Abstract
The invention discloses a formula of anti-dripping polypropylene. The engineering plastic contains polypropylene, filler, compatilizer, plasticizer, an antioxidant and an anti-dripping agent, wherein the polypropylene is syndiotatic polypropylene; the anti-dripping agent is polytetrafluoroethylene; the filler is carbon black; the antioxidant is thiodipropionic acid; the plasticizer is dioctyl phthalate; the antioxidant is thiodipropionic acid; and the compatilizer is styrene-maleic anhydride copolymer. By virtue of the way, according to the formula of the anti-dripping polypropylene disclosed by the invention, quantitative polytetrafluoroethylene can be added into the original polypropylene plastic; the compatilizer can be utilized to change the performances of the material, so that the characteristic that the original polypropylene with high-speed precise plasticity is easily dropped is improved.
Description
Technical field
The present invention relates to a kind of engineering plastics prescription, particularly relate to the polyacrylic prescription of a kind of anti-drippage.
Background technology
In recent years, along with developing rapidly of industrial development, polypropylene is heat-resisting, corrosion-resistant because of it, outstanding advantages such as goods used vapour sterilization are used widely in fields such as packing, transportation, household electrical appliances, automobile, offices, but in high-precision product high speed rotating molding process, though plasticity is good, use but also be difficult to reach preferably, therefore the effective head it off of the polyacrylic prescription of anti-drippage of the present invention.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of anti-drippage polypropylene formulations, can in original acrylic plastering, add certain tetrafluoroethylene, utilize the effect of compatilizer, changed the performance of material, improved the character that original polypropylene drips easily when high speed and precision plasticity.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of anti-drippage polypropylene formulations is provided, consisting of of this project plastics: contain polypropylene, weighting agent, compatilizer, softening agent, antioxidant and Antidrip agent, it is characterized in that described polypropylene is syndiotactic polypropylene, Antidrip agent is tetrafluoroethylene, softening agent is dioctyl phthalate (DOP), compatilizer is styrene-maleic anhydride copolymer, and weighting agent is carbon black, and antioxidant is the ternary antioxidant; Described Antidrip agent tetrafluoroethylene be 0.1 ~ 1%(by percentage to the quality).
In a preferred embodiment of the present invention, described compatilizer styrene-maleic anhydride copolymer be 1 ~ 5%(by percentage to the quality), polypropylene be 75%-85%(by percentage to the quality), the ternary antioxidant for the ternary antioxidant be 0.1 ~ 1%(by percentage to the quality).
In a preferred embodiment of the present invention, described Antidrip agent is that mass ratio is the tetrafluoroethylene of 10 ~ 1:1 and the compound of inclined to one side tetrafluoroethylene.
In a preferred embodiment of the present invention, described Antidrip agent tetrafluoroethylene or tetrafluoroethylene and partially the composition of the compound of tetrafluoroethylene be 0.6%(by percentage to the quality).
The invention has the beneficial effects as follows: can in original acrylic plastering, add certain tetrafluoroethylene, utilize the effect of compatilizer, improved the character that original polypropylene drips easily when high speed and precision plasticity, made in the processing of product high speed and precision to have more practicality.
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 more explicit defining.
The embodiment of the invention provides following technical scheme.
In one embodiment, a kind of anti-drippage polypropylene formulations, consisting of of this project plastics: contain polypropylene, weighting agent, compatilizer, softening agent, antioxidant and Antidrip agent, it is characterized in that described polypropylene is syndiotactic polypropylene, Antidrip agent is tetrafluoroethylene, softening agent is dioctyl phthalate (DOP), compatilizer is styrene-maleic anhydride copolymer, and weighting agent is carbon black, and antioxidant is the ternary antioxidant; Described Antidrip agent tetrafluoroethylene be 0.1 ~ 1%(by percentage to the quality).
Be different from prior art, in one embodiment, described compatilizer styrene-maleic anhydride copolymer be 1 ~ 5%(by percentage to the quality), polypropylene be 75%-85%(by percentage to the quality), the ternary antioxidant for the ternary antioxidant be 0.1 ~ 1%(by percentage to the quality), preferably, described Antidrip agent can be for for mass ratio being the tetrafluoroethylene of 10 ~ 1:1 and the compound of inclined to one side tetrafluoroethylene.
Preferably, described Antidrip agent tetrafluoroethylene or tetrafluoroethylene and partially the composition of the compound of tetrafluoroethylene be 0.6%(by percentage to the quality), in this mass percent, the required compatibilizer content of the anti-drippage of moulding can be reduced to minimum.
The present invention is by adding certain tetrafluoroethylene in original acrylic plastering, effectively improved the character that original polypropylene drips easily when high speed and precision plasticity, make in the processing of product high speed and precision to have more practicality, reached and reached more accurate effect in the time of in the course of processing, can making the processed goods moulding.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes description of the present invention to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
