Description
Technical Field
The invention relates to a stain-resistant odorless environment-friendly antibacterial antiviral shell paint and a preparation method thereof, and is applied to the field of flat-coating emulsion paint production.
Background
With the development of real estate industry and the new appearance of secondary home decoration in recent years, particularly for families with babies, the interior wall coating has high requirements particularly on the aspects of environmental protection, pollution resistance and other functionalities. Since the outbreak of new coronary pneumonia, the requirements of people on health are increased, and products which are more environment-friendly and have certain special functions, such as the characteristics of adsorbing and decomposing formaldehyde, resisting bacteria and the like, are needed. However, most interior wall coatings on the market are simple in decoration effect and cannot meet the pursuit of modern people on health and functionalization. Therefore, it is a urgent need to provide a shell paint with good performance, stain resistance, odor elimination, environmental protection, antibacterial, stain resistance, odor elimination, environmental protection, and antivirus, and a preparation method thereof.
Disclosure of Invention
In order to overcome the defects that the existing interior wall coating cannot have stain resistance, smell purification, environmental protection and antibacterial performance, the invention provides the stain-resistant, smell purification, environmental protection and antibacterial shell paint and the preparation method thereof.
The technical scheme of the invention is as follows:
a stain-resistant odorless environment-friendly antibacterial antiviral shell paint is mainly prepared from the following components in parts by mass:
the shell powder is one or any combination of more than two of 800-mesh 1000-mesh shell powder treated by a nano-pore technology.
The stain-resistant odorless environment-friendly antibacterial antiviral shell paint has the advantages that the preferable dispersoid is added into the system, and a special water-resistant structure (the contact angle is changed) can be formed on the film-forming surface of the paint, so that the surface has stronger hydrophobic, hydrophobic and stain-resistant effects, and the air permeability of a coating film is not influenced; the addition of special fillers such as shell powder enables a paint film to adsorb and decompose formaldehyde, purify air and eliminate certain peculiar smell, the shell powder is fine particles of the shell powder with the preferable mesh number, which are treated by a nano-pore technology (refer to the preparation process and optimization research of nano-pore activated shell powder, and the editor of wicker spring), and the fine particles are of a porous fibrous double helix structure, can effectively remove harmful substances such as free formaldehyde, benzene, ammonia and the like in the air and can purify the air due to peculiar smell generated by pets, smoking and garbage. The addition of the nano copper slurry enables the coating to have special effects of antibiosis, antivirus and the like; the copper sterilization mechanism is as follows: cu and water are subjected to chemical reaction under the aerobic condition to generate hydroxyl radicals (-OH) and active oxygen ions (O2-), which have strong redox effects and can destroy the cell proliferation capacity of microorganisms so as to inhibit microorganisms; the specific surface area of the nano copper is larger, so that chemical reaction is easier to occur; meanwhile, copper is one of trace elements necessary for human bodies and can be metabolized and absorbed by the human bodies, and silver is difficult to metabolize in the human bodies and can be enriched in the human bodies, so that nano silver is prohibited from being used as an antibacterial agent in Europe and America, and part of nano copper and the like are used for substitution. And the shell paint has the advantages of stain resistance, smell elimination, environmental protection and antibacterial property by matching with other optimized component types and dosage ratios. Detection and use prove that the stain-resistant odorless environment-friendly antibacterial antiviral conch paint is compact and hydrophobic in coating film, has an excellent stain-resistant effect, meets the requirements of superior products in GB/T9756-2018 and I type indexes in HG/T4756-. Compared with similar products in the same line, the stain-resistant odorless environment-friendly antibacterial antiviral shell paint has excellent stain-resistant effect and environment-friendly function, and is an ideal solution for the interior wall home decoration paint. The stain-resistant, odor-free, environment-friendly, antibacterial and antiviral shell paint has the viscosity of 95-105ku/25 ℃ and the pH of 8-10. This viscosity contributes to the workability of the product and the pH contributes to the storage stability of the product.
The film-forming assistant is a high-boiling-point film-forming assistant, and the boiling point of the film-forming assistant is more than or equal to 300 ℃.
Preferred high boiling film-forming aids are subject to high environmental requirements, especially low VOC requirements.
The thickening agent is one of cellulose ether thickening agents or polyurethane thickening agents or any combination of more than two of the cellulose ether thickening agents or the polyurethane thickening agents.
The preferred cellulose ether thickeners are those which are excellent in workability and storage stability, and the polyurethane thickeners are selected because they contribute to the paint film in terms of leveling and scrub resistance.
The titanium dioxide is rutile titanium dioxide.
The rutile titanium dioxide has higher covering power, higher weather resistance and whiteness.
The coarse whiting powder is 1800-plus 2000-mesh coarse whiting powder.
The preferred mesh of heavy calcium carbonate can generate synergistic effect with the selected titanium dioxide, so that the covering power of the product is further improved.
The bactericide is a formaldehyde-free bactericide.
The preferred bactericide is more environmentally friendly.
The preparation method of the stain-resistant, odor-free, environment-friendly, antibacterial and antiviral shell paint mainly comprises the following steps of:
(1) starting a stirrer, adjusting the stirring speed to 600-700r/min, sequentially adding water accounting for 18-20% of the total mass of the water into the stirrer, sequentially adding a pH regulator, a wetting agent, an ammonium salt dispersant, a defoaming agent, a thickening agent and bentonite, and dispersing until the thickening agent is completely dissolved;
(2) adjusting the rotation speed of the stirrer to 1500-1800r/min, sequentially adding titanium dioxide, shell powder, diatomite, coarse whiting powder and water accounting for 3-5% of the total mass of the water into the mixture obtained in the step (1), and dispersing for 20-25 min;
(3) and (3) regulating the rotation speed of the stirrer to 600-700r/min, sequentially adding the anionic modified acrylic emulsion, the environment-friendly wax emulsion, the antifreezing agent, the film-forming aid, the mildew preventive, the bactericide, the leveling agent, the water-resistant aid, the nano copper paste and the rest water into the mixture obtained in the step (2), and dispersing for 12-18min to obtain the stain-resistant odorless environment-friendly antibacterial antiviral shell paint.
The preparation method of the stain-resistant, odor-free, environment-friendly, antibacterial and antiviral shell paint is simple and convenient in steps and operation.
Compared with the prior art, the method has the following advantages:
1) the stain-resistant odorless environment-friendly antibacterial antiviral shell paint can form a special water-resistant structure (change a contact angle) on the film-forming surface of the paint by adding the optimal dispersion into the system, and has the advantages of stain resistance, odor purification, environment friendliness and antibacterial property by matching with other optimal component types and dosage proportions of the shell powder with optimal mesh number, the nano copper slurry and the like which are processed by a nano hole technology;
