Description
Technical Field
The invention relates to the technical field of fireplace production, in particular to a production process of a high imitation marble carving fireplace rack.
Background
The fireplace is used as an ancient stone product and has a very long-term popularity, the basic structure of the fireplace comprises a fireplace rack and a fireplace core, the fireplace rack mainly plays a decoration role, the fireplace core mainly plays a practical role, the fireplace is originally a tool for heating in western countries, along with the development of society, the fireplace is introduced into China, the fireplace mainly plays a decoration role in China, particularly in the south, is used as a decoration ornament of a background wall, has a large domestic market, and can effectively improve the high-end feeling of houses. Since the last 90 years of the last century, the production of fireplaces gradually shifted to China, a great number of fireplaces were purchased from China abroad every year, and the fireplaces are already the production bases of fireplaces, and the materials of fireplace racks are also different, and generally speaking, the fireplaces are mainly divided into marble materials, wood materials, marble-like materials, steel materials, alloy materials, stacked fireplaces and the like.
The marble-imitated material as a substitute of marble is most commonly polyester type which takes unsaturated polyester as a binder and is stirred and mixed with quartz sand, marble, calcite powder and the like for casting and forming, and cement type which takes various kinds of cement as a binder, sand as fine aggregate, crushed marble, granite, industrial waste residue and the like as coarse aggregate and is prepared by burdening, stirring, forming, pressure steam curing, polishing and polishing, commonly called terrazzo; polyester type materials are expensive, cement type materials are low in price, but the existing cement type materials are only suitable for being made into plates, the stability of the materials is poor, and the polyester type materials and the cement type materials have the problem that the polyester type materials are greatly different from real marbles in texture.
Therefore, a material with lower cost and quality closer to marble is needed to meet the market demand.
Disclosure of Invention
In view of the above, the present invention aims to provide a production process of a high imitation marble material carved fireplace rack, which has low production cost, texture closer to marble and high imitation level.
The technical scheme of the invention is as follows: a production process of a high imitation marble carving fireplace rack comprises the following steps: s1: MgCl 2.6H2O is dissolved in water to prepare a magnesium chloride solution, MgO powder is added into the prepared magnesium chloride solution, and the mixture is stirred in a stirrer to obtain uniform slurry; s2: mixing polyacrylic acid emulsion, trimethylolpropane crystals, ethanol, phosphite ester and water to prepare a treating agent, pouring the treating agent into the uniform slurry, stirring, uniformly stirring, standing for 30-45 min, and taking out the slurry to obtain a slurry matrix; s3: pouring the slurry matrix into a mold for molding, curing in air for 12-24 h, and demolding to obtain a fireplace frame blank; s4: carrying out surface polishing treatment on the blank body of the fireplace rack, sending the blank body into a paint room after the surface is smooth, spraying white paint on the surface of the blank body, and drying and curing the blank body; s5: taking the water-soluble polyvinyl alcohol film printed with the marbleized, and carrying out water coating transfer printing on the oven frame blank with the dried and solidified surface to obtain the marble-imitated oven frame with the marbleized surface; s6: and (5) spraying transparent UV paint on the surface of the fireplace rack in S5, and obtaining a finished product after finishing curing and locally polishing.
Furthermore, the Baume degree of the magnesium chloride solution is controlled to be 28-34, and the mass ratio of magnesium oxide to magnesium chloride is 5-6: 1.
Further, the mass ratio of the polyacrylic acid emulsion, the trimethylolpropane crystals, the ethanol, the phosphite ester and the water is as follows: (0.8-1.5): (0.5-0.9): (5-8): (0.2-0.5): (70-100).
Further, the mass ratio of the polyacrylic acid emulsion, the trimethylolpropane crystals, the ethanol, the phosphite ester and the water is as follows: 1: 0.65:6:0.3:90.
Further, the volume ratio of the homogeneous slurry in S1 to the treating agent in S2 is: 1:1.5-2.
Further, glass fibers are added into the slurry matrix obtained in the step S2, stirring is carried out, and then the slurry matrix is sent into a step S3 for molding, wherein the mass ratio of the slurry matrix to the glass fibers is 1: 0.1-0.3.
The production process of the high imitation marble carving fireplace rack provided by the invention is different from the formula of the existing production process of the high imitation marble carving fireplace rack, and firstly, magnesium oxychloride cement is used as a substrate, and a treating agent is used as an auxiliary material, so that the characteristics of good water resistance, wear resistance, similar gray color and luster with the interior of the stone, high temperature resistance, appearance, hand feeling and sound similar to marble are achieved, and the simulation degree is very high. Because the magnesium oxychloride cement structure is heterogeneous porous, there are more gaps and holes inside the structure, the crystallization contact points are more, meet water and connect by dissolution, and the gap becomes the water invasion channel, so polyacrylic emulsion and trimethylolpropane are introduced, polyacrylic emulsion mixes trimethylolpropane and gets into the gap to form the membrane structure, plug up a large amount of gaps, trimethylolpropane adds simultaneously and makes the molecule hydrophobicity increase, the hydrone is difficult to get into inside the membrane, thereby the water resistance has been improved, phosphite ester cooperation ethanol sneaks into aquatic and forms the turbid liquid, participate in and soak in the basement with this and improve stability, and make whole colourity stable. The obtained product has good hand feeling and texture, simultaneously has crisp sound similar to marble, is similar to marble in appearance, hand feeling and sound feeling, achieves high-imitation effect, has the cost of only 1/5 to 1/10 of the cost of marble compared with the cost of marble, has extremely high price and has good market and development prospects.
Detailed Description
The production process of the high imitation marble carving fireplace rack provided by the invention takes the magnesium oxychloride cement as the substrate and is assisted by the treating agent, so that the produced fireplace has the effect of high imitation marble, is similar in hand feeling, appearance and sound feeling, and has the cost far lower than that of marble.
