The objective of this work is to improve the structural characteristics of hollow glass microsphere filled epoxy syntactic foam composites with little voids content and improved hollow glass microsphere dispersion in the composite.

A modified degassing technique has been introduced during resin casting process of the hollow glass microsphere filled syntactic foam composites. The effect of hollow glass microsphere content volume fractions (5–25%) on the degassing techniques was examined. The syntactic foam composites were characterized by analysing structural morphology using Scanning Electron Microscopy (SEM), Transmission Electron Microscopy(TEM), and density measurements (theoretical and experimental).

Less than 5% void content has been achieved in this study. This resulted in improved tensile and dynamic mechanical properties (DMA).

Reducing the weight of thermoplastics parts has been a high priority objective in various industries such as transportation, aerospace, hand-held electronics and sports and leisure. Hollow glass microspheres are currently used in a variety of lightweight automotive applications, including thermoplastics, sheet and bulk molding composites (SMC/BMC), underbody coatings (plastisols), structural foams and auto body fillers. Hollow glass microspheres are excellent strength/weight optimizers when they are used in filled polymer systems such as glass fiber, talc, and calcium carbonate filled thermoplastics. Reducing and replacing a certain percentage of these high density fillers with hollow glass microspheres results in weight reduction while significantly maintaining the original mechanical properties of the composite. Hollow glass microspheres impart several benefits to thermoplastics in addition to density reduction.

These include:

• productivity Benefits through faster cooling rates from the melt
• dimensional stability (sink and warpage elimination)
• increased stiffness (modulus) and heat distortion resistance
• reduced thermal conductivity and dielectric constant

All of these new functions and benefits can be achieved with class-a surface and with existing equipment enabling new design functions.

FIELD OF THE INVENTION

The invention relates to a composite of a hollow glass microsphere and a polymer with modifiable properties to produce enhanced products. The novel properties are produced in the composite by novel interactions of the components. The hollow glass microsphere and polymer composite materials are a unique combination of a hollow glass microsphere typically particulate components and a polymer material that optimizes the composite structure and characteristics through blending the combined polymer and hollow glass micros to 90% of the base polymer materials to achieve true composite properties.

BRIEF DESCRIPTION OF THE INVENTION

The invention relates to a composite of a hollow glass microsphere and a polymer having improved and novel properties methods of making and applications of the materials. The material of the invention is provided through a selection of non metallic, hollow glass microsphere particle specie, particle size (Ps) distribution, molecular weight, and viscoelastic character and processing conditions. The particles have a specific and novel particle morphology that cooperates with the components of the invention to provide the needed properties to the composite. The material attains adjustable chemical/physical properties through hollow glass microsphere selection and polymer selection.

DETAILED DISCUSSION OF THE INVENTION

The invention relates to novel composites made by combining a hollow glass microsphere particulate with a polymer to achieve novel physical electrical surface and viscoelastic properties. A hollow glass microsphere particulate having a particle size ranging from about 10 microns to about 1,500 microns can be used in the invention. The maximum size is such that the particle size (Ps) of the particle is less than 20% of either the least dimension or the thinnest part under stress in an end use article. Such particles can be substantially hollow and spherical.

Both thermoplastic and thermosetting resins can be used in the invention. Such resins are discussed in more detail below. In the case of thermoplastic resins, the composites are specifically formed by blending the particulate and interfacial modifier with thermoplastic and then forming the material into a finished composite. Thermosetting composites are made by combining the particulate and interfacial modifier with an uncured material and then curing the material into a finished composite.

Hollow glass microspheres, also called microballoons, are the most versatile. To the naked eye, the small, hollow spheres appear like fine powder. Ranging from 12 to 300 µm in diameter (by comparison, a human hair is approximately 75 µm in diameter), hollow glass microspheres pack a lot of functionality into a very small package.

Integrated the hollow glass microsphere into composite parts, they provide a variety of product enhancements and process improvements — including low density, improved dimensional stability, increased impact strength, smoother surface finish, greater thermal insulation, easier machinability, faster cycle times, and cost savings.

Composite manufacturers, already adept at making the most of their materials, regularly exploit these benefits — sometimes all at once.

Silane-treated hollow glass microspheres offer additional performance improvements. A silane coupling agent acts at the interface between an inorganic substrate, like hollow glass microspheres, and an organic polymer to bond, or couple, the two dissimilar materials.

Very destructive to adhesion is migration of water to the hydrophilic surface of the inorganic glass filler. Water attacks the interface, destroying the bond between polymer and filler. But a true coupling agent creates a water-resistant bond at the organic/inorganic interface. Silane coupling agents not only enhance bond strength but also prevent de-bonding at the interface during composite aging and use.

Notched Izod impact, tensile and flexural strengths and elongation at break all show much better properties when a coupling agent is applied to the microsphere filler. In general, notched Izod and tensile strength improve by about 40% when comparing silane-treated and untreated hollow glass microspheres. In addition, silane treatment slightly enhances the density reduction obtainable with microspheres, because the silane provides a lubricious surface layer that reduces microsphere breakage during compounding.

Adding silane treatment further increases the advantages of the newest, strongest microspheres. The most significant property improvement is in elongation at break. Here, there is almost 300% improvement from 35% elongation at break for silane-treated S60HS microspheres to 100% for silane-treated iM30K additives.

White roof coatings have existed in hot countries for a long time. These coatings help to reflect solar energy back into the atmosphere, rather than heating up the building. To achieve this white finish, pigments and fillers like titanium dioxide and calcium carbonate are used.

This article demonstrates that, with the use of hollow glass microspheres in a coating, one can achieve a high level of total solar reflection with the dry film. This helps to reduce the need for energy-intensive cooling systems.

It is worth noting that there are many coating applications possible with this technology and that it is not just restricted to improving the energy efficiency of buildings. Other examples that would benefit from the use of solar heat reflective coatings include caravans, mobile homes, cold storage distribution centres, refrigerated vehicles, oil and gas storage tanks, cryogenic tanks and tankers, and deck coatings.

Total solar emission is shown in the spectrum below. It comprises UV, visible and IR radiation – the latter responsible for heating. In this article, we will show that hollow glass microspheres offer an excellent level of reflection in both the visible and IR regions of the spectrum.
