Embodiment 1

[0031] Such as figure 1 As shown, in parts by weight, measure each raw material according to the liquid material formula shown in Table 1-Example 1; add deionized water in the liquid material mixing tank, open the disperser of the mixing tank, and keep the rotating speed at 1000 rpm Minutes, add the emulsion into the liquid material mixing tank to disperse for 10 minutes, reduce the stirring speed to 800 rpm, then add the defoamer, dispersant and bactericide into the liquid material mixing tank, stir for 10 minutes, and finally add The color paste is used for coloring, and the liquid material can be packaged after stirring for 10 minutes;

[0032] In parts by weight, measure each raw material according to the powder formula shown in Table 2-Example 1: turn on the weightless powder mixer, keep the rotating speed at 600 rpm, then add white cement and high-strength gypsum to the powder mixing tank , add the heavy filler and light filler vitrified microspheres into the mixing tan...

Embodiment 2

[0034] The difference between Example 2 and Example 1 is that the formula of the liquid material is shown in Table 1-Example 2, and the formula of the powder material is shown in Table 2-Example 2.

Embodiment 3

[0036] The difference between this Example 3 and Example 1 is that its liquid material formula is shown in Table 1-Example 3, and its powder material formula is shown in Table 2-Example 3.

Abstract

The invention discloses double-component flame-retarding micro-bubble type external wall waterproof mortar and a preparation method thereof and relates to the technical field of waterproof materials.A liquid material is prepared from the following components: 100 to 400 parts of silicone acrylic emulsion, 0.5 to 5 parts of a de-foaming agent, 0.1 to 5 parts of a dispersant, 0.1 to 5 parts of fungicide and 400 to 900 parts of de-ionized water; a powder material is prepared from the following components: 50 to 500 parts of high-aluminum white cement, 5 to 20 parts of high-strength gypsum, 400 to 800 parts of heavy aggregate, 10 to 300 parts of vitrified microspheres, 0.1 to 10 parts of a water-retaining agent, 1 to 10 parts of a water reducing agent, 0.5 to 5 parts of a water repellent and1 to 15 parts of a cement foaming agent; the weight ratio of the liquid material to the powder material is 1 to (4 to 5). According to the double-component flame-retarding micro-bubble type external wall waterproof mortar disclosed by the invention, micro-bubbles are generated in a drying and hydration process of the mortar and the mortar has micro-expansion so that the strength is supplemented; the mortar has the advantages of shrinkage-cracking resistance, extremely strong water resistance, rapid curing speed, light weight, flame-retarding, heat-insulation and heat-preservation performance,high temperature resistance, capability of being constructed at low temperature in winter, no need of a protection layer and capability of being directly used in an exposed manner.

Description

technical field [0001] The invention relates to the technical field of waterproof materials, in particular to a two-component flame-retardant microbubble waterproof mortar for exterior walls and a preparation method thereof. Background technique [0002] Waterproof mortar is made of cement and fine aggregate as the main materials. Mainly used for basement anti-seepage and leakage treatment, repair of building roof and internal and external wall leakage, waterproof and anti-seepage of various pools and swimming pools, civil air defense projects, tunnels, granaries, kitchens, bathrooms, workshops, closed balconies and other places Waterproof and anti-seepage. [0003] Generally, the freshly mixed ordinary mortar should have good workability, and the hardened mortar should have the required strength and cohesive force. The workability of mortar is related to its fluidity and water retention, which is generally mastered according to construction experience or determined throug...
