Description
Technical field
The present invention relates to a kind of aryl multi-arm silane coupling agent and preparation method thereof, belong to materials chemistry field.
Background technology
Coupling agent is a kind of functional compounds that can strengthen bond properties between inorganic substance and organic substance.In coupling agent molecule, contain two kinds of groups of different nature, a kind of is the group of close inorganics, hydroxyl normally, can with inorganic material surface react with; Another is close organic organic group, can with organic polymer generation physical action or chemical reaction.Therefore coupling agent is often used to improve the interface interaction between inorganics and organism, improves the bond properties at organic constituent and inorganic materials interface.
Silane coupling agent is a most important class in coupling agent, in fields such as matrix material, rubber, tackiness agent and coating, is widely used.Silane coupling agent can improve mineral filler and interlaminar resin consistency, improves composite material combination property.Silane coupling agent can also increase the cohesive strength of binding agent, sealing agent and coating, the water-fast performance such as weather-proof.In tackiness agent, add silane coupling agent can not only improve bond strength, and can also improve weather resistance and the wet and heat ageing resistant performance of tackiness agent.For example, although polyurethane adhesive has higher bounding force to many materials, its weather resistance is not ideal, adds silane coupling agent can improve its weather resistance.In addition, for polyurethane tackifier, under hot and humid condition, easily wreck, add silane coupling agent also can significantly improve its wet-hot aging performance.Silane coupling agent, for coating, can reduce the corrosion of wet environment floating coat and peeling off of paint film, improves scuff resistance and environment resistant.Silane coupling agent is used in coating also can play pigment dispersing agent, and they can be firmly bonded on various mineral dyes and filler, reduces the viscosity of coating, improves the dispersiveness of filler, thereby improves opacifying power, improves weather resistance and the scrubbability of coating.
Polyarylester, polyaramide, PAEK, polyarylsulphone, polycarbonate, resol, Polybenzoxazine, polybenzimidazole and polyphenylene oxide etc. are the important macromolecule resin materials containing aromatic nucleus of a class, in its macromolecular chain, contain strong polar group and aromatic group, this resinoid mechanical property and heat resistance are outstanding, itself can directly be used as engineering plastics, the high performance composite that can make together with filler, therefore, in industry manufacture, field of aerospace technology, there is important application prospect.Filler is widely used in resin, rubber and coating, in order to improve mechanical property and the processing characteristics of body material, and reduces costs.Filler can be powdery, cotton-shaped or fibrous material, as calcium carbonate, carbon black, white carbon black and glass fibre etc., for matrix resin, can prepare all kinds of matrix materials with superperformance.But because filling surface multi-band has hydrophilic radical, with organic resin, the consistency particularly containing between aromatic group resin is poor, affects the performance of matrix material.The goods made from it are in water surrounding or under high humidity, faint bounding force between filler and matrix resin can lose efficacy, therefore, filler is used coupling agent to carry out surface treatment conventionally, coupled dose of institute of inorganic filler surface covered, the organic group of coupling agent makes mineral filler have hydrophobic and the performance of close resin, thereby has greatly improved the consistency of filler and organic matrix, makes the matrix material of excellent performance.
Traditional silane coupling agent, as KH550, KH560 and KH570 etc., with a tri-alkoxy (methoxy or ethoxy) silane group, can be called single armed silane coupling agent.Three cross-linking set of the in use maximum generation of silica-based part of this silane coupling agent, relatively little with the clinging power of filling surface, not strong with the macromolecule resin avidity containing aromatic nucleus, limited to a certain extent the raising of the various performances of matrix material.For remedy such and insufficient, can use tackifier to increase bonding effect, but tackifier just play physically adhesive effect, limited to the bond strength contribution of reinforcing filler and interlaminar resin.
Having a kind of pair-Trimethoxy silane coupling agent of reported in literature, can produce six cross-linking set, is the twice of traditional single armed trialkoxy silane, can improve coupling agent at the bounding force (P.A.Toensmeier of interface region, Modern Plastics (1987), Vol.5,55).
CN102329336A discloses single armed and many ureido silanes of both arms coupling agent, and the adhesive aid using it as room temp solidified organo-silicone rubber (RTV) composition, can obtain room temp solidified (RTV) organopolysiloxane composition of bond properties, excellent storage stability.
US6261638 discloses a kind of " multi-functional base silane ", for preventing the composition of metallic corrosion, this " multi-functional base silane " contains two or three water-disintegrable silane groups, this patent documentation is that example illustrates that this one type of silane can improve the erosion resistance of metal in sodium chloride solution greatly with the two silica-based ethane of triethoxy of 1,2-.
But it is not the disclosed coupling agent cross-linking set of above-mentioned document is few, with matrix resin, particularly, strong with the bonding force containing aromatic group resin.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of aryl multi-arm silane, in this aryl multi-arm silane molecule, contain aryl, urea groups, amido and a plurality of water-disintegrable silane group, the functional group in silane molecule can regulate and control.When this aryl multi-arm silane is used as coupling agent treatment inorganic filler surface, except having the advantage of common silane coupling agent, can further strengthen matrix resin that mineral filler and polarity are strong and containing the bounding force of aromatic group macromolecule resin, improve the over-all properties of matrix material.
