The present invention discloses a manufacturing method of a color decorative plate for an integral bathroom. Firstly, a decorative fiber cloth is immersed and a surfacing material is prepared, wherein the steps include: adding various auxiliaries to an unsaturated polyester resin; uniformly mixing to form a resin paste, wherein the auxiliaries contain an initiator, a mold discharging agent, an accelerator, a coupling agent, a crosslinking monomer and cinnamene; uniformly coating the above resin paste on the decorative fiber cloth; precuring and drying at 105 C. to 130 C. to produce the surfacing material; then compression moulding; feeding a sheet molding compound (SMC) into a mould; and laying the surfacing material on the SMC in the mould for integral compression moulding. In the compression moulding process, a mold cavity is at an upper part and a mold core is at a lower part to prevent decorative patterns from deforming because the decorative fiber cloth is stretched due to the flow of the SMC and to avoid wrinkling the decorative fiber cloth. The SMC is used as a structural layer, and the surfacing material is attached to a surface of the structural layer. The patterns on the surface of a finished product have high clarity and brightness.

Co-cured urethane and vinyl ester, epoxy, or unsaturated polyester gel coats having improved toughness and flexibility compared with conventional polyester gel coats are disclosed. The gel coats, which have 10-50 wt. % urethane content, adhere well to structural layers and can be used in a traditional in-mold process. Co-cured elastomeric coatings comprising from 50 to 95 wt. % of a urethane component and an unsaturated polyester, epoxy, or vinyl ester are also disclosed. Unlike conventional urethane coatings, the elastomeric coatings adhere well to structural layers and can be used in a traditional in-mold process. Castings or structural layers comprising a reinforced thermoset of co-cured urethane and vinyl ester, epoxy, or unsaturated polyester components, including 10-95 wt. % of the urethane component, are also described. The invention includes in-mold processes for making laminates that utilize the gel coats, elastomeric coatings, and/or structural layers. The in-mold process gives flexible, durable, urethane-containing laminates having good interlayer adhesion.

A system for controlling a fiber orientation and/or a density of fibers in a mold comprises at least one nozzle configured to define a location at which gas is withdrawn from the mold. A displacement mechanism is configured to effect a relative displacement between the at least one nozzle and the mold.

The phosphorescent chip (II) includes about 8 wt % to about 15 wt % of an unsaturated polyester resin (A), about 85 wt % to about 92 wt % of a silica-containing compound (B) based on a total amount of the unsaturated polyester resin (A) and the silica-containing compound (B) of the phosphorescent chip (II), and further includes about 2 parts by weight to about 10 parts by weight of a phosphorescent pigment (D) based on about 100 parts by weight of the unsaturated polyester resin (A). The silica-containing compound (B) includes about 20 wt % to about 30 wt % of a silica powder (b1) based on a total amount of the phosphorescent chip (II).

A composite core material and methods for making same are disclosed herein. The composite core material comprises mineral filler discontinuous portions disposed in a continuous encapsulating resin. Further, the method for forming a composite core material comprises the steps of forming a mixture comprising mineral filler, an encapsulating prepolymer, and a polymerization catalyst; disposing the mixture onto a moving belt; and polymerizing said encapsulating prepolymer to form a composite core material comprising mineral filler discontinuous portions disposed in a continuous encapsulating resin.

A method of insert molding comprises placing in a first mold a curable rubber composition comprising a reactive species; placing on a surface of the rubber composition a first thermoplastic material in a film or layer comprising a group reactive with the reactive species of the rubber composition; curing the rubber composition in the mold to form a first molded article of cured rubber having a first thermoplastic material layer covalently bonded through reactive of the reactive species and the group; placing the first molded article as an insert into a second mold, the cured rubber contacting an inside surface of the second mold and the thermoplastic layer facing into the second mold cavity; closing the second mold and injecting into the second mold a second thermoplastic material that to form a second molded article comprising the first molded article thermally welded and/or covalently bonded to the second thermoplastic material.
