Problems solved by technology

[0003] The plastering mortar generally has a certain drying shrinkage during the hardening process, which makes the surface of the plastering mortar have tiny pores, and the external moisture can easily penetrate into the interior of the mortar from these tiny pores, resulting in the compressive strength of the plastering mortar after wetting. reduced, thus exhibiting poorer durability

Embodiment 1-5

[0055] S1, the polyacrylic acid of 10.5kg, the tributyl phosphate of 3kg and the hydroxypropyl methylcellulose of 3.6kg are mixed, and the mass ratio of polyacrylic acid, tributyl phosphate, hydroxypropyl methylcellulose is 3.5: 1:1.2, the stirring speed is 120r / min, the temperature is raised to 65°C during the stirring process and the temperature is kept constant for 45min to obtain the microcapsule core liquid;

[0056] S2, take 9kg of microcapsule core liquid and mix with 5kg of diatomite, that is, the mass ratio of diatomite to mortar microcapsule core liquid is 1:1.8, mix and stir for 20min at a stirring speed of 120r / min, mix well and place 18h, obtain microcapsules;

[0057] S3. Mix epoxy resin, plasticizer and microcapsules in the amount shown in Table 2, and mix and stir for 15min at a stirring speed of 120r / min to obtain a microcapsule mixture;

[0058] S4. Add cement, aluminosilicate zeolite powder, admixture and half of the water to the microcapsule mixture, and m...

Embodiment 6

[0064] The difference from Example 5 is only that: 13.8 kg of microcapsule core liquid is mixed with 6 kg of diatomite, that is, the mass ratio of diatomite to microcapsule core liquid is 1:2.3 to obtain microcapsules.

Embodiment 7

[0066] The only difference from Example 5 is: 11kg of polyacrylic acid, 2kg of tributyl phosphate and 3.4kg of hydroxypropyl methylcellulose are mixed, that is, polyacrylic acid, tributyl phosphate, hydroxypropyl methylcellulose The mass ratio was 5.5:1:1.7, and the microcapsule core liquid was obtained.

Abstract

The application relates to the field of mortar materials, and specifically discloses a water-resistant plastering mortar and a preparation method thereof. A water-resistant plastering mortar whose raw materials include cement, sand, water, fly ash, anhydrous calcium sulfate, aluminosilicate zeolite powder, microcapsules, epoxy resin, plasticizer, and admixture, wherein micro The capsule is made of diatomite as the capsule wall, and polyacrylic acid, tributyl phosphate, and hydroxypropyl methylcellulose are used as the capsule core; the preparation method is: uniformly mixing epoxy resin, plasticizer and microcapsules to obtain microcapsules. Capsule mix; add cement, aluminosilicate zeolite powder, admixture and half of the water into the microcapsule mix, and mix evenly to obtain mortar premix; mix sand, fly ash, anhydrous calcium sulfate, and The remaining half of the water is added to the mortar premix to obtain a water-resistant plastering mortar. A water-resistant plastering mortar preparation method of the present application can prepare a water-resistant plastering mortar with good water resistance.

Description

technical field [0001] The application relates to the field of mortar materials, more specifically, it relates to a water-resistant plastering mortar and a preparation method thereof. Background technique [0002] Plastering mortar is applied to the plastering of exterior walls or interior walls in construction and decoration projects. Plastering mortar forms a smooth and beautiful hard layer after the wall is smoothed and hardened. Plastering is usually judged by the compressive strength of the mortar Construction performance of mortar. [0003] The plastering mortar generally has a certain drying shrinkage during the hardening process, which makes the surface of the plastering mortar have tiny pores, and the external moisture can easily penetrate into the interior of the mortar from these tiny pores, resulting in the compressive strength of the plastering mortar after wetting. reduced, resulting in poorer durability. Contents of the invention [0004] In order to impro...
