Embodiment 1

[0021] Such as figure 1 Shown, a kind of production technology of building panel comprises the following steps:

[0022] (1), using the magnesium oxychloride cement board as the base material, use a sander to carry out coarse sanding on the front and back of the magnesium oxychloride cement board, and the grain size number of the coarse sand belt of the sander is 20#-60#;

[0023] (2) Use a sander to finely sand the front of the magnesium oxychloride cement board. The grain size of the fine sand belt of the sander is 80#-200#, and the positive and negative deviation of the front after fine sanding is 0.02 mm-0.5mm (the board surface has no obvious unevenness);

[0024] (3), apply adhesive on the front side, stick the fabric, carry out hot pressing with a hot press, and then carry out cold pressing with a cold press to obtain the building board of the present invention.

[0025] According to actual production needs, the gluing process of the step (3) is machine-coated with a ...

Embodiment 2

[0029] Another production process for building panels, comprising the following steps:

[0030] (1), using the magnesium oxychloride cement board as the base material, use a sander to carry out coarse sanding on the front and back of the magnesium oxychloride cement board, and the grain size number of the coarse sand belt of the sander is 20#-60#;

[0031] (2) Use a sander to finely sand the front of the magnesium oxychloride cement board. The grain size of the fine sand belt of the sander is 80#-200#, and the positive and negative deviation of the front after fine sanding is 0.02 mm-0.5mm (the board surface has no obvious unevenness);

[0032] (3) Apply polyurethane styrofoam on the front, the amount of glue applied is 20g-300g / m 2 , glued to the wood, and hot pressed with a hot press, the hot pressing pressure is 1Kg-25Kg / cm 2 , the hot pressing time is 4-15 minutes, and then cold pressing with a cold press, the cold pressing pressure is 1Kg-25Kg / cm 2 , cold pressing time...

Abstract

The invention discloses a production technology of building sheets, comprising the following steps: (1), taking the magnesium oxychloride cement board as ground mass, coarse sanding on the right side and back side of the magnesium oxychloride cement board by a sanding machine, the particle size of a coarse sanding belt of the sanding machine is 20#-60 #; (2), finishing sanding on the right side of the magnesium oxychloride cement board by the sanding machine, the particle size of a finishing sanding belt of the sanding machine is 80#-600#, the positive and negative deviation of the right side of the magnesium oxychloride cement board after the finishing sanding is 0.02mm-0.5mm; 3), coating adhesive on the right side, sticking on fabric on the right side, hot pressing by a hot press, and cold pressing by a cold press to prepare the building sheets of the invention. The invention also discloses a building sheet prepared by the production technology of building sheets. The invention also discloses five applications of the building sheets.

Description

technical field [0001] The invention relates to the production technology of building boards, in particular to a production process of building boards, the building boards produced by the process and applications thereof. Background technique [0002] At present, the construction industry is developing rapidly, the construction technology is also very mature, and there are many types of building panels, but the production process of building panels is relatively complicated, the production cycle is long, the production efficiency is low, and the production cost is high. There is only one kind of building board, and one kind of building board has only one use. Contents of the invention [0003] In order to overcome the shortcomings of the prior art above, the present invention provides a production process of building panels with simple process and low cost. [0004] The purpose of the present invention is achieved through the following technical solutions: the production ...
