Abstract
The invention discloses a kind of fiber glass reinforced polypropylene, the component matched by following weight is formed：Polypropylene 64.45%；Glass fibre 30%；Compatilizer 5%；Lubricant 0.5%；Titanium dioxide 0.05%.A kind of fiber glass reinforced polypropylene that the present invention obtains, it has the technical effect that：Due to adding titanium dioxide in the fiber glass reinforced polypropylene, so that the material is in process of production, it is not necessary to strengthens the shear ability of extruder screw, and can ensure effectively to moisten with resin inside glass, manufactured product smooth in appearance is beautiful, and does not influence its performance.
Description
Technical field
The invention belongs to organic material technical field, and in particular to a kind of fiber glass reinforced polypropylene.
Background technology
The polypropylene of fiberglass reinforced has high intensity, high rigidity, firm impact strength, low as a kind of general engineering plastic
The excellent properties such as density, low warpage creep properties, anti-dynamic fatigue, because its is cost-effective, are widely used in the structures such as automobile, household electrical appliances
The material such as parts, substituted metal, short glass fiber enhancing nylon.At present, fiber glass reinforced polypropylene is generally by polypropylene, glass fibers
Dimension, compatilizer and lubricant are prepared, and still, in process of production, glass is difficult to cut fiber glass reinforced polypropylene, so that
Length of Glass Fiber is long, scattered uneven, cannot effectively moisten with resin inside the glass of pencil, so exists with the glass of pencil
Stress concentration, often blocks die hole, so that a glass fine hair and broken strip round and round can be taken out of with material strip by causing at orifice exit,
Product is set to seem coarse, it is not smooth enough.In order to solve the problems, such as this, existing way is typically to strengthen cutting for extruder screw
Cut ability, but shear ability crosses conference that to shear glass broken, so as to influence end properties.
The content of the invention
In order to solve above-mentioned the deficiencies in the prior art, the present invention provides a kind of fiber glass reinforced polypropylene, can not only ensure
Properties of product, and the surface smooth and beautiful appearance of product can be made, while broken strip can be reduced and save cost.
To achieve these goals, a kind of fiber glass reinforced polypropylene designed by the present invention, the group matched by following weight
Divide and form：
The polypropylene is the mixture of copolymer polypropylene and homopolypropylene, and the weight proportion of wherein copolymer polypropylene is
50%, the weight proportion of homopolypropylene is 14.45%.
The polypropylene that the compatilizer is grafted for maleic anhydride or glycidyl acrylate, compatilizer can be carried significantly
The compatibility of high acrylic resin and glass, strengthens interfacial interaction therebetween, so as to improve the mechanical strength of material.
The lubricant is N, N '-ethylene bis stearamide, Tissuemat E, oxidized polyethylene wax, calcium stearate with it is stearic
One or more kinds of mixtures in sour zinc, the addition of lubricant can ensure that material takes off in injection molding with good
Mould.
The preparation method of the fiber glass reinforced polypropylene is compared with technology, and details are not described herein.
A kind of fiber glass reinforced polypropylene that the present invention obtains, it has the technical effect that：1st, due in the fiber glass reinforced polypropylene
In add titanium dioxide so that the material is in process of production, it is not necessary to strengthen the shear ability of extruder screw, and
It can ensure effectively to moisten with resin inside glass, manufactured product smooth in appearance is beautiful, and does not influence its performance；2nd, it is raw
The broken strip material head produced during production is few, greatly reduces loss, improves finished product output capacity；3rd, since broken strip seldom occurs, no
Need personnel to keep always and handle broken strip in board, reduce cost of labor.
Embodiment
With reference to specific embodiment, the invention will be further described.
Embodiment 1：
Raw material, copolymer polypropylene are weighed by weight ratio：50%；Homopolypropylene：14.45%；Compatilizer：5%；Lubrication
Agent：0.5%；Titanium dioxide 0.05%.Above-mentioned mixed material is added by double screw extruder feeding, and is added by side feeding
Enter the glass fibre that weight ratio is 30%, extrude and be granulated afterwards.The processing method of the glass-reinforced polypropylene compared with technology, 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.According to
It is as follows that the fiber glass reinforced polypropylene that above-mentioned weight proportion obtains by test obtains physical property measurement data：Tensile strength is
82.53MPa；Elongation is 5.66%, bending strength 115.5MPa, bending modulus 5290MPa, and notch impact strength is
10.05J/m, Rockwell intensity are 102, and heat distortion temperature is 150 DEG C.And draw the product in production process by a large number of experiments
In, one ton of product is often produced, the broken strip material strip of 3-7kg can be produced.
Comparative example 1：
Raw material, copolymer polypropylene are weighed by weight ratio：50%；Homopolypropylene：14.5%；Compatilizer：5%；Lubrication
Agent：0.5%.Above-mentioned mixed material is added by double screw extruder feeding, and it is 30% to add weight ratio by side feeding
Glass fibre, extrude and be granulated afterwards.The processing method of glass-reinforced polypropylene in comparative example 1 processes bar with embodiment 1
Part is also the same as 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.
It is tested after to product particle and to obtain physical property measurement data as follows：Tensile strength is 82.57MPa；Elongation is
5.67%, bending strength 115.63MPa, bending modulus 5296MPa, notch impact strength 10.06J/m, Rockwell intensity
For 102, heat distortion temperature is 150 DEG C.And draw the product in process of production by a large number of experiments, often produce one ton of production
Product, can produce the broken strip material strip of 50-60kg.
The fiber glass reinforced polypropylene that the fiber glass reinforced polypropylene obtained in comparative example 1 is obtained with the embodiment 1 in the present invention
Compare and understand, easy broken strip in the process in comparative example 1, and product surface is coarse；In process in embodiment 1 not
Easy broken strip, product surface relative smooth, and it was found from physical property measurement data, almost without difference in performance.
