Embodiment 1

[0078] The main steps of building panels using magnesium compounds mixed with plant fibers are as follows:

[0079] A. Weigh each component as shown in Table 1, fully mix the aggregate, modified modifier, and thickening and toughening agent, grind after mixing, carbonize at 68°C, and homogenize at 20°C;

[0080] B, processing powder: the powder after above-mentioned homogenization is added water and stirred according to the ratio of 1: 1, obtains pasty mixture;

[0081] C. Making boards: add fillers to the pasty mixture, stir evenly, and then spread it on the glass cloth, the cloth size is 13×5×5, and then stack the multi-layer glass cloth, and the twisted cloth used for the surface layer is 13 ×6 mesh, formed by rolling with rollers; width 122×length 244×thickness 1.2-1.5.

[0082] D. Curing: The temperature is 55 ℃, drying and curing for 7 days.

Embodiment 2

[0087] The main steps of building panels using magnesium compounds mixed with plant fibers are as follows:

[0088] A. Weigh each component as shown in Table 1, fully mix the aggregate, modified modifier, and thickening and toughening agent, grind after mixing, carbonize at 72°C, and homogenize at 22°C;

[0089] B, processing powder: the powder after above-mentioned homogenization is added water and stirred according to the ratio of 1: 1.2, obtains pasty mixture;

[0090] C. Making boards: add fillers to the pasty mixture, stir evenly, and then spread it on the glass cloth, the cloth size is 13×5×5, and then stack the multi-layer glass cloth, and the twisted cloth used for the surface layer is 13 ×6 mesh, formed by rolling with rollers; width 122×length 244×thickness 1.2-1.5.

[0091] D. Curing: temperature 65 ℃, drying and curing for 6 days.

Embodiment 3

[0093] The main steps of building panels using magnesium compounds mixed with plant fibers are as follows:

[0094] A. Weigh each component as shown in Table 1, fully mix the aggregate, modified modifier, and thickening and toughening agent, grind after mixing, carbonize at 65°C, and homogenize at 18°C;

[0095] B, processing powder: the powder after above-mentioned homogenization is added water and stirred according to the ratio of 1: 1.5, obtains pasty mixture;

[0096] C. Making boards: add fillers to the pasty mixture, stir evenly, and then spread it on the glass cloth, the cloth size is 13×5×5, and then stack the multi-layer glass cloth, and the twisted cloth used for the surface layer is 13 ×6 mesh, formed by rolling with rollers; width 122×length 244×thickness 1.2-1.5.

[0097] D. Curing: The temperature is 45 ℃, drying and curing for 8 days.

Abstract

The invention relates to a plate mainly manufactured by vegetable fiber, in particular to a building plate manufactured by mixing a magnesium compound with the vegetable fiber. The invention mainly aims at the defects that large usage of wooden plate damages the ecological environment, and so on and invents a building plate which has low price and environment friendly and easily-obtained materials, and is manufactured by mixing the magnesium compound with the vegetable fiber. The plate mainly comprises aggregate, a modifying agent, a tackifying-toughing agent and filling materials. The manufacturing steps are as follows: mixing, grinding, carbonizing and homogenizing the aggregate, the modifying agent and the tackifying-toughing agent, adding water to the obtained powder and stirring to obtain pasty mixture, adding the filling material to the pasty mixture and stirring, spreading the pasty mixture on glass silk cloth, piling up multi-layers of glass silk cloth, pressing the glass silk cloth by a roller and drying and curing.

Description

technical field [0001] The invention relates to a board mainly made of plant fiber, in particular to a building board made of magnesium compound mixed with plant fiber. Background technique [0002] At present, a large number of wooden building molds are used in building construction, such as compressed nine-story building molds, bamboo and wood building molds, etc. Due to the direct use of a large number of wooden materials, resources are wasted and the ecological balance is destroyed. At the same time, due to the defects of the wooden board itself, the quality of the project cannot be guaranteed. In response to the above problems, a large number of technologies for replacing wooden boards with composite boards have appeared. [0003] Such as a plant fiber magnesium oxychloride cement composite board whose domestic application number is 94110592.X, it is composed of magnesium oxychloride cement cementitious material, plant fiber, additives and a small amount of modifier i...
