Embodiment 1

[0036]A flame-retardant wood-based panel with an inorganic rock finish, comprising an OSB base material and an inorganic rock decorative flame-retardant layer paved on the OSB base material, the inorganic rock decorative flame-retardant layer is composed of inorganic slurry and additives, wherein , the inorganic slurry includes calcium carbonate, calcium silicate, and silicon oxide and aluminum oxide that can enhance the strength and hardness of the inorganic rock decorative flame-retardant layer, and the auxiliary agent is a titanate coupling agent. The organic / inorganic coupling is carried out through the calcium carbonate in the OSB substrate and the inorganic slurry to realize a one-time coating forming process, which eliminates the secondary composite cementation process used in the prior art for the inorganic slurry rock decoration layer and the substrate layer , improve production efficiency, and effectively reduce costs (in addition to process simplification, the use of...

Embodiment 2

[0055] Similar to the examples, a flame retardant wood-based panel with inorganic rock finish includes an OSB base material and an inorganic rock decorative flame retardant layer paved on the OSB base material, the inorganic rock decorative flame retardant layer is composed of inorganic slurry and Auxiliary composition, wherein, the inorganic slurry includes calcium carbonate, calcium silicate, and silicon oxide and aluminum oxide that can enhance the strength and hardness of the inorganic rock decorative flame-retardant layer, and the auxiliary agent is a titanate coupling agent . The organic / inorganic coupling is carried out through the OSB substrate and calcium carbonate in the inorganic slurry. The thickness of the OSB substrate is 15mm. The raw material of the OSB substrate is poplar wood. The adhesive material used is MDI, and the formaldehyde emission can reach E NF class.

[0056] The preparation method of the inorganic rock veneer flame retardant wood-based panel com...

Embodiment 3

[0066] In this embodiment, the thickness of the plywood base material is 16.7mm, the raw material of the plywood base material is poplar, the adhesive material used is soybean vegetable protein adhesive, and the formaldehyde emission amount reaches E NF class.

[0067] A method for preparing an inorganic rock-faced flame-retardant wood-based panel, comprising the following steps,

[0068] Step 1: Sanding the base material with a fixed thickness, sanding the plywood base material on both sides, the abrasive belt is 120 mesh, and the sanding speed is 45m / min;

[0069] Step 2, preparation of inorganic slurry, adding natural mineral materials such as calcium carbonate, calcium silicate, silicon oxide and aluminum oxide in proportion, 120 parts by weight of calcium carbonate, 30 parts by weight of calcium silicate, and 10 parts by weight of silicon oxide , 15 parts by weight of alumina, stirring with a high-speed mixer, with a rotating speed of 3500r / min for 20min, then 1500r / min ...

Abstract

The invention discloses an inorganic rock facing flame-retardant artificial board and a preparation method thereof. The inorganic rock facing flame-retardant artificial board comprises a base material layer and further comprises an inorganic rock decoration flame-retardant layer arranged on the surface of the base material layer; the base material layer is selected from any one of a plywood base material, a core-board base material and an OSB base material, and the inorganic rock decoration flame-retardant layer is composed of inorganic slurry and an auxiliary agent, wherein the inorganic slurry comprises calcium carbonate, calcium silicate and inorganic filler capable of enhancing the strength and hardness of the inorganic rock decoration flame-retardant layer. The inorganic rock facing flame-retardant artificial board meets the flame-retardant requirement of indoor decoration boards, and meanwhile, the product has wide market space and economic value due to the high cost performance of the inorganic rock facing flame-retardant artificial board.

Description

Technical field: [0001] The invention relates to the field of building materials, in particular to an inorganic rock-faced flame-retardant wood-based panel and a preparation method thereof. Background technique: [0002] Since the country promulgated the hardcover delivery policy for real estate projects in 2018, the real estate, building materials, decoration and other industries have undergone earth-shaking changes. Real estate hardcover delivery, prefabricated buildings, green buildings, etc. have been put on the national strategic agenda. On September 4, 2020, 9 national departments jointly issued "Several Opinions on Accelerating the Industrialization of New Buildings", posing new challenges to decoration projects. The assembly process and material characteristics are rapidly developing towards modular production and integrated assembly features. [0003] Oriented strand board (OSB) is the main material used in wood structure building wall panels, roof panels, floor pa...
