Abstract

The invention provides graphene-phenolic resin glue, a preparation method thereof and a preparation method of an outdoor strand woven bamboo floor, and belongs to the technical field of floor manufacturing. The graphene-phenolic resin glue is prepared from the following components in parts by mass: 65 to 75 parts of phenolic resin glue, 5 to 8 parts of graphene, 4 to 5 parts of perchloro-ethylene resin, 2 to 4 parts of cosolvent, 2 to 3 parts of antioxidant, 0.5 to 1 part of flexibilizer, 1 to 2 parts of defoaming agent, 1 to 2 parts of wetting agent and 0.1 to 0.3 part of accelerant, the solid content of the phenolic resin glue is 100%. The graphene-phenolic resin glue is used for preparing the outdoor strand woven bamboo floor, and the purpose of improving the mildew resistance and the worm damage resistance of the outdoor strand woven bamboo floor can be achieved.

Description

technical field [0001] The invention belongs to the technical field of floor manufacturing, and in particular relates to a graphene-phenolic resin glue and a preparation method thereof, and a preparation method of an outdoor heavy bamboo floor. Background technique [0002] Heavy bamboo floor, commonly known as bamboo silk board, is a kind of bamboo floor. It is further improved on the basis of general bamboo floor, making it more beautiful and practical. The material selection of heavy bamboo flooring is more refined than that of ordinary bamboo flooring. It generally uses high-quality moso bamboo (or other bamboo species with similar material properties) with a bamboo age of more than four years as the material. After material selection, cooking, drying, hot pressing, etc. Produced through a series of strict technological processes. [0003] Bamboo flooring is commonly found in outdoor environments such as parks and communities. After being exposed to rain, wind, severe c...
