Embodiment 1

[0039] refer to figure 1 , Embodiment 1 of the present invention provides a fire-retardant straw man-made composite board, its size area is about 1000mm×2000mm, its thickness is about 8 mm, the fire-retardant straw man-made composite board is a 3-layer composite structure, which includes about 6 mm Thick bare panel 1 and two veneer veneer layers 2,3. The bare panel 1 is sandwiched between the two veneer layers 2, 3 as a base panel. The two facing layers 2, 3 are glued on the bare panel 1 by phenolic resin.

Embodiment 2

[0041] see figure 2 , Embodiment 2 of the present invention provides a fire-retardant straw man-made composite board, its size area is about 1220mm×2440mm, its thickness is about 12 mm, the fire-retardant straw man-made composite board is a 5-layer composite structure, which includes about 6 mm Thick bare panel 1 and two layers of middle panels 4,5 and two layers of veneer veneer 2,3 with a total thickness of about 6 mm. The bare panel 1 acts as a base panel and is sandwiched between two layers of the middle panels 4 and 5 . The two facing layers 2 and 3 are the two outer surfaces of the flame-retardant straw man-made composite board, and are attached to the two middle boards 4 and 5 respectively. Wherein, the bare panel is mainly composed of 9 Kg of straw particles with a particle size of about 2 to 30 mm, 1.15 Kg of binder and 1 Kg of flame retardant, wherein the binder is phenolic resin glue, and the flame retardant The agent includes magnesium oxide 0.25kg; calcium sulf...

Abstract

The invention provides a flame-retardant straw artificial composite board. The flame-retardant straw artificial composite board comprises a naked panel and a decorative finish layer which is arranged on at least one surface of the naked panel, wherein the naked panel comprises the following raw materials in parts by weight: 7 to 8 parts of crop straw particles, 0.8 to 1 part of adhesion agent and 0.8 to 1 part of flame retardant, wherein the flame retardant comprises magnesium oxide, calcium sulfate, aluminum hydroxide, brucite and zinc borate. The flame-retardant straw artificial composite board has very high chemical, physical and mechanical properties of flame retardancy, water resistance, insect resistance and the like, and can be applied to various fields instead of wood-based panels. The invention also provides a manufacturing method for the flame-retardant straw artificial composite board. According to the manufacturing method, the raw materials are subjected to curing and shaping processing by adopting a normal temperature cold pressing molding technology; energy resources are greatly saved; the product performance can also be improved; the product has the functions of preventing water and preventing fire; meanwhile, the equipment cost can also be greatly reduced; the overall production process is green and pollution-free.

Description

technical field [0001] The invention relates to an artificial board and a manufacturing method thereof, in particular to a flame-retardant artificial composite board using straw as a main raw material 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 crop straw, wh...
