Detailed Description
In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The method aims to solve the problems that the traditional net pasting mode is adopted to paste the net in the prior art, the production speed of the ceramic plate is difficult to match, and the production efficiency and the production cost are seriously influenced.
In order to solve the problems of the prior art, the present embodiment provides an adhesive formula and a ceramic plate mesh pasting method, wherein a first curing is performed after an adhesive coating process is performed between the ceramic plate and a mesh cloth based on the adhesive formula, so that the surface of the ceramic plate can be dry, and the ceramic plate and the mesh cloth can be efficiently bonded without increasing additional production cost.
In practice, the invention provides a binder formulation consisting of a conventional adhesive and a UV adhesive. The proportion range of the conventional adhesive and the UV adhesive is 1/9-11/3, wherein the conventional adhesive can be any non-UV adhesive formula glue in the prior art, and the UV adhesive can be any UV adhesive in the prior art. As long as the proportion of the conventional adhesive and the UV adhesive is more than 1/9 and less than 11/3, the adhesive can be prepared, the adhesive formula of the invention is low in cost because various expensive metal compounds (such as tungsten boride, barium sulfate, magnesium silicide) and the like are not added, the curing time is long at normal temperature, the adhesive property is very strong after the curing, the adhesive disclosed by the invention is combined with the photosensitive characteristic of the UV adhesive, the surface of the adhesive can quickly reach finger drying under the irradiation of ultraviolet rays, and the ultra-strong adhesive property of the conventional adhesive is combined, so that the glue finally prepared from the adhesive can reach good adhesive property. When the adhesive is coated on the surface of an object, the surface of the ceramic plate adhered with the grid cloth can be quickly cured under the irradiation of ultraviolet light, and the inside of the adhesive can be naturally cured for a certain time, so that efficient adhesion is finally realized.
In one implementation, the conventional adhesive is a thermosetting adhesive or a thermoplastic resin or a composite adhesive blended by the thermosetting adhesive and the thermoplastic resin. The thermosetting adhesive can be unsaturated polyester, polyurethane resin, melamine resin, furan resin, organic silicon resin, polyimide and the like, and the thermoplastic resin can be polyvinyl alcohol, polyvinyl acetal, polyvinyl acetate, polyacrylate, polyurethane, polyester, polyamide and cellulose derivative. In this embodiment, each 100 g of the conventional adhesive may be prepared from 100 g of any thermosetting adhesive, may be prepared from 100 g of any thermoplastic resin, and may be prepared by mixing 50 g of any thermosetting adhesive and 50 g of any thermoplastic resin.
In one implementation, the UV adhesive consists of silicone modified epoxy acrylate, urethane acrylate, trimethylolpropane trimethacrylate, adhesion promoter, and 2-hydroxy-2-methyl-1-phenyl acetone. In this example, each 100 grams of UV adhesive was composed of 50 grams of silicone modified epoxy acrylate, 20 grams of urethane acrylate, 25 grams of trimethylolpropane trimethacrylate, 2 grams of adhesion promoter, and 3 grams of 2-hydroxy-2-methyl-1-phenyl acetone.
With the above binder formulation, the binder formulation can be applied to ceramic plate screening processes. Specifically, as shown in fig. 1, the ceramic plate pasting method of the binder formulation in the present embodiment includes the steps of:
s100, obtaining a ceramic plate formed by firing;
s200, performing bonding coating treatment on the back surface of the ceramic plate based on the binder formula, and adhering a grid cloth on the back surface of the ceramic plate subjected to the bonding coating treatment;
s300, carrying out primary curing treatment on the ceramic plate adhered with the grid cloth, and then carrying out secondary curing treatment on the ceramic plate subjected to the primary curing treatment to obtain a finished product of the grid-adhered ceramic plate; wherein the time of the first curing treatment is less than the time of the second curing treatment.
In specific implementation, this embodiment first obtains a ceramic plate formed by firing, where the ceramic plate is made of zirconia or alumina, and has extremely strong weather resistance, and no influence is caused on the surface and the substrate by sunlight, rain (even acid rain), or moisture. Ultraviolet irradiation resistance and color stability, and can completely reach 4-5 international gray levels. The main characteristics of the ceramic plate are: impact resistance, scratch resistance, wear resistance, easy cleaning, moisture resistance, fire resistance, static resistance and chemical corrosion resistance. The ceramic plate can expand with heat and contract with cold under the influence of the ambient temperature, so that the ceramic plate is cracked. The grid cloth has the characteristics of high strength, corrosion resistance and good alkali resistance, and can avoid common problems of top surface cracking, fine lines, bulge water leakage and the like. After the ceramic plate obtained by sintering is formed, the back of the ceramic plate is subjected to cleaning treatment such as dust removal, and then the back of the ceramic plate is subjected to bonding coating treatment, wherein the bonding coating treatment performed on the back of the ceramic plate can be performed in a manual mode by coating one layer of base coat on the back of the ceramic plate, and can also be performed in a mechanical mode by coating one layer of base coat on the back of the ceramic plate. The primer is the adhesive formula. After the back surface of the ceramic plate is subjected to bonding coating treatment, mesh cloth can be pasted on the back surface of the ceramic plate after the bonding coating treatment, and the mesh cloth can be glass fiber mesh cloth, nylon mesh cloth, carbon fiber cloth, aramid fiber cloth, polypropylene fiber cloth, polyester fiber cloth, vinylon fiber cloth and aluminum silicate ceramic fiber cloth. In practice, because the ceramic plate with the mesh is laid on a wall surface or a cooking bench in the decoration process, the surface of the ceramic plate with the mesh cloth needs to be as flat as possible to facilitate the construction of workers. Therefore, after the mesh cloth is attached to the back surface of the ceramic plate after the bonding coating process, the attached mesh needs to be scraped off so that the back surface of the ceramic plate to which the mesh cloth is attached is kept flat. The primer in the traditional technology is pure common glue, so that the curing time of the primer between the bonding grid cloth and the ceramic plate is longer in practice, the primer usually needs to be cured for seven days, and the primer needs to be placed on a brick storage rack for natural drying, so that the tool cost is increased invisibly; furthermore, because the net ceramic plate is not dried out and has viscosity, the net ceramic plate needs to be placed at intervals, so that a large area is needed for placing a large amount of uncured net ceramic plates at one time; or a drying production line is added for heating and curing in order to accelerate the curing time, thus the generation investment cost is increased virtually. The primer in the embodiment of the invention contains the components of the UV glue, and various expensive metal compounds (such as tungsten boride, barium sulfate and magnesium silicide) are not added, so the cost is low, the surface of the ceramic plate can quickly reach finger drying when the first curing is carried out, but the adhesive between the ceramic plate and the grid cloth is not completely cured, and then the second curing treatment is carried out under the condition of not increasing production lines and equipment. Obtaining a finished product of the net ceramic plate; the secondary curing is handled mainly with net cloth with the primer between the ceramic plate carries out thorough curing, the time of curing for the first time is less than the time of curing for the second time, it is right then to mean paste the surface that has the ceramic plate and carry out the primary cure after, can not produce the adhesion between the ceramic plate, need not through the storing frame will the ceramic plate separates to place, can pile up and place a period, also need not to increase extra production line for finally obtain the off-the-shelf overall cost reduction of subsides net ceramic plate.
In one implementation mode, the step of performing the bonding coating treatment on the back surface of the ceramic plate specifically refers to rolling or curtain coating a layer of primer prepared by the binder formula on the back surface of the ceramic plate after the cleaning treatment. The coating amount of the primer is 60-400 g/m2. In addition, after the primer is coated on the ceramic plate, the primer needs to be scraped off, so that the primer is tiled on the ceramic plate with uniform thickness, and subsequent decoration construction is facilitated.
In one implementation, the first curing treatment of the ceramic plate to which the mesh cloth is attached is specifically ultraviolet light irradiation of the surface of the ceramic plate to which the mesh cloth is attached, so that the surface of the ceramic plate is rapidly cured. Because the adhesive contains the components of the adhesive, and the adhesive can be converted from a liquid state into a solid state in a short time after absorbing ultraviolet light under the irradiation of ultraviolet rays, in order to accelerate the curing speed of the surface of the ceramic plate adhered with the grid cloth, ultraviolet curing equipment is adopted to carry out ultraviolet light irradiation on the surface of the ceramic plate, so that the adhesive with the mesh parts on the back surface of the net ceramic plate can quickly reach finger drying, and the adhesive is wrapped by the part without the mesh holes on the back surface of the net ceramic plate, so that the back surface of the net ceramic plate is not provided with the adhesive any more, the net ceramic plates can be stacked and placed, and a storage rack is not required to be added to air the ceramic plates of which the bottom glue is not completely cured. In this embodiment, the wavelength of the ultraviolet light is 200-400 nm, and the power of the ultraviolet light is 1-10 KW.
In one implementation manner, the ceramic plates subjected to the first curing treatment are subjected to a second curing treatment, specifically, the ceramic plates subjected to the first curing treatment are stacked and placed still.
Because the surface of the ceramic plate after being pasted with the net is solidified after the first solidification treatment, the ceramic plate can not be adhered, but the primer between the ceramic plate after being pasted with the net and the gridding cloth is not added with various expensive metal compounds (such as tungsten boride, barium sulfate, magnesium silicide) and other components, the inside of the primer is not quickly solidified, further solidification is needed, in order to ensure that the primer is solidified more thoroughly, the ceramic plates after being pasted with the surface of the net ceramic plate can be stacked and placed, thus, the ceramic plates are not required to be placed at intervals, a brick storage frame is not required to be specially arranged, the occupied space and equipment investment are saved, the ceramic plates are waited for natural solidification and airing in a standing mode, the primer has sufficient time for natural solidification, the solidification process is the process that the primer exerts the bonding effect, and finally, the ceramic plates can be firmly bonded with the gridding cloth, not only the toughness of the ceramic plate for pasting the net is increased, but also an additional production line is not needed, the capital investment is saved, and the continuous production of the automatic pasting net is realized in the real sense.
In summary, the invention discloses a binder formula and a ceramic plate net pasting method, wherein the ceramic plate net pasting method comprises the following steps: obtaining a ceramic plate formed by firing; performing an adhesive coating process on the back surface of the ceramic plate based on the adhesive formula, and attaching a mesh cloth to the back surface of the ceramic plate after the adhesive coating process; and carrying out primary curing treatment on the ceramic plate adhered with the grid cloth, and then carrying out secondary curing treatment on the ceramic plate subjected to the primary curing treatment to obtain a finished product of the net-adhered ceramic plate. According to the invention, the ceramic plate and the grid cloth are subjected to bonding coating treatment based on the binder formula and then are subjected to primary curing, so that the surface of the ceramic plate can be dried by fingers, and the ceramic plate and the grid cloth can be efficiently bonded without increasing extra production cost.
