Abstract
A modified plastic comprises 60-70% of linear low-density polystyrene, 4-8% of silane, 10-20% of an anti-oxidation master batch and 6-12% of assistant agents, and the assistant agents comprise a dispersant, a plasticizer, an agent and an adhesive. The anti-oxidation master batch is a PE composite anti-oxidation master batch. The agent is added to polystyrene in the formula of the modified plastic in order to make the polystyrene plastic be flexible and be difficult to break and increase the mechanical strength of the polystyrene plastic.
Description
Technical field
The present invention relates to industrial chemicals field, the present invention relates to a kind of modified polystyrene plastic especially.
Technical background
Polystyrene refers to by styrene monomer through free radical polycondensation reaction synthetic polymer, it it is a kind of water white thermoplastic, there is the glass transition temperature higher than 100° centigrade, therefore it is usually utilized to make the various disposable container needing to bear water temperature, and disposable foam food boxes etc..
Owing to polystyrene plastics belongs to difficult inactive surfaces material, industry is fitted, need to use specialty polystyrene glue bonding.Polystyrene electrical insulating property (especially high-frequency insulation) is excellent, water white transparency, and light transmittance is only second to lucite, coloring resistance to water, and chemical stability is good, and intensity is general, but matter is crisp, is easily generated stress embrittlement.
Summary of the invention
It is an object of the invention to provide a kind of mechanical performance to do, plasticity is good, good luster plastics.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of modified plastics, including linear low density polystyrene, auxiliary addition agent, antioxygen masterbatch, described auxiliary addition agent includes dispersant, plasticizer, agent, adhesive, described linear low density polystyrene accounts for the 60-70% of Material Percentage, silane accounts for the 4-8% of Material Percentage, and antioxygen masterbatch accounts for the 10-20% of Material Percentage, and auxiliary addition agent accounts for the 6-12% of Material Percentage.
Described dose is liquid polysulfide rubber, plasticizer is O-phthalic dibutyl ester, dispersant is three second class base phosphoric acid, adhesive is polyvinyl acetate, described Molten sulphur rubber accounts for 13%-17%, O-phthalic dibutyl ester accounts for 3.3-5.8%, and three second class base phosphoric acid account for 3.1-5.7%, and polyvinyl acetate accounts for 2.6-4.5%
Described antioxygen masterbatch is that PE is combined antioxygen masterbatch.
The beneficial effects of the present invention is: the armor agent in polystyrene of the formula of the present invention, polystyrene plastics can be made to become pliable and tough not easy fracture, increase the mechanical strength of polystyrene plastics, additionally, plasticizer, dispersant can increase polystyrene plastics and gloss, adhesive can improve the viscosity of polystyrene plastics, is allowed to convenient and other products with adhesive.
Detailed description of the invention
A kind of modified polystyrene plastic formula of offer of the present invention, including linear low density polystyrene, auxiliary addition agent, antioxygen masterbatch, described auxiliary addition agent includes dispersant, plasticizer, agent, adhesive, described linear low density polystyrene accounts for the 60-70% of Material Percentage, silane accounts for the 4-8% of Material Percentage, antioxygen masterbatch accounts for the 10-20% of Material Percentage, and auxiliary addition agent accounts for the 6-12% of Material Percentage.
Described dose is liquid polysulfide rubber, plasticizer is O-phthalic dibutyl ester, dispersant is three second class base phosphoric acid, adhesive is polyvinyl acetate, described Molten sulphur rubber accounts for 13%-17%, O-phthalic dibutyl ester accounts for 3.3-5.8%, and three second class base phosphoric acid account for 3.1-5.7%, and polyvinyl acetate accounts for 2.6-4.5%
Described antioxygen masterbatch is that PE is combined antioxygen masterbatch.
Further, in the formula of described polystyrene, the weight proportion scope of each composition is that polystyrene accounts for 70%, and Molten sulphur rubber accounts for 16%, and neck phthalic acid dibutyl ester accounts for 4.6%, and triethyl group hexyl phosphoric acid accounts for 3.5%, and polyvinyl acetate accounts for 3.9%.
Further, in the formula of described polystyrene, the weight proportion scope of each composition is that base styrene accounts for 60%, and silane accounts for 12%, and PE is combined antioxygen masterbatch and accounts for 20%, and plasticizer accounts for 8%.
The beneficial effects of the present invention is: the armor agent in polystyrene of the formula of the present invention, polystyrene plastics can be made to become pliable and tough not easy fracture, increase the mechanical strength of polystyrene plastics, additionally, plasticizer, dispersant can increase polystyrene plastics and gloss, adhesive can improve the viscosity of polystyrene plastics, is allowed to convenient and other products with adhesive.
