Abstract
The invention discloses glass fiber reinforced polypropylene which comprises the following components in percentage by weight: 64.45 percent of polypropylene, 30 percent of glass fibers, 5 percent of a compatilizer, 0.5 percent of a lubricating agent and 0.05 percent of titanium dioxide. The glass fiber reinforced polypropylene disclosed by the invention has the technical effects that because the titanium dioxide is added into the glass fiber reinforced polypropylene, the shear capacity of an extruder screw does not need to be enhanced in the material production process, the interior of the glass fibers can be effectively wetted with resins, the manufactured product is smooth and attractive in surface, and the performance is not influenced.
Description
Technical field
The invention belongs to organic materials technical field, be specifically related to a kind of fiber glass reinforced polypropylene.
Background technology
The polypropylene of fiberglass reinforced is as a kind of general engineering plastic, there is the excellent properties such as high strength, high rigidity, just shock strength, low density, low warpage creep properties, anti-dynamic fatigue, because its cost performance is high, be widely used in the structural elements such as automobile, household electrical appliances, the materials such as substituted metal, short glass fiber Reinforced Nylon.At present, fiber glass reinforced polypropylene is generally prepared from by polypropylene, glass fibre, compatilizer and lubricant, but, fiber glass reinforced polypropylene in process of production, glass is difficult to cut off, so that Length of Glass Fiber is long, disperses uneven, the glass inside of pencil can not be effectively moistening with resin, there is stress concentration with the glass of pencil like this, often nib is blocked, thus cause orifice exit place can take a glass fine hair round and round and disconnected bar out of with material strip, product is made to seem coarse, smooth not.In order to address this problem, existing way normally strengthens the shear ability of extruder screw, but shear ability is crossed conference and made glass shear overbreak, thus affects end properties.
Summary of the invention
In order to solve above-mentioned the deficiencies in the prior art, the invention provides a kind of fiber glass reinforced polypropylene, not only can ensure product performance, the smooth surface of product can be made again attractive in appearance, disconnected bar can be reduced simultaneously and save cost.
To achieve these goals, a kind of fiber glass reinforced polypropylene designed by the present invention, is made up of the component of following weight proportioning:
Described polypropylene is the mixture of Co-polypropylene and homo-polypropylene, and wherein the weight proportion of Co-polypropylene is 50%, and the weight proportion of homo-polypropylene is 14.45%.
Described compatilizer is the polypropylene of maleic anhydride or glycidyl acrylate grafting, and compatilizer can increase substantially the consistency of acrylic resin and glass, strengthens interfacial interaction therebetween, thus improves the mechanical strength of material.
Described lubricant is N, N ' one or more mixture in-ethylene bis stearamide, polyethylene wax, oxidized polyethlene wax, calcium stearate and Zinic stearas, adding of lubricant can ensure that material has good release property when injection moulding.
The same prior art of preparation method of this fiber glass reinforced polypropylene, does not repeat them here.
A kind of fiber glass reinforced polypropylene that the present invention obtains, its technique effect is: 1, owing to adding titanium dioxide in this fiber glass reinforced polypropylene, thus make this material in process of production, do not need the shear ability strengthening extruder screw, and can ensure that glass inside can be effectively moistening with resin, the product smooth in appearance made is attractive in appearance, and does not affect its performance; 2, the disconnected bar stub bar produced in production process is few, greatly reduces loss, improves finished product output capacity; 3, because disconnected bar seldom occurs, do not need personnel to keep always and to break bar in board process, reduce cost of labor.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.
Embodiment 1:
Weigh raw material by weight ratio, Co-polypropylene: 50%; Homo-polypropylene: 14.45%; Compatilizer: 5%; Lubricant: 0.5%; Titanium dioxide 0.05%.Above-mentioned mixed material is added by twin screw extruder feeding, and adds by side feeding the glass fibre that weight ratio is 30%, after to extrude and granulation.The same prior art of working method of this glass-reinforced polypropylene, its processing conditions is: extrusion temperature is 180-230 DEG C, and the rotating speed of screw rod is 320r/min, and injection temperature is 190-210 DEG C.It is as follows that the fiber glass reinforced polypropylene obtained according to above-mentioned weight proportion obtains physical property measurement data through test: tensile strength is 82.53MPa; Elongation is 5.66%, and flexural strength is 115.5MPa, and modulus in flexure is 5290MPa, and notched Izod impact strength is 10.05J/m, and Rockwell intensity is 102, and heat-drawn wire is 150 DEG C.And draw this product in process of production through lot of experiments, often produce one ton of this product, the disconnected bar material strip of 3-7kg can be produced.
Comparative example 1:
Weigh raw material by weight ratio, Co-polypropylene: 50%; Homo-polypropylene: 14.5%; Compatilizer: 5%; Lubricant: 0.5%.Above-mentioned mixed material is added by twin screw extruder feeding, and adds by side feeding the glass fibre that weight ratio is 30%, after to extrude and granulation.The working method of the glass-reinforced polypropylene in comparative example 1 is with embodiment 1, and processing conditions is also with embodiment 1: extrusion temperature is 180-230 DEG C, and the rotating speed of screw rod is 320r/min, and injection temperature is 190-210 DEG C.After obtaining product particle, it to be tested and to obtain physical property measurement data as follows: tensile strength is 82.57MPa; Elongation is 5.67%, and flexural strength is 115.63MPa, and modulus in flexure is 5296MPa, and notched Izod impact strength is 10.06J/m, and Rockwell intensity is 102, and heat-drawn wire is 150 DEG C.And draw this product in process of production through lot of experiments, often produce one ton of product, the disconnected bar material strip of 50-60kg can be produced.
Known compared with the fiber glass reinforced polypropylene that the fiber glass reinforced polypropylene obtained in comparative example 1 and the embodiment 1 in the present invention obtain, easily broken bar in the course of processing in comparative example 1, and product surface is coarse; Not easily broken bar in the course of processing in embodiment 1, product surface relative smooth, and from physical property measurement data, almost as broad as long in performance.
