Abstract
Description
Technical Field
[0001] The present invention relates to a processing technology of a bathtub, specifically to a processing technology of an acrylic spliced bathtub without FRP reinforcement. Background Art
[0002] Currently, basically all acrylic bathtubs use resin fiber reinforcement, which is completed by spraying resin fiber during the production of acrylic bathtubs. This production process causes a relatively poor working environment, with strong odors and a lot of dust during the production process. In order to improve the production environment and shorten the production process, environmentally friendly production is proposed. At the same time, to improve the grade of acrylic spliced bathtubs, research and development of acrylic spliced bathtubs without FRP reinforcement is carried out. Summary of the Invention
[0003] Aiming at the problems in the prior art, the present invention provides a processing technology of an acrylic plate spliced bathtub to solve the problems that the bathtub body and the back of the outer cover adopt FRP spraying in the prior art, which causes a relatively poor working environment, with strong odors and a lot of dust during the production process.
[0004] In order to achieve the above object, the present invention provides the following technical solutions: A processing technology of an acrylic spliced bathtub without FRP reinforcement, characterized by comprising the following steps: A. According to the design drawings of the bathtub body and the outer cover, respectively process and manufacture the corresponding forming molds; B. Bathtub body forming: Use acrylic plates with a thickness of 10 mm - 12 mm, the baking temperature of the plates is 180°C - 220°C, and it needs to be baked for 25 - 32 min; then use the bathtub body forming mold for thermoforming; C. Outer cover forming: Use acrylic plates with a thickness of 6 - 8 mm, the baking temperature of the plates is 180°C - 220°C, and it needs to be baked for 8 - 20 min, then use the outer cover forming mold for thermoforming; D. Make a flat overflow part forming mold that fits the outside of the bathtub body, use acrylic plates with a thickness of 3 mm, and use the flat overflow part forming mold for thermoforming; E. Do not perform resin fiber reinforcement on the bathtub body, the outer cover, and the overflow part, and cut these three; F. Bond the overflow part and the bathtub body with acrylic glue; G. Splice, grind, and polish the bathtub body and the outer cover with acrylic glue; H. Install a support on the bottom of the bathtub body.
[0005] Preferably, in step B, an acrylic sheet with a thickness of 10 mm - 12 mm is used, the baking temperature of the sheet is 200 °C, and it needs to be baked for 28 - 30 minutes; then it is vacuum formed using the bathtub body forming mold.
[0006] Preferably, in step C, the baking temperature of the sheet is 200 °C.
[0007] The beneficial effects of the present invention are as follows: After the original acrylic bathtub is vacuum formed, it needs to be strengthened by FRP spraying. Now, the FRP spraying is cancelled, and the finished product is directly completed by splicing after vacuum forming with thick sheets. This not only reduces the production process but also improves the production environment, effectively improving labor productivity and realizing environmental protection production. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Figure 1 is the process flow chart of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0011] The technical solutions of the present invention will be described below in conjunction with the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments; and the structures shown in the drawings are only schematic and do not represent real objects. It should be noted that based on these embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.
[0012] It should be noted that in this article, the term "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements but also includes other elements not explicitly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of another identical or equivalent element in the process, method, article or device including the said element.
[0013] The terms "upper", "lower", "inner", "outer", etc. do not constitute an absolute spatial relationship limitation, but only a concept of relative position. This is understandable to those skilled in the art.
[0014] The processing technology of an acrylic splicing bathtub without FRP reinforcement includes the following steps: 1. According to the design drawings of the bathtub body and the outer cover, process and manufacture the bathtub body forming mold and the outer cover forming mold respectively; 2. Bathtub body forming: Use acrylic sheets with a thickness of 10 mm - 12 mm. The baking temperature of the sheets is 200 °C and it needs to be baked for 28 - 30 min. Then, use the bathtub body forming mold for thermoforming to obtain the bathtub body 6 made of acrylic. 3. Outer cover forming: Use colored transparent acrylic sheets with a thickness of 6 - 8 mm. The baking temperature of the sheets is 200 °C and it needs to be baked for 8 - 20 min. Then, use the outer cover forming mold for thermoforming to obtain the outer cover 2 made of acrylic. 4. Make a flat overflow part forming mold that fits the outside of the bathtub body 6. Use acrylic sheets with a thickness of 3 mm and use the flat overflow part forming mold for thermoforming to obtain the overflow part 3. 5. Do not perform resin fiber reinforcement on the bathtub body 6, outer cover 2, and overflow part 3. Directly cut and shape these three components, cut the waste edges according to the product quality standards, and drill overflow holes 1 and drain holes 7 at the corresponding positions. 6. First, bond the overflow part 3 to the side of the bathtub body 6 along the overflow hole 1 and drain hole 7 with acrylic glue to serve as the overflow channel for drainage. 7. Use acrylic glue to splice 5 between the bathtub body 6 and the outer cover 2. After splicing 5, perform grinding treatment, and finally perform surface polishing. 8. Bond four plastic feet 4 to the bottom of the acrylic bathtub body to increase the support force of the bathtub. The present invention is not limited to the above specific embodiments. Those of ordinary skill in the art can implement the present invention in many other specific embodiments according to the embodiments and the disclosed content of the drawings. Therefore, any design that adopts the design structure and concept of the present invention and makes some simple transformations or modifications falls within the protection scope of the present invention.
