[0002] As one of the main building cementing materials, gypsum has an irreplaceable role, but its poor waterproof performance affects its scope of use. At present, the main methods to improve the waterproof performance of gypsum hardened body are: adding waterproof materials to the gypsum slurry , to form a waterproof layer on the surface of the internal particles of the hardened gypsum body, such as adding bitumen stearic acid to

Embodiment Construction
[0007] Take by weight 10% of stearic acid; 2.0% of polyvinyl alcohol; 50% of cement; 2.0% of borate; 93% of hemihydrate gypsum;
[0008] Its preparation method is:
[0009] (1) Put appropriate amount of water, cement, polyvinyl alcohol, borate, and hemihydrate gypsum into the tank according to the formula and stir evenly.
[0010] (2) Slowly add the stearic acid and the crosslinking agent of the formulated amount into the tank under low-speed stirring, and stir evenly.
[0011] (3) In the state of stirring, put the accelerator into the tank, stir evenly, and use it.

The invention relates to a waterproofing agent for a desulfurization gypsum block, and the waterproofing agent mainly comprises stearic acid, polyvinyl alcohol, cement, borate, semi-hydrated gypsum, accelerants, cross-linking agents, and the like. The waterproofing agent for the desulfurization gypsum block, which is disclosed by the invention, can change the structure of holes, pores and capillary holes which are positioned in the surface inside a gypsum product so as to change the surface from a hydrophilic surface to a hydrophobic surface, thereby preventing the moisture from invading and achieving the characteristics of waterproofing and the like.
Description
technical field [0001] The invention relates to a waterproofing agent for desulfurized gypsum blocks, which belongs to the field of building materials. Background technique [0002] As one of the main building cementing materials, gypsum has an irreplaceable role, but its poor waterproof performance affects its scope of use. At present, the main methods to improve the waterproof performance of gypsum hardened body are: adding waterproof materials to the gypsum slurry , to form a waterproof layer on the surface of the internal particles of the hardened gypsum body, such as adding bitumen stearic acid to the gypsum, and spraying the hydrophobic material directly on the surface of the hardened gypsum body to form a water-repellent layer on the surface of the product. Improving the short-term waterproof performance of gypsum has a good effect, but its waterproof mechanism is to directly infiltrate a single material into the product, but the long-term waterproof effect cannot be ...
