Abstract
The invention discloses a polypropylene material and a preparation method thereof, belonging to the technical field of high polymer materials. The polypropylene material is realized by compounding polypropylene with a high melt flow index with auxiliaries such as compound glass fiber outleakage preventers, a flexibilizer, a compatilizer, glass fiber chopped strands and nano silica. According to the polypropylene material disclosed by the invention, the glass fiber outleakage preventer 1 and the glass fiber outleakage preventer 2 are compounded, so that a glass fiber outleakage condition on a large part can be effectively lowered by starting from a mechanism of improving compatibility of the glass fiber and the polypropylene resin and a glass fiber leakage phenomenon during molding, and the appearance of the polypropylene material is improved.
Description
[technical field]
The present invention relates to a kind of polypropylene material and preparation method thereof, belong to technical field of polymer materials.
[background technology]
Polypropylene is a kind of semi-crystalline polymer, is one of maximum thermoplastics of consumption.Polypropylene has lower density, good comprehensive mechanical property, excellent flexural fatigue resistance, the advantages such as excellent chemical stability and electrical property.This makes polypropylene be applied in the industrial circles such as automobile, electronics, electrical equipment, furniture, building materials widely.
In order to improve the performances such as polyacrylic mechanical property, dimensional stability, thermotolerance, expanding polyacrylic use range further, usually using glass fibre to carry out enhancing modified to it.But glass fibre is inorganics, acrylic resin is organism.Both is intermediate polarity differs greatly, and due to the principle of similar compatibility, between glass fibre and acrylic resin, consistency is very poor.While Reinforced Polypropylene material, also bring glass and to leak outside the problem of (usually also claim floating fine).Which has limited the application of glass fiber reinforced polypropylene material in the higher field of appearance requirement.
The anti-glass of existing glass fibre reinforcement leaks outside the patent of invention of technology, mainly concentrates in polymeric amide and polyester material, in polypropylene material seldom.And leak outside in the polypropylene material patent of invention of technology at these few anti-glasses that relate to, and technological line mainly adds single auxiliary agent, as calcium sulfate crystal whiskers, and zinc oxide master batch, elastomerics, modification EBS.In actual industrial production, use the glass of the single auxiliary agent phenomenon that leaks outside still obvious, be difficult to accept.
[summary of the invention]
The object of the invention is to overcome the deficiencies in the prior art, provide one effectively to improve glass and leak outside, make product appearance high-quality, ensure the polypropylene material of product excellent mechanical performances simultaneously.
Another object of the present invention is to provide a kind of preparation method of above-mentioned polypropylene material.
The present invention to achieve these goals, by the following technical solutions:
A kind of polypropylene material, is characterized in that comprising following weight percent composition:
Polyacrylic melt flow index in the present invention is 25-500g/10min, is preferably one or both in homo-polypropylene and Co-polypropylene.
Toughner in the present invention is the one in C2C8 type ethylene copolymer, C2C4 type ethylene copolymer and ethylene-propylene-diene terpolymer.
Compatilizer in the present invention is a kind of and polypropylene grafted graftomer obtained in toxilic acid, maleic anhydride, glycidyl methacrylate, vinylformic acid, silane, and percentage of grafting is 0.3 ~ 1.5%.
Short glass fiber precursor in the present invention is through the alkali free glass fibre chopped strand of surface-coated silylation treating compound, and chopped length is 3 ~ 6mm, and Fibre diameter is 8 ~ 20 μm.
The agent that leaks outside of anti-glass in the present invention is that leak outside agent 1 and anti-glass of anti-glass leaks outside the mixture of agent 2.The agent 1 that leaks outside of anti-glass is the modified a kind of BAB type multipolymer obtained of ethylene bis-fatty acid amides, and the agent 2 that leaks outside of anti-glass are fusing points is 60 ~ 130 DEG C, and relative molecular weight is the olefin polymer of 500 ~ 5000.
Nano silicon particle diameter in the present invention is preferably 20 ~ 100nm.
Coupling agent in the present invention is silane coupling agent.
Oxidation inhibitor in the present invention can select conventional Hinered phenols antioxidant and the composite use of monothioester kind antioxidant.For the ease of processing, the present invention also can select to add appropriate processing aid.
In the present invention, the agent 1 that leaks outside of anti-glass is the BAB type multipolymer obtained by modification by ethylene bis-fatty acid amides, the polar group of its polar groups and glass and compatilizer forms similar anchoring node, improve consistency, promote glass fibre dispersion, and aliphatic chain forms lubricant film outside the anchoring node of glass, prevent glass from leaking outside; The agent 2 that leaks outside of anti-glass are a kind of fusing points is 60 ~ 130 DEG C, relative molecular weight is the polymkeric substance of 500 ~ 5000, in shaping process of cooling, after the cooling of acrylic resin molecular chain is freezed, still can infiltrate the glass fibre of article surface, extend the time that bath surface fluidised bed is freezed by colder die face, prevent glass fibre to be condensate in surface, produce glass and leak outside.
The nano silicon that the present invention adds has tridimensional network, serves as the Stress transmit point of glass fibre in the middle of the moulding process, breaks up dispersing glass fibers, promotes the infiltration of glass fibre, thus plays and prevent the glass effect of leaking outside.
The present invention adopts the polypropylene of high flowing to carry out modification, improves material filling ability, alleviates the adhesion of cold die face to glass, thus improves glass and to leak outside phenomenon.
The present invention also can add other auxiliary agents and improve product correlated performance further.
Preparation method of the present invention is: polypropylene, toughner, compatilizer, anti-glass are leaked outside agent, nano silicon and oxidation inhibitor after high-speed mixer and mixing is even, twin screw extruder is added by opening for feed, short glass fiber precursor adds twin screw extruder by side spout, coupling agent pumps into twin screw extruder by microprocessor pump drive, at screw speed 180 ~ 500r/min, extruding pelletization under temperature 170 ~ 220 DEG C of conditions.
The present invention, compared to prior art, has the following advantages:
The present invention selects leak outside agent 1 and anti-glass of anti-glass to leak outside agent 2 compound use, from improve glass fibre and acrylic resin consistency and shaping time glass to leak outside phenomenon generation mechanism, the large-scale article surface glass of effective reduction leaks outside the appearance effect of situation, improving product.
[embodiment]
Below in conjunction with specific embodiment, the invention will be further described:
The proportioning of embodiment 1-8 is shown in Table 1:
Table 1:
Testing method and the performance of embodiment of the present invention 1-8 are as shown in table 2:
Table 2:
As can be seen from Table 2, product prepared by the present invention has good mechanical strength and mobility, and substantially improve the situation that product glass leaks outside, further, anti-glass agent 1 and anti-glass the composite of agent 2 that leak outside that leak outside will to leak outside the good leak-proof effect of agent 2 by leak outside agent 1 or anti-glass of the anti-glass of more single use.
