摘要:
A self-cleaning composite material comprising the following composition is disclosed: 65-80% in weight of quartz-based mineral extenders; 2-15% in weight of fine particles of silicate family, such as wollastonite, calcium silicate, cristobalite, silica (SiO2), with size lower than 0.1 mm; 5-20% of glass microspheres, with grain size lower than 212 micron; 10-25% of methacrylic syrup composed of one monomer and one polymer; photocatalytic titanium oxide (TiO2) dispersed in methacrylic syrup in weight percentage of 0.05-5% with respect to the weight of the methacrylic syrup; coupling agent to obtain anchoring of photocatalytic TiO2 to methacrylic syrup; and cross-linking monomers to obtain reticulation of methacrylic syrup.

Embodiments of the present disclosure are directed to the targeted deposition of particles below 100 microns onto a substrate such as a film, tape, adhesive, fabric, fibers or a combination thereof. The targeted deposition may be accomplished by a dual-component electro-static deposition process. In one embodiment, the substrate having at least one layer of particles thereon may be combined with a prepreg. Prepregs manufactured according to embodiments of the invention may be used to manufacture composites with more robust mechanical and strength characteristics relative to conventional composites manufactured using conventional prepregs in addition to providing improved processed performance during the manufacture of the particle-coated substrate. In another embodiment, targeted deposition may be applied directly to a composite article to achieve similar benefits.

Disclosed are coating compositions, wearlayer compositions and surface covering products which utilize wearlayer compositions. The wearlayer compositions of the present invention are capable of at once exhibiting high initial gloss values and excellent resistance to scuff, stain and gloss loss. Such wearlayer compositions are produced utilizing curable coating compositions which comprise thermoplastic polymer, from about 3% by weight to about 25% by weight of plasticizer for the thermoplastic polymer and at least about 30% by weight of reactive crosslinking agent. The weight ratio of the thermoplastic polymer to the crosslinking agent is preferably no greater than about 2:1.
