Embodiment 1

[0016] First take each component (percentage by weight) according to the following proportioning ratio: 0.4% starch, 0.2% glass fiber, 0.04% foaming agent, 0.01% borax, 0.05% paper and 0.1% coagulant, and the remainder is gypsum; , prepared according to the following process:

[0017] a. Break the gypsum first;

[0018] b. Make paper into pulp in the pulp preparation tank, then add borax into the pulp preparation tank and stir with the pulp for 5-10 minutes, then send it into the pulp storage tank and stir for 5-25 minutes, and add borax to the pulp storage tank at the same time Glass fiber stirring for 5 to 25 minutes;

[0019] c. The pulp mixture prepared above, together with additives such as crushed gypsum powder, starch, foaming agent, and coagulant, enter the mixer for stirring, and then go to the forming platform for molding.

Embodiment 2～7

[0021] Prepare according to the components in the following table, and the preparation process is the same as in Example 1.

Abstract

The invention discloses a moisture-resistant and fire-resistant plasterboard, which comprises the following components (weight percentage): 0.4 to 1.2 percent of starch, 0.2 to 1.0 percent of fibreglass, 0.04 to 0.15 percent of vesicant, 0.01 to 0.08 percent of borax, 0.05 to 0.5 percent of paper and the left plaster. The invention also discloses a moisture-resistant and fire-resistant plasterboard preparation method, which comprises the following steps: a: first pulping paper into a pulp solution, then dissolving the borax into the pulp solution, then adding the fibreglass into the pulp solution to form a pulp mixture; b: mixing and stirring the pulp mixture with mashed land plaster, the starch and the vesicant. The invention not only has good fire-resistant performance, and has good moisture-resistant and rot-resistant performance. In addition, the preparation method also solves associated problem of the borax and the fibreglass in plaster crystal which can not be solved by drying adding boron in the prior art.

Description

technical field [0001] The invention relates to a preparation process of a moisture-resistant and fire-resistant gypsum board. Background technique [0002] Gypsum board is a material made of building gypsum as the main raw material. Because of its light weight, high strength, thinner thickness, convenient processing, and fire resistance, gypsum board is widely used in residential buildings, office buildings, and shops. , Hotels and other places, mainly used as sound-absorbing panels, interior partition walls, ground floor panels, etc. Patent 200410080357.1 discloses a fire-resistant gypsum board, which is mainly composed of gypsum, glass fiber, starch, foaming agent and other raw materials, and has good fire-resistant performance. But this gypsum board has poor moisture resistance and anti-mildew effect. In addition, although there are moisture-resistant and mildew-resistant gypsum boards on the market, they do not have good fire resistance. [0003] Under normal circum...
