Abstract
The invention is silicon alkyl cross-linking polyolefin elastomer combination, adopting LLDPE (or ULDPE) and paraffin ot replace EPDM and using silicon grafting system to replace bakelite sulfuration system. It can meet different demands. The components of the compound: PP 2-10 phr; LDPE or ULDPE 50-80 phr; paraffin 50-500 phr; silicon hydride 2-10 phr; peroxide 0.5-2.5 phr; water 0.1-5.0 phr; and anti-oxidizing agent: 0.1-0.3%.
Description
Technical field.
The present invention relates to a kind of elastic composition, particularly a kind of silane crosslinking polyolefin elastic body composition with characteristics such as high strength, ageing-resistant, oil resistants.
Background technology
The main kind of elastomerics is that terpolymer EP rubber (EPDM)/polypropylene (PP) dynamic vulcanization makes at present, as the Monsanto company of the U.S., Dutch DSM N. V. etc. the EPDM/PP elastomer product is arranged all.It is in the mixing tank of high-temperature and high-shear with rubber and resin melt blending, rubber original position sulfuration under the effect of vulcanizing agent, and fine be scattered in the stable dispersion system of formation in the resin.Vulcanization system adopts resol in the prior art of market, generally has certain smell and color, the light goods that are not easy to do, and the cost of EPDM is higher, and the piece material is difficult for processing.
Summary of the invention
The invention purpose is to overcome prior art cost height, be difficult for processing, have shortcomings such as smell and color, and a kind of new elastomerics is provided.New departure will adopt particulate state linear low density polyethylene LLDPE (or ultra-low density polyethylene ULDPE) and paraffin oil to replace EPDM, reduce cost, change vulcanization system auxiliary agent and technology, make the elastomerics odor eliminating, color shoals, so that do not influence the color of follow-up goods.
The concrete composition of silane crosslinking polyolefin elastic body composition is:
PP 30～50phr
LLDPE or ULDPE 50～80phr
Paraffin oil 50～100phr
Silane 2～10phr
Superoxide 0.5～2.5phr
Water 0.1～5.0phr
Oxidation inhibitor is an amount of
Here said " in right amount ", be meant: 0.1～0.3%.
The starting material that the present invention is used, the more traditional EPDM/PP technology cost of cost reduces more than 1/3rd: adopt LLDPE (or ULDPE) and paraffin oil to replace EPDM, replace phenolic resin vulcanization system with silane grafting system.Replace expensive terpolymer EP rubber (EPDM) with lower LLDPE of price (or ULDPE) and paraffin oil, elastomeric cost is reduced greatly, with the difference of paraffin oil content, prepared elastomerics modulus variable range is very big, can satisfy the needs of different purposes simultaneously.Vulcanization system adopts silane grafting and water crosslinking, and can make elastomeric article not be with smell and keep true qualities, no colour-change, also odorlessness is convenient to prepare the elastomerics end article of various different colours, can satisfy the needs of different purposes.
