Abstract
The invention relates the field of building materials, in particular to an imitation stone composite board and a preparation process thereof. The imitation stone composite board sequentially comprises a transparent panel, an EVA (Ethylene Vinyl-Acetate Copolymer) film layer, an epoxy resin layer and a base plate from top to bottom and is prepared by heating at negative pressure. The preparation process comprises the following steps: firstly, performing trimming and thickness calibrating on the base plate as well as performing surface roughening treatment and drying on the inner end face, trimming and drying the transparent panel and performing surface roughening treatment on the inner end face; secondly, performing 3D (three-dimensional scanning) on patterns; thirdly, heating and attaching. Due to the adoption of the structure and the process, the composite board has the advantages of light weight, high strength, high anti-contamination capability, convenience for mounting, high consistency of colors and patterns, wide application range, low cost, high safety and three-dimensional light transmitting effect; the panel can be prevented from being broken and falling off.
Description
Technical field
The present invention relates to building material field, be specifically related to decorative imitated stone composite board and preparation technology.
Background technology
Composite board refers to the sheet material by two kinds or two or more combinations of materials.In fact, for the sheet material with unlike material, the concept of composite board and preparation method are also different.In daily life, often use based on metallic composite panel, wood-plastic composite panel and glass reinforced plastic composite board material.Natural stone material category is many, textured pattern and color various, decorative pattern is inconsistent, arranges in pairs or groups also unreasonable, has had a strong impact on its boundary of works area and decorative effect.And imitative stone composite board is because its simulated effect is good, low price, color and decorative pattern unification, and by demand process, decoration of exterior wall can be applied to gradually in recent years.But the problems such as existing imitative stone composite board is not easy to clean, fineness is not high enough, texture is good not, not wear-resisting, and texture only has plane effect, aesthetic property is poor, and effect is poor.
Summary of the invention
The object of the invention is to provide imitative stone material space pattern composite plate, has anti-strike and chip resistant function, has 3-D effect simultaneously, pattern and color unification.
Imitative stone composite board, from top to bottom comprise transparent panel successively, EVA film layers, epoxy resin layer, base plate, make through heating negative pressure, described transparent panel is pebble plate, the inner face of described pebble plate also sprays and is provided with surface glue, be convenient to gummed, EVA film layers is prevented to be shifted, described EVA film layers is hyaline layer, described EVA film layers has 3D color stone material texture layer by 3D inkjet printing, the thickness of described EVA film layers is 0.1 ~ 1.2 millimeter, the thickness of epoxy resin layer is 0.2 ~ 1.2 millimeter, described base plate is stone slab, described stone slab inner face is provided with the surface course of alligatoring.
Another object of the present invention is to provide the preparation technology of imitative stone composite board: 1, first carry out trimming, fixed thick, inner face surface coarsening process, oven dry to base plate, carries out trimming, oven dry, inner face carry out surperficial glue spraying process to transparent panel, 2, pattern 3D scans: carry out 3D scanning to natural stone texture pattern, after treatment, input computer, by 3D inkjet printing with in the EVA film layers of transparent panel corresponding specification, 3, add thermal-adhering: in dustless space, after surperficial glue spraying process is carried out to transparent panel inner face, after first sticking EVA film layers, stick epoxy resin layer again, together with then superimposed with base plate, be placed in vacuum constant temperature tank, 80-200 DEG C is heated in vacuum tank, vacuum is negative 0.5-1.2 MPa, the permanent negative pressure of constant temperature keeps after 10-20 hour, stop heating, continuing sealing keeps after permanent negative pressure 12-22 hour, open vacuum constant temperature tank naturally to cool, the specification opposite side surplus that last correspondence is different is excised, obtain finished product, the uniform setting of heating rod of described vacuum constant temperature tank inwall, the negative pressure hole in described tank body is symmetrical arranged, and described negative pressure hole is connected with vacuum machine.
Owing to adopting said structure and technique, this composite plate is lightweight, intensity is high, contamination resistance improves, easy for installation, color and decorative pattern uniformity is high, can extensive use, cost low, and can prevent that panel fragmentation from dropping, safety is high, and there is three-dimensional translucent effect.
Accompanying drawing explanation
Fig. 1 is the structural representation that the present invention imitates stone composite board.
