Problems solved by technology

[0002] The existing boards used to make sanitary ware are monotonous in color, without color changes, and are the same
In addition, there are also plastic sheets that use a synthetic laminate structure to make a variety of patterns, but they must be bonded in multiple layers. Its multi-layer bonding structure includes ①transparent surface layer, ②adhesive layer, ③patterned film layer, ④reinforcing agent layer, ⑤ bottom layer, in the production process, its products are prone to sags, and over time, the adhesive layers will easily fall off due to the aging of the adhesive; in addition, because it is a multi-layer adhesive structure, it is inevitable There are tiny air bubbles that are not easy to be found between the layers in the bonding process. If this board is used in the future, the air bubbles will expand and become larger during the heating and forming process.
In this way, it will not only affect the product quality, but even cause waste products; at the same time, the production process is complicated, the product quality is unstable, the production cost is high, and the investment in production equipment is increased, which will have a certain impact on the interests of enterprises and consumers.

Embodiment 1

[0011] A method for manufacturing a sanitary ware shell compounded with a decorative pattern layer. First, a mixed ink is prepared, and the mixed ink is mixed according to the following chemical components (weight percentage):

[0012] PVC resin powder: 5%; dispersant (polyether modified silicone): 10%;

[0013] Colorant: 5%; Solvent (xylene): 80%.

[0014] The mixed ink adjusted above is directly printed on one side of the transparent polymethyl methacrylate plate 1 with a conventional screen printing process or an inkjet process, see figure 1 shown, and then heated to 110°C and kept warm for 15 minutes to become a sanitary ware shell plate compounded with patterned pattern layer 2, and then put it on the required sanitary ware mold prepared in advance, printed with patterned patterns One side faces the front of the mould, and it is formed by sealing and evacuating the molding method. After natural cooling or blowing cooling, it becomes a sanitary ware shell with patterned l...

Embodiment 2

[0017] The chemical composition (percentage by weight) of mixed ink is:

[0018] PVC resin powder 17%; Dispersant (polyether modified silicone) 15%;

[0019] Colorant 18%; solvent (cyclohexanone) 50%.

[0020] The heating temperature in the thermoforming process is 150° C., the holding time is 8 minutes, and the rest of the process methods are the same as in Example 1.

Embodiment 3

[0022] The chemical composition (percentage by weight) of mixed ink is:

[0023] PVC resin powder 30%; dispersant (polyether modified silicone) 2%;

[0024] Colorant 40%; solvent (butyl acetate) 28%.

[0025] The heating temperature in the thermoforming process is 210° C., the holding time is 2 minutes, and the rest of the process is the same as in Example 1.

Abstract

The invention is a shell producing method for bathing equipment compounded with pattern layer. The invention uses transparent copolyester board as base body, produces the mixed printing ink, the chemical proportion is: PVC resin powder 5-30%; disperser 2-15%; color material 5-40%; solvent 28-80%, the invention uses the normal silk net printing craft or painting craft to print the ink onto one face of the base body and forms various patterns. It is placed into the mould after it has been heated and temperature preserved, the pattern surface opposites to the facade of the mould, and uses sealed extraction method to form, and gets the product after cooling it.

Description

technical field [0001] The invention relates to the technical field of sanitary ware, in particular to a method for manufacturing a sanitary ware shell compounded with a pattern layer. Background technique [0002] The color and luster of the existing boards used for manufacturing sanitary ware is monotonous, and there is no change in design and color, and they are stereotyped. In addition, there are also plastic sheets that use a synthetic laminate structure to make a variety of patterns, but they must be bonded in multiple layers. Its multi-layer bonding structure includes ①transparent surface layer, ②adhesive layer, ③patterned film layer, ④reinforcing agent layer, ⑤ bottom layer, in the production process, its products are prone to sags, and over time, the adhesive layers will easily fall off due to the aging of the adhesive; in addition, because it is a multi-layer adhesive structure, it is inevitable It appears that there are tiny air bubbles that are not easy to be fo...
