Description

SMC color composite wall board

Technical Field

The utility model belongs to the technical field of the wallboard technique and specifically relates to indicate a colored composite wall panel of SMC.

Background

The SMC wallboard is divided into two types according to the research and development time, one type is the domestic earliest SMC wallboard with stone grains/skin grains, and the obvious points are that the wallboard is rough, has no luster and is difficult to clean hygienically, and the wallboard is basically used in the integral bathroom sold at low price in the market at present. The other is SMC paper molded wallboard, which is the wallboard mainly adopted by the national unit bath manufacturers who are engaged in the hand-pasted glass fiber reinforced plastic wallboard manufacturing and lack the unit bath system manufacturing technology.

At present, the main problem that exists of SMC mould pressing decorative paper wallboard that whole bathroom adopted: 1. the color wallboard is manufactured by adding color decorative paper and a die pressing process, and the color decorative paper is solidified in the surface layer of the wallboard, so that the color decorative paper becomes mildewed after a bathroom is used for several years, and the defect that the surface layer of the die pressing wallboard becomes mildewed is caused, thereby influencing the use; 2. although the SMC mould pressing color wallboard solves the problem of individuation of the surface color of the SMC mould pressing wallboard, the hollow sense and the plastic sense of the wallboard still exist because the structure of the wallboard is not changed. Therefore, there is a need to develop a solution to the above problems.

SUMMERY OF THE UTILITY MODEL

In view of the above, the present invention is directed to the deficiency of the prior art, and the main objective of the present invention is to provide a SMC color composite wallboard, which can effectively solve the defect of the existing SMC wallboard that the cavity has no texture.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

an SMC colorful composite wallboard comprises an SMC mould pressing base layer, a back plate, a transfer printing layer and a nano coating; the back plate is arranged on the back surface of the SMC mould pressing base layer, an accommodating cavity is formed between the back plate and the SMC mould pressing base layer, and a filling heat-insulating layer is filled in the accommodating cavity; the transfer printing layer covers the front side of the SMC mould pressing base layer; the nano coating is covered on the surface of the transfer printing layer.

Preferably, the back of the SMC mould pressing base layer is integrally formed with reinforcing ribs with different heights, one part of short reinforcing ribs are embedded in the filling heat-insulating layer, one part of high reinforcing ribs surround the accommodating cavity, and the other part of reinforcing ribs are arranged at the edge of the SMC mould pressing base layer.

Preferably, the SMC molding substrate has mounting sites formed on the edges thereof.

Preferably, the back plate and the reinforcing ribs with reserved heights form an accommodating cavity, and the back plate is made of galvanized steel plate materials.

Preferably, the filling and insulating layer is made of polyurethane foam or a honeycomb plate.

Compared with the prior art, the utility model obvious advantage and beneficial effect have, particularly, can know by above-mentioned technical scheme:

the SMC mould pressing base layer is formed through mould pressing, and the combination of thermal transfer printing and nanotechnology is carried out in a matching way, so that the surface color of the wallboard is personalized, the glossiness and the stability of the surface color are fundamentally changed, the defect that the decorative paper is mildewed is avoided because a decorative paper process is not adopted, and meanwhile, a filling heat-insulating layer is filled in a containing cavity formed between the SMC mould pressing base layer and the back plate so as to fill the back of the mould pressing wallboard, and the defect that the existing SMC wallboard is hollow and has no texture is thoroughly solved.

To more clearly illustrate the structural features and functions of the present invention, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments:

Detailed Description

Referring to fig. 1 to 4, the detailed structure of the preferred embodiment of the present invention is shown, which includes an SMC molding substrate 10, a back plate 20, a transfer printing layer 30 and a nano-coating layer 40.

The back plate 20 is arranged on the back surface of the SMC molded base layer 10, an accommodating cavity 101 is formed between the back plate 20 and the SMC molded base layer 10, and the accommodating cavity 101 is filled with the filling insulation layer 50; in this embodiment, the back integrated into one piece of SMC mould pressing basic unit 10 has the strengthening rib 11 of difference in height, and partly short strengthening rib 11 buries in filling heat preservation 50, and holding chamber 101 is enclosed into to partly high strengthening rib 11, and another part strengthening rib 11 is at SMC mould pressing basic unit 10 edge, and the thickness of a plurality of strengthening ribs 11 is not of uniform size, can set up as required, and the setting of strengthening rib 11 makes the whole structure that increases of product whole formation, and the follow-up foaming processing of being convenient for combines with backplate 20 to form a holistic holding chamber 101, and, the edge of SMC mould pressing basic unit 10 is formed with installation position 12, zonulae occludens between wallboard and the wallboard when being convenient for install the wallboard in the future, and the wallboard installation is simple like this, backplate 20 is materials such as galvanized steel sheet, it is polyurethane foaming material, honeycomb board material or other filling materials to fill heat preservation 50.
