Description
Technical field
The present invention relates to technical field of composite preparation, specially a kind of modified SBS composite-material formula of highly resistance folding
And its preparation process.
Background technique
Polystyrene-polybutadiene-polystyrene block copolymer (SBS) is good, inexpensive with chemical stability and processes
Convenient advantage is one of general-purpose plastics important in current industrial application, but its impact strength is not high, easily-deformable, and
Also application and transport can be restrict due to its fracture resistance difference in practical applications, be based on drawbacks described above, seriously limit SBS
Extensive use.
In order to expand the application field of SBS, toughening is generally carried out to SBS using inorganic rigid particle, improves the strong of material
Degree and toughness, but since the surface between inorganic rigid particle and SBS can differ larger, interfacial bonding is weak, makes phase between the two
Capacitive is poor, easily reunites, and affects dispersion of the inorganic rigid particle in SBS matrix, seriously limits modified effect.
In existing technical solution, a kind of ageing-resistant sisal fiber such as announced application No. is 201710551038.1 changes
Property SBS composite material, makes it have anti-aging and shock proof ability by multiple correlation material.But in summary technology
Scheme and reality there are the problem of, and combine the technical solution being widely used at present, there is also the main body of major defect
Present the following aspects:
(1) in existing formula, often lack the substance of facilitation, so that can not between SBS and other ingredients
Complete mutually fusion, therefore to reach design effect and just have to largely using expensive SBS, this is for SBS composite material
Extensive application for, higher cost；
(2) in existing technique, technical process control is complexity, needs to quantify the parameter of its production process then
It controls one by one, and the production process can't reach the performance required in design for SBS composite material；
(3) technique in the prior art and relevant preparation facilities are combined, one-stop flow line production technique is lacked, it is past
It is separated from each other, is then produced according to the process flow made, this will lead to following toward using between each process
The problem of two aspects: first, technique will be more complicated, need manually to carry out high-intensitive intervention, but also can not be timely
The addition of carry out ingredient and mixing；Secondly, can not achieve the intersection between technique for the cooperation processing between process
Cooperation needs other related equipment toward contact to cooperate and could complete relevant production process.
Summary of the invention
In order to overcome the shortcomings of that prior art, the present invention provide a kind of modified SBS composite-material formula of highly resistance folding
And its preparation process, it can effectively solve the problem of background technique proposes.

In the present invention, the main function of the interaction of each ingredient in the present embodiment is as described below:
Well known to those skilled in the art, since the polarity of SBS is small, the intensity of adhesive property and bonding cannot
Enough meet demands, therefore just must first go through and to form matrix to change the polarity of SBS, so that SBS has certain bonding
Performance and adhesion strength.In the present invention, SBS is formed by latex by emulsification, then passes through additive and crosslinked at low temperature agent
The whip modified effect of equal materials, so that each component is swollen in the star-like reticular structure of SBS latex, thus the composite wood formed
The inierpeneirating network structure of material can effectively improve the flexibility and brittleness problems of existing SBS composite material, improve SBS composite wood
The fracture resistance of material.
In addition, netted traction-resistant fibre forms fine and close stacked structure during mixing, to be formed nondirectional

With.
In the present invention, as shown in Figure 1, additionally providing a kind of preparation process of highly resistance folding SBS composite material, including it is as follows
Step:
Step 100, swelling add natural rubber, polypropylene, haloflex according to quality proportioning in pressure reaction still
Heat is until be in molten condition, and continue heat preservation and obtain matrix.
Swelling is high molecular polymer the phenomenon that volume expands in a solvent, due to high molecular relative molecular mass
Greatly and there is polydispersity, molecular shape has the different type of linear, branching and crosslinking, and aggregated structure has crystalline state and non-knot
The types such as crystalline substance, therefore, high molecular dissolution phenomena are more much more complex than small molecule compound.
The phenomenon that swelling refers to that solvent molecule diffuses into inside macromolecule, makes its volume expansion.Swelling is macromolecule material
Expect that peculiar phenomenon, reason are that solvent molecule differs greatly with coil dimension, molecular motion velocities differ greatly, solvent
Molecular diffusion rates are very fast, and diffusion of the macromolecule into solvent is slow.It therefore, is that solvent molecule seeps first when macromolecule dissolution
It penetrates into inside high molecular material, increases its volume, that is, be swollen.This stone lion weaving in, polypropylene with solvent molecule not
It is disconnected to penetrate into natural rubber and haloflex, while the small molecule material in high molecular material can also interpenetrate, from
And a complicated process for interpenetrating and tangling is formed, it is convenient for forming netted or island structure first by swelling process
Basic structure.And with the continuous infiltration of solvent molecule, the high molecular material volume of swelling constantly increases, macromolecular chain segment fortune
Enhancing is moved, then reaches the movement of entire macromolecular chain by the coordinated movement of various economic factors of segment, macromolecular progresses into solution, is formed
Thermodynamically stable homogeneous system, i.e. dissolution phase.Molten condition is formed after dissolution, on the one hand temperature with higher, just
In the mutual fusion of other ingredients；Another aspect in the state of high temperature keep can make scattered molecule it
Between continue relative motion, form more stable reticular structure.
In step 100, the specific steps heated in pressure reaction still are as follows:
Raw material are gradually added in pressure reaction still according to the proportion for step 101；
Step 102, the air being passed through into pressure reaction still in carbon dioxide or nitrogen pressure release reaction kettle, and continue
It is passed through carbon dioxide or nitrogen and increases pressure in pressure reaction still to 2~3MPa；
Step 103 is persistently heated to pressure reaction still, and control the pressure in pressure reaction still be maintained at 2~
Between 5MPa, until matrix is obtained in molten condition in pressure reaction still, it is lasting to keep the temperature.
In the present embodiment, it is the pressure improved in device by being passed through nitrogen or carbon dioxide one side, promotes
Dissolution and mixing, still further aspect be then so that carbon dioxide or it is nitrogen gas dissolved change the polarity of solvent in a solvent, promote
Ingredient therein mutually merges.Specifically when selecting carbon dioxide as the pressure medium chemically reacted, low with viscosity,
Diffusion coefficient is big, nontoxic, non-ignitable, chemically inert advantage, can not only avoid that initiator is added in above-mentioned reaction, subtract
The introducing of impurity is lacked, has also had many advantages, such as that the reaction time is short.
Step 200 mixes the matrix after swelling with SBS according to the proportion, and shearing grinding forms after mixture high-speed stirring again
It mixes, nano organic montmorillonite, toluene, methyl methacrylate is added according to the proportion and is developed for the first time, add after primary development
Matrix after entering swelling carries out secondary development.
In this step, first by proportion addition auxiliary material, then each component is enabled to be sufficiently mixed by high-speed stirred,
And due to being high molecular material, mixed viscosity is stronger, and the simple mixing that is stirred can not reach accordingly
Mixed effect, therefore in order to reach optimal mixed effect, the effect of shearing grinding is reached by the shearing force that high-speed stirred is formed
Fruit, to promote optimal mixing, so that being mutually sufficiently mixed between each component.
In step 200, the specific steps developed twice are as follows:
First development, sequentially adds ingredient, and continue high-speed stirred and mix them thoroughly, and the temperature improved in device is straight
It to 180~200 DEG C, persistently stirs at low speed, develops 3~4h；
Ingredient is successively added on the basis of primary development in secondary development according to the proportion, is acted on first by high-speed stirred
It mixes them thoroughly, further increases the temperature in device up to 200~210 DEG C, 4~5h is developed in consecutive low temperature stirring.
In the present invention, it is acted on by development twice, swelling can be successively added into development room or by pre- place
The raw material of reason, it can raw material can be more fully mixed therein, it can be in the case where application less material
Reach estimated mixed effect.In the present embodiment, the materials such as the SBS being swollen can be enabled adequately to enter molecule
Between form reticular structure, the secondary host material that is gradually added can make it reach full growth, achieve the purpose that improve using material,
To reduce the application of expensive material.
In addition, the relationship between also needing to consider in the present invention to be swollen and is compatible, however due to having examined in the foregoing
Consider compatible situation, be formulated by improving, changes the relationship between polarity, it is therefore, anti-by improving on the basis of above-mentioned
The temperature answered promotes swelling, especially after increasing auxiliary material, since the state of auxiliary material does not reach the locating shape of swelling
State, swelling efficiency can greatly be improved by improving temperature.
Further, in order to improve the efficiency of swelling and development, be added auxiliary material or ingredient such as nano organic montmorillonite,
Before toluene, methyl methacrylate, it is necessary to pre-process to these ingredients or auxiliary material, and the normal method handled is then
It is pulverization process to be carried out to inorganic constituents, and organic principle is then carried out also to heat while pulverization process, then divides
It is not added.
Step 300, emulsion dispersion by the mixed material heating after development to 120~130 DEG C, and continue 1~2h of heat preservation, press
Lubricant and crosslinked at low temperature agent is added according to proportion, and the soap lye that emulsifier and high-temperature water are made into is added, by colloid mill by two
Person mixes overground emulsification.
In this step, the effect that crosslinked at low temperature agent is added is so that each component swells in the star-like netted of SBS latex
In structure, thus the inierpeneirating network structure of the composite material formed, and the effect of lubricant is to promote the phase between each ingredient
Mutually fusion；And the addition emulsifier and soap lye of selectivity can then help mixture quickly to be emulsified.
In step 300, the specific steps of overground emulsification are as follows:
Raw material are added in mixture according to the proportion, and soap lye are added by step 301, are kept for 120~130 DEG C
Temperature impregnates 0.5-1h；
Step 302 soaks colloid mill by 80~100 DEG C of high temperature soap lyes, and continues to pour colloid with high temperature soap lye
Mill is preheated；
Mixture after immersion is sequentially imported and carries out grinding emulsification in colloid mill, and grinds emulsification number by step 303
Not less than 3 times.
In above-mentioned steps, before formally entering overground emulsification, colloid mill is soaked by soap lye first, is soaked
Effect be two aspect: first, pre-wetting colloid mill can prevent the biggish mixture of viscosity to be bonded in colloid mill
On, but also can prevent colloid mill itself from absorbing water so that mixture is dehydrated；Second, colloid mill is preheated by soap lye,
So that colloid mill is in environment identical with mixture before life's work, avoid due to environment difference mixture being gone out
Existing crimping or other improper situations.
Step 400, mixing, by the original after netted traction-resistant fibre, ceramic fibre, nano magnesia, antioxidant and emulsification
Material, which is placed in mixer, carries out internally mix, is granulated after circulating water through pelleter.

The machinery plasticated and be kneaded to polymer material to intermittence under closed state, in mixer, material is sheared everywhere
With the effect of friction, the temperature of the materials inside made is steeply risen, and viscosity reduces, and is increased the wettability on each component surface, is made
It can be come into full contact between each component.Material is crushed in the gap of mixer inner wall by the shearing of strength, therefore, at this
It is best able to be adequately compressed mixing in step, and reticular structure is also more capable of forming by extraneous ingredient, in this step
Various other auxiliary materials are added convenient for forming island structure.After adding ingredient, the fin on closed-smelting machine rotor enables material edge
The axial movement of rotor is played the role of being stirred, and ingredient is enable to be uniformly mixed in sizing material, shears and breaks repeatedly when ingredient
Broken, mixture is iteratively produced deformation and restores deformation, and being stirred continuously for rotor nog makes ingredient be uniformly dispersed in sizing material, and
Reach certain dispersion degree.

Additive afterwards keeps original smelting temperature, is added in mixer mixes with the raw material after emulsification again, improve mixing again
Temperature improves the revolving speed of screw rod to 80~100r/min to 300~320 DEG C；
Step 403, during mixing, the temperature of control loop cooling water gradually reduces it by cooling according to gradient
Water temperature.
Each component is carrying out mixing after mixing in mixer, so that sufficiently fusion mixes between each component, so that
Each component in composite material compositions can be combined with each other, to increase the intensity and impact property of SBS composite material.
In above-mentioned steps, by multiple mixing, ingredient can be added in mixture in progressive form, thus just
In the reticular structure for forming more phases time, and under the mixing of mixer, the reticular structure of more phases time can intersect, thus
The secondary island structure for intersecting, being stacked of more phases is formed, the stability of structure can be better than reticular structure, can be more into one
