078] Comparative Example 1

[0079] Take 15 parts of sweet potato glue, 8 parts of peanut emulsion, 15 parts of glutinous rice glue, 18 parts of potato glue, 14 parts of soybean glue, 9 parts of lotus seed glue, 10 parts of kiwi vine glue, and 16 parts of titanium dioxide slurry. Mix according to the proportion, disperse at a high speed of 800 rpm, keep for 20 minutes, and make plant interior wall paint. Add 8 parts of nano titanium dioxide and 8 parts of negative oxygen ion ecological powder to the plant interior wall paint while stirring.

[0080] The preparation of sweet potato glue is as follows: wash, peel and slice the sweet potatoes. The mass ratio of sweet potato to water is 10:4. The water should not be too much, which will affect the concentration of pectin and cellulose, nor too little, as a high concentration will affect dispersion and filtration. Use high temperature processing, when the temperature reaches 100-110°C, keep the high temperature time for 30 to 40 minutes, wait for cooling below 40, use a high-speed disperser at 800 to 1000 rpm, and continue to disperse and filter at high speed for 20 to 25 minutes to obtain sweet potato glue.

[0081] The preparation of peanut emulsion is as follows: pour peanuts into a frying pan, maintain the temperature at 60-80°C, stir-fry for 15-20 minutes, and squeeze after cooling to obtain the emulsion.

[0082] The preparation of glutinous rice glue is as follows: glutinous rice and water (1:2, mass ratio) are mixed, soaked for 2 to 3 hours, ground into slurry, and when the temperature reaches 80 to 100° C., maintained for 10 to 15 minutes, during which time a mixer is used to continuously stir to achieve uniformity, and refined into a colloid.

[0083] The preparation of potato glue is as follows: wash and slice potatoes, mix potatoes and water (1:0.8, mass ratio), keep the temperature at 100-110°C for 30-40 minutes, cool, rotate at 800-1000 rpm, keep high-speed dispersion for 20-30 minutes, filter, and obtain potato glue.

[0084] The preparation of soybean gum is as follows: soybeans are peeled and crushed to a size of 200 mesh or more. Soybeans and water (1:1.5, mass ratio) are mixed, and when the temperature reaches 80-100°C, the mixture is stirred evenly with a stirrer for 10-15 minutes to obtain soybean gum.

[0085] The preparation of lotus seed gum is as follows: lotus seed powder and water (1:2.5, mass ratio) are mixed, and when the temperature reaches 80-100° C., the mixture is kept for 10-15 minutes, during which the mixture is stirred evenly with a mixer to obtain lotus seed gum.

[0087] The titanium dioxide slurry is prepared as follows: titanium dioxide powder and water (1:0.4, mass ratio) are mixed, and when the rotation speed reaches 800 to 1200 rpm, it is maintained for 25 to 30 minutes to obtain the titanium dioxide slurry.

[0088] The results showed that after adding negative oxygen ion ecological powder, the entire paint changed, becoming uneven and forming a paste, and could not be used as a paint film.

[0089] Comparative Example 2

[0090] According to the prior art CN201810012404.0, a water-based forest negative oxygen ion interior wall paint is prepared: the interior wall paint includes the following raw materials in parts by weight: 0.1 to 0.3 parts of hydroxyethyl cellulose; 0.1 to 0.3 parts of pH adjuster; 0.5 to 1.0 parts of dispersant; 15.0 to 20.0 parts of titanium dioxide; 5.0 to 10.0 parts of ultrafine heavy calcium carbonate; 3.0 to 5.0 parts of covering polymer; 1.0 to 2.0 parts of negative oxygen ion additive; 0.2 to 1.0 parts of mildewproof agent; 0.5 to 1.0 parts of preservative; 35 to 45.0 parts of odor-free emulsion; 0.3 to 0.5 parts of associative thickener; 1.0 to 2.0 parts of film-forming aid; 1.5 to 3.0 parts of defoaming agent; 13.0 to 25.0 parts of deionized water.

[0091] The results showed that the paint film was dense and non-porous at the microscopic level, and could only rely on the negative oxygen ion additives on the surface to work. The negative oxygen ion additives inside could not work, and the negative oxygen ion value was only 2000 / cm 3 about.

[0092] If the number of negative oxygen ions needs to reach more than 20,000, the amount of negative oxygen ion additives added must reach more than 20% of the total mass. However, if too much negative oxygen ion additives are added, the paint film will be uneven and the film-forming property will be poor. Moreover, more than 20% of the total mass of negative oxygen ion additives have obvious harmful effects on the human body, which exceeds the amount of addition specified by the industry.

[0093] After the coatings of Examples 1-4 and Comparative Example 2 were applied on the wall, the performance of the paint film was tested, and the results are shown in the following table:

[0094] Table 4 Performance of wall paint of embodiment and comparative example

[0095]

[0096]

[0097] Low temperature stability test was performed for three cycles.

[0098] Through the synergistic effect of various components, the plant interior wall paint releasing negative oxygen ions prepared by the present invention not only has good film-forming properties, but also has a negative oxygen ion release degree of up to 30,000, good antibacterial properties, and excellent formaldehyde removal effect. Moreover, the added amount of nano titanium dioxide and negative oxygen ion ecological powder is low, which plays a good health-care role on human health.

[0099] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
