Embodiment 1

[0029] A self-defoaming and anti-foaming putty, which includes by weight: 65-85 parts of 240-260 mesh double fly powder, 1-5 parts of ordinary Portland cement, 10-20 parts of ordinary white sand 150-200 mesh, less 2~6 parts of water agent, 1~3 parts of bentonite, 2~7 parts of cellulose ether, 2~6 parts of starch ether, 3~5 parts of redispersible latex powder; 7~14 parts of defoaming moderator.

[0030] Among them, the defoaming mixture includes 2 to 4 parts of diatom mud and 5 to 10 parts of a mixture of non-crystalline silicon dioxide. role.

[0031] In the production process, defoaming means that when a large number of bubbles are generated in the system, after adding the defoaming agent, its molecules spread on the surface of the foam, quickly paved, and form a very thin double film layer, which further diffuses, penetrates, and invades in layers. Thereby replacing the thin walls of the original foam. Due to its low surface tension, it is easy to flow to the liquid with h...

Embodiment 2

[0040] A self-defoaming and antifoaming putty, a kind of self-defoaming and antifoaming putty, contains by weight: 250 mesh double fly powder 75 parts, ordinary portland cement 3 parts, ordinary white sand 175 mesh 15 parts, water reducing 4 parts of agent, 2 parts of bentonite, 4.5 parts of cellulose ether, 4 parts of starch ether, 4 parts of redispersible latex powder; 10.5 parts of defoaming moderator.

[0041] Among them, the defoaming mixture includes 3 parts of diatom mud and 7.5 parts of a mixture of non-crystalline silicon dioxide. The diatom mud plays the role of suppressing foam, and the mixture of non-crystalline silicon dioxide plays the role of defoaming.

[0042] The preparation method in this example is similar to Example 1, the difference is: in step S2, the temperature is 70°C, and the rotating speed is 500r / min; in step 3, the rotating speed is 900r / min; in step S4, the rotating speed is 1000r / min min, the temperature is 90°C.

Embodiment 3

[0044] A self-defoaming and anti-foaming putty, which contains by weight: 85 parts of 260 mesh Shuangfei powder, 5 parts of ordinary Portland cement, 20 parts of ordinary white sand 200 mesh, 6 parts of water reducing agent, 3 parts of bentonite, cellulose 7 parts of ether, 6 parts of starch ether, 5 parts of redispersible latex powder; 14 parts of defoaming moderator.

[0045] Wherein, the defoaming mixture includes 4 parts of diatom mud and 10 parts of a mixture of non-crystalline silicon dioxide. The diatom mud plays a role in suppressing foam, and the mixture of non-crystalline silicon dioxide plays a role of defoaming.

[0046] The preparation method in this example is similar to Example 1, the difference is: in step S2, the temperature is 80°C, and the rotating speed is 800r / min; in step 3, the rotating speed is 1000r / min; in step S4, the rotating speed is 1200r / min min, the temperature is 95°C.

[0047]In order to verify the difference between this program and ordinary...

Abstract

The invention relates to a self-defoaming and anti-foaming putty, which comprises the following components in parts by weight: 65-85 parts of Shuangfei powder, 1-5 parts of ordinary Portland cement, 2-6 parts of water reducer, 3~5 parts of redispersible latex powder, 2~7 parts of cellulose ether, 7~14 parts of antifoaming mixture; said antifoaming mixture includes diatom ooze, non-crystalline silica The mixture, diatom mud plays the role of inhibiting foam, and the mixture of non-crystalline silicon dioxide plays the role of defoaming. Also disclosed is a preparation method of the self-defoaming and anti-foaming putty. The beneficial effects achieved by the invention are: the air bubbles are easily eliminated, the air bubbles can be effectively suppressed, and the air bubbles are not easily generated during the brushing process.

Description

technical field [0001] The invention relates to the technical field of putty, in particular to a self-defoaming and antifoaming putty and a preparation method thereof. Background technique [0002] During the construction process, if the putty powder foams, it will seriously affect the final delivery effect of the house. The sources of the bubbles mainly include the following two aspects: 1. Mechanical stirring is used after the putty powder is added with water, which is generated during high-speed stirring; 2. The base layer of the wall Uneven, when the putty is applied, the air in the wall cannot diffuse inward, but can only bulge outward, forming air bubbles. If these bubbles are not eliminated in time, it will cause surface defects and affect the final effect of the product. Therefore, it is very important for putty products to quickly defoam and suppress foam. [0003] At present, for air bubbles, it can be reduced by repeated smearing by workers, but this will serious...
