Problems solved by technology

However, due to the high viscosity of inorganic adhesives in the production of inorganic particleboard, it is difficult to control the uniformity of sizing, which will affect the strength of the board to a certain extent.
In addition, due to the density of inorganic particleboard (usually at 1.2g / cm 3 above) is large, resulting in a large weight, so it is difficult to popularize and apply in furniture production

Abstract

The invention discloses a lightweight high-strength inorganic shaving board. The lightweight high-strength inorganic shaving board is prepared by mixing at least wood or non-wood shavings, an inorganic adhesive and sponge particles in the weight ratio of (40 to 60) to (100 to 120) to (1 to 3). A preparation method of the lightweight high-strength inorganic shaving board approximately comprises thefollowing steps: spraying the inorganic adhesive in the surfaces of the sponge particles and mixing uniformly; adding the wood or non-wood shavings and mixing uniformly; paving a mixture into a plateblank, and performing hot pressing to obtain a semi-finished product; and drying, edging and performing sanding treatment to obtain the lightweight high-strength inorganic shaving board after the semi-finished product is stacked. According to the lightweight high-strength inorganic shaving board disclosed by the invention, the application uniformity of the inorganic adhesive is effectively improved, and the density of the inorganic shaving board is effectively reduced to 0.8 to 1.0 g / m<3>, so that the weight of the inorganic shaving board is reduced; and moreover, the lightweight high-strength inorganic shaving board does not release free formaldehyde, and is waterproof, fireproof, high in mechanical strength and suitable to be popularized and applied in furniture production.

Description

technical field [0001] The invention belongs to the field of furniture and decoration material manufacturing, and in particular relates to a light-weight and high-strength inorganic particle board and a preparation method thereof. Background technique [0002] Inorganic particle board is a kind of artificial board prepared by combining inorganic adhesive and wood or non-wood shavings through a certain molding process. Inorganic particle board has the advantages of no free formaldehyde release, good waterproof and fireproof performance, and can be widely used in building wall materials, indoor and outdoor decoration materials and other fields. However, due to the high viscosity of inorganic adhesives in the production of inorganic particleboard, it is difficult to control the uniformity of sizing, which will affect the strength of the board to a certain extent. In addition, due to the density of inorganic particleboard (usually at 1.2g / cm 3 (above) are large, resulting in a...
