Abstract
The invention discloses a polystyrene brittle modified plastic. The polystyrene brittle modified plastic is prepared from polystyrene resin, rubber and additives, wherein the additives are a filler, a stabilizer, a coupling agent and an antioxidant, the rubber is butadiene styrene rubber and butadiene rubber, the filler is silica, the stabilizer is barium stearate, the coupling agent is vinyl triethoxy silane, and the antioxidant is a phosphite antioxidant. By virtue of the mode, the invention provides the polystyrene brittle modified plastic which is good in the size stability and the rigidity, is easy in processing and coloring, is high in the product glossiness and the like; and meanwhile, with the adoption of the polystyrene brittle modified plastic, as the tenacity of the polystyrene is improved, the polystyrene brittle modified plastic is suitable for manufacturing various electric appliance parts, equipment housings, instrument parts, refrigerator linings, vessels, food packages, disposable utensils and the like.
Description
Technical field
The present invention relates to a kind of plastic formula, particularly relate to the brittlement modified plastics of a kind of polystyrene.
Background technology
By vinylbenzene, in rare gas element, temperature is controlled within the scope of 60-90 ℃, is that catalyzer carries out polymerization by dibenzoyl peroxide, can obtain transparent cake resin, is polystyrene resin, with polystyrene resin and additive synthetic polystyrene plastics.Though polystyrene surface is hard and smooth, transparency is good, strong coloring force, and lovely luster, polystyrene quality embrittlement, low, the easy mill of shock strength are drawn, easily fragmentation; While knocking, clear, easily cracked when stubborn folding, make being of limited application of polystyrene.
Summary of the invention
The technical problem that the present invention mainly solves is to provide one and has good stability of the dimension, good rigidly, is easy to the brittlement modified plastics of well behaved polystyrene such as processing, goods glossiness are high, easy coloring.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of polystyrene brittlement modified plastics, comprise: polystyrene resin, rubber and additive, describedly add agent and add and comprise weighting agent, stablizer, coupling agent and antioxidant, described rubber is styrene-butadiene rubber(SBR), cis-1,4-polybutadiene rubber, and described weighting agent is silicon-dioxide, and described stablizer is barium stearate, described coupling agent is vinyltriethoxysilane, and described antioxidant is that phosphorous acid esters are anti-.
In a preferred embodiment of the present invention, described rubber is styrene-butadiene rubber(SBR).
In a preferred embodiment of the present invention, the each composition of the brittlement modified plastic formula of described polystyrene accounts for weight percent and is: polystyrene resin 80% ~ 84%, butylbenzene rubber account for 10% ~ 12%, silicon-dioxide 2% ~ 5%, barium stearate 1% ~ 4%, vinyltriethoxysilane 1.5% ~ 2.3%, phosphorous acid ester 1.2% ~ 1.8%.
In a preferred embodiment of the present invention, the shared weight percent of the each composition of the brittlement modified plastic formula of described polystyrene is: polystyrene resin 82%, butylbenzene rubber account for 11.5%, silicon-dioxide 3.5%, barium stearate 2%, vinyltriethoxysilane 1.5%, phosphorous acid ester 1.5%.
The invention has the beneficial effects as follows: the invention provides the brittlement modified plastics of a kind of polystyrene, good stability of the dimension, good rigidly, be easy to processing, high, the easy coloring of goods glossiness etc., improve the toughness of polystyrene plastic simultaneously, be suitable for manufacturing various electric partss, equipment case, Meter Parts, refrigerator lining, container, food product pack and disposable utensil etc.
Embodiment
Below preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
The invention provides the brittlement modified plastics of a kind of polystyrene, comprise: polystyrene resin, rubber and additive, describedly add agent and add and comprise weighting agent, stablizer, coupling agent and antioxidant, described rubber is styrene-butadiene rubber(SBR), cis-1,4-polybutadiene rubber, described weighting agent is silicon-dioxide, described stablizer is barium stearate, and described coupling agent is vinyltriethoxysilane, and described antioxidant is that phosphorous acid esters are anti-.
Be different from prior art, in one embodiment, described rubber is styrene-butadiene rubber(SBR).
Be different from prior art, in one embodiment, the each composition of the brittlement modified plastic formula of described polystyrene accounts for weight percent and is: polystyrene resin 80% ~ 84%, butylbenzene rubber account for 10% ~ 12%, silicon-dioxide 2% ~ 5%, barium stearate 1% ~ 4%, vinyltriethoxysilane 1.5% ~ 2.3%, phosphorous acid ester 1.2% ~ 1.8%.
Be different from prior art, in one embodiment, the shared weight percent of the each composition of the brittlement modified plastic formula of described polystyrene is: polystyrene resin 82%, butylbenzene rubber account for 11.5%, silicon-dioxide 3.5%, barium stearate 2%, vinyltriethoxysilane 1.5%, phosphorous acid ester 1.5%.
The brittlement modified plastics of a kind of polystyrene provided by the invention changed common polyvinyl chloride easily cracked, adopt polystyrene and rubber to prepare in proportion, add other additives, greatly increase polystyrene good stability of the dimension, good rigidly, be easy to processing, high, the easy coloring of goods glossiness etc., improve the toughness of polystyrene simultaneously, be suitable for manufacturing various electric partss, equipment case, Meter Parts, refrigerator lining, container, food product pack and disposable utensil etc.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
