Description
Technical Field
The invention relates to the field of coatings, in particular to negative ion type healthy building interior wall latex for protecting and decorating building interior walls.
Background
In the beginning of the 70 s, developed countries began to develop "bad building syndrome" such as irritation, weakness, headache, hypomnesis, etc., and many data show that this is related to Volatile Organic Compounds (VOC) pollution in building coatings. At present, various countries in the world are dedicated to research and develop low-VOC latex paints, but in a latex paint system, various additives such as coalescing additives, leveling agents, antifreezing agents, anticorrosion bactericides and the like are inevitably required to be added, and therefore, the problem of reducing the VOC content under the condition of ensuring the quality of the latex paint is a troublesome problem. In addition, in recent years, the negative ion release material has been applied to the coating to release negative ions, kill bacteria, and purify air. However, because the anion releasing material has less resources and high cost, and the darker the color is, the better the anion releasing effect is, the key problem that must be solved is how to improve the color of the anion type coating product and exert low dosage and high efficiency.
Disclosure of Invention
In order to solve the problems, the invention aims to provide the negative ion type healthy building interior wall latex paint which has ultralow VOC content, good covering performance and can release negative ions to purify air.
The invention also aims to provide a preparation method of the negative ion type health building interior walllatex paint.
The purpose of the invention is realized as follows: an anion type health building interior wall latex paint comprises the following components (by weight percent): 20-50% of vinyl polymer emulsion, 0.2-0.9% of dispersing agent, 0.1-1.2% of wetting agent, 0.2-0.8% of defoaming agent, 16-25% of pigment, 0-24% of filler, 0.5-3% of anion release material, 0.2-3% of thickening agent, 0.05-1.2% of pH regulator and the balance of water.
The emulsion is a film-forming component of latex paint and determines the performance of a paint film. In order to reduce the VOC of the coating, the invention selects the pure acrylic emulsion, the styrene-acrylic emulsion and the tertiary vinegar emulsion with the zero VOC nuclear shell structure, thereby ensuring the better physical properties of the coating and effectively reducing the VOC to the lowest value. The core-shell structure emulsion refers to an emulsion obtained by taking a polymer as a 'seed' colloidal particle, adding another monomer and an initiator, and carrying out emulsion polymerization on the surface of latex. The composite latex is phase-separated but not separated, the middle is a cell core, the outer layer is a cell shell, an emulsifying layer is coated outside the shell to form a layered emulsion, namely a core-shell structure emulsion, and the network interpenetration occurs at a two-phase interface. The system is preferably an emulsion of soft core-hard shell particle structure, the core layer polymer provides softness, adhesion and cold brittleness resistance, the shell layer polymer provides abrasion resistance, heat resistance (non-stickiness) and solvent resistance, the Minimum Film Forming Temperature (MFFT) of the soft phase in each particle is low, a continuous film can be formed at a lower ambient temperature, and the hard phase in the particle gives the paint film excellent anti-blocking capability without adding any film forming auxiliary agent. Preferably, the emulsion with lower minimum film-forming temperature (MFFT) is used as a film-forming material of the anion type health building interior wall latex paint: the emulsion with the core-shell structure can be used for preparing low-PVC high-gloss paint; the emulsion with the non-core-shell structure can be used for preparing high PVC flat coating; the core-shell structure emulsion and the non-core-shell structure emulsion are mixed according to a certain proportion and can be used for preparing the medium PVC flat coating.
The latex paint is frequently used with more white pigment and filler, the paint is an environment-friendly system, and the paint ensures the performance of the paint and uses the pigment and filler with low content of harmful substances such as heavy metal and the like. The pigment is titanium dioxide, and the filler comprises heavy calcium carbonate, kaolin, talcum powder, superfine aluminum silicate and the like. Besides the white latex paint, other color pastes can be added into the system to prepare the latex paints with various colors.
Titanium dioxide: i.e. titanium dioxide (TiO)2) The white pigment is nontoxic, granular, small in particle size, high in whiteness, high in tinting strength and covering power, and mainly has two crystal forms: rutile and anatase. The system is preferably rutile titanium dioxide with fine particle size, easy dispersion and strong covering power, which is suitable for interior walls, such as DuPont company, and the optimal dosage is 16-25%.
Heavy calcium carbonate: white powder, one of the most commonly used fillers. It is tasteless and odorless, is not easy to pulverize, and can raise hardness and washing resistance of paint film. The main system is preferably 800 mesh heavy calcium carbonate, and the optimal dosage is 0-15%.
Kaolin: is a mineral polymer mainly comprising clay such as aluminum silicate kaolinite. Fine particles, good wetting dispersion stability and good suspension property, thereby being beneficial to preventing sedimentation. Added in a certain proportion, can save part of titanium white while ensuring the covering power. The kaolin clay with 1250 meshes is preferably used in the system, and the optimal dosage is 0-5%.
Talc powder: the main chemical component is hydrous magnesium silicate, and the talcum powder used in the emulsion paint can improve the workability, so that the coating is easy to brush, has good leveling property, enhances the durability of a coating film and the like. The main system is preferably 800 meshes of talcum powder, and the optimal dosage is 0-4%.
Ultra-fine aluminum silicate: is a functional filler, pure white amorphous loose superfine powder and low alkalinity. Because of small particle size, narrow particle size distribution and no precipitation delamination, the suspension property of the coating is greatly improved, the can opening effect is good, the hue of the coating is pure, the tinting strength is strong, and the covering power is improved. The superfine aluminum silicate with the particle size of 0.4-0.5 micron is preferably selected, the superfine aluminum silicate has the largest scattering capacity on incident light and has the highest covering power, and meanwhile, the smaller the particle size, the stronger the tinting strength, and the dispersibility and fineness index of the coating can be improved. The optimum amount of the active ingredient is 0 to 3%.
The system is used as a low VOC coating, and all selected auxiliaries are zero VOC or low in VOC value while the performance of products is ensured.
Dispersing agent: the system is preferably a polyacrylate dispersant or polymaleate dispersant with good dispersibility (wherein sodium and potassium salts have lower VOC than ammonium salts).
Wetting agent: in order to achieve better dispersion, improve the wetting of the binder and pigment, promote flowability, and inhibit foam generation, the system is preferably a poly (poly) phosphate wetting agent or/and a foam-inhibiting nonionic surfactant.
Thickening agent: the thickening agent is a rheological additive, can increase the viscosity of the coating after being added, and simultaneously endows the coating with excellent mechanical and physical and chemical stability, and plays a role in controlling the rheological property during construction. The thickening agent types selected by the system comprise a cellulose thickening agent, an alkali swelling acrylic emulsion thickening agent and a nonionic associative polyurethane thickening agent. The cellulose thickener mainly increases the medium-low shear viscosity of the emulsion paint, and has high thixotropy and high yield value. The alkali swelling acrylic emulsion thickener mainly improves medium and low shear viscosity, and has a large yield value and high thixotropy. And the nonionic associative polyurethane thickener has small yield value and good fluidity. The three thickening agents are selected from the system to be compounded for use, and the prepared coating is stable in viscosity, fine and plump in appearance, good in storage stability and good in can opening effect.
Defoaming agent: most of the various auxiliary agents in the latex paint belong to surfactants, so that the system is easy to foam or has factors for stabilizing bubbles. Stirring of the coating in the production process, spraying or roller coating in construction can increase the degree of freedom of a coating system to different degrees and help the generation of foams. Air in the foam can hinder the dispersion of the pigment and filler, bubble holes are left for the dry film, surface defects are caused, the appearance is damaged, and the water resistance of the paint film is influenced, so that a low-VOC defoaming agent which is suitable for the system is required to be used for solving the foaming problem. The system is preferably a polyether modified organic silicon emulsion defoamer with better compatibility, and the defect of defoaming performance can be solved by the synergistic action of the foam-inhibiting wetting agent.
The pH regulator is preferably non-volatile sodium hydroxide, potassium hydroxide or sodium carbonate.
The negative ion releasing material has positive and negative poles at two ends to constitute one permanent charged body, permanent electrode, and thus has pyroelectricity and piezoelectricity. When the external temperature or the external pressure is slightly changed, the ion distance and the bond angle are changed to induce dipole moment, so that a part of free charges bound on the surface of the unit body is released, the unit body is in a charged state or forms current in a closed loop, and an electric field and micro-current are formed around the unit body. Meanwhile, due to the existence of dipole moment, the anion paint additive has excellent far infrared function. Because each unit of the negative ion paint additive has a permanent electrode, when water molecules or oxygen molecules in the air contact with the permanent electrode, the permanent electrode instantaneously discharges, and the following reaction occurs:
releasing negative ions (H)3O2 -、O2 -) The formaldehyde, ammonia, benzene and other harmful gas particles with free positive charges can be neutralized and wrapped to form large particle groups and settle down, and the particles do not float in the air to cause harm to human health; the anion paint additive also has good peculiar smell removing effect, and the negative ions can neutralize oxygen free radicals and oxidizing gases (putrefactive peculiar smell) in the air, so that the formed electric field can decompose the peculiar smell of organic matters, thereby achieving the aim of purifying the air. The bacteria are mostly positively charged and are coated, neutralized or oxidized by negative ions in the airThe reduction effect (negative ions have higher activity) can destroy the activity of cell membranes or cell plasma active enzymes of bacteria, so that the bacteria lose the conditions of proliferation and reproduction, thereby achieving the aims of antibiosis and sterilization (escherichia coli, staphylococcus aureus, mould and the like). The preferable negative ion release material of the system is mirabilite powder produced by Taixing nanometer material factory in Chinese academy of sciences or/and negative ion of environment-friendly functional material produced by Beijing Lanuo environmental protection technology limited company.
