Special gypsum plaster board for building construction

Abstract

The invention discloses a special gypsum plaster board for building construction, and relates to the field of building materials. The invention relates to a waterproof and hydrophobic gypsum board, which is prepared from the following raw materials in parts by weight: 0.5 to 2 parts of modified starch, 0.2 to 0.8 part of retarder, 80 to 100 parts of gypsum powder, 0.5 to 2 parts of water reducing agent, 40 to 50 parts of water, 1 to 30 parts of aerogel powder, 10 to 30 parts of foam particles and 10 to 20 parts of waterproof and hydrophobic material. The waterproof and hydrophobic gypsum board is prepared from the following raw materials in parts by weight: 0.5 to 2 parts of modified starch, 0.2 to 0.8 part of retarder, 80 to 100 parts of gypsum powder, 0.5 to 2 parts of water reducing agent, 40 to 50 parts of water, 1 to 30 parts of aerogel powder, 10 to 30 parts of foam particles and 10 to 20 parts of waterproof and hydrophobic material. The gypsum plaster board has the beneficial effects that the overall weight of the gypsum plaster board can be effectively reduced by adding the aerogel powder and the foam particles, so that the gypsum plaster board is convenient to manually carry and mount in building construction, and the waterproof hydrophobic material is additionally arranged on the surface of the gypsum plaster board, so that the waterproof capability of the gypsum plaster board is improved, and the waterproof effect of the gypsum plaster board is improved. The problems of blackening and mildewing of the gypsum plaster board are reduced, and long-time transportation of the gypsum plaster board is facilitated.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a special paper-faced gypsum board for building construction. Background technique [0002] Paper-faced gypsum board is a board made of building gypsum as the main raw material, mixed with appropriate amount of additives and fibers as the board core, and made of special cardboard as the surface protection. Paper-faced gypsum board has the characteristics of light weight, sound insulation, heat insulation, strong processing performance, and simple construction method. Paper-faced gypsum board can be divided into four categories: ordinary, water-resistant, fire-resistant and moisture-proof. The energy consumption of gypsum board is 78% lower than that of cement. And less investment, large production capacity, simple process, easy for large-scale production; 2, light weight: use paper-faced gypsum board as partition wall, the weight is only 1 / 15 of the brick wall of the same thic...

Problems solved by technology

[0004] The purpose of the present invention is to aim at the prior art, when the gypsum board is used in building construction, and the weight is relatively heavy, it is not conducive to workers to carry and install, and the waterproof and hydrophobic ability of the gypsum board is poor, which is easy to cause The gypsum board is blackened and moldy, and it is inconvenient for the gypsum board to be transported for a long time. To provide a special gypsum board for construction
