The following are the raw materials of embodiment and comparative example to form list (table 1).
1 embodiment of table and comparative example raw material form parts by weight list
The low-temperature impact-resistant fiber glass reinforced polypropylene material that above-described embodiment is prepared test such as table 2:
2 performance test project of table and standard
* Izod notched impact strength carries out normal temperature environment and -30 DEG C of tests placed after 12h respectively.
* melt index is 230 DEG C, is carried out under the test condition of 2.16KG.
The test of * * falling sphere, is tested, height of the fall ball 1.3m after the plate of sample to be tested is placed 12h at -30 DEG C,
Ball weight 500g.To crack or not crack as judgment basis, do not crack as passing through.
Table 3, sample testing result
Examples 1 to 7 is adjustment acrylic resin, glass, glass compatilizer, toughener, toner and antioxidant and profit
The additive amount of lubrication prescription, as can be seen from the table, with the promotion of glass fiber content, every mechanical property all increases, but molten
Melt index to gradually decrease, when glass fiber content is greater than 30 parts, the further promotion of glass fiber content influences low temperature impact properties
Less, but more obvious for the reduction of melt index, this can generate more detrimental effect to later period injection molding.Glass
The increase of compatilizer and toughener additive amount slightly promotes mechanical property.Meanwhile the additive amount of antimony powder, antioxidant, lubricant
Increase, the influence for mechanical property is smaller.By comparison ambient temperature mechanical properties, low temperature impact properties and melt index, implement
The comprehensive performance of example 2 is more excellent.
Embodiment 2 is compared with comparative example 1, and the glass fiber content of comparative example 1 significantly reduces, and whole mechanical properties decrease is non-
Chang Xianzhu cannot be tested by low temperature falling sphere；Embodiment 2 is compared with comparative example 2, and 2 glass additional amount of comparative example is excessively high,
Normal squeeze out can not be carried out to process；For embodiment 2 compared with comparative example 3 and 4,3 glass compatilizer additional amount of comparative example is lower,
Also there is comprehensive decline in mechanical property, and this is mainly due to the compatible dosage of glass is very few, glass is dispersed in resin matrix
It is very poor with compatibility, the undesirable effect for dispersing to cause glass that can not effectively play its activeness and quietness；4 glass of comparative example is compatible
Agent additional amount is excessive, and instead of more matrix resin, one side cost is more, and another aspect comprehensive performance also will receive
It influences, a degree of decline occurs in mechanical property.It can not both be tested by low temperature falling sphere；Embodiment 2 and comparative example 5
Compare with 6,5 toughener additional amount of comparative example is too low, and the rigidity of material significantly rises, and tensile strength and bending strength are all increased
Greatly, but there is apparent decline in toughness, and room temperature and low temperature impact strength reduce all more obviously, and can not be fallen by low temperature
Ball test.6 toughener additional amount of comparative example is excessively high, then the trend opposite with comparative example 5 occurs, although having passed through low temperature falling sphere
Test, but rigidity decline is clearly, while melt index is significantly reduced.Since the toughness of toughener itself is preferable, just
Property is poor, therefore when preparing material with glass, only the toughener of appropriate level can obtain rigidity-toughness balanced
Material；Embodiment 2 is compared with comparative example 7, has replaced toner system, has been replaced with comparison by the antimony powder of embodiment 2
Obviously gliding occur in the titanium dioxide of example 7, the mechanical property of embodiment 7, and can not be tested by low temperature falling sphere.This
Mainly since the hardness of titanium dioxide itself is higher, during twin-screw extrusion processing, the comparison that can destroy glass is tight
Weight, therefore the final glass reservation length obtained in resin is shorter.
After respectively calcining embodiment 2 and comparative example 7, the glass of both observations retains length under Quadratic Finite Element, such as Fig. 2 and
Shown in Fig. 3, the length unit of measured glass is millimeter in figure.From Fig. 2 it can be observed that the reservation length of glass is relatively long,
Its average length for retaining glass is greater than 0.5mm.From Fig. 3 it can be observed that the reservation length of glass is shorter, it is flat to retain glass
Equal length is about 0.3mm.
The foregoing is a detailed description of the present invention in conjunction with specific embodiments, and it cannot be said that the present invention is specifically real
It applies and is only limitted to these explanations.For those skilled in the art to which the present invention belongs, before not departing from present inventive concept
It puts, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to the scope of protection of the invention.
