Abstract
The invention discloses a processing method of a decorative composite board, which comprises the following steps: SMC preparation: mixing polyester resin, vinyl ester, epoxy resin, phenolic resin and an additive to form resin slurry, and coating the resin slurry on a bottom film carrier; applying glass fibers and carbon fibers onto an upper surface of the resin slurry on the membrane carrier; applying a layer of resin paste on the mixed reinforcing fibers, and applying a top film on the uppermost layer of resin paste; s2: heating the composite die; s3: preparing a composite sheet by placing a first SMC sheet in a lower mold, placing a foamed layer on the first SMC sheet, placing a second SMC sheet on the foamed layer, applying a layer of granular material to an upper mold and then placing the molds together under pressure to compress the components and cure the SMCs; s4: when the molding process is complete, the resulting composite panel is removed from the mold and the solidified SMC material is removed from the surface of the composite panel by a sand blasting process, exposing sand particles to the surface of the composite panel.
Description
Technical Field
The invention relates to a processing method of a decorative composite board.
Background
Panels and other elements used in buildings are traditionally made of natural materials. For example, doors and panels for buildings and furniture have traditionally been made of wood. Other walls and panels have been made of either bricks or stones. However, the trend in building elements and other products traditionally using natural products is to be made of "non-natural" or synthetic products, such as plastic materials. Such modern materials have many chemical, physical and cost advantages over traditional materials. Foamed resin laminates comprising a foamed resin layer and a skin are increasingly used in the building, decoration and furniture industries because of the wide range of useful properties that can be achieved. However, such modern materials have a different appearance than traditional materials, which detracts from their attractiveness for certain applications. Plastic materials with simulated wood grain and wood grain are available and attempt to produce panels and doors having an appearance that approximates that of traditional solid wood. However, it is also desirable to provide panels and other products that simulate other types of surfaces, such as stone.
Disclosure of Invention
The invention aims to overcome the defects of the technology, thereby providing a processing method of a decorative composite board, which can simulate a composite board of a natural decorative material.
The technical scheme adopted by the invention is as follows: the processing method of the decorative composite board comprises the following steps:
s1: SMC preparation: polyester resin, vinyl ester, epoxy resin, phenolic resin and additive are mixed according to the weight ratio of 65: 8: 6: 6: 15 mixing to form resin slurry, and coating the resin slurry on the bottom film carrier; mixing glass fiber and carbon fiber in a ratio of 2: 1 cutting the length of the mixed reinforcing fiber to 3-5mm after mixing, and then applying the mixed reinforcing fiber to the upper surface of the resin slurry on the film carrier; applying a further layer of resin mastic over the mixed reinforcing fibres, applying a top film over the uppermost layer of resin mastic, then forming sheet moulding plastics using roller compaction between the film carriers, the thickness of the sheet moulding plastics being controlled to 4mm, rolling the material onto the rollers and holding at a controlled temperature of 23 to 27 ℃ for at least 3 days;
s2: heating the composite die, namely heating the upper die and the lower die to 130-140 ℃;
s3: preparing a composite board, namely placing a first SMC plate in a lower die, placing a honeycomb cotton layer on the first SMC plate, placing a second SMC plate on the honeycomb cotton layer, applying a layer of granular material to an upper die, placing a plurality of cobbles on the second SMC plate, then placing the dies together under pressure to compress the components and solidify the SMC, and controlling the pressure to be 10-20 MPa to obtain the composite board;
s4: when the molding process is complete, the resulting composite panel is removed from the mold and the solidified SMC material is removed from the surface of the composite panel by a sand blasting process, exposing sand particles to the surface of the composite panel.
The further improvement is that: in step S1, the additives include inert fillers, pigments, stabilizers, inhibitors, mold release agents, catalysts, and thickeners.
The further improvement is that: in step S3, the layered granular material includes sand particles and metal particles.
The further improvement is that: in step S3, a layer of granular material is applied into the cavity of the upper die by an adhesive.
By adopting the technical scheme, the invention has the beneficial effects that: guarantee the intensity of composite sheet through both sides SMC board, through setting up the cotton layer of honeycomb for the whole good syllable-dividing of possessing of composite sheet, fire-retardant, the heat preservation effect, the outside sets up layer granular material and forms similar natural embellishment in addition.
