preparation example Construction

[0032] A second aspect of the present invention provides a preparation method of a gypsum-based imitation wood board and a wood square, the steps comprising:

[0033] S1: weigh silica sol, latex powder, chopped glass fiber, wood fiber, dispersant and / or water reducing agent, crystallizing agent, foaming agent and water by proportion, stir and foam at high speed to obtain foaming liquid; During the process, the stirring speed is 1500-2500 r / min, and the stirring time is 2-4 min. By adding silica sol and latex powder in the foaming process, the present invention can fully exert its synergistic effect, support the foam, keep the foam from collapsing for more than 4 hours, and avoid the performance of the gypsum product being reduced due to the premature collapse of the foam.

[0034] S2: Mix the above foaming liquid with gypsum powder, and stir at high speed to obtain a mixture; in this process, the stirring speed is 1500-2500 r / min, and the stirring time is 2-4 min.

[0035] S3...

Embodiment 1

[0060] The present embodiment provides a kind of gypsum base material imitation wood board and wooden square, and the specific preparation steps are as follows:

[0061] (1) Weigh 32g of silica sol, 10g of latex powder, 7.5g of chopped glass fiber, 4g of wood fiber H200, 1g of dispersant, 0.5g of water reducing agent, 0.5g of crystallizer, 1.5g of foaming agent and 350g of water. Put it into a stainless steel bowl, and stir at a high speed of 2000r / min for 2 minutes to foam to obtain a foaming liquid;

[0062] (2) slowly pour 500g β gypsum powder into the above-mentioned stainless steel bowl filled with foaming liquid and stir at a high speed of 2000r / min for 2min while pouring to obtain a mixture;

[0063] (3) Pour the above mixture into a mold, vibrate and scrape, and solidify at room temperature for 2 hours to obtain a gypsum substrate imitation wood board and a wood square. Among them, the size of the mold for imitation wood planks is 420mm*300mm*10mm, and the size of the...

Embodiment 2

[0065] The present embodiment provides a kind of gypsum base material imitation wood board and wooden square, and the specific preparation steps are as follows:

[0066] (1) Weigh 50g of silica sol, 30g of latex powder, 15g of chopped glass fiber, 5g of wood fiber H500A, 2g of dispersant, 1.5g of crystallizing agent, 2.5g of foaming agent and 230g of water and pour it into a stainless steel bowl. Stir at a high speed of 2500 r / min for 3 minutes to foam to obtain a foaming liquid;

[0067] (2) 600g α gypsum powder is slowly poured into the above-mentioned stainless steel bowl filled with foaming liquid and stirred at a high speed for 3min at a stirring rate of 2500r / min to obtain a mixture;

[0068] (3) Pour the above mixture into a mold, vibrate and scrape it flat, and solidify at room temperature for 3 hours to obtain a gypsum substrate imitation wood board and a wood square. Among them, the size of the mold for imitation wood planks is 420mm*300mm*10mm, and the size of the ...

Abstract

The invention discloses a gypsum base material imitation wood board and a wood square, a preparation method thereof and a composite gypsum board. The gypsum base material imitates wood planks and wooden squares, and the raw materials, in parts by weight, include: 80-120 parts of gypsum powder, 5-10 parts of silica sol, 2-10 parts of latex powder, 1-3 parts of chopped glass fiber, wood 0.5-1 part of fiber, 0.1-0.4 part of dispersant and / or water reducing agent, 0.1-0.3 part of crystallizing agent, 0.2-0.5 part of foaming agent and 45-70 parts of water. The gypsum products provided by the invention all have the advantages of low density and high strength, and have obvious effect of imitating wood. At the same time, according to different application occasions, products with different densities, flexural and compressive strengths, hardness and bending toughness can be produced.

Description

technical field [0001] The invention relates to the technical field of gypsum building materials, in particular to a gypsum base material imitation wood board and a wood square, a preparation method thereof and a composite gypsum board. Background technique [0002] Gypsum board is a building material made of building gypsum as the main raw material, mixed with appropriate additives and fibers, and processed. Gypsum board has the advantages of wide source of raw materials, no pollution, strong processing performance and simple construction method, and is widely used in architectural decoration. [0003] Although ordinary gypsum board has high strength and high hardness, its density is relatively large, which limits its application range to a certain extent. The gypsum board made by foaming the gypsum material has a lower density and has similar properties to wood, and can be used instead of wood products in many occasions. However, the existing gypsum foam board has high d...
