Embodiment 1

[0039] refer to figure 1 , Embodiment 1 of the present invention provides a kind of flame-retardant composite board, and its dimension area is about 1000mm×2000mm, and its thickness is about 8mm, and this flame-retardant composite board is a 3-layer composite structure, and it comprises about 6mm thick bare panel 1 and two veneer veneer layers 2,3. The homogeneous bare panel 1 is sandwiched between the two veneer layers 2, 3 as a base panel. The two finishing layers 2 and 3 are respectively pasted on the top surface and the bottom surface of the homogeneous bare panel 1 through inorganic glue glass. Wherein, the homogeneous bare panel is mainly composed of 8.5 Kg of straw particles with a particle size of about 2 to 30 mm, 1 Kg of water glass binder and 0.5 Kg of a flame retardant, and the raw material of the flame retardant includes magnesium oxide 0.11 kg, calcium sulfate 0.12kg, aluminum hydroxide 0.14kg, brucite 0.04kg, zinc molybdate 0.025kg and zinc borate 0.065kg, the...

Embodiment 2

[0041] see figure 2 , Embodiment 2 of the present invention provides a kind of flame-retardant composite board, and its dimension area is about 1220mm * 2440mm, and its thickness is about 12mm, and this flame-retardant composite board is a 5-layer composite structure, and it comprises about 6mm thick homogeneous Bare panel 1 and two intermediate panels 4, 5 with a total thickness of about 6 mm and two veneer veneer layers 2, 3. The homogeneous bare panel 1 is used as a base panel and is sandwiched between two layers of the intermediate panels 4 and 5 . The middle boards 4 and 5 are wooden middle boards. The two facing layers 2, 3 are the two outer surfaces of the flame-retardant composite board, and are attached to the two middle boards 4, 5 respectively. Among them, the homogeneous bare panel is mainly composed of 9Kg of straw particles with a particle size of about 2 to 30 mm, 0.9Kg of water glass binder and 0.52Kg of a flame retardant, and the raw material of the flame r...

Abstract

The invention provides a flame retardant composite board. The flame retardant composite board comprises a homogeneous naked panel and a facing layer arranged on at least one surface of the homogeneous naked panel, wherein the homogeneous naked panel is prepared from raw materials of, based on weight parts, 65-98.5 parts of plant straw particles, 3-10 parts of binder and 3-10 parts of fire retardant, wherein the fire retardant is prepared from raw materials of magnesium oxide, calcium sulfate, aluminum hydroxide, brucite, zinc molybdate and zinc borate. The flame retardant composite board has good chemical properties of fire retarding, water prevention, insect prevention and the like, and good physical and mechanical properties, can replace wood artificial boards, and is used in various fields. The invention further provides a manufacture method of the flame retardant composite board. The manufacture method of the flame retardant composite board mainly adopts a normal temperature cold press molding technology to solidify and shape the raw materials of the naked panel, not only greatly saves energy, but also improves product performance, enables the flame retardant composite board to have water prevention and fire prevention functions, and simultaneously can substantially reduce equipment cost, achieves a whole green production process, and does not cause pollution during the whole production process.

Description

technical field [0001] The invention relates to an artificial composite board and a manufacturing method thereof, in particular to a flame-retardant composite board using a non-wood fiber board as a base board and a manufacturing method thereof. Background technique [0002] my country is a country with a serious shortage of forest resources, but at the same time it is a big producer of wood-based panels. In 2013, the output of wood-based panels in my country exceeded 270 million cubic meters, and the manufacture of wood-based panels alone consumed more than 400 million cubic meters of forest resources. The huge demand for forest resources The contradiction with the lack of resources has become an important factor restricting the country's economic development. On the other hand, my country produces more than 900 million tons of crop residues every year, which is a huge renewable resource. [0003] The basic board in the straw man-made composite board is mainly made of non-w...
