Description

Technical Field

[0001] The invention relates to the technical field of special mortar preparation for industrial floors, and in particular to a special mortar for anti-skid industrial floors and a preparation method thereof. Background Art

[0002] When preparing mortar, cement, sand and other raw materials are mixed according to a certain formula ratio, and the mixing equipment is kept stirring continuously until the required slurry fluidity and uniformity are achieved. The mixed mortar can be applied to the surface of the industrial floor and solidified to form a construction site floor for daily use.

[0003] During the preparation process of existing mortar, only cement, sand and daily additives are stirred and mixed, which can easily cause problems of poor adhesion and crack resistance, reduce the stability and reliability of the mortar quality, and at the same time, when used on a relatively wet surface, the mortar tends to become slippery, increasing the risk of slipping.

[0004] Therefore, in order to solve the problem of low anti-slip property of the above-mentioned mortar, a special anti-slip industrial floor mortar can be designed. Summary of the invention

[0005] In order to overcome the problem of low slip resistance when using mortar.

[0007] Cement includes ordinary Portland cement and wear-resistant cement. The Portland cement is not less than grade 32.5R. The mass ratio of ordinary Portland cement to wear-resistant cement is 7:3.

[0008] Preferably, silicate cement has higher early and long-term strength, which can enhance the overall bearing capacity and durability of the mortar. Wear-resistant cement adds wear-resistant particles, and the combination with silicate cement further increases the wear resistance of the mortar, makes the industrial floor more durable and wear-resistant, extends the service life of the floor, reduces the frequency of maintenance and replacement, and reduces the overall cost. The combination of fine aggregate, wear-resistant aggregate and filler improves the surface smoothness of the mortar, making the floor or wall easier to clean and maintain, increases the density and strength of the mortar while improving the wear resistance of the mortar, so that the mortar achieves the best balance in construction, performance and maintenance. The addition of anti-slip agent forms tiny protrusions or structures on the surface of the mortar, increases the friction of the ground, reduces the risk of sliding when people walk, and thus improves safety. The mixture of plasticizer, adhesive, water reducer and air entraining agent can improve the strength and durability of the mortar, improve its compression resistance, bending resistance and freeze-thaw resistance, and further ensure the strength and density of the mortar, thereby improving the durability and bearing capacity of the mortar structure and ensuring the structural quality and performance of the mortar.

[0009] Preferably, the fine aggregate includes natural sand and stone chips, the particle size of the natural sand is less than 4.75 mm, and the particle size of the stone chips ranges from 0 to 5 mm.

[0010] Preferably, the additives include an anti-slip agent, a plasticizer, an adhesive, a water reducer and an air entraining agent, and the mass ratio of the anti-slip agent, the plasticizer, the adhesive, the water reducer and the air entraining agent is 1-5:0.1-1:5-10:0.1-0.5:0.1-1.

[0011] Preferably, the wear-resistant aggregate includes quartz sand, white porcelain sand and pomegranate sand. The particle size of the quartz sand ranges from 0.1 to 5 mm, the particle size of the white porcelain sand ranges from 0.5 to 1.5 mm, and the particle size of the pomegranate sand is about 0.1 mm.

[0012] Preferably, the filler comprises micro beads and mineral powder, and the mass ratio of the micro beads to the mineral powder is 5-15:5-20.

[0013] Preferably, the anti-slip agent is any one of silica sand, polymer particles and mineral particles.

[0014] Preferably, the plasticizer is a polycarboxylic acid and the adhesive is a polymer modified latex.

[0015] Preferably, the water reducing agent is any one of polycarboxylic acid and fatty alcohol polyoxyethylene ether.

[0016] A method for preparing a special mortar for anti-skid industrial flooring, comprising the special mortar for anti-skid industrial flooring as described above, and the steps are as follows:

[0017] Step 1: Pour the measured ordinary Portland cement and wear-resistant cement into the mixing equipment, add water to stir the two, stir for 1-2 minutes to make the materials fully mixed;

[0018] Step 2: Keep the mixing equipment running, pour the natural sand and stone chips mixture in batches during mixing, add an appropriate amount of water, and continue to stir with cement for 1-2 minutes to form industrial floor mortar;

[0019] Step 3: Add wear-resistant aggregate, filler and industrial floor mortar respectively, add appropriate amount of water during the stirring process, add the additives into the industrial floor mortar in batches, and continue stirring for 1-2 minutes to obtain the anti-slip industrial floor mortar.

[0020] Beneficial effects of the present invention:

[0021] Portland cement has high early and long-term strength, which can enhance the overall bearing capacity and durability of mortar. Wear-resistant cement increases wear-resistant particles, and the combination with Portland cement further increases the wear resistance of mortar, making industrial floors more durable and wear-resistant, extending the service life of the floor, reducing the frequency of maintenance and replacement, and reducing overall costs. The combination of fine aggregate, wear-resistant aggregate and filler improves the surface smoothness of the mortar, making the floor or wall easier to clean and maintain, increasing the density and strength of the mortar while improving the wear resistance of the mortar, so that the mortar achieves the best balance in construction, performance and maintenance. The addition of anti-slip agent forms tiny protrusions or structures on the surface of the mortar, increases the friction of the ground, and reduces the risk of sliding when people walk, thereby improving safety. The mixture of plasticizer, adhesive, water reducer and air entraining agent can improve the strength and durability of the mortar, improve its compression, bending and freeze-thaw resistance, and further ensure the strength and density of the mortar, thereby improving the durability and bearing capacity of the mortar structure and ensuring the structural quality and performance of the mortar.
