Description
Technical Field
The invention relates to the technical field of coatings, in particular to a coating reinforcing agent, and a preparation method and a use method thereof.
Background
The coating material has an extremely important significance as an important building material for improving the function of the coating material. The microorganisms in the environment are respectively wide, the damage to various materials is ubiquitous, meanwhile, various infectious diseases caused by the action of the microorganisms cause great harm to human beings, and once the growth conditions are proper after the coating is polluted by the microorganisms, the microorganisms can grow and propagate in the coating in a large amount, so that the coating system has an unstable sign, which is mainly shown in that the viscosity of the coating system is reduced, the pigment is precipitated, the generated gas and the pH value are changed, and the like. Once a coating formed after the coating is coated by the paint is corroded by microorganisms, bacterial plaque is easily formed on the surface of the coating, so that the coating loses the adhesive capacity, the coating can seriously fall off, the protective function and the attractiveness and tidiness of the coating are directly influenced, and the practical value of the paint is reduced.
In order to increase the antibacterial performance of the coating, the current industry generally adopts the method that an antibacterial agent which has an antibacterial function and can stably exist in a coating is added, and the coating with the antibacterial function is prepared by certain process processing. However, the existing waterproof coating has good protection capability in the transverse direction (the direction parallel to the painting plane is defined as the transverse direction), but has weak moisture return resistance in the longitudinal direction (the direction perpendicular to the waterproof coating construction plane), is easy to age, is corroded by moisture return, has weak bacteria inhibition capability and the like, so that the technical problems of improving the antibacterial property and the persistence of the coating and delaying the aging of the coating are urgently needed to be solved by technical personnel in the field.

Further, the coating is any one of waterproof coating, water-based ink, heating coating, rubber coating, plugging coating, resin type coating, paint, fireproof coating, insulating paint, hydrophobic coating or heat-insulating coating.
A method for preparing a coating containing a reinforcing agent, comprising the steps of:
s1, weighing: weighing the raw materials according to the formula proportion for later use;
s2, preparing a material A: heating an organic silicon solvent to a temperature of more than 45 ℃ and less than 65 ℃ to form a material A;
s3, preparing a material B: mixing and stirring the raw materials except the organic silicon solvent and the coating in a dry container for 5-10 min to form a material B;
s4, mixing: mixing by adopting any one of the following methods to prepare the coating containing the reinforcing agent;
(1) sequentially adding the material A and the material B into a dry container, mixing and stirring for 10-30 min, keeping the temperature of the container at 40-50 ℃, and then adding the coating into the container and stirring for 10-60 min;
(2) and mixing the material A and the coating in a sealed state at normal temperature, stirring for 10-60 min, and adding the material B, and continuously stirring for 10-30 min.
A method of using a coating containing a reinforcing agent, comprising the steps of:
s1, brushing: coating or spraying the coating on the surface of an object according to the using method of the common coating;
s2, microwave sterilization: the coil with alternating current is contacted with or close to a coating plane, the number of turns of the coil is 2-5000 turns, the frequency of the alternating current is 1000 Hz-10 GHz, and the distance between the coil and the coating plane is 0-10 cm;
s3, ultrasonic sterilization: placing a magnet on the periphery or vertical surface of the alternating current coil in the step S2, or winding the alternating current coil above the magnet, switching on a power supply, and contacting and moving the alternating current coil on the surface of the coating to generate an ultrasonic signal;
s4, inductive light sterilization: and the plane of the coating is subjected to illumination treatment, so that the internal titanium dioxide and the light storage material can better realize bacteriostasis.
Further, the shape of the magnet in step S3 is any one of a cylindrical shape, a rectangular shape, a circular shape, a U-shape, or a ring shape.
Further, the illumination in step S4 is any one of natural light, LED light, incandescent light, or ultraviolet light.
The titanium dioxide in the invention has good photocatalytic sterilization effect, but when the light is weakened or the illumination disappears, the photocatalytic effect of the titanium dioxide disappears. Common mold and bacteria grow rapidly mainly in a dark or light-free environment, so that the light-storing powder can keep luminescence for a long time, and the light-storing powder transmits light with titanium dioxide, so that the titanium dioxide has continuous photocatalytic bacteriostatic ability. Meanwhile, the light wave emitted by the light-storing powder material has certain sterilization capability.
The reinforcing agent of the formula can be used for repairing cracks and has the capability of being widely combined with various existing waterproof coatings, common water-based coatings, floor paints and the like; the coating and the existing coating form a compound formula and are used for waterproof, reinforcing coating, decorative coating, floor paint and the like.
The principle of sterilization of the coating of the invention when in use is as follows:
microwave sterilization: the coil with alternating current is contacted with or close to the plane of the coating, the alternating current coil is used as a primary winding of the transformer, the electric conductor formed by electromagnetic wave inhibiting fibers in the coating is used as a secondary winding of the transformer of the alternating current coil, eddy current is generated in the coating, and microwave and electromagnetic wave heat is generated on the wall surface by the eddy current;
ultrasonic sterilization: when the alternating current coil is close to the paint, a directional magnetic field formed by the action of the magnet is generated in the paint, if the upper part of the paint is S and the lower part of the paint is N, magnetic powder in the paint can form corresponding S and N magnetic poles due to the S and N magnetic fields introduced by the coil. The alternating current coil generates alternating voltage, alternating current and an alternating magnetic field are generated inside, and the alternating magnetic field and the S and N magnetic fields of the magnet form alternating positive and negative superposition, so that a magnetic field with alternating S and N is induced in the coating. From the law of electromagnetic induction, when a changing magnetic field passes through a closed conductive loop (e.g., a coil), an alternating current potential and current (if not closed, only potential U, no current) are generated in the closed loop. Since the electromagnetic wave suppressing material is present in the paint, a certain resistance is formed, and thus a current is generated in the paint. Non-uniformity of the resistance in the coating (due to non-uniform density of the carbon fibers in the coating, and the impossibility of absolute uniformity of the thickness of the coating) causes the amplitude of the alternating current to vary when the alternating current coil is moved. The changing current thus changes the magnetic field strength of the paint itself and also of the coil, and the coil and the conductive fibers (electromagnetic wave suppressing material) in the paint vibrate within the range of the S, N poles of the magnet, thereby generating a vibrating ultrasonic signal.
The coating formula realized by the coating reinforcing agent can be used for spraying, brushing or printing the coating on an insulating or metal or ceramic or fiber base band or a fireproof base band, a waterproof and fireproof integrated base band, a silica gel film, a resin film, a plastic wall board, a composite material plate, an alloy material and the like (the base band can be understood as a film, an adhesive tape and the like) so as to enhance the sterilization performance or the waterproof performance or the stretching resistance or the belt shielding performance or the comprehensive sterilization, waterproof, stretching resistance and shielding performance of the base band;
