Abstract
The invention discloses a high-performance mixed enhanced filler, which is prepared from glass fibres and silica micropowder, wherein the percentage by mass of the glass fibres is 50-70%; the percentage by mass of the silica micropowder is 30-50%; the lengths of the glass fibres are 2-5 mm, the diameters of the glass fibres are 8-15 mu m, and the mass content of SiO2 in the glass fibres is 50-60%; and the granularities of the silica micropowder are 5-30 mu m, and the mass content of SiO2 in the silica micropowder is greater than 98%. The invention further provides a preparation method for the filler aforementioned. The filler disclosed by the invention is moderate in length-diameter ratio, wide in granularity distribution, good in mobility, good in enhancing effect, excellent in dimensional stability and electrical performance, lowed in shrinking percentage, and reduced in warping deformation. The enhanced filler is used in a composite material for improving the rigidity, the dimensional stability, the impact strength, the crack resistance and the wear resistance of products, and for improving the electrical performance of the composite material simultaneously.
Description
Technical field
The present invention relates to a kind of filler, particularly a kind of high performance mixing enhancement type filler; The invention still further relates to the preparation method of this high performance mixing enhancement type filler.
Background technology
General enhancement type filler has filamentary structure such as glass fibre, wollastonite, basalt fibre etc., can improve intensity and the rigidity of matrix material, but along with the increase toughness of consumption can descend.This is because the glass fibre fasciculation, fibrous by more than 200 of every chopped strand, and convergency is good, disperses inhomogeneous causing in composite system.And excessive, the narrower particle size distribution of length-to-diameter ratio such as milled glass fiber, wollastonite, be not that homogeneous phase distributes completely in system, flowing property is relatively poor, can not form more effective and more large-area combination with system, impacting vector can not transmit in larger long-range scope, and average stress distributes effectively, therefore makes easily crack propagation, cause the impact property decline of system and because selected Processes and apparatus causes magnetic separation thing impurity more, reduced the electrical property of matrix material.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, provides that a kind of length-to-diameter ratio is moderate, size-grade distribution is wide, good fluidity, and excellent performance has reduced shrinking percentage, has reduced the high performance mixing enhancement type filler of buckling deformation.
Another technical problem to be solved by this invention has provided a kind of preparation method of above-mentioned high performance mixing enhancement type filler.
Technical problem to be solved by this invention is to realize by following technical scheme.The present invention is a kind of high performance mixing enhancement type filler, and be characterized in that its step is as follows: this filler is made by glass fibre and silicon powder; Wherein: the mass percent of glass fibre is 50～70%; The mass percent of silicon powder is 30～50%; The length of described glass fibre is 2～5mm, and diameter is 8～15um, SiO in the glass fibre
2Mass content 50-60%; The granularity of silicon powder is 5～30um, SiO in the silicon powder
2Mass content greater than 98%.
In the high performance mixing enhancement type filler of the present invention, described fiberglass surfacing can also be coated with the material layer of one or more compositions in one deck vinyl silanes, aminosilane, the methacryloxypropyl silane.Can improve strengthening the property of product through this surface treatment.
Technical problem to be solved by this invention can also further realize by following technical scheme.The present invention also provides a kind of preparation method of as the described high performance mixing enhancement type filler of above technical scheme, be characterized in, the steps include: with glass fibre, silicon powder according to described mass percent join in the ball mill in addition broken, grind, form mixture, screening namely gets the enhancement type filler.
Among the preparation method of above-described mixing enhancement type filler: this ball mill is preferably made grinding medium with alumina balls, diameter is that the grinding medium mass ratio of 20mm, 30mm, 40mm is preferably 4:4:2, the ball mill frequency is 40～45Hz, and milling time is 15～20h.
Among the preparation method of above-described mixing enhancement type filler: a kind of or 2 kinds in the grinding medium preferential oxidation aluminium abrading-ball of described ball mill, the zirconium oxide balls.
Among the preparation method of above-described mixing enhancement type filler: preferably use ultrasonic vibrating screen or jump-ball vibratory screening apparatus equipment during screening.
Compared with prior art, beneficial effect of the present invention is as follows: it is moderate that enhancement type mixed fillers of the present invention not only has length-to-diameter ratio, and size-grade distribution is wide, good fluidity, and its reinforced effects is good, dimensional stability, electrical property is excellent, has reduced shrinking percentage,, reduced buckling deformation.The inventive method is produced and has been improved production efficiency, and the glass fibre size-grade distribution of producing is wide, length-to-diameter ratio is moderate.In matrix material, use this enhancement type filler, improve rigidity, dimensional stability and the impact strength of goods, and at aspects such as the splitting resistance of goods and wear resistancies good effect is arranged, improved simultaneously the electrical property of matrix material.
