Abstract
The invention discloses the production methods of cis-butenedioic anhydride graft type butylbenzene ground rubber.This method is to be uniformly mixed cis-butenedioic anhydride, auxiliary agent, useless sbr powder in a high speed mixer；Subsequently into multi-functional rubber and plastic processing unit (plant), under microwave action, sbr powder chain rupture regeneration of giving up, while graft reaction occurs for cis-butenedioic anhydride and butadiene-styrene rubber, and graft type butylbenzene ground rubber is made.Production method of the invention avoids the autohemagglutination of grafted monomers under hot conditions, polymer decomposes and volatile organic gases generates, and is conducive to environmental protection, while improving material property.
Description
Technical field
The present invention relates to the production methods of cis-butenedioic anhydride graft type butylbenzene ground rubber, belong to high molecular material graft modification technology
Field.
Background technique
Non-polar polymer and other materials, such as polar polymer, inorganic filler compatibility are very poor, can not prepare useful
Intermingling material.Expanding material that is previously prepared or being formed in situ is added, script incompatible polymers can be made to be formed with any
The blend for the peculiar property that component does not have.
So far, due to cheap, high activity and good processability, maleic anhydride grafted polymer is most important function
Can change material, improve the interfacial adhesion in blend between dispersed phase and continuous phase, it blend polymer, polymer/
Inorganic filler, polymer/organic fiber, composite reinforcing material and binder etc. are all widely used.Maleic anhydride with
Polyolefine material has good grafting performance, while can assign its polarity and new reactivity and be widely used, on the one hand
Determined by the structure of its carbon-to-carbon double bond, radical reaction and photochemical reaction can be participated in, on the other hand acid anhydrides as contained by it or
The reactivity of carboxylic acid group, some groups or molecule can occur amidation, esterification etc. with it and react.
Although useless sbr powder has very high elasticity, excellent ageing-resistant performance, its polarity is low, with resin compatible
Difference can occur serious two-phase laminated flow after simple blend, lead to the degradation of blend, it is therefore necessary to carry out to useless sbr powder
Graft modification.
The reactive acid anhydrides or carboxylic acid group of the useless sbr powder of graft modification polarized on side chain, can be with polarity
Resin has preferable compatibility, and can chemically react with polar resin；And main chain has with the rubber in useless butylbenzene
Good compatibility, therefore the performance of blend can be greatlyd improve after being added.
The preparation method of the useless sbr powder of graft modification mainly uses ultraviolet light solid-state grafting: using acetone, hydroxide
Sodium, hydrochloric acid, deionized water are washed, are dried；Then use benzophenone for photosensitizer, with maleic anhydride, acetone or other
Solvent is by lighting process in ball milling, ultraviolet case.This method consumes a large amount of acid, alkali, acetone, deionized water, it is also necessary to ball milling
Machine processing, complex process, investment is high, energy consumption is high.
To solve the above problems, the present inventor studies, develops the life of cis-butenedioic anhydride graft type butylbenzene ground rubber
Production method.
Summary of the invention
Microwave heat and induced chemical reaction in terms of be widely used, application is more especially in terms of induced chemical reaction
By force.Microwave heating be using heated material polar molecule in microwave electromagnetic field (frequency 2450MHz) fast steering and
It aligns, to generate tearing and phase mutual friction and generate heat.Microwave induction catalytic reaction is by high-intensitive short pulse microwave spoke
It penetrates and focuses on the solid catalyst bed surface containing certain " substance ", due to the strong work of surface metal point and microwave energy
With microwave energy will be converted heat, to make certain surface points be selectively heated to very high temperature quickly, in reactor
Material can react when contacting with the surface point being stimulated.
Microwave technology Heterosis exists: (1) microwave has very strong penetrability, and homogeneous heating can directly act on and be added
Hot substance makes to heat and act on together inside and outside it, and moment can reach predetermined temperature；(2) it is transported at a high speed under microwave electromagnetic field action
It is dynamic, the contact probability of auxiliary agent and material is greatly increased, contact interface is constantly updated, thus can increase substantially reaction speed,
And auxiliary agent is made to be fully used.(3) microwave treatment be not in hot-spot, it is partially carbonized, agglomeration phenomena such as, it is easy to accomplish
Automation, mitigates the working strength of operator.
The multi-functional rubber and plastic processing unit (plant) that the present invention uses is the entitled multi-functional rubber and plastic processing unit (plant) (patent No.
CN201720960911 the equipment described in).
Therefore, the present invention provides the production technology schemes of following cis-butenedioic anhydride graft type butylbenzene ground rubber:
1, the production method of cis-butenedioic anhydride graft type butylbenzene ground rubber, it is characterised in that: (1) by the measured cis-butenedioic anhydride of poidometer, auxiliary agent,
Useless sbr powder is uniformly mixed in a high speed mixer；(2) under nitrogen protection state, by cis-butenedioic anhydride, auxiliary agent, useless butadiene-styrene rubber
Powder mixture is added under multi-functional rubber and plastic processing unit (plant) stirring and preheats；(3) start microwave generator, it is anti-under microwave action
It answers 10-150 minutes, makes useless sbr powder chain rupture regeneration, while making cis-butenedioic anhydride and butadiene-styrene rubber molecule that graft reaction occur, be made and connect
Branch type butylbenzene ground rubber.
2, the partial size of useless sbr powder is -100 mesh of 20 mesh.
3, cis-butenedioic anhydride additional amount is the 0.3-10% of useless sbr powder quality.
4, auxiliary agent is the mixture of peroxide cumyl peroxide Yu filler phthalic acid ester；Peroxide mistake
Oxidation diisopropylbenzene (DIPB) additional amount is the 0-0.10% of useless sbr powder quality, and filler phthalic acid ester additional amount is useless butylbenzene
The 0-10% of rubber powder quality.
5, cis-butenedioic anhydride, auxiliary agent, useless sbr powder mixture are 30 DEG C -70 DEG C in the preheating temperature of multi-functional rubber and plastic processing unit (plant).
The thermos have the advantages that
1, using high-speed mixer, cis-butenedioic anhydride, auxiliary agent, useless sbr powder can be made to be sufficiently mixed uniformly.
2, using nitrogen protection, it can prevent material from oxidation side reaction occurs.
3, cis-butenedioic anhydride, auxiliary agent, useless sbr powder mixture preheating temperature are 30 DEG C -70 DEG C, microwave can be made directly to make
