Abstract
The invention provides an anti-aging polyvinyl chloride material. The anti-aging polyvinyl chloride material is prepared from the following raw materials in parts by mass: 100 parts of polyvinyl chloride, 0.1-1 part of nanometer samarium oxide, 1-10 parts of superfine inorganic particles, 0.1-1 part of an ultraviolet absorption agent, 0.01-0.5 part of a rare earth coupling agent, and 10-30 parts of adjuvant agents. The anti-aging polyvinyl chloride material is prepared through the following steps of firstly performing surface modification treatment on the inorganic particles and the nanometer samarium oxide by using the rare earth coupling agent; and then adding the modified inorganic particles and the modified nanometer samarium oxide to the polyvinyl chloride, separately adding the ultraviolet absorption agent and other adjuvant agents, performing high-speed uniform mixing, and then performing milling by a roll mill at 160-180 DEG C for 5-10 minutes, so as to obtain the anti-aging polyvinyl chloride material. The polyvinyl chloride material has good anti-aging properties, and excellent comprehensive mechanical properties.
Description
Technical field
The invention belongs to field of polyvinyl chloride material, it relates to a kind of anti-aging pvc material.
Background technology
Polyvinyl chloride is a kind of general plastics, and it has outstanding comprehensive mechanical property, but polyvinyl chloride also also exists the shortcoming of light stability difference, and under ultraviolet effect, polyvinyl chloride is easily degraded, and causes mechanical properties decrease. So improving the ultraviolet resistance of pvc material, improve its anti ageing property the application of polyvinyl chloride is most important, can reach, by adding UV light absorber and other inorganic particulates, the object improving its anti-aging, and inorganic particulate add mechanical property and the resistance toheat that can effectively improve pvc material.
Summary of the invention
It is an object of the invention to provide a kind of anti-aging pvc material, the anti ageing property of this material is good, and comprehensive mechanical property is excellent.
For realizing above-mentioned object, the technical solution used in the present invention is:
A kind of anti-aging pvc material, it is characterised in that, its raw material and raw materials quality part is:

Rare-earth coupling agent 0.01～0.5 part,
Auxiliary agent 10～30 parts.
Preferably, described micro-sized inorganic particles is the one of superfine silicon dioxide, superfine titanic oxide.
Preferably, described UV light absorber is the one of UV-1130, UV-234, UV-531, UV-328.
Preferably, described auxiliary agent be softening agent, oxidation inhibitor, thermo-stabilizer, lubricant, anti-impact modifier one or more.
Present invention also offers the preparation method of a kind of anti-aging pvc material, comprise the following steps:
(1) adopt rare-earth coupling agent that inorganic particulate and nano oxidized samarium are carried out surface modification treatment;
(2) modified inorganic particulate and nano oxidized samarium are joined in polyvinyl chloride, add UV light absorber and other auxiliary agents more respectively, high-speed mixing is even, then mixing 5～10min at 160～180 DEG C on a mill until, obtaining anti-aging polyvinyl chloride, this material can carry out subsequent forming to be processed into goods.
The useful effect that the present invention has:
(1) UV light absorber add the light stability that can improve polyvinyl chloride, the anti ageing property of polyvinyl chloride can be improved;
(2) inorganic particulate add the anti ageing property that can improve polyvinyl chloride, inorganic particulate can stop UV-light to enter into the inside of polyvinyl chloride, absorb with light reflection ultraviolet to reach the object of anti-aging, and collaborative antiultraviolet effect can be reached with UV light absorber, remarkably productive;
(3) give the good ray shield performance of polyvinyl chloride adding of nano oxidized samarium, be conducive to the raising of anti ageing property;
(4) adopt rare-earth coupling agent that inorganic particulate is carried out surface modification, it is possible to better to improve the interface binding power of inorganic particulate and polyvinyl chloride, it is to increase the mechanical property of polyvinyl chloride composite materials.
