Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. The examples, in which specific conditions are not specified, were conducted under conventional conditions or conditions recommended by the manufacturer. The reagents or instruments used are not indicated by the manufacturer, and are all conventional products available commercially.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to specific examples.
The invention provides a lacquer painting manufacturing process with gold wires embedded in the surface, which mainly comprises the following steps:
mixing raw lacquer, vermiculite and chlorite to prepare primer; coating the primer on the base plate, drying, and attaching the prefabricated pattern to the base plate to obtain a prefabricated product I; according to the prefabricated pattern, grooving at the corresponding position of the prefabricated pattern on the prefabricated product I, after filling the glue in the groove, embedding the gold wire in the groove, and grinding the gold wire protruding out of the base plate to obtain a prefabricated product II; coating pigment on the position of the non-gold wire of the second prefabricated product, drying to obtain a semi-finished product, and coating primer for 2-3 times on the semi-finished product to obtain a third prefabricated product; and polishing the primer of the third prefabricated product to obtain the lacquer painting.
Specifically, raw lacquer, vermiculite and chlorite are mixed uniformly to prepare the primer. The raw lacquer, also called as Chinese lacquer, lacquer and earth lacquer, is a milky pure natural liquid coating obtained from lacquer trees, gradually turns brown after contacting with air, has the characteristics of corrosion resistance, wear resistance, acid resistance, solvent resistance, heat resistance, water resistance and good insulativity, and has rich luster in appearance, so that the raw lacquer is used as a main raw material of the primer.
Vermiculite: the vermiculite takes silicon dioxide as a main chemical component, simultaneously contains chemical components such as aluminum oxide, ferric oxide, magnesium oxide and the like, has the characteristics of good heat preservation, heat insulation, fire prevention and the like, and has high use value. When the primer is mixed with raw lacquer to prepare the primer, the primer has the advantages of high temperature resistance, fire resistance, environmental protection, heat insulation, sound insulation, harmlessness and the like, so that the primer has longer storage time. In addition, after the primer is used, due to the viscosity of raw lacquer and the air permeability of vermiculite, the primer has the advantages of being not easy to fall off, not broken, not absorbing moisture and the like, and has a good using effect.
Chlorite: chlorite is a generic term for a family of layered structure silicate minerals of monoclinic, triclinic or orthorhombic (orthorhombic) crystal system. The chlorite has fine and smooth texture, so when the chlorite is used as primer, the primer has fine texture and good effect. In addition, the chlorite is hard and has hardness of 2.5-2.8, so that the primer has high filming effect and high use value. Moreover, the primer with harder texture can not be mixed with the pigment, so that the phenomenon of mixing when the primer is not dried completely is avoided, and the fault tolerance rate is higher.
In conclusion, the base paint prepared by mixing raw lacquer serving as a main material and vermiculite and chlorite serving as auxiliary materials has the advantages of corrosion resistance, wear resistance, acid resistance, solvent resistance, heat resistance, water resistance, sound insulation, insulation and the like, has the characteristics of difficult falling, no breakage and no moisture absorption, is hard in texture, can effectively enhance the fault tolerance rate of the preparation process, and is suitable for industrial production.
It is to be noted here that the chlorite can also be further processed and then mixed. Specifically, the chlorite is calcined in a segmented mode at the temperature of 800-1200 ℃ to prepare the expanded chlorite, so that the performance of the chlorite is enhanced, and the using effect is improved.
According to the invention, raw lacquer, vermiculite and chlorite are stirred for 10min-15min under the condition of 200rpm-300rpm, so that the raw materials are uniformly mixed, and then are homogenized under the condition of 0.3MPa-0.5MPa for 3min-5min, so that the vermiculite and chlorite can be more uniformly distributed in the raw lacquer, and the primer has uniform texture and superior quality.
In the invention, the mass ratio of the raw lacquer to the vermiculite to the chlorite is (7-9) to (2-3) to 1. The raw lacquer is used as a main raw material, the vermiculite is used as a main breathable raw material, the raw lacquer can be uniformly distributed in the raw lacquer, and the chlorite is hard in texture, so that the addition proportion is large, and the quality of the lacquer painting is easily influenced. Therefore, the invention can avoid the quality problem caused by a large amount of vermiculite and chlorite while ensuring the beneficial effect by adding the proportion, has scientific and reasonable proportion and is suitable for industrial production.
After the primer is manufactured, the primer can be coated on the base plate, and drawing is carried out after the primer is dried, so that a first prefabricated product is obtained.
In the invention, the primer can be coated on the bottom plate in a roller coating, dip coating or pouring coating mode, so that the coating effect is uniform, and the conditions of partial thin coating, partial thick coating or exposed coating are avoided.
After coating, inspection can be carried out, and if coating leakage occurs, the residual product can be removed and manufactured again.
The finished product which is coated successfully can be dried under the condition of 35-40 ℃, so that the primer can be dried under the condition of low temperature, and the manufacturing period of the lacquer painting can be shortened. When the temperature is higher, the primer is easy to soften, so that the primer formed by coating is damaged, and the painting process is influenced. And when the temperature is lower, the drying time is longer. Therefore, under the temperature condition, the preparation period can be effectively shortened, and particularly, the drying time can be shortened by 2-4 times, so that the effect is obvious.
It is also noted that in the present invention, the base plate is polished under a pressure of 0.3MPa to 0.35MPa before the primer is applied. Because the bottom plate can select for use the bottom plate of materials such as wooden board, timber synthetic board, plastic board and stone board, consequently, the phenomenon of unevenness easily appears in its surface, and direct coating priming paint not only easily appears the phenomenon of unevenness, still easily makes the priming paint crack appear, and the effect is not good. Therefore, before the base plate is coated with the primer, the painting making surface can be polished, so that the surface of the painting making surface is flat and smooth, and the expected painting making effect is achieved.
In the invention, the drawing mode can be silk-screen printing or scraping printing, the outline of the painting or the painting itself is printed on the bottom plate, and the prefabricated product I is prepared after the printing traces are dried.
Then, a groove is formed in the position of the first prefabricated product where the gold wire needs to be embedded, and after the groove is filled with the glue, the gold wire is embedded into the groove. It should be noted here that the depth and width of the groove are matched with the gold wire, so as to avoid the problems of large groove width, poor picture quality, deep groove depth, easy burying of the gold wire in the groove and loss of the value of embedding the gold wire.
In order to ensure that the embedding effect between the gold wire and the bottom plate is better and the texture of the painting is better, the glue agent can be filled at the bottom of the groove, so that the tightness between the gold wire and the bottom plate can be enhanced, and the groove width gap can be reduced, so that the outline of the painting is better in appearance and better in manufacturing effect.
In the invention, the glue is prepared by mixing kaolin, polypropylene and epoxy resin. Wherein, the kaolin is white and fine clay, and has good plasticity and fire resistance. Moreover, the kaolin has stronger binding effect with water and other raw materials and better binding effect.
The polypropylene is a polymer formed by the addition polymerization of propylene, is transparent and light in appearance, and has chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties, good wear resistance and the like. And the polypropylene can better mix other raw materials, so that the physical and chemical properties of the adhesive are improved, the viscosity can be enhanced, and the using effect is better.
The epoxy resin is a generic name of a polymer containing more than two epoxy groups in a molecule, and is a polycondensation product of epichlorohydrin and bisphenol A or polyol. The epoxy resin has good chemical resistance and bonding strength, and simultaneously has good mechanical property and electrical insulation property. Therefore, when the epoxy resin is used as the raw material of the adhesive, the chemical resistance, the high-temperature resistance and the electrical insulation performance of the adhesive can be enhanced, the expected adhesive effect is achieved, meanwhile, the adhesive can be well and tightly connected with the wall of the slot, and the using effect is good.
In conclusion, the adhesive adopted in the invention takes polypropylene as a main raw material, and the kaolin and the epoxy resin are tightly bonded, so that the characteristic of poor weather resistance of the epoxy resin can be effectively improved, and the physical and chemical properties of the polypropylene can be further enhanced. Meanwhile, due to the existence of the kaolin, the glue positioned between the gold wire and the slot wall is easy to color after the slot is filled with the glue, so that the quality of the painting is not easily influenced, and the use value is higher.
In some embodiments of the invention, the mass ratio of the kaolin to the polypropylene to the epoxy resin is 1 (5-6) to (3-6). Under this proportion, the quality proportion scientific and reasonable of kaolin, polypropylene and epoxy, can be under the condition of guaranteeing viscosity, have the characteristics of easily coloring and easily polishing, the result of use is better.
In some embodiments of the present invention, after a gold wire is embedded in a preform, the preform is cured at 35 ℃ to 45 ℃ and then polished. The paint is solidified under the condition of low temperature, so that the fixing effect of the gold wire is better, the condition that the gold wire falls or becomes loose in the using process of the paint picture is avoided, the primer can be prevented from being damaged under the condition of high temperature, and the expected effect is better.
In addition, ultraviolet rays and infrared rays can be used for curing in a low-temperature curing room, and air drying and other modes can be compounded, so that the expected effect is achieved, and the manufacturing period can be shortened.
After the curing is finished, the gold wire and the adhesive can be exposed out of the flat plate, so that the position of the gold wire can be polished, and the picture is in a flat state.
In some embodiments of the invention, the pressure of the sanding is between 0.15MPa and 0.25 MPa. Under the polishing pressure, the cured adhesive and the gold wire can be polished flat, so that the primer can not be polished off, and the effect is better. When the polishing pressure is higher, the primer is easily ground off to expose the bottom plate, which is not beneficial to coating pigment, and when the polishing pressure is lower, the polishing time of the solidified adhesive and the gold wire is longer, and the time cost of painting is higher.
And after finishing polishing the gold wires and the adhesive, obtaining a second prefabricated product, and placing the second prefabricated product on a conveyor belt and coating pigment at the corresponding position. After the pigment is coated, the second prefabricated product has a painting pattern, so that the manufacturing effect is achieved.
It should be noted that in the present invention, the drawing sample can be input by scanning, modeling, etc., so that the drawing sample of the lacquer painting is diversified and meets the requirement of the consumer.
In some embodiments of the invention, the pigment is applied at a thickness of 0.05mm to 0.2 mm. When the thickness of pigment is as above, polish the lacquer painting, can avoid pigment to drop and expose the priming paint, lose the meaning of lacquer painting. When the thickness of the pigment is thick, the pigment is easy to crack and fall off from the bottom plate in a blocking manner, so that the quality of the lacquer painting is influenced.
