Material is mixed by the weight ratio of 8～10:1～2 by nano-calcium carbonate, color masterbatch.
The principle of the present invention is described as follows:
Corvic:
Although the Corvic SH-200 of high polymerization degree has the most heat-resisting and resistance to low temperature, but it is elastic
Greatly, processing characteristics is poor, and therefore the present invention adds the Corvic WS-1300 of low polymerization degree on its basis, to protect
Card can also meet the requirement of expressing technique while meeting properties of product.
Powder nbr P83:
For modified butadiene acrylonitrile rubber, when P83 elastomer is scattered in PVC base system, P83 elastomer can be polychlorostyrene second
Alkene is coated on centre, forms continuous print network structure.When material is impacted, continuous print network structure can absorb substantial amounts of punching
Hit energy, thus protect material, make material avoid being destroyed；Even if described continuous print network structure is not enough to absorb whole
Impact energy, polrvinyl chloride primary particle also can absorb a lot of energy to protect material, thus significantly improve material when rupturing
Low-temperature flexibility.It addition, P83 elastomer is alternatively arranged as polymeric solid plasticizer, especially when material is in low temperature, this high score
Sub-solid plasticizer will not easy migration precipitation as little molecular fluid plasticizer, this ensure that the low tenderness of polrvinyl chloride
Toughness, improves low temperature impact strength, reduces brittle temperature.
Ethene-vinyl acetate carbonyl copolymer E/VA/CO:
This copolymer, as flexible plasticizer, introduces ketone carbonyl in its system, with the compatibility pole of polrvinyl chloride
Good, it is dispersed in PVC base system as modifying agent and can form network structure, polrvinyl chloride primary particle is positioned at network.When
When material is by external impacts, this network structure can absorb substantial amounts of impact energy, improves the low temperature impact strength of material；Separately
Outward, ethene-vinyl acetate carbonyl copolymer E/VA/CO can make material at consecutive low temperature as polymeric solid plasticizer equally
Environment keeps good performance.
Cold resistant plasticizer di-n-octyl sebacate DOS:
The tolerance to cold of cold resistant plasticizer and its structure have close relationship.The plasticizer tolerance to cold that general intermiscibility is good
The most poor, particularly when containing circulus, tolerance to cold significantly reduces.Di-n-octyl sebacate DOS is as with straight chain methylene
(-CH2-) is that the aliphatic ester of main body has good tolerance to cold, and it introduces the glass transition temperature that can reduce polrvinyl chloride
Degree, thus reduce the brittle temperature of polrvinyl chloride, improve the cold tolerance of material.
Raw materials melt blending step:
Mixing temperature is controlled at 70～90 DEG C by this step, it is easy to the Corvic absorption to liquid plasticizer,
This temperature range mixing 7～8min, it is ensured that plasticizer is absorbed by Corvic completely.
