Embodiment 1

[0037] Calculated in parts by weight, the components of the PVC composite material are: 45 parts of PVC (8 parts containing CPVC); 60 parts of calcium carbonate; 2.4 parts of toughening agent CPE; 1.1 parts of lubricant (0.55 parts of stearic acid+PE wax 0.55 parts); 2.1 parts of stabilizer (1.05 parts of calcium stearate + 1.05 parts of zinc stearate); 0.1 part of toning powder; no added plant fiber. The composition distribution of this embodiment is relatively balanced, and a relatively neutral (relative to other embodiments) excellent product can be obtained.

Embodiment 2

[0039] Calculated by weight, the components of the PVC composite material are: 55 parts of PVC (5 parts containing CPVC); 70 parts of calcium carbonate; 3.6 parts of toughening agent ACR; 0.9 parts of lubricant (0.45 parts of stearic acid+PE wax 0.45 parts); 2.3 parts of stabilizer (1.15 parts of calcium stearate + 1.15 parts of zinc stearate); 0.01 part of toning powder; no added plant fiber. This embodiment basically does not have color toning, and is suitable for occasions such as plate core boards and substrates.

Embodiment 3

[0041] Calculated in parts by weight, the components of the PVC composite material are: 48 parts of PVC (7 parts containing CPVC); 60 parts of calcium carbonate; 3.1 parts of toughening agent ACR; 1.0 parts of lubricant (0.5 parts of stearic acid+PE wax 0.5 part); 2.0 parts of stabilizer (1 part of calcium stearate + 1 part of zinc stearate); 0.04 part of toning powder; no added plant fiber. In this embodiment, the ratio of PVC component and calcium carbonate is low, and the toughness is better.

Abstract

The embodiment of the invention discloses a hollow board. According to the hollow board, uniformly mixed PVC (polyvinyl chloride) composite materials are fused and is processed by a mouth mold of a plastic extruding machine to obtain extrudate; the extrudate is cooled and shaped to obtain a board-shaped body; a strip hole array is formed inside the board-shaped body; the wall thicknesses of upper and lower cross walls of the strip hole array and rib thicknesses of vertical ribs between the adjacent strip holes can ensure strength of the board-shaped body. The embodiment of the invention also discloses a composite board which comprises a light-transmitting and waterproof wear-resistant layer, a color film layer with a decorative pattern and a base layer formed by the hollow board, wherein the light-transmitting and waterproof wear-resistant layer, the color film layer and the base layer are sequentially combined from top to bottom. The hollow board and the composite board which are disclosed by the embodiment of the invention have good waterproofness and mute effect and can be used as floors, ceilings, door plates, wall decoration boards and the like.

Description

technical field [0001] The invention relates to board material manufacturing technology, in particular to a hollow board and a composite board, which can be widely used in occasions such as floors, ceilings, door panels, wall decoration boards and the like. Background technique [0002] At present, office, home and other environments have higher and higher requirements for panels, such as waterproof and quiet performance is an important assessment index. In the existing board supply and demand market, users usually choose waterproof and silent boards based on PVC foam boards (also known as Chevron boards and Andy boards). The main chemical composition of this PVC foam board is polyvinyl chloride polymer. During production, the mixed materials such as PVC and foaming agent are foamed at high temperature, and then the melt is extruded by the extruder and sent to the mold for molding. And cooled, then cut into the desired plate after shaping. The cost of this kind of PVC foam...
