Abstract
The invention discloses an acicular wollastonite powder composite material for nylon 6 modification and a preparation method thereof. Every 100 parts by weight of the acicular wollastonite powder composite material comprises 98-99 parts of acicular wollastonite powder, 0.1-0.6 part of chain extender, 0.2-0.8 part of antioxidant and 0.05-0.6 part of ultraviolet absorbent. The acicular wollastonite powder is natural acicular wollastonite powder subjected to coupling treatment, the chain extender is oxazolines, the antioxidant is alcohol esters, and the ultraviolet absorbent is dibenzophenones or benzotriazoles. The components above can be blended to obtain the acicular wollastonite powder composite material for nylon 6 modification. The composite material can enhance the rigidity and relative molecular weight of the nylon 6, and ensures the nylon 6 to have high toughness, high oxidation resistance and anti-photoaging performance.
Description
technical fieldthe present invention relates to a kind of modification technology of nylon, specifically relate to a kind of preparation method for modified nylon 6 acicular wollastonite powder composite material, this material is applicable to nylon 6, the polymkeric substance such as nylon 66, tetrafluoroethylene, polypropylene (PP), polyethylene, polyester, polycarbonate, polystyrene and polyolefin masterbatch, belong to macromolecular material auxiliary agent technical field.
background technologywollastonite is one of Chinese advantage nonmetal mineral resource, and the reserves of Chinese wollastonite occupy first place in the world, and accounts in recent years the more than 50% of volume of world trade always.Along with deepening continuously of wollastonite superfine grinding and crystal structure protection deep processing research, quality product improves constantly, and range of application progressively expands.But guarantee that research and the developed country of the enough fineness of product aspect also have a certain distance when pursuing high length-diameter ratio.And the needle-shaped wollastonite powder of high fineness big L/D ratio has larger using value, as for filling plastic, can improve intensity and the dimensional stability of goods.At rubber industry, be mainly the enhancement of utilizing the like fibrous that the needle crystal of wollastonite produces, to replace the strongtheners such as glass fibre, carbon fiber and asbestos that price is more expensive, wollastonite can also play the effect that improves product properties simultaneously.Filler wollastonite is tool potentiality, the highest, the fastest-rising Application Areas of added value.Modified acicular wollastonite ultrafine powder is applied to engineering plastics and makes the Main Function of filler and be: mechanical property and the ageing resistance of improving plastics; Improve the functional strength of plastics, play reinforcement, enhancement; Improve the dimensional stability of goods; Adjust the rheological property of plastics; The glass fibre that alternative price is more expensive is made filler, can partly substitute the quantity of plastics that price is high, thereby reduces goods cost.
But the consistency of wollastonite powder and superpolymer base-material is poor, thereby directly add dispersed badly, after surface treatment, can improve and the consistency of superpolymer base-material, strengthen its strengthening action, make the mechanical property of the polymer composites materials of filling better.Wollastonite reinforced nylon 6 exist toughness and rigid balancing poor, that is to say, wollastonite reinforced nylon 6 can not have high notched Izod impact strength, tensile strength and compressive strength simultaneously.Therefore, single wollastonite reinforced nylon 6 can not meet the requirement of high tenacity and high rigid material.And, in the powder-modified processing of wollastonite, although can at Polymer Industry, apply by import substitutes, composite for acicular wollastonite, comprehensively improve also deficiency of function aspects research.
summary of the inventionthe present invention is in order to make up above-mentioned technological deficiency, and a kind of acicular wollastonite powder composite material and preparation method for modified nylon 6 is provided.
To achieve these goals, technical solution of the present invention is: for the acicular wollastonite powder composite material of modified nylon 6, adopt natural acicular wollastonite grain, particle diameter is that 1500 orders are to 3000 orders, its powder structure is needle-like, length-to-diameter ratio is (15-20): 1, and undressed acicular wollastonite, after coupling agent carries out surface treatment, is connected to filling surface; The flexible chain that its other end is grown covers the surface of polymkeric substance, forms flexible interface layer; In the acicular wollastonite powder composite material that contains 100 parts of parts by weight, 98-99 part needle shape wollastonite powder, 0.1-0.6 part chainextender, the antioxidant of 0.2-0.8 part, 0.05-0.6 part UV light absorber; Described coupling agent is type siloxane or titanate ester.
The preparation method of the described acicular wollastonite powder composite material for modified nylon 6: by above-mentioned component in following ratio (mass fraction): after the raw material of needle shape wollastonite powder 98-99 part, chainextender 0.1-0.6 part, antioxidant 0.2-0.8 part, UV light absorber 0.05-0.6 part fully mixes in high mixer, can obtain for nylon-6 modification take needle shape wollastonite powder as main matrix material.
The present invention adopts natural needle-like silicon ash, in stone flour system, introduce the mechanical property that chainextender and UV light absorber have improved nylon-6 comprehensively, there is tackiness and affinity with polymkeric substance, there is lower density, can increase tensile strength and the spring rate of goods, increase the flexural strength of material, improve resistance to impact shock and surface hardness and increase; And can prevent the problem that photoaging and goods fade. can also significantly reduce the cost of product, improve product level, when matrix material not only can improve nylon 6 rigidity, can improve again nylon 6 relative molecular weights.
