Problems solved by technology

[0002] At present, most of the anti-yellowing PVC wire and cable materials are mostly dark-colored, and it is easy to appear abrupt for some installation locations that require a latent color appearance.
And after a long time of use, even the darkest color will inevitably appear a lot of yellowing, lacking a long-lasting anti-yellowing
At the same time, the anti-yellowing polyvinyl chloride products on the market are relatively deficient in weather resistance and migration resistance, and cannot be applied to the manufacturing and application fields of wires and cables, nor do they meet the requirements of UL62, UL83, UL758 and UL1581 standards

Embodiment 1

[0031] The processing steps are as follows: First, add polyvinyl chloride resin, plasticizer, stabilizer, antioxidant, ultraviolet absorber, lubricant, pigment, calcium carbonate filler and other additives into the high-mixer according to the ratio in the table mix.

[0032] components Weight(KG) percentage(%) PVC 100 44.9 plasticizer 65 29.2 stabilizer 3 1.3 antioxidant 0.4 0.18 UV absorber 3 1.3 lubricant 0.5 0.22 pigment 0.2 0.9 calcium carbonate 48 20 other 4.5 margin

[0033] After that, after the temperature of the material in the high mixer rises to 100°C, put the material in the high mixer into the cooling mixer. Next, after the material is cooled and mixed to about 45°C, the material in the cooling mixer is discharged. Subsequently, the mixed materials are fed into an extrusion granulator, and the temperature of the extruder barrel and head is controlled within the range of 135-150°C. F...

Embodiment 2

[0035] The processing steps are as follows: First, add polyvinyl chloride resin, plasticizer, stabilizer, antioxidant, ultraviolet absorber, lubricant, pigment, calcium carbonate filler and other additives into the high-mixer according to the ratio in the table mix.

[0036] components Weight(KG) percentage(%) PVC 100 49.2 plasticizer 52 25.6 stabilizer 4 1.9 antioxidant 0.4 0.19

[0037] components Weight(KG) percentage(%) UV absorber 4 2 lubricant 0.6 0.29 pigment 0.21 0.1 calcium carbonate 38 18.7 other 4 margin

[0038] The remaining steps are the same as those in Embodiment 1 and will not be repeated here.

Embodiment 3

[0040] The processing steps are as follows: First, add polyvinyl chloride resin, plasticizer, stabilizer, antioxidant, ultraviolet absorber, lubricant, pigment, calcium carbonate filler and other additives into the high-mixer according to the ratio in the table mix.

[0041] components Weight(KG) percentage(%) PVC 100 45 plasticizer 60 27 stabilizer 3 1.4 antioxidant 0.3 0.14 UV absorber 4 1.8 lubricant 0.5 0.23 pigment 0.2 0.09 calcium carbonate 44 19.8 other 10 margin

[0042] The remaining steps are the same as those in Embodiment 1 and will not be repeated here.

[0043] To sum up, the present invention adopts a scientific formula, which can make polyvinyl chloride achieve better anti-yellowing characteristics, and more importantly, the finished product of polyvinyl chloride appears white, and the coloring is firm, and has good anti-yellowing properties. Weather resistance and migration resis...

Abstract

The invention relates to anti-yellowing PVC which belongs to the technical field of organic polymer compounds. The invention comprises the following components (weight percent): 41 to 50 percent of PVC, 24 to 30 percent of plasticizer, 1 to 3 percent of stabilizer, 0.1 to 0.2 percent of antioxidant, 1 to 4 percent of UV absorbent, 0.1 to 1 percent of lubricant, 0.03 to 0.1 percent of pigment, and 15 to 20 percent of filler. The invention can cause the PVC to achieve better anti-yellowing property, and the finished goods are white and have good weather and transfer resistance effects.

Description

technical field [0001] The invention relates to a polyvinyl chloride, in particular to an anti-yellowing, weather-resistant and migration-resistant polyvinyl chloride, which belongs to the technical field of organic polymer compounds. Background technique [0002] At present, most anti-yellowing polyvinyl chloride wire and cable materials are mostly dark-colored, which is easy to appear abrupt for some installation locations that require a latent color appearance. And after a long time of use, even the darkest color will inevitably show a lot of yellowing, lacking a long-lasting anti-yellowing. At the same time, the existing anti-yellowing PVC products on the market lack weather resistance and migration resistance, which cannot be applied to the manufacturing and application of wire and cable, and do not meet the requirements of UL62, UL83, UL758 and UL1581 standards. Contents of the invention [0003] The object of the present invention is to provide a kind of polyvinyl ...
