Description
Technical field
The present invention relates to a kind of blend rubber resilient material and preparation method thereof, particularly relating to a kind of take LNBR as NBR/PVC elastomerics of softening agent and preparation method thereof.
Background technology
Paracril (NBR) has excellent oil-proofness, thermotolerance and physical and mechanical properties, but its ozone-resistant aging property is poor; General synthetic resin polyvinyl chloride (PVC) then has excellent flame retardant resistance, self-extinguishing and resistance to ozone ageing, chemical resistance, electrical insulating property, chemical stability and thermoplasticity, but its toughness is low, and not shock-resistant, resistance toheat is poor.
NBR and PVC is all polar polymer, the two solubility parameter close (being followed successively by 9.64,9.6 respectively), consistency is very good, can arbitrary proportion blending, is not only combined both performance advantages by the two blended matrix material made, compensate for respective defect, and improve extrusion, drawability, sizing material not easily self-vulcanizing, enhances shelf-stable simultaneously, becoming a kind of important Novel rubber plastic composite, is also the pioneer of rubber and plastic.LNBR is as a kind of new liquid softening agent and Rubber Softener, itself and paracril have similar molecular structure, while playing plastification, in rubber vulcanization process, also can participate in co-crosslinking, make its solvent resistant extractable be much better than other conventional plasticizers.
Have part document and patent to report about NBR/PVC Blend rubber, but be that the elastomeric research of NBR/PVC of softening agent has no report with LNBR, thus to LNBR be the elastomeric research of NBR/PVC of softening agent highly significant.Paracril (NBR) and the Blend rubber of polyvinyl chloride (PVC) have been the principal item of current rubber and plastic, because it has the two excellent properties concurrently and raw material sources is abundant, cheap, so application is quite extensive, market outlook are had an optimistic view of.
Summary of the invention
The object of the present invention is to provide a kind of take LNBR as NBR/PVC elastomerics of softening agent and preparation method thereof, improving elastomeric ozone resistance by adding polyvinyl chloride in paracril, is that softening agent improves elastomeric resistance to fatigue and solvent resistant extractable with LNBR.Be suitable for making the products such as oil resisting rubber hose, printing rubber roll, bladder, expand the use range of rubber product.
The object of the invention is to be achieved through the following technical solutions:
A kind of take LNBR as the NBR/PVC elastomerics of softening agent, described NBR/PVC elastomerics is made up of the constituent of following mass parts: paracril (NBR) 70 parts, polyvinyl chloride (PVC) 30 parts, strengthening agent 10 ~ 50 parts, 10 ~ 30 parts, softening agent, 2.5 ~ 3.5 parts, anti-aging agent, vulcanizing agent 1.0 ~ 2.0 parts, vulcanization leveller 5.0 ~ 7.0 parts, vulcanization accelerator 1.0 ~ 2.0 parts, stablizer 1.5 ~ 2.0 parts.
Described a kind of take LNBR as NBR/PVC elastomerics of softening agent and preparation method thereof, described softening agent is LNBR, and its solvent resistant extractable is much better than other conventional plasticizers, as o-phthalic acid dibutyl ester (DOP).
Described a kind of take LNBR as NBR/PVC elastomerics of softening agent and preparation method thereof, described strengthening agent carbon black model is respectively N220, N330, N550, N774.
Described a kind of take LNBR as NBR/PVC elastomerics of softening agent and preparation method thereof, described stablizer is barium zinc composite stabilizer.
Described a kind of take LNBR as NBR/PVC elastomerics of softening agent and preparation method thereof, described vulcanizing agent is Sulfur, dicumyl peroxide (DCP), and vulcanization accelerator is one or more of TMTD, CZ.
Described a kind of take LNBR as NBR/PVC elastomerics of softening agent and preparation method thereof, described anti-aging agent is N-sec.-propyl-N'-diphenyl-para-phenylene diamine (4010NA), 2,2,4-trimethylammonium-1,2-dihyaroquinoline polymer (RD).
Take LNBR as a NBR/PVC elastomers method for softening agent, described method comprises the preparation process of its rubber unvulcanizate and cross-linked rubber thereof:
(1) NBR plasticates: plasticated on opening rubber mixing machine by NBR, and adds anti-aging agent and mix;
(2) NBR/PVC is blended: plasticator is heated to 150 ~ 160 DEG C, is placed on plasticator roller, plastifies mixing the PVC/ stablizer that stirrer mixes with height, and it is blended to add NBR when reaching plastifying state, mixes rear bottom sheet, cools for subsequent use;
(3) prepare rubber unvulcanizate: the NBR/PVC Blend rubber of step (2) gained be placed on mill two roller, add ZnO, stearic acid, Sulfur successively, mixing evenly after add carbon black, further mixing evenly after add softening agent (LNBR), vulcanization accelerator; Rubber unvulcanizate is played triangle bag 10 times afterwards, mixes bottom sheet, park 24 hours stand-by;
(4) the film back mixing bottom sheet again step (3) prepared, records t with without rotor vulkameter
10, t
90; Then on vulcanizing press 165 DEG C, 10Mpa carries out sulfuration, after arriving curing time, take out cross-linked rubber, by its naturally cooling, be namely able to the NBR/PVC elastomerics that LNBR is softening agent, for test.
Advantage of the present invention and effect are:
The a kind of of invention take LNBR as the NBR/PVC elastomerics of softening agent, using NBR and PVC two kinds of elastomericss as material of main part, because LNBR and NBR has similar structure, while playing plastification, also take part in the co-crosslinking in sulfidation, its solvent resistant extractable is much better than other conventional plasticizers.In NBR/PVC Blending Processes and mixing process, add LNBR can effectively reduce elastomeric mooney viscosity, improve processing characteristics, improve compression performance, fatigue performance, its oil resistant extraction performance is good simultaneously.Therefore very large utility value is had in fields such as oil resisting rubber hose, printing rubber roll, bladders.
