Wood fireproof glue and manufacturing process of fireproof plate

Abstract

The invention discloses wood fireproof glue, which is prepared by the following steps: stirring and heating magnesium chloride, polyvinyl alcohol, magnesium sulfate and water in a reaction vessel, reacting to generate a fireproof glue intermediate material, adding an auxiliary agent into the intermediate material while stirring to prepare the wood fireproof glue. The invention also discloses a fireproof plate prepared from the wood fireproof glue and a manufacturing process thereof. The fireproof plate comprises a fireproof plate sandwich layer composed of multiple solid wood blocks which aresuccessively distributed from left to right. Upper and lower sides of the fireproof plate sandwich layer are respectively provided with a fireproof wood chip layer which is formed by crisscrossed lamination of multiple wood chips according to the wood grain. Between the fireproof wood chip layer and the fireproof plate sandwich layer, between two adjacent solid wood blocks and between two adjacentwood chips is coated with the wood fireproof glue. The fireproof plate is prepared by steps of wood turning, final trimming, coating with the wood fireproof glue, cold pressing, drying, sanding and hot pressing.

Description

technical field [0001] The invention relates to the technical field of wood products, in particular to a wood fireproof glue and a manufacturing process of a fireproof board. Background technique [0002] Fireproof board, also known as fireproof board, is a refractory building material for surface decoration. It has rich surface colors, textures and special physical properties. It is widely used in interior decoration, furniture, kitchen cabinets, laboratory countertops, exterior walls and other fields. [0003] Existing fireproof boards usually include a core layer and a fireproof layer. The fireproof layer wraps the core layer to make a fireproof board. In the prior art, the fireproof layer is a mineral wool board, glass wool board, cement board, perlite board, and fireproof gypsum board. , metal plates and other fire-resistant wood chips made of chemical materials, etc. The above-mentioned fire-resistant boards have the advantages of fire-resistant and heat-insulating, ad...
