Problems solved by technology

The sheet is a two-sided gloss board, the surface of the material is poor in printability, the printed ink is easy to fall off, and there are also deficiencies in antibacterial, mildew-proof, rigidity, etc.
Because after the lampshade is made of PVC sheet, it is easy to accumulate dust and humid air after long-term use, which will breed bacteria and mildew, which will affect the appearance.

Embodiment 1

[0033] Implementation 1: Production of antibacterial and mildew-proof PVC semi-matte sheets for lighting

[0034] 1. Preparation

[0035] Weigh 700Kg of polyvinyl chloride, 20Kg of titanium dioxide, 150Kg of nano calcium carbonate, 20Kg of matte polyvinyl chloride, 5Kg of antibacterial agent ZnpT, 7Kg of antifungal agent HAS-FAM, 68Kg of reinforcing agent, 10Kg of heat stabilizer, and 15Kg of lubricant.

[0036] 2. Processing steps:

[0037] 1. Stir the molten material. Put the above-mentioned measured raw materials into a high-speed mixer, fully stir and mix evenly, and stir until the material temperature is 100-110°C;

[0038] 2. Stir and cool the material. Discharge the high-speed stirred material to the low-speed cooling mixer for cooling and stirring, and stir to reduce the temperature of the material to 40-45°C;

[0039] 3. Plasticization of extruder The cooled material is uniformly input into the planetary extruder for plasticization. The temperature of the planetary ...

Embodiment 2

[0047] The difference between embodiment 2 and embodiment 1 is only that the proportioning of each raw material is different: polyvinyl record 650Kg, titanium dioxide 15Kg, nano calcium carbonate 140Kg, matting agent 30Kg, antibacterial agent ZnpT 6Kg, antifungal agent HAS-FAM 8Kg , Strengthening agent 70Kg, heat stabilizer 15Kg, and lubricant 15 Kg.

[0048] All the other are with embodiment 1.

Embodiment 3

[0050] The difference between embodiment 3 and embodiment 1 is only that the proportioning of each raw material is different: polyvinyl chloride 680Kg, titanium dioxide 20Kg, nano calcium carbonate 120Kg, matting agent 35Kg, antibacterial agent ZnpT 9Kg, antifungal agent HAS-FAM 9Kg , Strengthening agent 67Kg, heat stabilizer 14Kg, and lubricant 15 Kg.

Abstract

The invention relates to a PVC semi-matte sheet for an anti-microbial and mould-proof light fixture. Polyvinyl chloride is taken as the main material, titanium dioxide and nano calcium carbonate are added to serve as filler, and delustering agent, anti-microbial agent, mildew preventive, fortifier, heat stabilizer and lubricant are added to serve as auxiliaries. The PVC semi-matte sheet contains, by weight, 65-70% of polyvinyl chloride, 1-2% of titanium dioxide, 12-15% of nano calcium carbonate, 2-4% of delustering agent, 0.5-1% of anti-microbial agent, 0.5-1% of mildew preventive, 5-8% of fortifier, 1-1.5% of heat stabilizer and 1-1.5% of lubricant, and the total percentage of all the components is 100%. The light fixture sheet produced based on the blending method has the advantages of being high in anti-microbial and mould-proof rigidity and tenacity, excellent in printing performance and the like.

Description

technical field [0001] The invention relates to the technical field of PVC hard sheets, in particular to a PVC semi-matt sheet for antibacterial and anti-mildew lighting decorations and a preparation method thereof. Background technique [0002] PVC hard sheet is a material for making lighting. At present, various lampshade manufacturers at home and abroad use PVC hard sheets. The sheet is a two-sided gloss board, the surface of the material has poor printability, the printed ink is easy to fall off, and there are deficiencies in antibacterial, mildewproof, rigidity and the like. Because after the lampshade is made of PVC sheet, it is easy to accumulate dust and humid air after long-term use, which will breed bacteria and mildew, which will affect the appearance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a kind of PVC semi-matt sheet for antibacterial and mildew-proof lighting in view of the above-mention...
