Abstract
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.
Claims12
Anti abrasion layer comprising:
- a mixture of irregular particles of hard material and round solid material particles, essentially free of cutting edges, embedded in a matrix material, wherein:
- the particles of hard material have a Mohs hardness rating of at least 6, and the solid material particles have a Mohs hardness rating of at least 3, characterized in that:
- the average particle diameter of the solid material particles is equal to or less than the average particle diameter of the particles of hard material;
- the round solid particles essentially free of cutting edges are made of a material selected from the group consisting of glass and sintered ceramic;
- and
- the ratio of round solid material particles, essentially free of cutting edges, in the embedded mixture is 10 to 50 wt. %, based on the total amount of embedded particles;
- and
- the matrix material comprises a synthetic resin, comprising a material selected from the group consisting of melamine, epoxy, polyurethane, poiyamide, polyimide, latex, rubber, and a mixture thereof.
