Problems solved by technology

One reason is the belief that silicon oxide (SiO 2 ) should be between 65% and 85% by weight, if SiO 2 A weight percentage of less than 60-65% will greatly reduce the yield of hollow spheres

Embodiment -1

[0065] In one illustrative example, a hot melt polyamide (nylon) adhesive (HB Fuller HL6608) was used as the polymer matrix. This particular product has a viscosity of 4,175 cP at 190°C and a viscosity of 1,800 - 3,800 cP at 204°C. This product is advantageous due to its crystallization point and its ability to harden at different temperatures:

[0066]Compounded glue sticks with a loading fraction of stainless steel particles of about 0.4-0.7, especially 0.54, 0.59, 0.60, 0.63, 0.67, were interfacially modified at 0.40% by weight. Glue sticks were compounded using a 19mm laboratory twin-screw compounder at a target melting temperature of 165°C and discharged directly into cylindrical moulds. The molds are 5 / 8 inch and 1 inch in diameter and are used to produce cylinders of densified molten molding material compatible with industrial 3M glue guns. Then, the glue stick was melted in the glue gun at the temperature of 190-220℃, successfully fired into the double hook head and ...

Embodiment -2

[0069] Other polymers have been successfully processed into cylindrical glue sticks for injection molding with hot melt glue guns; namely Arkema 28-05 and much lower viscosity 18-500 products. The product is a random copolymer of ethylene and vinyl acetate. Both products were manufactured with a metal loading fraction of 0.63, the metal being stainless steel previously coated with 0.40 wt% interfacial modifier.

Embodiment -3

[0072] Evatane 18-500 was mixed with low cost iron powder (sold under the designation S-70) from Ervin Industries (Adrian, MI, USA). The iron powder was interfacially modified with 0.4 wt% interfacial modifier prior to compounding. EVA and iron powder were compounded to 5.0 g-cm in a 19mm B&P co-rotator compounder -3 The target density (63.7 volume % / 92.9 weight % metal particles) was formed into 1 inch diameter rods. This low cost formulation shows the ability to form and can be formed at lower temperatures (68°C) and can be manually pressed into cavities for added weight / ballasting. The material can be filled with a variety of products, including candlestick holder bases, freestanding paper towel holder bases, stapler bases, adhesive tape cutter bases, siren bases, and portable light bases. Due to the introduction of general ballast in articles containing cavities in which materials are placed, all products exhibited better performance due to increased weight and stability...

Abstract

The invention relates to a hot melt dispensable polymeric composite and process for making and using the composite. Particulates of adequate particle size are mixed with a polymer that exhibits low viscosities at temperatures typically provided by hot-melt glue guns to form rods that vary significantly in density from the base polymer. Novel articles can be manufactured by dispensing the composite from a glue gun into molds or by placement of the melt molding compound into preformed cavities within an end article.
