Description
Technical field
The present invention relates to a kind of polystyrol foam materials and preparation method thereof that flexibility is hydrophilic, specifically, being related to one
Kind is obtained by the component regulation of heterogeneous system has the flexible preparation method with hydrophily polystyrol foam material, belongs to
The preparation of plastic foam material and performance study.
Background technique
Foamed plastics is a kind of high molecular material formed in solid plastic by bulk gas micropore dispersion, has matter
Gently, the characteristics such as heat-insulated, sound-absorbing, damping, and dielectric properties are better than matrix resin, have many uses.Almost various plastics can be prepared
At foamed plastics.The structure of abscess has great influence to the performance of foamed plastics, under normal circumstances, the power of closed cell foamed plastic
Intensity is higher, and water imbibition is small；And the duct of open cell foamed plastic is intertwined, be to air and liquid it is permeable, generally
Softer, density is lighter, is mainly used for moisture absorption sponge, sound insulation, antidetonation etc..It uses General Purpose Polystyrenre for raw material, is squeezing
Process mesohigh injection foaming agent, can after unexpected pressure release, foaming, cooling, sizing, traction at mouth mold after die head squeezes out out
It is wound into the polystyrene foam sheet of epidermis closed pore internal openings, which can be made into disposable after vacuum suction moulding
The series packages products such as mess-tin, aquatic products disk, and be widely used in food, fruit packaging etc.；Raw meat is held in supermarket, raw fish etc.
Food service tray is exactly this polystyrene foam plastics preparation.
The antistaling cabinet of supermarket, when placing raw meat using the pallet of expanded polystyrene (EPS), typical temperature is being placed at 2~4 degree
In the process, the watery blood come is oozed out in raw meat, can directly be dropped down in the bottom of pallet, since expanded polystyrene (EPS) is hydrophobic material,
Contact angle with water belongs to super-hydrophobic scope at 90 ° or more；Watery blood, which is dispersed in tray bottom with big droplet-like, does not have raw meat to connect
The position of touching will not be cast dispersion automatically, influence appearance, also reduce the exterior quality of raw meat；In addition, due to polyphenyl second
The glass transition temperature of alkene is higher than room temperature, and the flexibility of expanded polystyrene (EPS) is insufficient, when bending deformation amplitude is big, is easy to happen
Brittle fracture.For the polystyrene foam sheet of the epidermis closed pore internal openings using extrusion foaming preparation, it is prepared into
When pallet, a certain number of holes are stabbed out on surface on it, as long as its surface has hydrophily, contact with its surface a small amount of
Watery blood can be cast, and by the hole of upper surface, into internal open celled foam, and will not be seeped from the bottom of pallet
Out.How to ensure while being used as raw meat placement tray function of polystyrene foam plastics, is making ooze out to come in raw meat to lack
The watery blood of amount can in, the polystyrene foam pallet that is cast and eventually penetrates internal openings evenly dispersed in the bottom of pallet,
The flexibility for improving polymerizing styrene foam pallet simultaneously, becomes current problem.
The present invention provides a kind of new technical solution, for the foamed plastic of polystyrene substrate, by multiphase body
The component of system regulates and controls, and prepares the polystyrol foam material with flexible and hydrophilicity.
Summary of the invention
The present invention is directed in the application of current polystyrene foam pallet, due to the blood for the raw meat exudation placed on pallet
Water can not uniformly be cast in tray bottom and penetrate into inside open celled foam and polystyrene foam pallet flexibility is insufficient at present
The problem of, it is prepared for a kind of flexible, hydrophilic polystyrol foam material, further developed the product product of foamed plastics pallet
Grade, product have significant flexible and hydrophily.
The present invention provides a kind of polystyrol foam materials and preparation method thereof that flexibility is hydrophilic, including following order to walk
It is rapid:
(1) by melt blending technique, in 165 DEG C of high-temperature mixer, by polystyrene and SBS thermoplastic elastomer (TPE)
It is uniformly mixed；
(2) water-absorbent material is added in step (1) mixture obtained, continues melting mixing to uniform, later from mixed
Material is taken out in clutch, is cooled to room temperature and is crushed.
Wherein, as follows by weight: polystyrene 87~92；SBS thermoplastic elastomer (TPE) 5~8；Water-absorbent material
3~5.The water-absorbent material is one of montmorillonite, soluble starch, polyvinyl alcohol or a variety of.
In the above technical solution, polystyrene is the basis material of flexible hydrophilic polystyrol foam material, also
It is the continuous phase of product；And SBS thermoplastic elastomer (TPE), water-absorbent material etc. become the dispersion of product then during melt blending
Phase, and multiphase compound system is together constituted with matrix.SBS thermoplastic elastomer (TPE) is using polystyrene as end segment, with poly- fourth
Diene is the linear block copolymers of intermediate elastic block；Polystyrene chain segment in SBS assigns its good processing fluidity
Can, and polybutadiene segments then assign its good rubber high resiliency.When the compound system of SBS and polystyrene melt altogether
When mixed, due to only having certain compatibility between SBS and polystyrene, during melt blending, the two cannot reach
To the dispersion level of molecular level, final SBS can only be scattered in polystyrene matrix with dispersed phase；On the other hand, certainly due to SBS
As thermoplastic elastomer (TPE), there is good processing fluidity, thus in melting process, under shearing force, SBS can be with
The lesser dispersed phase of size is formed in polystyrene matrix.It is deposited with SBS dispersed phase in the foamed plastic of polystyrene substrate
Good toughening effect can be being played to polystyrene matrix, and thus impart the certain flexibility of compound system.Body
The presence of water-absorbent material in system, effectively reduce heterogeneous system surface and water contact angle, and it is hydrophilic that hydrophobic surface, which is improved,
Surface；The water-absorbent materials such as montmorillonite, soluble starch, the polyvinyl alcohol of selection are stablized during extrusion foaming, not only may be used
To impart the surface hydrophilic behavior of product, and it can satisfy the hygienic requirements of expanded polystyrene (EPS) food service tray, and
Use process will not generate apparent mutually migration, while assigning article hydrophilic, it is ensured that the normal function of pallet.It needs
, it is noted that polyacrylamide is as water-absorbent material, and although absorption speed is fast, residual monomer acrylamide pair in its polymer
Human body is harmful, therefore does not use；In addition, although crosslinking sodium polyacrylate has very high water absorption rate, due in product
In be easy to happen and mutually migrate, and be exposed to product surface, be not also used.
Compared with prior art, the present invention with significant good effect and advance: the hydrophilic polyphenyl of flexibility of the invention
The introducing of appropriate SBS thermoplastic elastomer (TPE) and water-absorbent material in ethylene foamed material, impart compound system it is good flexible and
Good hydrophilicity.
The hydrophilic polystyrol foam material of flexibility produced by the present invention can be used for putting for the raw meat class that supermarket has watery blood to ooze out
Tray.
