Embodiment 1

[0026] Take 100 parts of PVC, 4 parts of calcium zinc stabilizer, 6 parts of ACR impact modifier, 7 parts of titanium dioxide, 15 parts of light calcium carbonate, and 1.8 parts of ACR processing aid. First, prepare the mixture. The raw materials are put into a high-speed hot mixer, rubbed and sheared by high-speed rotating blades, and discharged into a low-speed cold mixer when the temperature rises to 115°C, uniformly stirred at a low speed and cooled to 45°C to obtain a mixture. The mixture is extruded into profiles with a conical twin-screw machine.

Embodiment 2

[0028] Take 100 parts of PVC, 4 parts of calcium zinc stabilizer, 5 parts of ACR impact modifier, 6 parts of titanium dioxide, 15 parts of light calcium carbonate, and 1.5 parts of ACR processing aid. Operation is with embodiment 1.

Embodiment 3

[0030] Take 100 parts of PVC, 4 parts of calcium zinc stabilizer, 6 parts of ACR impact modifier, 6 parts of titanium dioxide, 10 parts of light calcium carbonate, and 1.8 parts of ACR processing aid. Operation is with embodiment 1.

[0031] According to the national standard artificial weathering resistance test results:

Abstract

The invention discloses an environment-friendly aging-resistant polyvinyl chloride (PVC) section. The PVC section consists of PVC resin, an environment-friendly stabilizer, light calcium carbonate, titanium white, an acrylic (ACR) impact modifier, an ACR processing aid and stearic acid. The PVC section has the advantages of environment friendliness, aging resistance, high shock resistance and the like, has good processing performance and can be popularized and applied.

Description

technical field [0001] The invention relates to the field of materials, in particular to an environment-friendly and aging-resistant PVC profile. Background technique [0002] In recent years, with the popularity of PVC plastic-steel doors and windows in people's lives, people pay more attention to the service life and anti-aging performance of door and window profiles. At present, the poor anti-aging performance of door and window profiles is a common problem. The current national standard GB / T8814-2004 for white profiles has higher requirements on the aging performance of profiles, and the testing methods are more stringent. At present, the aging performance of ordinary white PVC profiles is difficult to meet the requirements of the new standard GB / T8814-2004. PVC itself will age and turn yellow over time. This phenomenon becomes apparent under prolonged exposure to sunlight (mainly the effect of ultraviolet light). [0003] At present, the commonly used anti-impact ...
