The invention relates to a wear protection layer comprising a mixture of non-uniform transparent hard material particles, which are stored in a matrix material and which comprise a Mohs hardness of at least 6 and transparent solid material particles, wherein the transparent solid material particles encompass a bi-modal grain size distribution. The invention also relates to a method for producing a wear protection layer as well as the use thereof for producing wear protection surfaces, in particular surfaces on wood fiber boards, which are provided with a a d&#xe9;cor.

Wear protection coating based on a synthetic resin matrix, method for the production thereof and use thereof

The present invention relates to temperature-treated polycrystalline porous AlObodies comprising an amount of &#x3b1; aluminum oxide of more than 97% by weight, an amount of other oxide alloying components of a total of less than 3% by weight, a macroporosity of between 5 and 30% by volume, wherein the AlObodies are composed of a plurality of AlOprimary crystals comprising a crystallite size of between 20 and 100 &#x3bc;m.

The present invention relates to sintered abrasive grit agglomerates based on aluminum oxide, having homogeneously distributed nanoscale pores in the range of 100-300 nm, with a pore volume of at least 15%. The average diameter of primary particles of the aluminum oxide primary particles is less than 5 &#x3bc;m, wherein said primary particles are connected to each other without additional adhesive agent.

Sintered abrasive grain agglomerates

An article has an anti-abrasion layer, comprising a mixture of irregular particles of hard material and round particles essentially free of cutting edges embedded in a matrix material and the use thereof for the production of anti-abrasion surfaces on wood materials, decorative paper, or wood fiber sheets printed with patterns for the production of parquet floors, floor laminates, furniture surfaces or work boards and for the production of wear-resistant surface layers on support materials made from metal, glass, ceramics, plastic concrete or other materials.

Anti abrasion layer

The invention relates to an anti-abrasion layer, comprising a mixture of irregular particles of hard material and round particles essentially free of cutting edges embedded in a matrix material and the use thereof for the production of anti-abrasion surfaces on wood materials, decorative paper, or wood fiber sheets printed with patterns for the production of parquet floors, floor laminates, furniture surfaces or work boards and for the production of wear-resistant surface layers on support materials made from metal, glass, ceramics, plastic concrete or other materials.

The invention relates to a protective layer against wear based on artificial resin. Hard particles () having a hardness of at least 6 on the Mohs scale are embedded in said layer, as are compact, round, solid particle (), which are essentially free of sharp edges and have a hardness of at least 5 on the Mohs scale. The grain size distribution of the round solid particles () begins at least with the smallest grain diameter of the hard particles () and reaches a maximum of five times the value of the largest hard particle diameter, the average grain diameter of the solid particles () being larger than the average grain diameter of the hard particles (). The hard particles and round solid particles are admixed for producing a protective layer against wear and for providing wear-resistant surfaces.
