Embodiment 1

[0029] This embodiment provides a flame-retardant straw particleboard, which has a three-layer structure and a thickness of 12 mm. The flame-retardant straw particleboard and the lower layer are formed by pressing the fine-grained straw particles after modification and sizing. The dense layer, the middle layer is a core layer formed by pressing the straw particles with coarse particle diameter after modification and sizing. The flame-retardant straw particleboard specifically includes the following raw materials: 36Kg of straw particles, 2.4Kg of E0 grade urea-formaldehyde resin, and 2Kg of flame retardant; wherein the 2Kg of flame retardant specifically includes the following raw materials: 0.625kg of magnesium oxide, 0.5kg of magnesium chloride , 0.125kg of trisodium phosphate, 0.625kg of polyvinyl alcohol and 0.125kg of ammonium polyphosphate.

[0030] refer to figure 1 , this embodiment also provides a method for manufacturing the above-mentioned flame-retardant straw par...

Embodiment 2

[0040] This embodiment provides a flame-retardant straw particleboard, which is different from Example 1 in that the flame-retardant straw particleboard specifically includes the following raw materials: 40Kg of straw particles, 5Kg of E0 grade urea-formaldehyde resin, and 2.5Kg of flame retardant; The flame retardant 2.5Kg specifically includes the following raw materials by weight: 0.75kg of magnesium oxide, 0.5kg of magnesium chloride, 0.25kg of trisodium phosphate, 0.75kg of polyvinyl alcohol and 0.25kg of ammonium polyphosphate.

[0041] The performance test of the finished product of the flame-retardant straw particleboard described in Example 2 is carried out below.

[0042] (1) Water resistance test: The flame-retardant straw particleboard with a thickness of 12 mm was placed in boiling water at 73°C for 3 hours and dried at 73°C for 2 hours. Then it was measured that the strength of the flame-retardant straw particleboard was 1 MPa, and the strength before boiling was...

Embodiment 3

[0046] This embodiment provides a flame-retardant straw particleboard, which is different from both Embodiment 1 and Embodiment 2 in that: the flame-retardant straw particleboard specifically includes the following raw materials: 42Kg of straw particles, 1.8Kg of E0 grade urea-formaldehyde resin, and a flame retardant 3Kg; wherein the flame retardant 3Kg specifically includes the following raw materials by weight: 0.9kg of magnesium oxide, 0.6kg of magnesium chloride, 0.3kg of trisodium phosphate, 0.9kg of polyvinyl alcohol and 0.3kg of ammonium polyphosphate.

[0047] The performance test of the finished product of the flame-retardant straw particleboard described in this embodiment is carried out below.

[0048] (1) Water resistance test: The flame-retardant straw particleboard with a thickness of 12 mm was placed in boiling water at 73°C for 3 hours and dried at 73°C for 2 hours. Then it was measured that the strength of the flame-retardant straw particleboard was 0.75 MPa,...

Abstract

The invention provides a flame-retardant straw shaving board. The flame-retardant straw shaving board comprises, by weight, 7-9 parts of straw particles, 0.5-1.5 parts of flame retardants and 0.3-1.0 part of binders, wherein the flame retardants comprise magnesium oxide, magnesium chloride, trisodium phosphate, polyvinyl alcohol and ammonium polyphosphate. The flame-retardant straw shaving board is good in flame retardance, water resistance and insect resistance and low in formaldehyde content and has good physical and mechanical performances; a wooden shaving board can be replaced by the flame-retardant straw shaving board which can be applied to the field of decoration of various buildings and manufacturing of furniture. The invention further provides a manufacturing method of the flame-retardant straw shaving board. The hot press molding technology is mainly adopted for modifying and shaping the raw materials, so that not only is the wood resource saved, but also the whole production process is environmentally friendly and free of pollution.

Description

technical field [0001] The invention relates to a flame-retardant artificial board and a manufacturing method thereof, in particular to a flame-retardant straw particleboard and a manufacturing method thereof. Background technique [0002] Particleboard has become an important part of wood-based panels due to its characteristics of low production investment, low energy consumption, low cost, and low quality requirements for raw materials. Among them, my country's annual output of crop straw that can be used as particleboard raw materials is about 600 million tons or more. However, due to technical limitations, the recycling rate of straw has not been high. In the prior art, straw particleboards manufactured with crop straws as part of the raw materials have begun to be used in furniture, packaging and other fields. Therefore, expanding the use of crop straws as particleboard raw materials is one of the effective ways to realize the recycling of straw resources. However, the...
