Problems solved by technology

However, the traditional use of straw is mainly as feed, fertilizer, fuel and paper-making raw materials. At present, the above-mentioned uses have been greatly reduced, especially crop straw has become a burden on modern agriculture. Straw burning not only causes air pollution, but also greatly wastes natural resources

Embodiment 1

[0029] Embodiment 1 of the present invention provides a large flame-retardant straw core board, whose size and area are about 1220mm×2440mm, and its thickness is about 10mm. Straw core board, two wooden veneers respectively attached to the upper and lower surfaces of the homogeneous straw core board, and two veneers respectively attached to the two wooden veneers, wherein each wooden veneer The thickness is about 1.2mm, and the thickness of each veneer is about 0.3mm. The homogeneous straw core board is used as a base board and sandwiched between two layers of the wood veneer. The wood veneer is a wood middle board. The two veneers are the two outer surfaces of the flame-retardant straw core board, which are respectively pasted on the two layers of the wooden veneer. Among them, the homogeneous straw core board is mainly composed of 8.5 kg of straw particles with a particle size of about 2 to 30 mm, and 2.05 kg of a flame-retardant adhesive. The raw materials of the flame-re...

Embodiment 2

[0051] Embodiment 2 of the present invention provides a large flame-retardant straw core board, which is basically the same as the flame-retardant straw core board provided in Embodiment 1. The difference is that this embodiment provides flame-retardant straw The size of the large core board is 1220mm×2440mm×12mm, the thickness of the homogeneous straw core board is about 8mm, the thickness of each wooden veneer is about 1.6mm, and the thickness of each veneer is about 0.4mm; the homogeneous straw The core board is mainly composed of 8 kg of straw particles with a particle size of about 5-40 mm, and 2.12 kg of flame-retardant adhesives. The raw materials of the flame-retardant adhesive include 0.48 kg of magnesium chloride, 0.32 kg of magnesium oxide, and 0.6 kg of polyvinyl alcohol. , 0.2kg of water glass, 0.04kg of stone acid and 0.48kg of ammonium polyphosphate.

Abstract

The invention provides an antiflaming straw big core board. The antiflaming straw big core board comprises two wood single boards and a homogenization straw core board arranged between the two wood single boards. The homogenization straw core board comprises, by mass, 8 parts to 9 parts of straw particles and 1.8 parts to 2.4 parts of an antiflaming binding agent, wherein the antiflaming binding agent comprises raw material including magnesium chloride, magnesium oxide, polyvinyl alcohol, sodium silicate, tartaric acid and ammonium polyphosphate. The antiflaming straw big core board has the good chemical properties of inflaming retarding, water prevention, mosquito prevention and the like and has the good physical mechanical performance, a wood large core board can be replaced with the antiflaming straw big core board, and the antiflaming straw big core board can be applied to various fields. The invention further provides a manufacturing method of the antiflaming straw big core board. The manufacturing method is simple and environment-friendly.

Description

technical field [0001] The invention relates to a large core board and a manufacturing method thereof, in particular to a flame-retardant straw large core 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 2014, 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. However, the traditional use of straw is mainly as feed, fertilizer, fuel and paper-making raw materials. At present, the above-mention...
