PVC foam antibacterial board and preparation method thereof

Abstract

The invention belongs to the technical field of polyvinyl chloride boards, and in particular relates to a PVC foamed antibacterial board and a preparation method thereof. The PVC foam antibacterial board includes a core layer and a skin layer, and the skin layer includes an upper skin layer and a lower skin layer; the upper surface of the core layer is connected to the upper skin layer, and the lower surface of the core layer is connected to the lower skin layer; the core layer is filled with PVC resin powder Ⅰ, Agent I, foaming regulator, composite foaming agent, calcium-zinc stabilizer, soybean oil, lubricant, regrind and pigment; the raw material of the upper skin layer and the lower skin layer is the same, consisting of PVC resin powder I, PVC resin powder Ⅱ, Filler Ⅱ, processing aids, high-efficiency modifiers, compound antibacterial agents, weather resistance modifiers, anti-purple modifiers, calcium zinc stabilizers, lubricants and pigments. The PVC foamed antibacterial board of the present invention has the advantages of high antibacterial effect, green environmental protection, safety and long-term effect, tensile and folding resistance, high screw holding force, low comprehensive use cost, high cost performance, and wide application range.

Description

technical field [0001] The invention belongs to the technical field of polyvinyl chloride boards, and in particular relates to a PVC foamed antibacterial board and a preparation method thereof. Background technique [0002] At present, with the rapid development of domestic and foreign furniture and decoration industries, wooden boards and plywood are usually used in traditional decoration, decoration and cabinet making; Intensive care rooms, etc.), special cabinets and decorations for home decoration (bathroom and kitchen cabinets), etc., are often deformed due to moisture, and cannot be opened or closed tightly, which seriously affects the use effect, wastes forest resources, and is not conducive to environmental protection. , and the board will produce mold, mildew, rot, etc. when it is damp and used for a long time; in some areas with high environmental requirements, such as antibacterial and aseptic environments, the existing boards cannot solve the problem of mold resi...

AI Technical Summary

Problems solved by technology

[0002] At present, with the rapid development of domestic and foreign furniture and decoration industries, wooden boards and plywood are usually used in traditional decoration, decoration and cabinet making; Intensive care rooms, etc.), special cabinets and decorations for home decoration (bathroom and kitchen cabinets), etc., are often deformed due to moisture, and cannot be opened or closed tightly, which seriously affects the use effect, wastes forest resources, and is not conducive to environmental protection. , and the board will produce mold, mildew, rot, etc. when it is damp and used for a long time; in some areas with high environmental requirements, such as antibacterial and aseptic environments, the existing boards cannot solve the problem of mold resistance and rot.

[0003] Polyvinyl chloride foam board is a new type of board for cabinets. Although it solves the problem of moisture deformation, the polyvinyl chloride foam cabinet boards in the prior art are often not antibacterial, poor weather resistance, easy to fade and turn yellow, and are often damaged during use. Easy to crack, easy to deform, low screw holding force, easy to loosen and fall off the fixing screws, and the cost is higher than that of wood and plywood, which seriously affects its popularization and use
