Description
Technical field
The invention belongs to technical field of rubber material, in particular to a kind of lignin/ternary ethlene propyene rubbercompound material and
Preparation method.
Background technique
Ethylene propylene diene rubber, abbreviation EPDM are the terpolymers of ethylene, propylene and non-conjugated diene hydrocarbon, are had good
Chemicals-resistant, electrical insulating property, cryogenic property, can be widely used for building materials waterproof material, automobile component, electric wire and cable jacket,
In other products such as heat-resistant rubber hose, adhesive tape and automotive sealant.But ethylene propylene diene rubber belongs to amorphism rubber, does not have
It is standby to need to add a large amount of reinforcement/filler in actual processing to improve its physical mechanical property from reinforcing, such as carbon black,
The fillers such as white carbon black, calcium carbonate.In addition, the thermo oxidative aging and resistance to UV aging of rubber itself are insufficient, need to add small
The antioxidant and light stabilizer of molecule, such as Hinered phenols, hindered amines there are migration, extraction, have certain toxicity and can make
The problems such as at environmental pollution.
Lignin is the second largest biomass resource that cellulose is only second in plant, and degradable, nonhazardous is with aromatic ring
The natural polymer of structure, the feature structures such as phenyl ring, phenolic hydroxyl group in molecule make it have excellent uvioresistant spoke
It penetrates and anti-aging property [Green Chem., 2015,17 (1): 320-324.].Traditional carbon black or nothing are replaced using lignin
Machine filler enhances ethylene propylene diene rubber, prepares lignin/rubber composite wood with excellent uvioresistant, anti-aging property
Material can not only reduce the cost of rubber material, while lignin can play processing stabilizers, anti-short UV light is stablized
Agent, anti-aging effect.But since EPDM is nonpolar polyolefin hydro carbons rubber, and containing a large amount of more in lignin molecule
Phenol and quinoid isopolarity functional group, intermolecular force is strong, easily reunites, and causes it with rubber matrix poor compatibility and not
Easily dispersion [China Synthetic Rubber Industry, 2001,24 (1): 51-55.].
It is blended both at home and abroad in relation to lignin with ethylene propylene diene rubber at present and prepares the work of composite material and be rarely reported.Wang Xiao
Victory et al. report it is a kind of using organosolv lignin enhancing ethylene propylene diene rubber method [using chemical industry, 2008,37 (11):
1316-1319].In this method, lignin needs first to carry out modified by maleic acid anhydride graft, then with SiO2Nanocomposites preparation
At lignin grafted maleic anhydride/Nano-meter SiO_22Compound particle, then vulcanize with rubber mill, the stretching of resulting materials before ageing
Intensity only up to reach about 8MPa, and elongation at break highest only has 400% or so.And most of research work is all to utilize fibre
Dimension, carbon black or other inorganic fillers are blended with ethylene propylene diene rubber and prepare composite material.For example, Airinei et al. [Polymer
Testing2017,59:75-83.] flax fiber and EPDM high-temperature mixing are used, the tensile strength of gained composite material is lower, nothing
Method meets requirement.Naderi et al. [Composites Science and Technology 2017,141:83-98.]
Trielement composite material, resulting materials better performances, but higher cost are made into graphene film, polypropylene, EPDM.Patent
CN105199244A discloses a kind of preparation method using textile-like fibre reinforced ethylene propylene diene rubber.This method is using big
The carbon-fiber textiles of amount carry out solubilizer processing as reinforcing agent, and firstly the need of to textile-like carbon fiber, need to finally adopt
It is crosslinked with gamma Rays, prepared composite material strength is higher, but preparation process is complicated, and higher cost is unfavorable
In large-scale application.Therefore, how using cheap industrial lignin to enhance ethylene propylene diene rubber as reinforcing agent, realize wood
Quality had not only enhanced rubber but also the effect of toughening, is current research significant difficulty urgently to be solved.
