Implant to be implanted in bone tissue or in bone tissue supplemented with bone substitute material

An implant (1) to be implanted in bone tissue, e.g. a dental implant or an implant for an orthopedic application, comprises surface regions (4) of a first type which have e.g. osseo-integrative, inflammation-inhibiting, infection-combating and/or growth-promoting properties, and surface regions (8) of a second type which consist of a material being liquefiable by mechanical oscillation. The implant is positioned in an opening of e.g. a jawbone and then mechanical oscillations, e.g. ultrasound is applied to it while it is pressed against the bone. The liquefiable material is such liquefied at least partly and is pressed into unevennesses and pores of the surrounding bone tissue where after resolidification it forms a positive-fit connection between the implant and the bone tissue. The surface regions of the two types are arranged and dimensioned such that, during implantation, the liquefied material does not flow or flows only to a clinically irrelevant degree over the surface regions of the first type such enabling the biologically integrative properties of these surface regions to start acting directly after implantation. The implant achieves with the help of the named positive fit a very good (primary) stability, i.e. it can be loaded immediately after implantation. By this, negative effects of non-loading are prevented and relative movements between implant and bone tissue are reduced to physiological measures and therefore have an osseo-integration promoting effect.

Surface modifying method of hollow glass beads and flame-retardant application thereof

The invention relates to a surface modifying method of hollow glass beads and a flame-retardant application thereof. The surface modifying method of the hollow glass beads comprises the following steps: (1) performing ultrasonic washing of the hollow glass beads by using a sodium hydroxide solution; (2) repeatedly washing the hollow glass beads obtained in the step (1) with deionized water and absolute ethyl alcohol respectively, and drying; and (3) dissolving the treated hollow glass beads in a mixed solution of ethanol and deionized water, and performing reflux, heating and stirring; in the heating process, dropwise adding a solution for obtaining a coating, and then adding the sodium hydroxide solution while keeping a neutral environment; and stirring for 5h, performing suction filtration and drying. In the invention, the modified hollow glass beads are adopted as a flame retardant to prepare a flame-retardant thermoplastic polyurethane composite; cone calorimeter experiments indicate that the parameters of the composite such as heat release rate, total heat release, smoke generation rate and smoke factor are remarkably reduced while the residual mass of carbon residues is greatly increased.

Method of modifying hollow glass microbeads with ionic liquid and flame-retarding thermoplastic polyurethane elastomer with the modified hollow glass microbeads as flame retardant

The invention discloses a method of modifying hollow glass microbeads with an ionic liquid and a flame-retarding thermoplastic polyurethane elastomer with the modified hollow glass microbeads as a flame retardant. The method includes the steps of: 1) treating the hollow glass microbeads with a hydrochloric acid solution; 2) after the acid treatment, repeatedly washing and drying the hollow glass microbeads; 3) activating the hollow glass microbeads, adding a silane coupling agent, and performing mechanical stirring reflux; 4) stopping the reaction and cooling the reaction product to room temperature, and performing suction filtration with acetonitrile, ethanol and deionized water and drying the reaction product; 5) adding the ionic liquid to the silanized hollow glass microbeads and performing mechanical stirring reflux; 6) stopping the reaction and cooling the reaction product to room temperature, performing suction filtration successively with ethanol, a mixed solution of ethanol and deionized water, and ethanol, and drying the reaction product. By means of the hollow glass microbeads modified with the ionic liquid as the flame retardant for preparing flame-retarding thermoplastic polyurethane (TPU) elastomer, not only is oxygen index of the composite material improved, but also the vertical combustion performance, which reflects melt-dripping resistance, is improved, so that heat release rate is reduced and smoke is significantly inhibited.
