Abstract

A surface protection compound, in particular a compound for the non- flammable water-resistant non-hazardous biocidal surface protection of wood, or paper, or textile, or plastic, which contains an aqueous silicate solution which contains 93 to 98 wt% of an aqueous solution of potassium silicate, 1 to 6 wt% of aluminium hydroxide and, 0.5 to 1.5 wt% of stabiliser of the aqueous solution of potassium silicate.

Description

Technical field [0001] The present invention relates to a composite for surface protection, especially for wood, or paper, or fabric, non-flammable, waterproof, harmless killing surface protected. It contains aqueous solution of silicate. Background technique [0002] From the current technologies, a variety of coatings for wood protection are known, which differ in the expected use of the composition. The simplest compound is present in a coating only for wood surface termination, which is only protected from mechanical and chemical effects and is used to decorate. Higher quality coatings also prevent atmospheric impact, water, UV radiation, etc. The coating that provides comprehensive wood also contains additional special additives, such as killing bobes, UV absorbers, flame retardants, and the like. The amount of pigment in the coating also plays a lot of growth in the amount of radiation, resulting in yellowing and browning, and then plays with water, ash. [0003] A self-ext...
