Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, the present invention provides an SMC product, which includes: an SMC matrix 1; the composite layer 2 is arranged on the SMC substrate; the sand blasting layer 3 is arranged on the composite layer; the pattern layer 4 is arranged on the sand blasting layer 3; and a nanoceramic layer 5 disposed on the pattern layer 4.

The utility model changes the structure of the prior SMC product; the nano ceramic layer 5 is arranged on the pattern layer 4, and the nano ceramic layer 5 has good weather resistance, excellent gloss, good adhesive force, stain resistance and scratch resistance; the weather resistance of the SMC product is greatly improved, and the service time of the pattern layer is greatly prolonged; meanwhile, the coating has the characteristics of high surface wear resistance, scratch resistance, water resistance and mildew resistance.

In order to improve the adhesion of the printed pattern, the traditional SMC product is often sprayed with a primer layer on the surface of the SMC product and then sprayed with a decorative pattern on the primer layer; the primer coating has high cost, is easily polluted by external oil stains and dust, and cannot ensure the decorative effect.

For this reason, in this example, the primer layer of the SMC article was removed. However, in order to overcome the defect that the adhesive force of the pattern layer is reduced after the primer layer is removed, the composite layer 2 is arranged on the SMC surface, and the composite layer 2 effectively improves the bonding property of the pattern layer 4 and the SMC matrix, so that the adhesive force of the pattern layer 4 is stronger, and the service life is longer. The composite layer 2 can be made by hot-press molding; or spraying the composite layer raw material on the surface of an SMC mould when the SMC matrix is molded, and synchronously hot-pressing and molding the SMC matrix 1 to obtain the composite material.

In this embodiment, the composite layer 2 is selected from a polypropylene layer, a polyvinyl chloride layer, a polyvinyl alcohol layer or a polyurethane layer. These polymer resin layers not only have good adhesion but also can be easily thermoformed to the surface of the SMC substrate 1.

After the SMC matrix 1 is provided with the composite layer 2 and before the pattern layer 4 is prepared, in order to remove oil stains on the surface of the SMC matrix and further improve the adhesive force of the pattern layer 4, carrying out sand blasting operation on the SMC matrix 1 to prepare a sand blasting layer 3; the sand blasting layer 3 has proper roughness, and the adhesive force of the pattern layer 4 and the SMC matrix 1 is effectively improved.

In the present embodiment, the thickness of the pattern layer is less than 0.5 mm; the pattern layer 4 is manufactured by a spray coating process. Specifically, the SMC matrix can be subjected to spray painting according to different decoration requirements. The spraying process effectively improves the decorativeness of the SMC product.

In the embodiment, the nano ceramic layer is made of a nano inorganic oxide resin which is colorless or light yellow transparent liquid and has good weather resistance, stain resistance, water resistance and scratch resistance, so that the pattern layer is effectively protected; in this embodiment, the nano-ceramic layer 5 is prepared by a spraying process, specifically: mixing the nano inorganic oxide resin material for spraying with a curing agent according to a given ratio; mixing and spraying; and heating and curing after spraying to obtain the SMC product finished product. During spraying, a spray gun head of the spraying equipment and a sprayed SMC product should keep the principle of uniform speed and uniform quantity; during curing, the curing conditions are as follows: 15min at 150 ℃; excessive temperatures tend to cause cleavage faults (meaning the cleavage between the glass fibers and the unsaturated polyester resin material) in the SMC article substrate. Furthermore, in the embodiment, the thickness of the nano ceramic layer is 5 to 7 μm, and the nano ceramic resin material is easily cracked due to an excessive thickness, thereby affecting the function of the nano ceramic resin material.

Correspondingly, referring to fig. 3, in order to further enhance the decoration function of the SMC of the present invention, in another embodiment of the present invention, concave-convex lines are provided on the SMC substrate 1, so that the SMC product has a simulated relief effect. There is no particular limitation on the specific shape of the uneven pattern. Preferably, natural stone grain is used.

Accordingly, in this embodiment, in order to enhance the decoration function, the pattern layer 4 may select corresponding patterns according to different texture effects. The spray painting pattern and the simulation relief effect on the surface of the SMC product are integrated into a whole, and a vivid surface effect is generated.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
