Abstract
The invention discloses a PC thin-film material modification formula. According to the formula, 92% of PC raw material, 0.1% of flexibilizer, 5% of fire retardant, 0.5% of antioxidant, 0.4% of anti-dripping agent and 2% of black colorant are taken, wherein the fire retardant is halogen-free flame retardant of phosphorus series, the flexibilizer is an all-acrylate nucleoid anti-impact agent, the antioxidant is hindered phenol primary antioxidant, the anti-dripping agent is polytetrafluoroethylene, the black colorant is carrier-free special process carbon black with the content between 40% and 50%, and all the materials are prepared into a PC thin-film material according to a preparation process. By the adoption of the PC modification formula, heat resistance, impact resistance and surface hardness are improved on the basis of a small change in the mechanical property, thermodynamic property and the like of PC resin, and the thickness of the PC resin can be controlled within a certain range; the formula meets an RoHS instruction and expands the field of outer parts which can be used for replacing a part of injection molding parts. The formula is reasonable, fluidity is good after modification, quality is stable, and the preparation process is simple.
Description
Technical field
The present invention relates to the modification field of macromolecular material, particularly a kind of PC thin-film material modified formula.
Background technology
PC film is the abbreviation of polycarbonate film, have excellent toughness, good dimensional stability, can at-60 ~ 120 DEG C life-time service, but itself is shock-resistant and surface hardness is not good, therefore on PC basis, modification is carried out, develop shock-resistant processing and improve its surface hardness, and meeting the modified product of European Union ROSH standard, PC can be expanded to a great extent and use field.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides one and there is the good and surface hardness high characteristic PC thin-film material modified formula of good heat resistance, shock-resistance.
The present invention in order to the technical scheme solving its technical problem and adopt is: a kind of PC thin-film material modified formula, its each constituent mass degree is: PC raw material 90 ~ 95%, toughner 0.05 ~ 1.5%, fire retardant 2 ~ 5%, antioxidant 0.2 ~ 0.5%, anti-dripping agent 0.1 ~ 0.4%, black look mother 0.5 ~ 2%.
As a further improvement on the present invention, described toughner is all acrylic ester nucleoid impact modifier.
As a further improvement on the present invention, described fire retardant is halogen-free flame retardants: phosphorus system.
As a further improvement on the present invention, described antioxidant is Hinered phenols primary antioxidant.
As a further improvement on the present invention, described anti-dripping agent is tetrafluoroethylene, and black look female.
The invention has the beneficial effects as follows: modification PC provided by the invention fills a prescription and improves thermotolerance, shock-resistance and surface hardness changing on little basis the mechanical property of PC resin and thermomechanical property etc., and can by its gauge control in certain limit, this formula meets RoHS instruction, expands appearance component field and applies and replace part injection part.The present invention fills a prescription rationally, modified good fluidity, and steady quality, preparation technology is simple.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, and this embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
Embodiment 1: get PC raw material 92%, toughner 0.1%, fire retardant 5%, antioxidant 0.5%, anti-dripping agent 0.4%, black look mother 2%, fire retardant is halogen-free flame retardants: phosphorus system, toughner: all acrylic ester nucleoid impact modifier, antioxidant: Hinered phenols primary antioxidant, anti-dripping agent: tetrafluoroethylene, black look female: DNAcarrier free special process carbon black, carbon black content 50%, makes PC thin-film material by preparation technology.
Embodiment 2: get PC raw material 94%, toughner 0.2%, fire retardant 5%, antioxidant 0.2%, anti-dripping agent 0.1%, black look mother 0.5%, fire retardant is halogen-free flame retardants: phosphorus system, toughner: all acrylic ester nucleoid impact modifier, antioxidant: Hinered phenols primary antioxidant, anti-dripping agent: tetrafluoroethylene, black look female: DNAcarrier free special process carbon black, carbon black content 40%, makes PC thin-film material by preparation technology.
Above-mentioned formula is produced the thick material of 0.96mm and is toasted half an hour without distortion at 130 degree of constant temperature, can be passed through drilling machine high-speed drilling and there will not be aperture distortion and material to burn; Can not produce burr and material deformation when material punching press stamp, surface hardness can reach HB rank
PC raw material can adopt PC reclaimed materials to replace, and reclaimed materials can not have the bad phenomenon such as degradation impurity is many, controls reclaimed materials quality well, can not reduce in quality product situation, reduces product cost.
