Magnesite fireproof decoration integrated wall plate and manufacturing method thereof

Abstract

The invention relates to a magnesite fireproof decoration integrated wall plate, which comprises a magnesite decoration plate, adhesive layers and melamine impregnated paper. The melamine impregnatedpaper is bonded to the double faces of the magnesite decoration plate through the adhesive layers. A manufacturing method comprises the following preparation steps: a, the surface of the magnesite decoration plate with the water content being lower than 8% is sanded and polished; b, the surface is subjected to dust removing and purified; c, the surface of the magnesite plate is coated with a thermoset phenolic resin adhesive, 0.5% of a penetrant and 0.3% of a curing agent, wherein the penetrant and the curing agent are added in proportion; d, the melamine impregnated paper is flatly laid on the two faces of the pretreated magnesite plate, and press fit is conducted through a multi-layer hot-pressing laminating machine; and e, the plate is subjected to normal-temperature maintenance for 12h, then cut into corresponding specified sizes, and then grooved, groove openings use whole female groove butt-joint openings to form a finished product, and integrated splicing and fixing are conducted through anchoring pieces. The magnesite fireproof decoration integrated wall plate can be quickly assembled, and achieves the effects of fire prevention, environmental protection and waterproofing.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a magnesite fireproof decorative integrated wallboard and a manufacturing method thereof. Background technique [0002] As our country and countries around the world pay more and more attention to building fire protection, the use of wood-based combustible organic decorative panels in construction projects has been strictly limited, and existing inorganic fireproof panels such as gypsum boards, calcium silicate boards, and glass magnesium boards In terms of secondary processing performance, it cannot meet the requirements of primary construction and application, resulting in the need for secondary construction during the construction process, resulting in a long construction period and an increase in cost.

Problems solved by technology

[0002] As our country and countries around the world pay more and more attention to building fire protection, the use of wood-based combustible organic decorative panels in construction projects has been strictly limited, and existing inorganic fireproof panels such as gypsum boards, calcium silicate boards, and glass magnesium boards The secondary processing performance cannot meet the primary construction and application requirements, resulting in the need for secondary construction during the construction process, resulting in a long construction period and an increase in cost

[0003] Patent document CN 100398763C discloses a kind of exterior wall thermal insulation decorative board and its manufacturing method, but polystyrene board is still used as the thermal insulation layer, and its overall flame retardancy and durability are still unsatisfactory

In addition, although some inorganic composite materials are used as the insulation layer, there are serious quality defects in the products such as moisture absorption, halogen return, frosting, poor water resistance and weather resistance, or poor thermal insulation performance.
