Embodiment Construction

[0026] The technical scheme of the present invention is described below with specific examples, but protection scope of the present invention is not limited thereto:

[0027] A waterproof and alkali-resistant decorative mortar, the preparation process is as follows:

[0028] 1) The design coordination ratio is shown in Table 2, and the raw materials are prepared according to the data in the table;

[0029] The metakaolin is a white 1250-mesh superfine powder, and its composition is the same as in Table 1.

[0030] The fly ash is preferably grade II or above ash, the silica fume is white 800 mesh silica powder, and the quartz sand adopts three specifications of 20-40 mesh, 40-70 mesh, and 325 mesh in a mass ratio of 9 : 3:1 mixed to obtain; said water glass modulus is 2.0-2.5; the length of pp fiber is 3mm.

[0031] 2) Prepare the activator: mix the required caustic soda with water, stir and dissolve for 10 minutes, then add the required water glass and stir evenly, then let ...

Abstract

The invention belongs to the technical field of building materials and particularly relates to waterproof and anti-alkali decorating mortar and a preparation method thereof. The decorating mortar is prepared from the following raw materials in percentage by mass: 20%-30% of metakaolin, 2%-3% of coal ash, 3%-5% of silica fume, 40%-55% of quartz sand, 5%-15% of water glass, 3%-7% of caustic soda, 6%-15% of water, 0.2%-1.2% of an inorganic mineral pigment and 0.1%-0.3% of PP fiber. The waterproof and anti-alkali decorating mortar is low in whiskering risk, high in structural compactness and strength, good in water resistance and excellent weather resistance.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a waterproof and alkali-resistant decorative mortar and a preparation method thereof. Background technique [0002] Decorative mortar is a kind of mortar used as a building finish. In practical applications, it is often necessary to add a certain amount of inorganic mineral pigments for coloring. After that, various construction tools are used to create colorful decorative effects with the toned decorative mortar. At present, decorative mortar is widely used in the exterior walls of buildings, which can play a very good protective and decorative effect on the base of the exterior walls. [0003] However, traditional decorative mortars are mostly cement-based inorganic materials, so there are many inherent shortcomings of cement-based materials, such as low strength, easy efflorescence, poor elasticity, and high water absorption. In order to solve the above problems, ...
