Embodiment 1

[0023] Embodiment one: if figure 1 The schematic diagram of the structure of the composite board is shown, including the surface layer 1 and the plastic composite substrate layer 2. The surface layer 1 and the plastic composite substrate layer 2 are hot-pressed and pasted together. The pasting of the surface layer 1 and the plastic composite substrate layer 2 is not used. Glue can realize that the composite board does not contain formaldehyde. After reducing the glue coating process, it is easy to realize continuous production, automatic production becomes possible, and the production efficiency is improved. At the same time, the adhesion stability between the layers of the composite board is improved. Surface layer 1 can select plastic film, ceramic tile, glass, rubber, paper, leather, metal, stone material, cloth, carpet, cork etc. for use, and surface layer 1 can also increase decal because of the needs of appearance. The plastic composite substrate 2 is extruded from a lay...

Embodiment 2

[0025] Embodiment two: if figure 2 The schematic diagram of the composite plate structure is shown, the surface layer 1 and the plastic composite substrate layer are heat-compressed and pasted together, wherein the plastic composite substrate layer is extruded and synthesized by two layers of plastic substrates 21, 22, and the two layers of plastic substrates 21, 22 All are extruded and synthesized from a mixture containing PVC powder, heavy calcium and light calcium composite powder, stabilizer, toughener, PE wax, internal lubricant, plasticizer, and impact modifier, and hot-pressed with surface layer 1 The glued plastic substrate 21 has high requirements on hardness and impact resistance. In the plastic substrate mixture formula, increase the proportion of heavy calcium and reduce the proportion of PVC powder and light calcium; plastic substrate 22 has high requirements on hardness and impact resistance. Generally, the ratio of PVC powder and light calcium is increased, the...

Embodiment 3

[0026] Embodiment three: as figure 2 The schematic diagram of the structure of the composite board is shown. The surface layer 1 and the plastic composite substrate layer are heat-compressed and pasted together, wherein the plastic composite substrate layer is extruded and synthesized by three layers of plastic substrates 21, 22, 23, and the three-layer plastic substrate 21 , 22, and 23 are all extruded from a mixture containing PVC powder, heavy calcium and light calcium composite powder, stabilizer, toughener, PE wax, internal lubricant, plasticizer, and impact modifier. Material 22 has low requirements on hardness and impact resistance. Generally, the proportion of PVC powder and light calcium will be increased in the formula of plastic base material mixture, the proportion of heavy calcium will be reduced, and foaming agent will be added; while plastic base material 21, 23 High requirements on hardness and impact resistance, increase the ratio of heavy calcium and reduce ...

Abstract

The invention discloses a composite panel and a production method thereof. The composite panel comprises a surface layer and a plastic composite base material layer, which are subjected to thermocompression bonding; the production method of the composite panel comprises the following steps: proportionally weighing and mixing PVC powder, heavy calcium and light calcium composite powder, a stabilizer, a flexibilizer, PE wax, an inner lubricant, a plasticizer and an impact modifier, and fully stirring a mixture for mixing; extruding the mixed mixture through an extrusion machine to synthesize a plastic composite base material; bonding the surface layer and the plastic composite base material layer together; finally, cooling, sizing and cutting. According to the adoption of the above technical solution, the plastic composite base material does not use wood powder and can save natural timbers; the surface layer and the plastic composite base material are thermally compressed and bonded together without using glue and without containing formaldehyde, the composite panel is formed by one step and a glue coating process is removed, continuous production is easy to realize, and production efficiency is improved; bonding stability among layers of the composite panel is improved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a composite board and a production method thereof. technical background [0002] Existing composite panels, such as WPC composite panels, are mainly divided into three layers: surface layer, panel, printed color film, wear-resistant layer, and WPC base material. The processing method is divided into three steps: the first step is to glue the surface layer and the drawing paper into a whole; the second step is to extrude and shape the wood-plastic composite material WPC base material that needs thickness; The surface layer and the drawing paper and WPC substrate are pressed with glue. Due to the use of wood powder in the WPC substrate, resources are wasted; glue is used for pressing during the processing, and formaldehyde is inevitably contained in the WPC composite board, causing environmental pollution; in addition, the glue coating process is required in the processing proces...
