Embodiment 1
[0018] A preparation method for anti-dry cracking gypsum mortar, specifically comprising the following contents:
[0019] Step 1. Weigh 40 parts of desulfurized gypsum, 50 parts of quartz sand, 40 parts of lime calcium powder, 20 parts of expanded vitrified microbeads, 10 parts of fly ash, 1 part of polypropylene fiber and 5 parts of cement according to the weight ratio. 1 part, 3 parts of silicon dioxide, 1 part of water-repellent agent, 1 part of rubber powder, 2 parts of retarder, 2 parts of water-retaining agent and 0.5 part of water-reducing agent for standby;
[0020] Step 2. Add the above-mentioned desulfurized gypsum, quartz sand, lime calcium powder, expanded vitrified beads, fly ash, polypropylene fiber, and cement into the mixing tank in sequence, and stir while adding. The stirring time is 15 minutes, and the stirring speed is 2000r / min until the mixture is evenly mixed to obtain a mixture;
[0029] A preparation method for anti-dry cracking gypsum mortar, specifically comprising the following contents:
[0030] Step 1. Weigh 50 parts of desulfurized gypsum, 60 parts of quartz sand, 50 parts of lime calcium powder, 30 parts of expanded vitrified microbeads, 20 parts of fly ash, 2 parts of polypropylene fiber, and 7 parts of cement according to the weight ratio. 5 parts of silicon dioxide, 2 parts of water-repellent agent, 2 parts of rubber powder, 4 parts of retarder, 5 parts of water-retaining agent and 1.5 parts of water-reducing agent for standby;

Abstract
The invention provides a preparation method of anti-dry-crackinggypsummortar. The preparation method specifically comprises the following steps: weighing the following required raw materials in parts by weight: desulfurized gypsum, quartz sand, ash calciumpowder, expanded and vitrified micro bubbles, fly ash, polypropylene fibers, cement, silicon dioxide, a water repellent, rubber powder, a retarder, a water retaining agent and a water reducing agent for later use; sequentially adding the desulfurized gypsum, the quartz sand, the ash calciumpowder, the expanded and vitrified micro bubbles,the coal ash, the polypropylene fibers and the cement into a stirring tank, and stirring for 15-25 minutes at the stirring speed of 1500-2000 r / min while adding until the materials are uniformly mixed, so as to obtain a mixture; sequentially adding silicon dioxide, a water repellent, rubber powder, a retarder, a water retaining agent and a water reducing agent into the mixture, and uniformly mixing to obtain a gypsum mortar product. The added polypropylene fibers are good in workability and can be uniformly dispersed, crack propagation can be prevented, cracks can be refined, and the crack resistance of the mortar is effectively improved.
Description
technical field [0001] The invention relates to the technical field of building materials, in particular to a preparation method and application of an anti-dry cracking gypsum mortar. Background technique [0002] Mortar is a bonding substance used in building bricks. It is composed of a certain proportion of sand and cementing materials (cement, lime paste, clay, etc.) Or called cement lime mortar), lime mortar and clay mortar, mixed with inorganic cementitious material, fine aggregate and water in proportion, also known as lime mortar royal jelly. Mortar is divided into cement mortar, lime mortar, gypsum mortar and cement-lime mixed mortar according to the different materials used. Most of the existing gypsum mortars have the problem of easy cracking. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a preparation method and application of anti-dry cracking gypsum mortar to solve the problems in the above-menti...
